And I have been able to spend the time I wanted to spend on this patch
series with testing for 9.3 to 9.5. Attached are a couple of patches
you can use to reproduce the failures for all the branches:
- For master and 10, the tests are included in the patch and are
proposed for commit.
- On 9.6, I had to tweak the TAP scripts as pg_ctl start has switched to
use the wait mode by default.
- On 9.5, there is a tweak to src/Makefile.global.in which cleans up
tmp_check, and a couple of GUCs not compatible.
- On 9.4, I had to tweak src/Makefile.global.in so as the temporary
installation path is correct. Again some GUCs had to be tweaked.
- On 9.3, there is no TAP infrastructure, so I tweaked
src/test/recovery/Makefile to be able to run the tests.
I have also created a bash script which emulates what the TAP test does,
which is attached. Because of visibly some timing reasons, I have not
been able to reproduce the problem with it. Anyway, running (and
actually sort of back-porting) the TAP suite so as the problematic test
case can be run is possible with the sets attached and shows the failure
so we can use that.
Thoughts? I would love more input about the patch concept.
