* docs/qapi-domain: add return-nodescJohn Snow2025-07-141-0/+8
| | | | | | | | | | | | | | | | | | | | | This form is used to annotate a return type without an accompanying description, for when there is no "Returns:" information in the source doc, but we have a return type we want to generate a cross-reference to. The syntax is: :return-nodesc: TypeName It's primarily necessary because Sphinx always expects both a type and a description for the prior form and will format it accordingly. To have a reasonable rendering when the body is missing, we need to use a different info field list entirely.

* docs/qapidoc: linting fixesJohn Snow2025-06-051-11/+14
| | | | | | | | | | | | | | | | | This restores the linting baseline in qapidoc. The order of some imports change slightly here due to configuring isort a little better: previously, isort was having difficulty understanding that "compat" and "qapidoc_legacy" were local modules because docs/sphinx "isn't a python package". Configuring this manually, isort chooses a different import ordering, which _is_ intentional here. Also: extra ignores are added for pylint. The most recent versions of pylint don't require these ignores, but the oldest versions we support do, so in the extra ignores go.

* docs/qapi-domain: add namespaced index supportJohn Snow2025-03-141-14/+37
| | | | | | | | | | | | | | | | | | | Generate an index-per-namespace for the QAPI domain. Due to a limitation with Sphinx's architecture, these indices must be defined during setup time and cannot be dynamically created on-demand when a namespace directive is encountered. Owing to that limitation, add a configuration value to conf.py that specifies which QAPI namespaces we'll generate indices for. Indices will be named after their namespace, e.g. the "QMP" namespace will generate to "qapi-qmp-index.html" and can be referenced using `qapi-qmp-index`.

* docs/qapi_domain: add namespace support to cross-referencesJohn Snow2025-03-141-43/+84
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does three things: 1. Record the current namespace context in pending_xrefs so it can be used for link resolution later, 2. Pass that recorded namespace context to find_obj() when resolving a reference, and 3. Wildly and completely rewrite find_obj(). cross-reference support is expanded to tolerate the presence or absence of either namespace or module, and to cope with the presence or absence of contextual information for either. References now work like this: 1. If the explicit reference target is recorded in the domain's object registry, we link to that target and stop looking. We do this lookup regardless of how fully qualified the target is, which allows direct references to modules (which don't have a module component to their names) or direct references to definitions that may or may not belong to a namespace or module. 2. If contextual information is available from qapi:namespace or qapi:module directives, try using those components to find a direct match to the implied target name. 3. If both prior lookups fail, generate a series of regular expressions looking for wildcard matches in order from most to least specific. Any explicitly provided components (namespace, module) *must* match exactly, but both contextual and entirely omitted components are allowed to differ from the search result. Note that if more than one result is found, Sphinx will emit a warning (a build error for QEMU) and list all of the candidate references. The practical upshot is that in the large majority of cases, namespace and module information is not required when creating simple `references` to definitions from within the same context -- even when identical definitions exist in other contexts. Even when using simple `references` from elsewhere in the QEMU documentation manual, explicit namespace info is not required if there is only one definition by that name. Disambiguation *will* be required from outside of the QAPI documentation when referencing e.g. block-core definitions, which are shared between QEMU QMP and the QEMU Storage Daemon. In that case, there are two options: A: References can be made partially or fully explicit, e.g. `QMP:block-dirty-bitmap-add` will link to the QEMU version of the definition, while `QSD:block-dirty-bitmap-add` would link to the QSD version. B: If all of the references in a document are intended to go to the same place, you can insert a "qapi:namespace:: QMP" directive to influence the fuzzy-searching for later references.

* docs/qapi-domain: add qapi:namespace directiveJohn Snow2025-03-141-0/+13
| | | | | | | | | | | | | | | | | Add a new directive that marks the beginning of a QAPI "namespace", for example; "QMP", "QGA" or "QSD". This directive will associate all subsequent QAPI directives in a document with the specified namespace. This does not change the visual display of any of the definitions or index entries, but does change the "Fully Qualified Name" inside the QAPI domain's object table. This allows for two different "namespaces" to define entities with otherwise identical names -- which will come in handy for documenting both QEMU QMP and the QEMU Storage Daemon.

* docs/qapi-domain: add :namespace: override optionJohn Snow2025-03-141-2/+3
| | | | | | | | | | | | | | | | | | Akin to the :module: override option, the :namespace: options allows you to forcibly override the contextual namespace associatied with a definition. We don't necessarily actually need this, but I felt compelled to stick close to how the Python domain works that offers context overrides. As of this commit, it is possible to add e.g. ":namespace: QMP" to any QAPI directive to forcibly associate that definition with a given namespace.

| | | | | | | | | | | | | | | | Currently, only the definition name is stored in the tree metadata; but the node property is confusingly called "fullname". Rectify this by always storing the FQN in the tree metadata. ... While we're here, re-organize the code in preparation for namespace support to make it a bit easier to add additional components of the FQN.

* docs/qapidoc: Add "the members of" pointersJohn Snow2025-03-111-2/+20
| | | | | | | | | | | | | | | | | | | | | | | | Add "the members of ..." pointers to Members and Arguments lists where appropriate, with clickable cross-references - so it's a slight improvement over the old system :) This patch is meant to be a temporary solution until we can review and merge the inliner. The implementation of this patch is a little bit of a hack: Sphinx is not designed to allow you to mix fields of different "type"; i.e. mixing member descriptions and free-form text under the same heading. To accomplish this with a minimum of hackery, we technically document a "dummy field" and then just strip off the documentation for that dummy field in a post-processing step. We use the "q_dummy" variable for this purpose, then strip it back out before final processing. If this processing step should fail, you'll see warnings for a bad cross-reference. (So if you don't see any, it must be working!)

* docs/qapi-domain: Fix error context reporting in Sphinx 5.x and 6.xJohn Snow2025-03-111-6/+9
| | | | | | | | | | | | | | | | | | | | | | | | | Sphinx 5.3.0 to Sphinx 6.2.0 has a bug where nested content in an ObjectDescription content block has its error position reported incorrectly due to an oversight when they added nested section support to this directive. (This bug is present in Sphinx's own Python and C domains; test it yourself by creating a py:func directive and creating a syntax error in the directive's content block. The reporting will be incorrect.) To avoid overriding and re-implementing the entirety of the run() method, a workaround is employed where we parse the content block ourselves in before_content(), then null the content block to make Sphinx's own parsing a no-op. Then, in transform_content (which occurs after Sphinx's nested parse), we simply swap our own parsed content tree back in for Sphinx's. It appears a little tricky, but it's the nicest solution I can find.

* docs/qapi-domain: warn when QAPI domain xrefs fail to resolveJohn Snow2025-03-111-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds a warning (which is a build failure under our current build settings) whenever a QAPI cross-reference fails to resolve. This applies to any cross-references of the form :qapi:{role}:`foo`, which covers all of the automatically generated references by the qapi domain, and any such references that are manually written into the documentation rst files. Cross-references of the form `foo` do not use this system, but are already configured to issue a warning (Again, a build failure) if the cross-reference isn't found anywhere. Adds warnings that look like the following: docs/qapi/index.rst:48: WARNING: qapi:type reference target not found: 'footype' [ref.qapi] docs/qapi/index.rst:50: WARNING: qapi:mod reference target not found: 'foomod' [ref.qapi] Signed-off-by: John Snow <jsnow@redhat.com> Message-ID: <20250311034303.75779-31-jsnow@redhat.com> Acked-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>

* docs/qapi-domain: add type cross-refs to field listsJohn Snow2025-03-111-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit, finally, adds cross-referencing support to various field lists; modeled tightly after Sphinx's own Python domain code. Cross-referencing support is added to type names provided to :arg:, :memb:, :returns: and :choice:. :feat:, :error: and :value:, which do not take type names, do not support this syntax. The general syntax is simple: :arg TypeName ArgName: Lorem Ipsum ... The domain will transform TypeName into :qapi:type:`TypeName` in this basic case, and also apply the ``literal`` decoration to indicate that this is a type cross-reference. For optional arguments, the special "?" suffix is used. Because "*" has special meaning in rST that would cause parsing errors, we elect to use "?" instead. The special syntax processing strips this character from the end of any type name argument and will append ", optional" to the rendered output, applying the cross-reference only to the actual type name. The intent here is that the actual syntax in doc-blocks need not change; but e.g. qapidoc.py will need to process and transform "@arg foo lorem ipsum" into ":arg type? foo: lorem ipsum" based on the schema information. Therefore, nobody should ever actually witness this intermediate syntax unless they are writing manual documentation or the doc transmogrifier breaks. For array arguments, type names can similarly be surrounded by "[]", which are stripped off and then re-appended outside of the cross-reference.

* docs/qapi-domain: add warnings for malformed field listsJohn Snow2025-03-111-0/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Normally, Sphinx will silently fall back to its standard field list processing if it doesn't match one of your defined fields. A lot of the time, that's not what we want - we want to be warned if we goof something up. For instance, the canonical argument field list form is: :arg type name: descr This form is captured by Sphinx and transformed so that the field label will become "Arguments:". It's possible to omit the type name and descr and still have it be processed correctly. However, if you omit the type name, Sphinx no longer recognizes it: :arg: this is not recognized. This will turn into an arbitrary field list entry whose label is "Arg:", and it otherwise silently fails. You may also see failures for doing things like using :values: instead of :value:, or :errors: instead of :error:, and so on. It's also case sensitive, and easy to trip up. Add a validator that guarantees all field list entries that are the direct child of an ObjectDescription use only recognized forms of field lists, and emit a warning (treated as error by default in most build configurations) whenever we detect one that is goofed up. However, there's still benefit to allowing arbitrary fields -- they are after all not a Sphinx invention, but perfectly normal docutils syntax. Create an allow list for known spellings we don't mind letting through, but warn against anything else.

* docs/qapi-domain: add qapi:module directiveJohn Snow2025-03-111-6/+65
| | | | | | | | | | | | | | | | | | | | | | | This adds the qapi:module directive, which just notes the current module being documented and performs a nested parse of the content block, if present. This code is based pretty heavily on Sphinx's PyModule directive, but with unnecessary features excised. For example: .. qapi:module:: block-core Hello, and welcome to block-core! ================================= lorem ipsum, dolor sit amet ...

* docs/qapi-domain: Add QAPIDescription abstract classJohn Snow2025-03-111-2/+99
| | | | | | | | | | | | | | | | | This class is a generic, top-level directive for documenting some kind of QAPI thingamajig that we expect to go into the Index. This class doesn't do much by itself, and it isn't yet associated with any particular directive. handle_signature(), _object_hierarchy_parts() and _toc_entry_name() are defined in the base class. get_index_text() and add_target_and_index() are new methods defined here; they are based heavily on the layout and format of the Python domain's general object class.

* docs/qapi-domain: add QAPI xref rolesJohn Snow2025-03-111-1/+87
| | | | | | | | | | | | | | | | | | | Add domain-specific cross-reference syntax. As of this commit, that means new :qapi:any:`block-core` referencing syntax. The :any: role will find anything registered to the QAPI domain, including modules, commands, events, etc. Creating the cross-references is powered by the QAPIXRefRole class; resolving them is handled by QAPIDomain.resolve_xref(). QAPIXrefRole is based heavily on Sphinx's own PyXrefRole, with modifications necessary for QAPI features.

* docs/qapi-domain: add resolve_any_xref()John Snow2025-03-111-3/+93
| | | | | | | | | | | | | | | | | Add the ability to resolve cross-references using the `any` cross-reference syntax. Adding QAPI-specific cross-reference roles will be added in a forthcoming commit, and will share the same find_obj() helper. (There's less code needed for the generic cross-reference resolver, so it comes first in this series.) Once again, this code is based very heavily on sphinx.domains.python.

* docs/qapi-domain: add QAPI indexJohn Snow2025-03-111-3/+70
| | | | | | | | | | | | | | Use the QAPI object registry to generate a special index just for QAPI definitions. The index can show entries both by definition type and all together, alphabetically. The index can be linked from anywhere in the QEMU manual by using the reference `qapi-index`.

* docs/qapi-domain: add QAPI domain object registryJohn Snow2025-03-111-2/+75
| | | | | | | | | | | | | | | | | | | This is the first step towards QAPI domain cross-references and a QAPI reference index. This patch just creates the object registry, and updates the merge_domaindata stub method now that we have actual data we may need to merge. Note that how to handle merge conflict resolution is unhandled, as the Sphinx python domain itself does not handle it either. I do not know how to intentionally trigger it, so I've left an assertion instead if it should ever come up ...

* docs/sphinx: create QAPI domain extension stubJohn Snow2025-03-111-0/+56
A Sphinx domain is a collection of directive and role extensions meant to facilitate the documentation of a specific language. For instance, Sphinx ships with "python" and "cpp" domains. This patch introduces a stub for the "qapi" language domain. Please see https://www.sphinx-doc.org/en/master/usage/domains/index.html for more information. This stub doesn't really do anything yet, we'll get to it brick-by-brick in the forthcoming commits to keep the series breezy and the git history informative.
