2f84ea8ef8 cmd/godoc: move regression tests to a go test
Run them separately from the other tests in godoc_test by requiring a
regtest.host flag and by filtering on the test name.

390954b1ab cmd/godoc: re-enable host checking, allow test versions
test.golang.org is no longer -- instead allow access to version-specific
App Engine URLs (like 20181002t1342-dot-golang-org.appspot.com).

App Engine Flex uses the X-Forwarded-Proto to signify the proto used by
the originating request (it always uses h1 on 8080 when proxying the
request).

ee6b03148c godoc: migrate to App Engine flexible
See bug for more details on exactly what was migrated.

Notably:
* No more Google-internal deployment scripts; see README.godoc-app and
  the Makefile for details.
* Build tag "golangorg" is used for the godoc configuration used for
  golang.org.
* Use of App Engine libraries replaced with GCP client libraries.
* Redis is used to replace App Engine memcache.
* Google analytics is controlled by an environment variable.
* Regression tests have been migrated from Google-internal.
* hg -> git hash map is moved from Google-internal.

e9ca907325 cmd/godoc: simplify dev and prod environment for App Engine
Remove all of the code generation and the concept of "APPDIR" - just
generate godoc.zip and index files in the app directory.

Simplify generation of the zip - use a symlink so that every file in
godoc.zip is under the "goroot" directory, regardless of the
environment. Previously, the prefix would be dependent on the location
of the user's GOROOT.

Running the setup script is now optional - it's now possible to run
dev_appserver.py on a regular checkout of cmd/godoc without godoc.zip
and search index files. Use environment variables to switch whether the
zip file is used vs reading GOROOT from the filesystem.

0aa4b8830f go/packages: remove the Config.Error hook
Errors relating to a particular package (as opposed to the Load
operation as a whole) are now only recorded in the Errors
field of the corresponding Package.
Clients are responsible for printing or otherwise handling errors.
This is a breaking API change.

The PrintErrors function prints all accumulated errors,
dependencies first, and is provided for convenience.

PrintErrors is based on Visit, another helper function, which
visits each Package in an import graph.

Also:
- add an Example documenting typical use.
- update clients to handle errors explicitly.

Depends on https://go-review.googlesource.com/c/tools/+/130576

ba93f9405e godoc: update to use new goroot finding logic
The logic to determine whether a filesystem root was in GOROOT or GOPATH
still relied on runtime.GOROOT(), whereas cmd/godoc was updated to copy
the goroot finding logic from standard library.

Hence, godoc is unable to determine if a filesystem is in GOROOT or not
when the binary is outside runtime.GOROOT(). So we expose a new variable
and set that from cmd/godoc to avoid copying the logic again for the 3rd time.

9de1900191 go/packages: opt: ignore function bodies in non-initial packages
This saves 35% of wall time in a command such as

 $ gopackages -mode=syntax golang.org/x/tools/go/packages/gopackages fmt

that would otherwise typecheck every function in each package that
depends on fmt. It also applies in -mode=types when source was loaded
as a fall back for missing export data due to an error in a lower package.

Also, remove Config.TypeChecker field now that not a single of its
subfields is passed through go/packages to the type checker.
(The Sizes function is logically a result, not an input, of loading,
though we have yet to implement it properly.)

27709f6afe cmd/ssadump: use go/packages
Unlike go/loader's FromArgs, go/packages doesn't return the
non-package arguments, so we add a new repeated flag -arg=x -arg=y to
specify them.

Because we cannot add packages to a packages.Load query, we emit an
error if -run is specified and "runtime" is not among the
dependencies.

There is no easy way to distinguish synthetic test main packages
from regular main packages, so we no longer try.
This makes -test and -run orthogonal.

setting GOROOT explicitly (will fix subcommands)
and by invoking the go command to learn about
packages instead of assuming go/build has any
idea what it's doing.

Because go/packages presents each synthesized test main package
as a first-class package, the tests now analyze all of the dependencies

slower and the resulting call graph much larger,
so they now look for a subset match, not an exact match,
on the set of graph edges.

The test was looking for strings found in specific Go versions
without checking for the actual Go version running the test.

Used ReleaseTags to check whether the current go version should

P.S. The version info is inferred from the binary running the test.
But the test builds godoc using the "go" binary in $PATH. In case
one is testing different go versions, please ensure to run tests
by changing the $PATH variable to point to different go versions,
rather than using a custom go binary in a different path.

57f659e14d godoc: show version information for stdlib
This change reads $GOROOT/api/go1.*.txt when godoc starts and caches
information about which versions of Go introduce functions, types, and
methods. This information is displayed currently only in HTML output.
Functions, types, and methods introduced as part of Go 1 are not
annotated, as their presence at that version is implied.

This change does not address constants or variables, and completely
ignores the syscall package. The former are future work, the latter is
likely an exercise in futility. In all cases, this is because the story
around displaying the version information is not well developed.

5c8013c561 cmd/guru: re-use buffer for reading files
I felt guilty about leaving 2% on the table in CL 108878,
so I thought I'd get it a different way.

Teach readFile to accept a re-usable bytes.Buffer to read into,
to reduce the amount of garbage created.

To limit the possible memory impact of giant files,
only re-use the buffer for the duration of a single package.
Even that is enough to help.

It also improves the output:
Now the initial result is referred to from the perspective of
the query site, rather than from the perspective of the package
containing the query object, which seems more natural.

d4c6246f3e cmd/guru: parallelize loop in globalReferrersPkgLevel
This change parallelizes the outer loop in globalReferrersPkgLevel,
which loops over packages to inspect.

There is also an easily parallelizable inner loop.
However, parallelizing it adds complication
(deffiles needs a mutex, inQueryPackage requires a wait group)
and offers only a 2% speed-up.

Benchmarks for this change, looking for encoding/json.MarshalIndent:

name       old time/op       new time/op       delta
Referrers        5.31s ± 2%        4.67s ± 3%  -11.95%  (p=0.000 n=10+10)

1e1ec013b9 cmd/guru: optimize global pkglevel referrer queries
Global, package-level queries can be done without typechecking.
This makes it significantly cheaper.

Instead of typechecking, consider all packages that directly
import the query package. In each of those packages, filter out:

* files that don't contain the query name
* files that don't import the query package

Fully parse the remaining files and look for selector expressions
matching the query package and name.

There are a few twists (dot imports, the query package, xtests).
They are described, along with how they are handled,
in the large comment at the beginning of globalReferrersPkgLevel.

On my machine and GOPATH, this reduces typical time
needed to find referrers to encoding/json.MarshalIndent
from (roughly)

real	0m39.946s
user	2m27.844s
sys	0m54.774s

to (roughly)

real	0m5.687s
user	0m15.793s
sys	0m16.001s

The processing of packages could be parallelized;
that is left for a future change, to ease reviewing.

Benefits from that will be limited;
building the reverse import graph accounts for 73%
of the runtime, and that is dominated by syscalls.

Optimization idea from Alan Donovan.

836e0f611e cmd/goyacc: fix an off-by-one error in lineno tracking
Previously, goyacc's line number tracking would run off by one whenever
a multiline comment was used inside of an action, like so:

    expr:
        TOKEN
        {
            /* Hello. */
        }

This is because the character after the multi-line comment close marker
(i.e., the character immediately after `*/`) was blindly printed out
instead of properly accounted for. A newline character after a
multi-line comment would fail to increment lineno, for example, and any
error messages generated after that point would refer to the wrong line.
Similarly, a variable reference after a multi-line comment, like

    $$.val = &someStruct{Value: /* oops */$1}

would copy the $ literally into the resulting Go code. (This was not a
problem in practice because multi-line comments are typically followed
by whitespace.)

Adjust the control flow so the character after the multi-line comment
close marker character gets run through the relevant switch statement
and accounted for.

d11f6ec946 blog: serve relative links when run locally
Currently, links inside blog articles are absolute links to golang.org.
But when a godoc server is run locally, the blog package should
serve local links pointing to the local godoc server. It is not possible
to simply change the links inside the blog templates to relative urls
because the blog articles are independant pages on their own.
And moreover, they are served from blog.golang.org.

Rather, the blog package consumes and serves blog articles.
So, a flag was added in the Config struct to denote whether
to convert the links or not. This flag is then set from the
call site in godoc package where the blog server is initialized from.

This was required because "golang.org/x/tools/blog" is a package
which can be used by other code to serve blog pages and not just godoc.
This preserves existing functionality for all working code which
imports "golang.org/x/tools/blog" and changes the functionality only
when a godoc server is run locally.

And while here, replace relevant bytes.Buffer occurences
with strings.Builder.
