Robert Findley e7c9de23ff internal/lsp/cache: remove unsynchronized write to snapshot.files
snapshot.GetVersionedFile already memoizes the file handle in
snapshot.files. There is no reason to do another write, and this write
is unsynchronized.

Bryan C. Mills 342596760e gopls/internal/regtest/workspace: temporarily skip TestWatchReplaceTargets
This test has a high failure rate on the builders, and the failures
appear to be mostly platform-independent. This change skips the test
until the failures can be diagnosed and fixed.

Marwan Sulaiman 9f83dd3691 internal/lsp/source: use the real type parameter in snippet completions
This change makes source.FormatVarType return the instantiated type
parameter instead of the actual AST expression because that will just
refer to the abstract type parameter and not the insantiated one.
I am not sure if this covers all edge cases or if there's a better
solution but I'm happy to adjust to whatever is appropriate.

Robert Findley 80963bc8f5 go/internal/gcimporter: support unique naming for blank type parameters
As described in golang/go#50481, in the existing export data schema
blank type parameters do not have unique names, and therefore types with
multiple blank (receiver) type parameters cannot be correctly imported.

This CL implements the fix proposed in that issue, using the schema
<prefix>.$<index> as the exported name of a blank type parameter, where
<prefix> is the qualifying prefix and <index> is the index of the type
parameter in its type parameter list. The importer is backwards
compatible with the old schema: it will continue to import <prefix>._ as
long as there are not multiple blank type parameters.

I considered not making the exporter change simultaneously with the
importer change, so that we interleave the corresponding changes in the
standard library. However, that made it harder to test the importer, and
updating both seems unlikely to cause problems.

A_D eb07148636 gopls: add string join/split postfix completions
This adds two new snippets, centred around string manipulation.

The first snippet applies to variables of type string, and is called
split. When used, it replaces `someStringVar.split!` with
`strings.Split(someStringVar, "|")`, where `|` indicates the location of
the cursor.

The second snippet is essentially the same as the first, but in
"reverse". Meaning that rather than going from a string to a slice of
strings, it goes from a slice of strings to a single string:
`someStringSlice.join!` -> `strings.Join(someStringSlice, "|")`.

Robert Findley f234b3d4ab internal/lsp/source: keep collecting symbols on metadata errors
Workspace symbols requests fail when a file in the workspace is missing
metadata, such as if a build-tagged file is open in an overlay. We keep
going if metadata is missing, but not on metadata errors (such as
packages.Load errors).

Change this to log and keep going on errors.

Robert Findley 94bfe6897a internal/lsp: don't get the snapshot asynchronously on config changes
Server.didChangeConfiguration spins off a goroutine to diagnose the
reconfigured view, but this goroutine was calling View.Snapshot(), which
is not safe to call outside of jsonrpc2 serialization, because
the view may have been deleted.

Instead acquire the snapshot synchronously and just release it after
diagnosing. This should be sufficient, because any subsequent snapshot
change should have triggered a diagnostic anyway.

Bryan C. Mills 351aaa669b internal/lsp/tests: re-enable MultiModule tests on plan9
According to https://go.dev/issue/50478#issuecomment-1006947143, Plan
9 does not support renaming across directories. For the MultiModule
test cases we want to rename go.mod to testdata/go.mod, so we need to
fall back to copying if os.Rename fails.

Bryan C. Mills a1300ed2ba internal/lsp/tests: remove unnecessary uses of t.Helper
The purpose of t.Helper is to attribute test failures to the caller's
file and line number. However, in lsp.TestLSP (and in tests.RunTests)
the reason for a given failure tends to have little to no relationship
to the caller code, so it is more useful to attribute failures to the
specific part of the setup that fails.

Remove home-made popcount/nlz/ntz routines, now that the standard
library provides them. The Popcount benchmark (now deleted) showed that
the std implementation was much faster (0.45ns vs 1.5ns) on an Intel Core i9
(MacBook Pro), likely due to the compiler's intrinsic reduction of OnesCount
to an inline POPCNT instruction, avoiding the function call overhead.
