It might make sense if +you're writing something like a proxy service in Python, and you just want +something at the lowest possible level, but more typically you'll want to use +a higher level client library, such as `httpx`. + +The motivation for `httpcore` is: + +* To provide a reusable low-level client library, that other packages can then build on top of. +* To provide a *really clear interface split* between the networking code and client logic, + so that each is easier to understand and reason about in isolation. + + +# Changelog + +All notable changes to this project will be documented in this file. + +The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/). + +## 0.17.3 (5th July 2023) + +- Support async cancellations, ensuring that the connection pool is left in a clean state when cancellations occur. (#726) +- The networking backend interface has [been added to the public API](https://www.encode.io/httpcore/network-backends). Some classes which were previously private implementation detail are now part of the top-level public API. (#699) +- Graceful handling of HTTP/2 GoAway frames, with requests being transparently retried on a new connection. (#730) +- Add exceptions when a synchronous `trace callback` is passed to an asynchronous request or an asynchronous `trace callback` is passed to a synchronous request. (#717) + +## 0.17.2 (May 23th, 2023) + +- Add `socket_options` argument to `ConnectionPool` and `HTTProxy` classes. (#668) +- Improve logging with per-module logger names. (#690) +- Add `sni_hostname` request extension. (#696) +- Resolve race condition during import of `anyio` package. (#692) +- Enable TCP_NODELAY for all synchronous sockets. (#651) + +## 0.17.1 (May 17th, 2023) + +- If 'retries' is set, then allow retries if an SSL handshake error occurs. (#669) +- Improve correctness of tracebacks on network exceptions, by raising properly chained exceptions. (#678) +- Prevent connection-hanging behaviour when HTTP/2 connections are closed by a server-sent 'GoAway' frame. (#679) +- Fix edge-case exception when removing requests from the connection pool. (#680) +- Fix pool timeout edge-case. (#688) + +## 0.17.0 (March 16th, 2023) + +- Add DEBUG level logging. (#648) +- Respect HTTP/2 max concurrent streams when settings updates are sent by server. (#652) +- Increase the allowable HTTP header size to 100kB. (#647) +- Add `retries` option to SOCKS proxy classes. (#643) + +## 0.16.3 (December 20th, 2022) + +- Allow `ws` and `wss` schemes. Allows us to properly support websocket upgrade connections. (#625) +- Forwarding HTTP proxies use a connection-per-remote-host. Required by some proxy implementations. (#637) +- Don't raise `RuntimeError` when closing a connection pool with active connections. Removes some error cases when cancellations are used. (#631) +- Lazy import `anyio`, so that it's no longer a hard dependancy, and isn't imported if unused. (#639) + +## 0.16.2 (November 25th, 2022) + +- Revert 'Fix async cancellation behaviour', which introduced race conditions. (#627) +- Raise `RuntimeError` if attempting to us UNIX domain sockets on Windows. (#619) + +## 0.16.1 (November 17th, 2022) + +- Fix HTTP/1.1 interim informational responses, such as "100 Continue".

(#543) + +## 0.14.7 (February 4th, 2022) + +- Requests which raise a PoolTimeout need to be removed from the pool queue. (#502) +- Fix AttributeError that happened when Socks5Connection were terminated. (#501) + +## 0.14.6 (February 1st, 2022) + +- Fix SOCKS support for `http://` URLs. (#492) +- Resolve race condition around exceptions during streaming a response. (#491) + +## 0.14.5 (January 18th, 2022) + +- SOCKS proxy support. (#478) +- Add proxy_auth argument to HTTPProxy.

(#457) +- More robust HTTP/2 handling. (#253, #439, #440, #441) + +## 0.14.3 (November 17th, 2021) + +- Fix race condition when removing closed connections from the pool. (#437) + +## 0.14.2 (November 16th, 2021) + +- Failed connections no longer remain in the pool. (Pull #433) + +## 0.14.1 (November 12th, 2021) + +- `max_connections` becomes optional. (Pull #429) +- `certifi` is now included in the install dependancies. (Pull #428) +- `h2` is now strictly optional. (Pull #428) + +## 0.14.0 (November 11th, 2021) + +The 0.14 release is a complete reworking of `httpcore`, comprehensively addressing some underlying issues in the connection pooling, as well as substantially redesigning the API to be more user friendly. + +Some of the lower-level API design also makes the components more easily testable in isolation, and the package now has 100% test coverage. + +See [discussion #419](https://github.com/encode/httpcore/discussions/419) for a little more background. + +There's some other neat bits in there too, such as the "trace" extension, which gives a hook into inspecting the internal events that occur during the request/response cycle. This extension is needed for the HTTPX cli, in order to... + +* Log the point at which the connection is established, and the IP/port on which it is made. +* Determine if the outgoing request should log as HTTP/1.1 or HTTP/2, rather than having to assume it's HTTP/2 if the --http2 flag was passed. (Which may not actually be true.) +* Log SSL version info / certificate info. + +Note that `curio` support is not currently available in 0.14.0. If you're using `httpcore` with `curio` please get in touch, so we can assess if we ought to prioritize it as a feature or not. + +## 0.13.7 (September 13th, 2021) + +- Fix broken error messaging when URL scheme is missing, or a non HTTP(S) scheme is used. (Pull #403) + +## 0.13.6 (June 15th, 2021) + +### Fixed + +- Close sockets when read or write timeouts occur. (Pull #365) + +## 0.13.5 (June 14th, 2021) + +### Fixed + +- Resolved niggles with AnyIO EOF behaviours. (Pull #358, #362) + +## 0.13.4 (June 9th, 2021) + +### Added + +- Improved error messaging when URL scheme is missing, or a non HTTP(S) scheme is used. (Pull #354) + +### Fixed + +- Switched to `anyio` as the default backend implementation when running with `asyncio`. Resolves some awkward [TLS timeout issues](https://github.com/encode/httpx/discussions/1511). + +## 0.13.3 (May 6th, 2021) + +### Added + +- Support HTTP/2 prior knowledge, using `httpcore.SyncConnectionPool(http1=False)`. (Pull #333) + +### Fixed + +- Handle cases where environment does not provide `select.poll` support. (Pull #331) + +## 0.13.2 (April 29th, 2021) + +### Added + +- Improve error message for specific case of `RemoteProtocolError` where server disconnects without sending a response. (Pull #313) + +## 0.13.1 (April 28th, 2021) + +### Fixed + +- More resiliant testing for closed connections. (Pull #311) +- Don't raise exceptions on ungraceful connection closes. (Pull #310) + +## 0.13.0 (April 21st, 2021) + +The 0.13 release updates the core API in order to match the HTTPX Transport API, +introduced in HTTPX 0.18 onwards. + +An example of making requests with the new interface is: + +```python +with httpcore.SyncConnectionPool() as http: + status_code, headers, stream, extensions = http.handle_request( + method=b'GET', + url=(b'https', b'example.org', 443, b'/'), + headers=[(b'host', b'example.org'), (b'user-agent', b'httpcore')] + stream=httpcore.ByteStream(b''), + extensions={} + ) + body = stream.read() + print(status_code, body) +``` + +### Changed + +- The `.request()` method is now `handle_request()`. (Pull #296) +- The `.arequest()` method is now `.handle_async_request()`. (Pull #296) +- The `headers` argument is no longer optional. (Pull #296) +- The `stream` argument is no longer optional. (Pull #296) +- The `ext` argument is now named `extensions`, and is no longer optional. (Pull #296) +- The `"reason"` extension keyword is now named `"reason_phrase"`. (Pull #296) +- The `"reason_phrase"` and `"http_version"` extensions now use byte strings for their values. (Pull #296) +- The `httpcore.PlainByteStream()` class becomes `httpcore.ByteStream()`. (Pull #296) + +### Added + +- Streams now support a `.read()` interface. (Pull #296) + +### Fixed + +- Task cancellation no longer leaks connections from the connection pool. (Pull #305) + +## 0.12.3 (December 7th, 2020) + +### Fixed + +- Abort SSL connections on close rather than waiting for remote EOF when using `asyncio`. (Pull #167) +- Fix exception raised in case of connect timeouts when using the `anyio` backend. (Pull #236) +- Fix `Host` header precedence for `:authority` in HTTP/2. (Pull #241, #243) +- Handle extra edge case when detecting for socket readability when using `asyncio`. (Pull #242, #244) +- Fix `asyncio` SSL warning when using proxy tunneling. (Pull #249) + +## 0.12.2 (November 20th, 2020) + +### Fixed + +- Properly wrap connect errors on the asyncio backend. (Pull #235) +- Fix `ImportError` occurring on Python 3.9 when using the HTTP/1.1 sync client in a multithreaded context. (Pull #237) + +## 0.12.1 (November 7th, 2020) + +### Added + +- Add connect retries. (Pull #221) + +### Fixed + +- Tweak detection of dropped connections, resolving an issue with open files limits on Linux. (Pull #185) +- Avoid leaking connections when establishing an HTTP tunnel to a proxy has failed. (Pull #223) +- Properly wrap OS errors when using `trio`. (Pull #225) + +## 0.12.0 (October 6th, 2020) + +### Changed + +- HTTP header casing is now preserved, rather than always sent in lowercase. (#216 and python-hyper/h11#104) + +### Added + +- Add Python 3.9 to officially supported versions. + +### Fixed + +- Gracefully handle a stdlib asyncio bug when a connection is closed while it is in a paused-for-reading state. (#201) + +## 0.11.1 (September 28nd, 2020) + +### Fixed + +- Add await to async semaphore release() coroutine (#197) +- Drop incorrect curio classifier (#192) + +## 0.11.0 (September 22nd, 2020) + +The Transport API with 0.11.0 has a couple of significant changes. + +Firstly we've moved changed the request interface in order to allow extensions, which will later enable us to support features +such as trailing headers, HTTP/2 server push, and CONNECT/Upgrade connections. + +The interface changes from: + +```python +def request(method, url, headers, stream, timeout): + return (http_version, status_code, reason, headers, stream) +``` + +To instead including an optional dictionary of extensions on the request and response: + +```python +def request(method, url, headers, stream, ext): + return (status_code, headers, stream, ext) +``` + +Having an open-ended extensions point will allow us to add later support for various optional features, that wouldn't otherwise be supported without these API changes. + +In particular: + +* Trailing headers support. +* HTTP/2 Server Push +* sendfile. +* Exposing raw connection on CONNECT, Upgrade, HTTP/2 bi-di streaming. +* Exposing debug information out of the API, including template name, template context. + +Currently extensions are limited to: + +* request: `timeout` - Optional. 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 #190) +- Update the Transport API to use `.request` and `.arequest` so implementations can support both sync and async. (Pull #189) + +## 0.10.2 (August 20th, 2020) + +### Added + +- Added Unix Domain Socket support. (Pull #139) + +### Fixed + +- Always include the port on proxy CONNECT requests. (Pull #154) +- Fix `max_keepalive_connections` configuration. (Pull #153) +- Fixes behaviour in HTTP/1.1 where server disconnects can be used to signal the end of the response body. (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`. The `AsyncByteSteam` and `SyncByteStream` classes are now pure interface classes. (#133) +- Add `LocalProtocolError`, `RemoteProtocolError` exceptions. (Pull #129) +- Add `UnsupportedProtocol` exception. (Pull #128) +- Add `.get_connection_info()` method. (Pull #102, #137) +- Add better TRACE logs. (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. (Pull #79) + +### Fixed + +- Reuse of connections on HTTP/2 in close concurrency situations. (Pull #81) + +## 0.8.3 (May 6rd, 2020) + +### Fixed + +- Include `Host` and `Accept` headers on proxy "CONNECT" requests. +- De-duplicate any headers also contained in proxy_headers. +- HTTP/2 flag not being passed down to proxy connections. + +## 0.8.2 (May 3rd, 2020) + +### Fixed + +- Fix connections using proxy forwarding requests not being added to the +connection pool properly. (Pull #70) + +## 0.8.1 (April 30th, 2020) + +### Changed + +- Allow inherintance of both `httpcore.AsyncByteStream`, `httpcore.SyncByteStream` without type conflicts. + +## 0.8.0 (April 30th, 2020) + +### Fixed + +- Fixed tunnel proxy support. + +### Added + +- New `TimeoutException` base class. + +## 0.7.0 (March 5th, 2020) + +- First integration with HTTPX. diff --git

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 --help +

+ 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 3.7+. + +## 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.

+# Multi-Dialect Modula-2 Lexer
+class Modula2Lexer(RegexLexer):
+    """
+    For Modula-2 source code.
+
+    The Modula-2 lexer supports several dialects.  By default, it operates in
+    fallback mode, recognising the *combined* literals, punctuation symbols
+    and operators of all supported dialects, and the *combined* reserved words
+    and builtins of PIM Modula-2, ISO Modula-2 and Modula-2 R10, while not
+    differentiating between library defined identifiers.
+
+    To select a specific dialect, a dialect option may be passed
+    or a dialect tag may be embedded into a source file.
+
+    Dialect Options:
+
+    `m2pim`
+        Select PIM Modula-2 dialect.
+    `m2iso`
+        Select ISO Modula-2 dialect.
+    `m2r10`
+        Select Modula-2 R10 dialect.
+    `objm2`
+        Select Objective Modula-2 dialect.
+
+    The PIM and ISO dialect options may be qualified with a language extension.
+
+    Language Extensions:
+
+    `+aglet`
+        Select Aglet Modula-2 extensions, available with m2iso.
+    `+gm2`
+        Select GNU Modula-2 extensions, available with m2pim.
+    `+p1`
+        Select p1 Modula-2 extensions, available with m2iso.
+    `+xds`
+        Select XDS Modula-2 extensions, available with m2iso.
+
+
+    Passing a Dialect Option via Unix Commandline Interface
+
+    Dialect options may be passed to the lexer using the `dialect` key.
+    Only one such option should be passed. If multiple dialect options are
+    passed, the first valid option is used, any subsequent options are ignored.
+
+    Examples:
+
+    `$ pygmentize -O full,dialect=m2iso -f html -o /path/to/output /path/to/input`
+        Use ISO dialect to render input to HTML output
+    `$ pygmentize -O full,dialect=m2iso+p1 -f rtf -o /path/to/output /path/to/input`
+        Use ISO dialect with p1 extensions to render input to RTF output
+
+
+    Embedding a Dialect Option within a source file
+
+    A dialect option may be embedded in a source file in form of a dialect
+    tag, a specially formatted comment that specifies a dialect option.
+
+    Dialect Tag EBNF::
+
+       dialectTag :
+           OpeningCommentDelim Prefix dialectOption ClosingCommentDelim ;
+
+       dialectOption :
+           'm2pim' | 'm2iso' | 'm2r10' | 'objm2' |
+           'm2iso+aglet' | 'm2pim+gm2' | 'm2iso+p1' | 'm2iso+xds' ;
+
+       Prefix : '!' ;
+
+       OpeningCommentDelim : '(*' ;
+
+       ClosingCommentDelim : '*)' ;
+
+    No whitespace is permitted between the tokens of a dialect tag.
+
+    In the event that a source file contains multiple dialect tags, the first
+    tag that contains a valid dialect option will be used and any subsequent
+    dialect tags will be ignored.  Ideally, a dialect tag should be placed
+    at the beginning of a source file.
+
+    An embedded dialect tag overrides a dialect option set via command line.
+
+    Examples:
+
+    ``(*!m2r10*) DEFINITION MODULE Foobar; ...``
+        Use Modula2 R10 dialect to render this source file.
+    ``(*!m2pim+gm2*) DEFINITION MODULE Bazbam; ...``
+        Use PIM dialect with GNU extensions to render this source file.
+
+
+    Algol Publication Mode:
+
+    In Algol publication mode, source text is rendered for publication of
+    algorithms in scientific papers and academic texts, following the format
+    of the Revised Algol-60 Language Report.  It is activated by passing
+    one of two corresponding styles as an option:
+
+    `algol`
+        render reserved words lowercase underline boldface
+        and builtins lowercase boldface italic
+    `algol_nu`
+        render reserved words lowercase boldface (no underlining)
+        and builtins lowercase boldface italic
+
+    The lexer automatically performs the required lowercase conversion when
+    this mode is activated.
+
+    Example:
+
+    ``$ pygmentize -O full,style=algol -f latex -o /path/to/output /path/to/input``
+        Render input file in Algol publication mode to LaTeX output.
+
+
+    Rendering Mode of First Class ADT Identifiers:
+
+    The rendering of standard library first class ADT identifiers is controlled
+    by option flag "treat_stdlib_adts_as_builtins".
+
+    When this option is turned on, standard library ADT identifiers are rendered
+    as builtins.  When it is turned off, they are rendered as ordinary library
+    identifiers.
+
+    `treat_stdlib_adts_as_builtins` (default: On)
+
+    The option is useful for dialects that support ADTs as first class objects
+    and provide ADTs in the standard library that would otherwise be built-in.
+
+    At present, only Modula-2 R10 supports library ADTs as first class objects
+    and therefore, no ADT identifiers are defined for any other dialects.
+
+    Example:
+
+    ``$ pygmentize -O full,dialect=m2r10,treat_stdlib_adts_as_builtins=Off ...``
+        Render standard library ADTs as ordinary library types.
