Since a couple of days, our workers on s390x are dying because some test
is filling up all disk space. Several days ago, I wrongly suspected
One of the suspects started to be spirv-llvm-translator-14, so I ran its autopkgtest manually, while logging disk use every 10 seconds (I started slightly delayed because I monitored the wrong partition first). As you
can see below, during the test it grows from 17 GB (at the end) to its
peak at 179 GB. That's not acceptable on our infrastructure. One file I happened to spot on the way was build/test/test_output/DebugInfo/Generic/Output/two-cus-from-same-file.ll.tmp:
-rw-r--r-- 1 root root 41G Mar 3 19:18 two-cus-from-same-file.ll.tmp
I have added spirv-llvm-translator-14 to our reject-list on s390x.
As this seems to be a rather new issue, I'm wondering if it's due to:
* Add build-needed autopkgtest for spirv-headers compat check.
Probably.
The buildds report disk usage when building spirv-llvm-translator-*
between 400MB and 600MB on all architectures except s390x, ppc64,
sparc64, i.e. all the big-endian ones, where it's slightly above 40GB
(which very vell corresponds to the file you spotted).
This started with 14.0.0-2 (i.e. 14.0.0-1 was around 500MB on s390x,
too) which had "* Enable build-time tests, ignore failures on !amd64."
So maybe I should skip the build-time tests on big-endian altogether.
Failure rates:
amd64: 0%
i386: <1%
ppc64el: <2%
most: <10%
s390x: >60%
ppc64: >60%
(Upstream seems to test the testsuite only on amd64,
