340a1cdb50 internal/lsp: copy fact support from go/analysis/internal/checker.go
This changes the analysis code from that which was in unitchecker.go
to that in checker.go, so we can run actions that get facts for dependencies
concurrently.

Adds the rest of the traditional vet suite to the LSP.

TODO(matloob): test that facts are actually propagated between packages

44bee7e801 internal/lsp: changing server noun to serve verb
Also adding in --remote support and using it to implement the equivalent
functionality of the external forward command
Also adding in --listen as a replacement for --port as it is more flexible,
specifically it allows localhost:port which
is helpful in environments where opening remotely accesible ports is
problematic.

This starts hooking up the analysis framework into the LSP. It runs

no parse or typecheck failures.

8dbcc66f33 go/analysis/passes/atomicalign: handle pointers to struct
The atomicalign checker detects non-64-bit aligned struct field
arguments to sync/atomic functions but currently misses out cases
where the struct variable identifier is a pointer to struct. This
is very common as it happens when the 64-bit field is accessed
in a method with pointer receiver, where the struct is itself the
method receiver. Add some tests to cover that new case.

While I'm at it, fix some typos.

0a99049195 go/vcs: remove go.googlesource.com vcsPath entry
This change synchronizes the absence of a special case entry for
go.googlesource.com import paths in cmd/go/internal/get to this

but it was never added to cmd/go/internal/get itself.

Having an go.googlesource.com entry here but not in cmd/go/internal/get
means the import path resolution logic diverges from that of the go
command, which is counter to the goal of this package.

After this change is applied, vcs.RepoRootForImportPathStatic reports
correct results for import paths like "go.googlesource.com/scratch.git"
(resolving it without an error) and "go.googlesource.com/scratch"
(reporting an error).

4e3518700c go/packages: stop parsing files if the context is canceled
`stamblerre/gocode`, which is the fork of `mdempsky/gocode` that supports Go 1.11 modules, uses `packages.Load` to load all of the Go code for, among other things, IDE autocomplete support.  A common aspect to IDE autocomplete is asking for suggestions very frequently (perhaps at every character typed).  Once the user has typed another character, the previous request for autocomplete is invalid and can be canceled.

`packages.Load` already stops its `go list` component if the context is canceled, but if the context is canceled afterward, then it will parse all of the files that it found.  This change stops the parsing of Go files once it detects that the context has been canceled.  When a file has not been processed due to cancelation, its error will be set to that of the context.

This change dramatically improves the performance of the `stamblerre/gocode` fork when requests have been canceled.

85a87a81a9 cmd/present: fix CSS when printing slides
The existing CSS style was causing slides to not align with page
boundaries when printing slides. The cause of that is the CSS transform
property that is applied to automatically scale size of slides.
This change clears the transform property just before printing.

9279ec27fd cmd/tip: also fetch x/net repository before building cmd/godoc
x/tools/cmd/godoc uses at least one Go package from x/net as of
CL 157197.

Don't add it to signature because we don't want the signature to
change whenever new commits to x/net are pushed, causing tip.golang.org
to be redeployed. This is because x/net is not considered a critical
component of the website at this time, and that's not expected to
change soon.

When the website begins using modules, it will specify the x/net
version precisely and this decision will no longer matter.

9c309ee22f imports: stop using go/packages for modules
go/packages needs to call `go list` multiple times, which causes
redundant work and slows down goimports. If we reimplement `go list` in
memory, we can reuse state, saving time. `go list` also does work we
don't really need, like adding stuff to go.mod, and skipping that saves
more time.

We start with `go list -m`, which does MVS and such. The remaining work
is mostly mapping import paths and directories through the in-scope
modules to make sure we're giving the right answers. Unfortunately this
is quite subtle, and I don't know where all the traps are. I did my
best.

cmd/go already has tests for `go list`, of course, and packagestest is
not well suited to tests of this complexity. So I ripped off the script
tests in cmd/go that seemed relevant and made sure that our logic
returns the right stuff in each case. I'm sure that there are more cases
to cover, but this hit all the stuff I knew about and quite a bit I
didn't.

Since we may want to use the go/packages code path in the future, e.g.
for Bazel, I left that in place. It won't be used unless the magic env
var is set.

Files in internal and imports/testdata/mod were copied verbatim from
cmd/go.

24cd39ecf7 go/analysis/passes/atomicalign: add atomicalign ckecker
The atomicalign Analyzer checks the alignment of 64-bits variables
accessed atomically via sync/atomic functions on 32-bits
architectures. Per the sync/atomic BUG note those variables must
be 64-bits aligned, otherwise a runtime panic is issued.

The analyzer only shows and runs on 32-bits architectures.

This CL should not introduce any false positives.

Add some tests in testdata/src/a to verify the analyzer behavior
on affected architectures plus some very basic test to verify that
no warning is generated on non-affected ones.

16909d206f imports: remove globals, stop using build.Default
The imports package's public API is build.Default, but that doesn't mean
we need to use it in the internal implementation or the tests. Now we
have a new type, fixEnv, that contains everything relevant from
build.Context, as well as the various global vars that were only used
for testing.

Don't worry too much about the new function parameters; they mostly
move into the resolvers in the next CL.

Refactoring only; no user-visible changes intended.

6466e7265e imports: don't eagerly guess package names
Before this change, we guessed package names during loadPackageNames
when necessary. That made it impossible to tell if we failed to load
a package's name, e.g. because its source code is unavailable. That
interferes with fixes for golang/go#29557. It also meant that each
implementation of package name loading needs to do the guessing,
which gets annoying in CL 158097.

Instead, leave package names unset unless we're certain about them, and
guess only in (*pass).importIdentifier when necessary.

This in turn requires go/packages to retain and expose the type sizing
