Subject: obsolete conffiles not removed on upgrades

Date: Wed, 19 Oct 2011 05:53:55 +0200

Package: console-setup
Version: 1.73
Severity: important

While doing a test-upgrade from squeeze to sid, the following conffiles
were not cleaned up during the upgrade and marked as obsolete in the
dpkg status file:

The conffiles are not obsoleted, now they belong to another package - 
console-setup-linux. I am sure this is not the first time conffiles have 
been transferred from one Debian package to another, but I don't know 
what is the proper way to handle this. I suppose this bug belongs to 
dpkg, should I reassign?

Well, dpkg certainly handles conffiles moving from one package to the
other if you use the proper "Replaces" field like for any other file.

Michael, what does your system say for "dpkg -S
/etc/console-setup/remap.inc" ?

I think it will give the new package. And the file will only appear in
dpkg -L of the new package too. However it's true that the "Conffiles"
field is not always properly updated. The conffile often ends up being
listed on both packages.

I instrumented the "t-conffile-replaces" test case like this:
--- a/t-conffile-replaces/Makefile
+++ b/t-conffile-replaces/Makefile
@@ -9,6 +9,9 @@ define VERIFY
 test "`$(PKG_STATUS) pkg-conff-original`" = "install ok installed"
 test "`$(PKG_STATUS) pkg-conff-takeover`" = "install ok installed"
 test "`$(DPKG_QUERY) -S /test-conffile`" = "pkg-conff-takeover: /test-conffile"
+$(DPKG_QUERY) -W -f'$${Conffiles}\n' pkg-conff-original
+echo "Takeover:"
+$(DPKG_QUERY) -W -f'$${Conffiles}\n' pkg-conff-takeover
 cmp ref-conffile /test-conffile
 endef

It gives various results depending on how dpkg is called:
test-two-run-ordered & test-two-run-reverse:
 /test-conffile e8a2f071ccdf836fc77865fba3ee8558
Takeover:
 /test-conffile 45a18cfae67be6e80a5ec2ee60579bf3

test-one-run-ordered:
 /test-conffile 45a18cfae67be6e80a5ec2ee60579bf3
Takeover:
 /test-conffile newconffile

test-one-run-reverse:
 /test-conffile newconffile
Takeover:
 /test-conffile 45a18cfae67be6e80a5ec2ee60579bf3

There's room for improvements here.

Currently console-setup-linux doesn't "Replace" console-setup.

If this was the real cause of the problem, then perhaps the bug can be 
reassigned back to console-setup? Regardless of the reassigning, thanks 
for the hint!  I will change this in the next version of console-setup.

But it conflicts with old version of it, so it's enough to take over
the conffile since at no point in time is the conffile owned by 2
packages.

An obsolete conffile can always be taken over without any explicit
Replaces field.

There's no real bug except the fact that the files are listed in the
Conffiles field of two packages at the same time. So I'll keep this bug
on dpkg.
