* gh-101169: reduce the implementation of except* by one bytecode instruction ↵Irit Katriel2023-01-191-16/+11

* gh-59956: Clarify GILState-related Code (gh-101161)Eric Snow2023-01-1910-250/+373
| | | | | | | | | | The objective of this change is to help make the GILState-related code easier to understand. This mostly involves moving code around and some semantically equivalent refactors. However, there are a also a small number of slight changes in structure and behavior: * tstate_current is moved out of _PyRuntimeState.gilstate * autoTSSkey is moved out of _PyRuntimeState.gilstate * autoTSSkey is initialized earlier * autoTSSkey is re-initialized (after fork) earlier https://github.com/python/cpython/issues/59956

* GH-98831: Implement array support in cases generator (#100912)Guido van Rossum2023-01-176-177/+398
| | | | | | | | You can now write things like this: ``` inst(BUILD_STRING, (pieces[oparg] -- str)) { ... } inst(LIST_APPEND, (list, unused[oparg-1], v -- list, unused[oparg-1])) { ... } ``` Note that array output effects are only partially supported (they must be named `unused` or correspond to an input effect).

* gh-94518: [_posixsubprocess] Replace variable validity flags with reserved ↵Oleg Iarygin2023-01-142-33/+32
| | | | | | | | | | | | | values (#94687) Have _posixsubprocess.c stop using boolean flags to say if gid and uid values were supplied and action is required. Such an implicit "either initialized or look somewhere else" confused both the reader (another mental connection to constantly track between functions) and a compiler (warnings on potentially uninitialized variables being passed). Instead, we can utilize a special group/user id as a flag value -1 defined by POSIX but used nowhere else. Namely: gid: call_setgid = False → gid = -1 uid: call_setuid = False → uid = -1 groups: call_setgroups = False → groups = NULL (obtained with (groups_list != Py_None) ? groups : NULL) This PR is required for #94519.

| | | | | | Fix the gdbm_compat library detection logic to actually check for -lgdbm_compat independently of the ndbm detection. This fixes the build failure with `--with-dbmliborder=gdbm`, and implicit fallback to ndbm with the default value.

| | | These tests become flaky when py.exe exists on the test machine but isn't the one that was just built. They also don't provide any useful information for this scenario, so easiest to just skip them.
