* bpo-46020: Optimize long_pow for the common case (GH-30555)Tim Peters2022-01-121-6/+13
| | | | This cuts a bit of overhead by not initializing the table of small odd powers unless it's needed for a large exponent.
* bpo-45953: Statically allocate and initialize global bytes objects. (gh-30096)Eric Snow2022-01-111-78/+14
| | | | | The empty bytes object (b'') and the 256 one-character bytes objects were allocated at runtime init. Now we statically allocate and initialize them. https://bugs.python.org/issue45953
* bpo-46235: Do all ref-counting at once during list/tuple multiplication ↵Dennis Sweeney2022-01-082-26/+48
| | | | | | | | | | (GH-30346) When multiplying lists and tuples by `n`, increment each element's refcount, by `n`, just once. Saves `n-1` increments per element, and allows for a leaner & faster copying loop. Code by sweeneyde (Dennis Sweeney).
* bpo-46006: Revert "bpo-40521: Per-interpreter interned strings (GH-20085)" ↵Victor Stinner2022-01-062-19/+69
| | | | | | | | | | | (GH-30422) This reverts commit ea251806b8dffff11b30d2182af1e589caf88acf. Keep "assert(interned == NULL);" in _PyUnicode_Fini(), but only for the main interpreter. Keep _PyUnicode_ClearInterned() changes avoiding the creation of a temporary Python list object.

| | | | | | * bpo-46202: remove opcode POP_EXCEPT_AND_RERAISE * do not assume that an exception group is truthy
* bpo-46233: Minor speedup for bigint squaring (GH-30345)Tim Peters2022-01-041-5/+19
| | | | | | | x_mul()'s squaring code can do some redundant and/or useless work at the end of each digit pass. A more careful analysis of worst-case carries at various digit positions allows making that code leaner.
* bpo-46219, 46221: simplify except* implementation following exc_info ↵Irit Katriel2022-01-021-2/+118
| | | | changes. Move helpers to exceptions.c. Do not assume that exception groups are truthy. (GH-30289)
* bpo-46218: Change long_pow() to sliding window algorithm (GH-30319)Tim Peters2022-01-021-24/+84
| | | | | | | | | | | * bpo-46218: Change long_pow() to sliding window algorithm The primary motivation is to eliminate long_pow's reliance on that the number of bits in a long "digit" is a multiple of 5. Now it no longer cares how many bits are in a digit. But the sliding window approach also allows cutting the precomputed table of small powers in half, which reduces initialization overhead enough that the approach pays off for smaller exponents too. Depending on exponent bit patterns, a sliding window may also be able to save some bigint multiplies (sometimes when at least 5 consecutive exponent bits are 0, regardless of their starting bit position modulo 5). Note: boosting the window width to 6 didn't work well overall. It give marginal speed improvements for huge exponents, but the increased overhead (the small-power table needs twice as many entries) made it a loss for smaller exponents.

* bpo-45953: Statically initialize the small ints. (gh-30092)Eric Snow2021-12-141-29/+0
| | | | | | | The array of small PyLong objects has been statically declared. Here I also statically initialize them. Consequently they are no longer initialized dynamically during runtime init. I've also moved them under a new sub-struct in _PyRuntimeState, in preparation for static allocation and initialization of other global objects. https://bugs.python.org/issue45953

* bpo-46008: Make runtime-global object/type lifecycle functions and state ↵Eric Snow2021-12-0911-72/+193
| | | | | | | | | | | | consistent. (gh-29998) This change is strictly renames and moving code around. It helps in the following ways: * ensures type-related init functions focus strictly on one of the three aspects (state, objects, types) * passes in PyInterpreterState * to all those functions, simplifying work on moving types/objects/state to the interpreter * consistent naming conventions help make what's going on more clear * keeping API related to a type in the corresponding header file makes it more obvious where to look for it https://bugs.python.org/issue46008
