Colin Cross	cecd64012d	Silently ignore duplicate heap entries ... Vendor blobs on ryu mprotect heap pages, causing a single chunk mapping to appear as multiple mappings. The heap iterator has to expand the requested range to cover the beginning of the chunk to find the chunk metadata, which will lead to duplicate identical allocations being reported from iterating over each of the split mappings. Silently ignore identical allocations, and only warn on non-identical allocations that overlap. Bug: 28269332 Change-Id: Ied2ab9270f65d00a887c7ce1a93fbf0617d69be0	2016-04-28 16:20:40 -07:00
Colin Cross	ba5d9ff6d9	Handle segfaults while walking native heap ... Vendor blobs on ryu mprotect heap pages, causing segfaults when dumping unreachable memory. Handle segfaults within HeapWalker by mapping a zero page over any unreadable pages. HeapWalker runs in the forked process, so the mapping will not affect the original process.

Colin Cross	4c5bccdd86	Fix allocator::map template argument ordering ... allocator::map reversed Key and T from std::map Bug: 27208635 Change-Id: I4e4db704539d01b060cb948aa573cb674da48c7d	2016-03-04 16:40:02 -08:00
Colin Cross	8e8f34c558	Fold leaks that are referenced by other leaks ... Find leaks that have no references at all, or are only referenced by other leaks in the same strongly connected component, and hide all referenced leaks. Bug: 27208635 Change-Id: Ifbfd14e24e2ba0f8af7c1b887e57f34362720f2d	2016-03-04 16:39:59 -08:00
Colin Cross	7add50d820	imprecise mark and sweep native memory leak detector ... libmemunreachable uses an imprecise mark and sweep pass over all memory allocated by jemalloc in order to find unreachable allocations. Bug: 27208635 Change-Id: Ia70bbf31f5b40ff71dab28cfd6cd06c5ef01a2d4 (cherry picked from commit bcb4ed3eaa)	2016-02-19 00:49:36 -08:00
