Measure more of environment during test
In addition to measuring maximum resident set size, also extract number of voluntary and involuntary context switches from the verbose mode.
LogParser doesn’t use `csv.reader` anymore.
Parsing is handled by a Finite State Machine. Each line is matched against a set of (mutually exclusive) regular expressions that represent known states. When a match is found, corresponding parsing action is taken.
Moved result formatting methods from `PerformanceTestResult` and `ResultComparison` to `ReportFormatter`, in order to free PTR to take more computational responsibilities in the future.
Coverage at 99% according to coverage.py
* `compare_perf_tests.py` now always outputs the same format to stdout as is written to `--output` file
* Added integration test for the main() function
* Added tests for console output (and suppressed it leaking during testing)
* Fixed file name in test’s file header
compare_perf_test.py is now covered with unit tests and public methods are documented in the implementation.
Minor refactoring to better conform to Python conventions:
* classes declared in new style
* proper private method prefix of single underscore
* replacing map with list comprehension where it was clearer
Unit test are executed as part of validation-test.
.gitignore was modified to ignore .coverage and htmlcov artifacts generated by the coverage.py package
* Refactor compare_perf_tests.py
* Fix SR-4601 Report Added and Removed Benchmarks in Performance Comparison
Improved HTML styling.
* Added back support for reading concatenated Benchmark_Driver output
PerformanceTestResults can be merged, computing new MIN, MAX, and running MEAN and SD.
* Handle output from Benchmark_O again
Treat MAX_RSS as optional column
Column names must not contain spaces for tools that auto-format the table.
The extra "(%)" was completely redundant since every value in the column
reads as a percentage.
Both regressions and improvements are sorted by the delta, which in case
of improvements produces the reversed order due to negative values of
delta.
This change makes the improvements ordered 'naturally':
most-improved-first.
Make sure all Python code in the repo specifies which exceptions to
catch when using `except:`.
Regressions can be catched using `flake8-blind-except` going forward.
* E101: indentation contains mixed spaces and tabs
* E111: indentation is not a multiple of four
* E128: continuation line under-indented for visual indent
* E302: expected 2 blank lines, found 1
* W191: indentation contains tabs
When comparing scores from either multiple samples, or multiple runs,
print (?) if scores for the configurations being compared have
overlapping ranges.
