Patch by Serhiy Storchaka.

Marc-André Lemburg 8f36af7a4c Normalize the encoding names for Latin-1 and UTF-8 to
'latin-1' and 'utf-8'.

These are optimized in the Python Unicode implementation
to result in more direct processing, bypassing the codec
registry.

Also see issue11303.

Antoine Pitrou fd036451bf #2834: Change re module semantics, so that str and bytes mixing is forbidden,
and str (unicode) patterns get full unicode matching by default. The re.ASCII
flag is also introduced to ask for ASCII matching instead.

Antoine Pitrou 22628c4d6a #3231: re.compile fails with some bytes patterns 2008-07-22 17:53:22 +00:00
Thomas Wouters 40a088dc27 Fix 're' to work on bytes. It could do with a few more tests, though. 2008-03-18 20:19:54 +00:00
Christian Heimes a37d4c693a Removed PyInt_GetMax and sys.maxint
I replaced sys.maxint with sys.maxsize in Lib/*.py. Does anybody see a problem with the change on Win 64bit platforms? Win 64's long is just 32bit but the sys.maxsize is now 2**63-1 on every 64bit platform.
Also added docs for sys.maxsize.

Guido van Rossum 98297ee781 Merging the py3k-pep3137 branch back into the py3k branch.
No detailed change log; just check out the change log for the py3k-pep3137
branch.  The most obvious changes:

  - str8 renamed to bytes (PyString at the C level);
  - bytes renamed to buffer (PyBytes at the C level);
  - PyString and PyUnicode are no longer compatible.

I.e. we now have an immutable bytes type and a mutable bytes type.

The behavior of PyString was modified quite a bit, to make it more
bytes-like.  Some changes are still on the to-do list.

Guido van Rossum 75a902db78 Patch 1280, by Alexandre Vassalotti.
