--- Comment #2 from Buovjaga <ilmari.lauhakan...@libreoffice.org> ---
This seems difficult to bisect.
I adapted a script from
https://wiki.documentfoundation.org/QA/Bibisect/Automation like this:
#!/usr/bin/env bash
# bisect_perf.sh Called with 3+1 parameters: "file.ext" good-time timeout-time
[fix]
fileext=$1 ; goodtime=$2 ; timeouttime=$3 ; regfix=$4
if [[ $regfix = "fix" ]]; then before=1; after=0; else before=0; after=1;
fi
# timeout takes seconds by default
timeout $timeouttime bash -c ' OOO_EXIT_POST_STARTUP=1
SAL_USE_VCLPLUGIN=gen ./instdir/program/soffice --norestore "$@" ' bash
/home/user/libobugs/"$fileext"
status=$? ; echo "$status"
exptime=$SECONDS
if [ $status = 124 ] ; then
echo "timeout in $timeouttime, done in $exptime sec" ; exit
$before
elif [ $status = 134 ] ; then
echo "done in $exptime sec" ; exit $after
elif [ $status = 42 ] ; then
if (( $exptime < $goodtime )) ; then
echo "opens fast in $exptime sec" ; exit $before
elif (( $exptime > $goodtime )) ; then
echo "opens slow in $exptime sec" ; exit $after
else echo "error"
fi
else echo "other exit code"
git reset --hard
fi
Then started a run with it in the Linux 24.2 repo, which seemed to be the one
where it slowed down:
git bisect start master oldest && git bisect run /path/to/bisect_perf.sh
"Тест.xlsx" 80 240
Limit for good being 80 secs and timeout being 4 minutes. However, the results
were not reliable in the actual bisecting run. The original bad time I saw was
like 2min30sec, but in the bisect run I got many timeouts, so going over 4
mins. Doing the run a couple of times and checking the blamed vs. previous
commit revealed the result was incorrect.
I may continue investigating this.
