Each such variable falls into one of several +categories: + +* strictly const data +* used exclusively in main or in the REPL +* process-global state (e.g. managing process-level resources + like signals and file descriptors) +* Python "global" runtime state +* per-interpreter runtime state + +The last one can be a problem as soon as anyone creates a second +interpreter (AKA "subinterpreter") in a process. It is definitely a +problem under subinterpreters if they are no longer sharing the GIL, +since the GIL protects us from a lot of race conditions. Keep in mind +that ultimately *all* objects (PyObject) should be treated as +per-interpreter state. This includes "static types", freelists, +_PyIdentifier, and singletons. Take that in for a second. It has +significant implications on where we use static variables! + +Be aware that module-global state (stored in C statics) is a kind of +per-interpreter state. There have been efforts across many years, and +still going, to provide extension module authors mechanisms to store +that state safely (see PEPs 3121, 489, etc.). + +(Note that there has been discussion around support for running multiple +Python runtimes in the same process. That would ends up with the same +problems, relative to static variables, that subinterpreters have.) + +Historically we have been bad at keeping per-interpreter state out of +static variables, mostly because until recently subinterpreters were +not widely used nor even factored in to solutions. However, the +feature is growing in popularity and use in the community. + +Mandate: "Eliminate use of static variables for per-interpreter state." + +The "c-statics.py" script in this directory, along with its accompanying +data files, are part of the effort to resolve existing problems with +our use of static variables and to prevent future problems. + +#------------------------- +## statics for actually-global state (and runtime state consolidation) + +In general, holding any kind of state in static variables +increases maintenance burden and increases the complexity of code (e.g. +we use TSS to identify the active thread state). So it is a good idea +to avoid using statics for state even if for the "global" runtime or +for process-global state. + +Relative to maintenance burden, one problem is where the runtime +state is spread throughout the codebase in dozens of individual +globals. Unlike the other globals, the runtime state represents a set +of values that are constantly shifting in a complex way. When they are +spread out it's harder to get a clear picture of what the runtime +involves. Furthermore, when they are spread out it complicates efforts +that change the runtime. + +Consequently, the globals for Python's runtime state have been +consolidated under a single top-level _PyRuntime global. No new globals +should be added for runtime state. Instead, they should be added to +_PyRuntimeState or one of its sub-structs. The tools in this directory +are run as part of the test suite to ensure that no new globals have +been added. The script can be run manually as well: + + ./python Lib/test/test_c_statics/c-statics.py check + +If it reports any globals then they should be resolved. If the globals +are runtime state then they should be folded into _PyRuntimeState. +Otherwise they should be marked as ignored. diff --git a/Tools/c-analyzer/c_globals/__init__.py b/Tools/c-analyzer/c_globals/__init__.py new file mode 100644 index 00000000000..e69de29bb2d diff --git a/Tools/c-analyzer/c_globals/__main__.py b/Tools/c-analyzer/c_globals/__main__.py new file mode 100644 index 00000000000..9570fb6a14c --- /dev/null +++ b/Tools/c-analyzer/c_globals/__main__.py @@ -0,0 +1,209 @@ +import argparse +import os.path +import re +import sys + +from c_analyzer_common import SOURCE_DIRS, REPO_ROOT +from c_analyzer_common.info import UNKNOWN +from c_analyzer_common.known import ( + from_file as known_from_file, + DATA_FILE as KNOWN_FILE, + ) +from . import find, show +from .supported import is_supported, ignored_from_file, IGNORED_FILE, _is_object + + +def _match_unused_global(variable, knownvars, used): + found = [] + for varid in knownvars: + if varid in used: + continue + if varid.funcname is not None: + continue + if varid.name != variable.name: + continue + if variable.filename and variable.filename != UNKNOWN: + if variable.filename == varid.filename: + found.append(varid) + else: + found.append(varid) + return found + + +def _check_results(unknown, knownvars, used): + badknown = set() + for variable in sorted(unknown): + msg = None + if variable.funcname != UNKNOWN: + msg = f'could not find global symbol {variable.id}' + elif m := _match_unused_global(variable, knownvars, used): + assert isinstance(m, list) + badknown.update(m) + elif variable.name in ('completed', 'id'): #
