Currently array and slice literals don't work very well for
completion. When go/parser is not expecting a type, it often turns
array types (e.g. "[]int") into *ast.BadExpr, which messes up
completion because we can't figure out the prefix from *ast.BadExpr,
and *ast.BadExprs don't get type checked.
This change addresses the first problem of not being able to figure
out the prefix. If we see an *ast.BadExpr, we now blindly try to
reparse it as a composite literal by adding on "{}". If we end up with
an *ast.CompositeLit with an *ast.ArrayType "Type", we swap
the *ast.BadExpr for the *ast.ArrayType. This approach is dumb but
simple, and fixes lexical completions in array types.

We now continue deep completion search across function calls. The
function must take no arguments and return a single argument. For
example, when completing "fo<>" you might get candidates such as
"foo.bar().baz()".
Previously we would stop searching for deep completions when we hit a
function call. For example, we would stop at "foo.bar()", never
finding "foo.bar().baz()". At the time I was worried about the search
scope growing too large, but now that we dynamically limit the search
scope there isn't much left to worry about.

Previously we unconditionally qualified literal candidate types with
their package. For example:
var buf *bytes.Buffer
buf = &bytes.Bu<>
would complete to:
buf = &bytes.bytes.Buffer{}
Now we don't qualify the type if the cursor position is in the
selector of an *ast.SelectorExpr. We only generate literal candidates
for type names, so if we are in a selector then we can assume it is a
package qualified type (as opposed to an object field).
We also handle the insertion of "&" for literal pointers better. If you are in
the selector of an *ast.SelectorExpr, we prepend the "&" to the beginning of the
expression rather than the selector. For example, you will end up with
"&bytes.Buffer{}" instead of "bytes.&Buffer{}".

Normally you don't want literal candidates for basic types (e.g.
"int(0)") since you can type the literal value without the type name.
One exception is if you are creating a named basic type that
implements an interface. For example:
http.Handle("/", http.FileServer(<>))
will now give "http.Dir()" as a candidate since http.Dir is a named
string type that implements the required interface http.FileSystem.

In it previous implementation, tool.Main was meant to be called from

error to standard error and exit with a non-zero status (2).
It is also called recursively and in various test functions.
Exiting on an error makes testing difficult, unnecessarily.
This change breaks the functionality into to parts: an outer
tool.MustMain() that is intended to be called by main() functions and
an inner Main that is used by MustMain() and by test functions.

We were recursing infinitely in cases like this:

There were three things that came together to cause this:
1. We recently starting recursively fixing broken go/defer statements.
2. In this case we were failing to swap in the correct ast.Node in for
the *ast.BadStmt because we were only looking
for *ast.BlockStmt (and *ast.CaseStmt has no block).
3. After 2), we weren't returning an error so the fix() code thought
it should recurse.
Fix 2) by using reflection to swap AST nodes in a generic way. Perhaps
a bit overkill in this case, but I happened to have already written
this for an upcoming change, so I just pulled it in to fix this bug.
Fix 3) by returning an error if we fail to swap the AST nodes.

Now we will offer function literal completions when we know the
expected type is a function. For example:
sort.Slice(someSlice, <>)
will offer the completion "func(...) {}" which if selected will
insert:
func(i, j int) bool {<>}
I opted to use an abbreviated label "func(...) {}" because function
signatures can be quite long/verbose with all the type names in there.
The only interesting challenge is how to handle signatures that don't
name the parameters. For example,
func HandleFunc(pattern string, handler func(ResponseWriter, *Request)) {
does not name the "ResponseWriter" and "Request" parameters. I went
with a minimal effort approach where we try abbreviating the type
names, so the literal completion item for "handler" would look like:
func(<rw> ResponseWriter, <r> *Request) {<>}
where <> denote placeholders. The user can tab through quickly if they
like the abbreviations, otherwise they can rename them.
For unnamed types or if the abbreviation would duplicate a previous
abbreviation, we fall back to "_" as the parameter name. The user will
have to rename the parameter before they can use it.
One side effect of this is that we cannot support function literal
completions with unnamed parameters unless the user has enabled
snippet placeholders.

Add support for literal completion candidates such as "[]int{}" or

existing type matching logic, so, for example, if the expected type is
an interface, we will suggest literal candidates that implement the
interface.
The literal candidates have a lower score than normal matching
candidates, so they shouldn't be disruptive in cases where you don't
want a literal candidate.
This commit adds support for slice, array, struct, map, and channel
literal candidates since they are pretty similar. Functions will be

- Reduce our budget check interval from 1000 candidates to 100

Go 1.13 introduced a module in GOROOT/src. That triggered goimports to
think that it was an invalid module, usable only as a replace target,
because its declared module path "std" didn't match its apparent path
"src". The stdlib is always in scope, so skip the needs-replace check
for GOROOT.

In api/*.txt, interface declarations are represented with lines like:
pkg container/heap, type Interface interface { Len, Less, Pop, Push, Swap }
or, when they have no exported methods:
pkg go/ast, type Expr interface, unexported methods
The latter form confuses mkstdlib into thinking that it's a method
because of the extra comma, and then it skips the interface entirely.
Running this program is a matter of seconds once per release, so rather
than trying to fix the optimization, just remove it. The parsing logic
doesn't care about the extra lines.

Now when a file is deleted we force the file's packages to refresh
go/packages metadata, and kick off diagnostics.
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

Change it to not downrank builtins. In my testing with this change,

think this is because the "natural" order of completion items puts

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

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.

The `files` slice is used twice. First it's used to get all results from `ph.Parse`, and then it's reused to filter all `nil` values (which may have been returned by the `ph.Parse` method).
After the loop to "filter" out all the `nil` values, we also need to strip the remaining values.
I also changed the ordering so that we first check the errors and
only then perform this loop. That way the code will return earlier
when the context was canceled.
Partially fixes#33531 by prevention the panic reported in that issue.

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
