Many of these fall into a few categories:
- util.cache size, must be >= 1
- byte or item counts that logically can't be negative
- port numbers that should be in 1..0xffff
Many options in Prosody that are treated as numbers don't make sense as
floats, e.g. sizes and limits measured in bytes.
Simplified implementation based on an earlier attempt dating back to 2020
Because it changes the type of the 'opt_origins' variable from util.set
to the internal _items table so next time an http app is added an error
"attempt to call a nil value (method 'empty')" is triggered. The value
is not used anywhere else.
Noticed when reviewing uses of the '_items' set property.
Not reported by any users, implying this setting is rarely used.
Where gethostname or tohostname returns an invalid name, e.g. containing
underscores or something, to_ascii would reject this and return nil,
which triggers an error in the dns lookup.
Reported by prova2 in the chat, for whom tohostname returned a long name
containing underscores.
Could be used to implement custom connection methods (c.f. mod_onions)
without needing to duplicate the rest of route_to_new_session().
Adds a feature to enable detection since it can be difficult to detect
support for an event otherwise.
It should not be there afterwards. Noticed that it seems to fire some
time after resumption claiming that the queue size is nil, implying
that it may hold a reference to an expired session somehow.
Error stanzas should have an <error> element, but if you pass a
stanza without one to util.error.from_stanza() it triggers an attempt to
index a nil value, which this patch avoids.
In the conditional, it should be safe to assume error_tag is non-nil
since condition can't have those values then.
There shouldn't be one here but if there is, for some reason, it's
better to close it than have it around to wake up and possibly try to
destroy the session.
The cross_domain_* settings were added here prior to http_cors_override
being added back in 17d87fb2312a, so for a time there was no
replacement, but now there is.
This event was added in a7c183bb4e64 and is required to make mod_smacks know
that a session was intentionally closed and shouldn't be hibernated (see
fcea4d9e7502).
Because this was missing from mod_websocket's session.close(), mod_smacks
would always attempt to hibernate websocket sessions even if they closed
cleanly.
That mod_websocket has its own copy of session.close() is something to fix
another day (probably not in the stable branch). So for now this commit makes
the minimal change to get things working again.
Thanks to Damian and the Jitsi team for reporting.
When mod_admin_socket is loaded without mod_admin_shell, attempt to use
`prosodyctl shell` will appear to freeze after any input, since no
response is returned.
This information is sometimes necessary in the context where we have a
connection that we know (or believe to be) associated with an incoming HTTP
request.
For example, it can be used to retrieve the IP address of a request (which may
differ from the IP address of the connection, due to X-Forwarded-For and co).
Thanks to the Jitsi team for highlighting this gap in the API.
This ensures that we support responses without a content-length header, and
allow streaming them through the streaming handler interface. An example of
such a response would be Server-Sent Events streams.
On regular disconnects, </stream> is sent, then
sessionmanager.destroy_session() is called, then
sessionmanager.destroy_session() is called again when the TCP connection
is closed, from ondisconnect in mod_c2s.
It is a bit annoying and doesn't really tell you much.
Ensures a last round of garbage collection and that finalizers are
called. Fixes things like proper closing of SQLite3 state.
There are more calls to os.exit() but most of them exit with an error or
in a case where a final GC sweep might not matter as much.
It would be nice if this was the default.
Calling util.statup.exit() everywhere may be sensible, but would be more
involved, requiring imports everywhere.
This ensures a last round of garbage collection and finalizers, which
should include flushing the readline history file.
Test procedure:
```
$ ./prosodyctl shell
prosody> s2s:show() -- any command that is not the last in history
... output
prosody> bye
$ ./prosodyctl shell
prosody> ^P
```
After this, the shell prompt should contain the last command from before
the "bye". Before this patch, recent history is gone most of the time.
