* gh-130599: use static constants str-to-int conversion (gh-130714)Neil Schemenauer2025-03-041-0/+75
| | | | | | Avoid a data race in free-threaded builds due to mutating global arrays at runtime. Instead, compute the constants with an external Python script and then define them as static global constant arrays. These constants are used by `long_from_non_binary_base()`.

| | | | | | | the code generators (GH-128918)" (GH-129202) The commit introduced a ~2.5-3% regression in the free threading build. This reverts commit ab61d3f4303d14a413bc9ae6557c730ffdf7579e.

* Fix broken format in error for bad input in summarize_stats.py (#117375)Guido van Rossum2024-03-291-1/+1
| | | When you pass the script a non-existent input file, you get a TypeError instead of the intended ValueError.

|
* Tier 2 cleanups and tweaks (#115534)Guido van Rossum2024-02-201-0/+4
| | | | | | | | | * 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-58032: Do not use argparse.FileType in module CLIs and scripts (GH-113649)Serhiy Storchaka2024-01-101-3/+3
| | | | | Open and close files manually. It prevents from leaking files, preliminary creation of output files, and accidental closing of stdin and stdout.
* gh-112320: Implement on-trace confidence tracking for branches (#112321)Guido van Rossum2023-12-121-0/+2
| | | We track the confidence as a scaled int.
* gh-111277: In summarize_stats.py, don't fail fast on invalid ratios (#111278)Michael Droettboom2023-10-311-3/+5
|
* gh-109329: Count tier2 opcode misses (#110561)Michael Droettboom2023-10-311-1/+1
| | | This keeps a separate 'miss' counter for each micro-opcode, incremented whenever a guard uop takes a deoptimization side exit.

* gh-110152: regrtest handles cross compilation and HOSTRUNNER (#110156)Victor Stinner2023-09-301-78/+0
| | | | | | | | * _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)Victor Stinner2023-09-261-7/+3
| | | | | | | | | | | | | 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)Victor Stinner2023-09-261-11/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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.
