b793a1359e internal/lsp: add outgoing calls call hierarchy
* Adds outgoing calls call hierarchy for function declarations to gopls. Returns all call ranges and call items for functions/literals being called.
* Adds tests for outgoing call.
* Updates cmd to account for call ranges and call items being in different files for outgoing calls.
* Updates prepare call hierarchy to return declaration as root instead of cursor position.

Example:
Example shows https://github.com/golang/tools/blob/master/internal/lsp/source/call_hierarchy.go

Show Call Hierarchy View: https://imgur.com/a/DA5vc6l
Peek Call Hierarchy View: https://imgur.com/a/fuiG0Be

Note:
* While incoming calls for a function defined in an interface return references to that function, outgoing calls don't return anything since we don't know what implementation to return outgoing calls for.* Outgoing calls to function literals show as variable name used to define the literal, compared to <scope>.func() for incoming calls.

1365742343 internal/lsp: add incoming calls hierarchy to gopls
* Adds incoming calls hierarchy to gopls. Returns function declarations/function literals/files enclosing the call/s to the function being inpected.
* Updates cmd to show ranges where calls to function in consideration are made by the caller.
* Added tests for incoming calls.

Example:

Note:
* Function literals show up as <scope>.func() in call hierarchy since they don't have a name. Here scope is either the function enclosing the literal or a file for top level declarations
* Top level calls (calls not inside a function, ex: to initialize exported variables) show up as the file name
* Clicking on an item shows the the range where a call is made in the scope

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.

110bd3ba6b internal/lsp: make function extraction smarter
In the previous implementation, the extracted function would
sometimes include superfluous parameters and return values. It
might also  unnecessarily initialize variables. This CL introduces
3 rules to limit this behavior. (1) a variable is not passed as a
parameter to the extracted function if its first use within the
function is its own redefinition. (2) a variable is not returned
from the extracted function if its first use after the function is its
own redefinition. (3) when possible, we redefine variables in the call
expression to the extracted function.

c9619e8fac internal/lsp: separate LSP files from FS files
FileHandle currently includes LSP-level information about Version and
Session. That's dangerous, because the cache operates in terms of
URIs and content only -- we explicitly want to share results across
sessions and versions if they happen to be the same.

Split the LSP information into separate types, VersionedFileHandle and
VersionedFileIdentity.

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.

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.

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).

80cb79702c internal/lsp: don't publish duplicate diagnostics in one report
CL 242579 changed the mechanism of reporting diagnostics so that we now
combine reports from multiple sources. Previously, we overwrote existing
diagnostics if new ones were reported. This was fine because
source.Diagnostics generated all of the diagnostics for Go files, and
mod.Diagnostics generated all of the diagnostics for go.mod files.

Now, we combine diagnostics from both sources -- mod.Diagnostics can
generate reports for Go files. We may get duplicate reports for packages
with test variants, so now, we check for those and dedupe.

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.

e48fac377d internal/lsp: change workspace symbols to use session config for matcher
WorkspaceSymbols matches symbols across views using the given query,
according to the matcher Matcher.

The workspace symbol method is defined in the spec as follows:

 > The workspace symbol request is sent from the client to the server to
 > list project-wide symbols matching the query string.

It is unclear what "project-wide" means here, but given the parameters
of workspace/symbol do not include any workspace identifier, then it has
to be assumed that "project-wide" means "across all workspaces".  Hence
why WorkspaceSymbols receives the views []View.

However, it then becomes unclear what it would mean to call
WorkspaceSymbols with a different configured Matcher per View.

Therefore we assume that Session level configuration will define the
Matcher to be used for the WorkspaceSymbols method.

As part of this change we also tidy up lsp_test.go and source_test.go to
remove some repetition.

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.

3304cfb00f internal/lsp: temporarily disable type error analyzers by default
If we release gopls/v0.4.0 soon, we should keep these new analyzers off
by default. They were just merged, so they haven't been used enough to
be enabled, I think. We'll turn them on by default for gopls/v0.5.0.

Also, ended up creating a helper function to check if analysis has been
abled (which fixed a small bug in FindAnalysisError), and another helper
function to enable all analyses for testing purposes.

As a result, these older lsp clients need to recieve []protocol.SymbolInformation rather than []protocol.DocumentSymbol. This change required some changes to internal/lsp/cmd to handle not knowing which type it is receiving, this required manual parsing inside of cmd/symbols.go.

e02f5847d1 internal/lsp/debug: move all debug state onto the Instance
For testability, and to support the exchange of debug information across
Forwarder and server, it is helpful to encapsulate all debug information
on the instance object.

This CL moves all state in the debug package into a new 'State' type,
that is added as a field on the debug.Instance. While doing so, common
functionality for object collections is factored out into the objset
helper type.

Also add two new debug object types: Client and Server. These aren't yet
used, but will be in a later CL (and frankly it was easier to leave them
in this CL than to more carefully rewrite history...).

Diagnostics runs cannot be canceled until they finish a package. If a

To avoid that, only allow one diagnostics run at a time. We can change
the limit later if we want.
