The Metadata query function -executes an external query tool appropriate to the current workspace. - -Loading packages always returns the complete import graph "all the way down", -even if all you want is information about a single package, because the query -mechanisms of all the build systems we currently support ({go,vgo} list, and -blaze/bazel aspect-based query) cannot provide detailed information -about one package without visiting all its dependencies too, so there is -no additional asymptotic cost to providing transitive information. -(This property might not be true of a hypothetical 5th build system.) - -In calls to TypeCheck, all initial packages, and any package that -transitively depends on one of them, must be loaded from source. -Consider A->B->C->D->E: if A,C are initial, A,B,C must be loaded from -source; D may be loaded from export data, and E may not be loaded at all -(though it's possible that D's export data mentions it, so a -types.Package may be created for it and exposed.) - -The old loader had a feature to suppress type-checking of function -bodies on a per-package basis, primarily intended to reduce the work of -obtaining type information for imported packages. Now that imports are -satisfied by export data, the optimization no longer seems necessary. - -Despite some early attempts, the old loader did not exploit export data, -instead always using the equivalent of WholeProgram mode. This was due -to the complexity of mixing source and export data packages (now -resolved by the upward traversal mentioned above), and because export data -files were nearly always missing or stale. Now that 'go build' supports -caching, all the underlying build systems can guarantee to produce -export data in a reasonable (amortized) time. - -Test "main" packages synthesized by the build system are now reported as -first-class packages, avoiding the need for clients (such as go/ssa) to -reinvent this generation logic. - -One way in which go/packages is simpler than the old loader is in its -treatment of in-package tests. In-package tests are packages that -consist of all the files of the library under test, plus the test files. -The old loader constructed in-package tests by a two-phase process of -mutation called "augmentation": first it would construct and type check -all the ordinary library packages and type-check the packages that -depend on them; then it would add more (test) files to the package and -type-check again. This two-phase approach had four major problems: -1) in processing the tests, the loader modified the library package, - leaving no way for a client application to see both the test - package and the library package; one would mutate into the other. -2) because test files can declare additional methods on types defined in - the library portion of the package, the dispatch of method calls in - the library portion was affected by the presence of the test files. - This should have been a clue that the packages were logically - different. -3) this model of "augmentation" assumed at most one in-package test - per library package, which is true of projects using 'go build', - but not other build systems. -4) because of the two-phase nature of test processing, all packages that - import the library package had to be processed before augmentation, - forcing a "one-shot" API and preventing the client from calling Load - in several times in sequence as is now possible in WholeProgram mode. - (TypeCheck mode has a similar one-shot restriction for a different reason.) - -Early drafts of this package supported "multi-shot" operation. -Although it allowed clients to make a sequence of calls (or concurrent -calls) to Load, building up the graph of Packages incrementally, -it was of marginal value: it complicated the API -(since it allowed some options to vary across calls but not others), -it complicated the implementation, -it cannot be made to work in Types mode, as explained above, -and it was less efficient than making one combined call (when this is possible). -Among the clients we have inspected, none made multiple calls to load -but could not be easily and satisfactorily modified to make only a single call. -However, applications changes may be required. -For example, the ssadump command loads the user-specified packages -and in addition the runtime package. It is tempting to simply append -"runtime" to the user-provided list, but that does not work if the user -specified an ad-hoc package such as [a.go b.go]. -Instead, ssadump no longer requests the runtime package, -but seeks it among the dependencies of the user-specified packages, -and emits an error if it is not found. - -Overlays: The Overlay field in the Config allows providing alternate contents -for Go source files, by providing a mapping from file path to contents. -go/packages will pull in new imports added in overlay files when go/packages -is run in LoadImports mode or greater. -Overlay support for the go list driver isn't complete yet: if the file doesn't -exist on disk, it will only be recognized in an overlay if it is a non-test file -and the package would be reported even without the overlay. - -Questions & Tasks - -- Add GOARCH/GOOS? - They are not portable concepts, but could be made portable. - Our goal has been to allow users to express themselves using the conventions - of the underlying build system: if the build system honors GOARCH - during a build and during a metadata query, then so should - applications built atop that query mechanism. - Conversely, if the target architecture of the build is determined by - command-line flags, the application can pass the relevant - flags through to the build system using a command such as: - myapp -query_flag="--cpu=amd64" -query_flag="--os=darwin" - However, this approach is low-level, unwieldy, and non-portable. - GOOS and GOARCH seem important enough to warrant a dedicated option. - -- How should we handle partial failures such as a mixture of good and - malformed patterns, existing and non-existent packages, successful and - failed builds, import failures, import cycles, and so on, in a call to - Load? - -- Support bazel, blaze, and go1.10 list, not just go1.11 list. - -- Handle (and test) various partial success cases, e.g. - a mixture of good packages and: - invalid patterns - nonexistent packages - empty packages - packages with malformed package or import declarations - unreadable files - import cycles - other parse errors - type errors - Make sure we record errors at the correct place in the graph. - -- Missing packages among initial arguments are not reported. - Return bogus packages for them, like golist does. - -- "undeclared name" errors (for example) are reported out of source file - order.
