* gh-99108: Cleanup references to inexisting `Modules/_blake2`. (GH-126270)Bénédikt Tran2024-11-012-4/+0
| | | | | | | | | * Remove references to `Modules/_blake2`. * Remove `Modules/_blake2` entry from CODEOWNERS The folder does not exist anymore. * Remove `Modules/_blake2` entry from `Tools/c-analyzer/TODO`
* gh-126211: Exclude preprocessor directives from statements containing ↵mpage2024-11-011-1/+1
| | | | | | | | | escaping calls (#126213) The cases generator inserts code to save and restore the stack pointer around statements that contain escaping calls. To find the beginning of such statements, we would walk backwards from the escaping call until we encountered a token that was treated as a statement terminator. This set of terminators should include preprocessor directives.
* gh-90370: Argument Clinic: avoid temporary tuple creation for varargs (#126064)Sergey B Kirpichev2024-10-312-26/+24
| | | | | | | Avoid temporary tuple creation when all arguments either positional-only or vararg. Objects/setobject.c and Modules/gcmodule.c adapted. This fixes slight performance regression for set methods, introduced by gh-115112.
* GH-125498: Update JIT builds to use LLVM 19 and preserve_none (GH-125499)Savannah Ostrowski2024-10-308-75/+52

* gh-124928: Emscripten node support: Clean up old node <= 16 flags (#124929)Hood Chatham2024-10-291-0/+9
| | | | | | Clean up configure flags for old node versions These flags are only needed for node <= 16. Node 16 has been end of life since October of 2023.
* gh-125985: Add free threading scaling micro benchmarks (#125986)Sam Gross2024-10-281-0/+324
| | | | | | | | These consist of a number of short snippets that help identify scaling bottlenecks in the free threaded interpreter. The current bottlenecks are in calling functions in benchmarks that call functions (due to `LOAD_ATTR` not yet using deferred reference counting) and when accessing thread-local data.

* CI: Bump Python to 3.13 and mypy to 1.12 in mypy workflow (#125592)Kirill Podoprigora2024-10-162-4/+2
| | | | | * Bump mypy to 1.12 & Python to 3.13 * Remove unnecessary `type: ignore`
* gh-124872: Replace enter/exit events with "switched" (#125532)Kirill Podoprigora2024-10-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Users want to know when the current context switches to a different context object. Right now this happens when and only when a context is entered or exited, so the enter and exit events are synonymous with "switched". However, if the changes proposed for gh-99633 are implemented, the current context will also switch for reasons other than context enter or exit. Since users actually care about context switches and not enter or exit, replace the enter and exit events with a single switched event. The former exit event was emitted just before exiting the context. The new switched event is emitted after the context is exited to match the semantics users expect of an event with a past-tense name. If users need the ability to clean up before the switch takes effect, another event type can be added in the future. It is not added here because YAGNI. I skipped 0 in the enum as a matter of practice. Skipping 0 makes it easier to troubleshoot when code forgets to set zeroed memory, and it aligns with best practices for other tools (e.g., https://protobuf.dev/programming-guides/dos-donts/#unspecified-enum).

* GH-119866: Spill the stack around escaping calls. (GH-124392)Mark Shannon2024-10-078-381/+1040
| | | | | | | * Spill the evaluation around escaping calls in the generated interpreter and JIT. * The code generator tracks live, cached values so they can be saved to memory when needed. * Spills the stack pointer around escaping calls, so that the exact stack is visible to the cycle GC.
* gh-124889: Remove redundant artificial rules in PEG parser (#124893)efimov-mikhail2024-10-032-47/+50
| | | | | | | | | | | | Cache in C PEG-generator reworked: we save artificial rules in cache by Node string representation as a key instead of Node object itself. As a result total count of artificial rules in parsers.c is lowered from 283 to 170. More natural number ordering is used for the names of artificial rules. Auxiliary method CCallMakerVisitor._generate_artificial_rule_call is added. Its purpose is abstracting work with artificial rules cache. Explicit using of "is_repeat1" kwarg is added to visit_Repeat0 and visit_Repeat1 methods. Its slightly improve code readabitily.

* gh-123923: Defer refcounting for `f_funcobj` in `_PyInterpreterFrame` (#124026)Sam Gross2024-09-242-4/+17
| | | | | | Use a `_PyStackRef` and defer the reference to `f_funcobj` when possible. This avoids some reference count contention in the common case of executing the same code object from multiple threads concurrently in the free-threaded build.
