| | | | | We can't move it to _PyRuntimeState because the symbol is exposed in the stable ABI. We'll have to sort that out before a per-interpreter GIL, but it shouldn't be too hard. https://github.com/python/cpython/issues/81057

* gh-88500: Reduce memory use of `urllib.unquote` (#96763)Gregory P. Smith2022-12-113-11/+23
| | | | | | | | | | | `urllib.unquote_to_bytes` and `urllib.unquote` could both potentially generate `O(len(string))` intermediate `bytes` or `str` objects while computing the unquoted final result depending on the input provided. As Python objects are relatively large, this could consume a lot of ram. This switches the implementation to using an expanding `bytearray` and a generator internally instead of precomputed `split()` style operations. Microbenchmarks with some antagonistic inputs like `mess = "\u0141%%%20a%fe"*1000` show this is 10-20% slower for unquote and unquote_to_bytes and no different for typical inputs that are short or lack much unicode or % escaping. But the functions are already quite fast anyways so not a big deal. The slowdown scales consistently linear with input size as expected. Memory usage observed manually using `/usr/bin/time -v` on `python -m timeit` runs of larger inputs. Unittesting memory consumption is difficult and does not seem worthwhile. Observed memory usage is ~1/2 for `unquote()` and <1/3 for `unquote_to_bytes()` using `python -m timeit -s 'from urllib.parse import unquote, unquote_to_bytes; v="\u0141%01\u0161%20"*500_000' 'unquote_to_bytes(v)'` as a test.

* GH-98831: Typed stack effects, and more instructions converted (#99764)Guido van Rossum2022-12-084-604/+545
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Stack effects can now have a type, e.g. `inst(X, (left, right -- jump/uint64_t)) { ... }`. Instructions converted to the non-legacy format: * COMPARE_OP * COMPARE_OP_FLOAT_JUMP * COMPARE_OP_INT_JUMP * COMPARE_OP_STR_JUMP * STORE_ATTR * DELETE_ATTR * STORE_GLOBAL * STORE_ATTR_INSTANCE_VALUE * STORE_ATTR_WITH_HINT * STORE_ATTR_SLOT, and complete the store_attr family * Complete the store_subscr family: STORE_SUBSCR{,DICT,LIST_INT} (STORE_SUBSCR was alread half converted, but wasn't using cache effects yet.) * DELETE_SUBSCR * PRINT_EXPR * INTERPRETER_EXIT (a bit weird, ends in return) * RETURN_VALUE * GET_AITER (had to restructure it some) The original had mysterious `SET_TOP(NULL)` before `goto error`. I assume those just account for `obj` having been decref'ed, so I got rid of them in favor of the cleanup implied by `ERROR_IF()`. * LIST_APPEND (a bit unhappy with it) * SET_ADD (also a bit unhappy with it) Various other improvements/refactorings as well.

| | | | | | When checking for auto() instances, only top-level usage is supported, which means either alone or as part of a regular tuple. Other containers, such as lists, dicts, or namedtuples, will not have auto() transformed into a value.
* gh-98030: socket: add missing TCP socket options (#98031)Matthieu Baerts2022-12-083-4/+78
| | | | | | | | | | | | | A few TCP socket options have been added to the Linux kernel these last few years. This commit adds all the ones available in Linux 6.0: https://elixir.bootlin.com/linux/v6.0/source/include/uapi/linux/tcp.h#L91 While at it, the TCP_FASTOPEN option has been moved lower in the list just to keep the same order as in tcp.h to ease future synchronisations.
