How big is the file? It must not be bigger than UPLOAD_MAX_MESSAGE_SIZE_GB which is by default 20 GiB.

mkittler no idea how big it is, maybe already big then default value, so my understanding i can set UPLOAD_MAX_MESSAGE_SIZE_GB = 30 for a clone job?

Yes, setting UPLOAD_MAX_MESSAGE_SIZE_GB to a bigger value (e.g. via `openqa-clone-job´) than the actual file size should work. Considering the default is already quite big I'm nevertheless wondering whether it would make more sense trying to keep the file smaller.

base http://openqa.suse.de/tests/8349502#live result, it seems UPLOAD_MAX_MESSAGE_SIZE_GB can not take effect, i set it to 50, but qcow size is 24 but still see "too big" msg.

This should have been working - the value is also in vars.json and I don't see a local override via MOJO_MAX_MESSAGE_SIZE.

Btw, that's the code responsible for setting the limit: https://github.com/os-autoinst/os-autoinst/blob/9baeb0bfe086b40dec131d78a5f5b29778fac8c5/commands.pm#L228

I only saw that the job is incomplete, where did you see the message about "too big"?

the above job not capture the last screen since incomplete.
see this job.

BTW: when this PR will implement in osd so i can have a try?

It has been deployed as of 24.03.22 06:28 CET.

I wonder if this should be blocking on #109046 since the tests can't be verified?

base following case result, the issue still happen, since i saw the PR set default value to infinity so i SKIP the setting of UPLOAD_MAX_MESSAGE_SIZE_GB, but error msg "Maximum message size exceeded"

It works for me locally via:

truncate -s 30G t/data/big-file
curl --progress-bar --form upload=@t/data/big-file --form target=assets_public http://localhost:49019/Hallo/upload_asset/foo
OK: foo

On http://localhost:49019 a test command server is running.

Note that temporary files end up (by default) under /tmp so this directory needs to be big enough. Of course the pool directory needs to be big enough as well. Maybe it makes most sense to have the temporary directory somewhere within the pool directory so the final move is just a move within the same file system and we don't risk using too much RAM (since /tmp is often tmpfs).

If I give it a too small temp dir¹ the command server gets just stuck writing the file and shows increasing memory usage (up to 2 GiB) until it finally resets the connection:

curl --progress-bar --form upload=@t/data/big-file --form target=assets_public http://localhost:50263/Hallo/upload_asset/foo
curl: (56) Recv failure: Die Verbindung wurde vom Kommunikationspartner zurückgesetzt

Far from ideal but not really the issue I wanted to reproduce.

By the way, when giving the command server a MOJO_TMPDIR it cannot write to at all (e.g. I've tried /dev/full and a directory where it has no permissions) then it seems to stick to an in-memory asset. At least the memory usage increased so fast on my system that I had to stop the processes before running out of memory.

¹ e.g.

dd if=/dev/zero of=tmp-1gib bs=1M count=1024
/usr/sbin/mkfs.ext4 tmp-1gib
mkdir tmp-1gib.d
sudo mount -o loop tmp-1gib tmp-1gib.d
sudo chown martchus:users tmp-1gib.d
export MOJO_TMPDIR=tmp-1gib.d

A PR to avoid relying on /tmp being big enough: https://github.com/os-autoinst/os-autoinst/pull/2009

But judging from my experiments it won't help with this issue (which I still couldn't reproduce).

Tried to replicate the issue with a small Mojolicious unit test, but have been unable to unfortunately. The underlying Mojo::Asset::* modules throw an exception. https://github.com/mojolicious/mojo/commit/3ea094e3073f8e4d72adbc0d47fb3505b96e90a9

The mentioned PR has been merged and is expected to be deployed on Monday morning (CEST).

I did manage to fix the memory leak in Mojolicious though. So memory usage should not be able to exceed the limit anymore. https://github.com/mojolicious/mojo/commit/ba9d3c2bceb9b1524e1ce07994b33da5ea9b8ce0

https://github.com/os-autoinst/openQA/pull/4586 is deployed on OSD. I triggered https://openqa.suse.de/tests/8463395# in the scenario "sle-15-SP4-Continuous-Migration-SLE15SP4-s390x-offline_sle12sp3_sles15sp3_sles15sp4_media_all_full_s390x_ph0@s390x-kvm-sle15" which previously failed. Let's see the effect.
