They do need to be properly quoted when serialized to text, though. - Verify that email headers are well-formed This should fail for custom fold() implementations that aren't careful about newlines.

| | | | | | | When builtin static types are initialized for a subinterpreter, various "tp" slots have already been inherited (for the main interpreter). This was interfering with the logic in add_operators() (in Objects/typeobject.c), causing a wrapper to get created when it shouldn't. This change fixes that by preserving the original data from the static type struct and checking that.

* [3.12] gh-117983: Defer import of threading for lazy module loading ↵Miss Islington (bot)2024-07-031-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (GH-120233) (GH-121350) gh-117983: Defer import of threading for lazy module loading (GH-120233) As noted in gh-117983, the import importlib.util can be triggered at interpreter startup under some circumstances, so adding threading makes it a potentially obligatory load. Lazy loading is not used in the stdlib, so this removes an unnecessary load for the majority of users and slightly increases the cost of the first lazily loaded module. An obligatory threading load breaks gevent, which monkeypatches the stdlib. Although unsupported, there doesn't seem to be an offsetting benefit to breaking their use case. For reference, here are benchmarks for the current main branch: ``` ❯ hyperfine -w 8 './python -c "import importlib.util"' Benchmark 1: ./python -c "import importlib.util" Time (mean ± σ): 9.7 ms ± 0.7 ms [User: 7.7 ms, System: 1.8 ms] Range (min … max): 8.4 ms … 13.1 ms 313 runs ``` And with this patch: ``` ❯ hyperfine -w 8 './python -c "import importlib.util"' Benchmark 1: ./python -c "import importlib.util" Time (mean ± σ): 8.4 ms ± 0.7 ms [User: 6.8 ms, System: 1.4 ms] Range (min … max): 7.2 ms … 11.7 ms 352 runs ``` Compare to: ``` ❯ hyperfine -w 8 './python -c pass' Benchmark 1: ./python -c pass Time (mean ± σ): 7.6 ms ± 0.6 ms [User: 5.9 ms, System: 1.6 ms] Range (min … max): 6.7 ms … 11.3 ms 390 runs ``` This roughly halves the import time of importlib.util.

* [3.12] gh-121018: Fix more cases of exiting in argparse when ↵Serhiy Storchaka2024-06-281-2/+3
| | | | | | | | | | exit_on_error=False (GH-121056) (GH-121129) * parse_intermixed_args() now raises ArgumentError instead of calling error() if exit_on_error is false. * Internal code now always raises ArgumentError instead of calling error(). It is then caught at the higher level and error() is called if exit_on_error is true. (cherry picked from commit 81a654a3425eaa05a51342509089533c1f623f1b)

* [3.12] gh-105623 Fix performance degradation in logging RotatingFileHandler ↵Miss Islington (bot)2024-06-281-0/+2
| | | | | | | | | | | | | (GH-105887) (GH-121116) The check for whether the log file is a real file is expensive on NFS filesystems. This commit reorders the rollover condition checking to not do the file type check if the expected file size is less than the rotation threshold.
