I'm using latexmk for compilation of my document and want to limit time for every compile cycle. In order to do it I use
timeout util in following way:
latexmk -f -pdf -bibtex \ -pdflatex="timeout 5s xelatex -interaction=nonstopmode -synctex=-1 %O %S" \ main.tex
When a compile cycle takes more than 5s then TERM signal is being sent and the cycle is being killed. But the return code is 31744 as reported by latexmk:
Collected error summary (may duplicate other messages): pdflatex: Command for 'pdflatex' gave return code 31744
timeout util says that it should be 124:
If the command times out ... then exit with status 124
I took a look at latexmk source and the exit code it's talking about is captured from the provided command run (in my case it's
timeout 5s xelatex...)
I had an idea that it's because pdflatex catches SIGTERM and tried using SIGKILL in timeout command
timeout --signal=SIGKILL 5s... but there were exit code 35072.
So, my question is what are these strange exit codes? Where do they come from and what do they mean? I took a look at pdftex and xetex sources but found no mentions of them. Can I be sure that 31744 exit code means SIGTERM and nothing else?
A short note about the software I'm using:
- latexmk 4.39
- XeTeX, Version 3.1415926-2.5-0.9999.3 (TeX Live 2013/Debian)
- timeout from GNU coreutils 8.23
Thank you for any help.
