The whitespace sensitivity of field args was starting to be a problem,
mostly for advanced plotmpl.py usage (which tbf might be appropriately
described as "super hacky" in how it uses CLI parameters):
./scripts/plotmpl.py \
-Dcase=" \
bench_rbyd_attr_append, \
bench_rbyd_attr_remove, \
bench_rbyd_attr_fetch, \
..."
This may present problems when parsing CSV files with whitespace, in
theory, maybe. But given the scope of these scripts for littlefs...
just don't do that. Thanks.
With the quantity of data being output by bench.py now, filtering ASAP
while parsing CSV files is a valuable optimization. And thanks to how
CSV files are structured, we can even avoid ever loading the full
contents into RAM.
This does end up with use filtering for defines redundantly in a few
places, but this is well worth the saved overhead from early filtering.
Also tried to clean up the plot.py/plotmpl.py's data folding path,
though that may have been wasted effort.
These benchmarks are now more useful for seeing how these B-trees perform.
In plot.py/plotmpl.py:
- Added --legend as another alias for -l, --legend-right.
- Allowed omitting of datasets from the legend by using empty strings
in --labels.
- Do not sum multiple data points on the same x coordinate. This was a
bad idea that risks invalid results going unnoticed.
As a plus multiple data points on the same x coordinate can be abused for
a cheap representation of measurement error.
- Added both uattr (limited to 256) and id (limited to 65535) benchmarks
covering the main rbyd operations
- Fixed issue where --defines gets passed to the test/bench runners when
querying id-specific information. After changing the test/bench
runners to prioritize explicit defines, this causes problems for
recorded benchmark results and debug related things.
- In plot.py/plotmpl.py, made --by/-x/-y in subplots behave somewhat
reasonably, contributing to a global dataset and the figure's legend,
colors, etc, but only shown in the specified subplot. This is useful
mainly for showing different -y values on different subplots.
- In plot.py/plotmpl.py, added --labels to allow explicit configuration
of legend labels, much like --colors/--formats/--chars/etc. This
removes one of the main annoying needs for modifying benchmark results.
Driven primarily by a want to compare measurements of different runtime
complexities (it's difficult to fit O(n) and O(log n) on the same plot),
this adds the ability to nest subplots in the same .svg which try to align
as much as possible. This turned out to be surprisingly complicated.
As a part of this, adopted matplotlib's relatively recent
constrained_layout, which behaves much more consistently.
Also dropped --legend-left, no one should really be using that.
The difference between ggplot's gray and GitHub's gray was a bit jarring.
This also adds --foreground and --font-color for this sort of additional
color control without needing to add a new flag for every color scheme
out there.
- Fixed prettyasserts.py parsing when '->' is in expr
- Made prettyasserts.py failures not crash (yay dynamic typing)
- Fixed the initial state of the emubd disk file to match the internal
state in RAM
- Fixed true/false getting changed to True/False in test.py/bench.py
defines
- Fixed accidental substring matching in plot.py's --by comparison
- Fixed a missed LFS_BLOCk_CYCLES in test_superblocks.toml that was
missed
- Changed test.py/bench.py -v to only show commands being run
Including the test output is still possible with test.py -v -O-, making
the implicit inclusion redundant and noisy.
- Added license comments to bench_runner/test_runner
Note that plotmpl.py tries to share many arguments with plot.py,
allowing plot.py to act as a sort of draft mode for previewing plots
before creating an svg.
