Now key types can be implemented outside the package that holds labels or events, they should be.
This prevents the large list of types from poluting the public interface of the core packages.

I was curious about why were logging errors during type-checking in
tests, and the answer turned out to be a bit more sinister than I
expected. We were getting type error messages without filepaths, so I
tried to reproduce it in the playground and wasn't able to. I realized
that these errors were coming from were coming from the "fixed" version
of the AST that we pass to the type checker.
Adding fake positions to our fake Cond statements trivially fixes the
logging issue, but it does nothing to handle the fact that the error
makes no sense to the user - because it applies to something that's not
in the source code. I figured we have two options: (1) skip type errors
for all packages with "fixed" ASTs, or (2) add something to the error
messages to indicate that the source code may not match. Starting with
(1) here, and if it becomes a problem, we can move to 2. All ASTs that
we fix have *ast.BadExpr in them, meaning that, by definition they have
parse errors which we will preferentially show those errors to users in
diagnostics (so I'm not sure how to test this).

This change is the first step in handling golang/go#38136. Instead of
creating multiple diagnostic reports for type error analyzers, we add
suggested fixes to the existing reports. To match the analyzers for
FindAnalysisError, we add an ErrorMatch function to source.Analyzer.
This is not an ideal solution, but it was the best one I could come up
with without modifying the go/analysis API. analysisinternal could be
used for this purpose, but it seemed to complicated to be worth it, and
this is fairly simple. I think that go/analysis itself might need to be
extended for type error analyzers, but these temporary measures will
help us understand the kinds of features we need for type error
analyzers.
A follow-up CL might be to not add reports for type error analyzers
until the end of source.Diagnostic, which would remove the need for the
look-up.

switch {
ca<>
}
This gets parsed as:
switch {

Even if we manually recover the "ca" token, "<>" is not positioned
inside the switch statement anymore, so we don't know to offer "case"
and "default" candidates. To work around this, we move the closing
brace down one line yielding:
switch {

So, if a user decides to add an import that is not in their modcache, we run diagnostics as normal and the ModTidyKey's imports field gets updated with the new import, we run `go mod tidy` but since the file was not saved yet, nothing changes. Then when the user eventually saves their file, we do not rerun `go mod tidy` because the imports hash has not changed from the time the file was in overlay to the time the file was saved on disk. To be able to account for this, we need the invalidate the ModTidyKey when imports change between saves.

For testability, and to allow the exchange of debug information when
forwarding the LSP, it will be necessary to access debug information
stored in cache objects. This is cumbersome to do if our constructors
return source interfaces rather than concrete types.
This CL changes cache.New and (*Cache).NewSession to return concrete
types. This required removing NewSession from source.Cache. I would
argue that this makes sense from a philosophical perspective: everything
in the source package operates in a context where the Session and Cache
already exist.

Dangling selectors such as:
func _() {
x.
}
var x struct { i int }
tend to wreak havoc on the AST. In the above example you didn't used
to get completions because the declaration of "x" was missing from the
AST.
We now work around this issue by inserting a "_" into the source code
before parsing to make the selector valid:
func _() {
x._ // <-- insert "_" here
}
var x struct { i int }
This makes completion work as expected because the declaration of "x"
is present in the AST.
I had to change fixAST() to be called before fixSrc() because
otherwise this new workaround in fixSrc() breaks the "accidental
keyword" countermeasures in fixAST().

In cases like:
func _() {

func foo() {}
Completing at "<>" does not include "foo" because the missing "if"
opening curly brace renders the rest of the file unparseable. "foo"
doesn't exist in the AST, so as far as gopls is concerned it doesn't
exist at all.
To fix this, we detect when a block is missing opening "{" and we
insert stub "{}" to make things parse better. This is a different kind
of fix than our previous *ast.BadExpr handling because we must reparse
the file after tweaking the source. After reparsing we maintain the
original syntax error so the user sees consistent error messages. This
also avoids having the "{}" spring into existence when the user
formats the file.

Completion often fails when the completion prefix happens to be a
keyword. We previously tried to fix this with AST surgery, but
often the accidental keyword is not apparent looking at the AST.
For example:
chan<>
foo()
parses as CallExpr{Fun: ChanType{Value: Ident{"foo"}}} with very few
hints that something is wrong, and:
default
foo()
is completely omitted from the AST.
Rather than look in the AST, we now instead manually look for a
keyword token that contains the completion position. If we find one,
we treat that as our surrounding identifier.

The go command gets mad if go.mod has changed since it started, e.g.
because a new dependency was added by a concurrent go list call. Retry
loads if they hit a concurrency problem. See the comment for more
details.
Testing this is awkward. I ran a background script that constantly
modified the go.mod file and observed that gopls waited until it was
killed and then recovered.

The go/packages workaround to hide errors for overlay packages doesn't
seem to work well. It's easier to just hide list errors in gopls
diagnostics unless the package genuinely failed to type-check. Check if
the package has missing dependencies as an approximation of if it is
well-typed.
This required some additional special casing for the import cycle error
detection, which now causes them to have duplicate diagnostics. It's a
rare enough case that this doesn't concern me, but we should clean this
up at some point.

go/packages overlay handling only really works for contains queries
(file=), so our approach of reloading packages by package path (for
workspace packages) wasn't handling newly created packages that need to
be handled through overlays. Workaround this by reloading metadata for
individual files that are missing it by running extra contains queries
(only after the first metadata load for package paths). Be careful not
to reload the same file multiple times if the first load did not succeed.
Somewhat related, clear out `go list` errors in packages that go
through overlay handling, since they will often be rendered irrelevant.
I'm not sure if this is the right move, but if it's not, then we will
have to do extra work to disregard those errors in gopls.

A file b/b.go with package name "b" exists on disk. A package
b/b_test.go with no content exists on disk. There is an overlay for
b/b_test.go that contains the package name "b". Running packages.Load
for file=b/b_test.go will result in a failure to load package b
[b.test]. This change adds this test to the go/packages tests.
This case is fixed by restricting the fallback logic in
runContainsQueries. We only attempt to construct an ad-hoc package if
the original package was returned with no GoFiles.
Also, a minor change to the gopls error parsing code that fixes a case
in which diagnostics were being sent without corresponding files.

open in the editor. Reverse dependencies are no longer needed for
source.Diagnostics because they will be invalidated when the snapshot is

This even works for go.mod files because all of workspace-level `go list`s

Also, the `go env` variables that are collected at inconsistent times

is recreated if the environment changes.
I had originally hoped that the initial call to `go env` and the
-modfile detection could become part of this parallel initialization as
well, but you can't create a *packages.Config until the temporary
modfile has been set up, so it still makes sense to do that on view
create. This is, however, the reasoning behind the refactorings in
the -modfile detection in this CL. The main changes are a few renamings
and a split between snapshot.ModFiles and view.modFiles to maximize the

This change adds the -e flag to ensure that we get the release tags when we are checking if the go version is at least 1.14. This also adjusts the check to be more lenient when it comes to processing the output of the version check.
This also fixes another issue where if the version is not 1.14 we were publishing empty diagnostics for an empty uri. This arose because we did not check if there was a valid go.mod file before we published the reports.

This change removes functions from the snapshot that return package IDs.
We prefer PackageHandles, since getting PackageHandles in a granular
fashion is not effective and causes us to spawn many `go list`
processes. By only ever returning PackageHandles, we can batch metadata
reloads for workspace packages. This enables us to add a check to
confirm that the snapshot is in a good state before returning important
data, like reverse dependencies and workspace package handles.

Some other changes had to be made while debugging. In particular, the

We have multiple use cases for scanning: goimports, import completion,
and unimported completions. All three need slightly different features,
and the latter have very different performance considerations. Scanning
everything all at once and returning it was not good enough for them.
Instead, design the API as a series of callbacks for each
directory/package: first we discover its existence, then we load its
package name, then we load its exports. At each step the caller can
choose whether to proceed with the package. Import completion can stop
before loading exports, goimports can apply its directory name
heuristics, and in the future we'll be able to stop the scan short once
we've found all the results we want for completions.
I don't intend any significant changes here but there may be some little
ones around the edges.
