The two codelenses that are attached to the module statement are
'Run go mod tidy' and 'Create vendor directory'. In a 'go.mod' file
without any required modules, the only codelens that shows up is
the 'Create vendor directory'. With no required modules, there is nothing
to vendor, but 'Run go mod tidy' may actually clean up the go.mod and go.sum,
so this is the codelens we want to appear.

Type error analyzers can be viewed as enhancing type errors, rather
than analyzers in their own right. Create a source.DiagnosePackage
function that combines the list/parse/typecheck diagnostics with type
error analyzers. This allows us to remove some special cases from the
analysis path, and is a first step in removing all the special
handling for analysis quick fixes.
Along the way:
Pass pointers to source.Analyzer after I spent half an hour chasing a
loop capture bug. Spend a further 2-3 hours chasing slowdown in the
command tests as a result.
Move Unnecessary tag generation into diagnostic creation rather than
as a mutating post-processing step that required cloning diagnostics.

This involved several steps:
+ Switch the command dispatch in internal/lsp/command.go to go through
the command package. This means that all commands must now use the new
signature.
+ Update commandHandler to use the new command signatures.
+ Fix some errors discovered in the command interface now that we're
actually using it.
+ Regenerate bindings.
+ Update all code lens and suggested fixes to new the new command
constructors.
+ Generate values in the command package to hold command names and the
full set of commands, so that they may be referenced by name.
+ Update any references to command names to use the command package.
+ Delete command metadata from the source package. Rename command.go to
fix.go.
+ Update lsp tests to execute commands directly rather than use an
internal API. This involved a bit of hackery to collect the edits.
+ Update document generation to use command metadata. Documenting the
arguments is left to a later CL.
+ Various small fixes related to the above.
This change is intended to be invisible to users. We have changed the
command signatures, but have not (previously) committed to backwards
compatibility for commands. Notably, the gopls.test and gopls.gc_details
signatures are preserved, as these are the two cases where we are aware
of LSP clients calling them directly, not from a code lens or
diagnostic.

The only thing that the mod tidy diagnostics use the network for is
adding dependencies, and we already have quick fixes for those. The one
exception is the case covered by TestBadlyVersionedModule, a dependency
that fails to declare one of its own dependencies and therefore requires
an indirect dependency in the workspace module. That only triggers an
error on the dependency's import statement, which the user will never
see.
Fortunately, the go command does expose these problems in the DepsErrors
field of the list response. Add an internal API to access that, and turn
it into diagnostics on both the file and the controlling go.mod.
Refactor the go get diagnostic generation so that it applies to both
modules and packages.

Collapse Diagnostic.Kind, Source, and Category into just Source. Remove
code that converted from Diagnostic to Diagnostic. Notes on the changes
I had to make along the way:
- We used to use Kind to determine Severity. Set Severity when the
Diagnostic is created instead.
- Use constants for Source as much as possible -- we still need to use
Analyzer.Name for analysis diagnostics. It would be nice to break that
dependency so that Source was totally opaque, but that's a separate
issue.
- Introduce a new Source for gc_details, "optimizer details". It was "go
compiler" previously.
- Some of the assignments are a little arbitrary. Is inconsistent
vendoring really a "go list" error?
- GetTypeCheckDiagnostics had code to cope with diagnostics that had no
URI associated with them. We now spread such diagnostics to all files
when they are generated.
- Analyze modifies Diagnostics by adding a Tag to them. That means it
has to own them, so I had it clone them. I would like to push that logic
down to the diagnostics, per the TODO, but that's another CL.
And some observations:
- It's obviously tempting to combine DiagnosticSource and
diagnosticSource, but they mean very different things. I'm open to a
better name for one or the other.

Some other smaller changes are made to account for these changes. One
change is that we may report multiple *source.Errors, with the
assumption that duplicate diagnostics will be caught by the diagnostic
caching. Also, any `go list` error message that ends with "to add it" is
now considered an error that gets the "add dependency" suggested fix.

A concern would be that the user wouldn't know why their code wasn't

notice the error message. At least, other features would continue
working. The best fix will definitely be the fix for the panic, but that

For users with poor network connections, go command invocations that
access the network may hang up for long periods of time. Even for
users with good network connections, accessing proxy.golang.org or
github can take a few seconds, which is a long time to lock up an
editor.
Disable network access via GOPROXY=off when running most go commands.
There are two notable exceptions. First, the initial workspace load is
allowed, though subsequent loads are not. My reasoning is that if the
user is opening a project they've just downloaded, they probably expect
to fetch its dependencies. (Also, it's convenient to keep the regtests
going.) The second is the go mod tidy diagnostics, which I hope to
address in a later change. All the other commands that access the
network are at the user's request.
When the workspace load fails due to a dependency that hasn't been
downloaded, we present a quick fix on the go.mod line to do so. The only
way that happens is if there's a manual modification to the go.mod file,
since all of the other quick fixes will do the download. So I don't
think there's a need to present the fix anywhere else.

The tidy and upgrade code lenses first run the go command they
represent, then show the lens if there are changes to be made. While
this makes for a cleaner user experience, it also means that we're
running a go command that hits the network in a synchronous code lens
call. That's risky if the user is on a slow network connection.
Removing the call does represent a change, possibly a regression, in UX.
However, we already felt that the presentation of the upgrade option on
each dependency line was too noisy. Therefore the only remaining benefit
is that the lenses only appear when they have something to do. We've
decided that's not sufficient justification. Remove the calls.
We may recreate them as diagnostics in the future, so I've left
ModUpgrade around. (ModTidy is still used by diagnostics.)

A few of the view's methods are moved to the snapshot, as they will
soon rely on the snapshot's modules field. Some dead code is also
deleted.
We now populate the snapshot's modules field even when
ExperimentalWorkspaceModule is not true, but we stop looking for modules
after searching the view's root.

gopls has many settings. We want to automatically generate
documentation, and we want to allow clients to perform their own
validation if they so desire.
Using all three of AST, type information, and reflection, generate a
JSON description of the settings and their default values. Add a gopls
command that prints it. Add a documentation generator that uses it to
write settings.md.
I assumed that everything not explicitly documented was experimental,
and moved it into that section. I also moved expandWorkspaceToModule to
experimental; I hope it's not long for this world, personally.
Along the way, rename many fields, make the enum matching case
insensitive, and add a stringer call so that the defaults print nicely.

FileHandle currently includes LSP-level information about Version and

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.

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.

Due to the runtime's inability to collect cycles involving finalizers,
we can't close over handles in memoize.Functions without causing memory
leaks. Up until now we've dealt with that by closing over all the bits
of the snapshot that we want, but it distorts the design of all the code
used in the Functions.
We can solve the problem another way: instead of closing over the
snapshot/view, we can force the caller to pass it in. This is somewhat
scary: there is no requirement that the argument matches the data that
we're working with. But the reality is that this is not a new problem:
the Function used to calculate a cache value is not necessarily the one
that the caller expects. As long as the cache key fully identifies all
the inputs to the Function, the output should be correct. And since the
caller used the snapshot/view to calculate that cache key, it should
always be safe to pass in that snapshot/view. If it's not, then we
already had a bug.
The Arg type in memoize is clumsy, but I thought it would be nice to
have at least a little bit of type safety. I'm open to suggestions.

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.
