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).

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.

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

_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.

This removes much of the AST logic out of main.go,
and makes it easier to build custom vet binaries
The trade-off in this change is for flexibility.
There's very little change in the per-check files,
a lot less code in main.go (specifically the AST walking
logic has shrunk), and it makes it much easier to build
custom vet binaries simply by dropping new source files
in the directory.

If you have multiple runs in old.txt and new.txt
the default behavior is to match them up pairwise
and compare successive pairs (and if you have a
different number of runs in each file, benchcmp
refuses to do anything).
The new -best flag changes the behavior to instead
compare the fastest run of each benchmark from
the two files. This makes sense if you believe that
the fastest speed is the 'actual' speed and the slower
results are due to the computer spending time doing
non-benchmark work while the benchmark was
running.

An identifier X in anonymous struct field struct{X} is both a

Also, fix two bug related to tagless switches:
- An entry was being recorded in the Object map for a piece of

Command set:
- what: an extremely fast query that parses a single
file and returns the AST stack, package name and the
set of query modes that apply to the current selection.
Intended for GUI tools that need to grey out UI elements.
- definition: shows the definition of an identifier.
- pointsto: the PTA features of 'describe' have been split
out into their own command.
- describe: with PTA stripped out, the cost is now bounded by
type checking.
Performance:
- The importer.Config.TypeCheckFuncBodies predicate supports
setting the 'IgnoreFuncBodies' typechecker flag on a
per-package basis. This means we can load dependencies from
source more quickly if we only need exported types.
(We avoid gcimport data because it may be absent or stale.)
This also means we can run type-based queries on packages
that aren't part of the pointer analysis scope. (Yay.)
- Modes that require only type analysis of the query package
run a "what" query first, and restrict their analysis scope
to just that package and its dependencies (sans func
bodies), making them much faster.
- We call newOracle not oracle.New in Query, so that the
'needs' bitset isn't ignored (oops!). This makes the
non-PTA queries faster.
Also:
- removed vestigial timers junk.
- pos.go: existing position utilties split out into own file.

A function such as this:
func one() (x int) {
defer func() { recover() }()
x = 1
panic("return")
}
that combines named return parameters (NRPs) with deferred calls
that call recover, may return non-zero values despite the
fact it doesn't even contain a return statement. (!)
This requires a change to the SSA API: all functions'
control-flow graphs now have a second entry point, called
Recover, which is the block at which control flow resumes
after a recovered panic. The Recover block simply loads the
NRPs and returns them.
As an optimization, most functions don't need a Recover block,
so it is omitted. In fact it is only needed for functions that
have NRPs and defer a call to another function that _may_ call
recover.
Dataflow analysis of SSA now requires extra work, since every
may-panic instruction has an implicit control-flow edge to
the Recover block. The only dataflow analysis so far implemented
is SSA renaming, for which we make the following simplifying
assumption: the Recover block only loads the NRPs and returns.
This means we don't really need to analyze it, we can just
skip the "lifting" of such NRPs. We also special-case the Recover
block in the dominance computation.
Rejected alternative approaches:
- Specifying a Recover block for every defer instruction (like a
traditional exception handler).
This seemed like excessive generality, since Go programs
only need the same degenerate form of Recover block.
- Adding an instruction to set the Recover block immediately
after the named return values are set up, so that dominance
can be computed without special-casing.
This didn't seem worth the effort.
Interpreter:
- This CL completely reimplements the panic/recover/
defer logic in the interpreter. It's clearer and simpler
and closer to the model in the spec.
- Some runtime panic messages have been changed to be closer
to gc's, since tests depend on it.
- The interpreter now requires that the runtime.runtimeError
type be part of the SSA program. This requires that clients
import this package prior to invoking the interpreter.
This in turn requires (Importer).ImportPackage(path string),
which this CL adds.
- All $GOROOT/test/recover{,1,2,3}.go tests are now passing.
NB, the bug described in coverage.go (defer/recover in a concatenated
init function) remains. Will be fixed in a follow-up.

+ test.
Also:
- provide non-nil map to Importer.doImport0() to avoid a crash.
- reorganize oracle "needs" bits.
- reduce "needs" of 'freevars' and 'implements' queries by avoiding
ssa.Packages when types.Package suffices.

Motivation: pointer analysis tools (like the oracle) want the
user to specify a set of initial packages, like 'go test'.
This change enables the user to specify a set of packages on
the command line using importer.LoadInitialPackages(args).
Each argument is interpreted as either:
- a comma-separated list of *.go source files together
comprising one non-importable ad-hoc package.
e.g. "src/pkg/net/http/triv.go" gives us [main].
- an import path, denoting both the imported package
and its non-importable external test package, if any.
e.g. "fmt" gives us [fmt, fmt_test].
Current type-checker limitations mean that only the first
import path may contribute tests: multiple packages augmented
by *_test.go files could create import cycles, which 'go test'
avoids by building a separate executable for each one.
That approach is less attractive for static analysis.
Details: (many files touched, but importer.go is the crux)
importer:
- PackageInfo.Importable boolean indicates whether
package is importable.
- un-expose Importer.Packages; expose AllPackages() instead.
- CreatePackageFromArgs has become LoadInitialPackages.
- imports() moved to util.go, renamed importsOf().
- InitialPackagesUsage usage message exported to clients.
- the package name for ad-hoc packages now comes from the
'package' decl, not "main".
ssa.Program:
- added CreatePackages() method
- PackagesByPath un-exposed, renamed 'imported'.
- expose AllPackages and ImportedPackage accessors.
oracle:
- describe: explain and workaround a go/types bug.
Misc:
- Removed various unnecessary error.Error() calls in Printf args.

The previous notation (sans '#') now yields an error but is
"reserved for future use", e.g. to denote line/column offsets.
Will implement as needed.

1. ParseFiles (in util.go) parses each file in its own goroutine.
2. (*Importer).LoadPackage asynchronously prefetches the
import graph by scanning the imports of each loaded package
and calling LoadPackage on each one.
LoadPackage is now thread-safe and idempotent: it uses a
condition variable per package; the first goroutine to
request a package becomes responsible for loading it and
broadcasts to the others (waiting) when it becomes ready.
ssadump runs 34% faster when loading the oracle.
Also, refactorings:
- delete SourceLoader mechanism; just expose go/build.Context directly.
- CreateSourcePackage now also returns an error directly,
rather than via PackageInfo.Err, since every client wants that.

1. call display-buffer after the postprocessing step to avoid display glitch.
2. suppress the postprocessing progress message---it's too verbose.
(instead I should just make the postprocessing loop faster)
Also: rename channel-peers to just peers for consistency with other commands and documentation.

See json.go for interface specification.
Example usage:
% oracle -format=json -mode=callgraph code.google.com/p/go.tools/cmd/oracle
+ Tests, based on (small) golden files.
Overview:
Each <query>Result structure has been "lowered" so that all
but the most trivial logic in each display() function has
been moved to the main query.
Each one now has a toJSON method that populates a json.Result
struct. Though the <query>Result structs are similar to the
correponding JSON protocol, they're not close enough to be
used directly; for example, the former contain richer
semantic entities (token.Pos, ast.Expr, ssa.Value,
pointer.Pointer, etc) whereas JSON contains only their
printed forms using Go basic types.
The choices of what levels of abstractions the two sets of
structs should have is somewhat arbitrary. We may want
richer information in the JSON output in future.
Details:
- oracle.Main has been split into oracle.Query() and the
printing of the oracle.Result.
- the display() method no longer needs an *oracle param, only
a print function.
- callees: sort the result for determinism.
- callees: compute the union across all contexts.
- callers: sort the results for determinism.
- describe(package): fixed a bug in the predicate for method
accessibility: an unexported method defined in pkg A may
belong to a type defined in package B (via
embedding/promotion) and may thus be accessible to A. New
accessibleMethods() utility fixes this.
- describe(type): filter methods by accessibility.
- added tests of 'callgraph'.
- pointer: eliminated the 'caller CallGraphNode' parameter from
pointer.Context.Call callback since it was redundant w.r.t
site.Caller().
- added warning if CGO_ENABLED is unset.

Pro: no shell quotation needed.
Con: can't be parsed by (the perpetually useless) Scanf.

Update golang/go#6212
See issue 6259.
When that is resolved, we can do a better job. Until then, we just see if the
type has a method called Format and, if so, assume it's a Formatter and so
there's nothing to check.

+ Emacs integration.
+ Emacs integration test.
+ very rudimentary Vim integration. Needs some love from a Vim user.
TODO (in follow-ups):
- More tests would be good.
We'll need to make the output order deterministic in more places.
- Documentation.

App Engine needs the whitelist file and it's cleaner if it's
in its own package where it can be imported directly, without
pushing composite.go through a pile of sed.
