* gh-111964: Implement stop-the-world pauses (gh-112471)Sam Gross2024-01-2310-29/+336
| | | | | | | | | | | | | | | | | The `--disable-gil` builds occasionally need to pause all but one thread. Some examples include: * Cyclic garbage collection, where this is often called a "stop the world event" * Before calling `fork()`, to ensure a consistent state for internal data structures * During interpreter shutdown, to ensure that daemon threads aren't accessing Python objects This adds the following functions to implement global and per-interpreter pauses: * `_PyEval_StopTheWorldAll()` and `_PyEval_StartTheWorldAll()` (for the global runtime) * `_PyEval_StopTheWorld()` and `_PyEval_StartTheWorld()` (per-interpreter) (The function names may change.) These functions are no-ops outside of the `--disable-gil` build.
* gh-112984: Fix link error on free-threaded Windows build (GH-114455)Sam Gross2024-01-231-0/+3
| | | | | | The test_peg_generator test tried to link the python313_d.lib library, which failed because the library is now named python313t_d.lib. The underlying problem is that the "compiler" attribute was not set when we call get_libraries() from distutils.

* gh-113317: Don't use global clinic instance in bad_argument() (#114330)Erlend E. Aasland2024-01-231-12/+11
| | | | | | | Make it possible for a converter to have multiple includes, by collecting them in a list on the converter instance. This implies converter includes are added during template generation, so we have to add them to the clinic instance at the end of the template generation instead of in the beginning.
* gh-89427: Provide the original prompt value for VIRTUAL_ENV_PROMPT (GH-106726)Jim Porter2024-01-236-10/+9
| | | | | | | | | | This improves the implementation in gh-106643. Previously, venv passed "(<prompt>) " to the activation scripts, but we want to provide the original value so that users can inspect it in the $VIRTUAL_ENV_PROMPT env var. Note: Lib/venv/scripts/common/Activate.ps1 surrounded the prompt value with parens a second time, so no change was necessary in that file.

* gh-112532: Improve mimalloc page visiting (#114133)Sam Gross2024-01-223-34/+134
| | | | | | | | | | | | | | | This adds support for visiting abandoned pages in mimalloc and improves the performance of the page visiting code. Abandoned pages contain memory blocks from threads that have exited. At some point, they may be later reclaimed by other threads. We still need to visit those pages in the free-threaded GC because they contain live objects. This also reduces the overhead of visiting mimalloc pages: * Special cases for full, empty, and pages containing only a single block. * Fix free_map to use one bit instead of one byte per block. * Use fast integer division by a constant algorithm when computing block offset from block size and index.

* gh-102512: Turn _DummyThread into _MainThread after os.fork() called from a ↵Serhiy Storchaka2024-01-223-9/+101
| | | | | | | | | | | | | | | | | foreign thread (GH-113261) Always set a _MainThread as a main thread after os.fork() is called from a thread started not by the threading module. A new _MainThread was already set as a new main thread after fork if threading.current_thread() was not called for a foreign thread before fork. Now, if it was called before fork, the implicitly created _DummyThread will be turned into _MainThread after fork. It fixes, in particularly, an incompatibility of _DummyThread with the threading shutdown logic which relies on the main thread having tstate_lock.

* gh-80931: Skip some socket tests while hunting for refleaks on macOS (#114057)Ronald Oussoren2024-01-213-1/+64
| | | | | Some socket tests related to sending file descriptors cause a file descriptor leak on macOS, all of them tests that send one or more descriptors than cannot be received on the read end. This appears to be a platform bug. This PR skips those tests when doing a refleak test run to avoid hiding other problems.
