| * Issue 18719: Remove a false optimizationRaymond Hettinger2013-08-141-9/+0
| | | | | | | | | | | | | | | | | | | | Remove an unused early-out test from the critical path for dict and set lookups. When the strings already have matching lengths, kinds, and hashes, there is no additional information gained by checking the first characters (the probability of a mismatch is already known to be less than 1 in 2**64).

* | Close #17694: Add minimum length to _PyUnicodeWriterVictor Stinner2013-04-171-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | * Add also min_char attribute to _PyUnicodeWriter structure (currently unused) * _PyUnicodeWriter_Init() has no more argument (except the writer itself): min_length and overallocate must be set explicitly * In error handlers, only enable overallocation if the replacement string is longer than 1 character * CJK decoders don't use overallocation anymore * Set min_length, instead of preallocating memory using _PyUnicodeWriter_Prepare(), in many decoders * _PyUnicode_DecodeUnicodeInternal() checks for integer overflow

* | Close #13126: "Simplify" FASTSEARCH() code to help the compiler to emit moreVictor Stinner2013-04-071-3/+5
| | | | | | | | | | | | | | efficient machine code. Patch written by Antoine Pitrou. Without this change, str.find() was 10% slower than str.rfind() in the worst case.
* | Add _PyUnicodeWriter_WriteSubstring() functionVictor Stinner2013-04-021-12/+6
| | | | | | | | | | | | | | | | | | Write a function to enable more optimizations: * If the substring is the whole string and overallocation is disabled, just keep a reference to the string, don't copy characters * Avoid a call to the expensive _PyUnicode_FindMaxChar() function when possible

| | | | | | | | | | | | | | | | | and str.format(args) * Formatting string, int, float and complex use the _PyUnicodeWriter API. It avoids a temporary buffer in most cases. * Add _PyUnicodeWriter_WriteStr() to restore the PyAccu optimization: just keep a reference to the string if the output is only composed of one string * Disable overallocation when formatting the last argument of str%args and str.format(args) * Overallocation allocates at least 100 characters: add min_length attribute to the _PyUnicodeWriter structure * Add new private functions: _PyUnicode_FastCopyCharacters(), _PyUnicode_FastFill() and _PyUnicode_FromASCII() The speed up is around 20% in average.
