commonly used functions to convert an arbitrary binary string into
a hexadecimal digit representation and back again. These are often
(and often differently) implemented in Python. Best to have one
common fast implementation. Specifically,
binascii_hexlify(): a.k.a. b2a_hex() to return the hex representation
of binary data.
binascii_unhexlify(): a.k.a. a2b_hex() to do the inverse conversion
(hex digits to binary data). The argument must have an even length,
and must contain only hex digits, otherwise a TypeError is raised.
after a brief conversation with TP. First, the return values of the
PyString_* function calls should be checked for errors. Second,
bit-manipulations should be used instead of division for spliting the
byte up into its 4 bit digits.
This was a misleading bug -- the true "bug" was that hash(x) gave an error
return when x is an infinity. Fixed that. Added new Py_IS_INFINITY macro to
pyport.h. Rearranged code to reduce growing duplication in hashing of float and
complex numbers, pushing Trent's earlier stab at that to a logical conclusion.
Fixed exceedingly rare bug where hashing of floats could return -1 even if there
wasn't an error (didn't waste time trying to construct a test case, it was simply
obvious from the code that it *could* happen). Improved complex hash so that
hash(complex(x, y)) doesn't systematically equal hash(complex(y, x)) anymore.
string literals has not been tested on an MS_WIN16 platform; the trailing
";" was inside the #ifndef MS_WIN16, which should cause an error (missing
semi-colon) when compiled with that symbol #defined.
resized after creation. 0-length strings are usually shared
and _PyString_Resize() fails on these shared strings.
Fixes [ Bug #111667 ] unicode core dump.
This is an enhancement to a prior patch (100941) ...
[T]his patch removes the risk of deadlock waiting for the child previously present in certain cases. It adds tracking of all file handles returned from an os.popen* call and only waits for the child process, returning the exit code, on the closure of the final file handle to that child.
by Edward K. Ream <edream@users.sourceforge.net> about FILE* values and
incompatible C libraries in dynamically linked extensions. It is not clear
(to me) how realistic the issue is, but it is better documented than not.
This closes SourceForge bug #111520.
* use self.debug_print() for debug messages
* uses now copy.copy() to copy lists
* added 'shared_lib_extension=".dll"', ... , this is necessary if you
want use the compiler class outside of the standard distutils build
process.
* changed result type of check_config_h() from int to string
Properly end a comment block. It was terminated fine later but by a subsequent
block and. It was also in #if 0. This patch is so trivial I can't believe I am
talking about it. :)
and fwrite return size_t, so it is safer to cast up to the largest type for the
comparison. I believe the cast is required at all to remove compiler warnings.
- fix tab space issues (SF patch #101167 by Neil Schemenauer)
- fix co_flags for classes to include CO_NEWLOCALS (SF patch #101145 by Neil)
- fix for merger of UNPACK_LIST and UNPACK_TUPLE into UNPACK_SEQUENCE,
(SF patch #101168 by, well, Neil :)
- Adjust bytecode MAGIC to current bytecode.
