package relevance to rank the probably-more-relevant typed members
higher. However, there are some unrelated score penalties that can

up being ranked higher. Fix by increasing the relevance coefficient so
the relevance score overpowers other less important scoring

We had previously not been generating documentation on hover for

Throughout, we make the assumption that only one file in a package will
have the documentation for the package. go/doc just appends
documentation as it sees it. We may be able to do better by checking for
a "Package ..." but that still is not guaranteed. Not sure what the

A common problem when writing regtests is that if you have an error in
your expectations, you must wait until the regtest times out to see what
went wrong.
With the integration of additional progress reporting in the LSP server,
we know when diagnostic work should have been completed, and we should
be able to fail tests early once we know that our diagnostic
expectations will never be met.
This CL adds a new OnceMet Expectation, which combines two expecations:
the first is a precondition that must be met before checking the second.
The second is an arbitrary expectation, but is translated as follows:
once the precondition is met, the second condition is checked and any
Unmet verdicts are translated into Unmeetable.

In order for regtests to wait until file diagnostics are complete,
instrument diagnostics with verbose WorkDone reporting. In order for
this to be granular enough for use, the modification source needed to be
threaded through to the didModifyFiles function (which is where the
diagnostic goroutine is spun off).
A new expectation is added: CompletedWork, to allow specifying that a
specific work item has been completed. The problem with using
NoOutstandingWork was that it required a continuous chain of work to
prevent the regtest from succeeding when the bug was present, meaning
that by the time we have sent the didChange notification successfully
the server must have started work on its behalf. This was inherently
racy, and too tricky to get right.
Additionally, a couple bugs are fixed:
- EmptyDiagnostics is corrected to account for the case where we have
received zero diagnostics for a given file.
- A deadlock is fixed in Await when expectations are immediately met.

Due to the asynchronous and non-transactional nature of the LSP, writing
regtests requires waiting for certain conditions to be met in the client
editor. To this point, the only type of condition for which we supported
waiting was the presence of diagnostic messages, but we can in principle
wait for anything that is triggered by a server notification.
This change generalizes the notion of expectations to also encompass log
messages. Doing this required expanding the value returned from checking
expectations to include a new "Unmeetable" verdict, to account for cases
where we know that a condition will never be met (for example if it is a
negative assertion). This may be useful for diagnostics as well.
A test is added to demonstrate these new expectations, where the initial
workspace load fails due to unfetchable dependencies.
Additionally, some helper flags are added to help debug regtests without
a code change, by allowing changing the test timeout, printing logs, and
printing goroutine profiles.

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).

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

Now it only uses the telemetry messages directly rather than the metric system.
This is much faster and more direct, and removes a blocker on improving the
metrics support.
Also fixes the fact that recieced and sent were the wrong way round before,
probably as an artifact of the old protocol logging code, and also removes
the bytes histogram which was a lie (it was a histogram of write sizes that
was presented as a histogram of message sizes)

One of the tricky things about asserting on conditions in regtests is
the asynchronous nature of LSP. For example, as the LSP client we cannot
be sure when we've received all diagnostics for a given file.
Currently, regtests are implemented by awaiting specific diagnostic
expectations. This means that if gopls generates diagnostics that do
not match those expectations, we can only time out the test.
Ideally, we would want to know that gopls is done generating all diagnostics
for the current file state. This is not possible without knowing the
status of diagnostics for. Barring this, we would want to know that
diagnostics are done for the current file version. Unfortunately, that
also is not possible, because a new version of file B can affect
diagnostics in file A.
So in lieu of this information, this CL exposes a few tools that can be
used to improve the experience of writing new regtests.
- A new expectation is added: AnyDiagnosticAtCurrentVersion, that is
satisfied if any diagnostics have been received for the current
buffer version.
- ExpectDiagnostics is added to Env, to help check whether the current
diagnostics matches expectations.

doing that for package names, because the first two reasons aren't very
relevant. But the third still is -- loaded packages are a pretty good
approximation for in module scope, etc.
With this change we do package names the same as members, so relevance
should be about as good. Not perfect, but nobody's complained much yet.

We no longer need the event.Query method (or the event type)
We now exclusivley use Key as the identity, and no longer have a

This removes some confusion that was causing the same key through

Expressing regtests in terms of textual coordinates is hard to read: the
reader ends up counting lines and characters to understand the text edit
or assertion.
To address, this, add two new functions for fake.Editor: RegexpSearch
and RegexpReplace, as well as a symmetric RegexpSearch function for
workspace files and wrappers for regtext.Env.
This allows expressing edits as well as buffer locations in terms of
easily scannable regexps.
An alternative solution to this problem is to integrate markers ala
packagestest. I tried this, but it ended up being cumbersome to
implement and less usable than regexps, due to the static nature of
markers: after the buffer has been edited all markers must be
updated.

func (f foo) Field() int { return f.field }
func (f foo) logic() {

Now at <> we prefer "field" over "Field()". Similarly:
type foo struct {

func (f foo) DoSomething() { }
func (f foo) doSomething() { }
func (f foo) logic() {
f.d<>

Now at <> we prefer "doSomething()" over "DoSomething()". All else
being equally, you normally want private objects over public objects
when the private objects are available.
The same logic is applied to deep completions so we prefer "c.foo.bar"
over "c.Foo().bar".

When searching for deep completions, we can end up enumerating struct
types' fields a lot. Optimize fieldSelections to reduce work:
- Wait until we see an embedded field before we create the "seen"
map.
- Use a callback style to iterate over the struct's fields rather than
returning a slice of fields.
- Change "seen" checking strategy back to track struct types rather
than each individual field.
Struct with 5 non-embedded fields:
name old time/op new time/op delta
Fields-16 293ns ± 1% 20ns ± 2% -93.13% (p=0.008 n=5+5)
name old alloc/op new alloc/op delta
Fields-16 120B ± 0% 0B -100.00% (p=0.008 n=5+5)
name old allocs/op new allocs/op delta
Fields-16 4.00 ± 0% 0.00 -100.00% (p=0.008 n=5+5)
Same struct but add an embedded struct with 2 fields:
name old time/op new time/op delta
Fields-16 389ns ± 1% 142ns ± 1% -63.53% (p=0.008 n=5+5)
name old alloc/op new alloc/op delta

Fields-16 4.00 ± 0% 2.00 ± 0% -50.00% (p=0.008 n=5+5)
I think the alloc/op went up because the "seen" map is no longer

it's probably not worth making things more complicated.

This commit will make the 'go generate' CodeLens command check the client
capabilities to use $/progress to report the progress of the command or otherwise
it will fallback to showing the message box already in place. The $/progress will
give you a play by play update while the message box shows only the beginning and
the end. The gopls logs will have all the details in either case.
Note that the $/progress is an LSP 3.15+ feature and not yet supported in all clients.

This CL gets code.ts to generate code for $/progress and

ProgressParams type which contains one of three new data types,
WorkDoneProgressBegin, WorkDonProgressEnd, WorkDoneProgressReport.
In addition, a *TextEdit is now generated for CompletionItem.TextEdit.
The substantive differences in code.ts are around line 451 and line
682. Everything else is whitespace caused by vscode formatting typescript
differently on different OSes.

This change adds support for recognizing a //go:generate directive
and offering a CodeLens that will then send a "generate" command to
the server to run "go generate" or "go generate ./...". Because
"go generate" can only be executed per package, there is no need to show
the CodeLens on top of every //go:generate comment. Therefore, only the
top directive will be considered.
The stdout/stderr of the go generate command will be piped to the logger
while stderr will also be sent to the editor as a window/showMessage
The user will only know when the process starts and when it ends so that they wouldn't
get bogged with a large number of message windows popping up. However, they can
check the logs for all the details.
If a user wants to cancel the "go generate" command, they will be able
to do so with a "Cancel" ActionItem that the server will offer to the client

Three new flags are added to the serve command, and threaded through to
the LSP forwarder:
-remote.listen.timeout: -listen.timeout for the auto-started daemon
-remote.debug: -debug for the auto-started daemon
-remote.logfile: -logfile for the auto-started daemon
As part of this change, no longer enable debugging the daemon by
default.
Notably none of this configuration affects serving, so modifying this
configuration has been chosen not to change the path to the automatic
daemon. In other words, this configuration has effect only for the
forwarder process that starts the daemon: all others will connect to the
daemon and inherit whatever configuration it had at startup. This should
be OK, because in the common case this configuration should be static
across all clients (e.g., many Vim sessions all sharing the same
.vimrc).
Exposing this configuration made the signature of lsprpc.NewForwarder
a bit hard to understand, so I decided to go ahead and switch to a
variadic options pattern for initializing both the Forwarder and
StreamServer, the latter just for consistency with the Forwarder.

Now we properly offer "case" and "default" keyword completion in cases
like:
switch {

}
First I had to add an AST fix for empty switch statements to move the
closing brace down. For example, say the user is completing:
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 {
}
Second I had to add logic to manually extract the completion prefix
inside empty switch statements, and finally some logic to offer (only)
"case" and "default" candidates in empty switch statements.

Now we offer an error-check-and-return completion candidate when
appropriate:
func myFunc() (int, error) {
f, err := os.Open("foo")
<>
}
offers the candidate:
if err != nil {
return 0, <err>
}
where <> denotes a placeholder so you can easily alter "err".
The completion will only be offered when:
1. The position is in a function that returns an error as final result
value, and
2. The statement preceding position is an assignment whose final LHS
value is an error.
The completion will contain zero values for the non-error return values
as necessary.
Using the above example, the completion will be offered after the user
has typed:
i
if
if err
Basically the candidate will be offered after every keystroke as the
user types "if err".

Offer "struct", "interface", "map", "chan", and "func" keywords when

Because "struct" and "interface" are more often used when declaring
named types, they get a higher score in type declarations. Otherwise,
"map", "chan" and "func" get a higher score.
I also got rid of the special keyword scoring. Now keywords just use
stdScore and highScore. This makes the interplay with other types of
candidates more predictable. Keywords are offered in pretty limited
contexts, so I don't think they will be annoying.
Finally, keyword candidate score is now to be scaled properly based on
how well they match the prefix. Previously they weren't penalized for
not matching well, so there were probably some situations where
keywords were ranked too high.

ClientDispatcher and ServerDispatcher, we unmarshal to non-nil response
structs. This means that when forwarding the LSP, we translate empty
JSON responses (corresponding to nil values) into the non-nil zero
value.
This causes problems for some editors, as reported in #37570. Fix it by
instead unmarshaling to a pointer.
This is, of course, a somewhat dangerous change. I fixed the one NPE
that occurred in tests, and have done some mild manual testing. I

started by the editor. By default, this puts it in the same process
group as the forwarder gopls.
Some editors (at least Vim) send SIGTERM to the process groups of
sidecar processes when exiting. This can cause the gopls daemon to
terminate, thereby losing state.
Rather than ignore SIGTERM (which is bound to be editor dependent
anyway), let's just put the gopls daemon in a separate session.

This means that tags also become cheap if there is no exporter and cleans up the
mess with how spans, tags and logs were related.
Also fixes the currently broken metrics that relied on the span tags.

We need to use the filename derived from the symbol information, not the
one from CompiledGoFiles, in case of cgo packages.
No tests because workspace symbols are entangled with document symbols,
and the latter doesn't work in cgo packages.

This change attaches a modTidyHandle to the snapshot instance and tries to reuse it as often as possible. It also modifies the modTidyKey to include the files that have not yet been saved. This was necessary because `go mod tidy` only runs using contents on disk.
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.

We no longer use the span as the core type of tracing, instead that is an
artifact of the exporter, and start and end tracing is just event based.
This both makes the interface normalized, and also means the null exporter case
is considerably cheaper in memory and cpu.

The Tagger interface allowed for specifying a key in a tag list and having the
value be aquired from the context automatically. It was almost never used, and
the alternative (using the key to get the value) is not that much more long
winded, so it was not holding it's own weight from a complexity persective alone
but the performance cost of having to use a list of interface rather than a list
of tags was very large. See the benchstat improvements below for the difference
it makes to both speed and memory usage, especially in the no exporter case.
