linux/poky.git/bitbake/lib/bb/asyncrpc, branch master

The poky repository master branch is no longer being updated.

2025-11-07T13:31:53+00:00

You can either: a) switch to individual clones of bitbake, openembedded-core, meta-yocto and yocto-docs b) use the new bitbake-setup You can find information about either approach in our documentation: https://docs.yoctoproject.org/ Note that "poky" the distro setting is still available in meta-yocto as before and we continue to use and maintain that. Long live Poky! Some further information on the background of this change can be found in: https://lists.openembedded.org/g/openembedded-architecture/message/2179 Signed-off-by: Richard Purdie

bitbake: Use a "fork" multiprocessing context

2025-07-23T10:34:31+00:00

Python 3.14 changes the default multiprocessing context from "fork" to "forkserver"; however bitbake heavily relies on "fork" to efficiently pass data to the child processes. As such, make "fork" context in the bb namespace and use it in place of the normal multiprocessing module. Note that multiprocessing contexts were added in Python 3.4, so this should be safe to use even before Python 3.14 [YOCTO #15858] (Bitbake rev: 62be9113d98fccb347c6aa0a10d5c4ee2857f8b6) Signed-off-by: Joshua Watt Signed-off-by: Richard Purdie

bitbake: asyncrpc: Avoid file not found traceback in logs

2025-07-17T09:45:57+00:00

If the server is quickly stopped, we see tracebacks in the locks due to the file not existing. Hide these as they're not errors. (Bitbake rev: a7e1a07e9ef7e6f6a1bcaf567d7916a8ee1ef087) Signed-off-by: Richard Purdie

bitbake: asyncrpc: Handle websockets exceptions

2025-01-11T18:35:01+00:00

The websockets library throws a number of exceptions which are currently not caught leading to unhandled exceptions in the idle loop. Fix this by catching them and reexposing them as a `ConnectionError` which is the exception expected by users of `asyncrpc`.

bitbake: asyncrpc: Use client timeout for websocket open timeout

2024-06-04T11:05:20+00:00

The default connection timeout for websockets is 10 seconds, so use the provided client timeout instead (which defaults to 30 seconds). (Bitbake rev: 23681775e5941e54ebead469addf708fca1e6beb) Signed-off-by: Joshua Watt Signed-off-by: Richard Purdie

bitbake: asyncrpc: Remove ClientPool

2024-05-31T15:56:25+00:00

Batching support on the client side has proven to be a much more effective way of dealing with server latency than multiple client connections and is also much nicer on the server, so drop the client pool support from asyncrpc and the hash server (Bitbake rev: 6f80560f1c7010d09fe5448fdde616aef8468102) Signed-off-by: Joshua Watt Signed-off-by: Richard Purdie

bitbake: bitbake: Drop older python version compatibility code

2024-05-31T15:56:25+00:00

cooker: We can call multiprocessing close() unconditionally and tweak a comment give 3.8 is now the minimum version. lib/bb: We can drop the logger addition code only needed before 3.6 asyncrpc/hashserv: Since the minimum version is 3.8, we can drop the conditional code.

bitbake: hashserv: server: Add support for SO_REUSEPORT

2024-05-30T06:38:10+00:00

SO_REUSEPORT is a socket option that allows multiple servers to listen on the same TCP port, and the kernel will automatically load balance the connections between them. This is particularly helpful for the hash server since it runs in a single thread. To take advantage of a multi-core server, multiple servers can be started in parallel with this option (up to 1 per CPU) and the kernel will load balance between them.

bitbake: asyncrpc/client: Fix websockets minimum version for python 3.10

2024-05-16T09:52:43+00:00

python 3.10 support is only available in websockets 10.0 and later: https://github.com/python-websockets/websockets/commit/08d8011132ba038b3f6c4d591189b57af4c9f147 Update the version for this case. This avoids failures on Ubuntu 22.04. (Bitbake rev: 0e4767c4a880408750e1a6855270c5a4eef8383d) Signed-off-by: Richard Purdie

bitbake: asyncrpc: Check websockets version

2024-05-08T13:51:44+00:00

Checks that the minimum version of the websockets module is present, and if not raises an ImportError. This allows the user to get earlier feedback if using websockets is going to succeed (Bitbake rev: 330ea6914aad65dc8b34c986c44779820c392f03) Signed-off-by: Joshua Watt Signed-off-by: Richard Purdie
