Also (or alternatively), it should probably only happen when we are in verbose mode (it's not taken care of for us as usual because tests call start_httpd outside of a test_expect_ block). I think this eliminates the need to deal with the TAP thing (because our usual "-v" output is not TAP-compliant). -Peff ``` ## Duy Nguyen, 2016-06-13 11:40 Subject: Re: [PATCH] lib-httpd.sh: print error.log on error Message-ID: <20160613114014.GA15562@ash> URL: https://gitlist.dev/e/20160613114014.GA15562%40ash In-Reply-To: <20160612125921.GA15289@sigill.intra.peff.net> ``` On Sun, Jun 12, 2016 at 08:59:21AM -0400, Jeff King wrote: > On Sun, Jun 12, 2016 at 05:41:54PM +0700, Nguyễn Thái Ngọc Duy wrote: > > > Failure to bring up httpd for testing is not considered an error, so the > > trash directory, which contains this error.log file, is removed and we > > don't know what made httpd fail to start.

(I had originally thought that we set up those fds only inside the test_expect blocks, but it is the redirection 2>&4 that we set up there; you can always use fd 4 as necessary). It does incur a useless "cat" when we are not verbose, but I don't think that's a big deal for the error path like this. -Peff ``` ## Nguyễn Thái Ngọc Duy, 2016-06-13 12:35 Subject: [PATCH v3] lib-httpd.sh: print error.log on error Message-ID: <20160613123509.22412-1-pclouds@gmail.com> URL: https://gitlist.dev/e/20160613123509.22412-1-pclouds%40gmail.com In-Reply-To: <20160613115608.GA5652@sigill.intra.peff.net> ``` Failure to bring up httpd for testing is not considered an error, so the trash directory, which contains this error.log file, is removed and we don't know what made httpd fail to start.
