Various optionally supported features might require specification of custom +extra require, e.g. `pip install fsspec[ssh]` will install dependencies for `ssh` backends support. +Use `pip install fsspec[full]` for installation of all known extra dependencies. + +Up-to-date package also provided through conda-forge distribution: + +```bash +conda install -c conda-forge fsspec +``` + + +## Purpose + +To produce a template or specification for a file-system interface, that specific implementations should follow, +so that applications making use of them can rely on a common behaviour and not have to worry about the specific +internal implementation decisions with any given backend. Many such implementations are included in this package, +or in sister projects such as `s3fs` and `gcsfs`. + +In addition, if this is well-designed, then additional functionality, such as a key-value store or FUSE +mounting of the file-system implementation may be available for all implementations "for free". + +## Documentation + +Please refer to [RTD](https://filesystem-spec.readthedocs.io/en/latest/?badge=latest) + +## Develop + +fsspec uses GitHub Actions for CI. Environment files can be found +in the "ci/" directory. Note that the main environment is called "py38", +but it is expected that the version of python installed be adjustable at +CI runtime. For local use, pick a version suitable for you. + +```bash +# For a new environment (mamba / conda). +mamba create -n fsspec -c conda-forge python=3.10 -y +conda activate fsspec + +# Standard dev install with docs and tests. +pip install -e ".[dev,doc,test]" + +# Full tests except for downstream +pip install s3fs +pip uninstall s3fs +pip install -e .[dev,doc,test_full] +pip install s3fs --no-deps +pytest -v + +# Downstream tests. +sh install_s3fs.sh +# Windows powershell. +install_s3fs.sh +``` + +### Testing + +Tests can be run in the dev environment, if activated, via ``pytest fsspec``. + +The full fsspec suite requires a system-level docker, docker-compose, and fuse +installation. If only making changes to one backend implementation, it is +not generally necessary to run all tests locally. + +It is expected that contributors ensure that any change to fsspec does not +cause issues or regressions for either other fsspec-related packages such +as gcsfs and s3fs, nor for downstream users of fsspec. The "downstream" CI +run and corresponding environment file run a set of tests from the dask +test suite, and very minimal tests against pandas and zarr from the +test_downstream.py module in this repo. + +### Code Formatting + +fsspec uses [Black](https://black.readthedocs.io/en/stable) to ensure +a consistent code format throughout the project. +Run ``black fsspec`` from the root of the filesystem_spec repository to +auto-format your code. Additionally, many editors have plugins that will apply +``black`` as you edit files. ``black`` is included in the ``tox`` environments. + +Optionally, you may wish to setup [pre-commit hooks](https://pre-commit.com) to +automatically run ``black`` when you make a git commit. +Run ``pre-commit install --install-hooks`` from the root of the +filesystem_spec repository to setup pre-commit hooks. ``black`` will now be run +before you commit, reformatting any changed files. You can format without +committing via ``pre-commit run`` or skip these checks with ``git commit +--no-verify``. + +## Support + +Work on this repository is supported in part by: + +"Anaconda, Inc. -

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. 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 0000000000000000000000000000000000000000..a8f8e63f529ce81b7d7c970ea791147d9a732175 --- /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 0000000000000000000000000000000000000000..1eb3c49d99559863120cfb8433fc8738fba43ba9 --- /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 0000000000000000000000000000000000000000..8f080eae848f759c9173bfc0c79506357ebe5090 --- /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.

(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... + +

+ +## 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/transports/#wsgi-transport) or [ASGI applications](https://www.python-httpx.org/advanced/transports/#asgi-transport). +* 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]`)* +* `zstandard` - Decoding for "zstd" compressed responses. *(Optional, with `httpx[zstd]`)* + +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.

With modularization design, +it is easy to use and extend. It supports media data like images and videos +very well, and can also be applied to texts and other type of files. +Scrapy is heavy and powerful, while icrawler is tiny and flexible. + +With this package, you can write a multiple thread crawler easily by focusing on +the contents you want to crawl, keeping away from troublesome problems like +exception handling, thread scheduling and communication. + +It also provides built-in crawlers for popular image sites like **Flickr** and +search engines such as **Google**, **Bing** and **Baidu**. +(Thank all the contributors and pull requests are always welcome!) + +Requirements +------------ + +Python 3.5+ (recommended). + +Examples +-------- + +Using built-in crawlers is very simple. A minimal example is shown as follows. + +.. code:: python + + from icrawler.builtin import GoogleImageCrawler + + google_crawler = GoogleImageCrawler(storage={'root_dir': 'your_image_dir'}) + google_crawler.crawl(keyword='cat', max_num=100) + +You can also configurate number of threads and apply advanced search options. +(Note: compatible with 0.6.0 and later versions) + +.. code:: python + + from icrawler.builtin import GoogleImageCrawler + + google_crawler = GoogleImageCrawler( + feeder_threads=1, + parser_threads=2, + downloader_threads=4, + storage={'root_dir': 'your_image_dir'}) + filters = dict( + size='large', + color='orange', + license='commercial,modify', + date=((2017, 1, 1), (2017, 11, 30))) + google_crawler.crawl(keyword='cat', filters=filters, max_num=1000, file_idx_offset=0) + +For more advanced usage about built-in crawlers, please refer to the +`documentation `_. + +Writing your own crawlers with this framework is also convenient, see the +`tutorials `_. + +Architecture +------------ + +A crawler consists of 3 main components (Feeder, Parser and Downloader), +they are connected with each other with FIFO queues. The workflow is shown in +the following figure. + +.. figure:: http://7xopqn.com1.z0.glb.clouddn.com/workflow.png + :alt: + +- ``url_queue`` stores the url of pages which may contain images +- ``task_queue`` stores the image url as well as any meta data you + like, each element in the queue is a dictionary and must contain the + field ``img_url`` +- Feeder puts page urls to ``url_queue`` +- Parser requests and parses the page, then extracts the image urls and + puts them into ``task_queue`` +- Downloader gets tasks from ``task_queue`` and requests the images, + then saves them in the given path. + +Feeder, parser and downloader are all thread pools, so you can specify the +number of threads they use. diff --git a/.venv/lib/python3.12/site-packages/icrawler-0.6.10.dist-info/RECORD

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 (such as `disallowed_codepoint` or +`label_too_long`); and, when the failure can be attributed to a +particular character, `text` (the label or domain being validated), +`codepoint` (the offending codepoint as an integer) and `position` +are set. + + +## 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**. 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-3.20.dist-info/RECORD b/.venv/lib/python3.12/site-packages/idna-3.20.dist-info/RECORD new file mode 100644 index 0000000000000000000000000000000000000000..8efcb2f47ecf03fd35932f99439e7f01ddb02993 --- /dev/null +++ b/.venv/lib/python3.12/site-packages/idna-3.20.dist-info/RECORD @@ -0,0 +1,28 @@ +../../../bin/idna,sha256=fBd2tVwwcnYfXcQAOLtcexCeT-NmMAAfKQME-T-6VHk,239 +idna-3.20.dist-info/INSTALLER,sha256=zuuue4knoyJ-UwPPXg8fezS7VCrXJQrAP7zeNuwvFQg,4 +idna-3.20.dist-info/METADATA,sha256=29jBTB5MoeDJgkptvHy794iE8461LZEUjNMCX2ceS4U,7207 +idna-3.20.dist-info/RECORD,, +idna-3.20.dist-info/WHEEL,sha256=lqN8jXt_QloFOGcx9kStvWbryhfEXoI2F2z-YURm350,81 +idna-3.20.dist-info/entry_points.txt,sha256=7H3nGOHap3jnLE5e7q7Ywr9Vq8axB7WIj5-C_4N2vhw,38 +idna-3.20.dist-info/licenses/LICENSE.md,sha256=GppPDj1HmickDd1ZqRN6ZqtKD539yMphiMwL_YUYfwQ,1541 +idna/__init__.py,sha256=hRTD7VMTajWW699RL6SHu919pama3K7YLgNj0sMG068,944 +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=LgGXKiXmev37pdgkATwB6AiJORZTnA2zP3LzfEK4iWo,4245 +idna/codec.py,sha256=ff9CR9debiZcvqEmHxDRIrqSmaNxQpz6AY4JHsC3YC0,8002 +idna/compat.py,sha256=T_eZXOUt0b5Tga56cPybQu9CCYK0FTK1mdiPb96na8A,1376 +idna/core.py,sha256=PdTD_-5P8iMgf6xl84EqHmiVrorR56btYBFXaPNVFSA,32580 +idna/idnadata.py,sha256=I6mowdFd6cY00L8hPXeYEPSFCD_hsPfgkEStBKacx-s,45763 +idna/intranges.py,sha256=g49scLSkqJtAhLmOODa7hVHriSjmb60tiTsEoocJdBI,1851 +idna/package_data.py,sha256=rnWVNKPFgqAKyFbPykZKOe6CUdOTII2K8GtgW8IOAqk,21 +idna/py.typed,sha256=47DEQpj8HBSa-_TImW-5JCeuQeRkm5NMpJWZG3hSuFU,0 +idna/uts46data.py,sha256=dw6Em_oVbHGCiolEClf-mupwc18QOuRhbuT2guE9bAA,237174 diff --git a/.venv/lib/python3.12/site-packages/idna-3.20.dist-info/WHEEL b/.venv/lib/python3.12/site-packages/idna-3.20.dist-info/WHEEL new file mode 100644 index 0000000000000000000000000000000000000000..1ab9a08b3a505f2f5a1a39db576a05c639c3baf8 --- /dev/null +++ b/.venv/lib/python3.12/site-packages/idna-3.20.dist-info/WHEEL @@ -0,0 +1,4 @@ +Wheel-Version: 1.0 +Generator: flit 4.1.0 +Root-Is-Purelib: true +Tag: py3-none-any diff --git a/.venv/lib/python3.12/site-packages/idna-3.20.dist-info/entry_points.txt b/.venv/lib/python3.12/site-packages/idna-3.20.dist-info/entry_points.txt new file mode 100644 index 0000000000000000000000000000000000000000..59ca7ac02ea0a40938ca867305e020981f52a077 --- /dev/null +++ b/.venv/lib/python3.12/site-packages/idna-3.20.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-3.20.dist-info/licenses/LICENSE.md b/.venv/lib/python3.12/site-packages/idna-3.20.dist-info/licenses/LICENSE.md new file mode 100644 index 0000000000000000000000000000000000000000..f706835ab3a5dd709a6e1f57aee0a94ae1415df6 --- /dev/null +++ b/.venv/lib/python3.12/site-packages/idna-3.20.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.

The default is lex, which + orders terms lexicographically (e.g., x**2 + x + 1). You can choose + other orderings, such as rev-lex, which will use reverse + lexicographic ordering (e.g., 1 + x + x**2): + + $isympy -o rev-lex + + ORDER must be one of 'lex', 'rev-lex', 'grlex', 'rev-grlex', + 'grevlex', 'rev-grevlex', 'old', or 'none'. + + Note that for very large expressions, ORDER='none' may speed up + printing considerably but the terms will have no canonical order. + +-q, --quiet + + Print only Python's and SymPy's versions to stdout at startup. + +-d, --doctest + + Use the same format that should be used for doctests. This is + equivalent to -c python -p no. + +-C, --no-cache + + Disable the caching mechanism. Disabling the cache may slow certain + operations down considerably.

You can delete existing names by executing "del + name". If a name is defined, typing "'name' in dir()" will return True. + + The Symbols that are created using this have default assumptions. + If you want to place assumptions on symbols, you should create them + using symbols() or var(). + + Finally, this only works in the top level namespace. So, for + example, if you define a function in isympy with an undefined + Symbol, it will not work. + + See also the -i and -I options. + +-i, --int-to-Integer (requires at least IPython 0.11) + + Automatically wrap int literals with Integer. This makes it so that + things like 1/2 will come out as Rational(1, 2), rather than 0.5. This + works by preprocessing the source and wrapping all int literals with + Integer. Note that this will not change the behavior of int literals + assigned to variables, and it also won't change the behavior of functions + that return int literals. + + If you want an int, you can wrap the literal in int(), e.g. int(3)/int(2) + gives 1.5 (with division imported from __future__). + +-I, --interactive (requires at least IPython 0.11) + + This is equivalent to --auto-symbols --int-to-Integer.

Defaults to ``'%}'``. + + `variable_start_string` + The string marking the beginning of a print statement. + Defaults to ``'{{'``. + + `variable_end_string` + The string marking the end of a print statement. Defaults to + ``'}}'``. + + `comment_start_string` + The string marking the beginning of a comment. Defaults to ``'{#'``. + + `comment_end_string` + The string marking the end of a comment. Defaults to ``'#}'``. + + `line_statement_prefix` + If given and a string, this will be used as prefix for line based + statements. See also :ref:`line-statements`. + + `line_comment_prefix` + If given and a string, this will be used as prefix for line based + comments. See also :ref:`line-statements`. + + .. versionadded:: 2.2 + + `trim_blocks` + If this is set to ``True`` the first newline after a block is + removed (block, not variable tag!). Defaults to `False`. + + `lstrip_blocks` + If this is set to ``True`` leading spaces and tabs are stripped + from the start of a line to a block. Defaults to `False`. + + `newline_sequence` + The sequence that starts a newline. Must be one of ``'\r'``, + ``'\n'`` or ``'\r\n'``. The default is ``'\n'`` which is a + useful default for Linux and OS X systems as well as web + applications. + + `keep_trailing_newline` + Preserve the trailing newline when rendering templates. + The default is ``False``, which causes a single newline, + if present, to be stripped from the end of the template. + + .. versionadded:: 2.7 + + `extensions` + List of Jinja extensions to use. This can either be import paths + as strings or extension classes. For more information have a + look at :ref:`the extensions documentation `. + + `optimized` + should the optimizer be enabled? Default is ``True``. + + `undefined` + :class:`Undefined` or a subclass of it that is used to represent + undefined values in the template. + + `finalize` + A callable that can be used to process the result of a variable + expression before it is output. For example one can convert + ``None`` implicitly into an empty string here. + + `autoescape` + If set to ``True`` the XML/HTML autoescaping feature is enabled by + default. For more details about autoescaping see + :class:`~markupsafe.Markup`. As of Jinja 2.4 this can also + be a callable that is passed the template name and has to + return ``True`` or ``False`` depending on autoescape should be + enabled by default. + + .. versionchanged:: 2.4 + `autoescape` can now be a function + + `loader` + The template loader for this environment. + + `cache_size` + The size of the cache. Per default this is ``400`` which means + that if more than 400 templates are loaded the loader will clean + out the least recently used template. If the cache size is set to + ``0`` templates are recompiled all the time, if the cache size is + ``-1`` the cache will not be cleaned. + + .. versionchanged:: 2.8 + The cache size was increased to 400 from a low 50. + + `auto_reload` + Some loaders load templates from locations where the template + sources may change (ie: file system or database). If + ``auto_reload`` is set to ``True`` (default) every time a template is + requested the loader checks if the source changed and if yes, it + will reload the template. For higher performance it's possible to + disable that. + + `bytecode_cache` + If set to a bytecode cache object, this object will provide a + cache for the internal Jinja bytecode so that templates don't + have to be parsed if they were not changed. + + See :ref:`bytecode-cache` for more information. + + `enable_async` + If set to true this enables async template execution which + allows using async functions and generators. + """ + + #: if this environment is sandboxed.
