- # Roll our own custom logic here for the import library
- ###############################################################################
- #
- # Linking Mozilla itself to jemalloc is not particularly difficult. To do this
- # we avoid linking directly to the Microsoft-provided CRT import libraries.
- # Instead, we link to our own import library which we generate here. To
- # replace the CRT's malloc/free/other memory management symbols we export
- # our own versions out of jemalloc.dll. We then take the import library that
- # the compiler generates for jemalloc.dll and combine it with the MS CRT import
- # libraries. We put our library on the command line first, and the CRT symbols
- # are discarded in favor of our versions!
- #
- # Unfortunately that was too easy. The CRT import library is not a standard
- # import library that contains a list of symbols and whatnot. It also includes
- # object files that are linked into generated programs. One of these,
- # crtdll.obj is (as one might expect) linked into all DLLs that link against
- # the CRT. This file does things like run static C++ constructors when the
- # DLL is attached, call DllMain, etc.
- #
- # In the CRT source all malloc/free calls are made to malloc_crt and free_crt.
- # In debug builds these are both defined to malloc_dbg and free_dbg. In opt
- # builds malloc_crt is an actual function, implemented and exposed from the
- # CRT. free_crt is, however, defined to be just plain old free. This works
- # fine inside the CRT where malloc_crt and free operate on the same heap.
- # Outside the CRT malloc_crt is in the CRT's heap, but free is in jemalloc's
- # heap. This causes much pain at shutdown :-(
- #
- # The obvious solution here is to override malloc_crt too. Unfortunately,
- # that doesn't work because the CRT expects to be able to call msize on this
- # piece of memory deep inside the CRT, which will fail because it'll call the
- # CRT's msize on a pointer in jemalloc's heap.
- #
- # Our solution to this is quite devious. We take apart the CRT's import lib
- # and remove the problematic object file. We then poke at the object file's
- # symbol table and replace '__imp__free' (which means grab free from some
- # other DLL) with '__imp__frex'. Then we define our own dummy no-op function
- # in jemalloc.dll and export it as frex. Then we put the CRT import lib
- # back together with the patched crtdll.obj, glue it to the end of jemalloc's
- # import library and link the rest of Mozilla to that.
- #
- # The result? A binary that uses jemalloc, doesn't crash, and leaks a tiny
- # amount of memory (32 words per DLL in the 2010 CRT) at shutdown.
