type.__module__ behavior.
This adds the module name and a dot in front of the type name in every
type object initializer, except for built-in types (and those that
already had this). Note that it touches lots of Mac modules -- I have
no way to test these but the changes look right. Apologies if they're
not. This also touches the weakref docs, which contains a sample type
object initializer. It also touches the mmap test output, because the
mmap type's repr is included in that output. It touches object.h to
put the correct description in a comment.
Apparently this patch (rev 2.41) replaced all the good old "s#"
formats in PyArg_ParseTuple() with "S". Then it did
PyString_FromStringAndSize() to get back the values setup by the
"s#" format. It also incref'd and decref'd the string obtained by
"S" even though the argument tuple had a reference to it.
Replace PyString_AsString() calls with PyString_AS_STRING().
A good rule of thumb -- if you never check the return value of
PyString_AsString() to see if it's NULL, you ought to be using the
macro <wink>.
Many functions used a local variable called return_error, which was
initialized to zero. If an error occurred, it was set to true. Most
of the code paths checked were only executed if return_error was
false. goto is clearer.
The code also seemed to be written under the curious assumption that
calling Py_DECREF() on a local variable would assign the variable to
NULL. As a result, more of the error-exit code paths returned an
object that had a reference count of zero instead of just returning
NULL. Fixed the code to explicitly assign NULL after the DECREF.
A bit more reformatting, but not much.
XXX Need a much better test suite for zlib, since it the current tests
don't exercise any of this broken code.
Mostly by Toby Dickenson and Titus Brown.
Add an optional argument to a decompression object's decompress()
method. The argument specifies the maximum length of the return
value. If the uncompressed data exceeds this length, the excess data
is stored as the unconsumed_tail attribute. (Not to be confused with
unused_data, which is a separate issue.)
Difference from SF patch: Default value for unconsumed_tail is ""
rather than None. It's simpler if the attribute is always a string.
* fixes the zlib decompress sync flush bug as reported in bug #124981
* avoids repeat calls to (in|de)flateEnd when destroying (de)compression
objects
* raises exception when allocating unused_data fails
* fixes memory leak when allocating unused_data fails
* raises exception when allocating decompress data fails
* removes vestigial code from decompress flush now that decompression
returns all available data
* tidies code so object compress/decompress/flush routines are consistent
This involves changing the zlib build process to build zlib itself from sources, then use that library. Also updated are the comments to reflect the new official home of zlib, and add Windows specific notes regarding the build process.
a Z_BUF_ERROR while decompressing. If it is, assume that this means
the data being decompressed is bad and raise an exception, instead of
just assuming that Z_BUF_ERROR always means that more space is required.
and a couple of functions that were missed in the previous batches. Not
terribly tested, but very carefully scrutinized, three times.
All these were found by the little findkrc.py that I posted to python-dev,
which means there might be more lurking. Cases such as this:
long
func(a, b)
long a;
long b; /* flagword */
{
and other cases where the last ; in the argument list isn't followed by a
newline and an opening curly bracket. Regexps to catch all are welcome, of
course ;)
