Обсуждение: -HEAD on FreeBSD 6-CURRENT build failures
There looks to be an issue with gram.y as seen in the following 2 FreeBSD6 boxen: http://pgbuildfarm.org/cgi-bin/show_log.pl?nm=herring&dt=2005-01-28%2018:33:43 http://pgbuildfarm.org/cgi-bin/show_log.pl?nm=echidna&dt=2005-01-28%2018:30:01 -- Darcy Buskermolen Wavefire Technologies Corp. ph: 250.717.0200 fx: 250.763.1759 http://www.wavefire.com

The impression I have gained from watching the build farm is that ccache is seriously unreliable --- the machines using it often show transient build failures that look like failure to update derived files. regards, tom lane

We don't even bot6her with clean, distclean, maintainer-clean and friends - we simply copy the source directory tree for each run. The fact that Darcy's builds don't show a call to bison indicates to me that his source dir ( /buildfarm/pg-buildfarm/HEAD/pgsql ) might not be clean for some reason that is not clear to me. Darcy, please blow that directory tree away and see if the situation recovers. cheers andrew

Hmm, source directory used for a build and then not maintainer-clean'd
perhaps?
If you do the copy without -p then the copy would tend to lose the
timestamps that would show that the gram.c file is out of date.
I suppose "cp -p" would be a bad idea because of permissions issues,
but you could consider replacing the cp with "tar cf - | tar xf -"
to preserve timestamps better.

Basically the user should not touch anything inside <buildroot>, any more that they should touch anything in <datadir>/base. >If you do the copy without -p then the copy would tend to lose the >timestamps that would show that the gram.c file is out of date. >I suppose "cp -p" would be a bad idea because of permissions issues, >but you could consider replacing the cp with "tar cf - | tar xf -" >to preserve timestamps better. > > > > If we needed to, yes. rsync also works very nicely on stuff like this - and I have been using it in my day job for such a purpose. But I think the answer in this case is "don't do that." Darcy has cleaned out his source directory and all now seems well. cheers andrew
