Serhiy Storchaka added the comment: Here is (conceivably incomplete) list of debugging and tracing output (but not error reporting) from C code.
Controlled output. Import and shutdown details -- controlled by the -v flag. Parser tracing -- controlled by the -d flag. If Py_REF_DEBUG is defined -- controlled by the -X showrefcount flag. If PYMALLOC_DEBUG is defined -- controlled by the PYTHONMALLOCSTATS environment variable. If Py_TRACE_REFS is defined -- controlled by the PYTHONDUMPREFS environment variable. Garbage collecting details -- controlled by gc.set_debug(). If LLTRACE is defined -- controlled by the __ltrace__ global variable. Uncomtrolled output. To stderr: In PyType_ClearCache (Objects/typeobject.c) if MCACHE_STATS is defined. Lists allocations if SHOW_ALLOC_COUNT is defined. Tuples allocations if SHOW_TRACK_COUNT is defined. Interned strings statistics if __INSURE__ is defined. In Python/ceval.c if WITH_TSC is defined. In _PyHash_Fini if Py_HASH_STATS is defined. To stdout: In Modules/_ctypes/malloc_closure.c if MALLOC_CLOSURE_DEBUG is defined. Regex matching trace in Modules/_sre.c if VERBOSE is defined. Statistics in Modules/hashtable.c if Py_DEBUG is defined. Allocation counts if COUNT_ALLOCS is defined. There is also dead code in Parser/parsetok.c, Parser/tokenizer.c, Python/pyarena.c, Python/compile.c, Python/formatter_unicode.c, Modules/_elementtree.c, Modules/_tkinter.c, Objects/unicodeobject.c. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue23034> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
