* bpo-44329: Refactor sqlite3 statement creation (GH-26566)Erlend Egeberg Aasland2021-06-081-43/+35
| | | | | Call SQLite API's first, and return early in case of error. At the end, allocate the object and initialise members. We now avoid unneeded alloc/dealloc's in case the statement creation fails.

* bpo-43693: Silence some compiler warnings. (gh-26588)Eric Snow2021-06-072-5/+2
| | | | | | | The plan is to eventually make PyCodeObject opaque in the public C-API, with the full struct moved to Include/internal/pycore_code.h. _PyLocalsPlusKinds and _PyLocalsPlusKind started off there but were needed on PyCodeObject, hence the duplication. This led to warnings with some compilers. (Apparently it does not trigger a warning on my install of GCC.) This change eliminates the superfluous typedef. https://bugs.python.org/issue43693

| | | | | | | (gh-26396) This moves logic out of the frame initialization code and into the compiler and eval loop. Doing so simplifies the runtime code and allows us to optimize it better. https://bugs.python.org/issue43693

* bpo-43693: Add new internal code objects fields: co_fastlocalnames and ↵Eric Snow2021-06-0321-5659/+5967
| | | | | | | | | | | | | | | | | co_fastlocalkinds. (gh-26388) A number of places in the code base (notably ceval.c and frameobject.c) rely on mapping variable names to indices in the frame "locals plus" array (AKA fast locals), and thus opargs. Currently the compiler indirectly encodes that information on the code object as the tuples co_varnames, co_cellvars, and co_freevars. At runtime the dependent code must calculate the proper mapping from those, which isn't ideal and impacts performance-sensitive sections. This is something we can easily address in the compiler instead. This change addresses the situation by replacing internal use of co_varnames, etc. with a single combined tuple of names in locals-plus order, along with a minimal array mapping each to its kind (local vs. cell vs. free). These two new PyCodeObject fields, co_fastlocalnames and co_fastllocalkinds, are not exposed to Python code for now, but co_varnames, etc. are still available with the same values as before (though computed lazily). Aside from the (mild) performance impact, there are a number of other benefits: * there's now a clear, direct relationship between locals-plus and variables * code that relies on the locals-plus-to-name mapping is simpler * marshaled code objects are smaller and serialize/de-serialize faster Also note that we can take this approach further by expanding the possible values in co_fastlocalkinds to include specific argument types (e.g. positional-only, kwargs). Doing so would allow further speed-ups in _PyEval_MakeFrameVector(), which is where args get unpacked into the locals-plus array. It would also allow us to shrink marshaled code objects even further. https://bugs.python.org/issue43693
* bpo-43921: Fix test_ssl.test_wrong_cert_tls13() on Windows (GH-26502)Victor Stinner2021-06-032-14/+9

| | | | | | | | | Try to harden connection close: - add tests that exercise stuff against a closed database - add wrapper for sqlite3_close_v2() - check connection on __enter__ - explicitly free pending statements before close() - sqlite3_close_v2() always returns SQLITE_OK
