PHPBench 1.2.0Last modified 2022/09/14 11:14
PHPBench 1.2.0 has been released, the highlights are:
- In reports you can now dynamically create and group columns in tables
- Memory can be displayed in binary memory units
- Support for filtering by variant name
- Support for filtering reports
Report Improvements ¶
This release improves table generation, adding support for grouping and expanding columns dynamically:
The example above is using the new
phpbench run --report=benchmark_compare --output=html
Memory as Binary Units ¶
Support has been added for binary memory
units - i.e.
You are able to specify these units in the expression language or use them by
default by setting the
expression.memory_unit_prefix setting to
Filter by Variant ¶
Previous to 1.2.0 you could filter benchmarks/subjects using the
This worked fine until you wanted to isolate one or more variants (i.e. parameterised subjects).
Filtering by variant isn’t that easy though, as it requires loading all the parameters for each subject before we able to know if we can filter them or not. The existing behavior where we filtering by benchmark class and subject is more efficient.
For this reason an additional
option has been added
--variant="this is my parameter set".
Filter Reports ¶
It is possible to both run a benchmark and compare the results against a previous run:
phpbench run --ref=previous --report=benchmark_compare --filter=myThing
If you were to apply a filter however, the filter would only apply to the current run, and would not be applied to the referenced benchmark, which meant that the report generated report would contain much more than you may have anticipated.
As of 1.2.0 the filtering works as expected, and additionally it also works on previously generated reports:
phpbench report --ref=new --ref=previous --report=benchmark_compare --filter=myThing --variant="my variant"
PHPBench 1.2.0 brings some nice improvements… and there was much rejoicing.
