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.

Suzy Mueller 16b25d25b9 internal/lsp: print comments that would be lost during extract func
Due to the limitations of comments in ast, it is difficult to move
comments. The extract function feature currently does not handle
comments at all. This change instead prints the comments that would
have been lost above the call to the function, so that the user can
easily recover them. Otherwise, it was possible for users to lose
comments and not notice.

Shoshin Nikita d0768c9130 internal/lsp/source/completion: suggest only valid package names
Before this change directory names were used "as is" for package completion.
It could lead to invalid suggestions (for example, 'package 1abc' or package 'ab-cd').

This change adds a check whether a directory name can be used in a package path.
If the directory name is invalid, only 'package main' will be suggested.
Otherwise, the directory name will be normalized and will be used as a package name.

Note: normalized directory names contain only lower case letters and digits.

Rob Findley 7c93484b9a internal/lsp: add a command to start the debug server
The utility of the debug server is limited by the requirement to start
gopls with the `-debug` flag and then look in the logs to see which port
the debug server is bound to.

This CL adds a new custom command `gopls.startDebugging` to start the
debug server on demand if it isn't already running, and return its debug
address. It also does some gymnastics to make this turn on debugging for
any intermediate gopls forwarders, when using daemon mode.

In cases like:

We weren't detecting that the selector preceding <> was a statement.
The above is parsed as "foo.<>bar = 123", so it looks like <> is
contained in an AssignStmt. This matters because we give different
postfix completions depending on whether it is valid to replace the
surrounding selector with a statement or not.

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.

pjw dbc8747628 internal/lsp/semantic: avoid doing semantic tokens for large files
LSP (and gopls) support both full-file semantic token requests and
requests for just a range, typically roughly what's visible to the user.
It can be slow to produce the full set for a very large file, so
this code now responds with an error if the file is bigger than
100,000 bytes. After getting this error, vscode, at least,
will stop asking for full requests and use range requests.

Alternatively, server capabilities could say gopls never responds to
full-file requests, but doing that doesn't stop vscode from asking for
them. Another possibility would be to fix a time limit (like 8ms) for
how long to spend generating full-file semantic tokens. That's tricky
to get right, but one could instead generate an error when there
are more than 4,000 semantic tokens (on my laptop, that's about 8ms.)

Large files are unusual; a simple size limit seems adequate for now.

candidates such as "bits.LeadingZeros()", "time.Now().Day()", or
"zlib.BestCompression", depending on your luck. These candidates stem
from unimported packages candidates such as "bits" which we continue
searching into for deep candidates.

There are two main reasons these deep completions are not useful:
1. They are not dependable. Not all unimported packages are even
   searched (it stops as soon as it finds a set number).
2. Fuzzy matching does not work (e.g. typing "bilz" will not filter to
   "bits.LeadingZeros" as it does in other cases).

2) could be remedied, but there are so many unimported
package members that I'm not sure it is possible to reduce false
positive deep completions to a satisfactory level.

I also made a couple relevant minor tweaks:
- Fallback sort the unimported packages by path to keep a consistent
  order.
- Don't offer unimported packages at all if there is no prefix.

Heschi Kreinick 1dce19db54 internal/lsp/cache: don't trim types.Info with staticcheck enabled
As predicted in CL 308730, there are some analyzers that need this: all
of staticcheck. (I probably should've seen that coming.) For now, don't
do the trimming when staticcheck is on. Since staticcheck ~doubles
memory footprint, those users probably don't care much.

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.

Rob Findley 35a9159336 go/internal/gcimporter: ensure that imported floats are of float kind
As of CL 290630, go/types enforces some bitsize limits on integer const
values. We need to be careful to preserve the constant Kind when
importing from gc export data.

Ideally we could follow CL 288632, but the go/constant APIs used in that
CL are not available to x/tools, which (at least for the moment) must
still build at go1.12. Instead, simply call constant.ToFloat to force
the Kind.

Add a test for the imported Kind. This test should probably also be
upstreamed to std/go/internal/gcimporter, now that go/types relies on
this behavior.
