Which is a slow and terrible user experience, yes changes like this
take time but the sane thing to do would be to disable the retrace
option and default to local processing until it's fixed.

Right. The issue is zstd. Retrace-server uses Mock to install packages. Previously, Mock on RHEL7 was unable to install 
Fedora 31 because of zstd. This changed in Mock 1.4.20 [1], which hit stable in EPEL only 10 days ago [2].

should be done soon as well.


We need to finish one of those tasks. Until then, the retrace of F31+ will fail.

I agree. While RHEL is part of the Fedora family, we can't really do
much for it. At least we'll eventually get zstd support in RHEL 8. I
suppose we could rebuild rpm with zstd support for the server before
then, since it's just a bcond away...

   This is a fallout of us not “dogfooding”, but running our infrastructure
on some other distributions.

I filed this awhile ago, but didn't pursue getting it disabled on the
Fedora side in the meantime. While I'm a fan of zstd, I think in hindsight
I'd have recommended postponing rolling out that change until a retrace
server solution was in place. I'd definitely say this should have been a
listed liability of the change to use zstd.

Maybe it'd be possible to swing a RHEL 8 system with the updated rpm
with zstd support? The RHEL bug[1] indicates that there's a build with
it enabled...

It's a problem on RHEL-8 too then.

Well we should probably disable the retrace and default to local on
the releases that it's a problem because it's not exactly fast and if
it's going to fail every time it's not exactly a fantastic experience
for the user, same goes if we don't support the architecture if it's
not supported for retrace.

Re: Issues with the retrace service?

Hi,

I think retrace service is running on RHEL 7.7 server and since we have
zstd rpms in Fedora 31 [0], it won't work. I don't know what's the ETA for
fix, I can ask on Tuesday, if there is any update on this issue.

Until then, you'll probably have to generate stack traces locally :/

Issues with the retrace service?

2019-10-26 Thread Peter Robinson
Hi all,

It seems with F-31 on x86_64 the retrace service seems to fail every
single time I try to submit a crash report, is there known issues with
the service?
