77f530d86f internal/lsp: handle deletion of file content
We had previously been treating file changes with no content in the same
way as the deletion of content. Now, we distinguish between the two.

Fixes golang/go#38424.

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.

58eba7e750 internal/lsp: refactor go.mod diagnostics to simplify the API
Currently, diagnostics for modules that are missing from the go.mod
appear in the Go files in which those modules are imported. As a result,
the diagnostics were previously calculated as part of the Go file
diagnostic calculations. This is convoluted and required passing around
an extra map.

This CL puts that logic in the ModTidyHandle where it belongs.
The diagnostics for the Go files are combined from the multiple sources.

Also, added a skipped test for golang/go#39784, since this CL was
originally intended to be a fix for that issue...

f2c07d7d8e internal/lsp/lsprpc: improvements to daemon logging
The gopls daemon had different default logging behavior than the sidecar
gopls: by default, the daemon was started with -logfile=auto.
Additionally, because most logs are reflected back to the forwarder, the
actual daemon logs have very little (if any) information.

This means that if you simply start gopls with -remote=auto, you'll get
a single logfile named /tmp/gopls-<pid>.log, which is mostly empty. This
is not a delightful experience.

Fix this via several improvements:
 + Log lifecycle events in the Daemon, to give the log a purpose.
 + Give the daemon a new default log location:
   /tmp/gopls-daemon-<pid>.log.
 + Don't pass -logfile=auto to the daemon by default.

cf799caead internal/lsp/regtest: simpler way to invert options

a8f9df4c95 internal/lsp: clean up the code lens code
This change refactors lens funcs to use only a FileHandle - each
code lens should manually compute a ParseGoHandle if it's needed. The
issue was that, if the code lens needed to also get a package, the
already parsed *ast.File was not necessarily the file used in
type-checking that package. I noticed that the code lens wasn't always
coming up.

f1c4188a97 internal/lsp, go/packages: reproduce and fix golang/go#39646
This test exposes a lot of fundamental issues with `go list` overlays.
Now that we have the regression test framework, we can copy it over and
make any flakes completely reproducible by waiting for each change to
complete.

The issue here ended up being that initial workspace load returns
workspace packages with no associated files due to golang/go#39986.
Working around this allows invalidation to proceed as usual.

In the process of debugging this, I also noticed that packages can get
loaded as command-line-arguments even when we can get the correct
package path for them. It's pretty complicated to fix this, so
restructured the code a tiny bit and left a TODO. I'd like to come back
to this at some point, but it's not pressing since I was able to fix
this bug.

065b96d36c internal/lsp/cache: fix race in RunProcessEnvFunc
Changing build flags (-modfile) while work is happening in the
background causes races. Explicitly detect relevant configuration
changes and only modify the ProcessEnv then, when the resolver is
inactive after the call to ClearForNewMod.

This still leaves a very small window for a race: if refreshProcessEnv
has already captured env but not yet started priming the cache, it may
race with the modification. But I don't expect it to be a problem in
practice.

Fixes golang/go#39865.

416e8f4faf internal/imports: require valid options, move LocalPrefix up
CL 239754 eagerly initialized the environment. This turns out to be a
problem for gopls, which calls ApplyFixes with no ProcessEnv.
Reinitializing it every time seriously harmed the performance of
unimported completions. Move back to lazy initialization.

Working with invalid options has caused a lot of confusion; this is only
the most recent. We have to maintain backwards compatibility in the
externally visible API, but everywhere else we can require fully
populated options. That includes the source byte slice and the options.

LocalPrefix is really more of an Option than an attribute of the
ProcessEnv, and it is needed in ApplyFixes where we really don't want to
have to pass a ProcessEnv. Move it up to Options.

CL 226639 changed the positions of the go.mod diagnostics (in a
negligible way), but the tests are quite brittle and can't handle the
different position. Rewrite this test as a regression test to handle it.

The special // indirect marker can be removed from the go/expect package
as a result, since it was only used in this one place.

0cc1aa72b3 gopls/internal/hooks, internal/lsp/source: only match full words in link regexes
The current URL regexes (including xurls) match links in any part of a
string. However, this leads to odd underlining within words which just
so happen to have valid domain names as substrings. For example, a
comment which contains "reflect.DeepEqual" will match the URL regex as
"reflect.de" is a domain name.

Ensure that the URLs only match full regex words by adding \b around the
expressions. For xurls, this is done by pulling the expression out of
Relaxed() and recreating the Regexp.

While I'm here, make the non-gopls module expression prefer the longest
match, as xurls does.

f01a4bec33 internal/lsp: support opening single files
This change permits starting gopls without a root URI or any workspace
folders. If no view is found for an opened file, we try to create a new
view based on the module root of that file. In GOPATH mode, we just
use the directory containing the file.

I wrote a regtest for this by adding a new configuration that gets
propagated to the sandbox. I'm not sure if this is the best way to do
that, so I'll let Rob advise.

1837592efa internal/lsp/source: speed up completion candidate formatting
Completion could be slow due to calls to astutil.PathEnclosingInterval
for every candidate during formatting. There were two reasons we
called PEI:

1. To properly render type alias names, we must refer to the AST
   because the alias name is not available in the typed world.
   Previously we would call PEI to find the *type.Var's
   corresponding *ast.Field, but now we have a PosToField cache that
   lets us jump straight from the types.Object's token.Pos to the
   corresponding *ast.Field.

2. To display an object's documentation we must refer to the AST. We
   need the object's declaring node and any containing ast.Decl. We
   now maintain a special PosToDecl cache so we can avoid the PEI call
   in this case as well.

We can't use a single cache for both because the *ast.Field's position
is present in both caches (but points to different nodes). The caches
are memoized to defer generation until they are needed and to save
work creating them if the *ast.Files haven't changed.

These changes speed up completing the fields of
github.com/aws/aws-sdk-go/service/ec2 from 18.5s to 45ms on my laptop.

Fixes golang/go#37450.
