====================
Features
--------
- Make worker threads created by :class:`gevent.threadpool.ThreadPool` install
the :func:`threading.setprofile` and :func:`threading.settrace` hooks
while tasks are running. This provides visibility to profiling and
tracing tools like yappi.
Reported by Suhail Muhammed.
See :issue:`1678`.
- Drop support for Python 3.5.
Bugfixes
--------
- Incorrectly passing an exception *instance* instead of an exception
*type* to `gevent.Greenlet.kill` or `gevent.killall` no longer prints
an exception to stderr.
See :issue:`1663`.
- Make destroying a hub try harder to more forcibly stop loop processing
when there are outstanding callbacks or IO operations scheduled.
Thanks to Josh Snyder (:issue:`1686`) and Jan-Philip Gehrcke
(:issue:`1669`).
See :issue:`1686`.
- Improve the ability to use monkey-patched locks, and
`gevent.lock.BoundedSemaphore`, across threads, especially when the
various threads might not have a gevent hub or any other active
greenlets. In particular, this handles some cases that previously
raised ``LoopExit`` or would hang. Note that this may not be reliable
on PyPy on Windows; such an environment is not currently recommended.
The semaphore tries to avoid creating a hub if it seems unnecessary,
automatically creating one in the single-threaded case when it would
block, but not in the multi-threaded case. While the differences
should be correctly detected, it's possible there are corner cases
where they might not be.
If your application appears to hang acquiring semaphores, but adding a
call to ``gevent.get_hub()`` in the thread attempting to acquire the
semaphore before doing so fixes it, please file an issue.
See :issue:`1698`.
- Make error reporting when a greenlet suffers a `RecursionError` more
reliable.
Reported by Dan Milon.
See :issue:`1704`.
- gevent.pywsgi: Avoid printing an extra traceback ("TypeError: not
enough arguments for format string") to standard error on certain
invalid client requests.
Reported by Steven Grimm.
See :issue:`1708`.
- Add support for PyPy2 7.3.3.
See :issue:`1709`.
- Python 2: Make ``gevent.subprocess.Popen.stdin`` objects have a
``write`` method that guarantees to write the entire argument in
binary, unbuffered mode. This may require multiple trips around the
event loop, but more closely matches the behaviour of the Python 2
standard library (and gevent prior to 1.5). The number of bytes
written is still returned (instead of ``None``).
See :issue:`1711`.
- Make `gevent.pywsgi` stop trying to enforce the rules for reading chunked input or
``Content-Length`` terminated input when the connection is being
upgraded, for example to a websocket connection. Likewise, if the
protocol was switched by returning a ``101`` status, stop trying to
automatically chunk the responses.
Reported by Kavindu Santhusa.
See :issue:`1712`.
- Remove the ``__dict__`` attribute from `gevent.socket.socket` objects. The
standard library socket do not have a ``__dict__``.
Noticed by Carson Ip.
As part of this refactoring, share more common socket code between Python 2
and Python 3.
See :issue:`1724`.
