0310561d58 internal/lsp: change the hover test to use normal editor methods
It was directly generating messages and sending them on the conn, now it
just uses an editor method like all the other tests.
It was also broken because it never opened the file it was hovering in, so I am
not sure it was testing anything useful before.

ef124de36d internal/jsonrpc2: change StreamServer to operate on Conn instead of Stream
Really the name is wrong now, but this is just a stepping stone towards removing
it entirely in favour of a new listener/dialer/server/client pattern, so I am
minimizing the churn by leaving the names alone for now.

1c0c6cf43e x/tools/internal/lsp/source: avoid panic in failing Highlight test
When testing Highlight the highlight count is checked against expected
number of highlights. If it doesn't match t.Errorf(...) is called and
the test continues.

A few lines below the test ranges over results using the index for both
result and expected result leading to a panic if there are less then
expected highlights.

This change fails fast with t.Fatalf(...) instead to avoid the panic.

5298e130f1 internal/lsp: lift up workdone instrumentation to didModifyFiles
Previously, workdone reporting was managed by the goroutine(s) that
compute diagnostics following a file change. The intention was to signal
when diagnostics resulting from file changes were complete.

This was buggy, in two ways:
 + When no snapshots are determined to require diagnosis, no work is
   reported.
 + If multiple snapshots required diagnosis, we'd get multiple work IDs.

Fix this by lifting up the 'work' to the level of didModifyFiles.

This allows things to shutdown gracefully, and removes special

2caf76543d internal/lsp/regtest: add a test that reproduces golang/go#38878
This test partially reproduces some strange behavior with creating
new tests files. In particular, it creates a new x test in a package
that already has a test variant and adds content with a missing import.

In the test, the import is never added. However, in my own experience
debugging this in VS Code, I see the import get added but the diagnostic
never get removed. One thing at a time though...

41453949f3 internal/lsp: regtests for removing files outside the editor
When a file with errors is removed outside the editor, sometimes its
errors are cleared by the editor and sometimes they are not. If the file
is still open in the editor gopls does not clear the errors, taking the
editor's version as the truth. Otherwise the errors are cleared.
(This behavior depends on the editor sending gopls a notification that
the workspace changed.)

There seems to be no good way yet to test that gopls takes no action after
receiving the didChangeWatchedFiles notification.

8e7acdbce8 all: replace build tags in tests with testenv helper

break up test organization.

Add a suite of testenv functions that check what Go version is in use.
Note that this is the logical Go version, as denoted by the release
tags; it should be updated at the beginning of the release cycle per
issue golang/go#38704.

For ease of reviewing, I'll merge/delete files in a followup CL.

6a7cf6184f internal/lsp/source: fix cached package name matching
I made a silly mistake and checked the prefix on the import path rather
than the package name, which obviously breaks everything other than
top-level stdlib packages.

Fix that, then tweak the ranking a bit. We now get deep completions, which
is nice, but filled up the results too fast. Now instead of 5 results of
any kind, we give up after 5 packages searched.

One line legal code like `package x; import "os"; func f() {}` was

all these cases are short enough that there is no appreciable penalty
from the extra parsing.

cf2d1e09c8 internal/lsp/source: offer smart "append()" completions
Assigning a slice to the appendage of itself is common and tedious
enough to warrant a special case completion candidate. We now offer
smarter "append()" candidates:

    var foo []int
    foo = app<> // offer "append(foo, <>)"
    fo<> // offer "foo = append(foo, <>)"

The latter is only offered if the best completion candidate is a
slice. It is inserted as the second-best candidate because it seems
impossible to avoid annoying false positives if it is ranked first.

I added a new debug option to disable literal completions. This was to
clean up some test logic that was disabling snippets for all tests
just to defeat literal completions. My tests were failing mysteriously
due to having snippets disabled, and it was hard to figure out why.

hide the hovertext link when the import path matches GOPRIVATE.

Implementing this was a little messy. To be optimal I had to thread
the value of goprivate through cache.view, and to be correct I had to
duplicate some code from cmd/go internal.

Regtest will follow after https://golang.org/cl/232983 is submitted.

7d3b6ebf13 internal/lsp/cache: pass UsesCgo to go/types
In CL 229779 I enabled Cgo type checking for go/packages, but we don't
actually type check there. We need to enable it in our own type checking
too.

No test updates because the negative effects are relatively subtle and
caught by an upcoming regtest.

866d71a317 internal/lsp/regtest: don't build unix_test for Plan 9
TestBadGOPATH tests for a empty element in the GOPATH list using
"GOPATH=:/path/to/gopath", assuming that ':' is the path list
separator. On Windows the test fails, because Windows path list
separator is ';'. Therefore this test isn't built for Windows.

On Plan 9, os.PathListSeparator is '\000', so the test fails
there too, and should not be built for Plan 9.

1762287ae9 internal/lsp: rename workspace symbol test symbols to avoid clash
In a later CL we include the fully qualified path to a symbol in the
Name field of SymbolInformation. This means that we end up with
matches like:

golang.org/x/tools/internal/lsp/workspacesymbol/b.WorkspaceSymbolVariableB

A fuzzy match against this name using the query "wsym" would match the
"workspacesymbol" of the import path as well as the
"WorkspaceSymbolVariableB" that is the symbol name itself.

Therefore we rename the symbols in the:

    internal/lsp/testdata/lsp/primarymod/workspacesymbol/...

from WorkspaceSymbol* to RandomGopher*, which allows our fuzzy matches
to be more precise.

0bd3dbed90 internal/lsp/fake: define Symbol method on Editor
In preparation for later changes to the implementation of the workspace
Symbol method, we add the Symbol method to fake.Editor. This requires
the definition of a number of associated fake types (editor-friendly,
byte-offset-based versions of protocol UTF16-based types) for example
fake.SymbolInformation and the types it references.

We also implement a basic regtest for the Symbol method, exposing Symbol
on regtest.Env like other LSP server methods. To aid with the writing of
Symbol result assertions, we provide some helper functions to simplify
the process of defining matches that are evaluated against the result
set.

ca5866bcf9 internal/lsp: add config option for SymbolMatch
In preparation for later changes to the workspace Symbol method, we add
a separate configuration option keyed by "symbolMatcher" that specifies
the type of matcher to use for workspace symbol requests. We also define
a new type SymbolMatcher, the type of this new option. We require
SymbolMatcher to be a separate type from Matcher because a later CL adds
a type of symbol matcher that does not make sense in the context of
other uses of Matcher, e.g. completion.

e48fac377d internal/lsp: change workspace symbols to use session config for matcher
WorkspaceSymbols matches symbols across views using the given query,
according to the matcher Matcher.

The workspace symbol method is defined in the spec as follows:

 > The workspace symbol request is sent from the client to the server to
 > list project-wide symbols matching the query string.

It is unclear what "project-wide" means here, but given the parameters
of workspace/symbol do not include any workspace identifier, then it has
to be assumed that "project-wide" means "across all workspaces".  Hence
why WorkspaceSymbols receives the views []View.

However, it then becomes unclear what it would mean to call
WorkspaceSymbols with a different configured Matcher per View.

Therefore we assume that Session level configuration will define the
Matcher to be used for the WorkspaceSymbols method.

As part of this change we also tidy up lsp_test.go and source_test.go to
remove some repetition.

da4261a3d0 internal/lsp/cmd: use JSON output for the inspect subcommand
I've been using the inspect command to find data about the daemon and

don't simply want to view the debug information: I want to script it.
This change removes the custom output formatting in favor of indented
JSON, so that we can do things like the following:

  tail -f $(gopls inspect sessions | gq -r .logfile)

Which tails the daemon logs for the current gopls binary version.

In VS Code, a workspace symbol query with an empty query parameter
is issued as soon as users open the symbol search box. There are many
symbols in a reasonably sized project and the chance that a user finds
a result in the randomly chosen 100 items out of those many symbols is
low. Thus, this first query is often useless.

Ignore this query and return an empty result immediately.
