gtester is deprecated by upstream glib (see for example the announcement
at https://blog.gtk.org/2018/07/11/news-from-glib-2-58/) and it does
not support tests that call g_test_skip in some glib stable releases.

glib suggests instead using Automake's TAP support, which gtest itself
supports since version 2.38 (QEMU's minimum requirement is 2.40).
We do not support Automake, but we can use Automake's code to beautify
the TAP output.  I chose to use the Perl copy rather than the shell/awk
one, with some changes so that it can accept TAP through stdin, in order
to reuse Perl's TAP parsing package.  This also avoids duplicating the
parser between tap-driver.pl and tap-merge.pl.

* [Qemu-devel] [PULL 23/35] test: replace gtester with a TAP driver
  2018-12-19 15:18 [Qemu-devel] [PULL v2 00/35] Misc patches for 2018-12-18 Paolo Bonzini
@ 2018-12-19 15:19 ` Paolo Bonzini

From: Paolo Bonzini @ 2018-12-19 15:19 UTC (permalink / raw)
  To: qemu-devel

gtester is deprecated by upstream glib (see for example the announcement
at https://blog.gtk.org/2018/07/11/news-from-glib-2-58/) and it does
not support tests that call g_test_skip in some glib stable releases.

glib suggests instead using Automake's TAP support, which gtest itself
supports since version 2.38 (QEMU's minimum requirement is 2.40).
We do not support Automake, but we can use Automake's code to beautify
the TAP output.  I chose to use the Perl copy rather than the shell/awk
one, with some changes so that it can accept TAP through stdin, in order
to reuse Perl's TAP parsing package.  This also avoids duplicating the
parser between tap-driver.pl and tap-merge.pl.

* [Qemu-devel] [PULL 23/35] test: replace gtester with a TAP driver
  2018-12-21 12:36 [Qemu-devel] [PULL v4 00/35] Misc patches for 2018-12-21 Paolo Bonzini
@ 2018-12-21 12:36 ` Paolo Bonzini
  0 siblings, 0 replies; 11+ messages in thread
From: Paolo Bonzini @ 2018-12-21 12:36 UTC (permalink / raw)
  To: qemu-devel

gtester is deprecated by upstream glib (see for example the announcement
at https://blog.gtk.org/2018/07/11/news-from-glib-2-58/) and it does
not support tests that call g_test_skip in some glib stable releases.

glib suggests instead using Automake's TAP support, which gtest itself
supports since version 2.38 (QEMU's minimum requirement is 2.40).
We do not support Automake, but we can use Automake's code to beautify
the TAP output.  I chose to use the Perl copy rather than the shell/awk
one, with some changes so that it can accept TAP through stdin, in order
to reuse Perl's TAP parsing package.  This also avoids duplicating the
parser between tap-driver.pl and tap-merge.pl.

* [Qemu-devel] [PULL 23/35] test: replace gtester with a TAP driver
  2019-01-07 22:31 [Qemu-devel] [PULL v4 " Paolo Bonzini

From: Paolo Bonzini @ 2019-01-07 22:31 UTC (permalink / raw)
  To: qemu-devel

gtester is deprecated by upstream glib (see for example the announcement
at https://blog.gtk.org/2018/07/11/news-from-glib-2-58/) and it does
not support tests that call g_test_skip in some glib stable releases.

glib suggests instead using Automake's TAP support, which gtest itself
supports since version 2.38 (QEMU's minimum requirement is 2.40).
We do not support Automake, but we can use Automake's code to beautify
the TAP output.  I chose to use the Perl copy rather than the shell/awk
one, with some changes so that it can accept TAP through stdin, in order
to reuse Perl's TAP parsing package.  This also avoids duplicating the
parser between tap-driver.pl and tap-merge.pl.

* [Qemu-devel] [PULL 23/35] test: replace gtester with a TAP driver

From: Paolo Bonzini @ 2019-01-09 22:09 UTC (permalink / raw)
  To: qemu-devel; +Cc: Paolo Bonzini

gtester is deprecated by upstream glib (see for example the announcement
at https://blog.gtk.org/2018/07/11/news-from-glib-2-58/) and it does
not support tests that call g_test_skip in some glib stable releases.

glib suggests instead using Automake's TAP support, which gtest itself
supports since version 2.38 (QEMU's minimum requirement is 2.40).
We do not support Automake, but we can use Automake's code to beautify
the TAP output.  I chose to use the Perl copy rather than the shell/awk
one, with some changes so that it can accept TAP through stdin, in order
to reuse Perl's TAP parsing package.  This also avoids duplicating the
parser between tap-driver.pl and tap-merge.pl.

This almost all works fine (there are some annoying intermittents
which mean that most of my full test runs fail somewhere for some
reason, but they aren't issues with this pullreq as far as I can
see[*]), but...

This should work fine if you retry this PR after having merged Fam's PR
which contains the fix.

I guess Travis is using a cached image.

Cool. I will do that and retry.

I'm not using travis, this is a local run of the test.
But perhaps my system has a cached image. It seems a bit
odd that it uses that cached image when testing master
but not when testing Paolo's merge, though.

The patch "test: replace gtester with a TAP driver" contains docker
changes (adding libtest-harness-perl) which trigger a rebuild, your
builds using /master should use the cache.

This might be a problem with this new package (if so, Fam's PR isn't
going to help here).

I'll check and if possible improve the docker.py output to get a more
useful error message.

Regards,

Phil.

Yes, in some versions of Debian it's a virtual package.  I should just
install perl instead.
