* GH-103805: Lib test f541 linting issue fix (#103812)Rodolfo M. Pereira2023-04-2414-90/+90
| | | | | | | | | | | | | | | | 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-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).)

| | | | | | | | | | | | | | bpo-37222: Fix for CacheFTPHandler in urllib A call to FTP.ntransfercmd must be followed by FTP.voidresp to clear the "end transfer" message. Without this, the client and server get out of sync, which will result in an error if the FTP instance is reused to open a second URL. This scenario occurs for even the most basic usage of CacheFTPHandler. Reverts the patch merged as a resolution to bpo-16270 and adds a test case for the CacheFTPHandler in test_urllib2net.py.
