We had an issue where a webserver serving sstate had filesystem issues so would accept connections but effectively not do anything with them. This causes bitbake to hang whilst processing things like sstate objects inside the checkstatus() calls. It can be replicated by setting up a server like: socat -u TCP4-LISTEN:NNN,fork OPEN:/dev/null and pointing SSTATE_MIRRORS in OE at that address. Adding a timeout to the checkstatus calls of 15s means that whilst the system will pause, it will then continue and not hang entirely. Since there isn't a large transfer here, 30s should be a reasonable response time after which we should fall back to building things ourselves.

Bitbake
=======
BitBake is a generic task execution engine that allows shell and Python tasks to be run
efficiently and in parallel while working within complex inter-task dependency constraints.
One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software
stacks using a task-oriented approach.
For information about Bitbake, see the OpenEmbedded website:
https://www.openembedded.org/
Bitbake plain documentation can be found under the doc directory or its integrated
html version at the Yocto Project website:

Contributing
------------
Please refer to
https://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded
for guidelines on how to submit patches, just note that the latter documentation is intended
for OpenEmbedded (and its core) not bitbake patches (bitbake-devel@lists.openembedded.org)
but in general main guidelines apply. Once the commit(s) have been created, the way to send
the patch is through git-send-email. For example, to send the last commit (HEAD) on current
branch, type:
git send-email -M -1 --to bitbake-devel@lists.openembedded.org
Mailing list:
https://lists.openembedded.org/g/bitbake-devel

Testing:
Bitbake has a testsuite located in lib/bb/tests/ whichs aim to try and prevent regressions.
You can run this with "bitbake-selftest". In particular the fetcher is well covered since
it has so many corner cases. The datastore has many tests too. Testing with the testsuite is
recommended before submitting patches, particularly to the fetcher and datastore. We also
appreciate new test cases and may require them for more obscure issues.
