cpython-lru_cache-weakref: Python/ceval.c annotate

annotate Python/ceval.c @ 61184:4fd3ab5fa71d

Make (most of) Python's tests pass under Thread Sanitizer. http://code.google.com/p/data-race-test/wiki/ThreadSanitizer is a dynamic data race detector that runs on top of valgrind. With this patch, the binaries at http://code.google.com/p/data-race-test/wiki/ThreadSanitizer#Binaries pass many but not all of the Python tests. All of regrtest still passes outside of tsan. I've implemented part of the C1x atomic types so that we can explicitly mark variables that are used across threads, and get defined behavior as compilers advance. I've added tsan's client header and implementation to the codebase in dynamic_annotations.{h,c} (docs at http://code.google.com/p/data-race-test/wiki/DynamicAnnotations). Unfortunately, I haven't been able to get helgrind and drd to give sensible error messages, even when I use their client annotations, so I'm not supporting them.

75009d4863c9 Merged revisions 68460 via svnmerge from Benjamin Peterson <benjamin@python.org> parents: 50211 diff changeset	581
75009d4863c9 Merged revisions 68460 via svnmerge from Benjamin Peterson <benjamin@python.org> parents: 50211 diff changeset	582 (1) is very unlikely because typically signal delivery
75009d4863c9 Merged revisions 68460 via svnmerge from Benjamin Peterson <benjamin@python.org> parents: 50211 diff changeset	583 is blocked during signal handling. So it should be impossible.
75009d4863c9 Merged revisions 68460 via svnmerge from Benjamin Peterson <benjamin@python.org> parents: 50211 diff changeset	584 (2) is a real possibility.

e7c6a18381d9 * Python/ceval.c (eval_code): added registry of pending functions Guido van Rossum <guido@python.org> parents: 1846 diff changeset	586 The safety against (2) is derived from the fact that only one
