* gh-90536: Add support for the BOLT post-link binary optimizer (gh-95908)Kevin Modzelewski2022-08-187-1/+351
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Add support for the BOLT post-link binary optimizer Using [bolt](https://github.com/llvm/llvm-project/tree/main/bolt) provides a fairly large speedup without any code or functionality changes. It provides roughly a 1% speedup on pyperformance, and a 4% improvement on the Pyston web macrobenchmarks. It is gated behind an `--enable-bolt` configure arg because not all toolchains and environments are supported. It has been tested on a Linux x86_64 toolchain, using llvm-bolt built from the LLVM 14.0.6 sources (their binary distribution of this version did not include bolt). Compared to [a previous attempt](https://github.com/faster-cpython/ideas/issues/224), this commit uses bolt's preferred "instrumentation" approach, as well as adds some non-PIE flags which enable much better optimizations from bolt. The effects of this change are a bit more dependent on CPU microarchitecture than other changes, since it optimizes i-cache behavior which seems to be a bit more variable between architectures. The 1%/4% numbers were collected on an Intel Skylake CPU, and on an AMD Zen 3 CPU I got a slightly larger speedup (2%/4%), and on a c6i.xlarge EC2 instance I got a slightly lower speedup (1%/3%). The low speedup on pyperformance is not entirely unexpected, because BOLT improves i-cache behavior, and the benchmarks in the pyperformance suite are small and tend to fit in i-cache. This change uses the existing pgo profiling task (`python -m test --pgo`), though I was able to measure about a 1% macrobenchmark improvement by using the macrobenchmarks as the training task. I personally think that both the PGO and BOLT tasks should be updated to use macrobenchmarks, but for the sake of splitting up the work this PR uses the existing pgo task. * Simplify the build flags * Add a NEWS entry * Update Makefile.pre.in Co-authored-by: Dong-hee Na <donghee.na92@gmail.com> * Update configure.ac Co-authored-by: Dong-hee Na <donghee.na92@gmail.com> * Add myself to ACKS * Add docs * Other review comments * fix tab/space issue * Make it more clear that --enable-bolt is experimental * Add link to bolt's github page Co-authored-by: Dong-hee Na <donghee.na92@gmail.com>

* gh-95991: Add some infrastructure for testing Limited API in _testcapi ↵Petr Viktorin2022-08-177-23/+64
| | | | | | | | | | | | | (GH-95992) - Limited API needs to be enabled per source file - Some builds don't support Limited API, so Limited API tests must be skipped on those builds (currently this is `Py_TRACE_REFS`, but that may change.) - `Py_LIMITED_API` must be defined before `<Python.h>` is included. This puts the hoop-jumping in `testcapi/parts.h`, so individual test files can be relatively simple. (Currently that's only `vectorcall_limited.c`, imagine more.)

* GH-95704: Don't suppress errors from tasks when TG is cancelled (#95761)Guido van Rossum2022-08-173-28/+35
| | | | | | | | | | | | | When a task catches CancelledError and raises some other error, the other error should not silently be suppressed. Any scenario where a task crashes in cleanup upon cancellation will now result in an ExceptionGroup wrapping the crash(es) instead of propagating CancelledError and ignoring the side errors. NOTE: This represents a change in behavior (hence the need to change several tests). But it is only an edge case. Co-authored-by: Thomas Grainger <tagrain@gmail.com>

| | | | | | - On WASI `ENOTCAPABLE` is now mapped to `PermissionError`. - The `errno` modules exposes the new error number. - `getpath.py` now ignores `PermissionError` when it cannot open landmark files `pybuilddir.txt` and `pyenv.cfg`.
* gh-94823: Improve coverage in tokenizer.c:valid_utf8 (GH-94856)Michael Droettboom2022-08-161-0/+61
| | | | | | When loading a source file from disk, there is a separate UTF-8 validator distinct from the one in `unicode_decode_utf8`. This exercises that code path with the same set of invalid inputs as we use for testing the "other" UTF-8 decoder.

| | | | | | | | | | | | Automate WASM build with a new Python script. The script provides several build profiles with configure flags for Emscripten flavors and WASI. The script can detect and use Emscripten SDK and WASI SDK from default locations or env vars. ``configure`` now detects Node arguments and creates HOSTRUNNER arguments for Node 16. It also sets correct arguments for ``wasm64-emscripten``. Co-authored-by: Brett Cannon <brett@python.org>
