Serhiy Storchaka 898ff03e1e bpo-30215: Make re.compile() locale agnostic. (#1361)
Compiled regular expression objects with the re.LOCALE flag no longer
depend on the locale at compile time.  Only the locale at matching
time affects the result of matching.

Serhiy Storchaka 5908300e4b bpo-29995: re.escape() now escapes only special characters. (#1007) 2017-04-13 21:06:43 +03:00
Victor Stinner fb6a6596b5 Issue #28637: Reapply changeset 223731925d06
"issue28082: use IntFlag for re constants" by Ethan Furman.

The re module is not more used in the site module and so adding "import enum"
to re.py doesn't impact python_startup benchmark anymore.

Victor Stinner 1ec1cd161b Issue #28637: Revert issue #28082, don't import enum in re
Importing the enum module in the re module slows down Python startup by 34%
when Python is run from a virtual environment, or more generally when the re
module is imported at startup but not the enum module.

Senthil Kumaran 9f347ea545 reapply the revert made in r83875
Now the _collections is statically built, the build dependencies are in proper
order and build works fine.

Commit Log from r83874:
Issue 9396.   Apply functools.lru_cache in the place of the
random flushing cache in the re module.
2010-08-09 07:30:53 +00:00
Raymond Hettinger 31022301b5 Revert 83784 adding functools.lru_cache() to the re module.
The problem is that the re module is imported by sysconfig
and re needs functools which uses collections.OrderedDict()
but the _collectionsmodule.c code is not yet constructed
at this point in the build.

The likely best solution will be to include _collections
as part of the static build before the rest of the
boot-strapping.
