From e4a9b44f7aa8872a67a54a71da474626cdbb830a Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Fri, 28 Jun 2024 13:27:56 +0200 Subject: [PATCH] sphinx/qapidoc: Fix to generate doc for explicit, unboxed arguments When a command's arguments are specified as an explicit type T, generated documentation points to the members of T. Example: ## # @announce-self: # # Trigger generation of broadcast RARP frames to update network [...] ## { 'command': 'announce-self', 'boxed': true, 'data' : 'AnnounceParameters'} generates "announce-self" (Command) ------------------------- Trigger generation of broadcast RARP frames to update network [...] Arguments ~~~~~~~~~ The members of "AnnounceParameters" Except when the command takes its arguments unboxed , i.e. it doesn't have 'boxed': true, we generate *nothing*. A few commands have a reference in their doc comment to compensate, but most don't. Example: ## # @blockdev-snapshot-sync: # # Takes a synchronous snapshot of a block device. # # For the arguments, see the documentation of BlockdevSnapshotSync. [...] ## { 'command': 'blockdev-snapshot-sync', 'data': 'BlockdevSnapshotSync', 'allow-preconfig': true } generates "blockdev-snapshot-sync" (Command) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Takes a synchronous snapshot of a block device. For the arguments, see the documentation of BlockdevSnapshotSync. [...] Same for event data. Fix qapidoc.py to generate the reference regardless of boxing. Delete now redundant references in the doc comments.
