[pve-devel] [PATCH storage v3 1/4] fix #3972: Remove the .notes file when a backup is deleted

[pve-devel] [PATCH storage v3 1/4] fix #3972: Remove the .notes file when a backup is deleted

[Daniel Tschlatscher]

When a VM or Container backup was deleted, the .notes file was not
removed, therefore, over time the dump folder would get polluted with
notes for backups that no longer existed. As backup names contain a
timestamp and as the notes cannot be reused because of this, I think
it is safe to just delete them just like we do with the .log file.

Furthermore, I sourced the deletion of the log and notes file into a
new function called "archive_auxiliaries_remove". Additionally, the
archive_info object now returns one more field containing the name of
the notes file. The test cases have to be adapted to expect this new
value as the package will not compile otherwise.

[pve-devel] [PATCH storage v3 2/4] fix #3972: Adapted unlink calls for archive files in case of ENOENT

[Daniel Tschlatscher]

This improves handling when two archive remove calls are creating a
race condition where one would formerly encounter an error. Now both
finish successfully.

[pve-devel] [PATCH storage v3 4/4] Added a LOG_EXT constant as a counterpart to NOTES_EXT

[Daniel Tschlatscher]

and refactored usages for .log and .notes with them.
At some parts in the test case code I had to source new variables to
shorten the line length to not exceed the 100 column line limit.

the "changes since v2" sections are missing from all patches, making it
harder to check if all comments got addressed or what other changes there
were...

Sorry for that, the changes from v2 are:

- Test cases are now part of the initial commit to make it compilable by 
itself.

- File 'unlink' now checks whether the file is already gone to avoid 
errors when removals are racing

- The code to 'unlink' the files was made a bit more concise and DRY by 
utilizing a loop

- Instead of plain 'warn' now use 'log_warn()'

- The file extensions for '.notes' and '.log' files now use constants 
declared in 'PVE::Storage::Plugin'
