gh-102737: Un-ignore ceval.c in the CI globals check (gh-102745) 
The tool now allows user-added #LINE preprocessor directives.

gh-102738: remove from cases generator the code related to register instructions (#102739) 2023-03-15 21:25:31 +00:00
Alex Waygood 215007b576
Exclude ceval.c from the C-analyzer tool (#102735) 
The "check if generated files are up to date" CI check appears to be currently failing on all PRs (but not on pushes to main) 

See, for example:
- https://github.com/python/cpython/pull/94468
- https://github.com/python/cpython/pull/94468
- https://github.com/python/cpython/pull/102731

This appears to be because the C-analyzer tool doesn't like the `#line` directives introduced in 70185de1ab. I'm advised by the message printed to the terminal in https://github.com/python/cpython/actions/runs/4428706945/jobs/7768216988#step:14:84 that this is the appropriate short-term fix!

gh-102654: Insert #line directives in generated_cases.c.h (#102669) 
This behavior is optional, because in some extreme cases it
may just make debugging harder. The tool defaults it to off,
but it is on in Makefile.pre.in.

Also note that this makes diffs to generated_cases.c.h noisier,
since whenever you insert or delete a line in bytecodes.c,
all subsequent #line directives will change.

gh-81057: Add a CI Check for New Unsupported C Global Variables (gh-102506) 
This will keep us from adding new unsupported (i.e. non-const) C global variables, which would break interpreter isolation.

FYI, historically it is very uncommon for new global variables to get added. Furthermore, it is rare for new code to break the c-analyzer. So the check should almost always pass unnoticed.

Note that I've removed test_check_c_globals. A test wasn't a great fit conceptually and was super slow on debug builds. A CI check is a better fit.

This also resolves gh-100237.

gh-81057: Vendor a Subset of distutils for the c-analyzer Tool (gh-102505) 
distutils was removed in November. However, the c-analyzer relies on it. To solve that here, we vendor the parts the tool needs so it can be run against 3.12+. (Also see gh-92584.)

Note that we may end up removing this code later in favor of a solution in common with the peg_generator tool (which also relies on distutils).  At the least, the copy here makes sure the c-analyzer tool works on 3.12+ in the meantime.

gh-90110: Fix the c-analyzer Tool (#102483) 
Some incompatible changes had gone in, and the "ignore" lists weren't properly undated. This change fixes that. It's necessary prior to enabling test_check_c_globals, which I hope to do soon.

Note that this does include moving last_resort_memory_error to PyInterpreterState.

gh-89792: Prevent test_tools from copying 1000M of "source" in freeze test (#101837) 
Prevent test_tools from copying 1000M of "source"
    
It doesn't need a git repo, just the checkout.  We skip .git metadata, Doc/build, Doc/venv, and `__pycache__` subdirs, that developers often have in their clients to reduce the size of the source tree copy ten-fold.

This should significantly reduce IO and presumably time on buildbots during this long test.
