28aef64757 go/internal/gcimporter: return error from BExportData
This change adds an error return value to BExportData and replaces the
various calls to log.Fatal within that library with panics that
propagate the internal error up the call stack to BExportData which
recovers and returns the error.

Fixes golang/go#25431

48418e5732 godoc: display "go vet" errors before the output of a program
This change adds an option to run "go vet" for the playground program
and display errors before any output. To enable this, the playground
function has to be supplied with opts.enableVet set to true.
Vet check is performed only for succesfully run programs,
meaning that the "/compile" endpoint returned no errors.

This change highlights lines printed to stderr as errors (in red).

There is a corresponding change for the Playground: CL 100776.

ae8027637c godoc/static: add test for static.go file generation
Moved the code which generates static.go to remain in the static package.
This makes the code testable.

Additionally, it is very easy for developers to forget to run "go generate"
to update static.go. Because while development, the templates directory
can be directly passed as a flag to read the files from it.

This test catches that.

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.

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

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.

165bdd618e imports: fix races in findImportGoPath
Before this change, findImportGoPath used a field within the
(otherwise read-only) structs in the dirScan map to cache the distance
from the importing package to the candidate package to be imported. As
a result, the top-level imports.Process function was not safe to call
concurrently: one goroutine could overwrite the distances while
another was attempting to sort by them. Furthermore, there were some
internal write-after-write races (writing the same cached distance to
the same address) that otherwise violate the Go memory model.

This change fixes those races, simplifies the concurrency patterns,
and clarifies goroutine lifetimes. The functions in the imports
package now wait for the goroutines they spawn to finish before
returning, eliminating the need for an awkward test-only mutex that
could otherwise mask real races in the production code paths.

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.

Fixes golang/go#22681

1c0c7a8cce imports: Process should accept nil src
The comment of Process() implies src can be nil, but it didn't handle
nil src correctly before because parse() doesn't expect nil src.
Passing []byte(nil) to parser.ParseFile() results in error and parse()
tries to parse again by modifying src if src is statement list.

This problem isn't related with cmd/goimports because goimports doesn't
pass []byte(nil) to Process() as src.

8b3cccae50 godoc/vfs: improve implementation of RootType
- Removed the StandAlone and Asset root types as they were just there
for other vfses to satisfy the FileSystem interface and causing unnecessary
confusion. Returning just empty strings in those scenarios now to clarify
that it is a dummy placeholder.

- Removed the prefix "Fs" from RootType as it was unnecessary.

- Using the RootType type to pass down to the html templates
instead of converting to string. The templates are capable of converting
to the actual string representation when comparing the value.

16d1af8d88 godoc: group package home page list by root
This CL groups the package list into two groups - standard library(GOROOT),
and third-party code(GOPATH).

It also wraps the list with a collapsible div header used in the package
documentation page. This makes the entire page easy to view and manage, and also
makes it consistent with the rest of the pages.

To implement this, a new function was added to the filesystem interface
which returns the root type of the filesystem. In most cases, it is either GOROOT
or GOPATH. There are other kinds of filesystems which are not used in the home page,
so additional values have been added to satisfy the interface.

A side effect of this is that the html template code has become a bit spaghetti-like
with if conditions all over. This is because the same template is used to render
a package directory as well as the package home page. A better way is to use
two separate templates for the different tasks. This cleans out a lot of the
if conditions and make for a much cleaner code. This has been taken care in CL 101295.

96caea4103 godoc: fix runaway goroutine use
Previously we would spin up a new goroutine for every directory
we needed to parse. Since parent directories cannot exit until
children have exited, in large GOPATH directories we could have 8000+
goroutines evaluating directories concurrently. The race detector uses
tsan, and tsan can handle a maximum of 8192 concurrent threads at one
time.

Limit the number of concurrent threads. It is difficult to do this
in a way that does not involve a child being blocked on a parent
completing to spin up goroutines for itself to complete. Solve this by
completing work on the main thread if there are no additional workers
available to help complete work.

I was expecting limiting the concurrency to hurt performance, but it
actually significantly improves it. Benchmarks were performed using CL
94904 at tip, and with goroutines at 2, 4, and 8 times the number of
CPU's.

c4b4e4b0fa cmd/guru: fix .golden file (fix build)
This regression is due to https://go-review.googlesource.com/c/go/+/100235
which made the go/scanner behavior match the compiler's scanner by
not modifying filenames in line directives in any form. Specifically,
relative filenames now remain relative. This makes it easier to reason
about the behavior of the scanner but may require clients to adjust
those filenames.

If removing the longer path in the .golden file is not satisfactory,
the (scanner) client may have to massage positions returned via line
directives; or better, the line directives are created with extended
path information.
