Package: lintian
Version: 2.116.3
Severity: important
Tags: ftbfs
While running Lintian's testsuite on a much faster system compared to
my Sid amd64 running development workstation, I noticed the following
test suite failure when running "private/runtests" or trying to build
the package on a more modern and more performant box with Bookworm
amd64. (Use "private/runtests -o test:ancient-source" to just run the
affected test.)

# at /home/abe/debian/lintian/lib/Test/Lintian/Run.pm line 343.
# Looks like you failed 1 test of 1.
But I neither get that failure on my Sid amd64 development workstation
nor on SalsaCI (https://salsa.debian.org/lintian/lintian/-/pipelines)
nor in pbuilder nor on the buildd
(https://buildd.debian.org/status/package.php?p=lintian).
So I tried to find differences.
$ als debian/test-out/packages/checks/unpack/ancient-source/ancient-source_1.0.orig.tar.gz ancient-source-1.0/README
-rw-r--r-- root/root 21 1970-01-01 00:59 ancient-source-1.0/README
$ env TZ=GMT als debian/test-out/packages/checks/unpack/ancient-source/ancient-source_1.0.orig.tar.gz ancient-source-1.0/README
-rw-r--r-- root/root 21 1969-12-31 23:59 ancient-source-1.0/README
But these two outputs are identical on both hosts, the one where the
test fails and one of those where it doesn't fail. So the timestamp
actually seems to be the same and it's just Lintian's parsing of it
seems to differ.
The only potentially relevant package version difference I found was
tar, which is at 1.34+dfsg-1.1 in Sid and 1.34+dfsg-1 in Bookworm due
to a recent FTBFS on 32-bit architectures. But the sole change was in
debian/copyright and also downgrading the tar version in Sid to the
one from Bookworm didn't make the test failing on Sid.
Also running the test suite with "env TZ=GMT" prepended didn't make a
difference.
Additionally, build 2.116.2 did work on that very same box where
2.116.3 now FTBFS. So it seems to have caused been a recent change
(since 2023-01-29) in Bookworm. Or maybe such a change just uncovered
an older bug.
The locales of two systems where it builds and where it no more
builds:
Builds fine:
LANG=C.UTF-8
LANGUAGE=
LC_CTYPE="C.UTF-8"
LC_NUMERIC="C.UTF-8"
LC_TIME="C.UTF-8"
LC_COLLATE="C.UTF-8"
LC_MONETARY="C.UTF-8"
LC_MESSAGES="C.UTF-8"
LC_PAPER="C.UTF-8"
LC_NAME="C.UTF-8"
LC_ADDRESS="C.UTF-8"
LC_TELEPHONE="C.UTF-8"
LC_MEASUREMENT="C.UTF-8"
LC_IDENTIFICATION="C.UTF-8"
LC_ALL=
No more builds fine (but hasn't change since when it still built
fine):
LANG=C
LANGUAGE=
LC_CTYPE="C"
LC_NUMERIC="C"
LC_TIME="C"
LC_COLLATE="C"
LC_MONETARY="C"
LC_MESSAGES="C"
LC_PAPER="C"
LC_NAME="C"
LC_ADDRESS="C"
LC_TELEPHONE="C"
LC_MEASUREMENT="C"
LC_IDENTIFICATION="C"
LC_ALL=
Also both systems have "Europe/Zurich" in their /etc/timezone.
So I currently have no idea where the difference comes from or which
environmental change (variables or package versions) triggers
it. Cc'ing the Reproducible Builds project in the hope that they have
an idea what could have caused the 1h offset in the testsuite on that
one box.
