Package: lintian Version: 2.5.54 Severity: normal Hi,
Lintian is unreliable at handling signals. This causes it to fail to clean up in some cases on lindsay.d.o (and other archive-wide runs). Example from the log file: """ [2017-10-14T03:34:39]: Updating harness state cache [2017-10-14T03:34:55]: Running Lintian (round 4/16) ... [2017-10-14T03:34:55]: - Range: GROUP:2vcard/0.6-1 ...

[2017-10-14T04:01:24]: Lintian terminated by signal: 15 [2017-10-14T04:01:24]: - skipping the rest of the worklist """ This log suggests that lintian continued despite having received a signal. Furthermore, there is a left over temporarily lab on lindsay.d.o having a timestamp close to start of the lintian run: """ $ ls -ld /srv/lintian.debian.org/scratch/temp-lintian-lab-rCsPnScQ8t drwx------ 4 lintian lintian 4096 Oct 14 03:34 /srv/lintian.debian.org/scratch/temp-lintian-lab-rCsPnScQ8t """ My /guess/ is that when lintian received the first signal, the signal handler then disabled itself and threw a "Interrupted" error. Something then catches the error and flags the check / package as "uncheckable" but continues on. When the second signal arrived, the default signal handler terminated with lintian not cleaning up after itself. Thanks, ~Niels
