While I\u0027m here, I\u0027ve tried to clean up some of the mess\nthat led to this situation too. In particular, this removes libc/private/ from\nthe default include path (except for the DNS code), and splits out the DNS\ncode into its own library (since it\u0027s a weird special case of upstream NetBSD\ncode that\u0027s diverged so heavily it\u0027s unlikely ever to get back in sync).\n\nThere\u0027s more cleanup of the DNS situation possible, but this is definitely a\nstep in the right direction, and it\u0027s more than enough to get x86_64 building\ncleanly.\n\nChange-Id: I00425a7245b7a2573df16cc38798187d0729e7c4\n" }, { "commit": "35c1862cdfcd87b5ef6c59128b9993efffafe88b", "tree": "8af488889834eb365ed3f99c995e9843e4de1b7b", "parents": [ "6088047a64abb1e8a27fcb9868b00a630fbdfed4" ], "author": { "name": "Nick Kralevich", "email": "nnk@google.com", "time": "Thu Oct 03 14:59:05 2013 -0700" }, "committer": { "name": "Nick Kralevich", "email": "nnk@google.com", "time": "Thu Oct 03 14:59:05 2013 -0700" }, "message": "Don\u0027t export unnecessary symbol.\n\nChange-Id: I8b1d75a08476c41dd8e3f09fc93a3df617928f88\n" }, { "commit": "885f3b9cad01b8158aadc55c159c17dbf34f622c", "tree": "55991f909d2a12f185c0773de57cdf01b7074ecd", "parents": [ "b7b4f5b838cd41407c734af74e8211f5c7da0036" ], "author": { "name": "Christopher Ferris", "email": "cferris@google.com", "time": "Tue May 21 17:48:01 2013 -0700" }, "committer": { "name": "Christopher Ferris", "email": "cferris@google.com", "time": "Fri Jun 07 14:55:32 2013 -0700" }, "message": "Implement malloc_usable_size for debug impls.\n\n- Implemented chk_memalign.\n- Fixed a few bugs in leak_memalign.\n- Implemented {leak,fill,check,qemu}_malloc_usable_size.\n- Make malloc_usable_size update at run time.\n- Add malloc_test.cpp as a small set of tests for the\n malloc debug routines.\n- Fix the qemu routines since it\u0027s been broken since it moved to C++.\n- Add support for the %u format to the out_vformat in libc_logging.cpp.\n This is used by the emulator code.\n\nTested using the bionic-unit-tests with setprop libc.debug.malloc\nset to 1, 5, and 10.\n\nI tested as much as possible on the emulator, but tracing doesn\u0027t appear\nto be working properly.\n\nBug: 6143477\n\nMerge change from internal master.\n\n(cherry-picked from commit 3d594c258045783fc9e1956ce7a4d91e302f011e)\n\nChange-Id: I4ae00fffba82315a8c283f35893fd554460722fb\n" }, { "commit": "25a87f7641f066437d15c6d3148d08a6ab9be231", "tree": "3262eadfdc8af97fdd9380d12ed4f53c185aefc5", "parents": [ "f5f29de6ae5a0b74234f111b5691a1e5588671cb" ], "author": { "name": "David \u0027Digit\u0027 Turner", "email": "digit@android.com", "time": "Thu May 23 10:02:02 2013 +0200" }, "committer": { "name": "David \u0027Digit\u0027 Turner", "email": "digit@android.com", "time": "Thu May 23 10:02:02 2013 +0200" }, "message": "Fix declaration of malloc_usable_size()\n\nThe function should take a \u0027const void*\u0027 parameter, instead of \u0027void*\u0027.\nNote that the implementation in upstream-dlmalloc/malloc.c already does\nthis.\n\nFor context, see http://b.android.com/55725\n\nChange-Id: Iefd55cdb8996699189e0545f9195972490306227\n" }, { "commit": "ea489745dcc7c116259b63f0353dc482aa4fe2cd", "tree": "802181aa6a3d4fc74cecab4ed2d144fa5e9094b3", "parents": [ "ed36d95fac5881f78a601e2932f51edfd27c6ba6" ], "author": { "name": "Kito Cheng", "email": "kito@0xlab.org", "time": "Fri Apr 12 16:13:34 2013 +0800" }, "committer": { "name": "Kito Cheng", "email": "kito@0xlab.org", "time": "Fri Apr 12 16:34:38 2013 +0800" }, "message": "Use hidden visibility for internal-use-only functions\n\n -
