By doing so, we spare readers from seeing partially-updated\nproperty values if they race with the property service\u0027s non-atomic\nmemcpy to the property value slot. (The futex-wait here isn\u0027t\nessential to the algorithm: spinning while dirty would suffice,\nalthough it\u0027d be somewhat less efficient.)\n\nThe problem with this approach is that readers can wait on the\nproperty service process, potentially causing delays due to scheduling\nvariance. Property reads are not guaranteed to complete in finite time\nright now.\n\nThis change makes property reads wait-free and ensures that they\ncomplete in finite time in all cases. In the new approach, we prevent\nvalue tearing by backing up each property we\u0027re about to modify and\ndirecting readers to the backup copy if they try to read a property\nwith the dirty bit set.\n\n(The wait freedom is limited to the case of readers racing against\n*one* property update. A writer can still delay readers by rapidly\nupdating a property --- but after this change, readers can\u0027t hang due\nto PID 1 scheduling delays.)\n\nI considered adding explicit atomic access to short property values,\nbut between binary compatibility with the existing property database\nand the need to carefully handle transitions of property values\nbetween \"short\" (compatible with atomics) and \"long\" (incompatible\nwith atomics) length domains, I figured the complexity wasn\u0027t worth it\nand that making property reads wait-free would be adequate.\n\nTest: boots\nBug: 143561649\nChange-Id: Ifd3108aedba5a4b157b66af6ca0a4ed084bd5982\n" }, { "commit": "c4e727bff3eddbb624d7038fac88637d8afebd2b", "tree": "2cf8989bb8f37fef1e0e7a9f49e98d1fea35c9f8", "parents": [ "64b6a0b87e402e02138bce95bfa90dbe89647c3b" ], "author": { "name": "Steven Moreland", "email": "smoreland@google.com", "time": "Tue Oct 15 10:26:44 2019 -0700" }, "committer": { "name": "Steven Moreland", "email": "smoreland@google.com", "time": "Wed Oct 16 08:59:06 2019 -0700" }, "message": "Add dladdr benchmark.\n\nBug: 142684469\nTest: adb shell /data/benchmarktest64/bionic-benchmarks/bionic-benchmarks --benchmark_filter\u003d\"BM_dladdr.*\"\n-------------------------------------------------------------------\nBenchmark Time CPU Iterations\n-------------------------------------------------------------------\nBM_dladdr_libbase_split 92.6 ns 92.4 ns 6673841\nBM_dladdr_libc_printf 8690 ns 8667 ns 80916\nBM_dladdr_libdl_dladdr 133 ns 132 ns 5342791\nBM_dladdr_local_function 93.0 ns 92.7 ns 7625562\n\nChange-Id: I259dd8f64ccc288835576a2eb08b8b8132777a4b\n" }, { "commit": "a4959aa6f819df0efdab6995e5de530655734389", "tree": "7f2ceae2b6c167bbfd20d1e9bbc9c1d52ff6fa7e", "parents": [ "29ec2881a0a87ccda75c77fd967934d863d53cc1" ], "author": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Tue Oct 08 12:04:09 2019 -0700" }, "committer": { "name": "Elliott Hughes", "email": "enh@google.com", "time": "Tue Oct 08 12:04:09 2019 -0700" }, "message": "Reimplement the \u003cctype.h\u003e is* functions.\n\nFollowing on from the towlower()/towupper() changes, add benchmarks for\nmost of \u003cctype.h\u003e, rewrite the tests to cover the entire defined range\nfor all of these functions, and then reimplement most of the functions.\n\nThe old table-based implementation is mostly a bad idea on modern\nhardware, with only ispunct() showing a significant benefit compared to\nany other way I could think of writing it, and isalnum() a marginal but\nstill convincingly genuine benefit.\n\nMy new benchmarks make an effort to test an example from each relevant\nrange of characters to avoid, say, accidentally optimizing the behavior\nof `isalnum(\u00270\u0027)` at the expense of `isalnum(\u0027z\u0027)`.\n\nInterestingly, clang is able to generate what I believe to be the\noptimal implementations from the most readable code, which is\nimpressive.
