37a045f3b9 internal/lsp: move undeclaredname suggested fix out of analysis
This CL is a follow-up from CL 241983. I didn't realize that the
undeclaredname analysis was also using the go/printer.Fprint trick,
which we decided was both incorrect and inefficient. This CL does
approximately the same things as CL 241983, with a few changes to make
the approach more general.

source.Analyzer now has a field to indicate if its suggested fix needs
to be computed separately, and that is used to determine which
code actions get commands. We also make helper functions to map
analyses to their commands.

I figured out a neater way to test suggested fixes in this CL, so I
reversed the move to source_test back to lsp_test (which was the right
place all along).

6d307edf52 internal/lsp: support extract function
Extract function is a code action, similar to extract variable. After
highlighting a selection, if valid, the lightbulb appears to trigger
extraction. The current implementation does not allow users to
extract selections with a return statement.

f2c07d7d8e internal/lsp/lsprpc: improvements to daemon logging
The gopls daemon had different default logging behavior than the sidecar
gopls: by default, the daemon was started with -logfile=auto.
Additionally, because most logs are reflected back to the forwarder, the
actual daemon logs have very little (if any) information.

This means that if you simply start gopls with -remote=auto, you'll get
a single logfile named /tmp/gopls-<pid>.log, which is mostly empty. This
is not a delightful experience.

Fix this via several improvements:
 + Log lifecycle events in the Daemon, to give the log a purpose.
 + Give the daemon a new default log location:
   /tmp/gopls-daemon-<pid>.log.
 + Don't pass -logfile=auto to the daemon by default.

Fixes golang/go#40105

e31b568ad1 internal/lsp: plumb fillstruct through analysis
Now that fillstruct is an analyzer, we can simplify the code that calls
it in code_action.go. We introduce a new class of analyzer --
convenience analyzers, which are closer to commands. These represent
suggestions that won't necessarily improve the quality or correctness of
your code, but they offer small helper functions for the user.

This CL also combines the refactor rewrite tests with the suggested fix
tests, since they are effectively the same.

For now, we only support convenience analyzers when a code action was
requested on the same line as the fix. I'm not sure how to otherwise
handle this without bothering the user with unnecessary diagnostics.

other uses of Matcher, e.g. completion.

Which tails the daemon logs for the current gopls binary version.

4d14fc9c00 internal/lsp: add type error fixes to existing diagnostics
This change is the first step in handling golang/go#38136. Instead of
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
look-up.

Also, ended up creating a helper function to check if analysis has been

17a19b5fe7 internal/lsp/cmd: add a flag to disable telemetry
govim integration tests (and probably some real user sessions) are
broken because telemetry metrics are not threadsafe, resulting in an
index out of range panic.

Fix this by adding a flag (labeled temporary) to disable telemetry
export.

Also temporarily update govim to master to pick up some fixes, and run
only the -short tests to avoid timeouts.

In addition, currently using the same connection despite different

daemon mode, daemon.md is updated to reflect the new features and to
remove some of the experimental warnings. Similarly the `-remote` flag

The feature still needs more usage, but it shouldn't be considered
experimental anymore.

30fd94b347 internal/lsp/lsprpc: expose configuration for auto-started daemon
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.

This can be used even if the debug server is not running, which will

As a result, these older lsp clients need to recieve []protocol.SymbolInformation rather than []protocol.DocumentSymbol.

de023d59a5 internal/lsp/protocol: unmarshal to pointers when dispatching requests
With #34111, we are forwarding the LSP from one gopls instance to
another. This exposed an asymmetry in our LSP dispatching: for both
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
wouldn't be surprised if we discover more NPEs later on, but I still
think this is the right change to make.

9ffc0ab4ef internal/jsonrpc2: add an idle timeout for stream serving
When running gopls against an automatically started remote instance, we
want the lifecycle of the remote to be detached from that of its
clients, so that it doesn't shut down while clients are still connected.
On the other hand, a gopls process can consume significant resources, so
we don't want it to remain when there are no more connected clients.

The jsonrpc2 package is updated to support the concept of idle timeout:
a duration after which the server is shut down when there are no
connected clients. This is exposed in the gopls serve command via the
-listen.timeout flag.

Most users will not want to manage their own gopls instance, but may

the -remote flag similarly to UDS (i.e. -remote="auto;uniqueid"). In
this mode, the actual remote address will be resolved automatically
based on the executing environment and unique identifier, and the remote
server will be started if it isn't already running.
