build-webkit --32-bit failed for me on my Lion box just now, making it difficult to test if this mode works. Gavin, do you have suggestions as to how I should test run-webkit-tests --32-bit?

Help? I need assistance from someone who has used this configuration. Otherwise I can only guess at what we might need for support here.

Hi Eric, Apologies, I'm terribly sorry for the slow response on this one. ORWT can be used to test 32-bit on a 64-bit machine using the following steps: build-webkit --debug ARCHS=i386 export VERSIONER_PERL_PREFER_32_BIT=yes old-run-webkit-tests --debug --32-bit [ The second step (the export) is really a workaround for a bug. As I understand it, one of the perl scripts compiles & loads a couple of modules, and these really should be being compiled based on the platform you are running on alone (since perl runs in 64-bit by default, the module should be compiled as 64-bit). Currently however the modules are instead being compiled for the platform you are testing, in this case 32-bit. ] Hope this helps! many thanks, G.

Thanks!

Okay, so now I'm looking at what we might need to implement here in NRWT. From, looking at the code, the only things I can see is that --32-bit might need to be propagated to the call to build-dumprendertree, and possibly we would need to *not* skip plugins/npp-set-window-called-during-destruction.html: http://trac.webkit.org/browser/trunk/Tools/Scripts/old-run-webkit-tests#L1425 http://trac.webkit.org/browser/trunk/Tools/Scripts/old-run-webkit-tests#L610 Can someone confirm that's correct? I'll add a patch for this and that can be reviewed ...

Comment on attachment 146961 [details] Patch Code all looks fine. Someone at Apple may want to verify that this is what they were asking for.

I ran this on Mac Lion and it seemed to do the right thing; I'll give the apple guys a chance to take a look but plan on landing this tomorrow unless I get a negative review.

Hi Dirk, Thank you for fixing this! – I'm away from my desk for a couple of days, so I wouldn't be able to help test this until Thursday – please feel free to go ahead and land if it is working for you. Thank you!, Gavin.
