* Make identifiers str (not str8) objects throughout.Martin v. Löwis2007-06-101-2/+2
| | | | | | | | | | | | | | | | | | | This affects the parser, various object implementations, and all places that put identifiers into C string literals. In testing, a number of crashes occurred as code would fail when the recursion limit was reached (such as the Unicode interning dictionary having key/value pairs where key is not value). To solve these, I added an overflowed flag, which allows for 50 more recursions after the limit was reached and the exception was raised, and a recursion_critical flag, which indicates that recursion absolutely must be allowed, i.e. that a certain call must not cause a stack overflow exception. There are still some places where both str and str8 are accepted as identifiers; these should eventually be removed.

Use a bit in tp_flags for each common builtin type. Check the bit to determine if any instance is a subclass of these common types. The check avoids a function call and O(n) search of the base classes. The check is done in the various Py*_Check macros rather than calling PyType_IsSubtype(). All the bits are set in tp_flags when the type is declared in the Objects/*object.c files because PyType_Ready() is not called for all the types. Should PyType_Ready() be called for all types? If so and the change is made, the changes to the Objects/*object.c files can be reverted (remove setting the tp_flags). Objects/typeobject.c would also have to be modified to add conditions for Py*_CheckExact() in addition to each the PyType_IsSubtype check. ........

* Wrote down the invariants of some common objects whose structure isArmin Rigo2004-10-281-0/+9
| | | | | | | | | | exposed in header files. Fixed a few comments in these headers. As we might have expected, writing down invariants systematically exposed a (minor) bug. In this case, function objects have a writeable func_code attribute, which could be set to code objects with the wrong number of free variables. Calling the resulting function segfaulted the interpreter. Added a corresponding test.

| | | | | | | | interning. I modified Oren's patch significantly, but the basic idea and most of the implementation is unchanged. Interned strings created with PyString_InternInPlace() are now mortal, and you must keep a reference to the resulting string around; use the new function PyString_InternImmortal() to create immortal interned strings.

* PyString_FromFormat() and PyString_FromFormatV(): Largely ripped fromBarry Warsaw2001-08-241-0/+4
| | | | | | | | | | | | | | | | | | | PyErr_Format() these new C API methods can be used instead of sprintf()'s into hardcoded char* buffers. This allows us to fix many situation where long package, module, or class names get truncated in reprs. PyString_FromFormat() is the varargs variety. PyString_FromFormatV() is the va_list variety Original PyErr_Format() code was modified to allow %p and %ld expansions. Many reprs were converted to this, checkins coming soo. Not changed: complex_repr(), float_repr(), float_print(), float_str(), int_repr(). There may be other candidates not yet converted. Closes patch #454743.
* SF bug 433228: repr(list) woes when len(list) big.Tim Peters2001-06-161-0/+4
| | | | | | | | | | | | Gave Python linear-time repr() implementations for dicts, lists, strings. This means, e.g., that repr(range(50000)) is no longer 50x slower than pprint.pprint() in 2.2 <wink>. I don't consider this a bugfix candidate, as it's a performance boost. Added _PyString_Join() to the internal string API. If we want that in the public API, fine, but then it requires runtime error checks instead of asserts.
* Patch #424335: Implement string_richcompare, remove string_compare.Martin v. Löwis2001-05-241-0/+1
| | | | Use new _PyString_Eq in lookdict_string.
* This patch changes the way the string .encode() method works slightlyMarc-André Lemburg2001-05-151-3/+40
| | | | | | | | | | | | | | | | | | | | | | | | | and introduces a new method .decode(). The major change is that strg.encode() will no longer try to convert Unicode returns from the codec into a string, but instead pass along the Unicode object as-is. The same is now true for all other codec return types. The underlying C APIs were changed accordingly. Note that even though this does have the potential of breaking existing code, the chances are low since conversion from Unicode previously took place using the default encoding which is normally set to ASCII rendering this auto-conversion mechanism useless for most Unicode encodings. The good news is that you can now use .encode() and .decode() with much greater ease and that the door was opened for better accessibility of the builtin codecs. As demonstration of the new feature, the patch includes a few new codecs which allow string to string encoding and decoding (rot13, hex, zip, uu, base64). Written by Marc-Andre Lemburg.

* _Py_ReleaseInternedStrings(): Private API function to decref andBarry Warsaw2001-02-231-0/+2
| | | | | | release the interned string dictionary. This is useful for memory use debugging because it eliminates a huge source of noise from the reports. Only defined when INTERN_STRINGS is defined.
* Derived from Martin's SF patch 110609: support unbounded ints in ↵Tim Peters2000-09-211-0/+2
| | | | | | | | | | | | | | | | %d,i,u,x,X,o formats. Note a curious extension to the std C rules: x, X and o formatting can never produce a sign character in C, so the '+' and ' ' flags are meaningless for them. But unbounded ints *can* produce a sign character under these conversions (no fixed- width bitstring is wide enough to hold all negative values in 2's-comp form). So these flags become meaningful in Python when formatting a Python long which is too big to fit in a C long. This required shuffling around existing code, which hacked x and X conversions to death when both the '#' and '0' flags were specified: the hacks weren't strong enough to deal with the simultaneous possibility of the ' ' or '+' flags too, since signs were always meaningless before for x and X conversions. Isomorphic shuffling was required in unicodeobject.c. Also added dozens of non-trivial new unbounded-int test cases to test_format.py.
* This patch adds a new Python C API called PyString_AsStringAndSize()Marc-André Lemburg2000-09-191-0/+15
| | | | | | | | | | | | | which implements the automatic conversion from Unicode to a string object using the default encoding. The new API is then put to use to have eval() and exec accept Unicode objects as code parameter. This closes bugs #110924 and #113890. As side-effect, the traditional C APIs PyString_Size() and PyString_AsString() will also accept Unicode objects as parameters.

* Two speedup hacks. Caching the hash saves recalculation of a string'sGuido van Rossum1997-01-181-3/+23
| | | | | | | | | | hash value. Interning strings (which requires hash caching) tries to ensure that only one string object with a given value exists, so equality tests are one pointer comparison. Together, these can speed the interpreter up by as much as 20%. Each costs the size of a long or pointer per string object. In addition, interned strings live until the end of times. If you are concerned about memory footprint, simply comment the #define out here (and rebuild everything!).
