This uses up to 12.5% overallocation, not entirely unlike list_resize().
Could probably use more tweaks for odd allocation patterns, TBD.
Also add __alloc__() method which returns the actually allocated size.
PS. I'm now convinced that we need something like "".join(); later.
number of tests, all because of the codecs/_multibytecodecs issue described
here (it's not a Py3K issue, just something Py3K discovers):
http://mail.python.org/pipermail/python-dev/2006-April/064051.html
Hye-Shik Chang promised to look for a fix, so no need to fix it here. The
tests that are expected to break are:
test_codecencodings_cn
test_codecencodings_hk
test_codecencodings_jp
test_codecencodings_kr
test_codecencodings_tw
test_codecs
test_multibytecodec
This merge fixes an actual test failure (test_weakref) in this branch,
though, so I believe merging is the right thing to do anyway.
(branch-creation time) up to 43067. 43068 and 43069 contain a little
swapping action between re.py and sre.py, and this mightily confuses svn
merge, so later changes are going in separately.
This merge should break no additional tests.
The last-merged revision is going in a 'last_merge' property on '.' (the
branch directory.) Arbitrarily chosen, really; if there's a BCP for this, I
couldn't find it, but we can easily change it afterwards ;)
- all classes are new-style (but ripping out classobject.[ch] isn't done)
- int/int -> float
- all exceptions must derive from BaseException
- absolute import
- 'as' and 'with' are keywords
PyObject_Unicode(). This problem was originally reported from Coverity
and addresses mail on python-dev "checkin r43015".
This inlines the conversion of the string to unicode and cleans
up/simplifies some code at the end of the PyObject_Unicode().
We really need a complete C API test module for all public APIs
and passing good and bad parameter values.
Will backport.
there)
- Add missing DECREFs of inner-scope 'temp' variable
- Add various missing DECREFs by changing 'return NULL' into 'goto onError'
- Avoid double DECREF when last _PyUnicode_Resize() fails
Coverity found one of the missing DECREFs, but oddly enough not the others.
Anyway, this is the changes to the with-statement
so that __exit__ must return a true value in order
for a pending exception to be ignored.
The PEP (343) is already updated.
added message attribute compared to the previous version of Exception. It is
also a new-style class, making all exceptions now new-style. KeyboardInterrupt
and SystemExit inherit from BaseException directly. String exceptions now
raise DeprecationWarning.
Applies patch 1104669, and closes bugs 1012952 and 518846.
- 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.
- 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).
Py_SAFE_DOWNCAST can evaluate its first argument multiple
times in a debug build. This caused two distinct assert-
failures in test_unicode run under a debug build. Rewrote
the code in trivial ways so that multiple evaluation of the
first argument doesn't hurt.
* Allow the 3rd argument to generator.throw() to be None.
The 'raise' statement does the same, and anyway it follows the
general policy that optional arguments of built-ins should, when
reasonable, have a default value specifiable from Python.
readline/readlines/read/readinto, loudly break by raising ValueError, rather
than silently deliver data out of order or hitting EOF prematurely.
Probably not a bugfix candidate, even though it affects no 'working' code.
