* Do not build the macOS installer with mimalloc enabled (#112312)Ned Deily2023-11-221-0/+2
| | | | | Do not build the macOS installer with mimalloc enabled pending resolution of weak linking crashes during interpreter startup on macOS 10.9, 10.10, and 10.11 when built on macOS 11 and later.
* gh-59703: restore include of mach-o/dyld.h (gh-112309)Ned Deily2023-11-221-0/+1
| | | | On older versions of macOS, _NSGetExecutablePath appears to only be available via macho-o/dyld so macho-o/dyld.h is still needed.
* Fix docstring and var name of itertools recipe (#112113)Sebastian Rittau2023-11-221-3/+3
| | | | `prepend()` works with arbitrary iterables, not only iterators. In fact, the example given uses a `list`, which is iterable, but not an iterator.

* gh-110950: add upstream Tk fixes to macOS installer. (GH-111041)Christopher Chavez2023-11-217-2/+206
| | | | | | | | | | | | | | | | Add upstream Tk patches for three problems affecting tkinter users: - Update macOS installer to include a fix accepted by upstream Tcl/Tk for a crash encountered after the first :meth:`tkinter.Tk` instance is destroyed. (gh-92603) - Update macOS installer to include an upstream Tcl/Tk fix for the ``ttk::ThemeChanged`` error encountered in Tkinter. (gh-71383) - Update macOS installer to include an upstream Tcl/Tk fix for the ``Secure coding is not enabled for restorable state!`` warning encountered in Tkinter on macOS 14 Sonoma.

* gh-111786: Use separate opcode vars for Tier 1 and Tier 2 (#112289)Michael Droettboom2023-11-201-12/+11
| | | | This makes Windows about 3% faster on pyperformance benchmarks.
* gh-112287: Speed up Tier 2 (uop) interpreter a little (#112286)Guido van Rossum2023-11-207-33/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | This makes the Tier 2 interpreter a little faster. I calculated by about 3%, though I hesitate to claim an exact number. This starts by doubling the trace size limit (to 512), making it more likely that loops fit in a trace. The rest of the approach is to only load `oparg` and `operand` in cases that use them. The code generator know when these are used. For `oparg`, it will conditionally emit ``` oparg = CURRENT_OPARG(); ``` at the top of the case block. (The `oparg` variable may be referenced multiple times by the instructions code block, so it must be in a variable.) For `operand`, it will use `CURRENT_OPERAND()` directly instead of referencing the `operand` variable, which no longer exists. (There is only one place where this will be used.)
* gh-111848: Clean up RESERVE() macro (#112274)Guido van Rossum2023-11-201-14/+9
| | | Also avoid compiler warnings about unused 'reserved' variable.
* gh-106529: Make FOR_ITER a viable uop (#112134)Guido van Rossum2023-11-208-43/+138
| | | | | | | | | | This uses the new mechanism whereby certain uops are replaced by others during translation, using the `_PyUop_Replacements` table. We further special-case the `_FOR_ITER_TIER_TWO` uop to update the deoptimization target to point just past the corresponding `END_FOR` opcode. Two tiny code cleanups are also part of this PR.

* IDLE: Fix test_debugger bug and buildbot failures (#112258)Terry Jan Reedy2023-11-191-5/+7
| | | | | | | | | Missing "requires('gui')" causes Tk() to fail when no gui. This caused CI Hypothesis test to fail, but I did not understand the its error message. Then buildbots failed. IdbTest failed on draft Bdb replacement because so different. Simplified version works on old and new.

* GH-110109: Test pure functionality of `pathlib.Path` user subclasses (#112242)Barney Gale2023-11-181-12/+4
| | | | | | | | | | | Add `PurePathTest` as a superclass of `PathTest`, and therefore also `PathSubclassTest`. This adds coverage of pure functionality in user subclasses of `pathlib.Path`. Remove `PosixPathAsPureTest` and `WindowsPathAsPureTest`, as they now duplicate `PosixPathTest` and `WindowsPathTest`. This makes the MROs of test unit classes match the MROs of pathlib classes.
