Peter Kjellerstedt 88993ae030 bitbake: fetch2: Correct handling of replacing the basename in URIs
The solution implementated in commit 96c30007 (fetch2: fix
downloadfilename issue with premirror) missed two corner cases. The
first is if the basename of the original URI also appears somewhere
else in the replacement URI, in which case it would also be replaced.
The second is if the basename of the original URI partially matches
the basename of the replacement URI, in which case the inital part of
the basename from the replacement URI would be left behind.

The second case caused test_npm_premirrors_with_specified_filename to
fail.

The solution is to prefix the basename with a slash when matching to
avoid partial matches, and only replace the basename at the end of the
URI.

This also adds two test cases that test for these problems. Before
this they would give the following errors:

  - ['file:///mirror/example/1.0.0/some-example-1.0.0.tgz;downloadfilename=some-example-1.0.0.tgz']
  + ['file:///mirror/some-example-1.0.0.tgz/1.0.0/some-example-1.0.0.tgz;downloadfilename=some-example-1.0.0.tgz']
  ?                  +++++       ++++++++++

  - ['file:///mirror/some-example-1.0.0.tgz;downloadfilename=some-example-1.0.0.tgz']
  + ['file:///mirror/some-some-example-1.0.0.tgz;downloadfilename=some-example-1.0.0.tgz']
  ?                  +++++

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

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.
