RESOLVED DUPLICATE of bug 21272 21273
Switching between custom allocators (TCmalloc, JEmalloc) in linux-qt

Summary Switching between custom allocators (TCmalloc, JEmalloc) in linux-qt
Zoltan Horvath
Reported 2008-10-01 03:24:00 PDT
We modified build system of WebKit under linux-qt to use TCmalloc if “--tcmalloc” parameter is given to build-webkit script. Even more, we integrated JEmalloc into WebKit as well which is used if "--jemalloc" parameter is given to build-webkit script. (In Mozilla the default allocator is JEmalloc.) If we do not give any of these parameters to the build these libraries are not used. There are three patches: (enable_tcmalloc.patch) enables TCmalloc in WebKit (without JEmalloc) (enable_jemalloc.patch JEmalloc.h.patch JEmalloc.c.patch rb.h.patch) adds JEmalloc to WebKit (without enabling TCmalloc) (enable_jetcmalloc.patch JEmalloc.h.patch JEmalloc.c.patch rb.h.patch) enables TCmalloc and adds JEmalloc at the same time (in this case the user can switch between the allocators in compile time) Since under linux-qt global operator new and delete do not invoke allocators of TC/JEmalloc, therefore only fastMalloc invokes them. On the other hand, the experimental patches of bug #20422 (https://bugs.webkit.org/show_bug.cgi?id=20422) gives a solution where new and delete also invoke custom allocators (TC/JEmalloc).
