* [3.12] gh-101524: Only Use Public C-API in the _xxsubinterpreters Module ↵Miss Islington (bot)2023-07-271-0/+1
| | | | | | | | (gh-105258) (gh-107303) The _xxsubinterpreters module was meant to only use public API. Some internal C-API usage snuck in over the last few years (e.g. gh-28969). This fixes that.

* [3.12] Fix c-analyzer for GCC: ignore LANG env var (GH-106173) (#106178)Miss Islington (bot)2023-06-281-1/+7
| | | | | | | | | Fix c-analyzer for GCC: ignore LANG env var (GH-106173) The c-analyzer doesn't support GCC localized messages, so just unset the LANG environment variable. (cherry picked from commit 1f74b9e933d546a015e8497e3b8728357196acc8) Co-authored-by: Victor Stinner <vstinner@python.org>
* [3.12] gh-105699: Use a Thread-Local Variable for PKGCONTEXT (gh-105740) ↵Miss Islington (bot)2023-06-143-1/+9
| | | | | | | | (gh-105765) This fixes a race during import. The existing _PyRuntimeState.imports.pkgcontext is shared between interpreters, and occasionally this would cause a crash when multiple interpreters were importing extensions modules at the same time. To solve this we add a thread-local variable for the value. We also leave the existing state (and infrequent race) in place for platforms that do not support thread-local variables.

* [3.12] gh-104812: Run Pending Calls in any Thread (gh-104813) (gh-105752)Eric Snow2023-06-141-0/+1
| | | | For a while now, pending calls only run in the main thread (in the main interpreter). This PR changes things to allow any thread run a pending call, unless the pending call was explicitly added for the main thread to run. (cherry picked from commit 757b402)
* [3.12] gh-104614: Make Sure ob_type is Always Set Correctly by ↵Miss Islington (bot)2023-06-011-0/+2
| | | | | | | | | | PyType_Ready() (gh-105122) (gh-105211) When I added the relevant condition to type_ready_set_bases() in gh-103912, I had missed that the function also sets tp_base and ob_type (if necessary). That led to problems for third-party static types. We fix that here, by making those extra operations distinct and by adjusting the condition to be more specific.

* [3.12] gh-103142: Upgrade binary builds and CI to OpenSSL 1.1.1u (GH-105174) ↵Miss Islington (bot)2023-06-011-0/+1
| | | | | | | | | | | | | | | | | | | | (#105199) gh-103142: Upgrade binary builds and CI to OpenSSL 1.1.1u (GH-105174) Upgrade builds to OpenSSL 1.1.1u. This OpenSSL version addresses a pile if less-urgent CVEs since 1.1.1t. The Mac/BuildScript/build-installer.py was already updated. Also updates _ssl_data_111.h from OpenSSL 1.1.1u, _ssl_data_300.h from 3.0.9, and adds a new _ssl_data_31.h file from 3.1.1 along with the ssl.c code to use it. Manual edits to the _ssl_data_300.h file prevent it from removing any existing definitions in case those exist in some peoples builds and were important (avoiding regressions during backporting). backports of this prior to 3.12 will not include the openssl 3.1 header.

* GH-103082: Filter LINE events in VM, to simplify tool implementation. ↵Mark Shannon2023-05-121-1/+1
| | | | | | | | (GH-104387) When monitoring LINE events, instrument all instructions that can have a predecessor on a different line. Then check that the a new line has been hit in the instrumentation code. This brings the behavior closer to that of 3.11, simplifying implementation and porting of tools.
* gh-99108: Replace SHA3 implementation HACL* version (#103597)Jonathan Protzenko2023-05-081-7/+1
| | | | | | | | | | | Replaces our built-in SHA3 implementation with a verified one from the HACL* project. This implementation is used when OpenSSL does not provide SHA3 or is not present. 3.11 shiped with a very slow tiny sha3 implementation to get off of the <=3.10 reference implementation that wound up having serious bugs. This brings us back to a reasonably performing built-in implementation consistent with what we've just replaced our other guaranteed available standard hash algorithms with: code from the HACL* project. --------- Co-authored-by: Gregory P.

* gh-101659: Isolate "obmalloc" State to Each Interpreter (gh-101660)Eric Snow2023-04-241-0/+1
| | | | | | | | | | | | | | 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-102304: Move _Py_RefTotal to _PyRuntimeState (gh-102543)Eric Snow2023-03-201-1/+1
| | | | | | | The essentially eliminates the global variable, with the associated benefits. This is also a precursor to isolating this bit of state to PyInterpreterState.

* Exclude `ceval.c` from the C-analyzer tool (#102735)Alex Waygood2023-03-151-0/+5
| | | | | | | | | | The "check if generated files are up to date" CI check appears to be currently failing on all PRs (but not on pushes to main) See, for example: - https://github.com/python/cpython/pull/94468 - https://github.com/python/cpython/pull/94468 - https://github.com/python/cpython/pull/102731 This appears to be because the C-analyzer tool doesn't like the `#line` directives introduced in https://github.com/python/cpython/commit/70185de1abfe428049a5c43d58fcb656b46db96c. I'm advised by the message printed to the terminal in https://github.com/python/cpython/actions/runs/4428706945/jobs/7768216988#step:14:84 that this is the appropriate short-term fix!
* gh-81057: Add a CI Check for New Unsupported C Global Variables (gh-102506)Eric Snow2023-03-145-20/+81
| | | | | | | | | | | This will keep us from adding new unsupported (i.e. non-const) C global variables, which would break interpreter isolation. FYI, historically it is very uncommon for new global variables to get added. Furthermore, it is rare for new code to break the c-analyzer. So the check should almost always pass unnoticed. Note that I've removed test_check_c_globals. A test wasn't a great fit conceptually and was super slow on debug builds. A CI check is a better fit. This also resolves gh-100237. https://github.com/python/cpython/issues/81057
* gh-81057: Vendor a Subset of distutils for the c-analyzer Tool (gh-102505)Eric Snow2023-03-0915-0/+2301
| | | | | distutils was removed in November. However, the c-analyzer relies on it. To solve that here, we vendor the parts the tool needs so it can be run against 3.12+. (Also see gh-92584.) Note that we may end up removing this code later in favor of a solution in common with the peg_generator tool (which also relies on distutils). At the least, the copy here makes sure the c-analyzer tool works on 3.12+ in the meantime.
* gh-90110: Fix the c-analyzer Tool (#102483)Eric Snow2023-03-076-21/+70
| | | | | | | Some incompatible changes had gone in, and the "ignore" lists weren't properly undated. This change fixes that. It's necessary prior to enabling test_check_c_globals, which I hope to do soon. Note that this does include moving last_resort_memory_error to PyInterpreterState. https://github.com/python/cpython/issues/90110
