Hello guys,
Is there's a way how to set requested amount of ram for koji builders?
I'd like to use it as Firefox builds fail recently due low memory, like
https://bugzilla.redhat.com/show_bug.cgi?id=2241690
<https://bugzilla.redhat.com/show_bug.cgi?id=2241690>
I looked at the first linked build log in the ticket and it looks like
the build failed in the debuginfo extraction step. In that log,
find-debuginfo is called with -j3, and it could be that it ran out of
memory because it was trying to do 3 debuginfo extractions in parallel.
You could try to stick something like this in the spec file to tune it down:
# Require 32 GB of RAM per CPU core for debuginfo processing
%global _find_debuginfo_opts %limit_build -m 32768
... and see if it helps. With this, it should pass -j1 to find-debuginfo
when the builder has 32 GB RAM, -j2 when it has 64 GB etc.
If that doesn't work, then there's also the option of using -g1 to
reduce the binary sizes so they take less memory to process (but that
makes backtraces much worse so I'd only leave it for emergencies if you
can't get an important build out otherwise).
Does a hammer smaller than -g1 also exist for issues like:
relocation truncated to fit: R_X86_64_32 against `.debug_info'

Thanks for the info in advance.
Best regards,
Julian
