22ede605a7 go.tools/cmd/stringer: use const for names, slice for map strings
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.
Also change the generate map code go use a single sliced string, to reduce the
size of the compiled representation (only one string value).

2c5c896732 go.tools/cmd/stringer: new tool
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.

5dca7d8bd1 go.tools/go/types: LookupFieldOrMethod checks method set
LookupFieldOrMethod now also decides whether a found
method is actually in the method set. Simplifies call
sites. Added corresponding API tests.

TODO (separate CL): Decide what the correct value for
the indirect result should be (as required for code
generation). For now, the result value for indirect
is unchanged from before if a field/method is found.

ba91af23b8 cmd/cover: add start lines numbers to each function in -func mode
This CL aims to fix the problem described here:

https://groups.google.com/forum/#!topic/golang-nuts/R6ms1n9KjiY

This makes it easier to parse via external tools such as editors. Editors can
show each function in a list and jump directly to each function with this
additional information. This pattern can be seen in other Go tools such as "go
test" in the form of:

--- FAIL: TestCover (0.52 seconds)

f11381f265 go.tools/cmd/cover: don't assume code is gofmt'd
We want to make an if look like two blocks and have the coverage
report for the else block decorate the "else" keyword with the right
color. To do this, we adjust the apparent starting point of the else
block to include the "else".

The previous code assumed the way to do this was to move the
width of "else " backwards from the else block's opening brace, but
that assumes there is a space there. Instead, we now just start the
else block exactly at the end of the if block. Simpler, cleaner, and
fixes a bug.

Fixes golang/go#8557.

7da5f193b7 go.tools/cmd/vet: detect stupid boolean conditions
This CL introduces two vet checks. Statistics and code below are from a recent 50mb corpus of public code.

1. Check for redundant conjunctions and disjunctions. This check caught 26 instances, of which 20 were clearly copy/paste bugs and 6 appeared to be mere duplication. A typical example:

if xResolution < 0 || xResolution < 0 {
        panic("SetSize(): width < 0 || height < 0")
}

2. Check for expressions of the form 'x != c1 || x != c2' or 'x == c1 && x == c2', with c1 and c2 constant expressions. This check caught 16 instances, of which all were bugs. A typical example:

if rf.uri.Scheme != "http" || rf.uri.Scheme != "ftp" {
        rf.uri.Scheme = "file"
}

Fixes golang/go#7622.

Previously you would need to (unintuitively) set the -http flag to
achieve this.

In package godoc, set up the FS tree before loading the index, and
then return before starting the index refresh loop. Previously the
index would be loaded and then immediately refreshed, negating the
benefits of the on-disk index.

f895b43688 vet: Rearrange checkers to use a registration system.
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.

222283a9c8 go.tools/cmd/benchcmp: add -best flag
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.
