(I fixed the description to correct the directions)
Indeed this can happen. We don't support partial upgrades, so it's not
such a big deal (thus the bug priority), but it's a pathological case.
Question is whether we want to sacrifice a lot of disk space just to
support partial upgrades without losing some files, and I don't even
think that this happens often. Did you actually see this case in
practice?
** Description changed:
Binary package hint: cdbs
Hi,
cdbs should only place symlinks to a depending package in /usr/share/doc
in case there the same (for ubuntu: source)-version is specified.
consider the following
source pacakge pfoo builds A and B
A depends on B
- -> symlinks get created for /usr/share/doc/B/somefile -> ../A/somefile
+ -> symlinks get created for /usr/share/doc/A/somefile -> ../B/somefile
pfoo is a new version.
- A gets upgraded on a users system, B doesn't.
- The new A doesn't contain /usr/share/doc/A/somefile any longer.
+ B gets upgraded on a users system, A doesn't.
+ The new B doesn't contain /usr/share/doc/B/somefile any longer.
OTOH a >= dependency would equally fail:
- A stays the same on the users system, B gets updated
- the new A can contain a new doc entry someotherfile.
- hence the new B contains a symlink to ../A/someotherfile
- the old A on the users system doesn't containt that file.
+ B stays the same on the users system, A gets updated
+ the new B can contain a new doc entry someotherfile.
+ hence the new A contains a symlink to ../B/someotherfile
+ the old B on the users system doesn't containt that file.
This is an ubuntu only bug.
Cheers,
Stefan.
