Add user-defined counters. (#262)
* Added user counters, and move use of bytes_processed and items_processed to user counter logic. Each counter is a string-value pair. The counters were made available through the State class. Two helper virtual methods were added to the Fixture class to allow convenient initialization and termination of the counters: InitState() and TerminateState(). The reporting of the counters is buggy and is still a work in progress, to be completed in the next commits. * fix bad removal of BenchmarkCounters code during the merge * add myself to AUTHORS/CONTRIBUTORS * fix printing to std::cout in csv_reporter * bytes_per_second and items_per_second are now in the UserCounters class * add user counters to json reporter * moving bytes_per_second and items_per_second to their old state * console reporter dealing ok with user counters. * update unit tests for user counters * CSVReporter now prints user counters too. * cleanup user counters * reverted changes to cmake files which should have gone into later commits * fixture_test: fix gcc 4.6 compilation * remove ctor with default argument see https://github.com/google/benchmark/pull/262#discussion_r72298055 * use (auto-defined) BENCHMARK_HAS_CXX11 instead of BENCHMARK_INITLIST. https://github.com/google/benchmark/pull/262#discussion_r72298310 * leanify counters API Discussions: API complexity: https://github.com/google/benchmark/pull/262#discussion_r72298731 remove std::string dependency (WIP): https://github.com/google/benchmark/pull/262#discussion_r72298142 spacing & alignment: https://github.com/google/benchmark/pull/262#discussion_r72298422 * remove std::string dependency on public API - changed counter name storage to char* * Counter ctor: use overloads instead of default arguments discussion: https://github.com/google/benchmark/pull/262#discussion_r72298055 * Use raw pointers to remove dependency on std::vector from public API . For more info, see discussion at https://github.com/google/benchmark/pull/262#discussion_r72319678 . * Move counter implementation from benchmark.cc to counter.cc. See discussion: https://github.com/google/benchmark/pull/262#discussion_r72298980 . * Remove unused (commented-out) code. * Moved thread counters to ThreadStats. * Counters: fixed copy and move constructors. * Counter: use an inplace buffer for small names. * benchmark_test: move counters test out of CXX11 preprocessor conditional. * Counter: fix VS2013 compilation error in char[] initialization. * Fix typo. * Expose counters from State. See discussion: https://github.com/google/benchmark/pull/262#issuecomment-237156951 * Changed counters interface to map-like. * Fix printing of user counters in ConsoleReporter. * Applied clang-format to counter.cc and console_reporter.cc. Command was `clang-format -style=Google -i counter.cc console_reporter.cc` I also applied to all other files, but the changes were very far-reaching so I rolled those back. * Rename Counter::Flags_e to Counter::Flags * Fix use of reserved names in Counter and BenchmarkCounters. * Counter: Fix move ctor bug + change order of members. * Fixture: remove tentative methods InitState() and TerminateState(). * Update fixture_test to the new Fixture interface. * BenchmarkCounters: fixed a bug in the move ctor. Remove call to CHECK_LT(). CHECK_LT() was making the size_t lookup take ~double the time of a string lookup! * BenchmarkCounters: add option to not print zero counters (defaults to false). * Add test to compare counter storage and access with std::map. * README: clarify cost of counter access modes. * move counter access test to an own test. * BenchmarkCounters: add move Insert() * Counters access test: add accelerated lookup by name. * Fix old range syntax. * Fix missing include of cstdio * Fix Visual Studio warning * VS2013 and lower: fix use of snprintf() * VS2013: fix use of char[] as a member of std::pair<>. * change counter storage to std::map * Remove skipZeroCounters logic * Fix VS compilation error. * Implemented request changes to PR #262. * PR #262: More requested changes. * README: cleanup counter text. * PR #262: remove clang-format changes for preexisting code * Complexity+Counters: fix counter flags which were being ignored. * Document all Counter::Flag members * fixed loss of counter values * ConsoleReporter: remove tabular printing of user counters. * ConsoleReporter: header printing should not be contingent on user counter names. * Minor white space and alignment fixes. * cxx03_test + counters: reuse the BM_empty() function. * user counters: add note to README on how counters are gathered across threads

## User-defined counters
|
||||
|
||||
You can add your own counters with user-defined names. The example below
|
||||
will add columns "Foo", "Bar" and "Baz" in its output:
|
||||
|
||||
```c++
|
||||
static void UserCountersExample1(benchmark::State& state) {
|
||||
double numFoos = 0, numBars = 0, numBazs = 0;
|
||||
while (state.KeepRunning()) {
|
||||
// ... count Foo,Bar,Baz events
|
||||
}
|
||||
state.counters["Foo"] = numFoos;
|
||||
state.counters["Bar"] = numBars;
|
||||
state.counters["Baz"] = numBazs;
|
||||
}
|
||||
```
|
||||
|
||||
The `state.counters` object is a `std::map` with `std::string` keys
|
||||
and `Counter` values. The latter is a `double`-like class, via an implicit
|
||||
conversion to `double&`. Thus you can use all of the standard arithmetic
|
||||
assignment operators (`=,+=,-=,*=,/=`) to change the value of each counter.
|
||||
|
||||
In multithreaded benchmarks, each counter is set on the calling thread only.
|
||||
When the benchmark finishes, the counters from each thread will be summed;
|
||||
the resulting sum is the value which will be shown for the benchmark.
|
||||
|
||||
The `Counter` constructor accepts two parameters: the value as a `double`
|
||||
and a bit flag which allows you to show counters as rates and/or as
|
||||
per-thread averages:
|
||||
|
||||
```c++
|
||||
// sets a simple counter
|
||||
state.counters["Foo"] = numFoos;
|
||||
|
||||
// Set the counter as a rate. It will be presented divided
|
||||
// by the duration of the benchmark.
|
||||
state.counters["FooRate"] = Counter(numFoos, benchmark::Counter::kIsRate);
|
||||
|
||||
// Set the counter as a thread-average quantity. It will
|
||||
// be presented divided by the number of threads.
|
||||
state.counters["FooAvg"] = Counter(numFoos, benchmark::Counter::kAvgThreads);
|
||||
|
||||
// There's also a combined flag:
|
||||
state.counters["FooAvgRate"] = Counter(numFoos,benchmark::Counter::kAvgThreadsRate);
|
||||
```
|
||||
|
||||
When you're compiling in C++11 mode or later you can use `insert()` with
|
||||
`std::initializer_list`:
|
||||
|
||||
```c++
|
||||
// With C++11, this can be done:
|
||||
state.counters.insert({{"Foo", numFoos}, {"Bar", numBars}, {"Baz", numBazs}});
|
||||
// ... instead of:
|
||||
state.counters["Foo"] = numFoos;
|
||||
state.counters["Bar"] = numBars;
|
||||
state.counters["Baz"] = numBazs;
|
||||
```

||||
