* Create pylint.yml
* improve file matching
* fix some pylint issues
* run on PR and push (force on master only)
* more pylint fixes
* suppress noisy exit code and filter to fatals
* add conan as a dep so the module is importable
* fix lint error on unreachable branch
* Adds -lm linker flag for (Free|Open)BSD and uses github.com/bazelbuild/platforms for platform detection.
* Prefer selects.with_or to select the linkopts.
* @platforms appears to be implicitly available. @bazel_skylib would require updating every dependent repository.
* Re-enable platforms package.
Fixes#974. The `cxx_feature_check` now has an additional
optional argument which can be used to supply extra cmake flags
to pass to the `try_compile` command. The `CMAKE_CXX_STANDARD=14`
flag was determined to be the minimum flag necessary to correctly
compile and run the regex feature checks when compiling with Clang
under Windows (n.b. this does *not* refer to clang-cl, the frontend
to the MSVC compiler). The additional flag is not enabled for any
other compiler/platform tuple.
* Add CartesianProduct with associated test
* Use CartesianProduct in Ranges to avoid code duplication
* Add new cartesian_product_test to CMakeLists.txt
* Update AUTHORS & CONTRIBUTORS
* Rename CartesianProduct to ArgsProduct
* Rename test & fixture accordingly
* Add example for ArgsProduct to README
* ctest is now working
* Update README
* remove commented out lines
* Tweaked docs
Added note to use parallel and cleaned build config notes
* Response to comments
* revert all but the readme
* make error message clearer
* drop --parallel
Build instructions needlessly referred to make when CMake offers
a command-line interface to abstract away from the specific build
system.
Furthermore, CMake offers command-line "tool mode" which performs basic
filesystem operations. While the syntax is a bit more verbose than
Linux commands it is platform-independent. Now the commands can be
copy-pasted on both Linux and Windows and will just work.
Finally, the Release build type is included in initial commands. A natural flow
for a new-comer is to read and execute the commands and only then learn
that one has to go back and redo them again this time with proper parameters.
Now instead the parameters are only explained later but present already in the
initial commands.
As noted in #995, this causes issues when the command line flag already
starts with "benchmark_", which they all do.
Not caught by tests as the test flags didn't start with "benchmark".
Fixes#995
* JSONReporter: don't report on scaling if we didn't get it (#1005)
* JSONReporter: fix due to review (std::pair<bool, bool> -> enum)
* JSONReporter: scaling: fix the algo (due to review discussion)
* benchmark.h: revert to old-fashioned enum's (C++03 compatibility); rreporter_output_test: let's skip scaling
* add requirements.txt for python tools
* adds documentation for requirements.txt
Adds installation instructions for python dependencies using pip and requirements.txt
* timestamp: use rfc3339-formatted timestamps in output
Replace localized timestamps with machine-readable IETF RFC 3339 format
timestamps. This is an attempt to make the output timestamps easily
machine-readable. ISO8601 specifies standards for time interchange
formats. IETF RFC 3339: https://tools.ietf.org/html/rfc3339 defines a
subset of these for use in the internet. The general form for these
timestamps is:
YYYY-MM-DDTHH:mm:SS[+-]hhmm
This replaces the localized time formats that are currently being used
in the benchmark output to prioritize interchangeability and
machine-readability.
This might break existing programs that rely on the particular date-time
format. This might also may make times less human readable. RFC3339 was
intended to balance human readability and simplicity for machine
readability, but it is primarily intended as an internal representation.
* timers: remove utc string formatting
We only ever need local time printing. Remove the UTC printing
and cosnolidate the logic slightly.
* timers: manually create rfc3339 string
The C++ standard library does not output the time offset in RFC3339
format, it is missing the : between hours and minutes. VS does not
appear to support timezone information by default. To avoid adding too
much complexity to benchmark around timezone handling e.g. a full
date library like https://github.com/HowardHinnant/date, we fall back
to outputting GMT time with a -00:00 offset for those cases.
* timers: use reentrant form for localtime_r & tmtime_r
For non-windows, use the reentrant form for the time conversion
functions.
* timers: cleanup
Use strtol instead of brittle moving characters around.
* timers: only call strftime twice.
Also size buffers to known maximum necessary size and name constants
more appropriately.
* timers: fix unused variable warning
* Add missing <cerrno> header
This commit fixes a current build error on Android where 'errno' is an unidentified
symbol due to a missing header
* Update string_util.cc
Conditionally adds <cerrno> if BENCHMARK_STL_ANDROID_GNUSTL is defined
In a previous commit[1], diagnostic pragmas were used to avoid this
warning. However, the incorrect warning flag was indicated, leaving the
warning in place. -Wdeprecated is for deprecated features while
-Wdeprecated-declarations for deprecated functions, variables, and
types[2].

Fixes the following issues with the implementation of `cycleclock::Now`:
- The RISC-V implementation wouldn't compile due to a typo;
- Both the PPC and RISC-V implementation's asm statements lacked the
volatile keyword. This resulted in the repeated read of the counter's
high part being optimized away, so overflow wasn't handled at all.
Multiple counter reads could also be misoptimized, especially in LTO
scenarios.
- Relied on the zero/sign-extension of inline asm operands, which isn't
guaranteed to occur and differs between compilers, namely GCC and Clang.
The PowerPC64 implementation was improved to do a single 64-bit read of
the time-base counter.
The RISC-V implementation was improved to do the overflow handing in
assembly, since Clang would generate a branch, defeating the purpose
of the non-branching counter reading approach.
* Fix type conversion warnings.
Fixes#949
Tested locally (Linux/clang), but warnings are on MSVC so may differ.
* Drop the ULP so the double test passes
Line "- /usr/local/bin:$PATH" is misformatted.
It must be something like "- PATH=/usr/local/bin:$PATH".
It seems something changed in tarvis-ci month ago and now this leads to:
Setting environment variables from .travis.yml
$ export PATH=
Defailt PATH is /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin
so already containts /usr/local/bin.
Image "xcode8.3" contains macOS 10.12 (sierra) which has no bottles
with precompiled gcc-7 in homebrew storage.
Image "xcode9.4" is a current default with macOS 10.13 (high_sierra).
