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.

4f859ed9c7 Issue 9396. Apply functools.lru_cache in the place of the 
random flushing cache in the re module.
 2010-08-09 04:24:42 +00:00
Gregory P. Smith
5a63183a8b The default size of the re module's compiled regular expression cache has 
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.
