This means that running stringer should always
have the intended effect, without having to
go install the package first, which was a common
source of confusion.
The source importer is marginally slower,
but stringer is run infrequently,
and we're only typechecking one package (and fmt),
not an entire tree, as vet does.

The GOPATH environment variable is defined at

It is legal for Go packages to be in any of those places, not only
the first entry. Look in all places for golang.org/x/tools repository.
Cache the directory that is found. It's slightly more expensive
to look for it, since potentially multiple directories must be

The go1.9 type checker now returns fake packages in addition to an
error if the package was not found at all. This changes the behavior
of guru in a release-specific way, requiring the test to be split into
a common part and a go1.9-specific part.
In hindsight, perhaps it would have been better to place the
expectation in a comment alongside the query so that they can be
easily enabled or disabled together. (The downside of that design is
that you can't batch-update all the expectations to match the actual
behavior.)

Prior to this change, handlerServer.GetPageInfo created a build.Context
starting with build.Default, and provided custom implementations for
its IsAbsPath, ReadDir, and OpenFile funcs. Those funcs would operate
on h.c.fs virtual filesystem.
https://godoc.org/go/build#Context.IsDir is documented as:
// IsDir reports whether the path names a directory.
// If IsDir is nil, Import calls os.Stat and uses the result's IsDir method.
IsDir func(path string) bool
IsDir was left as nil, and so the default implementation was used.
The default implementation uses os.Stat and isn't aware of the h.c.fs
virtual filesystem.
This appears to have been harmless in the past, but after the change to
go/build in https://golang.org/cl/33158, it started to interfere with
the operation of godoc. The command godoc began to fail to resolve
relative import path "." in directories that exist, because the
incorrect IsDir implementation was looking in real filesystem, rather
than the virtual one:
$ ./godoc fmt
2017/03/04 18:59:50 cannot find package "." in:
/target
$ ./godoc -http=localhost:6060
2017/03/04 19:00:07 cannot find package "." in:
/src/fmt
Providing a custom implementation of IsDir that is aware of the h.c.fs
virtual filesystem, and performs a stat operation on the correct path
there resolves that problem. It also fixes the failing tests.
Additionally, because the exact error string returned from
Context.Import has changed after https://golang.org/cl/33158,
and now contains the text "package not found" rather than the
underlying error text from filesystem caused by a failed ReadDir
operation, the expected error message from "./godoc nonexistingpkg"
in a test needed to be updated to "cannot find package". It's no longer
dependent on the operating system.
It might be desirable to provide more relevant detail in the error
message from cmd/godoc when a package is not found, but that should be
determined and done in a followup CL. The scope of this one is to fix
normal functionality.
This change follows update to go/build in https://golang.org/cl/33158.

This change primarily exists to import Typescript and the
ES6 module loader polyfill as dependencies for this project.
Both dependencies are relatively lightweight and can be easily
removed if we decide we don't need them.
The module loader polyfill implements support for an upcoming
browser feature in ES6 (the next version of JavaScript). This
feature helps modularize Javascript code and conveniently split it
into multiple files. It should be supported by the stable versions
of the four major browsers (Chrome, Firefox, Safari and Edge)
by the end of the year. Once that happens, we can remove the polyfill.
The Typescript compiler provides two things: First, it compiles
new, but not-yet-supported ES6 Javascript features into ES5. It
also provides a typechecker similar to what Closure does, but types
are indicated in syntax rather than JSDoc comments. If we decide
we don't want this dependency, we can compile the Typescript code
into human-readable JavaScript code. (The compiler basically
strips out types and replaces ES6 language features with more
well-supported JavaScript equivalents). The Typescript compiler
is not required for development. typescript.js and a feature in
the module loader will be used to compile Typescript into JavaScript
at serving time. (We might want to do something different for the
production version, but we can get to that later).
The change also adds code to serve the HTML and Javascript files.

Instead, this CL introduces a new (private) filepath.Walk

In addition to avoid an Lstat per file, it also reads directories
concurrently. The old goimports code did that too, but now that logic
is removed from goimports and the code is simplified.

I felt the burn of my laptop on my legs, spinning away while processing
goimports, and felt that it was time to make goimports great again.
Over the past few years goimports fell into a slow state of disrepair
with too many feature additions and no attention to the performance
death by a thousand cuts. This was particularly terrible on OS X with
its lackluster filesystem buffering.
This CL makes goimports stronger, together with various optimizations
and more visibility into what goimports is doing.
* adds more internal documentation
* avoids scanning $GOPATH for answers when running goimports on a file
under $GOROOT (for Go core hackers)
* don't read all $GOROOT & $GOPATH directories' Go code looking for
their package names until much later. Require the package name of
missing imports to be present in the last two directory path
components. Then only try importing them in order from best to
worst (shortest to longest, as before), so we can stop early.
* when adding imports, add names to imports when the imported package name
doesn't match the baes of its import path. For example:
import foo "example.net/foo/v1"
* don't read all *.go files in a package directory once the first file
in a directory has revealed itself to be a package we're not looking
for. For example, if we're looking for the right "client" for "client.Foo",
we used to consider a directory "bar/client" as a candidate and read
all 50 of its *.go files instead of stopping after its first *.go
file had a "package main" line.
* add some fast paths to remove allocations
* add some fast paths to remove disk I/O when looking up the base
package name of a standard library import (of existing imports in a
file, which are very common)
* adds a special case for import "C", to avoid some disk I/O.
* add a -verbose flag to goimports for debugging
On my Mac laptop with a huge $GOPATH, with a test file like:
package foo
import (
"fmt"
"net/http"
)
/*
*/
import "C"
var _ = cloudbilling.New
var _ = http.NewRequest
var _ = client.New
... this took like 10 seconds before, and now 1.3 seconds. (Still

For a 'definition' query on X in p.X, use special logic to load and

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.

go-guru-hl-identifier, which will highlight all instances of the
identifier under point, or they can enable the
go-guru-hl-identifier-mode minor mode. The minor mode sets up an idle
timer, which will highlight the current identifier after a configurable
timeout. If the user modifies the buffer, or moves point off of an
identifier, we clear the highlight.

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.)

A consequence of CL 19747 was that ad hoc packages of a single filename
are no longer valid -scope arguments, which broke most of the tests.
This CL fixes the tests by extracting the import path from the filename.
The test output now includes the import path, not the package
name, of each of these packages, so the output was updated too.
Also, the -scope argument caused the main package to be imported twice,
once as main.go and once under its import path, causing duplicate
'implements' results.
I'm not sure how I failed to notice this.

Editor modes that invoke the goimports command on temporary copies

$ GOPATH= goimports < x.go

$ GOPATH= goimports -srcdir $GOROOT/src/math x.go

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.
