198065 2019-05-20 20:36:50 -0700 [YARR] Properly handle RegExp's that require large ParenContext space 2019-08-12 12:55:49 -0700 1 1 1 Unclassified WebKit JavaScriptCore WebKit Nightly Build Unspecified Unspecified RESOLVED FIXED InRadar P2 Normal --- 1 msaboff msaboff ews-watchlist keith_miller lokihardt mark.lam saam webkit-bug-importer oldest_to_newest 1537796 0 msaboff 2019-05-20 20:36:50 -0700 In initParenContextFreeList() we use INT16_MAX to determine if we should create a ParenContext free list. We should be using the VM::patternContextBufferSize, as that is the amount of memory we have available when executing the JIT'ed code. We should also fail the compile instead of bailing out with a jump to the JIT code failure return as this could potentially save JIT memory that could be consumed by large RegExp functions that won't execute to completion due to their ParenContext size exceeding VM::patternContextBufferSize. 1537797 1 msaboff 2019-05-20 20:37:00 -0700 <rdar://problem/50427019> 1537803 2 370296 msaboff 2019-05-20 20:48:56 -0700 Created attachment 370296 Patch 1537927 3 keith_miller 2019-05-21 11:03:58 -0700 I already fixed this in https://trac.webkit.org/changeset/245586.
