There is a very rare case where the maxval is improperly computed
initially for cache loading progress, and the value will go over.
Explanation from bitbake/lib/bb/cache.py:736 in MulticonfigCache:__init__:progress()
# we might have calculated incorrect total size because a file
# might've been written out just after we checked its size
In that case, progressbar will receive a value over the initial maxval.
This results in a ValueError stack trace as well as bitbake returning 1.
Traceback (most recent call last):
File ".../poky/bitbake/lib/bb/ui/knotty.py", line 736, in main
cacheprogress.update(event.current)
File ".../poky/bitbake/lib/progressbar/progressbar.py", line 256, in update
raise ValueError('Value out of range')
ValueError: Value out of range
This fix mirrors the behavior of MulticonfigCache and accepts the new
value as the new maxval. This is also what the percentage printout
is doing in bitbake/lib/progressbar/progressbar.py:191 in ProgressBar:percentage()
I encountered this issue randomly while working on a project with
VSCode saving files while commands where fired.
Note: This file is a fork from python-progressbar. It hasn't been
refreshed in 8 years. We did only two commits, 5 years ago with minor
modifications. This new change is also not how the upstream project is
behaving.

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: https://docs.yoctoproject.org
Bitbake requires Python version 3.8 or newer.
Contributing
Please refer to our contributor guide here: https://docs.yoctoproject.org/contributor-guide/ for full details on how to submit changes.
As a quick guide, patches should be sent to bitbake-devel@lists.openembedded.org The git command to do that would be:
git send-email -M -1 --to bitbake-devel@lists.openembedded.org
If you're sending a patch related to the BitBake manual, make sure you copy the Yocto Project documentation mailing list:
git send-email -M -1 --to bitbake-devel@lists.openembedded.org --cc docs@lists.yoctoproject.org

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.
To run the tests "zstd" and "git" must be installed.
The assumption is made that this testsuite is run from an initialized OpenEmbedded build
environment (i.e. source oe-init-build-env is used). If this is not the case, run the
testsuite as follows:
export PATH=$(pwd)/bin:$PATH
bin/bitbake-selftest
The testsuite can alternatively be executed using pytest, e.g. obtained from PyPI (in this case, the PATH is configured automatically):
pytest
