This matches what all versions of Python do and reverts https://github.com/gevent/gevent/commit/9b1bccffc11455112076189f35023291cf97a2a2 The bug that commit references was marked as "won't fix". This is part of an effort to adapt to changes in 3.7b2 that lead us to produce a different errno than the system does for `socket.create_connection(('localhost', ...))`

Interpret -1 to select.poll.poll as blocking, especially under libuv
-
Jason Madden authored
Why are we bothering to run cares on PyPy? It has several known-bad tests, and it sometimes crashes the interpreter. We don't recommend or support it now that we have dnspython.

Fix #1127 by interpreting -1 as None under libuv for select.poll.poll; should probably start having Timeout do that itself.

Add a GreenletTree for more organized, clearer output of greenlets

Jason Madden authored
It organizes things by the spawning greenlet, if possible. Example output:: ``` <greenlet.greenlet object at 0x10753a9b0> : Running: : File "/tmp/t.py", line 38, in <module> : print("\n".join(format_run_info())) : File "//src/gevent/util.py", line 99, in format_run_info : _format_greenlet_info(lines) : File "//src/gevent/util.py", line 132, in _format_greenlet_info : lines.extend(tree.format_lines(details=True)) : File "//src/gevent/util.py", line 265, in format_lines : for l in self._render(tree)] : File "/-main/src/gevent/util.py", line 310, in _render : self.__render_tb(tree, 'Running:', self.greenlet.gr_frame) : File "//src/gevent/util.py", line 281, in __render_tb : tb = ''.join(traceback.format_stack(frame)) : Greenlet Locals: : Local <type 'gevent._local.local'> at 0x10759cec0 : {'foo': 42} +--- <Greenlet "Greenlet-0" at 0x107405cb0: _run>; finished with value <Greenlet "Greenlet-4" at 0x10 : Parent: <Hub at 0x10753a550 select default pending=0 ref=0> : Spawned at: : File "/tmp/t.py", line 1, in <module> : from gevent.util import GreenletTree | +--- <Greenlet "Greenlet-4" at 0x10780b260: _run>; finished : Parent: <Hub at 0x10753a550 select default pending=0 ref=0> : Spawned at: : File "/tmp/t.py", line 1, in <module> : from gevent.util import GreenletTree : File "/tmp/t.py", line 12, in t2 : def t2(): +--- <Hub at 0x10753a550 select default pending=0 ref=0> : Parent: <greenlet.greenlet object at 0x10753a9b0> : Running: : File "/Users/jmadden/Projects/GithubSources/gevent-main/src/gevent/hub.py", line 673, in run : loop.run() +--- <Greenlet "Greenlet-1" at 0x10780b368: _run>; finished with value <Greenlet "Greenlet-5" at 0x10 : Parent: <Hub at 0x10753a550 select default pending=0 ref=0> : Spawned at: : File "/tmp/t.py", line 1, in <module> : from gevent.util import GreenletTree | +--- <Greenlet "Greenlet-5" at 0x10780b578: _run>; finished : Parent: <Hub at 0x10753a550 select default pending=0 ref=0> : Spawned at: : File "/tmp/t.py", line 1, in <module> : from gevent.util import GreenletTree : File "/tmp/t.py", line 12, in t2 : def t2(): +--- <Greenlet "Greenlet-2" at 0x10780b470: _run>; finished with value <Greenlet "Greenlet-6" at 0x10 : Parent: <Hub at 0x10753a550 select default pending=0 ref=0> : Spawned at: : File "/tmp/t.py", line 1, in <module> : from gevent.util import GreenletTree : Spawn Tree Locals : {'stl': 'STL'} | +--- <Greenlet "Greenlet-6" at 0x10780b680: _run>; finished with value <Greenlet "Greenlet-7" at 0x10 : Parent: <Hub at 0x10753a550 select default pending=0 ref=0> : Spawned at: : File "/tmp/t.py", line 1, in <module> : from gevent.util import GreenletTree : File "/tmp/t.py", line 21, in t3 : def t3(): | +--- <Greenlet "Greenlet-7" at 0x10780b788: _run>; finished : Parent: <Hub at 0x10753a550 select default pending=0 ref=0> : Spawned at: : File "/tmp/t.py", line 1, in <module> : from gevent.util import GreenletTree : File "/tmp/t.py", line 21, in t3 : def t3(): : File "/tmp/t.py", line 12, in t2 : def t2(): +--- <Greenlet "Greenlet-3" at 0x10780b890: _run>; finished with value [<gevent.util.GreenletTree obj Parent: <Hub at 0x10753a550 select default pending=0 ref=0> Spawned at: File "/tmp/t.py", line 1, in <module> from gevent.util import GreenletTree ```

Also let greenlets have a name. Some tweaks to the local implementation to speed it up by 3-4%.

Two ways: store tuples instead of _frame objects and use direct access to two of the attributes of the CPython frame objects.

none spawn; eventlet spawn kwarg; none spawn kwarg The eventlet, sleep, join and raw tests serve as controls, so we can see that there's up to ~10% variance between most runs anyway. CPython 3.6 shows the least variance so those 10-20% improvement numbers are probably fairly close. PyPy sadly gets *slower* with this change for reasons that are utterly unclear. Compared to 1.3a1 (last benchmark) we're still up to 2-3x slower. Creation of a raw greenlet shows 2.66us on CPython 3.6.4 vs the 3.65us I reported in #755.

Do this with some cython tricks and some caching of type attributes. Cython 0.28 compiles this code to be quite a bit faster than Cython 0.27 does (the below uses 0.28), but it's still a win on both. The type caching could potentially be a compatibility issue, but in practice I suspect it won't be.
