* gh-103826: fix unused variable warning introduced in gh-102343 (#103825)sunmy20192023-04-251-2/+2

* gh-100227: Add a Granular Lock for _PyRuntime.imports.extensions.dict ↵Eric Snow2023-04-253-4/+16
| | | | | | (gh-103460) The lock is unnecessary as long as there's a GIL, but completely necessary with a per-interpreter GIL.
* gh-103636: add enums for days and months in calendar module (GH-103642)Prince Roshan2023-04-252-21/+40
| | | Convert day contants to a Day enum, and add a Month enum.
* gh-103718: Correctly set f-string buffers in all cases (GH-103815)Lysandros Nikolaou2023-04-251-8/+6
| | | | | | Turns out we always need to remember/restore fstring buffers in all of the stack of tokenizer modes, cause they might change to `TOK_REGULAR_MODE` and have newlines inside the braces (which is when we need to reallocate the buffer and restore the fstring ones).
* gh-82814: fix shutil access error on WSL (#103790)Allan Lago2023-04-252-1/+4
| | | | | | | gh-82814: Adds `errno.EACCES` to the list of ignored errors on `_copyxattr`. EPERM and EACCES are different constants but in general should be treated the same. News entry authored by: Gregory P. Smith <greg@krypto.org>

| | | | | | | | | | | | | | | | This PR makes some minor linting adjustments to the Lib/test module caught by [ruff](https://github.com/charliermarsh/ruff). The adjustments are all related to the `F541 f-string without any placeholders` issue.

* gh-101659: Isolate "obmalloc" State to Each Interpreter (gh-101660)Eric Snow2023-04-2420-73/+322
| | | | | | | | | | | | | | This is strictly about moving the "obmalloc" runtime state from `_PyRuntimeState` to `PyInterpreterState`. Doing so improves isolation between interpreters, specifically most of the memory (incl. objects) allocated for each interpreter's use. This is important for a per-interpreter GIL, but such isolation is valuable even without it. FWIW, a per-interpreter obmalloc is the proverbial canary-in-the-coalmine when it comes to the isolation of objects between interpreters. Any object that leaks (unintentionally) to another interpreter is highly likely to cause a crash (on debug builds at least). That's a useful thing to know, relative to interpreter isolation.
* gh-103801: Tools/wasm linting and formatting (#103796)Daniel Versoza2023-04-243-3/+5

* gh-95795: Move types.next_version_tag to PyInterpreterState (gh-102343)Eric Snow2023-04-244-43/+94
| | | | | | Core static types will continue to use the global value. All other types will use the per-interpreter value. They all share the same range, where the global types use values < 2^16 and each interpreter uses values higher than that.
* gh-87729: add LOAD_SUPER_ATTR instruction for faster super() (#103497)Carl Meyer2023-04-2418-408/+783
| | | | | This speeds up `super()` (by around 85%, for a simple one-level `super().meth()` microbenchmark) by avoiding allocation of a new single-use `super()` object on each use.

* gh-100227: Only Use deepfreeze for the Main Interpreter (gh-103794)Eric Snow2023-04-243-34/+58
| | | | | | | Deep-frozen code objects are cannot be shared (currently) by interpreters, due to how adaptive specialization can modify the bytecodes. We work around this by only using the deep-frozen objects in the main interpreter. This does incur a performance penalty for subinterpreters, which we may be able to resolve later.

* gh-103323: Get the "Current" Thread State from a Thread-Local Variable ↵Eric Snow2023-04-245-18/+73
| | | | | | | | | | | (gh-103324) We replace _PyRuntime.tstate_current with a thread-local variable. As part of this change, we add a _Py_thread_local macro in pyport.h (only for the core runtime) to smooth out the compiler differences. The main motivation here is in support of a per-interpreter GIL, but this change also provides some performance improvement opportunities. Note that we do not provide a fallback to the thread-local, either falling back to the old tstate_current or to thread-specific storage (PyThread_tss_*()). If that proves problematic then we can circle back. I consider it unlikely, but will run the buildbots to double-check. Also note that this does not change any of the code related to the GILState API, where it uses a thread state stored in thread-specific storage. I suspect we can combine that with _Py_tss_tstate (from here). However, that can be addressed separately and is not urgent (nor critical). (While this change was mostly done independently, I did take some inspiration from earlier (~2020) work by @markshannon (main...markshannon:threadstate_in_tls) and @vstinner (#23976).)
