It seems that at some point some modifications were made to the malloc implementation, and the new code was under the WTF_CHANGES flag. At some point things switched around so that old code was under #ifndef WTF_CHANGES. That old code does not appear to be used on any platform. This patch to be attached removes the define and related unused code. 478442 1 109812 wingo 2011-10-05 09:49:37 -0700 Created attachment 109812 Patch 478444 2 webkit.review.bot 2011-10-05 09:51:51 -0700 Attachment 109812 did not pass style-queue: Failed to run "['Tools/Scripts/check-webkit-style', '--diff-files', u'Source/JavaScriptCore/ChangeLog', u'Source..." exit_code: 1 Source/JavaScriptCore/wtf/FastMalloc.cpp:3225: Weird number of spaces at line-start.

We should not remove it just because it’s always 1. If it has outlived its usefulness we could remove it, but that decision should be made by whoever is merging in new versions of TCMalloc. 478466 4 wingo 2011-10-05 10:13:58 -0700 (In reply to comment #3) > (From update of attachment 109812 [details]) > We created this define to help us track the original version of TCMalloc. We should not remove it just because it’s always 1. If it has outlived its usefulness we could remove it, but that decision should be made by whoever is merging in new versions of TCMalloc. Thank you for the review, Darin. The define is poorly named, however, and I wonder if it really needs to make it all the way out to JavaScriptCore/config.h. Also not all changes to tcmalloc are guarded by this flag. Do you think that there is something worth doing here or should we close this bug? 480964 5 wingo 2011-10-10 08:06:04 -0700 Adding Darin to cc to close. (I am new to WebKit, so if this is the wrong thing to do, please let me know.) 481147 6 darin 2011-10-10 14:13:52 -0700 (In reply to comment #4) > The define is poorly named, however I agree. > I wonder if it really needs to make it all the way out to JavaScriptCore/config.h.

Also a good point. > Do you think that there is something worth doing here or should we close this bug? I think it’s worth finding out if we are getting any value from having our changes wrapped in #if now. If we’re not, it might be nice to reduce the noise and complexity by removing this. I think the real question is who would know the answer to that. Who has recently dealt with comparing with the “real” TCMalloc or importing a new version of it into our source tree? I cc’d a few people who might know. 485005 7 wingo 2011-10-17 02:07:06 -0700 Thanks for the reply, Darin.
