* 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-111213: Fix a few broken stats (GH-111216)Mark Shannon2023-10-261-6/+18
|
* gh-110019: Refactor summarize_stats (GH-110398)Michael Droettboom2023-10-241-791/+1041

* 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.

* Support comparing two sets of pystats (GH-98816)Michael Droettboom2022-11-041-122/+364
| | | | | | | | | | 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)Neil Schemenauer2022-10-261-0/+56
| | | | | | | | | | | | 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.

* gh-97669: Create Tools/build/ directory (#97963)Victor Stinner2022-10-1716-4511/+0

| | | | | | | Remove the sys.getdxp() function and the Tools/scripts/analyze_dxp.py script. DXP stands for "dynamic execution pairs". They were related to DYNAMIC_EXECUTION_PROFILE and DXPAIRS macros which have been removed in Python 3.11. Python can now be built with "./configure --enable-pystats" to gather statistics on Python opcodes.
* gh-97669: Remove outdated example scripts (#97675)Victor Stinner2022-10-0440-6538/+1

| | | | | | | | | | | Fix a shell code injection vulnerability in the get-remote-certificate.py example script. The script no longer uses a shell to run "openssl" commands. Issue reported and initial fix by Caleb Shortt. Remove the Windows code path to send "quit" on stdin to the "openssl s_client" command: use DEVNULL on all platforms instead.
