So, I have been doing some progress on this thing.. And wrote the
patch attached that improves the way TAP tests log their output using
IPC::Run::run. This simply creates a log file as regress_log/test_name
for each test run, capturing all the command outputs. For example on
current HEAD, some commands of pg_ctl are simply silenced or have
their output redirected to /dev/null. With this patch, all their
output is redirected to the log file. This is as well compatible with
Windows, and logging of pg_rewind tests is unified with the new
structure of TestLib.pm. I am going to apply that to hamster and see
what is causing the error reported.
I think that it would be useful as well to improve the buildfarm
output. Thoughts?
