#
|
|
# 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.
