1 HEAP PROFILER 2 3 1) Fix heap profiling under all STLs 4 * Find out how to force non-glibc STL libraries to call new() and 5 delete() for every allocation / deallocation. 6 * Make heap profiler ignore STL-internal allocations for those 7 libraries under which we cannot profile accurately, so we only 8 see object-level leaks. 9 2) Remove dependency on tcmalloc? 10 3) Port to non-linux O/Ses (right now code uses /proc for library info) 11 4) Port to non-x86 architectures (locking code in spinlock is x86-specific) 12 5) Port to C? 13 6) Figure out how to get setenv() to work properly before main() in 14 shared libaries, and get rid of the profile-naming hack once we 15 do. (See HeapProfiler::Init().) 16 17 18 HEAP CHECKER 19 20 1) Remove requirement that the heap-checker must be linked last into 21 an application (hard! -- it needs its global constructor to run 22 first) 23 24 TCMALLOC 25 26 1) Implement mallinfo/mallopt 27 2) Have tcmalloc work correctly when libpthread is not linked in 28 (currently working for glibc, could use other libc's too) 29 3) Return memory to the system when requirements drop 30 4) Explore coloring allocated objects to avoid cache conflicts 31 5) Explore biasing reclamation to larger addresses 32 6) Add contention stats to a synchronization.cc (can do spinlocks, 33 but threads? -- may have to provide our own thread implementation) 34 35 CPU PROFILER 36 37 1) Figure out how to get setenv() to work properly before main() in 38 shared libaries(), and get rid of the profile-naming hack once we 39 do. (See Profiler::GetUniquePathFromEnv().) 40 2) Resolve crashing problems on x86_64 (see README) 41 42 STACKTRACE 43 44 1) Remove dependency on linux/x86 45 46 --- 47 11 March 2008 48
