As well, one advantage we do have here from the chamelium end is

you can only really be screen grabbing from one port at a time. So

could actually just track stuff internally in the igt_chamelium

and when a user tries to download a framedump that we've already
downloaded, we can just hand them back a cached copy of it.
I forgot to answer this point. I think this bring way too much
overhead
and is not really necessary anyway. With the solution I proposed in
my
previous email on this thread, the two wrapper functions (one for
CRC,
one for analogue frame comparison) will either dump the frame for
CRC
comparison (because it was never dumped before) or use the provided
one
for analogue comparison, so there is no particular need to track
what
was or wasn't dumped before.
No need to track, just encode it in the filename:
$test-$subtest-error-crc-$crc.png
Just do not override existing files, and you are done :)
I suppose it would be best to have predictible filenames (so not
including the crc) to make it easier to grab the frame for an automated
testing framework, right? >
So what about: frame-$test-$subtest-$qualifier.png, with $qualifier
being either "reference" or "dump". I don't think it's necessary to
indicate whether the error comes from crc or analogue frame testing:
this will already be contained in the subtest name.
Well, predictable is actually problematic, since automated systems try
to reproduce issues, and your idea will lead to overriding (which is
only not a problem if the CRC is the same).
In the end, what we want is to say in the logs what are the files
(reference and dump). We'll need to agree on a format, so as an
automated system can pick it up :)
