Package checker is a driver for the analysis API.
It is an internal package, but is exposed by three different APIs:
analysistest, singlechecker, and multichecker.
Checker uses go/packages to load the specified packages (plus their
dependencies, if any analysis uses facts) from source code.
It constructs a graph of actions (analysis passes), whose dependency
edges may be "horizontal", when one analyzer depends on the output of
another applied to the same package, or "vertical", when an an
analyzer consumes facts produced by the same analyzer applied to a
dependency package.
The graph is executed in parallel, unless -debug=p.
Facts are passed from one pass to another in memory.
If -debug=s, facts are serialized, to exercise that logic.
Findings are printed at the end.
The -json flag selects JSON output.
Use -debug=t to print timing information.
Always use -debug=tp, for sequential mode, when timing.
Also:
- analysistest: a wrapper for testing checkers
- multichecker: a wrapper for writing multi-checker tools
Analysis flags are prefixed by name: -findcall.name=foo.
- cmd/analyze: a command-line tool based on multichecker
- singlechecker: a wrapper for writing single-checker tools
Analysis flags are unprefixed: -name=foo.
- passes/findcall/cmd/findcall: a standalone tool for the findcall analysis
- tests for findcall
- tests for pkgfact

For all packages p, q where there's an dependency path of

q [p.test] of each q and replaces the dependency on q with
a dependency on q [p.test], and replaces p with the expanded
test variant p[p.test]. Fix the fallback logic to add
these missing test variants. (Before this change, it was
only producing the variant of p: p [p.test].)

field of the corresponding Package.
Clients are responsible for printing or otherwise handling errors.

Rather than document the range of possible error types, requiring
clumsy client code to extract position information, we now expose a
single concrete type for all errors. Position information (in
standardized string form) is technically optional, but we should
strive for 100%, fixing gaps as they arise.
This change enables us to unify the Package and JSON structs in a
follow-up.
Question: should we eliminate the Config.Error hook and be silent by default?
Pro:
+ most clients suppress it.
Con:
- clients that want to print errors (e.g. vet-like tools) would have
to traverse the entire import graph to find them.
- silence is not the most fail-safe behavior.
