Some distributions (namely Fedora Core 40) have started replacing
wget with wget2. There are some changes to wget2 that make it
incompatible with wget:
1. ftp/ftps is not supported anymore
2. progress 'dot' is not yet supported
3. Relative paths in -P and -O are not correctly dealt with
Item 1: Is already dealt with since Scarthgap by only adding the
option --passive-ftp when the URL specifies ftp/sftp. While that
won't help if ftp/sftp is actually required it at least does
not break http/https downloads.
Item 2: While not supported it at least does not break the operation.
Item 3: If there are relative path components in -P or -O then wget2
only deals with them correctly if there is one, and only one, relative
path component at the beginning of the path:
-P ./downloads works
-P ../downloads works
-P ../../downloads does not work
-P ./../downloads does not work
-P /home/user/downloads/../downloads does not work
In cases where there are more than one relative path component at
the beginning of the path and/or one or more reltaive path
component somewhere in the middle or end of the path, wget2 aborts
with the message Internal error: Unexpected relative path: '<path>')
Such can happen if DL_DIR includes relative path components e.g.
DL_DIR = "${TOPDIR}/../../downloads".
This patch canonicalizes DL_DIR before it is passed to wget.

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
