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/python3.11/site-packages/annotated_types-0.8.0.dist-info/RECORD b/venv/lib/python3.11/site-packages/annotated_types-0.8.0.dist-info/RECORD new file mode 100755 index 0000000..7444769 --- /dev/null +++ b/venv/lib/python3.11/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-311.pyc,, +annotated_types/__pycache__/test_cases.cpython-311.pyc,, +annotated_types/py.typed,sha256=47DEQpj8HBSa-_TImW-5JCeuQeRkm5NMpJWZG3hSuFU,0 +annotated_types/test_cases.py,sha256=2GdHKstXuBzpf3iXKCjmvFZpyk2zP9Hm9kXGGDhGBo4,6310 diff --git a/venv/lib/python3.11/site-packages/annotated_types-0.8.0.dist-info/WHEEL b/venv/lib/python3.11/site-packages/annotated_types-0.8.0.dist-info/WHEEL new file mode 100755 index 0000000..7401812 --- /dev/null +++ b/venv/lib/python3.11/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/python3.11/site-packages/annotated_types-0.8.0.dist-info/licenses/LICENSE b/venv/lib/python3.11/site-packages/annotated_types-0.8.0.dist-info/licenses/LICENSE new file mode 100755 index 0000000..d99323a --- /dev/null +++ b/venv/lib/python3.11/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.

It implements Trio-like `structured concurrency`_ (SC) on top of asyncio and works in harmony +with the native SC of Trio itself. + +Applications and libraries written against AnyIO's API will run unmodified on either asyncio_ or +Trio_. AnyIO can also be adopted into a library or application incrementally – bit by bit, no full +refactoring necessary. It will blend in with the native libraries of your chosen backend. + +To find out why you might want to use AnyIO's APIs instead of asyncio's, you can read about it +`here `_. + +Documentation +------------- + +View full documentation at: https://anyio.readthedocs.io/ + +Features +-------- + +AnyIO offers the following functionality: + +* Task groups (nurseries_ in trio terminology) +* 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 Hypothesis_ library. + +.. _asyncio: https://docs.python.org/3/library/asyncio.html +.. _Trio: https://github.com/python-trio/trio +.. _structured concurrency:

Simply install it with ``pip``:: + + $ pip install certifi + +Usage +----- + +To reference the installed certificate authority (CA) bundle, you can use the +built-in function:: + + >>> import certifi + + >>> certifi.where() + '/usr/local/lib/python3.7/site-packages/certifi/cacert.pem' + +Or from the command line:: + + $ python -m certifi + /usr/local/lib/python3.7/site-packages/certifi/cacert.pem + +Enjoy! + +.. _`Requests`: https://requests.readthedocs.io/en/latest/ + +Addition/Removal of Certificates +-------------------------------- + +Certifi does not support any addition/removal or other modification of the +CA trust store content. This project is intended to provide a reliable and +highly portable root of trust to python deployments.

+ +[^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.

Its predecessor function +[`platform.dist`](https://docs.python.org/3.7/library/platform.html#platform.dist) +was already deprecated since Python 2.6 and removed in Python 3.8. Still, there +are many cases in which access to that information is needed. See [Python issue +1322](https://bugs.python.org/issue1322) for more information. + +The `distro` package implements a robust and inclusive way of retrieving the +information about a distribution based on new standards and old methods, +namely from these data sources (from high to low precedence): + +* The os-release file `/etc/os-release` if present, with a fall-back on `/usr/lib/os-release` if needed. +* The output of the `lsb_release` command, if available. +* The distro release file (`/etc/*(-|_)(release|version)`), if present. +* The `uname` command for BSD based distrubtions. + + +## Python and Distribution Support + +`distro` is supported and tested on Python 3.6+ and PyPy and on any +distribution that provides one or more of the data sources covered. + +This package is tested with test data that mimics the exact behavior of the data sources of [a number of Linux distributions](https://github.com/python-distro/distro/tree/master/tests/resources/distros). + + +## Testing + +```shell +git clone git@github.com:python-distro/distro.git +cd distro +pip install tox +tox +``` + + +## Contributions + +Pull requests are always welcome to deal with specific distributions or just

This means you can hook h11 up to your favorite network +API, and that could be anything you want: synchronous, threaded, +asynchronous, or your own implementation of `RFC 6214 +`_ -- h11 won't judge you. +(Compare this to the current state of the art, where every time a `new +network API `_ comes along then someone +gets to start over reimplementing the entire HTTP protocol from +scratch.) Cory Benfield made an `excellent blog post describing the +benefits of this approach +`_, or if you like video +then here's his `PyCon 2016 talk on the same theme +`_. + +This also means that h11 is not immediately useful out of the box: +it's a toolkit for building programs that speak HTTP, not something +that could directly replace ``requests`` or ``twisted.web`` or +whatever. 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.

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. This isn't +# *too* terrible, but I feel like it could probably be better. +# +# WARNING +# ------- +# +# The script that generates the state machine diagrams for the docs knows how +# to read out the EVENT_TRIGGERED_TRANSITIONS and STATE_TRIGGERED_TRANSITIONS +# tables. But it can't automatically read the transitions that are written +# directly in Python code. So if you touch those, you need to also update the +# script to keep it in sync! +from typing import cast, Dict, Optional, Set, Tuple, Type, Union + +from ._events import * +from ._util import LocalProtocolError, Sentinel + +# Everything in __all__ gets re-exported as part of the h11 public API. +__all__ = [ + "CLIENT", + "SERVER", + "IDLE", + "SEND_RESPONSE", + "SEND_BODY", + "DONE", + "MUST_CLOSE", + "CLOSED", + "MIGHT_SWITCH_PROTOCOL", + "SWITCHED_PROTOCOL", + "ERROR", +] + + +class CLIENT(Sentinel, metaclass=Sentinel): + pass + + +class SERVER(Sentinel, metaclass=Sentinel): + pass + + +# States +class IDLE(Sentinel, metaclass=Sentinel): + pass + + +class SEND_RESPONSE(Sentinel, metaclass=Sentinel): + pass + + +class SEND_BODY(Sentinel, metaclass=Sentinel): + pass + + +class DONE(Sentinel, metaclass=Sentinel): + pass + + +class MUST_CLOSE(Sentinel, metaclass=Sentinel): + pass + + +class CLOSED(Sentinel, metaclass=Sentinel): + pass + + +class ERROR(Sentinel, metaclass=Sentinel): + pass + + +# Switch types +class MIGHT_SWITCH_PROTOCOL(Sentinel, metaclass=Sentinel): + pass + + +class SWITCHED_PROTOCOL(Sentinel, metaclass=Sentinel): + pass + + +class _SWITCH_UPGRADE(Sentinel, metaclass=Sentinel): + pass + + +class _SWITCH_CONNECT(Sentinel, metaclass=Sentinel): + pass + + +EventTransitionType = Dict[ + Type[Sentinel], + Dict[ + Type[Sentinel], + Dict[Union[Type[Event], Tuple[Type[Event], Type[Sentinel]]], Type[Sentinel]], + ], +] + +EVENT_TRIGGERED_TRANSITIONS: EventTransitionType = { + CLIENT: { + IDLE: {Request: SEND_BODY, ConnectionClosed: CLOSED}, + SEND_BODY: {Data: SEND_BODY, EndOfMessage: DONE}, + DONE: {ConnectionClosed: CLOSED}, + MUST_CLOSE: {ConnectionClosed: CLOSED}, + CLOSED: {ConnectionClosed: CLOSED}, + MIGHT_SWITCH_PROTOCOL: {}, + SWITCHED_PROTOCOL: {}, + ERROR: {}, + }, + SERVER: { + IDLE: { + ConnectionClosed: CLOSED, + Response: SEND_BODY, + # Special case: server sees client Request events, in this form + (Request, CLIENT): SEND_RESPONSE, + }, + SEND_RESPONSE: { + InformationalResponse: SEND_RESPONSE, + Response: SEND_BODY, + (InformationalResponse, _SWITCH_UPGRADE): SWITCHED_PROTOCOL, + (Response, _SWITCH_CONNECT): SWITCHED_PROTOCOL, + }, + SEND_BODY: {Data: SEND_BODY, EndOfMessage: DONE}, + DONE: {ConnectionClosed: CLOSED}, + MUST_CLOSE: {ConnectionClosed: CLOSED}, + CLOSED: {ConnectionClosed: CLOSED}, + SWITCHED_PROTOCOL: {}, + ERROR: {}, + }, +} + +StateTransitionType = Dict[ + Tuple[Type[Sentinel], Type[Sentinel]], Dict[Type[Sentinel], Type[Sentinel]] +] + +# NB: there are also some special-case state-triggered transitions hard-coded +# into _fire_state_triggered_transitions below. +STATE_TRIGGERED_TRANSITIONS: StateTransitionType = { + # (Client state, Server state) -> new states + # Protocol negotiation + (MIGHT_SWITCH_PROTOCOL, SWITCHED_PROTOCOL): {CLIENT: SWITCHED_PROTOCOL}, + # Socket shutdown + (CLOSED, DONE): {SERVER: MUST_CLOSE}, + (CLOSED, IDLE): {SERVER: MUST_CLOSE}, + (ERROR, DONE): {SERVER: MUST_CLOSE}, + (DONE, CLOSED): {CLIENT: MUST_CLOSE}, + (IDLE, CLOSED): {CLIENT: MUST_CLOSE}, + (DONE, ERROR): {CLIENT: MUST_CLOSE}, +} + + +class ConnectionState: + def __init__(self) -> None: + # Extra bits of state that don't quite fit into the state model. + + # If this is False then it enables the automatic DONE -> MUST_CLOSE + # transition.

Timeout dictionary. +* response: `http_version` - Optional. Include the HTTP version used on the response. +* response: `reason` - Optional. Include the reason phrase used on the response. Only valid with HTTP/1.*. + +See https://github.com/encode/httpx/issues/1274#issuecomment-694884553 for the history behind this. + +Secondly, the async version of `request` is now namespaced as `arequest`. + +This allows concrete transports to support both sync and async implementations on the same class. + +### Added + +- Add curio support. (Pull #168) +- Add anyio support, with `backend="anyio"`. (Pull #169) + +### Changed + +- Update the Transport API to use 'ext' for optional extensions.

(Pull #164) + +## 0.10.1 (August 7th, 2020) + +- Include `max_keepalive_connections` on `AsyncHTTPProxy`/`SyncHTTPProxy` classes. + +## 0.10.0 (August 7th, 2020) + +The most notable change in the 0.10.0 release is that HTTP/2 support is now fully optional. + +Use either `pip install httpcore` for HTTP/1.1 support only, or `pip install httpcore[http2]` for HTTP/1.1 and HTTP/2 support. + +### Added + +- HTTP/2 support becomes optional. (Pull #121, #130) +- Add `local_address=...` support. (Pull #100, #134) +- Add `PlainByteStream`, `IteratorByteStream`, `AsyncIteratorByteStream`.

(Pull #101) + +### Changed + +- `max_keepalive` is deprecated in favour of `max_keepalive_connections`. (Pull #140) + +### Fixed + +- Improve handling of server disconnects. (Pull #112) + +## 0.9.1 (May 27th, 2020) + +### Fixed + +- Proper host resolution for sync case, including IPv6 support. (Pull #97) +- Close outstanding connections when connection pool is closed. (Pull #98) + +## 0.9.0 (May 21th, 2020) + +### Changed + +- URL port becomes an `Optional[int]` instead of `int`. (Pull #92) + +### Fixed + +- Honor HTTP/2 max concurrent streams settings. (Pull #89, #90) +- Remove incorrect debug log. (Pull #83) + +## 0.8.4 (May 11th, 2020) + +### Added + +- Logging via HTTPCORE_LOG_LEVEL and HTTPX_LOG_LEVEL environment variables +and TRACE level logging.

HTTPX - A next-generation HTTP client for Python.

+ +

+ + Test Suite + + + Package version + +

+ +HTTPX is a fully featured HTTP client library for Python 3. It includes **an integrated +command line client**, has support for both **HTTP/1.1 and HTTP/2**, and provides both **sync +and async APIs**. + +--- + +Install HTTPX using pip: + +```shell +$ pip install httpx +``` + +Now, let's get started: + +```pycon +>>> import httpx +>>> r = httpx.get('https://www.example.org/') +>>> r + +>>> r.status_code +200 +>>> r.headers['content-type'] +'text/html; charset=UTF-8' +>>> r.text +'\n\n\nExample Domain...' +``` + +Or, using the command-line client. + +```shell +$ pip install 'httpx[cli]' # The command line client is an optional dependency. +``` + +Which now allows us to use HTTPX directly from the command-line... + +

+ httpx http://httpbin.org/json +

+ +## Features + +HTTPX builds on the well-established usability of `requests`, and gives you: + +* A broadly [requests-compatible API](https://www.python-httpx.org/compatibility/). +* An integrated command-line client. +* HTTP/1.1 [and HTTP/2 support](https://www.python-httpx.org/http2/). +* Standard synchronous interface, but with [async support if you need it](https://www.python-httpx.org/async/). +* Ability to make requests directly to [WSGI applications](https://www.python-httpx.org/advanced/#calling-into-python-web-apps) or [ASGI applications](https://www.python-httpx.org/async/#calling-into-python-web-apps). +* Strict timeouts everywhere. +* Fully type annotated. +* 100% test coverage. + +Plus all the standard features of `requests`... + +* International Domains and URLs +* Keep-Alive & Connection Pooling +* Sessions with Cookie Persistence +* Browser-style SSL Verification +* Basic/Digest Authentication +* Elegant Key/Value Cookies +* Automatic Decompression +* Automatic Content Decoding +* Unicode Response Bodies +* Multipart File Uploads +* HTTP(S) Proxy Support +* Connection Timeouts +* Streaming Downloads +* .netrc Support +* Chunked Requests + +## Installation + +Install with pip: + +```shell +$ pip install httpx +``` + +Or, to include the optional HTTP/2 support, use: + +```shell +$ pip install httpx[http2] +``` + +HTTPX requires Python 3.8+. + +## Documentation + +Project documentation is available at [https://www.python-httpx.org/](https://www.python-httpx.org/). + +For a run-through of all the basics, head over to the [QuickStart](https://www.python-httpx.org/quickstart/). + +For more advanced topics, see the [Advanced Usage](https://www.python-httpx.org/advanced/) section, the [async support](https://www.python-httpx.org/async/) section, or the [HTTP/2](https://www.python-httpx.org/http2/) section. + +The [Developer Interface](https://www.python-httpx.org/api/) provides a comprehensive API reference. + +To find out about tools that integrate with HTTPX, see [Third Party Packages](https://www.python-httpx.org/third_party_packages/). + +## Contribute + +If you want to contribute with HTTPX check out the [Contributing Guide](https://www.python-httpx.org/contributing/) to learn how to start. + +## Dependencies + +The HTTPX project relies on these excellent libraries: + +* `httpcore` - The underlying transport implementation for `httpx`. + * `h11` - HTTP/1.1 support. +* `certifi` - SSL certificates. +* `idna` - Internationalized domain name support. +* `sniffio` - Async library autodetection. + +As well as these optional installs: + +* `h2` - HTTP/2 support. *(Optional, with `httpx[http2]`)* +* `socksio` - SOCKS proxy support. *(Optional, with `httpx[socks]`)* +* `rich` - Rich terminal support. *(Optional, with `httpx[cli]`)* +* `click` - Command line client support. *(Optional, with `httpx[cli]`)* +* `brotli` or `brotlicffi` - Decoding for "brotli" compressed responses. *(Optional, with `httpx[brotli]`)* + +A huge amount of credit is due to `requests` for the API layout that +much of this work follows, as well as to `urllib3` for plenty of design +inspiration around the lower-level networking details. + +--- + +

HTTPX is BSD licensed code.
Designed & crafted with care.

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. + +Exceptions carry machine-readable attributes so that applications +do not need to parse the message: `code` is a short, stable identifier +for the rule that failed (listed below); and, when the failure can be +attributed to a particular character, `text` (the label, or domain for +UTS #46 processing, being validated), `codepoint` (the offending +codepoint as an integer) and `position` (its 1-based index within +`text`, as quoted in the message) are set. Each is `None` when it does +not apply. Message wording is not part of the API and may change. + +```pycon +>>> try: +... idna.encode('Königsgäßchen') +... except idna.IDNAError as err: +... print(err.code, err.codepoint, err.position, err.text) +disallowed_codepoint 75 1 Königsgäßchen +``` + +| `code` | Meaning | +|---|---| +| `input_too_long` | Input exceeds the library's defensive length limit and was not processed | +| `label_too_long` | A label exceeds 63 octets | +| `domain_too_long` | The domain exceeds 253 octets | +| `empty_label` | A label is empty (e.g. consecutive dots) | +| `empty_domain` | The domain is empty | +| `not_nfc` | The label is not in Unicode Normalization Form C | +| `hyphen_3_4` | The label has hyphens in the 3rd and 4th positions | +| `hyphen_start_end` | The label starts or ends with a hyphen | +| `leading_combiner` | The label starts with a combining mark | +| `disallowed_codepoint` | A codepoint is DISALLOWED or UNASSIGNED under IDNA 2008 | +| `contextj` | A CONTEXTJ codepoint (joiner) appears in an invalid context | +| `contexto` | A CONTEXTO codepoint appears in an invalid context | +| `unknown_codepoint` | A codepoint next to a joiner is unknown to this Python's Unicode database | +| `bidi_rule_1` … `bidi_rule_6` | The corresponding rule of RFC 5893 (the Bidi Rule) is violated | +| `bidi_unknown_direction` | A codepoint's directionality is unknown to this Python's Unicode database | +| `invalid_alabel` | An `xn--` label is malformed or is not valid Punycode | +| `non_canonical_alabel` | An `xn--` label is not the canonical Punycode encoding of its U-label (a "fake A-label") | +| `invalid_ascii` | Byte input is not ASCII | +| `invalid_utf8` | Byte input is not UTF-8 | +| `uts46_disallowed` | A codepoint is disallowed by the UTS #46 mapping table | +| `uts46_std3` | An ASCII character is rejected by the UTS #46 STD3 rules | +| `unsupported_errors` | The codec was given an `errors` handler other than `strict` | + + +## 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 + +* **Python 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. Free-threaded Python is also supported, + as the library holds no mutable global state the functions can be + called concurrently from multiple threads. + +* **Unicode version**. The IDNA and UTS #46 lookup tables are generated + from a specific Unicode release. Some Unicode data depends on the + running Python's `unicodedata` module, so on an older Python a + character new to Unicode may be rejected as unknown even if this + library knows about it. + +* **Emoji**.
