I think the change to the dump-post.pl script in http://trac.webkit.org/changeset/80428 caused the breakage: http://build.webkit.org/builders/SnowLeopard%20Intel%20Release%20%28Tests%29/builds/26369 http://build.webkit.org/results/SnowLeopard%20Intel%20Release%20(Tests)/r80428%20(26370)/results.html http://build.webkit.org/results/SnowLeopard%20Intel%20Release%20(Tests)/r80429%20(26371)/http/tests/plugins/post-url-file-pretty-diff.html http://build.webkit.org/results/Windows%207%20Release%20(Tests)/r80428%20(10099)/results.html http://build.webkit.org/results/Windows%20XP%20Debug%20(Tests)/r80428%20(26041)/results.html I am not sure what the right thing is to do here, but if this stays unaddressed for too long I will just commit the failing results or roll-out the change.
The patch was rolled out here: http://trac.webkit.org/changeset/80430 Sorry for the mess. Looks like there is some incompatibility here. I'll try to find a method that works on both Snow Leopard and my version of Linux on Monday.
