* Add const to several API functions that take char *.Jeremy Hylton2005-12-1020-39/+45
| | | | | | | | | | | | | | | | | | | In C++, it's an error to pass a string literal to a char* function without a const_cast(). Rather than require every C++ extension module to put a cast around string literals, fix the API to state the const-ness. I focused on parts of the API where people usually pass literals: PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type slots, etc. Predictably, there were a large set of functions that needed to be fixed as a result of these changes. The most pervasive change was to make the keyword args list passed to PyArg_ParseTupleAndKewords() to be a const char *kwlist[]. One cast was required as a result of the changes: A type object mallocs the memory for its tp_doc slot and later frees it. PyTypeObject says that tp_doc is const char *; but if the type was created by type_new(), we know it is safe to cast to char *.

| | | | | | | | [ 1346144 ] Segfaults from unaligned loads in floatobject.c by using memcpy and not just blinding casting char* to double*. Thanks to Rune Holm for the report.

| | | | | | | | [ 1327110 ] wrong TypeError traceback in generator expressions by removing the code that can stomp on the users' TypeError raised by the iterable argument to ''.join() -- PySequence_Fast (now?) gives a perfectly reasonable message itself. Also, a couple of tests.
* Merge ast-branch to headJeremy Hylton2005-10-204-11/+461
| | | | | | | | | | This change implements a new bytecode compiler, based on a transformation of the parse tree to an abstract syntax defined in Parser/Python.asdl. The compiler implementation is not complete, but it is in stable enough shape to run the entire test suite excepting two disabled tests.

* Results of a line-by-line comparison back to dictobject.c.Raymond Hettinger2005-08-171-127/+121
| | | | | | | | | | | | * set_merge() cannot assume that the table doesn't resize during iteration. * convert some unnecessary tests to asserts -- they were necessary in dictobject.c because PyDict_Next() is a public function. The same is not true for set_next(). * re-arrange the order of functions to more closely match the order in dictobject.c. This makes it must easier to compare the two and ought to simplify any issues of maintaining both.

Now that generators get close()d during GC, the assertion was being triggered because the generator close() was being called as the top-level frame. However, nothing actually is broken by this; it's just that the condition was unexpected in previous Python versions.

| | | | | | | | | | | | | | | | | | | | | s|=s, s&=s, s-=s, or s^=s). Add related tests. * Improve names for several variables and functions. * Provide alternate table access functions (next, contains, add, and discard) that work with an entry argument instead of just a key. This improves set-vs-set operations because we already have a hash value for each key and can avoid unnecessary calls to PyObject_Hash(). Provides a 5% to 20% speed-up for quick hashing elements like strings and integers. Provides much more substantial improvements for slow hashing elements like tuples or objects defining a custom __hash__() function. * Have difference operations resize() when 1/5 of the elements are dummies. Formerly, it was 1/6. The new ratio triggers less frequently and only in cases that it can resize quicker and with greater benefit. The right answer is probably either 1/4, 1/5, or 1/6. Picked the middle value for an even trade-off between resize time and the space/time costs of dummy entries.
