Modifies the CI build to integrate the GitHub Action-based test runner from the [XMPP Interop Testing project](https://xmpp-interop-testing.github.io). This executes additional integration tests that help verify ejabberd's compliance with XMPP specifications.
In this commit, none of the tests are excluded, which likely results in false positives. Therefor, the 'continue-on-error' flag is set. This should ideally be removed in a later commit.
So far, ejabberd_update:update/0 returned the return value of
release_handler_1:eval_script/1. That function returns the list of
updated but unpurged modules, i.e., modules where one or more processes
are still running an old version of the code. Since commit
5a34020d23, the ejabberd 'update' command
assumes that value to be the list of updated modules instead. As
that seems more useful, modify ejabberd_update:update/0 accordingly.
This fixes the 'update' command output.
Since commit 514c25caef, whenever a PEP
item was published, a notification was blindly sent back to the owner.
However, this should only be done subject to +notify filtering, as per
XEP-0163:
| the PEP service shall send notifications to all of the account owner's
| available resources (subject to notification filtering).
The motivation for the mentioned commit was that +notify subscriptions
initially didn't work for PEP node owners (#2108). However, that issue
was fixed by commit 5968bc9318 (#2112).
As a result, the owner's client was actually notified twice if the
client was subscribed to the node (e.g., via +notify).
Therefore, just omit the additional, blind notification.
Thanks to W. Martin Borgert and Daniel Gultsch for reporting the issue.
This removes handling of pre-rfc7395 encapsulation of xmpp in websocket
(where data send in websocket was using just raw data as send in regular
socket). This didn't work correctly for last 5 years, and as we didn't
see complains about this, we can assume it's not used anymore.
Let's disable the tests that would require major changes in existing
ejabberd source code, and fixing them would produce a curtain of changes
that would difficult using git blame and git log, but provide minimal
benefits.
Don't check erlang header files by now.
Don't check rebar.config because it has customizations that must be
parsed by rebar.config.script to have suitable syntax.
This allows connections to server that have both xmpps-server and xmpp-server
srv entries, for which xmpps version doesn't work correctly. Before this
change we would stop on non-working xmpps server, now we will also attempt
to connect further servers on list.
