there is no clue on why "SLES-12-SP5-x86_64-mru-install-minimal-with-addons-Build:16741:php7-Server-DVD-Incidents-64bit.qcow2" could not be downloaded, from where to where it should have been downloaded, etc. There is no http status code or anything, like no "404 Not Found" or similar.
Acceptance criteria¶
- AC1: The real reason for the download error is accessible in the job details (either "reason" or autoinst-log.txt), e.g. http status code with message
Suggestions¶
- Research what the actual error could be and add it as a "likely explanation" in the existing error string
- Try to include the actual error details into the affected jobs logs
- If possible, adapt the "reason" to be more specific with details about the actual error

According to the log message, there is no output and error message. We could see that from
https://github.com/os-autoinst/openQA/blob/master/lib/OpenQA/Worker/Engines/isotovideo.pm#L156
my $msg = "Download of $asset_uri processed";
if (my $output = $status->output) { $msg .= ":\n$output" }
log_info($msg, channels => 'autoinst');
$asset = $cache_client->asset_path($webui_host, $asset_uri)
if $cache_client->asset_exists($webui_host, $asset_uri);
... ...
if (!$asset) {
$error = "Failed to download $asset_uri to " . $cache_client->asset_path($webui_host, $asset_uri);
... ...
}
Maybe we could add the $status->result in this log message to see if the result is empty too.
Since the code has set the result:
https://github.com/os-autoinst/openQA/blob/master/lib/OpenQA/CacheService/Controller/API.pm#L38
if ($info->{state} eq 'finished' && !$self->progress->is_downloading($info->{notes}{lock})) {
$status = {status => 'processed', result => $info->{result}, output => $info->{notes}{output}};
I have not found a way to reproduce this issue.

Apparently there's not error to be reported from the view of the cache service but the asset isn't there after all. Without further information it looks like the asset might have been purged in the meantime. That's what the check @okurz added is supposed to catch. However, I've already noted back then that it will not work in all cases.

- Related to action #71827: test incompletes with auto_review:"(?s)Failed to download.*Asset was pruned immediately after download":retry because worker cache prunes the asset it just downloaded added

Do you mean that the specific example from the specific example above is not there right now? If this is the case it could certainly have been there at the time of ticket reporting. Or did you mean something different?

which we probably would see in logs

Right. It could be that the cache service knows that the asset was pruned but that this was not reported in the job in question here.
Well, as it could be that this is the same root problem as in #71827 we can also wait for that one first

Yes, I mean the example from the ticket description. In this example the log message Failed to download… is present. That means the cache service did not report an error because otherwise this error would have been logged and the line generic Failed to download… line not being logged. The generic line is only logged if the cache service reported no error but despite that the file isn't there.
which we probably would see in logs
That's what I mean with "without further information". I haven't looked into the cache service log yet. I suppose the worker log (which is the only log mentioned in the ticket) would not necessarily mention if the asset was purged. (It could have been purged to make room for a completely different asset which has been requested concurrently.)

With #71827 I checked if we have further references to this ticket using openqa-query-for-job-label poo#73285 and have found no references so likely we are done here as well
