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.

Features:
More robust: silently ignore type errors in modes that don't need
SSA form: describe, referrers, implements, freevars, description.
This makes the tool much more robust for everyday queries.
Less configuration: don't require a scope argument for all queries.
Only queries that do pointer analysis need it.
For the rest, the initial position is enough for
importQueryPackage to deduce the scope.
It now works for queries in GoFiles, TestGoFiles, or XTestGoFiles.
(It no longer works for ad-hoc main packages like
$GOROOT/src/net/http/triv.go)
More complete: "referrers" computes the scope automatically by
scanning the import graph of the entire workspace, using gorename's
refactor/importgraph package. This requires two passes at loading.
Faster: simplified start-up logic avoids unnecessary package loading
and SSA construction (a consequence of bad abstraction) in many
cases.
"callgraph": remove it. Unlike all the other commands it isn't
related to the current selection, and we have
golang.org/x/tools/cmdcallgraph now.
Internals:
Drop support for long-running clients (i.e., Pythia), since
godoc -analysis supports all the same features except "pointsto",
and precomputes all the results so latency is much lower.
Get rid of various unhelpful abstractions introduced to support
long-running clients. Expand out the set-up logic for each
subcommand. This is simpler, easier to read, and gives us more
control, at a small cost in duplication---the familiar story of
abstractions.
Discard PTA warnings. We weren't showing them (nor should we).
Split tests into separate directories (so that importgraph works).

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.
+ Lots more tests.

"static" ignores dynamic calls altogether.
"cha" uses Class Hierarchy Analysis, which assumes that a
dynamic call may dispatch to any func or method that satisfies
the type.
Both these algorithms can work on partial programs,
e.g. libraries without a main function or tests.
(This feature was requested after my talk last night.)

Add tests for recently introduced asm error checks in vet.
This adds tests for the new warnings about functions that
don't store to their return slot before returning or that
store to SP-relative addresses in or beyond the argument
frame. It also adds a test for leaf function handling on arm,
where the link register is not implicitly saved.

Fixesgolang/go#8792.
This is a simple change that fixes the issue. It may be desireable
to opt for a larger code change that makes this problem less likely
to be inadvertedly reintroduced in the future. For instance, a vetMain()
func can be used similar to gofmtMain(), or the os.Exit call can be
deferred.

See the usage message in main.go for orientation.
To the best of my knowledge, the tool implements all required
soundness checks, except:
- the dynamic behaviour of reflection is obviously undecidable.
- it rejects method renamings that change the "implements" relation.
It should probably be more aggressive.
- actually it only checks the part of the "implements" relation
needed for compilation. Understanding the dynamic behaviour
of interfaces is obviously undecidable.
- a couple of minor gaps are indicated by TODO comments.
Also:
- Emacs integration.
- tests of all safety checks and (some) successful rewrites.

To avoid breaking URLs, we redirect /src/pkg/* to /src/*.
The URL /pkg is now the "directory" /src, which triggers the
"Packages" index.
All other references to "src/pkg" are now gone,
except a number in the namespace documentation which are
probably still illustrative.
Tested: go test cmd/godoc godoc

Improve the generated code by using a const instead of a var for the names string.
This requires some refactoring to get neat const() and var() blocks.

This tool creates String methods from constant definitions.
It's a time-saver designed to be used from go generate.
The methods generated are efficient, more so than one
is likely to create by hand.
Given
package date
type Day int
const (
Monday Day = iota
Tuesday
Wednesday
Thursday
Friday
Saturday
Sunday
)
the command
stringer -type Day
will create the file day_string.go containing
package date
import "fmt"
var (
_Day_indexes = []uint8{6, 13, 22, 30, 36, 44, 50}
_Day_names = "MondayTuesdayWednesdayThursdayFridaySaturdaySunday"
)
func (i Day) String() string {
if i < 0 || i >= Day(len(_Day_indexes)) {
return fmt.Sprintf("Day(%d)", i)
}
hi := _Day_indexes[i]
lo := uint8(0)
if i > 0 {
lo = _Day_indexes[i-1]
}
return _Day_names[lo:hi]
}
There are several strategies for the created method chosen according to
the structure of the sequence of constants.
Handles integer types only, both signed and unsigned. That's probably
all that is needed.
Tests to follow, but the test structure will be large so sending this out
separately. The code has been heavily hand-tested but there are
some bugs. Don't depend on this until the tests are installed.
