Use per AST-parser state rather than global state to track recursion depth
|
|
within the AST parser to prevent potential race condition due to
|
|
simultaneous parsing.
|
|
|
|
The issue primarily showed up in 3.11 by multithreaded users of
|
|
:func:`ast.parse`. In 3.12 a change to when garbage collection can be
|
|
triggered prevented the race condition from occurring.
