the sentinel value in the main function, rather than the helper. This
function could possibly do with an early-out if any of the helper calls ends
up with a len of 0, but I doubt it really matters (how common are malformed
hangul syllables, really?)
posix__getfullpathname().
In partial answer to the now-deleted XXX comment:
/* XXX(twouters) Why use 'et#' here at all? insize isn't used */
`insize` is an input parameter too, and it was left uninitialized,
leading to seemingly random failures.
non-32bit platforms. Will still only allow 32 bits in a timestamp on Win64,
but at least it won't crash, and it'll work right on platforms where longs
are big enough to contain time_t's.
(A better-working, although conceptually less-right fix would have been to
use Py_ssize_t here, but Martin and Tim won't let me.)
- New semantics for __exit__() -- it must re-raise the exception
if type is not None; the with-statement itself doesn't do this.
(See the updated PEP for motivation.)
- Added context managers to:
- file
- thread.LockType
- threading.{Lock,RLock,Condition,Semaphore,BoundedSemaphore}
- decimal.Context
- Added contextlib.py, which defines @contextmanager, nested(), closing().
- Unit tests all around; bot no docs yet.
- IMPORT_NAME takes an extra argument from the stack: the relativeness of
the import. Only passed to __import__ when it's not -1.
- __import__() takes an optional 5th argument for the same thing; it
__defaults to -1 (old semantics: try relative, then absolute)
- 'from . import name' imports name (be it module or regular attribute)
from the current module's *package*. Likewise, 'from .module import name'
will import name from a sibling to the current module.
- Importing from outside a package is not allowed; 'from . import sys' in a
toplevel module will not work, nor will 'from .. import sys' in a
(single-level) package.
- 'from __future__ import absolute_import' will turn on the new semantics
for import and from-import: imports will be absolute, except for
from-import with dots.
Includes tests for regular imports and importhooks, parser changes and a
NEWS item, but no compiler-package changes or documentation changes.
- The copy module now "copies" function objects (as atomic objects).
- dict.__getitem__ now looks for a __missing__ hook before raising
KeyError.
- Added a new type, defaultdict, to the collections module.
This uses the new __missing__ hook behavior added to dict (see above).
On a box where sizeof(size_t) == 4, C doesn't define
what happens when a size_t value is shifted right by
32 bits, and this caused test_mmap to fail on Windows
in a debug build. So use different code to break
the size apart depending on how large size_t actually
is.
This looks like an illusion, since lots of code in this
module still appears to assume sizes can't be more
than 32 bits (e.g., the internal _GetMapSize() still
returns an int), but at least test_mmap passes again.
has been applied fairly arbitrarily in this module (nsmallest uses
Py_ssize_t, nlargest does not) and it probably deserves a more complete
review. Fixes heapq.nsmallest() always returning the empty list (on
platforms with 64-bit ssize_t/long)
