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

Previously, gorename rejected all method renamings if it would
change the assignability relation.
Now, so long as the renaming was initiated at an abstract
method, the renaming proceeds, changing concrete methods (and
possibly other abstract methods) as needed. The user
intention is clear.
The intention of a renaming initiated at a concrete method is
less clear, so we still reject it if it would change the
assignability relation. The diagnostic advises the user to
rename the abstract method if that was the intention.
Additional safety checks are required: for each
satisfy.Constraint that couples a concrete type C and an
interface type I, we must treat it just like a set of implicit
selections C.f, one per abstract method f of I, and ensure the
selections' meanings are unchanged.
The satisfy package no longer canonicalizes types, since this
substitutes one interface for another (equivalent) one, which
is sound, but makes the type names random and the error
messages confusing.
Also, fixed a bug in 'satisfy' relating to map keys.

In this code, for example,

the two referring Idents x appear at the same lexical depth,
inside the function f's Scope object, yet they resolve to
different objects.
This package associates a lexical.Environment instance with
every reference to capture these differences. Each
environment is a linked list of enclosing Blocks, and for each
block, a number indicating what prefix of its bindings are
visible. (Zero for the first 'x' reference above, 1 for the
second.)
