Serhiy Storchaka 9305d83425 Issue #26754: PyUnicode_FSDecoder() accepted a filename argument encoded as

Victor Stinner 3cdd5fb970 code_richcompare() now uses the constants types
Issue #25843: When compiling code, don't merge constants if they are equal but
have a different types. For example, "f1, f2 = lambda: 1, lambda: 1.0" is now
correctly compiled to two different functions: f1() returns 1 (int) and f2()
returns 1.0 (int), even if 1 and 1.0 are equal.

Add a new _PyCode_ConstantKey() private function.

Martin Panter eeb896c411 Issue #24802: Copy bytes-like objects to null-terminated buffers if necessary
This avoids possible buffer overreads when int(), float(), compile(), exec()
and eval() are passed bytes-like objects. Similar code is removed from the
complex() constructor, where it was not reachable.

Patch by John Leitch, Serhiy Storchaka and Martin Panter.

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.

Georg Brandl 1a3284ed69 #1535: rename __builtin__ module to builtins. 2007-12-02 09:40:06 +00:00
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.
2007-11-06 21:34:58 +00:00
Georg Brandl bd1c68c94f Patch #1303: Adapt str8 constructor to bytes (now buffer) one. 2007-10-24 18:55:37 +00:00
Brett Cannon 4043001f5d Make str/str8 comparisons return True/False for !=/==.
Code that has been returning str8 becomes much more apparent thanks to this
(e.g., struct module returning str8 for all string-related formats or sqlite3
passing in str8 instances when converting objects that had a __conform__
method).  One also has to watch out in C code when making a key from char *
using PyString in the C code but a str instance in Python code as that will not
longer compare equal.

Once str8 gains a constructor like the current bytes type then
test_modulefinder needs a cleanup as the fix is a little messy in that file.

Thanks goes to Thomas Lee for writing the patch for the change giving an
initial run-down of why most of the tests were failing.
