In api/*.txt, interface declarations are represented with lines like:

Now when a file is deleted we force the file's packages to refresh

I made a couple other changes to watched file handling:
- Kick off diagnostics in a goroutine to match how DidChange works.
This will allow us to work through big sets of file changes faster,
and will save duplicated work once type checking can be canceled.
- Don't assume a watched file is only part of one view.
Two interesting cases we don't handle yet:
- If the deleted file was the only file in the package, we don't
currently update diagnostics for dependent packages. This requires
rejiggering how diagnostics are invoked a bit.
- If the deleted file is still open in the editor and then later
closed, we don't trigger metadata/diagnostics refresh on DidClose.

Improve the existing fix-the-AST code to better identify the
expression following the "go" or "defer" keywords:
- Don't slurp the expression start outside the loop since the
expression might only have a single token.
- Set expression end to the position after the final token, not the
position of the final token.
- Track curly brace nesting to properly capture an entire "func() {}"
expression.
- Fix parent node detection to work when BadStmt isn't first statement
of block.
- Add special case to detect dangling period, e.g. "defer fmt.". We
insert phantom "_" selectors like go/parser does to prevent the
dangling "." from messing up the AST.
- Use reflect in offsetPositions so it updates positions in all node
types. This code shouldn't be called often, so I don't think
performance is a concern.
I also tweaked the function snippet code so it properly expands
"defer" and "go" expressions to function calls. It thought it didn't
have to expand since there was already a *ast.CallExpr, but the
CallExpr was faked by us and the source doesn't actually contain the
"()" calling parens.
Note that this does not work for nested go/defer statements. For
example, completions won't work properly in cases like this:
go func() {
defer fmt.<>
}
I think we can fix this as well with some more work.

Downranking builtins causes weird interplay with other completion

productive.
Change it to not downrank builtins. In my testing with this change,
builtins never were ranked above lexical items with similar names. I
think this is because the "natural" order of completion items puts
builtins last, and we stable sort items by score, so their relative

The memoize store passes a detached context to the value getter

context and using the "real" request context. This would cause the
context.Canceled error to get cached and continue popping up in
various situations.
Fix by swapping the importer's context to the detached context. It is

correct to let the detached context escape the memoize function.

Invert "useDeepCompletions" config flag to "disableDeepCompletion" and
separate out "disableFuzzyMatching" which reverts to the previous
prefix matching behavior.
I separated fuzzy matching tests out to a separate file so they aren't
entangled with deep completion tests. In coming up with representative
test cases I found a couple issues which I fixed:
- We were treating a fuzzy matcher score of 0 as no match, but the
matcher returns 0 for candidates that match but have no bonuses. I
changed the matcher interface so that a score of 0 counts as a
match. For example, this was preventing a pattern of "o" from
matching "foo".
- When we lower a candidate's score based on its depth, we were
subtracting a static multiplier which could result in the score
going negative. A negative score messes up future score weighting
because multiplying it by a value in the range [0, 1) makes it
bigger instead of smaller. Fix by scaling a candidate's score based
on its depth rather than subtracting a constant factor.

Deep completions can take a long time (500ms+) if there are many
large, deeply nested structs in scope. To make sure we return
completion results in a timely manner we now notice if we have spent
"too long" searching for deep completions and reduce the search scope.
In particular, our overall completion budget is 100ms. This value is
often cited as the longest latency that still feels instantaneous to
most people. As we spend 25%, 50%, and 75% of our budget we limit our
deep completion candidate search depth to 4, 3, and 2,
respectively. If we hit 90% of our budget, we disable deep completions
entirely.
In my testing, limiting the search scope to 4 normally makes even
enormous searches finish in a few milliseconds. Of course, you can
have arbitrarily many objects in scope with arbitrarily many fields,
so to cover our bases we continue to dial down the search depth as
needed.
I replaced the "enabled" field with a "maxDepth" field that disables
deep search when set to 0.

Optimize a few things to speed up deep completions:
- item() is slow, so don't call it unless the candidate's name matches
the input.
- We only end up returning the top 3 deep candidates, so skip deep
candidates early if they are not in the top 3 scores we have seen so
far. This greatly reduces calls to item(), but also avoids a
humongous sort in lsp/completion.go.
- Get rid of error return value from found(). Nothing checked for this
error, and we spent a lot of time allocating the only possible error
"this candidate is not accessible", which is not unexpected to begin
with.
- Cache the call to types.NewMethodSet in methodsAndFields(). This is
relatively expensive and can be called many times for the same type
when searching for deep completions.
- Avoid calling deepState.chainString() twice by calling it once and
storing the result on the candidate.
These optimizations sped up my slow completion from 1.5s to
0.5s. There were around 200k deep candidates examined for this one
completion. The remaining time is dominated by the fuzzy
matcher. Obviously 500ms is still unacceptable under any
circumstances, so there will be subsequent improvements to limit the
deep completion search scope to make sure we always return completions
in a reasonable amount of time.
I also made it so there is always a "matcher" set on the
completer. This makes the matching logic a bit simpler.

Make use of the existing fuzzy matcher to perform server side fuzzy
completion matching. Previously the server did exact prefix matching
for completion candidates and left fancy filtering to the
client. Having the server do fuzzy matching has two main benefits:
- Deep completions now update as you type. The completion candidates
returned to the client are marked "incomplete", causing the client
to refresh the candidates after every keystroke. This lets the
server pick the most relevant set of deep completion candidates.
- All editors get fuzzy matching for free. VSCode has fuzzy matching
out of the box, but some editors either don't provide it, or it can
be difficult to set up.
I modified the fuzzy matcher to allow matches where the input doesn't
match the final segment of the candidate. For example, previously "ab"
would not match "abc.def" because the "b" in "ab" did not match the
final segment "def". I can see how this is useful when the text
matching happens in a vacuum and candidate's final segment is the most
specific part. But, in our case, we have various other methods to
order candidates, so we don't want to exclude them just because the
final segment doesn't match. For example, if we know our candidate
needs to be type "context.Context" and "foo.ctx" is of the right type,
we want to suggest "foo.ctx" as soon as the user starts inputting
"foo", even though "foo" doesn't match "ctx" at all.
Note that fuzzy matching is behind the "useDeepCompletions" config
flag for the time being.

By moving up the `parseLimit` so the reading of the file is only done
when it is allowed to start parsing the file, we stay well below the 256
files per process (as the `parseLimit` is currently set to 20).
Since `parseLimit` is actually only used to limit IO access, let's also

The bug manifests itself when a non-existent file is passed in as an
argument to gopls, causing a nil pointer dereference panic. This is due
to an attempt to reference the "mapper" attribute, which is not set if
the file is not found.
The resolution is to check for an informative error that is set on the
file instance after "getFile" is called and return it immediately to the
caller to allow the error to propagate up to the main() function and
print the error to stdout.
Testing:
--------
Non-existent file:
$ gopls -rpc.trace -v check gopls/doesnotexist.go
check: file:///Users/albertteoh/repo/tools/gopls/doesnotexist.go: open /Users/albertteoh/repo/tools/gopls/doesnotexist.go: no such file or directory

The imports ProcessEnv contains cached module and filesystem state. This change
allows gopls to use the same ProcessEnv and resolver across multiple calls to the
internal/imports library.
A ProcessEnv belongs to a view, because the cached module state depends
on the module that is open in the workspace.
Since we do not yet track whether the 'go.mod' file has changed, we
conservatively reset the cached state in the module resolver before
every call to imports.Process.

If typeCheck() returned an error, we could get into a state where a
package had an entry in the pcache, but the package's files had an
empty "pkgs" map. When we got a DidChange event for one of the files,
no packages would get invalidated since the file's "pkgs" was
empty. This resulted in the cached typeCheck() error persisting
indefinitely. Fix by never caching pcache entries on error.
An easy way to reproduce the problem was to delete the package name
from a file. For example, edit "package foo" to be just
"package". This caused the package to get stuck with an "AST for %s
has an invalid position" error.

logic.

A client can specify "IncludeDeclaration" in its ReferenceParams.
When they do so, we want to include the declaration, even if it was not
in the scope we searched for references.
Additionally, we also return the location of the declaration first in
the result array when it is included in the results.

The first deadlock involved differing mutex acquisition order in two
code paths:
1. loadParseTypecheck() holds the "mcache" mutex then eventually
acquires the "handleMu" file mutex.
2. (*goFile).invalidateContent() acquires the "handleMu" mutex first and
then the "mcache" mutex.
Fix by changing the acquisition order in invalidateContent().
The second deadlock involved the file watcher. The two code paths
involved were:
1. (*goFile).GetPackages() holds the view mutex and eventually calls
(*WatchMap).Watch, which acquires the watcher mutex.
2. (*session).openOverlay acquires the watcher mutex as it triggers a
file's callbacks, and then the callback
"(*goFile).invalidateContent" acquires the view mutex.
Fix by not holding the watcher mutex as we invoke the callbacks.

Instead of defaulting to a one sentence synopsis for documentation on
hover, allow the user to configure the amount of documentation they want
to see. Right now, the options are none, some (using go/doc.Synopsis),
or all. We should add a 4th, single-line, mode, which will allow clients
like vim-go to stop stripping off documentation on hover.

Add some extra smarts when evaluating untyped constants as completion
candidates. Previously we called types.Default() on the expected type
and candidate type, but this loses the untypedness of an untyped
constant which prevents it from being assignable to any type or named
type other than the untyped constant's default type.
Note that the added logic does not take into account the untyped
constant's value, so you will still get some false positive
completions (e.g. suggesting an untyped negative integer constant when
only a uint would do). Unfortunately go/types doesn't provide a way of
answering the question "is this *types.Const assignable to this
types.Type" since types.AssignableTo only considers a constant's type,
not its value.

Often anonymous functions can be passed as arguments to a function. In
these cases, it can be annoying for a user to see signature help for the
entire duration of their writing this function. This change detects if
the user is typing in a function literal and disables signature help in
