* gh-115999: Add free-threaded specialization for `UNPACK_SEQUENCE` (#126600)Kirill Podoprigora2024-11-227-30/+103
| | | | | | | | | | | Add free-threaded specialization for `UNPACK_SEQUENCE` opcode. `UNPACK_SEQUENCE_TUPLE/UNPACK_SEQUENCE_TWO_TUPLE` are already thread safe since tuples are immutable. `UNPACK_SEQUENCE_LIST` is not thread safe because of nature of lists (there is nothing preventing another thread from adding items to or removing them the list while the instruction is executing). To achieve thread safety we add a critical section to the implementation of `UNPACK_SEQUENCE_LIST`, especially around the parts where we check the size of the list and push items onto the stack. --------- Co-authored-by: Matt Page <mpage@meta.com> Co-authored-by: mpage <mpage@cs.stanford.edu>

| | | | | | | | | * Name without a PATHEXT extension is only searched if the mode does not include X_OK. * Support multi-component PATHEXT extensions (e.g. ".foo.bar"). * Support files without extensions in PATHEXT contains dot-only extension (".", "..", etc). * Support PATHEXT extensions that end with a dot (e.g. ".foo.").

* gh-86463: Fix default prog in subparsers if usage is used in the main parser ↵Serhiy Storchaka2024-11-224-5/+60
| | | | | | | | | | (GH-125891) The usage parameter of argparse.ArgumentParser no longer affects the default value of the prog parameter in subparsers. Previously the full custom usage of the main parser was used as the prog prefix in subparsers.
* gh-127076: Ignore memory mmap in FileIO testing (#127088)Cody Maloney2024-11-223-7/+37
| | | | | | | | | | | | | `mmap`, `munmap`, and `mprotect` are used by CPython for memory management, which may occur in the middle of the FileIO tests. The system calls can also be used with files, so `strace` includes them in its `%file` and `%desc` filters. Filter out the `mmap` system calls related to memory allocation for the file tests. Currently FileIO doesn't do `mmap` at all, so didn't add code to track from `mmap` through `munmap` since it wouldn't be used. For now if an `mmap` on a fd happens, the call will be included (which may cause test to fail), and at that time support for tracking the address throug `munmap` could be added.
* gh-126700: pygettext: Support more gettext functions (GH-126912)Tomas R.2024-11-227-90/+260

* gh-127065: Make `methodcaller` thread-safe in free threading build (#127109)Sam Gross2024-11-222-0/+11
| | | | | | | The `methodcaller` C vectorcall implementation uses an arguments array that is shared across calls. The first argument is modified on every invocation. This isn't thread-safe in the free threading build. I think it's also not safe in general, but for now just disable it in the free threading build.

| | | | | Discard any 'localhost' authority from the beginning of a `file:` URI. As a result, file URIs like `//localhost/etc/hosts` are correctly decoded as `/etc/hosts`.

* gh-115999: Specialize `LOAD_GLOBAL` in free-threaded builds (#126607)mpage2024-11-2111-69/+222
| | | | | | | | | | | | | | Enable specialization of LOAD_GLOBAL in free-threaded builds. Thread-safety of specialization in free-threaded builds is provided by the following: A critical section is held on both the globals and builtins objects during specialization. This ensures we get an atomic view of both builtins and globals during specialization. Generation of new keys versions is made atomic in free-threaded builds. Existing helpers are used to atomically modify the opcode. Thread-safety of specialized instructions in free-threaded builds is provided by the following: Relaxed atomics are used when loading and storing dict keys versions. This avoids potential data races as the dict keys versions are read without holding the dictionary's per-object lock in version guards. Dicts keys objects are passed from keys version guards to the downstream uops. This ensures that we are loading from the correct offset in the keys object. Once a unicode key has been stored in a keys object for a combined dictionary in free-threaded builds, the offset that it is stored in will never be reused for a different key. Once the version guard passes, we know that we are reading from the correct offset. The dictionary read fast-path is used to read values from the dictionary once we know the correct offset.
* gh-114940: Add _Py_FOR_EACH_TSTATE_UNLOCKED(), and Friends (gh-127077)Eric Snow2024-11-219-87/+79
| | | This is a precursor to the actual fix for gh-114940, where we will change these macros to use the new lock. This change is almost entirely mechanical; the exceptions are the loops in codeobject.c and ceval.c, which now hold the "head" lock. Note that almost all of the uses of _Py_FOR_EACH_TSTATE_UNLOCKED() here will change to _Py_FOR_EACH_TSTATE_BEGIN() once we add the new per-interpreter lock.

* gh-127076: Disable strace tests under LD_PRELOAD (#127086)Cody Maloney2024-11-212-0/+9
| | | | | | | | Distribution tooling (ex. sandbox on Gentoo and fakeroot on Debian) uses LD_PRELOAD to intercept system calls and potentially modify them when building. These tools can change the set of system calls, so disable system call testing under these cases. Co-authored-by: Michał Górny <mgorny@gentoo.org>

* gh-97514: Authenticate the forkserver control socket. (GH-99309)Gregory P. Smith2024-11-206-16/+141
| | | | | | | | | | | | | | | | | | | This adds authentication to the forkserver control socket. In the past only filesystem permissions protected this socket from code injection into the forkserver process by limiting access to the same UID, which didn't exist when Linux abstract namespace sockets were used (see issue) meaning that any process in the same system network namespace could inject code. We've since stopped using abstract namespace sockets by default, but protecting our control sockets regardless of type is a good idea. This reuses the HMAC based shared key auth already used by `multiprocessing.connection` sockets for other purposes. Doing this is useful so that filesystem permissions are not relied upon and trust isn't implied by default between all processes running as the same UID with access to the unix socket. ### pyperformance benchmarks No significant changes. Including `concurrent_imap` which exercises `multiprocessing.Pool.imap` in that suite. ### Microbenchmarks This does _slightly_ slow down forkserver use. How much so appears to depend on the platform. Modern platforms and simple platforms are less impacted. This PR adds additional IPC round trips to the control socket to tell forkserver to spawn a new process. Systems with potentially high latency IPC are naturally impacted more. Typically a 1-4% slowdown on a very targeted process creation microbenchmark, with a worst case overloaded system slowdown of 20%. No evidence that these slowdowns appear in practical sense. See the PR for details.
