Provide
Cython
/
nogil
API
with
goroutines
and
channels
.
Cython
API
is
not
only
faster
compared
to
Python
version
,
but
also
,
due
to
*
nogil
*
property
,
allows
to
build
concurrent
systems
without
limitations
imposed
by
Python
's GIL.
This work was motivated by wendelin.core__ v2, which, due to its design,
would deadlock if it tries to take the GIL in its pinner thread.
Implementation of Python-level goroutines and channels becomes tiny wrapper
around Cython/nogil API. This brings in ~5x speedup to Python-level `golang`
package along the way (`commit 1`__, 2__, 3__, 4__, 5__, 6__, 7__, 8__, 9__,
10__, 11__, 12__, 13__, 14__, 15__, 16__, 17__, 18__, 19__, 20__, 21__, 22__,
23__, 24__, 25__, 26__, 27__).

- Provide way to install Pygolang with extra requirements in the form of
`pygolang[<package>]`. For example `pygolang[x.perf.benchlib]` additionally
selects NumPy, `pygolang[pyx.build]` - everything needed by build system, and
`pygolang[all]` selects everything (commit__).
__ https://lab.nexedi.com/kirr/pygolang/commit/89a1061a
- Improve tests to exercise the implementation more thoroughly in many
places (`commit 1`__, 2__, 3__, 4__, 5__, 6__).

__ https://lab.nexedi.com/kirr/pygolang/commit/eb8a1fef
__ https://lab.nexedi.com/kirr/pygolang/commit/c6bb9eb3
- Fix deadlock in `sync.WorkGroup` tests (commit__).
__ https://lab.nexedi.com/kirr/pygolang/commit/b8b042c5
- Fix `@func(cls) def name` not to override `name` in calling context (commit__).
__ https://lab.nexedi.com/kirr/pygolang/commit/924a808c
- Fix `sync.WorkGroup` to propagate all exception types, not only those derived
from `Exception` (commit__).
__ https://lab.nexedi.com/kirr/pygolang/commit/79aab7df
- Replace `threading.Event` with `chan` in `sync.WorkGroup` implementation.
This removes reliance on outside semaphore+waitlist code and speeds up
`sync.WorkGroup` along the way (commit__).
__ https://lab.nexedi.com/kirr/pygolang/commit/78d85cdc
- Speedup `sync.WorkGroup` by not using `@func` at runtime (commit__).
__ https://lab.nexedi.com/kirr/pygolang/commit/94c6160b
- Add benchmarks for `chan`, `select`, `@func` and `defer` (commit__).
