* Issue #28637: Reapply changeset 223731925d06Victor Stinner2016-11-141-12/+21
| | | | | | | "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.
* Issue #28637: Revert issue #28082, don't import enum in reVictor Stinner2016-11-071-21/+12
| | | | | | 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.

| | | | | | | | | | | | | | | | | | 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.
* | Revert 83784 adding functools.lru_cache() to the re module.Raymond Hettinger2010-08-091-12/+20
| | | | | | | | | | | | | | | | | | | | | | 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.

* | The default size of the re module's compiled regular expression cache hasGregory P. Smith2010-07-271-3/+36
|/ | | | | | | | been increased from 100 to 500 and the cache replacement policy has changed from simply clearing the entire cache on overflow to randomly forgetting 20% of the existing cached compiled regular expressions. This is a performance win for applications that use a lot of regular expressions and limits the impact of the performance hit anytime the cache is exceeded.
