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.
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.
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.
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.
Allowed by XML despite arguably being a control character.
Drops the part of the range meant to rule out octets invalid in UTF-8
(\247 starts a 4-byte sequence), since UTF-8 correctness is validated by
util.encodings.utf8.valid().
The JSON Schema specification says that schemas are objects or booleans,
and that the 'type' property is optional and can be an array.
This module previously allowed bare type names as schemas and did not
really handle booleans.
It now handles missing 'type' properties and boolean 'true' as a schema.
Objects and arrays are guessed based on the presence of 'properties' or
'items' field.
MattJ reported a curious issue where validation did not work as
expected. Primarily that the "type" field was expected to be mandatory,
and thus leaving it out would result in no checks being performed.
This was likely caused by misreading during initial development.
Spent some time testing against
https://github.com/json-schema-org/JSON-Schema-Test-Suite.git and
discovered a multitude of issues, far too many to bother splitting into
separate commits.
More than half of them fail. Many because of features not implemented,
which have been marked NYI. For example, some require deep comparisons
e.g. when objects or arrays are present in enums fields.
Some because of quirks with how Lua differs from JavaScript, e.g. no
distinct array or object types. Tests involving fractional floating
point numbers. We're definitely not going to follow references to remote
resources. Or deal with UTF-16 sillyness. One test asserted that 1.0 is
an integer, where Lua 5.3+ will disagree.
Observed problem: When shutting down prosody would immediately exit
after waiting for s2s connections to close, skipping the last cleanup
events and reporting the exit reason and code.
This happens because prosody.main_thread is in a waiting state and
queuing startup.shutdown is dispatched trough the main loop via
nexttick, but since the main loop was no longer running at that point it
proceeded to the end of the prosody script and exited there.
The second return value is (not insensibly) assumed to be an error. Instead of
returning a value there in the success case, copy the positional arguments
into the existing opts table.
This is the same as the input table (which is mutated during processing), but
if that table was created on the fly, such as by packing `...` it's convenient
if it also gets returned from the parse function.
util.crand can be configured at compile time to use the Linux
getrandom() system call, available from Linux 3.17, but it is still
possible to load it with an older kernel lacking that system call, where
attempting to use it throws an ENOSYS error.
By testing for this on load we can fall back to /dev/urandom in this
case.
The "socket.unix" module exported only a function before
aa1b8cc9bc
when datagram support was added.
Fixes#1717
Thanks rsc and lucas for reporting and testing
Some NATs don't preserve port numbers, which can cause the TURN server's
reported relay address to be incorrect (the TURN server has no way to predict
what the external port is, so it can't be corrected in config like an IP
mismatch can).
