SQLAlchemy provides a full suite +of well known enterprise-level persistence patterns, +designed for efficient and high-performing database +access, adapted into a simple and Pythonic domain +language. + +Major SQLAlchemy features include: + +* An industrial strength ORM, built + from the core on the identity map, unit of work, + and data mapper patterns. These patterns + allow transparent persistence of objects + using a declarative configuration system. + Domain models + can be constructed and manipulated naturally, + and changes are synchronized with the + current transaction automatically. +* A relationally-oriented query system, exposing + the full range of SQL's capabilities + explicitly, including joins, subqueries, + correlation, and most everything else, + in terms of the object model. + Writing queries with the ORM uses the same + techniques of relational composition you use + when writing SQL. While you can drop into + literal SQL at any time, it's virtually never + needed. +* A comprehensive and flexible system + of eager loading for related collections and objects. + Collections are cached within a session, + and can be loaded on individual access, all + at once using joins, or by query per collection + across the full result set. +* A Core SQL construction system and DBAPI + interaction layer. The SQLAlchemy Core is + separate from the ORM and is a full database + abstraction layer in its own right, and includes + an extensible Python-based SQL expression + language, schema metadata, connection pooling, + type coercion, and custom types. +* All primary and foreign key constraints are + assumed to be composite and natural. Surrogate + integer primary keys are of course still the + norm, but SQLAlchemy never assumes or hardcodes + to this model. +* Database introspection and generation. Database + schemas can be "reflected" in one step into + Python structures representing database metadata; + those same structures can then generate + CREATE statements right back out - all within + the Core, independent of the ORM. + +SQLAlchemy's philosophy: + +* SQL databases behave less and less like object + collections the more size and performance start to + matter; object collections behave less and less like + tables and rows the more abstraction starts to matter. + SQLAlchemy aims to accommodate both of these + principles. +* An ORM doesn't need to hide the "R". A relational + database provides rich, set-based functionality + that should be fully exposed. SQLAlchemy's + ORM provides an open-ended set of patterns + that allow a developer to construct a custom + mediation layer between a domain model and + a relational schema, turning the so-called + "object relational impedance" issue into + a distant memory. +* The developer, in all cases, makes all decisions + regarding the design, structure, and naming conventions + of both the object model as well as the relational + schema. SQLAlchemy only provides the means + to automate the execution of these decisions. +* With SQLAlchemy, there's no such thing as + "the ORM generated a bad query" - you + retain full control over the structure of + queries, including how joins are organized, + how subqueries and correlation is used, what + columns are requested. Everything SQLAlchemy + does is ultimately the result of a developer-initiated + decision. +* Don't use an ORM if the problem doesn't need one. + SQLAlchemy consists of a Core and separate ORM + component. The Core offers a full SQL expression + language that allows Pythonic construction + of SQL constructs that render directly to SQL + strings for a target database, returning + result sets that are essentially enhanced DBAPI + cursors. +* Transactions should be the norm. With SQLAlchemy's + ORM, nothing goes to permanent storage until + commit() is called. SQLAlchemy encourages applications + to create a consistent means of delineating + the start and end of a series of operations. +* Never render a literal value in a SQL statement. + Bound parameters are used to the greatest degree + possible, allowing query optimizers to cache + query plans effectively and making SQL injection + attacks a non-issue. + +Documentation +------------- + +Latest

A migrations tool +offers the following functionality: + +* Can emit ALTER statements to a database in order to change + the structure of tables and other constructs +* Provides a system whereby "migration scripts" may be constructed; + each script indicates a particular series of steps that can "upgrade" a + target database to a new version, and optionally a series of steps that can + "downgrade" similarly, doing the same steps in reverse. +* Allows the scripts to execute in some sequential manner. + +The goals of Alembic are: + +* Very open ended and transparent configuration and operation. A new + Alembic environment is generated from a set of templates which is selected + among a set of options when setup first occurs. The templates then deposit a + series of scripts that define fully how database connectivity is established + and how migration scripts are invoked; the migration scripts themselves are + generated from a template within that series of scripts. The scripts can + then be further customized to define exactly how databases will be + interacted with and what structure new migration files should take. +* Full support for transactional DDL. The default scripts ensure that all + migrations occur within a transaction - for those databases which support + this (Postgresql, Microsoft SQL Server), migrations can be tested with no + need to manually undo changes upon failure. +* Minimalist script construction. Basic operations like renaming + tables/columns, adding/removing columns, changing column attributes can be + performed through one line commands like alter_column(), rename_table(), + add_constraint(). There is no need to recreate full SQLAlchemy Table + structures for simple operations like these - the functions themselves + generate minimalist schema structures behind the scenes to achieve the given + DDL sequence. +* "auto generation" of migrations. While real world migrations are far more + complex than what can be automatically determined, Alembic can still + eliminate the initial grunt work in generating new migration directives + from an altered schema. The ``--autogenerate`` feature will inspect the + current status of a database using SQLAlchemy's schema inspection + capabilities, compare it to the current state of the database model as + specified in Python, and generate a series of "candidate" migrations, + rendering them into a new migration script as Python directives. The + developer then edits the new file, adding additional directives and data + migrations as needed, to produce a finished migration. Table and column + level changes can be detected, with constraints and indexes to follow as + well. +* Full support for migrations generated as SQL scripts. Those of us who + work in corporate environments know that direct access to DDL commands on a + production database is a rare privilege, and DBAs want textual SQL scripts. + Alembic's usage model and commands are oriented towards being able to run a + series of migrations into a textual output file as easily as it runs them + directly to a database. Care must be taken in this mode to not invoke other + operations that rely upon in-memory SELECTs of rows - Alembic tries to + provide helper constructs like bulk_insert() to help with data-oriented + operations that are compatible with script-based DDL. +* Non-linear, dependency-graph versioning. Scripts are given UUID + identifiers similarly to a DVCS, and the linkage of one script to the next + is achieved via human-editable markers within the scripts themselves. + The structure of a set of migration files is considered as a + directed-acyclic graph, meaning any migration file can be dependent + on any other arbitrary set of migration files, or none at + all. Through this open-ended system, migration files can be organized + into branches, multiple roots, and mergepoints, without restriction. + Commands are provided to produce new branches, roots, and merges of + branches automatically. +* Provide a library of ALTER constructs that can be used by any SQLAlchemy + application. The DDL constructs build upon SQLAlchemy's own DDLElement base + and can be used standalone by any application or script. +* At long last, bring SQLite and its inability to ALTER things into the fold, + but in such a way that SQLite's very special workflow needs are accommodated + in an explicit way that makes the most of a bad situation, through the + concept of a "batch" migration, where multiple changes to a table can + be batched together to form a series of instructions for a single, subsequent + "move-and-copy" workflow. You can even use "move-and-copy" workflow for + other databases, if you want to recreate a table in the background + on a busy system. + +Documentation and status of Alembic is at

Multiple changes + can also be specified at once and the backend should + "do the right thing", emitting each change either + separately or together as the backend allows. + + MySQL has special requirements here, since MySQL + cannot ALTER a column without a full specification. + When producing MySQL-compatible migration files, + it is recommended that the ``existing_type``, + ``existing_server_default``, and ``existing_nullable`` + parameters be present, if not being altered. + + Type changes which are against the SQLAlchemy + "schema" types :class:`~sqlalchemy.types.Boolean` + and :class:`~sqlalchemy.types.Enum` may also + add or drop constraints which accompany those + types on backends that don't support them natively. + The ``existing_type`` argument is + used in this case to identify and remove a previous + constraint that was bound to the type object. + + :param table_name: string name of the target table. + :param column_name: string name of the target column, + as it exists before the operation begins. + :param nullable: Optional; specify ``True`` or ``False`` + to alter the column's nullability. + :param server_default: Optional; specify a string + SQL expression, :func:`~sqlalchemy.sql.expression.text`, + or :class:`~sqlalchemy.schema.DefaultClause` to indicate + an alteration to the column's default value. + Set to ``None`` to have the default removed. + :param comment: optional string text of a new comment to add to the + column. + :param new_column_name: Optional; specify a string name here to + indicate the new name within a column rename operation. + :param type\_: Optional; a :class:`~sqlalchemy.types.TypeEngine` + type object to specify a change to the column's type. + For SQLAlchemy types that also indicate a constraint (i.e. + :class:`~sqlalchemy.types.Boolean`, :class:`~sqlalchemy.types.Enum`), + the constraint is also generated. + :param autoincrement: set the ``AUTO_INCREMENT`` flag of the column; + currently understood by the MySQL dialect. + :param existing_type: Optional; a + :class:`~sqlalchemy.types.TypeEngine` + type object to specify the previous type. This + is required for all MySQL column alter operations that + don't otherwise specify a new type, as well as for + when nullability is being changed on a SQL Server + column. It is also used if the type is a so-called + SQLAlchemy "schema" type which may define a constraint (i.e. + :class:`~sqlalchemy.types.Boolean`, + :class:`~sqlalchemy.types.Enum`), + so that the constraint can be dropped. + :param existing_server_default: Optional; The existing + default value of the column. Required on MySQL if + an existing default is not being changed; else MySQL + removes the default. + :param existing_nullable: Optional; the existing nullability + of the column. Required on MySQL if the existing nullability + is not being changed; else MySQL sets this to NULL. + :param existing_autoincrement: Optional; the existing autoincrement + of the column. Used for MySQL's system of altering a column + that specifies ``AUTO_INCREMENT``. + :param existing_comment: string text of the existing comment on the + column to be maintained. Required on MySQL if the existing comment + on the column is not being changed. + :param schema: Optional schema name to operate within.

In some cases, +we also note alternative representations which do not require this package. + +## Install + +```bash +pip install annotated-types +``` + +## Examples + +```python +from typing import Annotated +from annotated_types import Gt, Len, Predicate + +class MyClass: + age: Annotated[int, Gt(18)] # Valid: 19, 20, ... + # Invalid: 17, 18, "19", 19.0, ... + factors: list[Annotated[int, Predicate(is_prime)]] # Valid: 2, 3, 5, 7, 11, ... + # Invalid: 4, 8, -2, 5.0, "prime", ... + + my_list: Annotated[list[int], Len(0, 10)] # Valid: [], [10, 20, 30, 40, 50] + # Invalid: (1, 2), ["abc"], [0] * 20 +``` + +## Documentation + +_While `annotated-types` avoids runtime checks for performance, users should not +construct invalid combinations such as `MultipleOf("non-numeric")` or `Annotated[int, Len(3)]`. +Downstream implementors may choose to raise an error, emit a warning, silently ignore +a metadata item, etc., if the metadata objects described below are used with an +incompatible type - or for any other reason!_ + +### Gt, Ge, Lt, Le + +Express inclusive and/or exclusive bounds on orderable values - which may be numbers, +dates, times, strings, sets, etc. Note that the boundary value need not be of the +same type that was annotated, so long as they can be compared: `Annotated[int, Gt(1.5)]` +is fine, for example, and implies that the value is an integer x such that `x > 1.5`. + +We suggest that implementors may also interpret `functools.partial(operator.le, 1.5)` +as being equivalent to `Gt(1.5)`, for users who wish to avoid a runtime dependency on +the `annotated-types` package. + +To be explicit, these types have the following meanings: + +* `Gt(x)` - value must be "Greater Than" `x` - equivalent to exclusive minimum +* `Ge(x)` - value must be "Greater than or Equal" to `x` - equivalent to inclusive minimum +* `Lt(x)` - value must be "Less Than" `x` - equivalent to exclusive maximum +* `Le(x)` - value must be "Less than or Equal" to `x` - equivalent to inclusive maximum + +### Interval + +`Interval(gt, ge, lt, le)` allows you to specify an upper and lower bound with a single +metadata object. `None` attributes should be ignored, and non-`None` attributes +treated as per the single bounds above. + +### MultipleOf + +`MultipleOf(multiple_of=x)` might be interpreted in two ways: + +1. Python semantics, implying `value % multiple_of == 0`, or +2. [JSONschema semantics](https://json-schema.org/draft/2020-12/json-schema-validation.html#rfc.section.6.2.1), + where `int(value / multiple_of) == value / multiple_of`. + +We encourage users to be aware of these two common interpretations and their +distinct behaviours, especially since very large or non-integer numbers make +it easy to cause silent data corruption due to floating-point imprecision. + +We encourage libraries to carefully document which interpretation they implement. + +### MinLen, MaxLen, Len + +`Len()` implies that `min_length <= len(value) <= max_length` - lower and upper bounds are inclusive. + +As well as `Len()` which can optionally include upper and lower bounds, we also +provide `MinLen(x)` and `MaxLen(y)` which are equivalent to `Len(min_length=x)` +and `Len(max_length=y)` respectively. + +`Len`, `MinLen`, and `MaxLen` may be used with any type which supports `len(value)`. + +Examples of usage: + +* `Annotated[list, MaxLen(10)]` (or `Annotated[list, Len(max_length=10)]`) - list must have a length of 10 or less +* `Annotated[str, MaxLen(10)]` - string must have a length of 10 or less +* `Annotated[list, MinLen(3)]` (or `Annotated[list, Len(min_length=3)]`) - list must have a length of 3 or more +* `Annotated[list, Len(4, 6)]` - list must have a length of 4, 5, or 6 +* `Annotated[list, Len(8, 8)]` - list must have a length of exactly 8 + +#### Changed in v0.4.0 + +* `min_inclusive` has been renamed to `min_length`, no change in meaning +* `max_exclusive` has been renamed to `max_length`, upper bound is now **inclusive** instead of **exclusive** +* The recommendation that slices are interpreted as `Len` has been removed due to ambiguity and different semantic + meaning of the upper bound in slices vs. `Len` + +See [issue #23](https://github.com/annotated-types/annotated-types/issues/23) for discussion. + +### Timezone + +`Timezone` can be used with a `datetime` or a `time` to express which timezones +are allowed. `Annotated[datetime, Timezone(None)]` must be a naive datetime. +`Timezone[...]` ([literal ellipsis](https://docs.python.org/3/library/constants.html#Ellipsis)) +expresses that any timezone-aware datetime is allowed. You may also pass a specific +timezone string or [`tzinfo`](https://docs.python.org/3/library/datetime.html#tzinfo-objects) +object such as `Timezone(timezone.utc)` or `Timezone("Africa/Abidjan")` to express that you only +allow a specific timezone, though we note that this is often a symptom of fragile design. + +#### Changed in v0.x.x + +* `Timezone` accepts [`tzinfo`](https://docs.python.org/3/library/datetime.html#tzinfo-objects) objects instead of + `timezone`, extending compatibility to [`zoneinfo`](https://docs.python.org/3/library/zoneinfo.html) and third party libraries. + +### Unit + +`Unit(unit: str)` expresses that the annotated numeric value is the magnitude of +a quantity with the specified unit. For example, `Annotated[float, Unit("m/s")]` +would be a float representing a velocity in meters per second. + +Please note that `annotated_types` itself makes no attempt to parse or validate +the unit string in any way. That is left entirely to downstream libraries, +such as [`pint`](https://pint.readthedocs.io) or +[`astropy.units`](https://docs.astropy.org/en/stable/units/). + +An example of how a library might use this metadata: + +```python +from annotated_types import Unit +from typing import Annotated, TypeVar, Callable, Any, get_origin, get_args + +# given a type annotated with a unit: +Meters = Annotated[float, Unit("m")] + + +# you can cast the annotation to a specific unit type with any +# callable that accepts a string and returns the desired type +T = TypeVar("T") +def cast_unit(tp: Any, unit_cls: Callable[[str], T]) -> T | None: + if get_origin(tp) is Annotated: + for arg in get_args(tp): + if isinstance(arg, Unit): + return unit_cls(arg.unit) + return None + + +# using `pint` +import pint +pint_unit = cast_unit(Meters, pint.Unit) + + +# using `astropy.units` +import astropy.units as u +astropy_unit = cast_unit(Meters, u.Unit) +``` + +### Predicate + +`Predicate(func: Callable)` expresses that `func(value)` is truthy for valid values. +Users should prefer the statically inspectable metadata above, but if you need +the full power and flexibility of arbitrary runtime predicates... here it is. + +For some common constraints, we provide generic types: + +* `LowerCase = Annotated[T, Predicate(str.islower)]` +* `UpperCase = Annotated[T, Predicate(str.isupper)]` +* `IsDigit = Annotated[T, Predicate(str.isdigit)]` +* `IsFinite = Annotated[T, Predicate(math.isfinite)]` +* `IsNotFinite = Annotated[T, Predicate(Not(math.isfinite))]` +* `IsNan = Annotated[T, Predicate(math.isnan)]` +* `IsNotNan = Annotated[T, Predicate(Not(math.isnan))]` +* `IsInfinite = Annotated[T, Predicate(math.isinf)]` +* `IsNotInfinite = Annotated[T, Predicate(Not(math.isinf))]` + +so that you can write e.g. `x: IsFinite[float] = 2.0` instead of the longer +(but exactly equivalent) `x: Annotated[float, Predicate(math.isfinite)] = 2.0`. + +Some libraries might have special logic to handle known or understandable predicates, +for example by checking for `str.isdigit` and using its presence to both call custom +logic to enforce digit-only strings, and customise some generated external schema. +Users are therefore encouraged to avoid indirection like `lambda s: s.lower()`, in +favor of introspectable methods such as `str.lower` or `re.compile("pattern").search`. + +To enable basic negation of commonly used predicates like `math.isnan` without introducing introspection that makes it impossible for implementers to introspect the predicate we provide a `Not` wrapper that simply negates the predicate in an introspectable manner. Several of the predicates listed above are created in this manner. + +We do not specify what behaviour should be expected for predicates that raise +an exception. For example `Annotated[int, Predicate(str.isdigit)]` might silently +skip invalid constraints, or statically raise an error; or it might try calling it +and then propagate or discard the resulting +`TypeError: descriptor 'isdigit' for 'str' objects doesn't apply to a 'int' object` +exception. We encourage libraries to document the behaviour they choose. + +### Doc + +`doc()` can be used to add documentation information in `Annotated`, for function and method parameters, variables, class attributes, return types, and any place where `Annotated` can be used. + +It expects a value that can be statically analyzed, as the main use case is for static analysis, editors, documentation generators, and similar tools. + +It returns a `DocInfo` class with a single attribute `documentation` containing the value passed to `doc()`. + +This is the early adopter's alternative form of the [`typing-doc` proposal](https://github.com/tiangolo/fastapi/blob/typing-doc/typing_doc.md). + +### Integrating downstream types with `GroupedMetadata` + +Implementers may choose to provide a convenience wrapper that groups multiple pieces of metadata. +This can help reduce verbosity and cognitive overhead for users. +For example, an implementer like Pydantic might provide a `Field` or `Meta` type that accepts keyword arguments and transforms these into low-level metadata: + +```python +from dataclasses import dataclass +from typing import Iterator +from annotated_types import GroupedMetadata, Ge + +@dataclass +class Field(GroupedMetadata): + ge: int | None = None + description: str | None = None + + def __iter__(self) -> Iterator[object]: + # Iterating over a GroupedMetadata object should yield annotated-types + # constraint metadata objects which describe it as fully as possible, + # and may include other unknown objects too. + if self.ge is not None: + yield Ge(self.ge) + if self.description is not None: + yield Description(self.description) +``` + +Libraries consuming annotated-types constraints should check for `GroupedMetadata` and unpack it by iterating over the object and treating the results as if they had been "unpacked" in the `Annotated` type. The same logic should be applied to the [PEP 646 `Unpack` type](https://peps.python.org/pep-0646/), so that `Annotated[T, Field(...)]`, `Annotated[T, Unpack[Field(...)]]` and `Annotated[T, *Field(...)]` are all treated consistently. + +Libraries consuming annotated-types should also ignore any metadata they do not recongize that came from unpacking a `GroupedMetadata`, just like they ignore unrecognized metadata in `Annotated` itself. + +Our own `annotated_types.Interval` class is a `GroupedMetadata` which unpacks itself into `Gt`, `Lt`, etc., so this is not an abstract concern. Similarly, `annotated_types.Len` is a `GroupedMetadata` which unpacks itself into `MinLen` (optionally) and `MaxLen`. + +### Consuming metadata + +We intend to not be prescriptive as to _how_ the metadata and constraints are used, but as an example of how one might parse constraints from types annotations see our [implementation in `test_main.py`](https://github.com/annotated-types/annotated-types/blob/f59cf6d1b5255a0fe359b93896759a180bec30ae/tests/test_main.py#L94-L103). + +It is up to the implementer to determine how this metadata is used. +You could use the metadata for runtime type checking, for generating schemas or to generate example data, amongst other use cases. + +## Design & History + +This package was designed at the PyCon 2022 sprints by the maintainers of Pydantic +and Hypothesis, with the goal of making it as easy as possible for end-users to +provide more informative annotations for use by runtime libraries. + +It is deliberately minimal, and following PEP-593 allows considerable downstream +discretion in what (if anything!) they choose to support. Nonetheless, we expect +that staying simple and covering _only_ the most common use-cases will give users +and maintainers the best experience we can. If you'd like more constraints for your +types - follow our lead, by defining them and documenting them downstream! diff --git a/venv/lib/python3.12/site-packages/annotated_types-0.8.0.dist-info/RECORD b/venv/lib/python3.12/site-packages/annotated_types-0.8.0.dist-info/RECORD new file mode 100644 index 0000000..3bcb37f --- /dev/null +++ b/venv/lib/python3.12/site-packages/annotated_types-0.8.0.dist-info/RECORD @@ -0,0 +1,10 @@ +annotated_types-0.8.0.dist-info/INSTALLER,sha256=zuuue4knoyJ-UwPPXg8fezS7VCrXJQrAP7zeNuwvFQg,4 +annotated_types-0.8.0.dist-info/METADATA,sha256=YUmFsnj2Abjvhj-CeDuZHMOtpLifWS63HHxIxfLvIpg,15009 +annotated_types-0.8.0.dist-info/RECORD,, +annotated_types-0.8.0.dist-info/WHEEL,sha256=lCkmxWfQsSc9CfIClYeavTdQeEX2toPqufh9gI35EQA,87 +annotated_types-0.8.0.dist-info/licenses/LICENSE,sha256=_hBJiEsaDZNCkB6I4H8ykl0ksxIdmXK2poBfuYJLCV0,1083 +annotated_types/__init__.py,sha256=pxBKTUObJ6n3T8C-I2ubobeDHmBEAmgCogWrwSmKm8g,13273 +annotated_types/__pycache__/__init__.cpython-312.pyc,, +annotated_types/__pycache__/test_cases.cpython-312.pyc,, +annotated_types/py.typed,sha256=47DEQpj8HBSa-_TImW-5JCeuQeRkm5NMpJWZG3hSuFU,0 +annotated_types/test_cases.py,sha256=2GdHKstXuBzpf3iXKCjmvFZpyk2zP9Hm9kXGGDhGBo4,6310 diff --git a/venv/lib/python3.12/site-packages/annotated_types-0.8.0.dist-info/WHEEL b/venv/lib/python3.12/site-packages/annotated_types-0.8.0.dist-info/WHEEL new file mode 100644 index 0000000..7401812 --- /dev/null +++ b/venv/lib/python3.12/site-packages/annotated_types-0.8.0.dist-info/WHEEL @@ -0,0 +1,4 @@ +Wheel-Version: 1.0 +Generator: hatchling 1.31.0 +Root-Is-Purelib: true +Tag: py3-none-any diff --git a/venv/lib/python3.12/site-packages/annotated_types-0.8.0.dist-info/licenses/LICENSE b/venv/lib/python3.12/site-packages/annotated_types-0.8.0.dist-info/licenses/LICENSE new file mode 100644 index 0000000..d99323a --- /dev/null +++ b/venv/lib/python3.12/site-packages/annotated_types-0.8.0.dist-info/licenses/LICENSE @@ -0,0 +1,21 @@ +The MIT License (MIT) + +Copyright (c) 2022 the contributors + +Permission is hereby granted, free of charge, to any person obtaining a copy +of this software and associated documentation files (the "Software"), to deal +in the Software without restriction, including without limitation the rights +to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the Software is +furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in all +copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

High-level networking (TCP, UDP and UNIX sockets) + + * `Happy eyeballs`_ algorithm for TCP connections (more robust than that of asyncio on Python + 3.8) + * async/await style UDP sockets (unlike asyncio where you still have to use Transports and + Protocols) + +* A versatile API for byte streams and object streams +* Inter-task synchronization and communication (locks, conditions, events, semaphores, object + streams) +* Worker threads +* Subprocesses +* Subinterpreter support for code parallelization (on Python 3.13 and later) +* Asynchronous file I/O (using worker threads) +* Signal handling +* Asynchronous versions of the functools_ and itertools_ modules + +AnyIO also comes with its own pytest_ plugin which also supports asynchronous fixtures. +It even works with the popular

MIT](https://img.shields.io/badge/license-MIT-C06524)](https://github.com/hynek/argon2-cffi-bindings/blob/main/LICENSE) +[![PyPI version](https://img.shields.io/pypi/v/argon2-cffi-bindings)](https://pypi.org/project/argon2-cffi-bindings/) +[![PyPI - Python Version](https://img.shields.io/pypi/pyversions/argon2-cffi-bindings.svg)](https://pypi.org/project/argon2-cffi-bindings) + +*argon2-cffi-bindings* provides low-level [CFFI](https://cffi.readthedocs.io/) bindings to the official implementation of the [Argon2] password hashing algorithm. + + +The currently vendored Argon2 commit ID is [**`f57e61e`**](https://github.com/P-H-C/phc-winner-argon2/commit/f57e61e19229e23c4445b85494dbf7c07de721cb). + + +> [!NOTE] +> If you want to hash passwords in an application, this package is **not** for you. +> Have a look at [*argon2-cffi*] with its high-level abstractions! + +These bindings have been extracted from [*argon2-cffi*] and it remains its main consumer. +However, they may be used by other packages that want to use the Argon2 library without dealing with C-related complexities. + + +## Usage + +*argon2-cffi-bindings* is available from [PyPI](https://pypi.org/project/argon2-cffi-bindings/). +The provided CFFI bindings are compiled in API mode. + +Best effort is given to provide binary wheels for as many platforms as possible. + + +### Disabling Vendored Code + +A copy of [Argon2] is vendored and used by default, but can be disabled if *argon2-cffi-bindings* is installed using: + +```console +$ env ARGON2_CFFI_USE_SYSTEM=1 \ + python -Im pip install --no-binary=argon2-cffi-bindings argon2-cffi-bindings +``` + + +### Overriding Automatic SSE2 Detection + +Usually the build process tries to guess whether or not it should use [SSE2](https://en.wikipedia.org/wiki/SSE2)-optimized code (see [`_ffi_build.py`](https://github.com/hynek/argon2-cffi-bindings/blob/main/src/_argon2_cffi_bindings/_ffi_build.py) for details). +This can go wrong and is problematic for cross-compiling. + +Therefore you can use the `ARGON2_CFFI_USE_SSE2` environment variable to control the process: + +- If you set it to ``1``, *argon2-cffi-bindings* will build **with** SSE2 support. +- If you set it to ``0``, *argon2-cffi-bindings* will build **without** SSE2 support. +- If you set it to anything else, it will be ignored and *argon2-cffi-bindings* will try to guess. + +However, if our heuristics fail you, we would welcome a bug report. + + +### Python API + +Since this package is intended to be an implementation detail, it uses a private module name to prevent your users from using it by accident. + +Therefore you have to import the symbols from `_argon2_cffi_bindings`: + +```python +from _argon2_cffi_bindings import ffi, lib +``` + +Please refer to [*cffi* documentation](https://cffi.readthedocs.io/en/latest/using.html) on how to use the `ffi` and `lib` objects. + +The list of symbols that are provided can be found in the [`_ffi_build.py` file](https://github.com/hynek/argon2-cffi-bindings/blob/main/src/_argon2_cffi_bindings/_ffi_build.py). + +[Argon2]:

+ +[^1]: They are clearly using specific code for a specific encoding even if covering most of them. +[^2]: Chardet 7 replaced the historical LGPL-licensed implementation with an AI-assisted rewrite, initially distributed under MIT and later under 0BSD. The original author [contests](https://github.com/chardet/chardet/issues/327) that the rewrite was sufficiently independent to permit relicensing, while Chardet's maintainer maintains that it is a new, non-derivative implementation. A separate [discussion](https://github.com/chardet/chardet/issues/334) raises questions about copyright ownership and licensing of substantially AI-generated code. Neither unresolved question is presented here as settled law. The concern is broader than whether ideas, APIs, or observable behavior are copyrightable. Independent implementations are essential to open-source competition. The ethical question is whether a maintainer with extensive access to a reciprocal project's source, architecture, tests, behavior, community, and reputation can use an LLM to recreate the same product under the same package identity, then treat the generated implementation as a provenance reset that extinguishes the project's reciprocal licensing obligations and contributor expectations. Responsible AI use in open source requires more than producing text that differs from the historical source: it requires transparent provenance, respect for project lineage, meaningful attribution, accountable human review, and consideration for the social agreement under which earlier contributors participated. If automated rewriting becomes an accepted way to retain a project's name, users, and accumulated reputation while discarding its reciprocal license, it risks weakening the trust and incentives on which FOSS depends. Early Chardet 7.x development and evaluation also incorporated files originating from charset-normalizer's test corpus. Results measured on data that influenced implementation or model development are not independent validation. Charset-normalizer has been MIT-licensed since inception and originates from a continuous human-designed, encoding-agnostic project history. AI assistance may be used, but every proposed change remains subject to maintainer review, adjustment, testing, and accountability; AI is an engineering aid, not a mechanism for erasing provenance or project lineage. An attentive eye will see that some aspects lead by us are magically found in Chardet. + +## ⚡ Performance + +This package offer similar performances in general against Chardet.

We ensure that we offer the best (reasonable) BC result possible. + +See the docs for advanced usage : [readthedocs.io](https://charset-normalizer.readthedocs.io/en/latest/) + +## 😇 Why + +When I started using Chardet, I noticed that it was not suited to my expectations, and I wanted to propose a +reliable alternative using a completely different method. Also! I never back down on a good challenge! + +I **don't care** about the **originating charset** encoding, because **two different tables** can +produce **two identical rendered string.** +What I want is to get readable text, the best I can. + +In a way, **I'm brute forcing text decoding.** How cool is that ? 😎 + +Don't confuse package **ftfy** with charset-normalizer or chardet. ftfy goal is to repair Unicode string whereas charset-normalizer to convert raw file in unknown encoding to unicode. + +## 🍰 How + + - Discard all charset encoding table that could not fit the binary content. + - Measure noise, or the mess once opened (by chunks) with a corresponding charset encoding. + - Extract matches with the lowest mess detected. + - Additionally, we measure coherence / probe for a language. + +**Wait a minute**, what is noise/mess and coherence according to **YOU ?** + +*Noise :* I opened hundred of text files, **written by humans**, with the wrong encoding table. **I observed**, then +**I established** some ground rules about **what is obvious** when **it seems like** a mess (aka. defining noise in rendered text). + I know that my interpretation of what is noise is probably incomplete, feel free to contribute in order to + improve or rewrite it. + +*Coherence :* For each language there is on earth, we have computed ranked letter appearance occurrences (the best we can). So I thought +that intel is worth something here. So I use those records against decoded text to check if I can detect intelligent design. + +## ⚡ Known limitations + + - Language detection is unreliable when text contains two or more languages sharing identical letters. (eg. HTML (english tags) + Turkish content (Sharing Latin characters)) + - Every charset detector heavily depends on sufficient content. In common cases, do not bother run detection on very tiny content. + +## ⚠️ About Python EOLs + +**If you are running:** + +- Python >=2.7,<3.5: Unsupported +- Python 3.5: charset-normalizer < 2.1 +- Python 3.6: charset-normalizer < 3.1 + +Upgrade your Python interpreter as soon as possible. + +## 👤 Contributing + +Contributions, issues and feature requests are very much welcome.

It supports almost all record types. It +can be used for queries, zone transfers, and dynamic updates. It supports +TSIG-authenticated messages and EDNS0. + +`dnspython` provides both high- and low-level access to DNS. The high-level +classes perform queries for data of a given name, type, and class, and return an +answer set. The low-level classes allow direct manipulation of DNS zones, +messages, names, and records. + +To see a few of the ways `dnspython` can be used, look in the `examples/` +directory. + +`dnspython` is a utility to work with DNS, `/etc/hosts` is thus not used. For +simple forward DNS lookups, it's better to use `socket.getaddrinfo()` or +`socket.gethostbyname()`. + +`dnspython` originated at Nominum where it was developed to facilitate the +testing of DNS software. + +## ABOUT THIS RELEASE + +This is of `dnspython` 2.8.0. +Please read +[What's New](https://dnspython.readthedocs.io/en/stable/whatsnew.html) for +information about the changes in this release. + +## INSTALLATION + +* Many distributions have dnspython packaged for you, so you should check there + first. +* To use a wheel downloaded from PyPi, run: + +``` + pip install dnspython +``` + +* To install from the source code, go into the top-level of the source code + and run: + +``` + pip install --upgrade pip build + python -m build + pip install dist/*.whl +``` + +* To install the latest from the main branch, run +`pip install git+https://github.com/rthalley/dnspython.git` + +`dnspython`'s default installation does not depend on any modules other than +those in the Python standard library. To use some features, additional modules +must be installed. For convenience, `pip` options are defined for the +requirements. + +If you want to use DNS-over-HTTPS, run +`pip install dnspython[doh]`. + +If you want to use DNSSEC functionality, run +`pip install dnspython[dnssec]`. + +If you want to use internationalized domain names (IDNA) +functionality, you must run +`pip install dnspython[idna]` + +If you want to use the Trio asynchronous I/O package, run +`pip install dnspython[trio]`. + +If you want to use WMI on Windows to determine the active DNS settings +instead of the default registry scanning method, run +`pip install dnspython[wmi]`. + +If you want to try the experimental DNS-over-QUIC code, run +`pip install dnspython[doq]`. + +Note that you can install any combination of the above, e.g.: +`pip install dnspython[doh,dnssec,idna]` + +### Notices + +Python 2.x support ended with the release of 1.16.0. `dnspython` supports Python 3.10 +and later. Future support is aligned with the lifetime of the Python 3 versions. + +Documentation has moved to +[dnspython.readthedocs.io](https://dnspython.readthedocs.io). diff --git

With this library, you can quickly create key pairs (signing +key and verifying key), sign messages, and verify the signatures. You can +also agree on a shared secret key based on exchanged public keys. +The keys and signatures are very short, making them easy to handle and +incorporate into other protocols. + +**NOTE: This library should not be used in production settings, see [Security](#Security) for more details.** + +## Features + +This library provides key generation, signing, verifying, and shared secret +derivation for five +popular NIST "Suite B" GF(p) (_prime field_) curves, with key lengths of 192, +224, 256, 384, and 521 bits. The "short names" for these curves, as known by +the OpenSSL tool (`openssl ecparam -list_curves`), are: `prime192v1`, +`secp224r1`, `prime256v1`, `secp384r1`, and `secp521r1`. It includes the +256-bit curve `secp256k1` used by Bitcoin. There is also support for the +regular (non-twisted) variants of Brainpool curves from 160 to 512 bits. The +"short names" of those curves are: `brainpoolP160r1`, `brainpoolP192r1`, +`brainpoolP224r1`, `brainpoolP256r1`, `brainpoolP320r1`, `brainpoolP384r1`, +`brainpoolP512r1`. Few of the small curves from SEC standard are also +included (mainly to speed-up testing of the library), those are: +`secp112r1`, `secp112r2`, `secp128r1`, and `secp160r1`. +Key generation, siging and verifying is also supported for Ed25519 and +Ed448 curves. +No other curves are included, but it is not too hard to add support for more +curves over prime fields. + +## Dependencies + +This library uses only Python and the 'six' package. It is compatible with +Python 2.6, 2.7, and 3.6+. It also supports execution on alternative +implementations like pypy and pypy3. + +If `gmpy2` or `gmpy` is installed, they will be used for faster arithmetic. +Either of them can be installed after this library is installed, +`python-ecdsa` will detect their presence on start-up and use them +automatically. +You should prefer `gmpy2` on Python3 for optimal performance. + +To run the OpenSSL compatibility tests, the 'openssl' tool must be in your +`PATH`. This release has been tested successfully against OpenSSL 0.9.8o, +1.0.0a, 1.0.2f, 1.1.1d and 3.0.1 (among others). + + +## Installation + +This library is available on PyPI, it's recommended to install it using `pip`: + +``` +pip install ecdsa +``` + +In case higher performance is wanted and using native code is not a problem, +it's possible to specify installation together with `gmpy2`: + +``` +pip install ecdsa[gmpy2] +``` + +or (slower, legacy option): +``` +pip install ecdsa[gmpy] +``` + +## Speed + +The following table shows how long this library takes to generate key pairs +(`keygen`), to sign data (`sign`), to verify those signatures (`verify`), +to derive a shared secret (`ecdh`), and +to verify the signatures with no key-specific precomputation (`no PC verify`). +All those values are in seconds. +For convenience, the inverses of those values are also provided: +how many keys per second can be generated (`keygen/s`), how many signatures +can be made per second (`sign/s`), how many signatures can be verified +per second (`verify/s`), how many shared secrets can be derived per second +(`ecdh/s`), and how many signatures with no key specific +precomputation can be verified per second (`no PC verify/s`). The size of raw +signature (generally the smallest +the way a signature can be encoded) is also provided in the `siglen` column. +Use `tox -e speed` to generate this table on your own computer. +On an

his [download site][2]. In 2010, +Brian Warner wrote a wrapper around this code, to make it a bit easier and +safer to use. In 2020, Hubert Kario included an implementation of elliptic +curve cryptography that uses Jacobian coordinates internally, improving +performance about 20-fold. You are looking at the README for this wrapper. + +[1]: http://www.derkeiler.com/Newsgroups/sci.crypt/2006-01/msg00651.html +[2]: http://webpages.charter.net/curryfans/peter/downloads.html + +## Testing + +To run the full test suite, do this: + + tox -e coverage + +On an Intel Core i7 4790K @ 4.0GHz, the tests take about 18 seconds to execute. +The test suite uses +[`hypothesis`](https://github.com/HypothesisWorks/hypothesis) so there is some +inherent variability in the test suite execution time. + +One part of `test_pyecdsa.py` and `test_ecdh.py` checks compatibility with +OpenSSL, by running the "openssl" CLI tool, make sure it's in your `PATH` if +you want to test compatibility with it (if OpenSSL is missing, too old, or +doesn't support all the curves supported in upstream releases you will see +skipped tests in the above `coverage` run). + +## Security + +This library was not designed with security in mind. If you are processing +data that needs to be protected we suggest you use a quality wrapper around +OpenSSL. [pyca/cryptography](https://cryptography.io) is one example of such +a wrapper. The primary use-case of this library is as a portable library for +interoperability testing and as a teaching tool. + +**This library does not protect against side-channel attacks.** + +Do not allow attackers to measure how long it takes you to generate a key pair +or sign a message. Do not allow attackers to run code on the same physical +machine when key pair generation or signing is taking place (this includes +virtual machines). Do not allow attackers to measure how much power your +computer uses while generating the key pair or signing a message. Do not allow +attackers to measure RF interference coming from your computer while generating +a key pair or signing a message. Note: just loading the private key will cause +key pair generation. Other operations or attack vectors may also be +vulnerable to attacks. **For a sophisticated attacker observing just one +operation with a private key will be sufficient to completely +reconstruct the private key**. + +Please also note that any Pure-python cryptographic library will be vulnerable +to the same side-channel attacks. This is because Python does not provide +side-channel secure primitives (with the exception of +[`hmac.compare_digest()`][3]), making side-channel secure programming +impossible. + +This library depends upon a strong source of random numbers. Do not use it on +a system where `os.urandom()` does not provide cryptographically secure +random numbers. + +[3]: https://docs.python.org/3/library/hmac.html#hmac.compare_digest + +## Usage + +You start by creating a `SigningKey`. You can use this to sign data, by passing +in data as a byte string and getting back the signature (also a byte string). +You can also ask a `SigningKey` to give you the corresponding `VerifyingKey`. +The `VerifyingKey` can be used to verify a signature, by passing it both the +data string and the signature byte string: it either returns True or raises +`BadSignatureError`. + +```python +from ecdsa import SigningKey +sk = SigningKey.generate() # uses NIST192p +vk = sk.verifying_key +signature = sk.sign(b"message") +assert vk.verify(signature, b"message") +``` + +Each `SigningKey`/`VerifyingKey` is associated with a specific curve, like +NIST192p (the default one). Longer curves are more secure, but take longer to +use, and result in longer keys and signatures. + +```python +from ecdsa import SigningKey, NIST384p +sk = SigningKey.generate(curve=NIST384p) +vk = sk.verifying_key +signature = sk.sign(b"message") +assert vk.verify(signature, b"message") +``` + +The `SigningKey` can be serialized into several different formats: the shortest +is to call `s=sk.to_string()`, and then re-create it with +`SigningKey.from_string(s, curve)` . This short form does not record the +curve, so you must be sure to pass to `from_string()` the same curve you used +for the original key. The short form of a NIST192p-based signing key is just 24 +bytes long. If a point encoding is invalid or it does not lie on the specified +curve, `from_string()` will raise `MalformedPointError`. + +```python +from ecdsa import SigningKey, NIST384p +sk = SigningKey.generate(curve=NIST384p) +sk_string = sk.to_string() +sk2 = SigningKey.from_string(sk_string, curve=NIST384p) +print(sk_string.hex()) +print(sk2.to_string().hex()) +``` + +Note: while the methods are called `to_string()` the type they return is +actually `bytes`, the "string" part is leftover from Python 2. + +`sk.to_pem()` and `sk.to_der()` will serialize the signing key into the same +formats that OpenSSL uses. The PEM file looks like the familiar ASCII-armored +`"-----BEGIN EC PRIVATE KEY-----"` base64-encoded format, and the DER format +is a shorter binary form of the same data. +`SigningKey.from_pem()/.from_der()` will undo this serialization. These +formats include the curve name, so you do not need to pass in a curve +identifier to the deserializer. In case the file is malformed `from_der()` +and `from_pem()` will raise `UnexpectedDER` or` MalformedPointError`. + +```python +from ecdsa import SigningKey, NIST384p +sk = SigningKey.generate(curve=NIST384p) +sk_pem = sk.to_pem() +sk2 = SigningKey.from_pem(sk_pem) +# sk and sk2 are the same key +``` + +Likewise, the `VerifyingKey` can be serialized in the same way: +`vk.to_string()/VerifyingKey.from_string()`, `to_pem()/from_pem()`, and +`to_der()/from_der()`. The same `curve=` argument is needed for +`VerifyingKey.from_string()`. + +```python +from ecdsa import SigningKey, VerifyingKey, NIST384p +sk = SigningKey.generate(curve=NIST384p) +vk = sk.verifying_key +vk_string = vk.to_string() +vk2 = VerifyingKey.from_string(vk_string, curve=NIST384p) +# vk and vk2 are the same key + +from ecdsa import SigningKey, VerifyingKey, NIST384p +sk = SigningKey.generate(curve=NIST384p) +vk = sk.verifying_key +vk_pem = vk.to_pem() +vk2 = VerifyingKey.from_pem(vk_pem) +# vk and vk2 are the same key +``` + +There are a couple of different ways to compute a signature. Fundamentally, +ECDSA takes a number that represents the data being signed, and returns a +pair of numbers that represent the signature. The `hashfunc=` argument to +`sk.sign()` and `vk.verify()` is used to turn an arbitrary string into a +fixed-length digest, which is then turned into a number that ECDSA can sign, +and both sign and verify must use the same approach. The default value is +`hashlib.sha1`, but if you use NIST256p or a longer curve, you can use +`hashlib.sha256` instead. + +There are also multiple ways to represent a signature. The default +`sk.sign()` and `vk.verify()` methods present it as a short string, for +simplicity and minimal overhead. To use a different scheme, use the +`sk.sign(sigencode=)` and `vk.verify(sigdecode=)` arguments. There are helper +functions in the `ecdsa.util` module that can be useful here. + +It is also possible to create a `SigningKey` from a "seed", which is +deterministic. This can be used in protocols where you want to derive +consistent signing keys from some other secret, for example when you want +three separate keys and only want to store a single master secret. You should +start with a uniformly-distributed unguessable seed with about `curve.baselen` +bytes of entropy, and then use one of the helper functions in `ecdsa.util` to +convert it into an integer in the correct range, and then finally pass it +into `SigningKey.from_secret_exponent()`, like this: + +```python +import os +from ecdsa import NIST384p, SigningKey +from ecdsa.util import randrange_from_seed__trytryagain + +def make_key(seed): + secexp = randrange_from_seed__trytryagain(seed, NIST384p.order) + return SigningKey.from_secret_exponent(secexp, curve=NIST384p) + +seed = os.urandom(NIST384p.baselen) # or other starting point +sk1a = make_key(seed) +sk1b = make_key(seed) +# note: sk1a and sk1b are the same key +assert sk1a.to_string() == sk1b.to_string() +sk2 = make_key(b"2-"+seed) # different key +assert sk1a.to_string() != sk2.to_string() +``` + +In case the application will verify a lot of signatures made with a single +key, it's possible to precompute some of the internal values to make +signature verification significantly faster. The break-even point occurs at +about 100 signatures verified. + +To perform precomputation, you can call the `precompute()` method +on `VerifyingKey` instance: +```python +from ecdsa import SigningKey, NIST384p +sk = SigningKey.generate(curve=NIST384p) +vk = sk.verifying_key +vk.precompute() +signature = sk.sign(b"message") +assert vk.verify(signature, b"message") +``` + +Once `precompute()` was called, all signature verifications with this key will +be faster to execute. + +## OpenSSL Compatibility + +To produce signatures that can be verified by OpenSSL tools, or to verify +signatures that were produced by those tools, use: + +```python +# openssl ecparam -name prime256v1 -genkey -out sk.pem +# openssl ec -in sk.pem -pubout -out vk.pem +# echo "data for signing" > data +# openssl dgst -sha256 -sign sk.pem -out data.sig data +# openssl dgst -sha256 -verify vk.pem -signature data.sig data +# openssl dgst -sha256 -prverify sk.pem -signature data.sig data + +import hashlib +from ecdsa import SigningKey, VerifyingKey +from ecdsa.util import sigencode_der, sigdecode_der + +with open("vk.pem") as f: + vk = VerifyingKey.from_pem(f.read()) + +with open("data", "rb") as f: + data = f.read() + +with open("data.sig", "rb") as f: + signature = f.read() + +assert vk.verify(signature, data, hashlib.sha256, sigdecode=sigdecode_der) + +with open("sk.pem") as f: + sk = SigningKey.from_pem(f.read(), hashlib.sha256) + +new_signature = sk.sign_deterministic(data, sigencode=sigencode_der) + +with open("data.sig2", "wb") as f: + f.write(new_signature) + +# openssl dgst -sha256 -verify vk.pem -signature data.sig2 data +``` + +Note: if compatibility with OpenSSL 1.0.0 or earlier is necessary, the +`sigencode_string` and `sigdecode_string` from `ecdsa.util` can be used for +respectively writing and reading the signatures. + +The keys also can be written in format that openssl can handle: + +```python +from ecdsa import SigningKey, VerifyingKey + +with open("sk.pem") as f: + sk = SigningKey.from_pem(f.read()) +with open("sk.pem", "wb") as f: + f.write(sk.to_pem()) + +with open("vk.pem") as f: + vk = VerifyingKey.from_pem(f.read()) +with open("vk.pem", "wb") as f: + f.write(vk.to_pem()) +``` + +## Entropy + +Creating a signing key with `SigningKey.generate()` requires some form of +entropy (as opposed to +`from_secret_exponent`/`from_string`/`from_der`/`from_pem`, +which are deterministic and do not require an entropy source). The default +source is `os.urandom()`, but you can pass any other function that behaves +like `os.urandom` as the `entropy=` argument to do something different. This +may be useful in unit tests, where you want to achieve repeatable results. The +`ecdsa.util.PRNG` utility is handy here: it takes a seed and produces a strong +pseudo-random stream from it: + +```python +from ecdsa.util import PRNG +from ecdsa import SigningKey +rng1 = PRNG(b"seed") +sk1 = SigningKey.generate(entropy=rng1) +rng2 = PRNG(b"seed") +sk2 = SigningKey.generate(entropy=rng2) +# sk1 and sk2 are the same key +``` + +Likewise, ECDSA signature generation requires a random number, and each +signature must use a different one (using the same number twice will +immediately reveal the private signing key). The `sk.sign()` method takes an +`entropy=` argument which behaves the same as `SigningKey.generate(entropy=)`. + +## Deterministic Signatures + +If you call `SigningKey.sign_deterministic(data)` instead of `.sign(data)`, +the code will generate a deterministic signature instead of a random one. +This uses the algorithm from RFC6979 to safely generate a unique `k` value, +derived from the private key and the message being signed. Each time you sign +the same message with the same key, you will get the same signature (using +the same `k`). + +This may become the default in a future version, as it is not vulnerable to +failures of the entropy source. + +## Examples + +Create a NIST192p key pair and immediately save both to disk: + +```python +from ecdsa import SigningKey +sk = SigningKey.generate() +vk = sk.verifying_key +with open("private.pem", "wb") as f: + f.write(sk.to_pem()) +with open("public.pem", "wb") as f: + f.write(vk.to_pem()) +``` + +Load a signing key from disk, use it to sign a message (using SHA-1), and write +the signature to disk: + +```python +from ecdsa import SigningKey +with open("private.pem") as f: + sk = SigningKey.from_pem(f.read()) +with open("message", "rb") as f: + message = f.read() +sig = sk.sign(message) +with open("signature", "wb") as f: + f.write(sig) +``` + +Load the verifying key, message, and signature from disk, and verify the +signature (assume SHA-1 hash): + +```python +from ecdsa import VerifyingKey, BadSignatureError +vk = VerifyingKey.from_pem(open("public.pem").read()) +with open("message", "rb") as f: + message = f.read() +with open("signature", "rb") as f: + sig = f.read() +try: + vk.verify(sig, message) + print "good signature" +except BadSignatureError: + print "BAD SIGNATURE" +``` + +Create a NIST521p key pair: + +```python +from ecdsa import SigningKey, NIST521p +sk = SigningKey.generate(curve=NIST521p) +vk = sk.verifying_key +``` + +Create three independent signing keys from a master seed: + +```python +from ecdsa import NIST192p, SigningKey +from ecdsa.util import randrange_from_seed__trytryagain + +def make_key_from_seed(seed, curve=NIST192p): + secexp = randrange_from_seed__trytryagain(seed, curve.order) + return SigningKey.from_secret_exponent(secexp, curve) + +sk1 = make_key_from_seed("1:%s" % seed) +sk2 = make_key_from_seed("2:%s" % seed) +sk3 = make_key_from_seed("3:%s" % seed) +``` + +Load a verifying key from disk and print it using hex encoding in +uncompressed and compressed format (defined in X9.62 and SEC1 standards): + +```python +from ecdsa import VerifyingKey + +with open("public.pem") as f: +

Turn on check_deliverability + # for first-time validations like on account creation pages (but not + # login pages). + emailinfo = validate_email(email, check_deliverability=False) + + # After this point, use only the normalized form of the email address, + # especially before going to a database query. + email = emailinfo.normalized + +except EmailNotValidError as e: + + # The exception message is human-readable explanation of why it's + # not a valid (or deliverable) email address. + print(str(e)) +``` + +This validates the address and gives you its normalized form. You should +**put the normalized form in your database** and always normalize before +checking if an address is in your database. When using this in a login form, +set `check_deliverability` to `False` to avoid unnecessary DNS queries. + +Usage +----- + +### Overview + +The module provides a function `validate_email(email_address)` which +takes an email address and: + +- Raises a `EmailNotValidError` with a helpful, human-readable error + message explaining why the email address is not valid, or +- Returns an object with a normalized form of the email address (which + you should use!) and other information about it. + +When an email address is not valid, `validate_email` raises either an +`EmailSyntaxError` if the form of the address is invalid or an +`EmailUndeliverableError` if the domain name fails DNS checks. Both +exception classes are subclasses of `EmailNotValidError`, which in turn +is a subclass of `ValueError`. + +But when an email address is valid, an object is returned containing +a normalized form of the email address (which you should use!) and +other information. + +The validator doesn't, by default, permit obsoleted forms of email addresses +that no one uses anymore even though they are still valid and deliverable, since +they will probably give you grief if you're using email for login. (See +later in the document about how to allow some obsolete forms.) + +The validator optionally checks that the domain name in the email address has +a DNS MX record indicating that it can receive email. (Except a Null MX record. +If there is no MX record, a fallback A/AAAA-record is permitted, unless +a reject-all SPF record is present.) DNS is slow and sometimes unavailable or +unreliable, so consider whether these checks are useful for your use case and +turn them off if they aren't. +There is nothing to be gained by trying to actually contact an SMTP server, so +that's not done here. For privacy, security, and practicality reasons, servers +are good at not giving away whether an address is +deliverable or not: email addresses that appear to accept mail at first +can bounce mail after a delay, and bounced mail may indicate a temporary +failure of a good email address (sometimes an intentional failure, like +greylisting). + +### Options + +The `validate_email` function also accepts the following keyword arguments +(defaults are as shown below): + +`check_deliverability=True`: If true, DNS queries are made to check that the domain name in the email address (the part after the @-sign) can receive mail, as described above. Set to `False` to skip this DNS-based check. It is recommended to pass `False` when performing validation for login pages (but not account creation pages) since re-validation of a previously validated domain in your database by querying DNS at every login is probably undesirable. You can also set `email_validator.CHECK_DELIVERABILITY` to `False` to turn this off for all calls by default. + +`dns_resolver=None`: Pass an instance of [dns.resolver.Resolver](https://dnspython.readthedocs.io/en/latest/resolver-class.html) to control the DNS resolver including setting a timeout and [a cache](https://dnspython.readthedocs.io/en/latest/resolver-caching.html). The `caching_resolver` function shown below is a helper function to construct a dns.resolver.Resolver with a [LRUCache](https://dnspython.readthedocs.io/en/latest/resolver-caching.html#dns.resolver.LRUCache). Reuse the same resolver instance across calls to `validate_email` to make use of the cache. + +`test_environment=False`: If `True`, DNS-based deliverability checks are disabled and `test` and `**.test` domain names are permitted (see below). You can also set `email_validator.TEST_ENVIRONMENT` to `True` to turn it on for all calls by default. + +`allow_smtputf8=True`: Set to `False` to prohibit internationalized addresses that would + require the + [SMTPUTF8](https://tools.ietf.org/html/rfc6531) extension. You can also set `email_validator.ALLOW_SMTPUTF8` to `False` to turn it off for all calls by default. + +`allow_quoted_local=False`: Set to `True` to allow obscure and potentially problematic email addresses in which the part of the address before the @-sign contains spaces, @-signs, or other surprising characters when the local part is surrounded in quotes (so-called quoted-string local parts). In the object returned by `validate_email`, the normalized local part removes any unnecessary backslash-escaping and even removes the surrounding quotes if the address would be valid without them. You can also set `email_validator.ALLOW_QUOTED_LOCAL` to `True` to turn this on for all calls by default. + +`allow_domain_literal=False`: Set to `True` to allow bracketed IPv4 and "IPv6:"-prefixd IPv6 addresses in the domain part of the email address. No deliverability checks are performed for these addresses. In the object returned by `validate_email`, the normalized domain will use the condensed IPv6 format, if applicable. The object's `domain_address` attribute will hold the parsed `ipaddress.IPv4Address` or `ipaddress.IPv6Address` object if applicable. You can also set `email_validator.ALLOW_DOMAIN_LITERAL` to `True` to turn this on for all calls by default. + +`allow_display_name=False`: Set to `True` to allow a display name and bracketed address in the input string, like `My Name `. It's implemented in the spirit but not the letter of RFC 5322 3.4, so it may be stricter or more relaxed than what you want. The display name, if present, is provided in the returned object's `display_name` field after being unquoted and unescaped. You can also set `email_validator.ALLOW_DISPLAY_NAME` to `True` to turn this on for all calls by default. + +`allow_empty_local=False`: Set to `True` to allow an empty local part (i.e. + `@example.com`), e.g. for validating Postfix aliases. + + +### DNS timeout and cache + +When validating many email addresses or to control the timeout (the default is 15 seconds), create a caching [dns.resolver.Resolver](https://dnspython.readthedocs.io/en/latest/resolver-class.html) to reuse in each call. The `caching_resolver` function returns one easily for you: + +```python +from email_validator import validate_email, caching_resolver + +resolver = caching_resolver(timeout=10) + +while True: + validate_email(email, dns_resolver=resolver) +``` + +### Test addresses + +This library rejects email addresses that use the [Special Use Domain Names](https://www.iana.org/assignments/special-use-domain-names/special-use-domain-names.xhtml) `invalid`, `localhost`, `test`, and some others by raising `EmailSyntaxError`. This is to protect your system from abuse: You probably don't want a user to be able to cause an email to be sent to `localhost` (although they might be able to still do so via a malicious MX record). However, in your non-production test environments you may want to use `@test` or `@myname.test` email addresses. There are three ways you can allow this: + +1. Add `test_environment=True` to the call to `validate_email` (see above). +2. Set `email_validator.TEST_ENVIRONMENT` to `True` globally. +3. Remove the special-use domain name that you want to use from `email_validator.SPECIAL_USE_DOMAIN_NAMES`, e.g.: + +```python +import email_validator +email_validator.SPECIAL_USE_DOMAIN_NAMES.remove("test") +``` + +It is tempting to use `@example.com/net/org` in tests. They are *not* in this library's `SPECIAL_USE_DOMAIN_NAMES` list so you can, but shouldn't, use them. These domains are reserved to IANA for use in documentation so there is no risk of accidentally emailing someone at those domains. But beware that this library will nevertheless reject these domain names if DNS-based deliverability checks are not disabled because these domains do not resolve to domains that accept email. In tests, consider using your own domain name or `@test` or `@myname.test` instead. + +Internationalized email addresses +--------------------------------- + +The email protocol SMTP and the domain name system DNS have historically +only allowed English (ASCII) characters in email addresses and domain names, +respectively. Each has adapted to internationalization in a separate +way, creating two separate aspects to email address internationalization. + +(If your mail submission library doesn't support Unicode at all, then +immediately prior to mail submission you must replace the email address with +its ASCII-ized form. This library gives you back the ASCII-ized form in the +`ascii_email` field in the returned object.) + +### Internationalized domain names (IDN) + +The first is [internationalized domain names (RFC +5891)](https://tools.ietf.org/html/rfc5891), a.k.a IDNA 2008. The DNS +system has not been updated with Unicode support. Instead, internationalized +domain names are converted into a special IDNA ASCII "[Punycode](https://www.rfc-editor.org/rfc/rfc3492.txt)" +form starting with `xn--`. When an email address has non-ASCII +characters in its domain part, the domain part is replaced with its IDNA +ASCII equivalent form in the process of mail transmission. Your mail +submission library probably does this for you transparently. ([Compliance +around the web is not very good though](http://archives.miloush.net/michkap/archive/2012/02/27/10273315.html).) This library conforms to IDNA 2008 +using the [idna](https://github.com/kjd/idna) module by Kim Davies. + +### Internationalized local parts + +The second sort of internationalization is internationalization in the +*local* part of the address (before the @-sign). In non-internationalized +email addresses, only English letters, numbers, and some punctuation +(`._!#$%&'^``*+-=~/?{|}`) are allowed. In internationalized email address +local parts, a wider range of Unicode characters are allowed. + +Email addresses with these non-ASCII characters require that your mail +submission library and all the mail servers along the route to the destination, +including your own outbound mail server, all support the +[SMTPUTF8 (RFC 6531)](https://tools.ietf.org/html/rfc6531) extension. +Support for SMTPUTF8 varies. If you know ahead of time that SMTPUTF8 is not +supported by your mail submission stack, then you must filter out addresses that +require SMTPUTF8 using the `allow_smtputf8=False` keyword argument (see above). +This will cause the validation function to raise a `EmailSyntaxError` if +delivery would require SMTPUTF8. If you do not set `allow_smtputf8=False`, +you can also check the value of the `smtputf8` field in the returned object. + +### Unsafe Unicode characters are rejected + +A surprisingly large number of Unicode characters are not safe to display, +especially when the email address is concatenated with other text, so this +library tries to protect you by not permitting reserved, non-, private use, +formatting (which can be used to alter the display order of characters), +whitespace, and control characters, and combining characters +as the first character of the local part and the domain name (so that they +cannot combine with something outside of the email address string or with +the @-sign). See https://qntm.org/safe and https://trojansource.codes/ +for relevant prior work. (Other than whitespace, these are checks that +you should be applying to nearly all user inputs in a security-sensitive +context.) This does not guard against the well known problem that many +Unicode characters look alike, which can be used to fool humans reading +displayed text. + + +Normalization +------------- + +### Unicode Normalization + +The use of Unicode in email addresses introduced a normalization +problem. Different Unicode strings can look identical and have the same +semantic meaning to the user. The `normalized` field returned on successful +validation provides the correctly normalized form of the given email +address. + +For example, the CJK fullwidth Latin letters are considered semantically +equivalent in domain names to their ASCII counterparts. This library +normalizes them to their ASCII counterparts (as required by IDNA): + +```python +emailinfo = validate_email("me@Ｄｏｍａｉｎ.com") +print(emailinfo.normalized) +print(emailinfo.ascii_email) +# prints "me@domain.com" twice +``` + +Because an end-user might type their email address in different (but +equivalent) un-normalized forms at different times, you ought to +replace what they enter with the normalized form immediately prior to +going into your database (during account creation), querying your database +(during login), or sending outbound mail. + +The normalizations include lowercasing the domain part of the email +address (domain names are case-insensitive), [Unicode "NFC" +normalization](https://en.wikipedia.org/wiki/Unicode_equivalence) of the +whole address (which turns characters plus [combining +characters](https://en.wikipedia.org/wiki/Combining_character) into +precomposed characters where possible, replacement of [fullwidth and +halfwidth +characters](https://en.wikipedia.org/wiki/Halfwidth_and_fullwidth_forms) +in the domain part, possibly other +[UTS46](http://unicode.org/reports/tr46) mappings on the domain part, +and conversion from Punycode to Unicode characters. + +Normalization may change the characters in the email address and the +length of the email address, such that a string might be a valid address +before normalization but invalid after, or vice versa. This library only +permits addresses that are valid both before and after normalization. + +(See [RFC 6532 (internationalized email) section +3.1](https://tools.ietf.org/html/rfc6532#section-3.1) and [RFC 5895 +(IDNA 2008) section 2](http://www.ietf.org/rfc/rfc5895.txt).) + +### Other Normalization + +Normalization is also applied to quoted-string local parts and domain +literal IPv6 addresses if you have allowed them by the `allow_quoted_local` +and `allow_domain_literal` options. In quoted-string local parts, unnecessary +backslash escaping is removed and even the surrounding quotes are removed if +they are unnecessary. For IPv6 domain literals, the IPv6 address is +normalized to condensed form. [RFC 2142](https://datatracker.ietf.org/doc/html/rfc2142) +also requires lowercase normalization for some specific mailbox names like `postmaster@`. + + +Examples +-------- + +For the email address `test@joshdata.me`, the returned object is: + +```python +ValidatedEmail( + normalized='test@joshdata.me', + local_part='test', + domain='joshdata.me', + ascii_email='test@joshdata.me', + ascii_local_part='test', + ascii_domain='joshdata.me', + smtputf8=False) +``` + +For the fictitious but valid address `example@ツ.ⓁⒾⒻⒺ`, which has an +internationalized domain but ASCII local part, the returned object is: + +```python +ValidatedEmail( + normalized='example@ツ.life', + local_part='example', + domain='ツ.life', + ascii_email='example@xn--bdk.life', + ascii_local_part='example', + ascii_domain='xn--bdk.life', + smtputf8=False) + +``` + +Note that `normalized` and other fields provide a normalized form of the +email address, domain name, and (in other cases) local part (see earlier +discussion of normalization), which you should use in your database. + +Calling `validate_email` with the ASCII form of the above email address, +`example@xn--bdk.life`, returns the exact same information (i.e., the +`normalized` field always will contain Unicode characters, not Punycode). + +For the fictitious address `ツ-test@joshdata.me`, which has an +internationalized local part, the returned object is: + +```python +ValidatedEmail( + normalized='ツ-test@joshdata.me', + local_part='ツ-test', + domain='joshdata.me', + ascii_email=None, + ascii_local_part=None, + ascii_domain='joshdata.me', + smtputf8=True) +``` + +Now `smtputf8` is `True` and `ascii_email` is `None` because the local +part of the address is internationalized. The `local_part` and `normalized` fields +return the normalized form of the address. + +Return value +------------ + +When an email address passes validation, the fields in the returned object +are: + +| Field | Value | +| -----:|-------| +| `normalized` | The normalized form of the email address that you should put in your database. This combines the `local_part` and `domain` fields (see below). | +| `ascii_email` | If set, an ASCII-only form of the normalized email address by replacing the domain part with [IDNA](https://tools.ietf.org/html/rfc5891) [Punycode](https://www.rfc-editor.org/rfc/rfc3492.txt). This field will be present when an ASCII-only form of the email address exists (including if the email address is already ASCII). If the local part of the email address contains internationalized characters, `ascii_email` will be `None`. If set, it merely combines `ascii_local_part` and `ascii_domain`. | +| `local_part` | The normalized local part of the given email address (before the @-sign). Normalization includes Unicode NFC normalization and removing unnecessary quoted-string quotes and backslashes. If `allow_quoted_local` is True and the surrounding quotes are necessary, the quotes _will_ be present in this field. | +| `ascii_local_part` | If set, the local part, which is composed of ASCII characters only. | +| `domain` | The canonical internationalized Unicode form of the domain part of the email address. If the returned string contains non-ASCII characters, either the [SMTPUTF8](https://tools.ietf.org/html/rfc6531) feature of your mail relay will be required to transmit the message or else the email address's domain part must be converted to IDNA ASCII first: Use `ascii_domain` field instead. | +| `ascii_domain` | The [IDNA](https://tools.ietf.org/html/rfc5891) [Punycode](https://www.rfc-editor.org/rfc/rfc3492.txt)-encoded form of the domain part of the given email address, as it would be transmitted on the wire. | +| `domain_address` | If domain literals are allowed and if the email address contains one, an `ipaddress.IPv4Address` or `ipaddress.IPv6Address` object. | +| `display_name` | If no display name was present and angle brackets do not surround the address, this will be `None`; otherwise, it will be set to the display name, or the empty string if there were angle brackets but no display name. If the display name was quoted, it will be unquoted and unescaped. | +| `smtputf8` | A boolean indicating that the [SMTPUTF8](https://tools.ietf.org/html/rfc6531) feature of your mail relay will be required to transmit messages to this address because the local part of the address has non-ASCII characters (the local part cannot be IDNA-encoded). If `allow_smtputf8=False` is passed as an argument, this flag will always be false because an exception is raised if it would have been true. | +| `mx` | A list of (priority, domain) tuples of MX records specified in the DNS for the domain (see [RFC 5321 section 5](https://tools.ietf.org/html/rfc5321#section-5)). May be `None` if the deliverability check could not be completed because of a temporary issue like a timeout. | +| `mx_fallback_type` | `None` if an `MX` record is found. If no MX records are actually specified in DNS and instead are inferred, through an obsolete mechanism, from A or AAAA records, the value is the type of DNS record used instead (`A` or `AAAA`). May be `None` if the deliverability check could not be completed because of a temporary issue like a timeout. | +| `spf` | Any SPF record found while checking deliverability. Only set if the SPF record is queried. | + +Assumptions +----------- + +By design, this validator does not pass all email addresses that +strictly conform to the standards. Many email address forms are obsolete +or likely to cause trouble: + +* The validator assumes the email address is intended to be + usable on the public Internet. The domain part + of the email address must be a resolvable domain name + (see the deliverability checks described above). + Most [Special Use Domain Names](https://www.iana.org/assignments/special-use-domain-names/special-use-domain-names.xhtml) + and their subdomains, as well as + domain names without a `.`, are rejected as a syntax error + (except see the `test_environment` parameter above). +* Obsolete email syntaxes are rejected: + The unusual ["(comment)" syntax](https://github.com/JoshData/python-email-validator/issues/77) + is rejected. Extremely old obsolete syntaxes are + rejected. Quoted-string local parts and domain-literal addresses + are rejected by default, but there are options to allow them (see above). + No one uses these forms anymore, and I can't think of any reason why anyone + using this library would need to accept them. + +Testing +------- + +Tests can be run using + +```sh +pip install -r test_requirements.txt +make test +``` + +Tests run with mocked DNS responses. When adding or changing tests, temporarily turn on the `BUILD_MOCKED_DNS_RESPONSE_DATA` flag in `tests/mocked_dns_responses.py` to re-build the database of mocked responses from live queries. + +For Project Maintainers +----------------------- + +The package is distributed as a universal wheel and as a source package. + +To release: + +* Update CHANGELOG.md. +* Update the version number in `email_validator/version.py`. +* Make & push a commit with the new version number and make sure tests pass. +* Make & push a tag (see command below). +* Make a release at https://github.com/JoshData/python-email-validator/releases/new. +* Publish a source and wheel distribution to pypi (see command below). + +```sh +git tag v$(cat email_validator/version.py | sed "s/.* = //" | sed 's/"//g') +git push --tags +./release_to_pypi.sh +``` + +License +------- + +This project is free of any copyright restrictions per the [Unlicense](https://unlicense.org/).

HISTORY OF THE SOFTWARE +========================== + +Python was created in the early 1990s by Guido van Rossum at Stichting +Mathematisch Centrum (CWI, see https://www.cwi.nl) in the Netherlands +as a successor of a language called ABC. Guido remains Python's +principal author, although it includes many contributions from others. + +In 1995, Guido continued his work on Python at the Corporation for +National Research Initiatives (CNRI, see https://www.cnri.reston.va.us) +in Reston, Virginia where he released several versions of the +software. + +In May 2000, Guido and the Python core development team moved to +BeOpen.com to form the BeOpen PythonLabs team. In October of the same +year, the PythonLabs team moved to Digital Creations, which became +Zope Corporation. In 2001, the Python Software Foundation (PSF, see +https://www.python.org/psf/) was formed, a non-profit organization +created specifically to own Python-related Intellectual Property. +Zope Corporation was a sponsoring member of the PSF. + +All Python releases are Open Source (see https://opensource.org for +the Open Source Definition). Historically, most, but not all, Python +releases have also been GPL-compatible; the table below summarizes +the various releases. + + Release Derived Year Owner GPL- + from compatible?

All Python licenses, unlike the GPL, let you distribute + a modified version without making your changes open source. The + GPL-compatible licenses make it possible to combine Python with + other software that is released under the GPL; the others don't. + +(2) According to Richard Stallman, 1.6.1 is not GPL-compatible, + because its license has a choice of law clause. According to + CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1 + is "not incompatible" with the GPL. + +Thanks to the many outside volunteers who have worked under Guido's +direction to make these releases possible. + + +B.

Once an element has been added to the tree, it is written to +the file or stream and the memory is then cleared. + +This module is based upon the `xmlfile module from lxml `_ with the aim of allowing code to be developed that will work with both libraries. +It was developed initially for the openpyxl project, but is now a standalone module. + +The code was written by Elias Rabel as part of the `Python Düsseldorf `_ openpyxl sprint in September 2014. + +Proper support for incremental writing was provided by Daniel Hillier in 2024 + +Note on performance +------------------- + +The code was not developed with performance in mind, but turned out to be faster than the existing SAX-based implementation but is generally slower than lxml's xmlfile. +There is one area where an optimisation for lxml may negatively affect the performance of et_xmfile and that is when using the `.element()` method on the xmlfile context manager. It is, therefore, recommended simply to create Elements write these directly, as in the sample code. diff --git a/venv/lib/python3.12/site-packages/et_xmlfile-2.0.0.dist-info/RECORD b/venv/lib/python3.12/site-packages/et_xmlfile-2.0.0.dist-info/RECORD new file mode 100644 index 0000000..036a078 --- /dev/null +++ b/venv/lib/python3.12/site-packages/et_xmlfile-2.0.0.dist-info/RECORD @@ -0,0 +1,14 @@ +et_xmlfile-2.0.0.dist-info/AUTHORS.txt,sha256=fwOAKepUY2Bd0ieNMACZo4G86ekN2oPMqyBCNGtsgQc,82 +et_xmlfile-2.0.0.dist-info/INSTALLER,sha256=zuuue4knoyJ-UwPPXg8fezS7VCrXJQrAP7zeNuwvFQg,4 +et_xmlfile-2.0.0.dist-info/LICENCE.python,sha256=TM2q68D0S4NyDsA5m7erMprc4GfdYvc8VTWi3AViirI,14688 +et_xmlfile-2.0.0.dist-info/LICENCE.rst,sha256=DIS7QvXTZ-Xr-fwt3jWxYUHfXuD9wYklCFi8bFVg9p4,1131 +et_xmlfile-2.0.0.dist-info/METADATA,sha256=DpfX6pCe0PvgPYi8i29YZ3zuGwe9M1PONhzSQFkVIE4,2711 +et_xmlfile-2.0.0.dist-info/RECORD,, +et_xmlfile-2.0.0.dist-info/WHEEL,sha256=HiCZjzuy6Dw0hdX5R3LCFPDmFS4BWl8H-8W39XfmgX4,91 +et_xmlfile-2.0.0.dist-info/top_level.txt,sha256=34-74d5NNARgTsPxCMta5o28XpBNmSN0iCZhtmx2Fk8,11 +et_xmlfile/__init__.py,sha256=AQ4_2cNUEyUHlHo-Y3Gd6-8S_6eyKd55jYO4eh23UHw,228 +et_xmlfile/__pycache__/__init__.cpython-312.pyc,, +et_xmlfile/__pycache__/incremental_tree.cpython-312.pyc,, +et_xmlfile/__pycache__/xmlfile.cpython-312.pyc,, +et_xmlfile/incremental_tree.py,sha256=lX4VStfzUNK0jtrVsvshPENu7E_zQirglkyRtzGDwEg,34534 +et_xmlfile/xmlfile.py,sha256=6QdxBq2P0Cf35R-oyXjLl5wOItfJJ4Yy6AlIF9RX7Bg,4886 diff --git a/venv/lib/python3.12/site-packages/et_xmlfile-2.0.0.dist-info/WHEEL b/venv/lib/python3.12/site-packages/et_xmlfile-2.0.0.dist-info/WHEEL new file mode 100644 index 0000000..71360e0 --- /dev/null +++ b/venv/lib/python3.12/site-packages/et_xmlfile-2.0.0.dist-info/WHEEL @@ -0,0 +1,5 @@ +Wheel-Version: 1.0 +Generator: setuptools (72.2.0) +Root-Is-Purelib: true +Tag: py3-none-any + diff --git a/venv/lib/python3.12/site-packages/et_xmlfile-2.0.0.dist-info/top_level.txt b/venv/lib/python3.12/site-packages/et_xmlfile-2.0.0.dist-info/top_level.txt new file mode 100644 index 0000000..f573c27 --- /dev/null +++ b/venv/lib/python3.12/site-packages/et_xmlfile-2.0.0.dist-info/top_level.txt @@ -0,0 +1 @@ +et_xmlfile diff --git a/venv/lib/python3.12/site-packages/et_xmlfile/__init__.py b/venv/lib/python3.12/site-packages/et_xmlfile/__init__.py new file mode 100644 index 0000000..776a146 --- /dev/null +++ b/venv/lib/python3.12/site-packages/et_xmlfile/__init__.py @@ -0,0 +1,8 @@ +from .xmlfile import xmlfile + +# constants +__version__ = '2.0.0' +__author__ = 'See AUTHORS.txt' +__license__ = 'MIT' +__author_email__ = 'charlie.clark@clark-consulting.eu' +__url__ = 'https://foss.heptapod.net/openpyxl/et_xmlfile' diff --git a/venv/lib/python3.12/site-packages/et_xmlfile/__pycache__/__init__.cpython-312.pyc b/venv/lib/python3.12/site-packages/et_xmlfile/__pycache__/__init__.cpython-312.pyc new file mode 100644 index 0000000..4a765e2 Binary files /dev/null and b/venv/lib/python3.12/site-packages/et_xmlfile/__pycache__/__init__.cpython-312.pyc differ diff --git a/venv/lib/python3.12/site-packages/et_xmlfile/__pycache__/incremental_tree.cpython-312.pyc b/venv/lib/python3.12/site-packages/et_xmlfile/__pycache__/incremental_tree.cpython-312.pyc new file mode 100644 index 0000000..7e4132b Binary files /dev/null and b/venv/lib/python3.12/site-packages/et_xmlfile/__pycache__/incremental_tree.cpython-312.pyc differ diff --git a/venv/lib/python3.12/site-packages/et_xmlfile/__pycache__/xmlfile.cpython-312.pyc b/venv/lib/python3.12/site-packages/et_xmlfile/__pycache__/xmlfile.cpython-312.pyc new file mode 100644 index 0000000..528952f Binary files /dev/null and b/venv/lib/python3.12/site-packages/et_xmlfile/__pycache__/xmlfile.cpython-312.pyc differ diff --git a/venv/lib/python3.12/site-packages/et_xmlfile/incremental_tree.py b/venv/lib/python3.12/site-packages/et_xmlfile/incremental_tree.py new file mode 100644 index 0000000..b735c1b --- /dev/null +++ b/venv/lib/python3.12/site-packages/et_xmlfile/incremental_tree.py @@ -0,0 +1,917 @@ +# Code modified from cPython's Lib/xml/etree/ElementTree.py +# The write() code is modified to allow specifying a particular namespace +# uri -> prefix mapping. +# +# --------------------------------------------------------------------- +# Licensed to PSF under a Contributor Agreement. +# See https://www.python.org/psf/license for licensing details. +# +# ElementTree +# Copyright (c) 1999-2008 by Fredrik Lundh.

+ +--- + +**Documentation**: https://fastapi.tiangolo.com + +**Source Code**: https://github.com/fastapi/fastapi + +--- + +FastAPI is a modern, fast (high-performance), web framework for building APIs with Python based on standard Python type hints. + +The key features are: + +* **Fast**: Very high performance, on par with **NodeJS** and **Go** (thanks to Starlette and Pydantic). [One of the fastest Python frameworks available](#performance). +* **Fast to code**: Increase the speed to develop features by about 200% to 300%. * +* **Fewer bugs**: Reduce about 40% of human (developer) induced errors. * +* **Intuitive**: Great editor support. Completion everywhere. Less time debugging. +* **Easy**: Designed to be easy to use and learn. Less time reading docs. +* **Short**: Minimize code duplication. Multiple features from each parameter declaration. Fewer bugs. +* **Robust**: Get production-ready code. With automatic interactive documentation. +* **Standards-based**: Based on (and fully compatible with) the open standards for APIs: OpenAPI (previously known as Swagger) and JSON Schema. + +* estimation based on tests on an internal development team, building production applications. + +## Sponsors + + + + + + + + + + + + + + + + + + + + + + + +Other sponsors + +## Opinions + +"_[...] I'm using **FastAPI** a ton these days. [...] I'm actually planning to use it for all of my team's **ML services at Microsoft**. Some of them are getting integrated into the core **Windows** product and some **Office** products._" + +

+ +--- + +## **Typer**, the FastAPI of CLIs + + + +If you are building a CLI app to be used in the terminal instead of a web API, check out **Typer**. + +**Typer** is FastAPI's little sibling. And it's intended to be the **FastAPI of CLIs**. ⌨️ 🚀 + +## Requirements + +FastAPI stands on the shoulders of giants: + +* Starlette for the web parts. +* Pydantic for the data parts. + +## Installation + +Create and activate a virtual environment and then install FastAPI: + +
+ +```console +$ pip install "fastapi[standard]" + +---> 100% +``` + +
+ +**Note**: Make sure you put `"fastapi[standard]"` in quotes to ensure it works in all terminals. + +## Example + +### Create it + +* Create a file `main.py` with: + +```Python +from typing import Union + +from fastapi import FastAPI + +app = FastAPI() + + +@app.get("/") +def read_root(): + return {"Hello": "World"} + + +@app.get("/items/{item_id}") +def read_item(item_id: int, q: Union[str, None] = None): + return {"item_id": item_id, "q": q} +``` + +
+Or use async def... + +If your code uses `async` / `await`, use `async def`: + +```Python hl_lines="9 14" +from typing import Union + +from fastapi import FastAPI + +app = FastAPI() + + +@app.get("/") +async def read_root(): + return {"Hello": "World"} + + +@app.get("/items/{item_id}") +async def read_item(item_id: int, q: Union[str, None] = None): + return {"item_id": item_id, "q": q} +``` + +**Note**: + +If you don't know, check the _"In a hurry?"_ section about `async` and `await` in the docs. + +
+ +### Run it + +Run the server with: + +
+ +```console +$ fastapi dev main.py + + ╭────────── FastAPI CLI - Development mode ───────────╮ + │ │ + │ Serving at: http://127.0.0.1:8000 │ + │ │ + │ API docs: http://127.0.0.1:8000/docs │ + │ │ + │ Running in development mode, for production use: │ + │ │ + │ fastapi run │ + │ │ + ╰─────────────────────────────────────────────────────╯ + +INFO: Will watch for changes in these directories: ['/home/user/code/awesomeapp'] +INFO: Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit) +INFO: Started reloader process [2248755] using WatchFiles +INFO: Started server process [2248757] +INFO: Waiting for application startup. +INFO: Application startup complete. +``` + +

+About the command fastapi dev main.py... + +The command `fastapi dev` reads your `main.py` file, detects the **FastAPI** app in it, and starts a server using Uvicorn. + +By default, `fastapi dev` will start with auto-reload enabled for local development. + +You can read more about it in the FastAPI CLI docs. + +
+ +### Check it + +Open your browser at http://127.0.0.1:8000/items/5?q=somequery. + +You will see the JSON response as: + +```JSON +{"item_id": 5, "q": "somequery"} +``` + +You already created an API that: + +* Receives HTTP requests in the _paths_ `/` and `/items/{item_id}`. +* Both _paths_ take `GET` operations (also known as HTTP _methods_). +* The _path_ `/items/{item_id}` has a _path parameter_ `item_id` that should be an `int`. +* The _path_ `/items/{item_id}` has an optional `str` _query parameter_ `q`. + +### Interactive API docs + +Now go to http://127.0.0.1:8000/docs. + +You will see the automatic interactive API documentation (provided by Swagger UI): + +![Swagger UI](https://fastapi.tiangolo.com/img/index/index-01-swagger-ui-simple.png) + +### Alternative API docs + +And now, go to http://127.0.0.1:8000/redoc. + +You will see the alternative automatic documentation (provided by ReDoc): + +![ReDoc](https://fastapi.tiangolo.com/img/index/index-02-redoc-simple.png) + +## Example upgrade + +Now modify the file `main.py` to receive a body from a `PUT` request. + +Declare the body using standard Python types, thanks to Pydantic. + +```Python hl_lines="4 9-12 25-27" +from typing import Union + +from fastapi import FastAPI +from pydantic import BaseModel + +app = FastAPI() + + +class Item(BaseModel): + name: str + price: float + is_offer: Union[bool, None] = None + + +@app.get("/") +def read_root(): + return {"Hello": "World"} + + +@app.get("/items/{item_id}") +def read_item(item_id: int, q: Union[str, None] = None): + return {"item_id": item_id, "q": q} + + +@app.put("/items/{item_id}") +def update_item(item_id: int, item: Item): + return {"item_name": item.name, "item_id": item_id} +``` + +The `fastapi dev` server should reload automatically. + +### Interactive API docs upgrade + +Now go to http://127.0.0.1:8000/docs. + +* The interactive API documentation will be automatically updated, including the new body: + +![Swagger UI](https://fastapi.tiangolo.com/img/index/index-03-swagger-02.png) + +* Click on the button "Try it out", it allows you to fill the parameters and directly interact with the API: + +![Swagger UI interaction](https://fastapi.tiangolo.com/img/index/index-04-swagger-03.png) + +* Then click on the "Execute" button, the user interface will communicate with your API, send the parameters, get the results and show them on the screen: + +![Swagger UI interaction](https://fastapi.tiangolo.com/img/index/index-05-swagger-04.png) + +### Alternative API docs upgrade + +And now, go to http://127.0.0.1:8000/redoc. + +* The alternative documentation will also reflect the new query parameter and body: + +![ReDoc](https://fastapi.tiangolo.com/img/index/index-06-redoc-02.png) + +### Recap + +In summary, you declare **once** the types of parameters, body, etc. as function parameters. + +You do that with standard modern Python types. + +You don't have to learn a new syntax, the methods or classes of a specific library, etc. + +Just standard **Python**. + +For example, for an `int`: + +```Python +item_id: int +``` + +or for a more complex `Item` model: + +```Python +item: Item +``` + +...and with that single declaration you get: + +* Editor support, including: + * Completion. + * Type checks. +* Validation of data: + * Automatic and clear errors when the data is invalid. + * Validation even for deeply nested JSON objects. +* Conversion of input data: coming from the network to Python data and types. Reading from: + * JSON. + * Path parameters. + * Query parameters. + * Cookies. + * Headers. + * Forms. + * Files. +* Conversion of output data: converting from Python data and types to network data (as JSON): + * Convert Python types (`str`, `int`, `float`, `bool`, `list`, etc). + * `datetime` objects. + * `UUID` objects. + * Database models. + * ...and many more. +* Automatic interactive API documentation, including 2 alternative user interfaces: + * Swagger UI. + * ReDoc. + +--- + +Coming back to the previous code example, **FastAPI** will: + +* Validate that there is an `item_id` in the path for `GET` and `PUT` requests. +* Validate that the `item_id` is of type `int` for `GET` and `PUT` requests. + * If it is not, the client will see a useful, clear error. +* Check if there is an optional query parameter named `q` (as in `http://127.0.0.1:8000/items/foo?q=somequery`) for `GET` requests. + * As the `q` parameter is declared with `= None`, it is optional. + * Without the `None` it would be required (as is the body in the case with `PUT`). +* For `PUT` requests to `/items/{item_id}`, read the body as JSON: + * Check that it has a required attribute `name` that should be a `str`. + * Check that it has a required attribute `price` that has to be a `float`. + * Check that it has an optional attribute `is_offer`, that should be a `bool`, if present. + * All this would also work for deeply nested JSON objects. +* Convert from and to JSON automatically. +* Document everything with OpenAPI, that can be used by: + * Interactive documentation systems. + * Automatic client code generation systems, for many languages. +* Provide 2 interactive documentation web interfaces directly. + +--- + +We just scratched the surface, but you already get the idea of how it all works. + +Try changing the line with: + +```Python + return {"item_name": item.name, "item_id": item_id} +``` + +...from: + +```Python + ... "item_name": item.name ... +``` + +...to: + +```Python + ... "item_price": item.price ... +``` + +...and see how your editor will auto-complete the attributes and know their types: + +![editor support](https://fastapi.tiangolo.com/img/vscode-completion.png) + +For a more complete example including more features, see the Tutorial - User Guide. + +**Spoiler alert**: the tutorial - user guide includes: + +* Declaration of **parameters** from other different places as: **headers**, **cookies**, **form fields** and **files**. +* How to set **validation constraints** as `maximum_length` or `regex`. +* A very powerful and easy to use **Dependency Injection** system. +* Security and authentication, including support for **OAuth2** with **JWT tokens** and **HTTP Basic** auth. +* More advanced (but equally easy) techniques for declaring **deeply nested JSON models** (thanks to Pydantic). +* **GraphQL** integration with Strawberry and other libraries. +* Many extra features (thanks to Starlette) as: + * **WebSockets** + * extremely easy tests based on HTTPX and `pytest` + * **CORS** + * **Cookie Sessions** + * ...and more. + +## Performance + +Independent TechEmpower benchmarks show **FastAPI** applications running under Uvicorn as one of the fastest Python frameworks available, only below Starlette and Uvicorn themselves (used internally by FastAPI). (*) + +To understand more about it, see the section Benchmarks. + +## Dependencies + +FastAPI depends on Pydantic and Starlette. + +### `standard` Dependencies + +When you install FastAPI with `pip install "fastapi[standard]"` it comes the `standard` group of optional dependencies: + +Used by Pydantic: + +* email-validator - for email validation. + +Used by Starlette: + +* httpx - Required if you want to use the `TestClient`. +* jinja2 - Required if you want to use the default template configuration. +* python-multipart - Required if you want to support form "parsing", with `request.form()`. + +Used by FastAPI / Starlette: + +* uvicorn - for the server that loads and serves your application. This includes `uvicorn[standard]`, which includes some dependencies (e.g. `uvloop`) needed for high performance serving. +* `fastapi-cli` - to provide the `fastapi` command. + +### Without `standard` Dependencies + +If you don't want to include the `standard` optional dependencies, you can install with `pip install fastapi` instead of `pip install "fastapi[standard]"`. + +### Additional Optional Dependencies + +There are some additional dependencies you might want to install. + +Additional optional Pydantic dependencies: + +* pydantic-settings - for settings management. +* pydantic-extra-types - for extra types to be used with Pydantic. + +Additional optional FastAPI dependencies: + +* orjson - Required if you want to use `ORJSONResponse`. +* ujson - Required if you want to use `UJSONResponse`. + +## License + +This project is licensed under the terms of the MIT license. diff --git a/venv/lib/python3.12/site-packages/fastapi-0.115.6.dist-info/RECORD

Google refers to these credentials +as *Service Accounts*. + +Service accounts are used for server-to-server communication, such as +interactions between a web application server and a Google service. The +service account belongs to your application instead of to an individual end +user. In contrast to other OAuth 2.0 profiles, no users are involved and your +application "acts" as the service account. + +Typically an application uses a service account when the application uses +Google APIs to work with its own data rather than a user's data. For example, +an application that uses Google Cloud Datastore for data persistence would use +a service account to authenticate its calls to the Google Cloud Datastore API. +However, an application that needs to access a user's Drive documents would +use the normal OAuth 2.0 profile. + +Additionally, Google Apps domain administrators can grant service accounts +`domain-wide delegation`_ authority to access user data on behalf of users in +the domain. + +This profile uses a JWT to acquire an OAuth 2.0 access token. The JWT is used +in place of the usual authorization token returned during the standard +OAuth 2.0 Authorization Code grant. The JWT is only used for this purpose, as +the acquired access token is used as the bearer token when making requests +using these credentials. + +This profile differs from normal OAuth 2.0 profile because no user consent +step is required. The use of the private key allows this profile to assert +identity directly. + +This profile also differs from the :mod:`google.auth.jwt` authentication +because the JWT credentials use the JWT directly as the bearer token. This +profile instead only uses the JWT to obtain an OAuth 2.0 access token. The +obtained OAuth 2.0 access token is used as the bearer token. + +Domain-wide delegation +---------------------- + +Domain-wide delegation allows a service account to access user data on +behalf of any user in a Google Apps domain without consent from the user. +For example, an application that uses the Google Calendar API to add events to +the calendars of all users in a Google Apps domain would use a service account +to access the Google Calendar API on behalf of users. + +The Google Apps administrator must explicitly authorize the service account to +do this. This authorization step is referred to as "delegating domain-wide +authority" to a service account. + +You can use domain-wise delegation by creating a set of credentials with a +specific subject using :meth:`~Credentials.with_subject`. + +.. _RFC 7523: https://tools.ietf.org/html/rfc7523 +""" + +import copy +import datetime +import logging +from typing import Optional, TYPE_CHECKING + + +from google.auth import _helpers +from google.auth import _regional_access_boundary_utils +from google.auth import _service_account_info +from google.auth import credentials +from google.auth import exceptions +from google.auth import iam +from google.auth import jwt +from google.auth import metrics +from google.oauth2 import _client + +if TYPE_CHECKING: # pragma: NO COVER + import google.auth.transport + +_LOGGER = logging.getLogger(__name__) + +_DEFAULT_TOKEN_LIFETIME_SECS = 3600 # 1 hour in seconds +_GOOGLE_OAUTH2_TOKEN_ENDPOINT = "https://oauth2.googleapis.com/token" + + +class Credentials( + credentials.Signing, + credentials.Scoped, + credentials.CredentialsWithQuotaProject, + credentials.CredentialsWithTokenUri, + credentials.CredentialsWithRegionalAccessBoundary, +): + """Service account credentials + + Usually, you'll create these credentials with one of the helper + constructors.

This file is included into docs/history.rst + + +Greenlets are lightweight coroutines for in-process concurrent +programming. + +The "greenlet" package is a spin-off of `Stackless`_, a version of +CPython that supports micro-threads called "tasklets". Tasklets run +pseudo-concurrently (typically in a single or a few OS-level threads) +and are synchronized with data exchanges on "channels". + +A "greenlet", on the other hand, is a still more primitive notion of +micro-thread with no implicit scheduling; coroutines, in other words. +This is useful when you want to control exactly when your code runs. +You can build custom scheduled micro-threads on top of greenlet; +however, it seems that greenlets are useful on their own as a way to +make advanced control flow structures. For example, we can recreate +generators; the difference with Python's own generators is that our +generators can call nested functions and the nested functions can +yield values too. (Additionally, you don't need a "yield" keyword. See +the example in `test_generator.py +`_). + +Greenlets are provided as a C extension module for the regular unmodified +interpreter. + +.. _`Stackless`: http://www.stackless.com + + +Who is using Greenlet? +====================== + +There are several libraries that use Greenlet as a more flexible +alternative to Python's built in coroutine support: + + - `Concurrence`_ + - `Eventlet`_ + - `Gevent`_ + +.. _Concurrence: http://opensource.hyves.org/concurrence/ +.. _Eventlet: http://eventlet.net/ +.. _Gevent: http://www.gevent.org/ + +Getting Greenlet +================ + +The easiest way to get Greenlet is to install it with pip:: + + pip install greenlet + + +Source code archives and binary distributions are available on the +python package index at https://pypi.org/project/greenlet

Making the variables thread-local solves this problem. + * + * When we detected that a greenlet API accessing the current greenlet + * was invoked from a different thread than the greenlet belonged to, + * we stored a reference to the greenlet in the Python thread + * dictionary for the thread the greenlet belonged to.

If a thread exited while still having running + * greenlet objects (perhaps that had just switched back to the main + * greenlet), and did not invoke one of the greenlet APIs *in that + * thread, immediately before it exited, without some other thread + * then being invoked*, such a leak was guaranteed. + * + * This can be partly solved by using compiler thread-local variables + * instead of the Python thread dictionary, thus avoiding a cycle. + * + * To fully solve this problem, we need a reliable way to know that a + * thread is done and we should clean up the main greenlet. On POSIX, + * we can use the destructor function of ``pthread_key_create``, but + * there's nothing similar on Windows; a C++11 thread local object + * reliably invokes its destructor when the thread it belongs to exits + * (non-C++11 compilers offer ``__thread`` or ``declspec(thread)`` to + * create thread-local variables, but they can't hold C++ objects that + * invoke destructors; the C++11 version is the most portable solution + * I found). When the thread exits, we can drop references and + * otherwise manipulate greenlets and frames that we know can no + * longer be switched to. + * + * There are two small wrinkles. The first is that when the thread + * exits, it is too late to actually invoke Python APIs: the Python + * thread state is gone, and the GIL is released. To solve *this* + * problem, our destructor uses ``Py_AddPendingCall`` to transfer the + * destruction work to the main thread. + * + * The second is that once the thread exits, the thread local object + * is invalid and we can't even access a pointer to it, so we can't + * pass it to ``Py_AddPendingCall``.

MSVC on 32-bit windows is an exception. There, C++ + * exceptions are dealt with using Windows' Structured Exception Handling + * (SEH). + * + * SEH is implemented as a singly linked list of nodes. The + * head of this list is stored in the Thread Information Block, which itself + * is pointed to from the FS register. It's the first field in the structure, + * or offset 0, so we can access it using assembly FS:[0], or the compiler + * intrinsics and field offset information from the headers (as we do below). + * Somewhat unusually, the tail of the list doesn't have prev == NULL, it has + * prev == 0xFFFFFFFF. + * + * SEH was designed for C, and traditionally uses the MSVC compiler + * intrinsincs __try{}/__except{}. It is also utilized for C++ exceptions by + * MSVC; there, every throw of a C++ exception raises a SEH error with the + * ExceptionCode 0xE06D7363; the SEH handler list is then traversed to + * deal with the exception. + * + * If the SEH list is corrupt, then when a C++ exception is thrown the program + * will abruptly exit with exit code 1. This does not use std::terminate(), so + * std::set_terminate() is useless to debug this. + * + * The SEH list is closely tied to the call stack; entering a function that + * uses __try{} or most C++ functions will push a new handler onto the front + * of the list. Returning from the function will remove the handler. Saving + * and restoring the head node of the SEH list (FS:[0]) per-greenlet is NOT + * ENOUGH to make SEH or exceptions work. + * + * Stack switching breaks SEH because the call stack no longer necessarily + * matches the SEH list. For example, given greenlet A that switches to + * greenlet B, at the moment of entering greenlet B, we will have any SEH + * handlers from greenlet A on the SEH list; greenlet B can then add its own + * handlers to the SEH list. When greenlet B switches back to greenlet A, + * greenlet B's handlers would still be on the SEH stack, but when switch() + * returns control to greenlet A, we have replaced the contents of the stack + * in memory, so all the address that greenlet B added to the SEH list are now + * invalid: part of the call stack has been unwound, but the SEH list was out + * of sync with the call stack. The net effect is that exception handling + * stops working. + * + * Thus, when switching greenlets, we need to be sure that the SEH list + * matches the effective call stack, "cutting out" any handlers that were + * pushed by the greenlet that switched out and which are no longer valid. + * + * The easiest way to do this is to capture the SEH list at the time the main + * greenlet for a thread is created, and, when initially starting a greenlet, + * start a new SEH list for it, which contains nothing but the handler + * established for the new greenlet itself, with the tail being the handlers + * for the main greenlet. If we then save and restore the SEH per-greenlet, + * they won't interfere with each others SEH lists. (No greenlet can unwind + * the call stack past the handlers established by the main greenlet). + * + * By observation, a new thread starts with three SEH handlers on the list. By + * the time we get around to creating the main greenlet, though, there can be + * many more, established by transient calls that lead to the creation of the + * main greenlet.

But h11 makes it much easier to implement something like +``requests`` or ``twisted.web``. + +At a high level, working with h11 goes like this: + +1) First, create an ``h11.Connection`` object to track the state of a + single HTTP/1.1 connection. + +2) When you read data off the network, pass it to + ``conn.receive_data(...)``; you'll get back a list of objects + representing high-level HTTP "events". + +3) When you want to send a high-level HTTP event, create the + corresponding "event" object and pass it to ``conn.send(...)``; + this will give you back some bytes that you can then push out + through the network. + +For example, a client might instantiate and then send a +``h11.Request`` object, then zero or more ``h11.Data`` objects for the +request body (e.g., if this is a POST), and then a +``h11.EndOfMessage`` to indicate the end of the message. Then the +server would then send back a ``h11.Response``, some ``h11.Data``, and +its own ``h11.EndOfMessage``. If either side violates the protocol, +you'll get a ``h11.ProtocolError`` exception. + +h11 is suitable for implementing both servers and clients, and has a +pleasantly symmetric API: the events you send as a client are exactly +the ones that you receive as a server and vice-versa. + +`Here's an example of a tiny HTTP client +`_ + +It also has `a fine manual `_. + +FAQ +--- + +*Whyyyyy?* + +I wanted to play with HTTP in `Curio +`__ and `Trio +`__, which at the time didn't have any +HTTP libraries. So I thought, no big deal, Python has, like, a dozen +different implementations of HTTP, surely I can find one that's +reusable. I didn't find one, but I did find Cory's call-to-arms +blog-post. So I figured, well, fine, if I have to implement HTTP from +scratch, at least I can make sure no-one *else* has to ever again. + +*Should I use it?* + +Maybe. You should be aware that it's a very young project. But, it's +feature complete and has an exhaustive test-suite and complete docs, +so the next step is for people to try using it and see how it goes +:-). If you do then please let us know -- if nothing else we'll want +to talk to you before making any incompatible changes! + +*What are the features/limitations?* + +Roughly speaking, it's trying to be a robust, complete, and non-hacky +implementation of the first "chapter" of the HTTP/1.1 spec: `RFC 7230: +HTTP/1.1 Message Syntax and Routing +`_. That is, it mostly focuses on +implementing HTTP at the level of taking bytes on and off the wire, +and the headers related to that, and tries to be anal about spec +conformance. It doesn't know about higher-level concerns like URL +routing, conditional GETs, cross-origin cookie policies, or content +negotiation. But it does know how to take care of framing, +cross-version differences in keep-alive handling, and the "obsolete +line folding" rule, so you can focus your energies on the hard / +interesting parts for your application, and it tries to support the +full specification in the sense that any useful HTTP/1.1 conformant +application should be able to use h11. + +It's pure Python, and has no dependencies outside of the standard +library. + +It has a test suite with 100.0% coverage for both statements and +branches. + +Currently it supports Python 3 (testing on 3.8-3.12) and PyPy 3. +The last Python 2-compatible version was h11 0.11.x. +(Originally it had a Cython wrapper for `http-parser +`_ and a beautiful nested state +machine implemented with ``yield from`` to postprocess the output. But +I had to take these out -- the new *parser* needs fewer lines-of-code +than the old *parser wrapper*, is written in pure Python, uses no +exotic language syntax, and has more features. It's sad, really; that +old state machine was really slick. I just need a few sentences here +to mourn that.) + +I don't know how fast it is. I haven't benchmarked or profiled it yet, +so it's probably got a few pointless hot spots, and I've been trying +to err on the side of simplicity and robustness instead of +micro-optimization. But at the architectural level I tried hard to +avoid fundamentally bad decisions, e.g., I believe that all the +parsing algorithms remain linear-time even in the face of pathological +input like slowloris, and there are no byte-by-byte loops. (I also +believe that it maintains bounded memory usage in the face of +arbitrary/pathological input.) + +The whole library is ~800 lines-of-code. You can read and understand +the whole thing in less than an hour. Most of the energy invested in +this so far has been spent on trying to keep things simple by +minimizing special-cases and ad hoc state manipulation; even though it +is now quite small and simple, I'm still annoyed that I haven't +figured out how to make it even smaller and simpler. (Unfortunately, +HTTP does not lend itself to simplicity.) + +The API is ~feature complete and I don't expect the general outlines +to change much, but you can't judge an API's ergonomics until you +actually document and use it, so I'd expect some changes in the +details. + +*How do I try it?* + +.. code-block:: sh + + $ pip install h11 + $ git clone git@github.com:python-hyper/h11 + $ cd h11/examples + $ python basic-client.py + +and go from there. + +*License?* + +MIT + +*Code of conduct?* + +Contributors are requested to follow our `code of conduct +`_ in +all project spaces. diff --git a/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/RECORD b/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/RECORD new file mode 100644 index 0000000..a8f8e63 --- /dev/null +++ b/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/RECORD @@ -0,0 +1,29 @@ +h11-0.16.0.dist-info/INSTALLER,sha256=zuuue4knoyJ-UwPPXg8fezS7VCrXJQrAP7zeNuwvFQg,4 +h11-0.16.0.dist-info/METADATA,sha256=KPMmCYrAn8unm48YD5YIfIQf4kViFct7hyqcfVzRnWQ,8348 +h11-0.16.0.dist-info/RECORD,, +h11-0.16.0.dist-info/WHEEL,sha256=CmyFI0kx5cdEMTLiONQRbGQwjIoR1aIYB7eCAQ4KPJ0,91 +h11-0.16.0.dist-info/licenses/LICENSE.txt,sha256=N9tbuFkm2yikJ6JYZ_ELEjIAOuob5pzLhRE4rbjm82E,1124 +h11-0.16.0.dist-info/top_level.txt,sha256=F7dC4jl3zeh8TGHEPaWJrMbeuoWbS379Gwdi-Yvdcis,4 +h11/__init__.py,sha256=iO1KzkSO42yZ6ffg-VMgbx_ZVTWGUY00nRYEWn-s3kY,1507 +h11/__pycache__/__init__.cpython-312.pyc,, +h11/__pycache__/_abnf.cpython-312.pyc,, +h11/__pycache__/_connection.cpython-312.pyc,, +h11/__pycache__/_events.cpython-312.pyc,, +h11/__pycache__/_headers.cpython-312.pyc,, +h11/__pycache__/_readers.cpython-312.pyc,, +h11/__pycache__/_receivebuffer.cpython-312.pyc,, +h11/__pycache__/_state.cpython-312.pyc,, +h11/__pycache__/_util.cpython-312.pyc,, +h11/__pycache__/_version.cpython-312.pyc,, +h11/__pycache__/_writers.cpython-312.pyc,, +h11/_abnf.py,sha256=ybixr0xsupnkA6GFAyMubuXF6Tc1lb_hF890NgCsfNc,4815 +h11/_connection.py,sha256=k9YRVf6koZqbttBW36xSWaJpWdZwa-xQVU9AHEo9DuI,26863 +h11/_events.py,sha256=I97aXoal1Wu7dkL548BANBUCkOIbe-x5CioYA9IBY14,11792 +h11/_headers.py,sha256=P7D-lBNxHwdLZPLimmYwrPG-9ZkjElvvJZJdZAgSP-4,10412 +h11/_readers.py,sha256=a4RypORUCC3d0q_kxPuBIM7jTD8iLt5X91TH0FsduN4,8590 +h11/_receivebuffer.py,sha256=xrspsdsNgWFxRfQcTXxR8RrdjRXXTK0Io5cQYWpJ1Ws,5252 +h11/_state.py,sha256=_5LG_BGR8FCcFQeBPH-TMHgm_-B-EUcWCnQof_9XjFE,13231 +h11/_util.py,sha256=LWkkjXyJaFlAy6Lt39w73UStklFT5ovcvo0TkY7RYuk,4888 +h11/_version.py,sha256=GVSsbPSPDcOuF6ptfIiXnVJoaEm3ygXbMnqlr_Giahw,686 +h11/_writers.py,sha256=oFKm6PtjeHfbj4RLX7VB7KDc1gIY53gXG3_HR9ltmTA,5081 +h11/py.typed,sha256=sow9soTwP9T_gEAQSVh7Gb8855h04Nwmhs2We-JRgZM,7 diff --git a/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/WHEEL b/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/WHEEL new file mode 100644 index 0000000..1eb3c49 --- /dev/null +++ b/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/WHEEL @@ -0,0 +1,5 @@ +Wheel-Version: 1.0 +Generator: setuptools (78.1.0) +Root-Is-Purelib: true +Tag: py3-none-any + diff --git a/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/licenses/LICENSE.txt b/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/licenses/LICENSE.txt new file mode 100644 index 0000000..8f080ea --- /dev/null +++ b/venv/lib/python3.12/site-packages/h11-0.16.0.dist-info/licenses/LICENSE.txt @@ -0,0 +1,22 @@ +The MIT License (MIT) + +Copyright (c) 2016 Nathaniel J.

The last +# two are stored implicitly in the pending_switch_proposals set as: +# (state of 4) == (_SWITCH_CONNECT in pending_switch_proposals) +# (state of 5) == (_SWITCH_UPGRADE in pending_switch_proposals) +# +# And each of these machines has two different kinds of transitions: +# +# a) Event-triggered +# b) State-triggered +# +# Event triggered is the obvious thing that you'd think it is: some event +# happens, and if it's the right event at the right time then a transition +# happens. But there are somewhat complicated rules for which machines can +# "see" which events. (As a rule of thumb, if a machine "sees" an event, this +# means two things: the event can affect the machine, and if the machine is +# not in a state where it expects that event then it's an error.) These rules +# are: +# +# 1) The client machine sees all h11.events objects emitted by the client. +# +# 2) The server machine sees all h11.events objects emitted by the server. +# +# It also sees the client's Request event. +# +# And sometimes, server events are annotated with a _SWITCH_* event. For +# example, we can have a (Response, _SWITCH_CONNECT) event, which is +# different from a regular Response event. +# +# 3) The keep-alive machine sees the process_keep_alive_disabled() event +# (which is derived from Request/Response events), and this event +# transitions it from True -> False, or from False -> False. There's no way +# to transition back. +# +# 4&5) The _SWITCH_* machines transition from False->True when we get a +# Request that proposes the relevant type of switch (via +# process_client_switch_proposals), and they go from True->False when we +# get a Response that has no _SWITCH_* annotation. +# +# So that's event-triggered transitions. +# +# State-triggered transitions are less standard. What they do here is couple +# the machines together. The way this works is, when certain *joint* +# configurations of states are achieved, then we automatically transition to a +# new *joint* state. So, for example, if we're ever in a joint state with +# +# client: DONE +# keep-alive: False +# +# then the client state immediately transitions to: +# +# client: MUST_CLOSE +# +# This is fundamentally different from an event-based transition, because it +# doesn't matter how we arrived at the {client: DONE, keep-alive: False} state +# -- maybe the client transitioned SEND_BODY -> DONE, or keep-alive +# transitioned True -> False. Either way, once this precondition is satisfied, +# this transition is immediately triggered. +# +# What if two conflicting state-based transitions get enabled at the same +# time? In practice there's only one case where this arises (client DONE -> +# MIGHT_SWITCH_PROTOCOL versus DONE -> MUST_CLOSE), and we resolve it by +# explicitly prioritizing the DONE -> MIGHT_SWITCH_PROTOCOL transition. +# +# Implementation +# -------------- +# +# The event-triggered transitions for the server and client machines are all +# stored explicitly in a table. Ditto for the state-triggered transitions that +# involve just the server and client state. +# +# The transitions for the other machines, and the state-triggered transitions +# that involve the other machines, are written out as explicit Python code. +# +# It'd be nice if there were some cleaner way to do all this.

It +supersedes the standard library's `encodings.idna`, which only +implements the 2003 specification, offering broader script coverage and +limiting domains with known security vulnerabilities. + +## Usage + +Package may be installed from [PyPI](https://pypi.org/project/idna/) via +the typical methods (e.g. `python3 -m pip install idna`) + +For typical usage, the `encode` and `decode` functions will take a +domain name argument and perform a conversion to ASCII-compatible encoding +(known as A-labels), or to Unicode strings (known as U-labels) +respectively. + +```pycon +>>> import idna +>>> idna.encode('ドメイン.テスト') +b'xn--eckwd4c7c.xn--zckzah' +>>> print(idna.decode('xn--eckwd4c7c.xn--zckzah')) +ドメイン.テスト +``` + +Conversions can be applied at a per-label basis using the `ulabel` or +`alabel` functions for specialized use cases. + + +### Compatibility Mapping (UTS #46) + +This library provides support for [Unicode IDNA Compatibility +Processing](https://unicode.org/reports/tr46/) which normalizes input from +different potential ways a user may input a domain prior to performing the IDNA +conversion operations. This functionality, known as a +[mapping](https://tools.ietf.org/html/rfc5895), is considered by the +specification to be a local user-interface issue distinct from IDNA +conversion functionality. + +For example, "Königsgäßchen" is not a permissible label as capital letters +are not allowed. UTS 46 will convert this into lower case prior to applying +the IDNA conversion. + +```pycon +>>> import idna +>>> idna.encode('Königsgäßchen') +... +idna.core.InvalidCodepoint: Codepoint U+004B at position 1 of 'Königsgäßchen' not allowed +>>> idna.encode('Königsgäßchen', uts46=True) +b'xn--knigsgchen-b4a3dun' +>>> idna.decode('xn--knigsgchen-b4a3dun') +'königsgäßchen' +``` + +When performing a decode operation for display purposes, `decode()` +accepts a `display=True` argument that leaves any `xn--` label that +fails to decode unchanged. This is useful for user interface display +where a domain is in use, the A-label form can be presented when it +is not a valid IDN. + + +## Exceptions + +All errors raised during conversion derive from the `idna.IDNAError` +base class. The more specific exceptions are: + +* `idna.IDNABidiError` — raised when a label contains an illegal + combination of left-to-right and right-to-left characters. +* `idna.InvalidCodepoint` — raised when a label contains a codepoint + that is INVALID for IDNA. +* `idna.InvalidCodepointContext` — raised when a CONTEXTO or CONTEXTJ + codepoint appears in a position whose contextual requirements are + not satisfied. + + +## Command-line tool + +The package supports command-line usage to convert domain names +between their Unicode and ASCII-compatible forms. It can be run either +as a module (`python3 -m idna`) or, once installed (such as with `uv +tool` or `pipx`), via the `idna` script: + +```bash +$ uv tool install idna +$ idna xn--e1afmkfd.xn--p1ai +пример.рф +$ idna пример.рф +xn--e1afmkfd.xn--p1ai +``` + +Mode can be specified with `-e`/`--encode` or `-d`/`--decode`, otherwise +it will be chosen automatically based on the first input. Multiple +domains can be supplied either as arguments or through standard input. +UTS #46 mapping is applied by default, which lets the tool accept +inputs that aren't strictly valid IDNA 2008 by normalising them first, +pass `--strict` to disable UTS #46. + +Conversion failures are reported on stderr together with the +offending input; processing continues with the remaining domains and +the tool exits with a non-zero status if any conversion failed. + + +## Additional Notes + +* **Version support**. This library supports Python 3.9 and higher. + As this library serves as a low-level toolkit for a variety of + applications, we strive to support all versions of Python that are + not beyond end-of-life. + +* **Emoji**. It is an occasional request to support emoji domains in + this library. Encoding of symbols like emoji is expressly prohibited by + the IDNA technical standard, and emoji domains are broadly phased + out across the domain industry due to associated security risks. + +* **Regenerating lookup tables**. The IDNA and UTS 46 functionality + relies upon pre-calculated lookup tables, generated using the + `idna-data` script in [`tools/`](tools/README.md). + diff --git a/venv/lib/python3.12/site-packages/idna-3.18.dist-info/RECORD b/venv/lib/python3.12/site-packages/idna-3.18.dist-info/RECORD new file mode 100644 index 0000000..4f507f6 --- /dev/null +++ b/venv/lib/python3.12/site-packages/idna-3.18.dist-info/RECORD @@ -0,0 +1,28 @@ +../../../bin/idna,sha256=SodLm5yFzICuXJNybtPkR814XvdUR1OrbO6l7U1fTDY,233 +idna-3.18.dist-info/INSTALLER,sha256=zuuue4knoyJ-UwPPXg8fezS7VCrXJQrAP7zeNuwvFQg,4 +idna-3.18.dist-info/METADATA,sha256=Rt_m5axGLQ9oDs2avPZugptqIzSCS02eOXmzETXK8oE,6119 +idna-3.18.dist-info/RECORD,, +idna-3.18.dist-info/WHEEL,sha256=G2gURzTEtmeR8nrdXUJfNiB3VYVxigPQ-bEQujpNiNs,82 +idna-3.18.dist-info/entry_points.txt,sha256=7H3nGOHap3jnLE5e7q7Ywr9Vq8axB7WIj5-C_4N2vhw,38 +idna-3.18.dist-info/licenses/LICENSE.md,sha256=GppPDj1HmickDd1ZqRN6ZqtKD539yMphiMwL_YUYfwQ,1541 +idna/__init__.py,sha256=MPqNDLZbXqGaNdXxAFhiqFPKEQXju2jNQhCey6-5eJM,868 +idna/__main__.py,sha256=4JMK66Wj4uLZTKbF-sT3LAxOsr6buig77PmOkJCRRxw,83 +idna/__pycache__/__init__.cpython-312.pyc,, +idna/__pycache__/__main__.cpython-312.pyc,, +idna/__pycache__/cli.cpython-312.pyc,, +idna/__pycache__/codec.cpython-312.pyc,, +idna/__pycache__/compat.cpython-312.pyc,, +idna/__pycache__/core.cpython-312.pyc,, +idna/__pycache__/idnadata.cpython-312.pyc,, +idna/__pycache__/intranges.cpython-312.pyc,, +idna/__pycache__/package_data.cpython-312.pyc,, +idna/__pycache__/uts46data.cpython-312.pyc,, +idna/cli.py,sha256=swqJLMNc8Uzs60KziNpbWnHuqlG3WRQwJSbo4n8xDAo,4139 +idna/codec.py,sha256=JRbo-f7pEkLdWeiH89Z72UR4VBYhvKDFrQBeNX6sRDE,5040 +idna/compat.py,sha256=AepA39ceRHxkfHP41-FvKW5Ki-f4PfUZ90RUMlCNdmo,1353 +idna/core.py,sha256=SfOr1xO3PoE0RDYx7bMciAnjiyjJPbPw_93AB5IUYOw,24685 +idna/idnadata.py,sha256=Af-mo8WBmkhAK6TyXKOQH88OX0mQNDKtdL7UWtQpppk,44862 +idna/intranges.py,sha256=g49scLSkqJtAhLmOODa7hVHriSjmb60tiTsEoocJdBI,1851 +idna/package_data.py,sha256=TeI94EqAFAFaXfBJwsOPUMLn2969uirPa-DaeaceAyU,21 +idna/py.typed,sha256=47DEQpj8HBSa-_TImW-5JCeuQeRkm5NMpJWZG3hSuFU,0 +idna/uts46data.py,sha256=jujNz5QqWMcJf-XYLv4X1jBvb5FlI0t6-e1mILsgbPk,234325 diff --git a/venv/lib/python3.12/site-packages/idna-3.18.dist-info/WHEEL b/venv/lib/python3.12/site-packages/idna-3.18.dist-info/WHEEL new file mode 100644 index 0000000..d8b9936 --- /dev/null +++ b/venv/lib/python3.12/site-packages/idna-3.18.dist-info/WHEEL @@ -0,0 +1,4 @@ +Wheel-Version: 1.0 +Generator: flit 3.12.0 +Root-Is-Purelib: true +Tag: py3-none-any diff --git a/venv/lib/python3.12/site-packages/idna-3.18.dist-info/entry_points.txt b/venv/lib/python3.12/site-packages/idna-3.18.dist-info/entry_points.txt new file mode 100644 index 0000000..59ca7ac --- /dev/null +++ b/venv/lib/python3.12/site-packages/idna-3.18.dist-info/entry_points.txt @@ -0,0 +1,3 @@ +[console_scripts] +idna=idna.cli:main + diff --git a/venv/lib/python3.12/site-packages/idna-3.18.dist-info/licenses/LICENSE.md b/venv/lib/python3.12/site-packages/idna-3.18.dist-info/licenses/LICENSE.md new file mode 100644 index 0000000..f706835 --- /dev/null +++ b/venv/lib/python3.12/site-packages/idna-3.18.dist-info/licenses/LICENSE.md @@ -0,0 +1,31 @@ +BSD 3-Clause License + +Copyright (c) 2013-2026, Kim Davies and contributors. +All rights reserved. + +Redistribution and use in source and binary forms, with or without +modification, are permitted provided that the following conditions are +met: + +1.

When the first request arrives, a window is started for a fixed duration +(e.g., for a rate limit of 10 requests per minute the window expires in 60 seconds from the first request). +All requests in that window increment the counter and when the window expires, the counter resets. + +Burst traffic that bypasses the rate limit may occur at window boundaries. + +For example, with a rate limit of 10 requests per minute: + +- At **00:00:45**, the first request arrives, starting a window from **00:00:45** to **00:01:45**. +- All requests between **00:00:45** and **00:01:45** count toward the limit. +- If 10 requests occur at any time in that window, any further request before **00:01:45** is rejected. +- At **00:01:45**, the counter resets and a new window starts which would allow 10 requests + until **00:02:45**. + +Moving Window +------------- +`Moving Window `_ + +This strategy adds each request’s timestamp to a log if the ``nth`` oldest entry (where ``n`` +is the limit) is either not present or is older than the duration of the window (for example with a rate limit of +``10 requests per minute`` if there are either less than 10 entries or the 10th oldest entry is at least +60 seconds old). Upon adding a new entry to the log "expired" entries are truncated. + +For example, with a rate limit of 10 requests per minute: + +- At **00:00:10**, a client sends 1 requests which are allowed. +- At **00:00:20**, a client sends 2 requests which are allowed. +- At **00:00:30**, the client sends 4 requests which are allowed. +- At **00:00:50**, the client sends 3 requests which are allowed (total = 10). +- At **00:01:11**, the client sends 1 request. The strategy checks the timestamp of the + 10th oldest entry (**00:00:10**) which is now 61 seconds old and thus expired. The request + is allowed. +- At **00:01:12**, the client sends 1 request. The 10th oldest entry's timestamp is **00:00:20** + which is only 52 seconds old. The request is rejected. + +Sliding Window Counter +------------------------ +`Sliding Window Counter `_ + +This strategy approximates the moving window while using less memory by maintaining +two counters: + +- **Current bucket:** counts requests in the ongoing period. +- **Previous bucket:** counts requests in the immediately preceding period. + +When a request arrives, the effective request count is calculated as:: + + weighted_count = current_count + floor(previous_count * weight) + +The weight is based on how much time has elapsed in the current bucket:: + + weight = (bucket_duration - elapsed_time) / bucket_duration + +If ``weighted_count`` is below the limit, the request is allowed. + +For example, with a rate limit of 10 requests per minute: + +Assume: + +- The current bucket (spanning **00:01:00** to **00:02:00**) has 8 hits. +- The previous bucket (spanning **00:00:00** to **00:01:00**) has 4 hits. + +Scenario 1: + +- A new request arrives at **00:01:30**, 30 seconds into the current bucket. +- ``weight = (60 - 30) / 60 = 0.5``. +- ``weighted_count = floor(8 + (4 * 0.5)) = floor(8 + 2) = 10``. +- Since the weighted count equals the limit, the request is rejected. + +Scenario 2: + +- A new request arrives at **00:01:40**, 40 seconds into the current bucket. +- ``weight = (60 - 40) / 60 ≈ 0.33``. +- ``weighted_count = floor(8 + (4 * 0.33)) = floor(8 + 1.32) = 9``. +- Since the weighted count is below the limit, the request is allowed. + + +Storage backends +================ + +- `Redis `_ +- `Memcached `_ +- `MongoDB `_ +- `In-Memory `_ + +Dive right in

It provides a familiar, non-XML +syntax which compiles into Python modules for maximum performance. Mako's +syntax and API borrows from the best ideas of many others, including Django +templates, Cheetah, Myghty, and Genshi. Conceptually, Mako is an embedded +Python (i.e. Python Server Page) language, which refines the familiar ideas +of componentized layout and inheritance to produce one of the most +straightforward and flexible models available, while also maintaining close +ties to Python calling and scoping semantics. + +Nutshell +======== + +:: + + <%inherit file="base.html"/> + <% + rows = [[v for v in range(0,10)] for row in range(0,10)] + %> + + % for row in rows: + ${makerow(row)} + % endfor +

r"""Represents a compiled template. + + :class:`.Template` includes a reference to the original + template source (via the :attr:`.source` attribute) + as well as the source code of the + generated Python module (i.e. the :attr:`.code` attribute), + as well as a reference to an actual Python module. + + :class:`.Template` is constructed using either a literal string + representing the template text, or a filename representing a filesystem + path to a source file. + + :param text: textual template source. This argument is mutually + exclusive versus the ``filename`` parameter. + + :param filename: filename of the source template. This argument is + mutually exclusive versus the ``text`` parameter. + + :param buffer_filters: string list of filters to be applied + to the output of ``%def``\ s which are buffered, cached, or otherwise + filtered, after all filters + defined with the ``%def`` itself have been applied. Allows the + creation of default expression filters that let the output + of return-valued ``%def``\ s "opt out" of that filtering via + passing special attributes or objects. + + :param cache_args: Dictionary of cache configuration arguments that + will be passed to the :class:`.CacheImpl`. See :ref:`caching_toplevel`. + + :param cache_dir: + + .. deprecated:: 0.6 + Use the ``'dir'`` argument in the ``cache_args`` dictionary. + See :ref:`caching_toplevel`. + + :param cache_enabled: Boolean flag which enables caching of this + template. See :ref:`caching_toplevel`. + + :param cache_impl: String name of a :class:`.CacheImpl` caching + implementation to use. Defaults to ``'beaker'``. + + :param cache_type: + + .. deprecated:: 0.6 + Use the ``'type'`` argument in the ``cache_args`` dictionary. + See :ref:`caching_toplevel`. + + :param cache_url: + + .. deprecated:: 0.6 + Use the ``'url'`` argument in the ``cache_args`` dictionary. + See :ref:`caching_toplevel`. + + :param default_filters: List of string filter names that will + be applied to all expressions. See :ref:`filtering_default_filters`. + + :param enable_loop: When ``True``, enable the ``loop`` context variable. + This can be set to ``False`` to support templates that may + be making usage of the name "``loop``". Individual templates can + re-enable the "loop" context by placing the directive + ``enable_loop="True"`` inside the ``<%page>`` tag -- see + :ref:`migrating_loop`. + + :param encoding_errors: Error parameter passed to ``encode()`` when + string encoding is performed. See :ref:`usage_unicode`. + + :param error_handler: Python callable which is called whenever + compile or runtime exceptions occur. The callable is passed + the current context as well as the exception. If the + callable returns ``True``, the exception is considered to + be handled, else it is re-raised after the function + completes. Is used to provide custom error-rendering + functions. + + .. seealso:: + + :paramref:`.Template.include_error_handler` - include-specific + error handler function + + :param format_exceptions: if ``True``, exceptions which occur during + the render phase of this template will be caught and + formatted into an HTML error page, which then becomes the + rendered result of the :meth:`.render` call. Otherwise, + runtime exceptions are propagated outwards. + + :param imports: String list of Python statements, typically individual + "import" lines, which will be placed into the module level + preamble of all generated Python modules. See the example + in :ref:`filtering_default_filters`. + + :param future_imports: String list of names to import from `__future__`. + These will be concatenated into a comma-separated string and inserted + into the beginning of the template, e.g. ``futures_imports=['FOO', + 'BAR']`` results in ``from __future__ import FOO, BAR``. + + :param include_error_handler: An error handler that runs when this template + is included within another one via the ``<%include>`` tag, and raises an + error. Compare to the :paramref:`.Template.error_handler` option. + + .. versionadded:: 1.0.6 + + .. seealso:: + + :paramref:`.Template.error_handler` - top-level error handler function + + :param input_encoding: Encoding of the template's source code. Can + be used in lieu of the coding comment. See + :ref:`usage_unicode` as well as :ref:`unicode_toplevel` for + details on source encoding. + + :param lookup: a :class:`.TemplateLookup` instance that will be used + for all file lookups via the ``<%namespace>``, + ``<%include>``, and ``<%inherit>`` tags. See + :ref:`usage_templatelookup`. + + :param module_directory: Filesystem location where generated + Python module files will be placed. + + :param module_filename: Overrides the filename of the generated + Python module file. For advanced usage only. + + :param module_writer: A callable which overrides how the Python + module is written entirely. The callable is passed the + encoded source content of the module and the destination + path to be written to. The default behavior of module writing + uses a tempfile in conjunction with a file move in order + to make the operation atomic. So a user-defined module + writing function that mimics the default behavior would be: + + .. sourcecode:: python + + import tempfile + import os + import shutil + + def module_writer(source, outputpath): + (dest, name) = \\ + tempfile.mkstemp( + dir=os.path.dirname(outputpath) + ) + + os.write(dest, source) + os.close(dest) + shutil.move(name, outputpath) + + from mako.template import Template + mytemplate = Template( + filename="index.html", + module_directory="/path/to/modules", + module_writer=module_writer + ) + + The function is provided for unusual configurations where + certain platform-specific permissions or other special + steps are needed. + + :param output_encoding: The encoding to use when :meth:`.render` + is called. + See :ref:`usage_unicode` as well as :ref:`unicode_toplevel`. + + :param preprocessor: Python callable which will be passed + the full template source before it is parsed. The return + result of the callable will be used as the template source + code. + + :param lexer_cls: A :class:`.Lexer` class used to parse + the template. The :class:`.Lexer` class is used by + default. + + .. versionadded:: 0.7.4 + + :param strict_undefined: Replaces the automatic usage of + ``UNDEFINED`` for any undeclared variables not located in + the :class:`.Context` with an immediate raise of + ``NameError``. The advantage is immediate reporting of + missing variables which include the name. + + .. versionadded:: 0.3.6 + + :param uri: string URI or other identifier for this template. + If not provided, the ``uri`` is generated from the filesystem + path, or from the in-memory identity of a non-file-based + template.
