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.

Unimported packages may be suggested as completion items. Since these
are not yet imported, they should be ranked lower than other candidates.
They also require an additional import statement to be valid, which is
provided as an AdditionalTextEdit.
Adding this import does not use astutil.AddNamedImport, to avoid
editing the current ast and work even if there are errors. Additionally,
it can be hard to determine what changes need to be made to the source
document from the ast, as astutil.AddNamedImport includes a merging
pass. Instead, the completion item simply adds another import

The merging pass was added to astutil.AddNamedImport in order to address

This functionality is more of a formatting change than a fix imports

FormatOnly. The formatting was only applied when an import was added
(not renamed or deleted). This change makes formatting by goimports
more consistent across runs and is not dependent on the exact fixes

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

Since `parseLimit` is actually only used to limit IO access, let's also

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.
