The main goal is to push the package variant logic from internal/lsp
into internal/lsp/source so all users of internal/lsp/source benefit.
"references" and "rename" now have top-level source.References() and
source.Rename() entry points (as opposed to hanging off
source.Identifier()). I expanded objectsAtProtocolPos() to know about
implicit objects (type switch and import spec), and to
handle *ast.ImportSpec generically. This gets rid of special case
handling of *types.PkgName in various places.
The biggest practical benefit, though, is that "references" no longer
needs to compute the objectpath for every types.Object comparison it
does, instead using direct types.Object equality. This speeds up
"references" and "rename" a lot.
Two other notable improvements that fell out of not using
source.Identifier()'s logic:
- Finding references on an embedded field now shows references to the
field, not the type being embedded.
- Finding references on an imported object now works
correctly (previously it searched the importing package's dependents
rather than the imported package's dependents).
Finally, I refactored findIdentifier() to use pathEnclosingObjNode()
instead of astutil.PathEnclosingInterval. Now we only need a single
call to get the path because pathEnclosingObjNode() has the
"try pos || try pos-1" logic built in.

This change moves to our ultimate approach of diagnostics the snapshot
on every file change, instead of carefully picking which files and
packages to diagnose. Analyses are shown for packages whose files are
open in the editor. Reverse dependencies are no longer needed for
source.Diagnostics because they will be invalidated when the snapshot is
cloned, so diagnosing the entire snapshot will bring them up to date.
This even works for go.mod files because all of workspace-level `go list`s
will be canceled as the user types, and then we trigger an uncancellable
go/packages.Load when the user saves. There is still room for improvement
here, but it will require much more careful invalidation of metadata for
go.mod files.

...there's actually no guarantee that the incoming requests will be

serialization. The only way to guarantee previous notifications have
been processed is to send another request. I didn't feel like adding

This change moves as much view initialization code into the
initialization function, instead of having it happen on view create.
Also, the `go env` variables that are collected at inconsistent times
are all collected on view creation. That is sufficient, since the view
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
amount of work done in the view. I changed view.modfiles to moduleInformation
because I thought we might want to store additional information there at some
point. Rohan, please let me know if you disagree with any of the changes I made,

these options more effectively. This results in some modifications in
the tests.
Additionally, the fuzzyMatching and caseSensitive boolean flags are
merged into one setting, matcher, which can be used to specify the type
of matcher that is used for completion. Other requests (notably
workspaceSymbols) may need to use a matcher in the future.

requests, in order to determine if the package contained any parse
errors. We can get this information directly from the ParseGoHandle, so
there is no need to check the package. This will prevent `go list`
errors from making their way into formatting requests, for which a `go
list` really is not needed.

Resolvers are lazy initialized. That worked fine until the addition of
the scan semaphore -- it's not a good idea to create that lazily, since
you can't synchronize on a channel that doesn't exist.
Specifically, this caused a gopls hang when completion finished without
needing to use the resolver. In that case, we'd call ClearForNewScan/Mod
on an uninitialized resolver, and then hang receiving from a nil
channel.
Instead, eagerly initialize where convenient, and particularly the scan
semaphore.

Filesystem walks of large GOPATHs/module caches can take seconds,
especially on systems with slow filesystems like MacOS and WSL. We don't
want to block completion requests on walks finishing. At the same time,
cancelling a walk midway through results in an unusable cache, where we
don't know which parts have been scanned so far.
The best option is to run the walks in a separate goroutine. Then we can
detach and let them finish. On the other side, we need to be able to
reattach for the next completion request.
Introduce a new method on caches, ScanAndListen, which first processes
all the items in the cache, then notifies of any new items. This allows
us to reattach to an existing scan without missing anything.
The background scan introduces concurrency to the resolvers where there
wasn't any before. We can't use mutexes, because there's no way to stop
Lock() when a context expires. Use a 1-element semaphore channel to
accomplish the same effect.
Along the way: Only rescan GOPATH if the resolver has been cleared. None
of this makes sense for GOPATH without that. Fix a bug where we were
scanning the main module twice in module mode. Stop loading exports in
module tests, it slows them down a ton.

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.

Unimported completions are always low-priority. If the user already

There's no point in calculating any of them.

We now support taking the address of objects to make better completion
candidates. For example:
i := 123
var p *int = <> // now you get a candidate for "&i"
This required that we track addressability better, particularly when
searching for deep candidates. Now each candidate knows if it is
addressable, and the deep search propagates addressability to child
candidates appropriately.
The basic propagation logic is:
- In-scope *types.Var candidates are addressable. This handles your
basic "foo" variable whose address if "&foo".
- Surrounding selector is addressable based on type checker info. This
knows "foo.bar.<>" is addressable but "foo.bar().<>" isn't
- When evaluating deep completions, fields after a function call lose
addressability, but fields after a pointer regain addressability. For
example, "foo.bar()" isn't addressable, but "foo.bar().baz" is
addressable if "bar()" returns a pointer.

This is the start of a significant refactoring to implementations,
references, and rename (i.e. everything that searches across
packages). The main goal of the refactoring is to push the package
variant logic from internal/lsp into internal/source so that all users
of source benefit, not just internal/lsp. It also makes it easier to
write tests for various cases because the source tests invoke the
source package directly (so previously did not include all the package
variants).
Currently source.Identifer() handles lots of disparate use cases.
Things like definition and hover don't care about package variants but
do care about other random bits of info that may not apply to
implementations or references. So, I'm splitting implementations out
from source.Identifier. As I work through references and rename
hopefully things will end up separated into smaller chunks.
I also improved implementation deduping to happen earlier. I thought I
could dedupe using obj.Pos(), but mirror objects in package variants
have different positions (suggesting they aren't reusing the
same *ast.File). Instead I used token.Position to dedupe.

The situation in golang/go#35638 was as follows:
didOpen main.go creates a snapshot that knows main.go is in package
"mod.com".
didChange main.go creates a snapshot. When a file changes, we discard
its contents by leaving the file handle out of the "files" map.
didOpen const.go creates a snapshot, and attempts to invalidate the
metadata for packages in the same directory.
The way we detect packages in the same directory is by iterating through
the files in the snapshot. But we threw away the only file in "mod.com"
in step 2 when its contents changed. If a diagnostics run happened to
get in between the two steps, it would re-load main.go and the bug would
go away. If not, step 3 would find no files and fail to invalidate
"mod.com".
The best way to fix this is to insert the new file handle eagerly during
cloning. That way there's no confusion.

Having nil ranked normally causes it to show up as the top candidate
in cases like:
context.WithCancel(<>) // "nil" shows up before "context.Background()"
"context.Background()" gets a slight score penalty since it is a deep
completion, so "nil" is ranked highest.
Sometimes you do want "nil", but it's such a short identifier you
probably aren't leaning too heavily on autocompletion. I think it
makes sense to optimize for the case when you want something non-nil.

that contain our starting identifier.

package foo
func Foo() {}
-- foo/foo_test.go --
package foo
func TestFoo(t *testing.T) {}

import "foo"
func _() {

We would start searching from the foo.test variant, but we wouldn't
search package bar at all because bar does not import foo.test, it
imports plain foo. Now we search from both foo and foo.test (you still

invalidate the foo.test and foo packages. Invalidating foo is not
necessary since it does not depend on any test files. Furthermore, it
caused problems because nothing would refetch foo's metadata until
foo.go changed, so various things (such as finding implementations in

We previously only searched for implementations of the object we found
in the "widest" package variant. We instead need to search all
variants because each variant is type checked separately, and
implementations can be located in packages associated with different
variants.
For example, say you have:
-- foo/foo.go --
package foo
type Foo int
type Fooer interface { Foo() Foo }
-- foo/foo_test.go --
package foo
func TestFoo(t *testing.T) {}
-- bar/bar.go --
package bar
import "foo"
type impl struct {}
func (impl) Foo() foo.Foo { return 0 }
When you run find-implementations on the Fooer interface, we
previously would start from the (widest) foo.test's Fooer named
type. Unfortunately bar imports foo, not foo.test, so bar.impl
does not implement foo.test.Fooer. The specific reason is that
bar.impl.Foo returns foo.Foo, whereas foo.test.Fooer.Foo returns
foo.test.Foo, which are distinct *types.Named objects.
Starting our search instead from foo.Fooer resolves this issue.
However, we also need to search from foo.test.Fooer so we match any
implementations in foo_test.go.

We don't distinguish between genuine errors and context cancellation in
diagnostics, which often results in superfluous logging of these errors.
Avoid spamming the logs with them by checking.
Also, remove the logic for sending undelivered diagnostics. It's a relic
of old bugs and isn't useful.

When searching for implementations we look at all packages in the
workspace. We do a full parse since we need to look for non-exported
types and look in functions for type declarations. However, we always
type check a package's dependencies in export-only mode to save work.
This leads to what I call the "two world" syndrome where you have both
the export-only and full-parse versions of a package in play at once.
This is problematic because mirror objects in each version do not
compare equal.
For example:
-- a/a.go --
package a
type Breed int
const Mutt Breed = 0
type Dog interface{ Breed() Breed }
-- b/b.go --
package b
import "a"
type dog struct{}
func (dog) Breed() a.Breed { return a.Mutt }
---
In this situation, the problem is "b" loads its dependency "a" in
export only mode so it gets one version of the "a.Breed" type. The
user opens package "a" directly so it gets fully type checked and has
a second version of "a.Breed". The user searches for "a.Dog"
implementations, but "b.dog" does not implement the fully-loaded
"a.Dog" because it returns the export-only version of the "a.Breed"
type.
Fix it by always loading in-workspace dependencies in full parse mode.
We need to load them in full parse mode anyway if the user does find
references or find implementations.
In writing a test I fixed an incorrect import in the testdata. This
uncovered an unrelated bug which made a different implementation test
very flaky. I disabled it for now since I couldn't see a fix simple
enough to slip into this commit.

Sometimes the prefix of the thing you want to complete is a keyword.
For example:
variance := 123
fmt.Println(var<>)
In this case the parser produces an *ast.BadExpr which breaks
completion. We now repair this BadExpr by replacing it with
an *ast.Ident named "var".
We also repair empty decls using a similar approach. This fixes cases
like:
var typeName string
type<> // want to complete to "typeName"
We also fix accidental keywords in selectors, such as:
foo.var<>
The parser produces a phantom "_" in place of the keyword, so we swap
it back for an *ast.Ident named "var".
In general, though, accidental keywords wreak havoc on the AST so we
can only do so much. There are still many cases where a keyword prefix
breaks completion. Perhaps in the future the parser can be
cursor/in-progress-edit aware and turn accidental keywords into
identifiers.
Fixesgolang/go#34332.
PS I tweaked nodeContains() to include n.End() to fix a test failure
against tip related to a change to go/parser. When a syntax error is
present, an *ast.BlockStmt's End() is now set to the block's final
statement's End() (earlier than what it used to be). In order for the
cursor pos to test "inside" the block in this case I had to relax the
End() comparison.

The early return logic for didOpen events in

snapshot, which was in turn stopping the versions from being updated.
This exposed a fundamental issue in the way we were calculating
workspace diagnostics. Since we weren't waiting for diagnostics to be
completed for an entire snapshot before replying that the server had
been initialized, snapshots were being cloned without any type
information. For quickfix code actions, we assume that we have all
information cached (since we need to have sent the diagnostics that the
quickfix is mapped to), so we were not finding the cached analysis
results.
To handle this in the short-term, we key analyses by their names, and
then regenerate results as-needed for code actions. This is technically
more correct than simply assuming that we have the analyses cached. In a
follow-up CL, I will send a follow-up that will make sure that
snapshots "wait" on each other to be fully constructed before being
cloned.

start (Range).Span() by translating into positions in the authored file,
then calculate offsets from that.
A lot of call sites outside of the LSP don't pass the Converter, but
they probably don't matter much. I think everything inside does because
it ends up using mappedRange.

In cases like:
var foo []bytes.Buffer
foo = append(foo, <>)
you will now get a literal candidate "bytes.Buffer{}". Previously we
were skipping all literal candidates at the variadic position, but the
intention was to only skip literal slice candidates (i.e.
"[]bytes.Buffer{}" in the above example).
I also improved the literal struct snippet to not leave the cursor
inside the curlies when the struct type has no accessible fields.
Previously it was only checking if the struct had no fields at all.
This means after completing in the above example you will end up with
"bytes.Buffer{}<>" instead of "bytes.Buffer{<>}", where "<>" denotes
the cursor.

Code generation has been unified, so that tsprotocol.go and tsserver.go
are produced by the same program. tsprotocol.go is about 900 lines shorter,
partly from removing boilerplate comments that golint no longer requires.
(And partly by generating fewer unneeded types.)
The choice made for a union type is commented with the set of types. There
is no Go equivalent for union types, but making themn all interface{}
would replace type checking at unmarshalling with checking runtime
conversions.
Intersection types (A&B) are sometimes embedded (struct{A;B;}, and
sometimes expanded, as they have to be if A and B have fields with the
same names.
There are fewer embedded structs, which had been verbose and confusing to
initialize. They have been replaced by types whose names end in Gn.
Essentially all the generated *structs have been removed. This makes
no difference in what the client sends, and the server may send a {}
where it previously might have sent nothing. The benefit is that some
nil tests can be removed. Thus 'omitempty' in json tags is just
documentation that the element is optional in the protocol.
The files that generate this code will be submitted later, but soon.

we weren't giving "buf" a good score. When comparing the candidate
type *bytes.Buffer to the (variadic) expected type []io.Writer we were
turning the candidate type into []*bytes.Buffer. However, of course,
[]*bytes.Buffer is not assignable to []io.Writer, so the types didn't
match. Now we instead turn the expected type []io.Writer into
io.Writer and compare to *bytes.Buffer.
I fixed the @rank test note to check that the candidates' scores are
strictly decreasing. Previously it would allow candidates with the
same score if they happened to be in the right order. This made it
easier to right a test for this issue, but also uncovered an issue
with untyped completion logic. I fixed it to do the untyped constant
check if _either_ the expected or candidate type is
untyped (previously it required the candidate type to be untyped).

to different files, either within the workspace or outside of it. We add
a source.FileAction type to pass into the internal/lsp/cache package and
handle the difference between opening and creating a file.
Now that we load all packages in a workspace by default, we no longer
need to re-load a file on open. This CL should enable CL 206883 to work
correctly.

If a user is typing fast, they will quickly invalidate many snapshots.
We don't want to stack up a bunch of stale type check and analysis
operations, so we should propagate cancellation through the cache.
Handles are long-lived, so we may cancel an operation only to
restart it again later. Also, there may be multiple operations waiting on
the same computation, and just because one is cancelled doesn't mean we
should necessarily stop. The easiest way to support all that was to add
an explicit state to each handle, and track the number of waiters.
See the code for more details on Handle life cycles.
As far as I can tell, the rest of gopls is prepared for this behavior.
I added an explicit check to the type checking code, where I was worried
it might get overly confused. But long-term it would probably be good to
return an error from Get.

Previously we were erroneously suggesting a "func() {}" literal in
cases like:
http.Handle("/", <>)
This was happening because saw that the http.HandlerFunc type
satisfied the http.Handler interface, and that http.HandlerFunc is a
function type. However, of course, you can't pass a function literal
to http.Handle().
Make a few tweaks to address the problem:
1. Don't suggest literal "func () {}" candidates if the expected type
is an interface type.
2. Suggest named function types that implement an interface. This
causes us to suggest "http.HandlerFunc()" in the above example.
3. Suggest a func literal candidate inside named function type
conversions. This will suggest "func() {}" when completing
"http.HandlerFunc(<>)".
This way the false positive func literal is gone, and you still get
literal candidates that help you use an http.HandlerFunc as an
http.Handler. Note that this particular example is not very compelling
in light of http.HandleFunc() which can take a func literal directly,
but such a convenience function may not exist in other analogous
situations.

- When completing foo("hi", <>), we prefer candidates of type

- When completing foo(<>), we use a snippet to add on the "..."
automatically to candidates of type []string.
I also fixed completion tests to work properly when you have multiple
notes referring to the same position. For example:
foo() //@rank(")", a, b),rank(")", a, c)
Previously the second "rank" was silently overwriting the first
because they both refer to the same ")".

Loading completion suggestions can be slow, especially in GOPATH mode
where basically anything can change at any time. As a compromise, cache
everything for 30 seconds. Specifically, after a completion operation
finishes, if the cache is more than 30 seconds old, refresh it
asynchronously. That keeps user-facing latency consistent, without
chewing up CPU when the editor isn't in use. It does mean that if you
walk away for an hour and come back, the first completion may be stale.
In module mode this is relatively benign. The only things the
longer caching affects are the main module and replace targets, and
relevant packages in those will generally be loaded by gopls, so they'll
have full, up-to-date type information regardless.
In GOPATH mode this may be more troublesome, since it affects
everything. In particular, go get -u of a package that isn't imported
yet won't be reflected until the cache period expires. I think that's a
rare enough case not to worry about.

When proposing packages to import, we can propose more relevant packages
first. Introduce that concept to the pkg struct, and sort by it when
returning candidates.
In all cases we prefer stdlib packages first. Then, in module mode, we
prefer packages that are in the module's dependencies over those that
aren't. We could go further and prefer direct deps over indirect too,
but I didn't have the code for that handy.
I also changed the alphabetical sort from import path to package name,
because that's what the user sees first in the UI.

When our expected type is a named type from another package, we now always
search that other package for completion candidates, even if it is not currently
imported.
Consider the example:
-- foo.go --
import "context"
func doSomething(ctx context.Context) {}
-- bar.go--
doSomething(<>)
"bar.go" doesn't import "context" yet, so normally you need to first import
"context" through whatever means before you get completion items from "context".
Now we notice that the expected type's package hasn't been imported yet and give
deep completions from "context".
Another use case is with literal completions. Consider:
-- foo.go --
import "bytes"
func doSomething(buf *bytes.Buffer) {}
-- bar.go--
doSomething(<>)
Now you will get a literal completion for "&bytes.Buffer{}" in "bar.go" even
though it hasn't imported "bytes" yet.
I had to pipe the import info around a bunch of places so the import is added
automatically for deep completions and literal completions.

CL 203820 removes an assumption in go/build that srcDir is in the main

other mechanism for callers to communicate the correct location of the
main module.
Fortunately, we already have a WorkingDir field on the ProcessEnv
struct that does exactly that. We can simply propagate it through if
the corresponding field is present on go/build.Context.

Previously, goimports half-supported vendor mode -- it searched the
module cache on some code paths and the vendor dir in others. That
seemed to work okay, probably because people happened to have a populated
module cache. In 1.14, it's much more likely that people will work
solely from the vendor directory.
In this CL we bite the bullet and fully support vendor mode. 1.14 makes
this particularly challenging by disabling list -m ... in vendor mode, and
by enabling it automatically under some circumstances. We need to mirror
that behavior, which means knowing whether we're running with 1.14, and
figuring out whether vendoring should be enabled given that. We collect
the information we need with a list -m -f query just on the main module.
If vendor mode is enabled, we throw away all the modules and replace
them with a single pseudo-module rooted at /vendor. Everything basically
works at that point.

When VSCode applies its own fuzzy matching/filtering/ranking logic to
completion candidates, it can end up reordering and even omitting some
of our candidates. It is mainly a problem with deep completions (i.e.
VSCode downranks or completely hides deep completion candidates that
should be ranked at the top).
We now trick VSCode into not reordering our candidates by setting each
candidate's "filterText" to the completion prefix. This makes every
candidate look like an identically perfect match, so VSCode just
maintains the order specified by "sortText".
Note that we don't do this trick if server side fuzzy matching and
deep completions are disabled. In this case unimpeded client side
candidate filtering is necessary.
