19975 2008-07-10 13:37:11 -0700 [OpenBSD] Patches to enable build of WebKit 2008-07-18 08:33:26 -0700 1 1 1 Unclassified WebKit Platform 528+ (Nightly build) PC Other RESOLVED FIXED P2 Normal --- 1 landry webkit-unassigned ddkilzer mrowe oldest_to_newest 85633 0 landry 2008-07-10 13:37:11 -0700 The following patches enable support for OpenBSD, adapted from the first diff shown here : https://bugs.webkit.org/show_bug.cgi?id=19775 - One patch against JavaScriptCore/wtf/Platform.h to add PLATFORM support, both for OpenBSD and SPARC64. - One against JavaScriptCore/kjs/config.h to define USE_PTHREAD_NP. - One against JavaScriptCore/wtf/Threading.h to avoir using functions from libestdc++ 4.2, because otherwise makefiles have to be patched to link agaisnt -lestdc++ instead of -lstdc++ (which is libstdc++ 3.3 on OpenBSD) - One against JavaScriptCore/kjs/collector.cpp to be sure we include pthread.h besides pthread_np.h, and also an #elif fragment to get the stack base. There are other patches i'm not submitting for review because they #define isfinite to finite and implement signbit(), because these functions are in the process of beign added to OpenBSD's libm and will be soon here (maybe the incoming 4.4) With this patches webkit/gtklauncher/midori works fine on i386/amd64/macppc. Patches from bug #19775 are also needed to try to support sparc64, although i haven't been able to make webkit run without SIGBUS. Last question, our default gcc/g++ is 3.3.5, are there plans to make webkit build with those compilers or gcc 4.x is _required_ ? 85635 1 22203 landry 2008-07-10 13:38:54 -0700 Created attachment 22203 patches for OpenBSD This patches are in the progress of beign tested _again_, but the previous diff linked on #19775 was tested several times. 85667 2 22203 ddkilzer 2008-07-10 15:06:33 -0700 Comment on attachment 22203 patches for OpenBSD Great! r=me I forgot to mention in the original review (Bug 19775 Comment #14) that you also need a ChangeLog entry. http://webkit.org/coding/contributing.html I'll write one up unless you'd like to do it. 85769 3 22246 landry 2008-07-11 02:54:40 -0700 Created attachment 22246 new patch to correctly include pthread.h We don't have thread.h like solaris, so patch it this way. This was my mistake, rebuilding to make sure it's ok now. For the changelog entry, go ahead :) 85770 4 22203 ddkilzer 2008-07-11 03:35:00 -0700 Comment on attachment 22203 patches for OpenBSD Oops.

There's no need to include it here. The ChangeLog for the first patch is "free". Please create one using the prepare-ChangeLog script. Thanks! r- for above issues. 86203 6 22335 landry 2008-07-17 04:59:29 -0700 Created attachment 22335 patch against svn And here's a cleaner, simpler patchset against svn, works fine with midori & webkit-r35203. ChangeLogs entries are included. - i finally added a temporary signbit/isfinite implemetation in MathExtras.h, similar to what is done for Solaris. Once we'll have them in libm it shouldn't conflict. - finally, Thread.h patching is not necessary, we have to link with libstdc++-4.2 anyway (that'll be our only local patch against GNUMakefile.am, because on openbsd libstdc++ in /usr/lib is 3.3 version, libstdc++ 4.2 is installed in /usr/local/lib/libestdc++) - a non-intrusive patch for WebKitTools/DumpRenderTree/DumpRenderTree.h has been added to conditionally declare the method. I think there's a better way to handle it, but it compiles and runs fine this way. Having a HAVE_WCHAR detection could help maybe. - while here i kept the PLATFORM(SPARC64) definition, needed for the upcoming fix for alignment problem on sparc64. I hope this patchset is correct, and am just waiting for a new nightly build including it to import my port of webkit & midori in OpenBSD's ports-tree. The fix for sparc64 will be worked on afterwards. 86205 7 22203 ddkilzer 2008-07-17 05:09:01 -0700 Comment on attachment 22203 patches for OpenBSD Clearing review flag for obsolete patch. 86206 8 22335 ddkilzer 2008-07-17 05:20:45 -0700 Comment on attachment 22335 patch against svn r=me! Please include reference to the bug in future changelog entries. Thanks! 86336 9 ddkilzer 2008-07-18 08:33:26 -0700 Committed r35234 Note that I tweaked the whitespace in MathExtras.h to match the formatting of the PLATFORM(SOLARIS) section above it. Please file new bugs for additional or follow-up issues, and feel free to copy me on them.
