| HEAP PROFILER |
| |
| 1) Fix heap profiling under all STLs |
| * Find out how to force non-glibc STL libraries to call new() and |
| delete() for every allocation / deallocation. |
| * Make heap profiler ignore STL-internal allocations for those |
| libraries under which we cannot profile accurately, so we only |
| see object-level leaks. |
| 2) Remove dependency on tcmalloc? |
| 3) Port to non-linux O/Ses (right now code uses /proc for library info) |
| 4) Port to non-x86 architectures (locking code in spinlock is x86-specific) |
| 5) Port to C? |
| 6) Figure out how to get setenv() to work properly before main() in |
| shared libaries, and get rid of the profile-naming hack once we |
| do. (See HeapProfiler::Init().) |
| |
| |
| HEAP CHECKER |
| |
| 1) Remove requirement that the heap-checker must be linked last into |
| an application (hard! -- it needs its global constructor to run |
| first) |
| |
| TCMALLOC |
| |
| 1) Implement mallinfo/mallopt |
| 2) Have tcmalloc work correctly when libpthread is not linked in |
| (currently working for glibc, could use other libc's too) |
| 3) Return memory to the system when requirements drop |
| 4) Explore coloring allocated objects to avoid cache conflicts |
| 5) Explore biasing reclamation to larger addresses |
| 6) Add contention stats to a synchronization.cc (can do spinlocks, |
| but threads? -- may have to provide our own thread implementation) |
| |
| CPU PROFILER |
| |
| 1) Figure out how to get setenv() to work properly before main() in |
| shared libaries(), and get rid of the profile-naming hack once we |
| do. (See Profiler::GetUniquePathFromEnv().) |
| 2) Resolve crashing problems on x86_64 (see README) |
| |
| STACKTRACE |
| |
| 1) Remove dependency on linux/x86 |
