Heschi Kreinick cd1d0887dc internal/lsp/cache: trim more stuff in ParseExported mode
Despite the name, ParseExported only hollowed out declarations -- it
didn't actually drop any from the AST. This leaves a fair amount of
unexported crud behind. Unfortunately, there are a *lot* of ways to
expose an unexported declaration from an exported one, and it can be
done across files. Because of that, discarding unexported declarations
requires a lot of work.

This CL implements a decent attempt at pruning as much as possible from
the AST in ParseExported mode.

First, we analyze the AST of all the files in the package for exported
uses of unexported identifiers, iterating to a fixed point. Then, we
type check those ASTs. If there are missing identifiers (probably due to
a bug in the dependency analysis) we use those errors to re-parse. After
that we give up and fall back to the older, less effective trimming. The
pkg type changes slightly to accomodate the new control flow.

We have to analyze all the files at once because an unexported type
might be exposed in another file. Unfortunately, that means we can't
parse a single file at a time any more -- the result of parsing a file
depends on the result of parsing its siblings. To avoid cache
corruption, we have to do the parsing directly in type checking,
uncached.

This, in turn, required changes to the PosTo* functions. Previously,
they operated just on files, but a file name is no longer sufficient to
get a ParseExported AST. Change them to work on Packages instead. I
squeezed in a bit of refactoring while I was touching them.

Template support is controlled by the option 'experimentalTemplateSupport'
which defaults to false.

Most of the code is in a new 'template' package. Implemented are
semantic tokens, diagnostics, definitions, hover, and references,
and there is a stub for completions.

This code treats all the template files of a package together, so as
to follow cross-references.

Rob Findley 7a6108e9b2 internal/lsp: don't use ast.NewPackage to build builtin
ast.NewPackage mutates the input files, making it difficult to avoid
races with our caching model. I had avoided a race resulting from cache
handle cancellation, just to run into another race in multi-session
servers.

But there's no reason to use ast.NewPackage when we only have a single
file. We can just interrogate the file scope wherever needed.

Rob Findley 28c1392e35 internal/lsp: don't call PackagesForFile on builtin.go
Calling PackagesForFile on builtin.go loads is at a
command-line-arguments package, which has many type checking errors.

Add a new snapshot method IsBuiltin, which is used to avoid calling
PackagesForFile on builtin.go when diagnosing changed files or checking
for orphaned files. There may be other places where this should be used,
but this functionality can't reasonably be pushed down, as
PackagesForFile should always return something.

This exacerbated an existing race to building the builtin, because
ast.NewPackage unfortunately mutates the ast.File. Fix this by just
building the builtin package directly when building the handle. It
should be very fast.

Heschi Kreinick e435455aa1 internal/lsp: introduce MemoryMode
We still hear from users for whom gopls uses too much memory. My efforts
to reduce memory usage while maintaining functionality are proving
fruitless, so perhaps it's time to accept some functionality loss.

DegradeClosed MemoryMode typechecks all packages in ParseExported mode
unless they have a file open. This should dramatically reduce memory
usage in monorepo-style scenarious, where a ton of packages are in the
workspace and the user might plausibly want to edit any of them.
(Otherwise they should consider using directory filters.)

The cost is that features that work across multiple packages...won't.
Find references, for example, will only find uses in open packages or in
the exported declarations of closed packages.

The current implementation is a bit leaky; we keep the ParseFull
packages in memory even once all their files are closed. This is related
to a general failure on our part to drop unused packages from the
snapshot, so I'm not going to try to fix it here.

Updates golang/go#45457, golang/go#45363.

Heschi Kreinick 07295caad0 internal/lsp/cache: prune types.Info entries in slice literals
The type checker emits a TypeAndValue entry for (among other things)
every constant in a Go file. Normally, that cost is moderate. However,
in the case of a large slice literal, it can get out of control very
quickly. Imagine a code generator that creates a 2KB byte slice literal;
that's 2K TypeAndValue entries, each of which is considerably larger
than the 1-3 bytes for the source text.

Unfortunately, there are a number of such code generators. Notably,
there are such slice literals in proto code, e.g.
https://github.com/grpc/grpc-go/blob/master/examples/route_guide/routeguide/route_guide.pb.go#L360

This CL changes the type checking code to remove the TypeAndValue
entries for slice literals of basic types after the checker returns.
In the extreme case of https://github.com/googleapis/go-genproto, which
is nothing but protos, I see a ~40% drop in heap usage.

I believe this change is generally safe, but there's no way to guarantee
it. I don't think any editor features need to know the type or value of
an arbitrary slice element, but it is just barely possible that an
analyzer does.

Heschi Kreinick aa0c72341e internal/lsp/cache: get control of reloadOrphanedFiles
According to its comment, reloadOrphanedFiles is intended to work around
overlay bugs. But as of 1.16, there are no overlay bugs that we know of.
So what is it still doing?

Apparently, quite a bit, not much of it useful. Clean up as much as
possible.

- Files with no valid package declaration are ignored by the go command.
There's no point trying to reload them; stop.
- During metadata invalidation, we clear out all IDs for a file, even if
only one of its IDs is invalidated, e.g. when a test package is removed.
That leaves valid metadata for the non-test, so we don't refresh it in
the workspace reload, and only catch it as an orphan. It seems to me we
should only remove the invalidated ID.
- If the client incorrectly sends us a didOpen for a non-Go file, we
will attempt to load it as an orphaned file. Fix the regtest that did
that.
- TestEmptyGOPATHXTest_40825 set up an invalid GOPATH: you can't work in
GOPATH/src. However, it exists to test code that no longer exists, so
just delete it.

After this change, almost none of the regression tests trigger orphaned
file reloading. It's difficult/impractical to rule it out entirely
because some of them only appear racily. Since I intend to remove the
code path, I'm not too worried about more creeping in before I'm done.

The only useful case is multiple ad-hoc packages. Because we only
allow one "command-line-arguments" package in the workspace, if you
switch between two the old one becomes orphaned. I hope to work on that
soon.

Jay Conrod 50ca8d007d all: recognize new error from go command when no go.mod is found
This change fixes x/tools tests before CL 298650 lands. After that CL,
the go command reports a different error message when GO111MODULE=on
and it is invoked without a go.mod file (with a command that requires
a go.mod file). We plan to backport that change to 1.16.

For golang/go#44745

Heschi Kreinick 144d5ced6b internal/lsp: run type error analyzers as part of diagnostics
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.

Heschi Kreinick eb48d3f608 internal/lsp/cache: refactor diagnostic suppression
In typeCheckDiagnostics, we have logic to suppress go list and type
checking errors based on the presence of other errors. Nobody seems to
know why the logic is exactly what it is, and suppressing list errors
means that bad //go:embed patterns don't show up.

Intuitively, it makes sense to me that we don't want to type check if
listing or parsing fails: list errors mean that whole files may be
missing, and parsing errors may wipe out arbitrary chunks of files.
There's little point reporting errors from type checking that. However,
list errors and parse errors should be mostly orthogonal: go list
parses very little of the file and in practice only reports errors
parsing the package statement. So, at least for now, we report both
parse and list errors, and stop there if there are any.

Finally, move the suppression logic to the actual typeCheck function
that generates the diagnostics. typeCheckDiagnostics is the primary
consumer, but I think it's better to do the suppression at the source.

Because we are now showing list errors, and they are prone to getting
stuck due to bad overlay support, a couple of tests now require 1.16.

Due to misuse of the expandErrors function, when we encountered a

one, then return both it and all its secondaries individually. That
makes for a strange user experience where you get one complete error and
N-1 incomplete ones.

Instead, create a copy of the complete error for each secondary error,
moving the copy to the location of the secondary error and adding a bit
to the text to (hopefully) clarify what's going on.

Yuki Ito 0e232fa9c3 gopls: add scheme to CodeDescription.href
### gopls

- Add `https` scheme to `CodeDescription.href`

According to the [LSP specification](https://microsoft.github.io/language-server-protocol/specification#diagnostic), `CodeDescription.href` must be [URI type](https://microsoft.github.io/language-server-protocol/specification#uri). As described in the [RFC](https://tools.ietf.org/html/rfc3986#section-3), the scheme is required for URI:

> The scheme and path components are required, though the path may be empty (no characters).

Current `gopls` does not add the scheme to `CodeDescription.href`, and this results in some LSP clients ([at least this client](https://github.com/autozimu/LanguageClient-neovim)) which are strictly validating the URI format to be failed to populate diagnostics.

Heschi Kreinick 1e7abacf3b internal/lsp: refactor go command error handling
Our handling of go command errors was cobbled together, leading to
unexpected gaps and duplication. Refactor it to be more coherent.

Our goal is to turn every go command error into a diagnostic in the
relevant location. The errors don't contain error positions, so we have
to guess where they belong using the module names mentioned in the
error. If we can't find any reference to those modules, we are forced to
add diagnostics to all go.mod files.

I may have destroyed the intent of TestMultiModule_OneBrokenModule but
I'm not sure what to do about it.

Some cleanup along the way:
- Stop parsing modfile.Parse error text: it returns structured errors
and we can just use them.
- Return CriticalErrors from awaitLoadedAllErrors, and do error
extraction lower in the stack. This prevents a ridiculous situation
where initialize formed a CriticalError, then awaitLoadedAllErrors
returned just its MainError, and then GetCriticalError parsed out
a new CriticalError from the MainError we got from a CriticalError.
- In initialize, return modDiagnostics even if load succeeds: we are
missing packages and should not silently fail, I think?
- During testing I tripped over ApplyQuickFixes' willingness to not
actually do anything, so I made that an error.

Fixes golang/go#44132.
I may also have fixed golang/go#44204 but I haven't checked.

Rob Findley 8aef11fa67 internal/lsp: switch to the new command API
Fully switch to the new generated command API, and remove the old
dynamic command configuration.

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.

To properly complete at <>, we need to perform two fixes. We must

to deal with the incomplete "if" block. Previously we stopped at one
fix, but now we allow for up to 10. I added a limit because I am
afraid there are cases where we could get stuck trying to apply the

Also, drive-by set isIncomplete=true when we return early in

Heschi Kreinick 513be0a9d2 internal/lsp/cache: disable network for mod tidy diagnostics
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.

Heschi Kreinick e7dfe0279f internal/lsp: remove redundant fields/code after source.Error deletion
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.

Heschi Kreinick 51ce8377eb internal/lsp: remove the source.Error type
source.Error and source.Diagnostic are almost identical types, used
arbitrarily in different parts of the code. This CL is the first step in
cleaning up that redundancy: it deletes the source.Error type.

To do that, I added the fields from source.Error to source.Diagnostic,
and made absolutely no other semantic code changes -- I just renamed
things that were named Error to Diagnostic. With only aesthetic concerns
in play, I hope this CL will be easy to review. The next CL will clean
up all the stupid-looking code that converts a Diagnostic to a
Diagnostic, etc.

pjw c3402e3c42 internal/lsp: update to latest version of LSP protocol
The Typescript source is still at version 3.16, but there are new
requests, more detailed client capabilities, and an attempt to be
more specific about ranges of number in the Typescript code.

Vscode defines types integer and uinteger (32-bit signed and unsigned),
so the Go code now uses int32 and uint32.

They've changed the use of TextDocument, so version information is sometimes
missing. cache/session.go:625 was changed correspondingly.

This CL also make CodeAction.Disabled into a pointer.

New requests or notifications:
DidCreateFiles, DidRenameFiles, DidDeleteFiles (notifications)
ShowDocument, WillCreateFiles,WillRenameFiles, WillDeleteFiles (request)

It's a lot of code; I've probably missed something.
