Description

As Alexey mentioned at the scrum today, compile-cache in ldv-git is a powerful optimization, but sometimes the user needs to clean it (for example, after bugs like #718 are fixed). An interface like ldv-git drop-cache would be nice.

Another nice feature would be ldv-git drop-older-caches, which is intended to dropping caches of commits that are older than the current one. Useful if the user knows that he's not going to re-check them anymore.

Всё бы хорошо, только prefix=/opt make install почему-то не обновляет ldv-git.

After installation the new version using make install-ldv-git, ldv-git drop-cache and running ldv-git --force --no-update-meta --keep-work --rule=08_1 --filter=isdn/capi/capidrv check, I have got the following error:

The metadata file in /home/tester/ldv/workdir/envs/1/metadata/meta-4162cf64973df51fc885825bc9ca4d055891c49f doesn't exist.

LDV-Git's cache cleanup procedure has nothing to do with it. It doesn't touch such files.

However, I compared the path with the path I saw in bug #718, and noticed that they differ...

/home/tester/.ldv/ldv/envs/1/work/work-4162cf6
/home/tester/ldv/workdir/envs/1/metadata/meta-4162cf6

Did you fiddle with LDVGIT_BASE environment variable?

ldv-git drop-cache and ldv-git drop-older-caches works, the only open issue is some old caches are not removed by ldv-git --rule=all drop-older-caches.

They now do. See revision 87223b3.

I already have no environment to check the fix, so I suggest to call it fixed and open a new bug if any issues arose.
