Scheduled weekly dependency update for week 28

[pyup-bot]

Update twisted[conch,tls] from 18.4.0 to 18.7.0.

Changelog

18.7.0

===========================

Features
--------

- Cancelling a Deferred returned by twisted.internet.defer.inlineCallbacks now cancels the Deferred it is waiting on. (4632)
- twisted.application.internet.ClientService now accepts a function to initialize or validate a connection before it is returned by the whenConnected method as the prepareConnection argument. (8375)
- Traceback generated for twisted.internet.defer.inlineCallbacks now includes the full stack of inlineCallbacks generators between catcher and raiser (before it only contained raiser's stack). (9176)
- Add optional cwd argument to twisted.runner.procmon.ProcMon.addProcess (9287)
- twisted.python.failure.Failure tracebacks generated by coroutines scheduled with twisted.internet.defer.ensureDeferred - i.e. any Deferred-awaiting coroutine - now contain fewer extraneous frames from the trampoline implementation, and correctly indicate the source of exceptions raised in other call stacks - i.e. the function that raised the exception.  In other words: if you 'await' a function that raises an exception, you'll be able to see where the error came from. (9459)


Bugfixes
--------

- On UNIX-like platforms, Twisted attempts to recover from EMFILE when accepting connections on TCP and UNIX ports by shedding incoming clients. (5368)
- The documentation of IReactorTime.getDelayedCalls() has been corrected to indicate that the method returns a list, not a tuple. (9418)
- "python -m twisted web --help" now refers to "--listen" instead of the non-existing "--http" (9434)
- twisted.python.htmlizer.TokenPrinter now explicitly works on bytestrings. (9442)
- twisted.enterprise.adbapi.ConnectionPool.runWithConnection and runInteraction now use the reactor that is passed to ConnectionPool's constructor. (9467)


Improved Documentation
----------------------

- The Twisted Coding Standard now contains examples of how to mark up a feature as added in the next Twisted release. (9460)


Deprecations and Removals
-------------------------

- Deprecate direct introspection of ProcMon's processes: processes should not be directly accessed or pickled. (9287)
- twisted.internet.address.IPv4Address._bwHack and twisted.internet.address.UNIXAddress._bwHack, as well as the parameters to the constructors, deprecated since Twisted 11.0, have been removed. (9450)


Misc
----

- 7495, 9399, 9406, 9411, 9425, 9439, 9449, 9450, 9452


Conch
-----

Features
~~~~~~~~

- twisted.conch.ssh.transport.SSHTransportBase now includes Twisted's version in the software version string it sends to the server, allowing servers to apply compatibility workarounds for bugs in particular client versions. (9424)


Bugfixes
~~~~~~~~

- If the command run by twisted.conch.endpoints.SSHCommandClientEndpoint exits because of a delivered signal, the client protocol's connectionLost is now called with a ProcessTerminated exception instead of a ConnectionDone exception. (9412)
- twisted.conch.ssh.transport.SSHTransportBase now correctly handles MSG_DEBUG with a false alwaysDisplay field on Python 2 (broken since 8.0.0). (9422)
- twisted.conch.manhole.lastColorizedLine now does not throw a UnicodeDecodeError on non-ASCII input. (9442)


Web
---

Features
~~~~~~~~

- Added support for SameSite cookies in ``http.Request.addCookie``. (9387)


Bugfixes
~~~~~~~~

- twisted.web.server.GzipEncoderFactory would sometimes fail to gzip requests if the Accept-Encoding header contained whitespace between the comma-separated acceptable encodings. It now trims whitespace before checking if gzip is an acceptable encoding. (9086)
- twisted.web.static.File renders directory listings on Python 2, including those with text paths. (9438)
- twisted.python.http.Request now correcly parses multipart bodies on Python 3.7. (9448)
- twisted.web.http.combinedLogFormatter (used by t.w.http.Server and t.w.server.Site) no longer produces DeprecationWarning about Request.getClientIP. (9470)
