There is no reason any more to use the x- options, and I think libvirt never used them anyway. I actually have a commit in my QAPI object branch that removes these properties, but I think it still broke some tests. Anyway, something for a separate patch. Kevin

The doc comment language is the result of a series of pragmatic decisions that got us from semi-accidental comment conventions to where we are now. Each of the decisions made sense at the time.

I'll have to read Marc-Andre's recent sphinx patches and see if I want to do more work -- I had a bigger prototype a few months back I didn't bring all the way home, but I am still thinking about reworking our QAPIDoc format. It's ... well.

(2) ...but the Sphinx internals are really not meant to be used the way we're using them right now, ... (3) ...but I also don't want to write our QAPI docstrings in a way that *targets* Sphinx. Not that I think we'll be dropping it any time soon, but it still feels like the wrong idea to tie them so closely together. I'm hoping there's an opportunity to make the parsing nicer with minimal changes to the parsing and format, though. It just might require enforcing a *pinch* more structure. I could see how I feel about per-field annotations at that point. I consider them interesting for things like the Python SDK where I may want to enable/disable warnings for using deprecated stuff at the client-level. (e.g., let's say you're using Python SDK 6.2 to talk to a 6.1 client. Nothing stops you from doing this, but some commands will simply be rejected by QEMU as it won't know what you're talking about. Using deprecated fields or commands to talk to an older client will produce no visible warning from QEMU either, as it wasn't deprecated at that point in time. Still, the client may wish to know that they're asking for future trouble -- so it's a thought that client-side warnings have some play here.) E don't worry about it for now, I guess I'll plow forward a bit with the Sphinx stuff I'm thinking of at some point Soon:tm: and worry about where the immovable objects are when I get there.

When Kevin invented feature flags (merge commit 4747524f9f2), he added them just to struct types. He added "feature sections" for documenting features. It mirrors the "argument sections" for documenting members. Makes sense. Aside: he neglected to update qapi-code-gen.rst section "Definition documentation", and I failed to catch it. I'll make up for it. Peter and I then added feature flags to the remaining definitions (commit 23394b4c39 and 013b4efc9b). Feature sections make sense there, too.

This conflates member features with struct features. What could "something fancy" be? All we have for members is "argument sections", which are basically a name plus descriptive text. We'd have to add structure to that, say nest feature sections into argument sections.

I'm pretty sure the x- names that don't get feature 'unstable' are actually stable; see my reply to Kashyap. I did check git history for each that does get feature 'unstable'.
