81d747b6a4 util.smqueue: Add missing method to Teal record spec 2021-12-16 12:16:08 +01:00

93a9ed2620 util.smqueue: Abstract queue with acknowledgements and overflow 
Meant to be used in mod_smacks for XEP-0198

Meant to have a larger virtual size than actual number of items stored,
on the theory that in most cases, the excess will be acked before needed
for a resumption event.

d6070eea1f mod_cron: Initialize timestamp of new tasks to start of period 
Makes it more generic so new periods (e.g. weekly etc) can be added
easily.

6f3409f3f2 mod_cron: Initialize daily tasks so they run around midnight UTC 
Eventually the goal is to have daily tasks run while there is little
activity, but that will vary with the server and the usage patterns of
its users. This is a start anyway.

630035a369 mod_cron: Initial commit of periodic task runner 
A number of modules now have periodic tasks that need to run, e.g. for
cleaning out old messages or files. This has highlighted a need for
coordinating and optimizing scheduling of such tasks.

4720eea24f util.datamapper: Don't include empty unwrapped arrays 
Since there is no way to distinguish an empty such array from a
zero-length array. Dropping it seems like the least annoying thing to
do.

13185a16ae util.datamapper: Fix error on attempt to coerce nil to something 
Turns falsy values into nil instead of nothing, which ensures this
function always has 1 return value, or table.insert({}) complains. Would
still happen on some unexpected input, but that's actually a good thing.

2040145780 util.datamapper: Deal with locally built stanzas missing xmlns 
So the problem is that xmlns is not inherited when building a stanza,
and then :get_child(n, ns) with an explicit namespace does not find that
such child tags.

E.g.
local t = st.stanza("foo", { xmlns = "urn:example:bar" })
	:text_tag("hello", "world");
assert(t:get_child("hello", "urn:example:bar"), "This fails");

Meanwhile, during parsing (util.xmppstream or util.xml) child tags do
get the parents xmlns when not overriding them.

Thus, in the above example, if the stanza is passed trough
`t = util.xml.parse(tostring(t))` then the assert succeeds.

This change makes it so that it leaves out the namespace argument to
:get_child when it is the same as the current/parent namespace, which
behaves the same for both built and parsed stanzas.

87474145e5 util.datamapper: Factor out extraction of the XML part to use 
So extract_value() takes an XML tag and details about which part we're

Factoring this out will help with array implementation since this will
be common behavior.

3a62af2e0e util.datamapper: Separate extraction of xml from coercion to target type

whatever the schema wants. This should be easier to further factor out
into preparation for array support.

5a44c4a32b util.jsonschema: Allow a boolean as schema

6a7346ac8e util.jsonschema: Correct "items" keyword

that from.
