util.xml: Deduplicate handlers for restricted XML Makes the code more like util.xmppstream, allowing easier comparisons if we ever need to apply fixes in the future.

util.xml: Break reference to help the GC (fix #1711) LuaExpat uses a registry reference to track handlers, which makes it so that an upvalue like this creates a reference loop that keeps the parser and its handlers from being garbage collected. The same issue has affected util.xmppstream in the past. Code for checking: local xml_parse = require"util.xml".parse; for i = 1, 10000 do xml_parse("<root/>") end collectgarbage(); collectgarbage(); print(collectgarbage("count"), "KiB"); A future release of LuaExpat may fix the underlying issue there.

util.prosodyctl.cert: Check success of copy operations, warn on fail Debugging a case where certs are not imported correctly but prosodyctl still reports success. Hoping this will shed some light on it.

util.prosodyctl.cert: Pass variables via formatting instead of concatenation Prevents potential weirdness in case there's any %s or such in a host, file or directory name, since show_warning() is printf().

tools/xep227toprosody: Remove obsolete tool in favor of storage driver This tool hasn't been updated for recent XEP-0227 changes, hasn't seen many changes at all since its introduction and I don't remember anyone mentioning ever using it. Using mod_storage_xmlarchive and the migrator or the 3rd party mod_migrate tool should work better these days and should be the way forward.

core.certmanager: Use 'tls_profile' instead of 'tls_preset' to match documentation Confusion! Thanks Martin

core.certmanager: Apply TLS preset before global settings (thanks Menel) Allows overriding settings via the global 'ssl' settings as before. This order was probably accidental. That said, 'ssl' is a giant footgun we will want to discourage use of.
