This ensures that problems with entries added other modules, e.g.
mod_turn_external, are reported on startup. However, this depends on
load order and whether a `module:depends()` call comes before the
`module:add_item()` call. A followup commit will do something about
that.

The :info() method has been observed to return nothing ... sometimes.
Unclear what causes it. Perhaps the TLS connection was shut down or
hasn't fully settled?
The LuaSec code has code paths that return nothing or nil, error, so it
is best to guard against it.

This only differs from 'legacy_ssl' in name, at least on the server
side. For clients this is the one that uses SRV records.

X-Frame-Options was replaced by the Content-Security-Policy
'frame-ancestors' directive, but Internet Explorer does not support that
part of CSP.
Since it's just one line it doesn't hurt to keep until some future
spring cleaning event :)

Fixes "attempt to compare number with nil" because `session.version` has
been cleared by s2smanager.destroy_session.
This can happen with the server_epoll setting opportunistic_writes
enabled, which means that it can notice that the connection failed at
this point, after which it triggers the whole chain of events that leads
to session destruction and "cleaning" most of the session fields.

Some items like HTTP providers would be very verbose, others are tricky

Hosts have a metatable __tostring method that produces a nice
representation such as `VirtualHost "example.com"`, which even includes
the component module for internal components.

To show info about loaded modules. Inspired by the desire to know
whether a module was loaded from the core set or 3rd party.

Creates buckets up to the configured size limit or 1TB, whichever is

Nicer than the "unsupported stanza type" error we get otherwise.

Turns out you can seek past the end of the file without getting an
error.
Also rejects empty range instead of sending the whole file.

Originally added in 202b9951b037 but util.pubsub gained a better method
in 6c2c2fc4b8dd since then, which mod_pep uses since 9194431b6447 which
should have deleted this.
All these :create calls would have failed with a 'conflict' error, since
the nodes had already been created. This was never noticed because of
missing error handling.
Also note that this code did not restore node configuration.

Only a starting point is supported due to the way response:send_file()
sends everything it gets from the provided file handle but does not have
any way to specify how much to read.
This matches what Conversations appears to be doing.

The de-facto interpretation of this (undocumented) option is to indicate to
the client whether it is allowed to invite other users to the MUC.
This is differs from the existing option in our config form, which only
controls the behaviour of sending of invites in a members-only MUC (we always
allow invites in open rooms).
Conversations is one client known to use this disco#info item to determine
whether it may send invites.

stanza size limits
c2s/bosh/ws streams will default to 256KB, s2s and components to 512KB.
These values are aligned with ejabberd's default settings, which should reduce
issues related to inconsistent size limits between servers on the XMPP network.
The previous default (10MB) is excessive for any production server, and allows
significant memory usage by even unauthenticated sessions.

The metric subsystem of Prosody has had some shortcomings from
the perspective of the current state-of-the-art in metric
observability.
The OpenMetrics standard [0] is a formalization of the data
model (and serialization format) of the well-known and
widely-used Prometheus [1] software stack.
The previous stats subsystem of Prosody did not map well to that
format (see e.g. [2] and [3]); the key reason is that it was
trying to do too much math on its own ([2]) while lacking
first-class support for "families" of metrics ([3]) and
structured metric metadata (despite the `extra` argument to
metrics, there was no standard way of representing common things
like "tags" or "labels").
Even though OpenMetrics has grown from the Prometheus world of
monitoring, it maps well to other popular monitoring stacks
such as:
- InfluxDB (labels can be mapped to tags and fields as necessary)
- Carbon/Graphite (labels can be attached to the metric name with
dot-separation)
- StatsD (see graphite when assuming that graphite is used as
backend, which is the default)
The util.statsd module has been ported to use the OpenMetrics
model as a proof of concept. An implementation which exposes
the util.statistics backend data as Prometheus metrics is
ready for publishing in prosody-modules (most likely as
mod_openmetrics_prometheus to avoid breaking existing 0.11
deployments).
At the same time, the previous measure()-based API had one major
advantage: It is really simple and easy to use without requiring
lots of knowledge about OpenMetrics or similar concepts. For that
reason as well as compatibility with existing code, it is preserved
and may even be extended in the future.
However, code relying on the `stats-updated` event as well as
`get_stats` from `statsmanager` will break because the data
model has changed completely; in case of `stats-updated`, the
code will simply not run (as the event was renamed in order
to avoid conflicts); the `get_stats` function has been removed
completely (so it will cause a traceback when it is attempted
to be used).
Note that the measure_*_event methods have been removed from
the module API. I was unable to find any uses or documentation
and thus deemed they should not be ported. Re-implementation is
possible when necessary.

Can happen in case opportunistic_writes is enabled and the session got
destroyed while writing that tag.

Could happen with the 'opportunistic_writes' setting, since then the
stream opening is written directly to the socket, which can in turn
trigger session destruction if the socket somehow got closed just after
the other sent their stream header.
Error happens later when it tries to `hosts[session.host == nil].events`

This many returns deserve their own line.
`session["sasl_handler"]` style isn't used anywhere else.
|

|

We don't use the quoted table indexing style that often, it's not needed
here and it's enough to check for falsyness rather than `nil`.
