py-httpx: updated to 0.21.0

0.21.0 (15th November, 2021)

The 0.21.0 release integrates against a newly redesigned httpcore backend.

Both packages ought to automatically update to the required versions, but if you are seeing any issues, you should ensure that you have httpx==0.21.* and httpcore==0.14.* installed.

Added

The command-line client will now display connection information when -v/--verbose is used.
The command-line client will now display server certificate information when -v/--verbose is used.
The command-line client is now able to properly detect if the outgoing request should be formatted as HTTP/1.1 or HTTP/2, based on the result of the HTTP/2 negotiation.

Removed

Curio support is no longer currently included. Please get in touch if you require this, so that we can assess priorities.

(adam)

py-httpcore: updated to 0.14.1

0.14.1 (November 12th, 2021)

max_connections becomes optional.
certifi is now included in the install dependancies.
h2 is now strictly optional.

0.14.0 (November 11th, 2021)

The 0.14 release is a complete reworking of httpcore, comprehensively addressing some underlying issues in the connection pooling, as well as substantially redesigning the API to be more user friendly.

Some of the lower-level API design also makes the components more easily testable in isolation, and the package now has 100% test coverage.

There's some other neat bits in there too, such as the "trace" extension, which gives a hook into inspecting the internal events that occur during the request/response cycle. This extension is needed for the HTTPX cli, in order to...

Log the point at which the connection is established, and the IP/port on which it is made.
Determine if the outgoing request should log as HTTP/1.1 or HTTP/2, rather than having to assume it's HTTP/2 if the --http2 flag was passed. (Which may not actually be true.)
Log SSL version info / certificate info.
Note that curio support is not currently available in 0.14.0. If you're using httpcore with curio please get in touch, so we can assess if we ought to prioritize it as a feature or not.

pkg_install: Switch to posix_spawn() on newer macOS.

vfork() no longer works on Monterey and causes serious intermittent issues
when upgrading pkg_install.  Forking the INSTALL and DEINSTALL scripts can
sometimes fail, due to the underlying pkg_add/pkg_delete binaries having
been changed or removed, leaving the system broken with no package tools.

The manual page suggests using posix_spawn() instead and that appears to
work correctly.  The code has been laid out so that it's easy enough to
switch other platforms to posix_spawn() too if required, or for improved
performance, and has been verified to work successfully on SmartOS.

Bump pkg_install version to 20211115.

mkvtoolnix: updated to 63.0.0

Version 63.0.0 "Everything" 2021-11-14

New features and enhancements

* mkvmerge: AC-3 parser: E-AC-3 with BSID values > 10 and ≤ 15 are recognized
  now, too.
* mkvmerge: when using language codes for track selection (e.g. `-a und,en`)
  all tracks that do not have a language property (due to their container not
  providing one, e.g. AVIs) will be treated as if they did have one set to
  `und` ("undetermined") as that is the language the track will have in the
  Matroska file anyway. Before this change it wasn't possible to match such
  tracks via language codes.
* MKVToolNix GUI: only on Windows: when compiled with Qt ≥ 5.14 and < 6 (which
  is the case for the officially provided binaries) fractional screen scaling
  will be enabled. This means that the GUI will be scaled appropriately if
  Windows is set to 125%, 150% or 175% instead of being too small or too
  large.
* MKVToolNix GUI: the spinner in the bottom right corner will now be hidden
  when no jobs are currently running.
* MKVToolNix GUI: header editor: a new column has been added to the tree view
  showing the status of the "track enabled" flag. The information is also
  shown on the track overview page on the right.
* MKVToolNix GUI: header editor: users can now reorder tracks by dragging &
  dropping.

Bug fixes

* mkvmerge: AVI reader: fixed reading AVI files that contain `vprp` video
  properties header chunks; reading aborted too early.

exim exim-html: updated to 4.95

Version 4.95
------------

1. The fast-ramp two phase queue run support, previously experimental, is
    now supported by default.

2. The native SRS support, previously experimental, is now supported. It is
    not built unless specified in the Local/Makefile.

3. TLS resumption support, previously experimental, is now supported and
    included in default builds.

4. Single-key LMDB lookups, previously experimental, are now supported.
    The support is not built unless specified in the Local/Makefile.

5. Option "message_linelength_limit" on the smtp transport to enforce (by
    default) the RFC 998 character limit.

6. An option to ignore the cache on a lookup.

7. Quota checking during reception (i.e. at SMTP time) for appendfile-
    transport-managed quotas.

8. Sqlite lookups accept a "file=<path>" option to specify a per-operation
    db file, replacing the previous prefix to the SQL string (which had
    issues when the SQL used tainted values).

9. Lsearch lookups accept a "ret=full" option, to return both the portion
    of the line matching the key, and the remainder.

10. A command-line option to have a daemon not create a notifier socket.

11. Faster TLS startup.  When various configuration options contain no
    expandable elements, the information can be preloaded and cached rather
    than the previous behaviour of always loading at startup time for every
    connection.  This helps particularly for the CA bundle.

12. Proxy Protocol Timeout is configurable via "proxy_protocol_timeout"
    main config option.

13. Option "smtp_accept_max_per_connection" is now expanded.

14. Log selector "queue_size_exclusive", enabled by default, to exclude the
    time taken for reception from QT log elements.

15. Main option "smtp_backlog_monitor", to set a level above which listen
    socket backlogs are logged.

16. Main option "hosts_require_helo", requiring HELO or EHLO before MAIL.

17. A main config option "allow_insecure_tainted_data" allows to turn

18. TLS ALPN handling.  By default, refuse TLS connections that try to specify
    a non-smtp (eg. http) use.  Options for customising.

19. Support for MacOS (darwin) has been dropped.

nginx-devel: updated to 1.21.4

Changes with nginx 1.21.4

*) Change: support for NPN instead of ALPN to establish HTTP/2
  connections has been removed.

*) Change: now nginx rejects SSL connections if ALPN is used by the
  client, but no supported protocols can be negotiated.

*) Change: the default value of the "sendfile_max_chunk" directive was
  changed to 2 megabytes.

*) Feature: the "proxy_half_close" directive in the stream module.

*) Feature: the "ssl_alpn" directive in the stream module.

*) Feature: the $ssl_alpn_protocol variable.

*) Feature: support for SSL_sendfile() when using OpenSSL 3.0.

*) Feature: the "mp4_start_key_frame" directive in the
  ngx_http_mp4_module.
  Thanks to Tracey Jaquith.

*) Bugfix: in the $content_length variable when using chunked transfer
  encoding.

*) Bugfix: after receiving a response with incorrect length from a
  proxied backend nginx might nevertheless cache the connection.
  Thanks to Awdhesh Mathpal.

*) Bugfix: invalid headers from backends were logged at the "info" level
  instead of "error"; the bug had appeared in 1.21.1.

*) Bugfix: requests might hang when using HTTP/2 and the "aio_write"
  directive.

py-zmq: updated to 22.3.0

22.3.0
======

Fixes:

- Fix `strlcpy` compilation issues on alpine, freebsd.
  Adds new build-time dependency on `packaging`.
- In event-loop integration: warn instead of raise when triggering callback on a socket whose context has been closed.
- Bundled libzmq in wheels backport a patch to avoid crashes
  due to inappropriate closing of libsodium's random generator
  when using CurveZMQ.

Changes:

- New ResourceWarnings when contexts and sockets are closed by garbage collection,
  which can be a source of hangs and leaks (matches open files)

22.2.1
======

Fix bundling of wepoll on Windows.

22.2.0
======

New features:

- IPC support on Windows:
  where available (64bit Windows wheels and bundled libzmq when compiling from source, via wepoll),
  IPC should work on appropriate Windows versions.
- Nicer reprs of contexts and sockets
- Memory allocated by `recv(copy=False)` is no longer read-only
- asyncio: Always reference current loop instead of attaching to the current loop at instantiation time.
  This fixes e.g. contexts and/or sockets instantiated prior to a call to `asyncio.run`.
- ssh: `$PYZMQ_PARAMIKO_HOST_KEY_POLICY` can be used to set the missing host key policy,
  e.g. `AutoAdd`.

Fixes:

- Fix memory corruption in gevent integration
- Fix `memoryview(zmq.Frame)` with cffi backend
- Fix threadsafety issue when closing sockets

Changes:

- pypy Windows wheels are 64b-only, following an update in cibuildwheel 2.0
- deprecate `zmq.utils.jsonapi` and remove support for non-stdlib json implementations in `send/recv_json`.
  Custom serialization methods should be used instead.

22.1.0
======

New features:

- asyncio: experimental support for Proactor eventloop if tornado 6.1 is available
  by running a selector in a background thread.

Fixes:

- Windows: fix type of `socket.FD` option in win-amd64
- asyncio: Cancel timers when using HWM with async Sockets

Other changes:

- Windows: update bundled libzmq dll URLs for Windows.
  Windows wheels no longer include concrt140.dll.
- adopt pre-commit for formatting, linting

22.0.3
======

- Fix fork-safety bug in garbage collection thread (regression in 20.0)
  when using subprocesses.
- Start uploading universal wheels for ARM Macs.

22.0.2
======

- Add workaround for bug in DLL loading for Windows wheels with conda Python >= 3.8

22.0.1
======

- Fix type of ``Frame.bytes`` for non-copying recvs with CFFI backend (regression in 21.0)
- Add manylinux wheels for pypy

22.0.0
======

This is a major release due to changes in wheels and building on Windows.
Code changes from 21.0 are minimal.

- Some typing fixes
- Bump bundled libzmq to 4.3.4
- Strip unused symbols in manylinux wheels, resulting in dramatically smaller binaries.
  This matches behavior in v20 and earlier.
- Windows CPython wheels bundle public libzmq binary builds,
  instead of building libzmq as a Python Extension.
  This means they include libsodium for the first time.
- Our own implementation of bundling libzmq into pyzmq on Windows is removed,
  instead relying on delvewheel (or installations putting dlls on %PATH%) to bundle dependency dlls.
- The (new in 21.0) Windows wheels for PyPy likely require the Windows vcredist package.
  This may have always been the case, but the delvewheel approach doesn't seem to work.
- Windows + PyPy is now the only remaining case where a wheel has libzmq built as an Extension.
  All other builds ship libzmq built using its own tooling,
  which should result in better, more stable builds.

21.0.2
======

- Fix wheels on macOS older than 10.15 (sets MACOSX_DEPLOYMENT_TARGET to 10.9, matching wheel ABI tag).

21.0.1
======

pyzmq-21.0.1 only changes CI configuration for Windows wheels (built with VS2017 instead of VS2019),
fixing compatibility with some older Windows on all Pythons
and removing requirement of VC++ redistributable package on latest Windows and Python < 3.8.

There still appears to be a compatibility issue with Windows 7 that will be fixed ASAP.
Until then, you can pin ``pip install pyzmq<21``.

There are no changes from 21.0.0 for other platforms.

21.0
====

pyzmq 21 is a major version bump because of dropped support for old Pythons and some changes in packaging.
CPython users should not face major compatibility issues if installation works at all :)
PyPy users may see issues with the new implementation of send/recv.
If you do, please report them!

The big changes are:

- drop support for Python 3.5. Python >= 3.6 is required
- mypy type stubs, which should improve static analysis of pyzmq,
  especially for dynamically defined attributes such as zmq constants.
  These are new! Let us know if you find any issues.
- support for zero-copy and sending bufferables with cffi backend.
  This is experimental! Please report issues.
- More wheels!
    - linux-aarch64 on Python 3.7-3.9
    - wheels for pypy36, 37 on Linux and Windows (previously just mac)

We've totally redone the wheel-building setup, so let us know if you start seeing instalation issues!

Packaging updates:

- Require Python >= 3.6, required for good type annotation support
- Wheels for macOS no longer build libzmq as a Python Extension,
  instead 'real' libzmq is built and linked to libsodium,
  bundled with delocate.
  This matches the longstanding behavior of Linux wheels,
  and should result in better performance.
- Add manylinux wheels for linux-aarch64. These bundle an older version of libzmq than the rest.
- Build wheels for python3.8, 3.9 with manylinux2010 instead of manylinux1.
  Wheels for older Pythons will still be built on manylinux1.
- rework cffi backend in setup.py
- All wheels are built on GitHub Actions (most with cibuildwheel) instead of Min's laptop (finally!).

New features:

- zero-copy support in CFFI backend (``send(copy=False)`` now does something).
- Support sending any buffer-interface-providing objects in CFFI backend.

Bugs fixed:

- Errors during teardown of asyncio Sockets
- Missing MSVCP140.dll in Python 3.9 wheels on Windows,
  causing vcruntime-redist package to be required to use the Python 3.9 wheels for pyzmq 20.0

20.0
====

20.0 is a major version bump because of dropped support for old Pythons and some changes in packaging,
but there are only small changes for users with relatively recent versions of Python.

Packaging updates:

- Update bundled libzmq to 4.3.3
- Drop support for Python < 3.5 (all versions of Python < 3.6 are EOL at time of release)
- Require setuptools to build from source
- Require Cython 0.29 to build from version control (sdists still ship .c files, so will never need Cython)
- Respect $PKG_CONFIG env for finding libzmq when building from source

New features:

- :meth:`.Socket.bind` and :meth:`.Socket.connect` can now be used as context managers.

Fixes:

- Better error when libzmq is bundled and fails to be loaded.
- Hold GIL while calling ``zmq_curve_`` functions, which may fix apparent threadsafety issues.

Security advisories:

CVE-2020-15166: Denial-of-Service on CURVE/ZAP-protected servers by
unauthenticated clients.
If a raw TCP socket is opened and connected to an endpoint that is fully
configured with CURVE/ZAP, legitimate clients will not be able to exchange
any message. Handshakes complete successfully, and messages are delivered to
the library, but the server application never receives them.
For more information see the security advisory:
GHSA-25wp-cf8g-938m
Stack overflow on server running PUB/XPUB socket (CURVE disabled).
The PUB/XPUB subscription store (mtrie) is traversed using recursive
function calls. In the remove (unsubscription) case, the recursive calls are
NOT tail calls, so even with optimizations the stack grows linearly with the
length of a subscription topic. Topics are under the control of remote
clients - they can send a subscription to arbitrary length topics. An
attacker can thus cause a server to create an mtrie sufficiently large such
that, when unsubscribing, traversal will cause a stack overflow.
For more information see the security advisory:
GHSA-qq65-x72m-9wr8
Memory leak in PUB server induced by malicious client(s) without CURVE/ZAP.
Messages with metadata are never processed by PUB sockets, but the metadata
is kept referenced in the PUB object and never freed.
For more information see the security advisory:
GHSA-4p5v-h92w-6wxw
Memory leak in client induced by malicious server(s) without CURVE/ZAP.
When a pipe processes a delimiter and is already not in active state but
still has an unfinished message, the message is leaked.
For more information see the security advisory:
GHSA-wfr2-29gj-5w87
Heap overflow when receiving malformed ZMTP v1 packets (CURVE disabled).
By crafting a packet which is not valid ZMTP v2/v3, and which has two
messages larger than 8192 bytes, the decoder can be tricked into changing
the recorded size of the 8192 bytes static buffer, which then gets overflown
by the next message. The content that gets written in the overflown memory
is entirely decided by the sender.
For more information see the security advisory:
GHSA-fc3w-qxf5-7hp6
Note for packagers: an external, self-contained sha1 library is now
included in the source tree under external/sha1/ - it is licensed
under BSD-3-Clause and thus it is fully compatible with libzmq's
license.
It is only used if WebSockets support is enabled, and if neither GnuTLS nor
NSS are available.

Note for packagers: an internal reimplementation of strlcpy is now included,
for wider platform compatibility.
libbsd can be used and is enabled by default if available instead of the
internal implementation, for better security maintenance in distros.

Note for packagers: ZeroMQConfig.cmake is now installed in the arch-dependent
subdirectory - eg: /usr/lib/x86_64-linux-gnu/cmake/

New DRAFT (see NEWS for 4.2.0) socket type:

ZMQ_CHANNEL is a thread-safe alternative to ZMQ_PAIR.
See doc/zmq_socket.txt for details.
New DRAFT (see NEWS for 4.2.0) socket option:

ZMQ_ONLY_FIRST_SUBSCRIBE will cause only the first part of a multipart
message to be processed as a subscribe/unsubscribe message, and the rest
will be forwarded as user data to the application.
ZMQ_RECONNECT_STOP will cause a connecting socket to stop trying to
reconnect in specific circumstances. See the manpage for details.
ZMQ_HELLO_MSG to set a message that will be automatically sent to a new
connection.
ZMQ_DISCONNECT_MSG to set a message that will be automatically received when
a peer disconnects.
See doc/zmq_setsockopt.txt and doc/zmq_getsockopt.txt for details.
New DRAFT (see NEWS for 4.2.0) zmq_ctx_get_ext/zmq_ctx_set_ext APIs were added
to allow enhancing the context options with variable data inputs.
See doc/zmq_ctx_get_ext.txt and doc/zmq_ctx_set_ext.txt for details.

New DRAFT (see NEWS for 4.2.0) transport options WS and WSS added for support
of WebSockets (and secure WebSockets via TLS) via the ZWS 2.0 protocol.
WSS requires the GnuTLS library for TLS support. ZMQ_WSS_ specific socket
options were added to support TLS.
WebSockets support is disabled by default if DRAFT APIs are disabled.

New DRAFT (see NEWS for 4.2.0) socket type, PEER, which is thread safe and a
related zmq_connect_peer function which atomically and thread-safely connects
and returns a routing-id.

New DRAFT (see NEWS for 4.2.0) zmq_msg_init_buffer API was added to allow
the construction of a message by copying from an existing buffer.

New DRAFT (see NEWS for 4.2.0) zmq_poller_size API was added to allow querying
the number of sockets/fds registered in a zmq_poller.

ZMTP 3.1 peers will receive subscribe/cancel on PUB/SUB via commands rather
than using the first byte of the payload.

zmq_z85_decode now checks that the input string's length is at least 5 characters
and always a multiple of 5 as per API specification.
