- Stop adding the directory of every .capnp file to the import path. If a .capnp
file wants to import a file in its own directory, it should use a relative
import. Fixes#278
- Stop using /usr/include/capnp as an import path. This is incorrect. It should
only be /usr/include.
- Stop allowing additional paths to be specified for magic imports. This leads
to inconsistencies. More specifically, the way that a nested import like
`ma.mb.mc_capnp` gets imported by python, is to first import `ma`, then import
`ma.mb`, and finally `ma.mb.mc_capnp`. Pycapnp's magic importing is only
involved in the last step. So any additional paths specified don't work for
nested imports. It is very confusing to only have this for non-nested imports.
Users with folder layouts that don't follow pythons import paths can still use
`capnp.load(.., .., imports=[blah])`.
See the test for an explanation.
Note that I'm not sure what the purpose of `_setDynamicFieldWithField` and
`_setDynamicFieldStatic` is. It does not appear to be used. I've kept them for
now (they are a public API), but perhaps this can be removed.
This was already fixed in c9bea05f44, but the fix does not seem to work.
This commit uses a set union, which should be more robust. It also adds
a couple of assertions to verify that it indeed works.
* add capnp_api.h to gitignore
* Change type of read_min_bytes from size to int
Not sure why this was not causing issues before or if that
is the right fix ... but it seems to be fine :)
* Adapt python_requires to >=3.8
This was overlooked when 3.7 was deprecated. The ci no longer
works with python 3.7 and cibuildwheel uses python_requires ...
* Replace deprecated find_module with find_spec (importlib)
find_module was deprecated with python 3.4 and python 3.12
removed it (https://docs.python.org/3.12/whatsnew/3.12.html#importlib).
The new command is find_spec and only required a few adaptions
Cap'n Proto provides a schema loader, which can be used to dynamically
load schemas during runtime. To port this functionality to pycapnp,
a new class is provided `C_SchemaLoader`, which exposes the Cap'n
Proto C++ interface, and `SchemaLoader`, which is part of the pycapnp
library.
The specific use case for this is when a capnp message contains
a Node.Reader: The schema for a yet unseen message can be loaded
dynamically, allowing the future message to be properly processed.
If the message is a struct containing other structs, all the schemas for
every struct must be loaded to correctly parse the message. See
https://github.com/DaneSlattery/capnp_generic_poc for a
proof-of-concept.
Add docs and cleanup

Fix flake8 formatting

All of these tests also exist in test_capability.py. The only difference is the
way the .capnp file is loaded. But that could be tested with much less code.
* Integrate the KJ event loop into Python's asyncio event loop
Fix#256
This PR attempts to remove the slow and expensive polling behavior for asyncio
in favor of proper linking of the KJ event loop to the asyncio event loop.
* Don't memcopy buffer
* Improve promise cancellation and prepare for timer implementation
* Add attribution for asyncProvider.cpp
* Implement timeout
* Cleanup
* First round of simplifications
* Add more a_wait functions and a shutdown function
* Fix edge-cases with loop shutdown
* Clean up calculator examples
* Cleanup
* Cleanup
* Reformat
* Fix warnings
* Reformat again
* Compatibility with macos
* Inline the asyncio loop in some places where this is feasible
* Add todo
* Fix
* Remove synchronous wait
* Wrap fd listening callbacks in a class
* Remove poll_forever
* Remove the thread-local/thread-global optimization
This will not matter much soon anyway, and simplifies things
* Share promise code by using fused types
* Improve refcounting of python objects in promises
We replace many instances of PyObject* by Own<PyRefCounter> for more automatic
reference management.
* Code wrapPyFunc in a similar way to wrapPyFuncNoArg
* Refactor capabilityHelper, fix several memory bugs for promises and add __await__
* Improve promise ownership, reduce memory leaks
Promise wrappers now hold a Own<Promise<Own<PyRefCounter>>> object. This might
seem like excessive nesting of objects (which to some degree it is, but with
good reason):
- The outer Own is needed because Cython cannot allocate objects without a
nullary constructor on the stack (Promise doesn't have a nullary constructor).
Additionally, I believe it would be difficult or impossible to detect when a
promise is cancelled/moved if we use a bare Promise.
- Every promise returns a Owned PyRefCounter. PyRefCounter makes sure that a
reference to the returned object keeps existing until the promise is fulfilled
or cancelled. Previously, this was attempted using attach, which is redundant
and makes reasoning about PyINCREF and PyDECREF very difficult.
- Because a promise holds a Own<Promise<...>>, when we perform any kind of
action on that promise (a_wait, then, ...), we have to explicitly move() the
ownership around. This will leave the original promise with a NULL-pointer,
which we can easily detect as a cancelled promise.
Promises now only hold references to their 'parents' when strictly needed. This
should reduce memory pressure.
* Simplify and test the promise joining functionality
* Attach forgotten parent
* Catch exceptions in add_reader and friends
* Further cleanup of memory leaks
* Get rid of a_wait() in examples
* Cancel all fd read operations when the python asyncio loop is closed
* Formatting
* Remove support for capnp < 7000
* Bring asyncProvider.cpp more in line with upstream async-io-unix.c++
It was originally copied from the nodejs implementation, which in turn copied
from async-io-unix.c++. But that copy is pretty old.
* Fix a bug that caused file descriptors to never be closed
* Implement AsyncIoStream based on Python transports and protocols
* Get rid of asyncProvider
All asyncio now goes through _AsyncIoStream
* Formatting
* Add __dict__ to PyAsyncIoStreamProtocol for python 3.7
* Reintroduce strange ipv4/ipv6 selection code to make ci happy
* Extra pause_reading()
* Work around more python bugs
* Be careful to only close transport when this is still possible
* Move pause_reading() workaround
- Full cleanup of all the docs
- General sphinx housekeeping
- Updated all the old/bad links
- More reliable tests
- Updated Changelog
- Removed dead/deprecated code
- Added documentation generation test
- Includes some test stabilization
- Fixes manylinux2010 build issues (linker flag order due to old gcc)
- More rigorous python setup.py clean
- Requires capnproto v0.8.0 or greater
- Including system libcapnp include path for import (e.g. import
stream_capnp)
- Bundle libcapnp .capnp files when not using system libcapnp
- Removing more distutils usage. Now using pkg-config to determine the
system version of libcapnp (mainly for Linux, but should work on macOS
with brew)
- Removed dead code
Resolves issues #215#216#217
Lots of fixes for Issue #218 (all sorts of retry methods needed for
GitHub Actions)
- Adding import path filter to exclude non-directories
Otherwise kj will through exceptions
- Skipped AF_UNIX socket test
- Use default socket configuration when it doesn't matter the type of
socket used
- Open files with utf8 encoding (needed for text validation)
- Explictly call python executable when running external scripts
- Fix path creation to always use os.path.join
- Added timeout to client wait in some tests
- Some broken tests still remain (most likely asyncio related)
- Not recommended to be used in new designs
- Just pollutes warning messages during compilation (hiding ones that
should be fixed)
- Updated test code to use bootstrap
- Sped up some of the test code that was just sleeping while waiting for
the server (now polling for the socket)
- async_reconnecting_ssl_client.py will automatically close and
reconnect to a server when it becomes available (rather than hanging or
dying when the server disappears)
- This way they will be included in CI checks
- Decreased the delay time in the thread-like examples to speed up tests
(probably could decrease the time some more)
- Added an async version of the calculator test
- Forcing python3 support for example scripts
- Needed to include cleanup_global_schema_parser() to handle duplicate
imports of the same .capnp file
* Duplicate IDs are a problem as pytest does not fully cleanup between
tests
- Marked some tests as xfail as I'm not sure the test is supposed to
work anymore with recent versions of capnproto
flake8 . --count --exit-zero --max-complexity=10 --max-line-length=127 --statistics --exclude benchmark
Excluding the benchmark directory (due to protobuf generated files)
Also removing some Python2 specific code
