passing the --post_build_query flag to a build command, with a query expression as the argument. Bazel then executes this query on the configured target graph as constructed by the build command.
Since the prepare graph -> query workflow is how SkyQueryEnvironment works, this is mostly just copying that.
Main missing features/code cleanups:
* Recursive target patterns (/...) are not supported.
* There is no way to specify the configuration of the targets in your query.
* Configuration output is totally opaque (just the hash, or null if no configuration).
* More generally, no output options.
* Some features (visibility, label attrs) not supported.
* No edge filtering (host deps, implicit deps).
* Aspects are totally ignored.
* Graceful failure on errors, edge cases, incompatible flags (like the TAP flags that discard edges).
* Code hygiene issues (calling test-only method to get to Skyframe graph, some code duplication across ConfiguredTargetQueryEnvironment and SkyQueryEnvironment).
Most of the features I plan to leave to rules-side people, since I think they won't be too hard for a general Blaze developer to implement, and designing the right features and user interfaces for these things is better left to the rules side.
