* gh-116322: Add Py_mod_gil module slot (#116882)Brett Simmers2024-05-03102-32/+200
| | | | | | | | | | | | | | This PR adds the ability to enable the GIL if it was disabled at interpreter startup, and modifies the multi-phase module initialization path to enable the GIL when loading a module, unless that module's spec includes a slot indicating it can run safely without the GIL. PEP 703 called the constant for the slot `Py_mod_gil_not_used`; I went with `Py_MOD_GIL_NOT_USED` for consistency with gh-104148. A warning will be issued up to once per interpreter for the first GIL-using module that is loaded. If `-v` is given, a shorter message will be printed to stderr every time a GIL-using module is loaded (including the first one that issues a warning).

* gh-82062: Fix support of parameter defaults on methods in extension modules ↵Sergey B Kirpichev2024-05-021-0/+10
| | | | | | | | | (GH-115270) Now inspect.signature() supports references to the module globals in parameter defaults on methods in extension modules. Previously it was only supported in functions. The workaround was to specify the fully qualified name, including the module name.

* gh-110850: Add PyTime_TimeRaw() function (#118394)Victor Stinner2024-05-011-0/+60
| | | | | | | | | | | | | | | | | Add "Raw" variant of PyTime functions: * PyTime_MonotonicRaw() * PyTime_PerfCounterRaw() * PyTime_TimeRaw() Changes: * Add documentation and tests. Tests release the GIL while calling raw clock functions. * py_get_system_clock() and py_get_monotonic_clock() now check that the GIL is hold by the caller if raise_exc is non-zero. * Reimplement "Unchecked" functions with raw clock functions.

* gh-118335: Configure Tier 2 interpreter at build time (#118339)Guido van Rossum2024-05-012-1/+18
| | | | | | | | | | | | | | | | | | | | | | The code for Tier 2 is now only compiled when configured with `--enable-experimental-jit[=yes|interpreter]`. We drop support for `PYTHON_UOPS` and -`Xuops`, but you can disable the interpreter or JIT at runtime by setting `PYTHON_JIT=0`. You can also build it without enabling it by default using `--enable-experimental-jit=yes-off`; enable with `PYTHON_JIT=1`. On Windows, the `build.bat` script supports `--experimental-jit`, `--experimental-jit-off`, `--experimental-interpreter`. In the C code, `_Py_JIT` is defined as before when the JIT is enabled; the new variable `_Py_TIER2` is defined when the JIT *or* the interpreter is enabled. It is actually a bitmask: 1: JIT; 2: default-off; 4: interpreter.
* gh-118422: Fix run_fileexflags() test (#118429)Victor Stinner2024-04-301-7/+6
| | | | | Don't test the undefined behavior of fileno() on a closed file, but use fstat() as a reliable test if the file was closed or not.

| | | | | | Avoid detaching thread state when stopping the world. When re-attaching the thread state, the thread would attempt to resume the top-most critical section, which might now be held by a thread paused for our stop-the-world request.

* gh-117783: Immortalize objects that use deferred reference counting (#118112)Sam Gross2024-04-291-0/+22
| | | | | | | | | Deferred reference counting is not fully implemented yet. As a temporary measure, we immortalize objects that would use deferred reference counting to avoid multi-threaded scaling bottlenecks. This is only performed in the free-threaded build once the first non-main thread is started. Additionally, some tests, including refleak tests, suppress this behavior.
* gh-118285: Fix signatures of operator.{attrgetter,itemgetter,methodcaller} ↵Serhiy Storchaka2024-04-291-0/+15
| | | | | | | | | instances (GH-118316) * Allow to specify the signature of custom callable instances of extension type by the __text_signature__ attribute. * Specify signatures of operator.attrgetter, operator.itemgetter, and operator.methodcaller instances.

| | | | | | | | (GH-118230) The behavior of fileno() after fclose() is undefined, but it is the only practical way to check whether the file was closed. Only test this on the known platforms (Linux, Windows, macOS), where we already tested that it works.

* gh-117151: optimize BufferedWriter(), do not buffer writes that are the ↵morotti2024-04-231-2/+2
| | | | | | | | | buffer size (GH-118037) BufferedWriter() was buffering calls that are the exact same size as the buffer. it's a very common case to read/write in blocks of the exact buffer size. it's pointless to copy a full buffer, it's costing extra memory copy and the full buffer will have to be written in the next call anyway.

* gh-117845: Detect libedit hook function signature in configure (#117870)Joshua Root2024-04-171-2/+2
| | | | | | Older libedit versions (like Apple's) use a different type signature for rl_startup_hook and rl_pre_input_hook. Add a configure check to determine which signature is accepted by introducing the Py_RL_STARTUP_HOOK_TAKES_ARGS macro in pyconfig.h.
