[3.6] bpo-33622: Fix issues with handling errors in the GC. (GH-7078) (GH-7095)

2018-05-24T13:05:38+00:00

* Fixed a leak when the GC fails to add an object with __del__ into
  the gc.garbage list.
* PyGC_Collect() can now be called when an exception is set and
  preserves it.
* Fixed an undefined behavior with comparing a dead pointer with NULL.
(cherry picked from commit 301e3cc8a5bc68c5347ab6ac6f83428000d31ab2)

DTrace support: function calls, GC activity, line execution

2016-09-10T00:37:37+00:00

Tested on macOS 10.11 dtrace, Ubuntu 16.04 SystemTap, and libbcc.

Largely based by an initial patch by Jesús Cea Avión, with some
influence from Dave Malcolm's SystemTap patch and Nikhil Benesch's
unification patch.

Things deliberately left out for simplicity:
- ustack helpers, I have no way of testing them at this point since
they are Solaris-specific
- PyFrameObject * in function__entry/function__return, this is
SystemTap-specific
- SPARC support
- dynamic tracing
- sys module dtrace facility introspection

All of those might be added later.

Issue #22043: time.monotonic() is now always available

2014-09-02T21:18:25+00:00

threading.Lock.acquire(), threading.RLock.acquire() and socket operations now
use a monotonic clock, instead of the system clock, when a timeout is used.
