For a 'definition' query on X in p.X, use special logic to load and
parse package p and find the declaration of package member X, without
using the type checker. Such queries now typically take under
10ms (faster than godef).
The logic assumes that import "something/p" defines the name p. If this
assumption is false, p.X could be a selection of a field or method X on
a member p of the same package, defined in another file.
So don't write code like that.
Added missing test of 'definitions'.
JSON tests now sanitize absolute $GOPATH filenames in the output.

We define a derived mode of compilation-mode, so that various
names say "guru" instead of "compilation", and use the hooks it
provides to apply our postprocessing incrementally instead of
all at the end. It's much faster, and works nicely with the
new streaming referrers query.
Compilation mode requires a shell command, not an execve array,
so go-guru--compile-command joins the arguments with spaces.
go-guru--exec has been specialized for JSON mode,
and renamed to go-guru--json.
go-guru--set-scope-if-empty is now done by each mode, to avoid
the NEED-SCOPE parameter to go-guru--exec.

This CL makes little observable difference to the behavior but paves the
way for streaming 'referrers' and (later) 'implements' queries which
scan the entire workspace, but print each result as soon as it is found.
The go/loader package now exposes a hook, AfterTypeCheck, that lets
clients inspect each package as soon as it is type-checked, and also
modify it, for instance to release unneeded data structures.
A 'referrers' query applied to an exported object must scan the entire
workspace. It uses this hook so to gather uses of the query object in
streaming fashion. However, for now, it still accumulates the results
and prints them all at the end, though I propose to change that in a
follow-up.
Code details:
- The referrers logic had a 2-iteration loop to load first the query
package and then if necessary the enlarged program. The second
iteration has now been unrolled and split into globalReferrers.
- Queries for package names (whether in a package declaration or
a qualified identifier) have been split off into packageReferrers.
It now loads all direct importers of the query package,
which catches some references that were missing before.
(It used to inspect only the forward dependencies of the query
package.)
Also:
- Referrers.Pos (the position of query identifier) was removed from the
JSON output. It's a nuisance to compute now, and it's already
absent from the plain output.
(In a follow-up, I plan to simplify the information content of the
JSON output exactly what is currently printed in the plain output.)

Before, "bundle -help" printed only one not particularly useful line:
Usage of bundle:
and "bundle" printed a bit more but not a standard usage message:
bundle: Usage: bundle package dest prefix
Arguments:
package is the import path of the package to concatenate.
dest is the import path of the package in which the resulting file will reside.
prefix is the string to attach to all renamed identifiers.
And most of that output belonged in (but was missing from) the doc comment,
which leaned heavily on the reader inferring usage from one example.
While fixing all this, I ended up dropping "dest" and "prefix" as required
arguments: perfectly good defaults can be inferred in the common case
where the bundle is intended for the current directory. The defaults can be
overridden with the new -dst and -prefix option.
I corrected a TODO about not assuming the package name could be
derived from the destination import path. Like -dst and -prefix, the
default package name can be inferred from the current directory,
but there is also a new -pkg option to override the default if needed.
I added a -o option to specify the destination output file (standard output
is still the default output). One benefit of -o is that it makes the bundle
commands self-contained in the sense of not needing a shell.
That in turn makes them suitable for use with "go generate", so when -o
is specified the bundle output now includes a "//go:generate" comment
for updating the bundle mechanically.
To keep bundle working for net/http's use case, I added a -importmap
option to specify additional import rewrites (net/http needs the http2
import of golang.org/x/net/http2/hpack rewritten to begin with internal/golang.org).
The net effect of all of this is that the first two lines at the top of
net/http/h2_bundle.go will change from:
// Code generated by golang.org/x/tools/cmd/bundle command:
// $ bundle golang.org/x/net/http2 net/http http2
to
// Code generated by golang.org/x/tools/cmd/bundle.
//go:generate bundle -o h2_bundle.go -prefix http2 -import golang.org/x/net/http2/hpack=internal/golang.org/x/net/http2/hpack golang.org/x/net/http2
and net/http's copy of http2 can now be updated by "go generate"
instead of by copying and pasting commands from source code to shell.
For an experiment I am doing with cmd/dist bundling archive/zip,
the header is even shorter and makes a better demonstration of the
power of the defaults:
// Code generated by golang.org/x/tools/cmd/bundle.
//go:generate bundle -o zip.go archive/zip
New usage message, printed by "bundle -help" and "bundle":
Usage: bundle [options] <src>
-dst path
set destination import path (default taken from current directory)
-import map
rewrite import using map, of form old=new (can be repeated)
-o file
write output to file (default standard output)
-pkg name
set destination package name (default taken from current directory)
-prefix p
set bundled identifier prefix to p (default source package name + "_")
See CL for new doc comment.
Following this CL I will send a CL updating the two-line header in net/http/h2_bundle.go
to match the new usage of the bundle, whatever that ends up being.

As an optimization, the callers and callstack queries now avoid the
relatively costly pointer analysis in some common cases:
The callers of a function that is never address-taken can be enumerated
directly from the SSA representation.
Similarly, the callstack can be computed initially by ignoring dynamic
call edges; we run the pointer analysis only if no path is found in this
partial callgraph. As a bonus, this also causes the tool to
preferentially report all-static callpaths.
A callers query on fmt.Errorf now completes in 3 seconds instead of 8,
and a callstack query completes in 2 seconds instead of 8.
The new code is covered by the existing tests.

In spite of https://blog.golang.org/examples and
http://golang.org/pkg/testing/#pkg-examples, a number of internal Go
authors have found writing documentation examples to be problematic in
the sense that the syntax is error-prone due to loose coupling with
identifiers found in the source corpus.
This commit introduces a suite of validations for documentation
examples:
Overall:
- Correct suffices, if present
- Niladic function argument and return signatures
func Example() {}
func ExampleF() {}
- F exists
func ExampleT() {}
- T exists
func ExampleT_M() {}
- T exists
- M exists within T
Further, if the example is in `package foo_test`, vet attempts to
resolve the respective lookups in `package foo`, if `package foo`
exists (cf., `package stringutil_test`).

fiximports enumerates the set of packages identified by the
command-line arguments, using "go list" notation. Within each
package, it replaces all imports of non-canonical packages by their
canonical name, introducing an import renaming if (heuristically)
necessary.
If a package comes from one of the -baddomains, and it has no import
comment, fiximports reports an error. The error message includes the
list of packages that import the errant package, directly or
indirectly. This flag is used to indicate "sinking ship" package
hosting domains like code.google.com.
Caveat: this process is not trivially reversible. Consider a package A
to which we add an import comment "B", and run the tool. Package C,
which imported A, now imports B. ('go get -u' would fetch package B).
But changing the import comment in directory A and re-running the tool
will not cause C to be changed because it no longer imports A; it
imports B.

Usage:

You can also specify a number of parallel processes with -p flag;
instruct the utility to not kill hanged processes for gdb attach;
or specify the failure output you are looking for (if you want to
ignore some other episodic failures).
Do you find it useful?
