Heschi Kreinick 2b84a066b2 internal/lsp: use gocommand.Invocation more
We pass around verb/args/wd in many places. Bundle them up as an
Invocation instead. goCommandInvocation now updates and returns an input
Invocation.

packages.Config is conceptually an extra layer of parsing and
type-checking on top of a go list invocation. It doesn't make sense for
us to construct the latter using the former. A later CL will construct
the Config in terms of the Invocation; for now duplicate a bit of logic.

Use the environment in the cache key for various module operations
rather than the Config hash. I'm not sure either is fully correct but I
think the environment captures everything that's likely to matter. This
way we don't need Configs in those functions at all.

Rob Findley 0b86805daf internal/lsp: finish work when synchronous commands complete
Synchronous commands were bypassing the logic to handle the command
error an publish a final workDoneProgressEnd message. Push this logic
down into Server.runCommand.

Also, switch 'generate' to be synchronous, since this makes sense and
causes the synchronous path to be exercised in tests.

Finally, stop defaulting the command title to Command.Name. All Commands
should have Titles.

Rob Findley 1e23e48ab9 internal/lsp: improvements for command messages
When falling back to messages for progress reporting, don't try to
implement cancellation via ShowMessageCommand dialogs. They are an
imperfect solution, as the dialog stays open even after the command
completed. Also, among the LSP clients that don't support workDone
reporting, I suspect many also don't support ShowMessageCommand (for
example, govim), so the audience for this feature is probably quite
small.

Just remove it, and instead show a (non-cancellable) message. If clients
want cancellation, workDone progress support is the way to provide it.

Also remove a redundant message on go-generate success, and attach logs
when tests fail. Without logs on failure, I find that the test command
is not very useful. I tested a bit with very verbose test output, and
both VS Code and coc.nvim handled it gracefully.

Finally, fix a bug causing benchmarks not to be run.

Rob Findley ed71c57206 internal/lsp: consolidate progress reporting
This change contains several improvements for progress reporting:

 + Consolidate the 'progressWriter' interface into the workDone
   interface.  Now all progress reporting should use workDone, and the
   workDoneWriter struct is just an io.Writer adapter on top of
   workDone.
 + Factor out the pattern of progress reporting, and use for all
   asynchronous commands.
 + Make several commands that were previously synchronous async.
 + Add a test for cancellation when the WorkDone API is not supported.
 + Always report workdone progress using a detached context.
 + Update 'run tests' to use the -v option, and merge stderr and stdout,
   to increase the amount of information reported.
 + Since $/progress reporting is now always run with a detached context,
   the 'NoOutstandingWork' expectation should now behave correctly. Use
   it in a few places.

A follow-up CL will improve the messages reported on command completion.

Pontus Leitzler cf83efe03c internal/lsp: return err if ExecuteCommand prerequisites aren't met
Some Commands require that the buffer is saved before running them (i.e.
generate, test and toggle details). If the buffer isn't saved gopls
sends a ShowMessage request to the client. Before this change it
did not return any error from the ExecuteCommand request itself (unless
ShowMessage failed).

A progress token can be provided by the client as a part of the
ExecuteCommand request, and that is, according to the LSP spec one way
to start a WorkDoneProgress. At this point the client expects
that gopls send progress updates.

With this change, ExecuteCommand now return an error if the buffer
isn't saved, so that the client know that it shouldn't expect any
progress updates with this specific token.

Heschi Kreinick c1903db4db internal/memoize: switch from GC-driven to explicit deletion
The GC-based cache has given us a number of problems. First, memory
leaks driven by reference cycles: the Go runtime cannot collect cycles
involving finalizers, which prevents us from writing natural code in
Bind callbacks. If we screw it up, we get a mysterious leak that takes a
long time to track down. Second, the behavior is generally mysterious;
it's hard to predict how long a value lasts, and harder to tell if a
value being live is a bug. Third, we think that it may be interacting
poorly with the GC, resulting in unnecessary memory usage.

The structure of the values we put in the cache is not actually that
complicated -- there are only 5 significant types: parse, typecheck,
analyze, parse mod, and analyze mod. Managing them manually should not
be conceptually difficult, and in fact we already do most of the work
in (*snapshot).clone.

In this CL the cache adds the concept of "generations", which function
as reference counts on cache entries. Entries are still global and
shared across generations, but will be explicitly deleted once no
generations refer to them. The idea is that each snapshot is a new
generation, and can inherit entries from the previous snapshot or leave
them behind to be deleted.

One obvious risk of this scheme is that we'll leave dangling references
to values without actually inheriting them across generations. To
prevent that, getting a value requires passing in the generation at
which it's being read, and an error will be returned if that generation
is dead.

Heschi Kreinick 412b8bda49 internal/lsp/cache: ref-count snapshots
To manually collect cache entries, we need to know when a snapshot is
idle. Add a reference count in the form of a WaitGroup and keep track of
its uses. The pattern is that any time a snapshot is returned, it comes
with a release function that decrements the ref count.

Almost all uses of a snapshot originate in a user-facing request,
handled in beginFileRequest. There it's mostly an exercise in passing
Snapshots around instead of Views.

In the other places I took the path of least resistance. For file
modifications I tried to minimize the amount of code that needed to deal
with snapshots. For diagnostics I just acquired the snapshot at the
diagnostics call.

I'm not sure how the regtest didn't catch this - is it possible that
it could unmarshal a single string a slice of string? Either way, I'd
like to get the fix in quicker - I'll try to add more regtests for this
later.

Also, validate the upgrade results more thoroughly.

Rebecca Stambler 9267083701 internal/lsp: support refactor.extract through commands
The logic for extracting a function is quite signficant, and the code
is expensive enough that we should only call it when requested by the
user. This means that we should support extracting through a command
rather than text edits in the code action.

To that end, we create a new struct for commands. Features like extract
variable and extract function can supply functions to determine if they
are relevant to the given range, and if so, to generate their text
edits. source.Analyzers now point to Commands, rather than
SuggestedFixFuncs. The "canExtractVariable" and "canExtractFunction"
functions still need improvements, but I think that can be done in a
follow-up.

Rebecca Stambler 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).

Rebecca Stambler 5ea363182e internal/lsp: change the way that we pass arguments to command
Our approach to commands and their arguments has been ad-hoc until this
point. This CL creates a standard way of defining and passing the
arguments to different commands. The arguments to a command are now
json.RawMessages, so that we don't have to double encode. This also
allows us to check the expected number of arguments without defining
a struct for every command.

Rebecca Stambler 4025ed8474 internal/lsp: move fillstruct suggested fixes out of analysis
This change moves the suggested fixes logic for fillstruct out of the
analysis and into internal/lsp/source. This logic is then used as part
of a new fillstruct command. This command is returned along with the
code action results, to be executed only when the user accepts the code
action.

This led to a number of changes to testing. The suggested fix tests in
internal/lsp doesn't support executing commands, so we skip them. The
suggested fix tests in internal/lsp/source are changed to call
fillstruct directly. A new regtest is added to check the command
execution, which led to a few regtest changes.

Also, remove the `go mod tidy` code action, as it's made redundant by
the existence of the suggested fixes coming from internal/lsp/mod.

Heschi Kreinick ecd3fc4348 internal/lsp: read files eagerly
We use file identities pervasively throughout gopls. Prior to this
change, the identity is the modification date of an unopened file, or
the hash of an opened file. That means that opening a file changes its
identity, which causes unnecessary churn in the cache.

Unfortunately, there isn't an easy way to fix this. Changing the
cache key to something else, such as the modification time, means that
we won't unify cache entries if a change is made and then undone. The
approach here is to read files eagerly in GetFile, so that we know their
hashes immediately. That resolves the churn, but means that we do a ton
of file IO at startup.

Incidental changes:

Remove the FileSystem interface; there was only one implementation and
it added a fair amount of cruft. We have many other places that assume
os.Stat and such work.

Add direct accessors to FileHandle for URI, Kind, and Version. Most uses
of (FileHandle).Identity were for stuff that we derive solely from the
URI, and this helped me disentangle them. It is a *ton* of churn,
though. I can revert it if you want.

This required the addition only of the ability to view the sessions open
on a cache and exposing the unique identifier for all the objects, both
of which are useful and reasonable things to have in the API anyway.

Some code lenses may be undesirable for certain users or editors -- for
example a code lens that runs tests, when VSCode already supports this
functionality outside of the LSP. To handle such situations, support
configuring code lenses via a new 'codelens' gopls option.

Add support for code lens in regtests, and use this to test the new
configuration. To achieve this, thread through a new 'EditorConfig' type
that configures the fake editor's LSP session. It made sense to move the
test Env overlay onto this config object as well.

While looking at them, document some types in source.Options.

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
