Possible dpkg regression
Hi Guillem,
I was about to file a bug against clang-3.3 but what I discovered looked
like more a bug in dpkg. It's probably related to the recent optimizations
that concerns management of file lists.
In today's dist-upgrade:
Unpacking llvm-3.3 (1:3.3-13) over (1:3.3-12) ...
Preparing to unpack .../clang-3.3_1%3a3.3-13_amd64.deb ...

Unpacking libllvm3.3:i386 (1:3.3-13) over (1:3.3-12) ...
(This is the french string for a file conflict detected by dpkg)
Strangely, the next "apt-get -f install" fixed it even though llvm-3.3 had
already been unpacked and thus nothing was supposed to change.
Preparing to unpack .../clang-3.3_1%3a3.3-13_amd64.deb ...

$ dpkg -c /var/cache/apt/archives/llvm-3.3_1%3a3.3-13_amd64.deb |grep c-index-test
$ dpkg -c /var/cache/apt/archives/llvm-3.3_1%3a3.3-12_amd64.deb |grep c-index-test
-rwxr-xr-x root/root 87256 2013-10-29 19:46 ./usr/lib/llvm-3.3/bin/c-index-test
lrwxrwxrwx root/root 0 2013-10-29 19:45 ./usr/bin/c-index-test-3.3 -> ../lib/llvm-3.3/bin/c-index-test
$ dpkg -c /var/cache/apt/archives/clang-3.3_1%3a3.3-12_amd64.deb |grep c-index-test
$ dpkg -c /var/cache/apt/archives/clang-3.3_1%3a3.3-13_amd64.deb |grep c-index-test
-rwxr-xr-x root/root 87256 2013-11-05 15:07 ./usr/lib/llvm-3.3/bin/c-index-test
lrwxrwxrwx root/root 0 2013-11-05 15:06 ./usr/bin/c-index-test-3.3 -> ../lib/llvm-3.3/bin/c-index-test
But clang-3.3 1:2.3-13 has an appropriate Replaces already "llvm-3.3 (<<
1:3.3-13)". It also has the same Breaks (not Conflicts). AFAIK the
Replaces alone should have been more than enough, here it looks like that
dpkg has kept ./usr/lib/llvm-3.3/bin/c-index-test associated to llvm-3.3
even though that package has been upgraded. The next dpkg run fixed this
(possibly because it reloaded the file list from the disk instead).
I have created a minimal test case for this, it's attached and I can
reproduce the problem with it:
# test-one-run-ordered
sudo env dpkg --admindir=/home/rhertzog/deb/core/pkg-tests/t-file-replaces-versioned/../dpkgdb --force-unsafe-io --no-debsig -i pkg-file-original-0.deb pkg-file-takeover-0.deb

Subject: [PATCH] New t-file-replaces-versioned test case
This one checks moving a file from package A to B when a A/0 and B/0
are both initially installed. B/1 has a replaces on A (<< 1) to avoid
the file conflict.
