test_peg_generator now defines the _Py_TEST_PEGEN macro to specialize
Python-ast.c, rather than relying on Py_BUILD_CORE.

Python-ast.c can now also includes pycore_ast_state.h when built by
test_peg_generator. The test now also builds it with the
Py_BUILD_CORE macro defined.

I am not super happy with this approach. I don't think we should introduce test-dependent macros in the actual codebase. In any case, if there isn't a simpler solution...then we can go ahead I suppose (I don't want to block only on this).

bpo-43244: Fix test_peg_generator for PyAST_Validate() …
0543fc1 
test_peg_generator now defines _Py_TEST_PEGEN macro when building C
code to not call PyAST_Validate() in Parser/pegen.c. Moreover, it
defines Py_BUILD_CORE_MODULE macro to get access to the internal
C API.

Remove "global_ast_state" from Python-ast.c when it's built by
test_peg_generator: get the AST state from the current interpreter.

I am not super happy with this approach. I don't think we should introduce test-dependent macros in the actual codebase. In any case, if there isn't a simpler solution...then we can go ahead I suppose (I don't want to block only on this).

The first version of PR didn't introduce code specific to test_peg_generator, I already added in commit 5cf4782. It only renamed the #ifdef.

My problem was SystemError: impossible module node error. In fact, the error comes from Parser/pegen.c which only calls PyAST_Validate() if Py_BUILD_CORE macro is defined.

I rewrote my PR to restrict the #ifdef to a single line in Parser/pegen.c. It sounds less surprising that test_peg_generator is related to Parser/pegen.c rather than Python/Python-ast.c.

My first approach avoided Py_BUILD_CORE by any mean to work around the SystemError: impossible module node error.

Hi! The buildbot AMD64 Windows10 3.x has failed when building commit e0bf70d.

What do you need to do:

  1. Don't panic.
  2. Check the buildbot page in the devguide if you don't know what the buildbots are or how they work.
  3. Go to the page of the buildbot that failed (https://buildbot.python.org/all/#builders/146/builds/958) and take a look at the build logs.
  4. Check if the failure is related to this commit (e0bf70d) or if it is a false positive.
  5. If the failure is related to this commit, please, reflect that on the issue and make a new Pull Request with a fix.

You can take a look at the buildbot page here:
