* feat: Python 3.12+/3.13 compat + sub-interpreter wrapper
Hanzo fork of go-python/cpy3. See HANZO_CHANGES.md for full diff.
- Polyfill APIs removed in 3.12 (per-type ClearFreeList helpers) and
3.13 (PyEval_InitThreads, Py_SetPath/PythonHome/ProgramName,
PySys_SetArgv/AddWarnOption/AddXOption/SetPath,
Py_SetStandardStreamEncoding, PyEval_ThreadsInitialized) so existing
call sites compile against modern CPython. Polyfills route to the
PyConfig API where there's a meaningful replacement, return 0/no-op
otherwise.
- New PEP 684 SubInterpreter wrapper (subinterp.go) — recommended
primitive for tenant/per-worker isolation on 3.12+. Defaults follow
PEP 684 (own GIL, threads on, no daemon threads, refuse non-isolated
C extensions). Falls back to Py_NewInterpreter on 3.11 and older.
- Free-threading awareness (PEP 703) — IsGILDisabled() reports at
runtime whether the linked CPython was built with --disable-gil.
- pkg-config switched from "python3" to "python3-embed" so libpython
links cleanly on Linux distros that split the embed flags.
- Module path: github.com/go-python/cpy3 -> github.com/hanzoai/cpy3.
Go 1.21+. Package name (python3) unchanged.
- CI matrix: Python {3.11, 3.12, 3.13} x Go {1.21, 1.22} on Ubuntu.
License remains MIT. Original go-python team credited in HANZO_CHANGES.md
and every modified file's header.
* feat: JSON hot-path helper + 3.13t build script
- LoadSource + CallJSONFunctionByName: single-cgo-crossing helpers
for the common "JSON-in, JSON-out" extension embedding contract.
Roughly 2x faster than the long form via individual wrappers and
stack-safer under sustained load (macOS SIGBUS at ~400k iters of
the 9-call long form is mitigated by collapsing to 1 cgo call).
- ErrUnknownFunction: sentinel error for missing/non-callable
lookups so callers can errors.Is.
- scripts/build-python313t.sh: idempotent local build of CPython
3.13.x with --disable-gil. Writes a python3-embed.pc so callers
steer via PKG_CONFIG_PATH.
- HANZO_CHANGES.md + README updated.
- .gitignore: exclude python313t-build/ python313t-src/.
* ci: split test runs by Python global state
TestSubInterpreter_* and TestCallJSONFunctionByName_* / TestLoadSource_*
share global Py state with the data-type/error tests. Running them
in the same `go test` invocation can hang on darwin after the
data-type tests have already touched the main interpreter. Split
into two test steps so each starts from a fresh process.
* test: move json_hotpath tests in-package + share Py init
Move from package python3_test to package python3 so they share
Py_Initialize() state with subinterp_test.go. Each test pins its
own OS thread, calls Py_Initialize (idempotent), creates a fresh
sub-interp, and unpins on return. No PyEval_SaveThread in teardown
— the sub-interp's Close already released the calling thread's GIL.
This eliminates a SIGSEGV-on-second-test pattern caused by trying
to PyEval_SaveThread a state that's already been saved.
* docs: README example for the JSON hot path
Show LoadSource + CallJSONFunctionByName end-to-end with luxfi/log
for context. The helpers themselves take no logger dependency.
