core.moduleapi: Filter out unrelated direct replies to module:send_iq This is primarily something that happens with an internal query to mod_mam, which calls origin.send() several times with results, leading to the first such result being treated as the final response and resolving the promise. Now, these responses pass trough to the underlying origin.send(), where they can be caught. Tricky but not impossible. For remote queries, it's even trickier, you would likely need to bind a resource or similar.

-- Storage Interface API Description
--
-- This is written as a TypedLua description

-- Key-Value stores (the default)

interface keyval_store
	get : ( self, string? ) -> (any) | (nil, string)
	set : ( self, string?, any ) -> (boolean) | (nil, string)
end

-- Map stores (key-key-value stores)

interface map_store
	get : ( self, string?, any ) -> (any) | (nil, string)
	set : ( self, string?, any, any ) -> (boolean) | (nil, string)
	set_keys : ( self, string?, { any : any }) -> (boolean) | (nil, string)
	remove : {}
end

-- Archive stores

typealias archive_query = {
	"start"  : number?, -- timestamp
	"end"    : number?, -- timestamp
	"with"   : string?,
	"after"  : string?, -- archive id
	"before" : string?, -- archive id
	"total"  : boolean?,
}

interface archive_store
	-- Optional set of capabilities
	caps   : {
		-- Optional total count of matching items returned as second return value from :find()
		"total" : boolean?,
	}?

	-- Add to the archive
	append : ( self, string?, string?, any, number?, string? ) -> (string) | (nil, string)

	-- Iterate over archive
	find   : ( self, string?, archive_query? ) -> ( () -> ( string, any, number?, string? ), integer? )

	-- Removal of items. API like find. Optional?
	delete : ( self, string?, archive_query? ) -> (boolean) | (number) | (nil, string)

	-- Array of dates which do have messages (Optional?)
	dates  : ( self, string? ) -> ({ string }) | (nil, string)

	-- Map of counts per "with" field
	summary : ( self, string?, archive_query? ) -> ( { string : integer } ) | (nil, string)

	-- Map-store API
	get    : ( self, string, string ) -> (stanza, number?, string?) | (nil, string)
	set    : ( self, string, string, stanza, number?, string? ) -> (boolean) | (nil, string)
end

-- This represents moduleapi
interface module
	-- If the first string is omitted then the name of the module is used
	-- The second string is one of "keyval" (default), "map" or "archive"
	open_store : (self, string?, string?) -> (keyval_store) | (map_store) | (archive_store) | (nil, string)

	-- Other module methods omitted
