Fix broken format in error for bad input in summarize_stats.py (#117375)
When you pass the script a non-existent input file, you get a TypeError instead of the intended ValueError.

gh-115168: Add pystats counter for invalidated executors (GH-115169) 2024-02-26 17:51:47 +00:00
Guido van Rossum 142502ea8d
Tier 2 cleanups and tweaks (#115534)
* Rename `_testinternalcapi.get_{uop,counter}_optimizer` to `new_*_optimizer`
* Use `_PyUOpName()` instead of` _PyOpcode_uop_name[]`
* Add `target` to executor iterator items -- `list(ex)` now returns `(opcode, oparg, target, operand)` quadruples
* Add executor methods `get_opcode()` and `get_oparg()` to get `vmdata.opcode`, `vmdata.oparg`
* Define a helper for printing uops, and unify various places where they are printed
* Add a hack to summarize_stats.py to fix legacy uop names (e.g. `POP_TOP` -> `_POP_TOP`)
* Define helpers in `test_opt.py` for accessing the set or list of opnames of an executor

gh-110152: regrtest handles cross compilation and HOSTRUNNER (#110156)
* _add_python_opts() now handles cross compilation and HOSTRUNNER.
* display_header() now tells if Python is cross-compiled, display
  HOSTRUNNER, and get the host platform.
* Remove Tools/scripts/run_tests.py script.
* Remove "make hostrunnertest": use "make buildbottest"
  or "make test" instead.

gh-109566: regrtest reexecutes the process (#109909)
When --fast-ci or --slow-ci option is used, regrtest now replaces the
current process with a new process to add "-u -W default -bb -E"
options to Python.

Changes:

* PCbuild/rt.bat and Tools/scripts/run_tests.py no longer need to add
  "-u -W default -bb -E" options to Python: it's now done by
  regrtest.
* Fix Tools/scripts/run_tests.py: flush stdout before replacing the
  process. Previously, buffered messages were lost.

gh-109566, regrtest: Add --fast-ci and --slow-ci options (#109570)
* Add --fast-ci and --slow-ci options to libregrtest:

  * --fast-ci uses a default timeout of 10 minutes and "-u all,-cpu"
    (skip slowest tests).
  * --slow-ci uses a default timeout of 20 minues and "-u all" (run
    all tests).

* regrtest header now lists test resources.
* Makefile changes:

  * "make test", "make hostrunnertest" and "make coverage-report" now
    use --fast-ci option and TESTTIMEOUT variable.
  * "make buildbottest" now uses "--slow-ci". Remove options which
    became redundant with "--slow-ci".
  * "make testall" and "make testuniversal" now use --slow-ci option
    and TESTTIMEOUT variable.
  * "make testall" now uses "find -exec rm ..." instead of
    "find ... -print|xargs rm ...", same as "make clean".

* GitHub Actions workflow:

  * Ubuntu and Address Sanitizer jobs now use "make test". Remove
    options which became redundant with "--fast-ci".
  * Windows jobs now use --fast-ci option.
  * Use -j0 to detect the number of CPUs.

* Set Makefile TESTTIMEOUT default to an empty string, since
  --slow-ci and --fast-ci use different default timeout. It's now
  accepted to pass "--timeout=" to regrtest: treated as not timeout.
* Tools/scripts/run_tests.py now uses --fast-ci option.
* Tools/buildbot/test.bat now uses --slow-ci option. Remove
  --timeout=1200 option, redundant with --slow-ci.

Support comparing two sets of pystats (GH-98816)
This adds support for comparing pystats collected from two different builds.

- The `--json-output` can be used to load in a set of raw stats and output a
  JSON file.
- Two of these JSON files can be provided on the next run, and then comparative
  results between the two are output.

gh-90716: add _pylong.py module (#96673)
Add Python implementations of certain longobject.c functions. These use
asymptotically faster algorithms that can be used for operations on
integers with many digits. In those cases, the performance overhead of
the Python implementation is not significant since the asymptotic
behavior is what dominates runtime. Functions provided by this module
should be considered private and not part of any public API.

The "pyperf command" tool be used instead. Example:

    $ python3 -m pyperf command -- python3 -c pass

    command: Mean +- std dev: 17.8 ms +- 0.4 ms

pyperf also computes the standard deviation which gives an idea of
the benchmark looks reliable or not.
