3e7aa9e599 godoc: generate TOC from server-side for search page
Currently, we generate the TOC for a page dynamically after page load
through javascript. This is fine for pages with static content.

But for pages with dynamic output like /search, sometimes this causes a
noticeable page jump due to extensive DOM traversal. Also, the heuristics
to calculate the no. of columns is very rudimentary and fills the entire
above-the-fold area if the no. of results is very large.

Therefore, we generate the TOC from server side itself. And improve
the no. of columns heuristic further to accomodate up to 4 columns.

This improves page performance and utilizes real estate appropriately
according to the input.

Some screenshots at laptop (1366x768) resolution.

9545aa7b51 go/analysis/cmd/vet: new name for cmd/analyze
This is the new vet command. It can be run standalone:

	$ vet my/project/...

or (soon) under go vet:

	$ GOVETTOOL=$(which vet) go vet my/project/...

A forthcoming CL will add support for the second mode, and define a
vet-lite command that supports only that mode, but has fewer
dependencies; it is intended to be vendored into $GOROOT/src/cmd/vet.

a019f6b7c5 go/analysis/internal/analysisflags: common flag handling
The analysisflags package provides a function to help
ensure that all drivers support consistent command-line
interfaces.  In particular, -analyzer.enable flags use
tristate logic as in vet, and the -flags flag dumps
a list of flags in JSON for use by 'go vet' and other
build systems.

This code is in a separate package from internal/checker
(the common parts of multichecker, singlechecker)
because we don't want the forthcoming vet-lite (formerly
known as doctor) driver to have an unnecessary dependency
on go/packages.  (When go/packages is promoted to the
standard library we can consolidate them.)

+ Test of tristate analyzer selection logic.

6adeb8aab2 go/analysis/passes/nilness: degenerate nil condition checker

	p := &v

	if p != nil { // tautological condition
	}

and:

	if p == nil {
		print(*p) // nil dereference
	}

(It was originally developed within Google's Go analysis framework and
can now be published in a form useful to all analysis drivers.)

This CL also includes buildssa, an Analyzer that constructs SSA for
later analysis passes but does not report diagnostics or facts of its
own.

63d31665e3 go/packages: add name= query
Add an implementation of name= for go list. It will be used to
implement goimports and godoc-like lookups by package name.

Imported a copy of the semver package from the stdlib to do version
comparison, and tweaked the gopathwalk API to include a hint about what
kind of source directory is being traversed.

Note that the tests, despite my best efforts, are not hermetic: go list
insists on doing version lookups in situations where it seems to me like
it shouldn't need to.

I think this implementation is ready for serious use. The one thing I'm
nervous about is that it currently does a substring match when looking
for a package name, so if you look up a package named "a" you will get
a huge number of results. This matches goimports' behavior but I don't
know if it's suitable for general use.

3a0c4deef1 go/analysis/passes/printf: changes for analysis API
Guide to changes:

- The -printfuncs flag is renamed -printf.funcs.
  It no longer supports "pkg.T.f" form, requiring instead
  "(dir/pkg.T).f" or "(*dir/pkg.T).f".
  The legacy ":%d" suffix is no longer supported.

- (*testing.T).Errorf and friends are removed from the isPrint map
  because they are discovered by induction while analyzing package
  "testing".

- localPrintfLike map operations are replaced by the Fact mechanism.

- The go/types representation is used instead of strings/ast.Nodes in
  various places. For example:

       pkgpath, name string -> *types.Func  (to identify a function)
    format, args *ast.Field -> *types.Var   (to identify format/args params)

  This was required to fix a latent bug in maybePrintfWrapper's
  handling of format string parameters` declared using "factored"
  syntax, such as: func f(foo, format string, args...interface{}).
  See L253 of the original testdata file for a testcase that ensured
  the buggy (?) behavior.

- func printfLike is removed as it was deadcode.

- isFormatter is rewritten to avoid a global variable.

- "if verbose { warn }" is replaced by "if false { report }" for now.

- recursive stringer is rewritten more simply in term of go/types.

If the program has tests,
the last message is "All tests passed" in case of success.
Otherwise it is "N tests failed".

If the program has exited with non-zero code,
the exit message is postfixed with the code.

This CL adds output for timed out programs.

This CL is prerequisite for the backend change in CL 141478.

The inline playground had a fixed width due to which it gets partially

Also, since the playground appears on top of the button, there is
no way to hide it except to reload the page. So, added a click handler

8919434dde go/analysis/passes/copylock: add workaround for go1.10
CL 121876 made sync.noCopy implement sync.Locker and
added this as an assumption to vet.  But now that copylock
is no longer in the standard library it cannot
assume that it is analyzing a recent standard library
in which noCopy has an Unlock method.

aa46a01996 go/ssa/ssautil: add AllPackages method
In go1.10, go/packages falls back to loading all packages
from source but not typechecking function bodies for imports.
The ssautil.Packages function would nonetheless provide
the partially-typed ASTs to the SSA builder, which would crash.
Now Packages only passes syntax trees to the SSA builder for
the initial packages, which are the only ones guaranteed to be
fully typed.

It is impossible to discern whether the caller of Packages intends to
build SSA code for dependencies, as in some clients such as
cmd/callgraph, so we add a new function, AllPackages, that expresses
this intent.

Fixes golang/go#28106

13ebad898d go/packages: use "=" instead of ":" for special queries
This change updates the language accepted through the arguments
to packages.Load to make it more consistent. There are now two layers.
A pattern containing an "=" is considered to be a special query, and the
part of the pattern up to the first "=" is considered the query type. All
other patterns are to be interpreted as the build system interprets it.
For now two special queries exist. file= has the behavior that contains:
did: finding packages containing the given file. The query type pattern=
is used to pass through a pattern to be interpreted by the build system.
pattern= is a type of escaping to allow passing through patterns that
contain an "=" to be interpreted by the underlying buildsystem. To allow
for new query types to be introduced, packages.Load will report an
error if the qury type is not understood. We expect name= to be added in
an  upcoming change.

"contains:" changes to "file=". A new

d1d6d0cbb6 imports: refactor tests
We plan to change goimports to use go/packages, which requires changing
its internal design. Having tests use the external interface makes those
changes easier. After this change almost all testing is through Process.

Broadly speaking, the changes are:

- Switch to subtests wherever possible. This involved making up many
names, which I hope are accurate.

- Convert tests that used findImport directly to use Process instead.
This often made them slightly larger but not unduly IMO.

- Replace simple tests with entries in the giant table at the top.

- Remove uses of custom goroots, which are troublesome for
go/packages' use of the go command. Almost none of them were actually
necessary. I left one in TestGoRootPrefixOfGoPath; I'm not sure how
to handle it yet.

19e2aca3fd internal/gopathwalk: create
Extract goimports' logic for walking Go source directories into a
separate package, suitable for use in go/packages. No functional
changes. Added a convenience feature to fastwalk, allowing the user to
say that they're done with a directory and stop receiving callbacks for
it.

Testing is a little light; I expect goimports' tests to cover most
everything we care about.

1d07bcb7f9 imports: refactor directory walking
We plan to reuse goimports' directory walking logic in the
implementation of go/packages. To prepare for that, refactor it to have
fewer global variables and a simpler interface.

This CL makes no functional changes, but may change performance
slightly. It always scans both $GOPATH and $GOROOT, and does so
serially. I expect that fastwalk's internal parallelism is enough to
keep the disk busy, and I don't think it's worth optimizing for people
hacking on Go itself.

87312bc3ed go/packages: use effective GOARCH to determine type size function
The typechecker's Sizes function is not currently set correctly.
The correct answer requires information known only to the build
system's query tool (go list, blaze query, etc), and we need to
add a mechanism for it to return this information.

In the meantime, we use this simple workaround: if the GOARCH
environment variable is set, we use that to determine sizes according
to the conventions of gc. Otherwise, we use the architecture for which
the application was compiled. Both could easily be incorrect, but this
is nonetheless progress.

This change should fix the tests of go/analysis/passes/shift,
which are currently broken for GOARCH=386 because the analysistest
driver uses go/packages, which ignores GOARCH.
