In several places throughout the x/tools codebase, the internal/lsp/diff
package is used to provide clearer test output when comparing large,
multi-line strings. In some places, this is implemented via the
tests.Diff helper function, but in others it is not (presumably due to
import cycles).
Factor out this pattern into a diff.Pretty function, and add commentary.
Also remove the *testing.T argument, as diffs should never fail; opt to
panic instead. Also add a test.
Using this function, simplify the logic to comparing our 1.18 markdown
output with 1.19 golden content, by normalizing differences between the
two.
This is necessary as markdown content will change as a result of moving
internal/lsp to gopls/internal/lsp.

This does rather explain why type-error analyzers are executed

This change consolidates the logic of the memoized function
for analysis (previously split across execAll and runAnalysis)
to make the error control flow clearer. The new function,
actionImpl, follows the same conventions as in other memoized
functions.
Errors from await (e.g. cancellation) are now separate from
errors from analysis itself. Only the latter are now ignored
in the diagnostics loop over the roots.
Also, where previously the recursion would ignore failed
dependencies (proceeding to call runAnalysis even after
seeing an &actionData{err!=nil}), now the recursion aborts
if one of the prerequisites fails, as it should.
The only edges currently enabled are "horizontal" (inputs,
not facts). This would explain the crash in golang/go#54798,
in which the result of the nspector pass was not available
to the structtag pass.
Also:
- merge the loops over deps in execAll and runAnalysis.
- remove unnecessary checks for context cancellation in
loops of pure computation.
- don't suppress errors from awaitPromise.
- add commentary.
- turn two "can't happen" errors into panics.
- remove unnecessary logging of analysis failures.

The diagnostics emitted by the Go toolchain vary from one
release to the next, and the gopls tests run against multiple
versions. Therefore our tests need a way to express multiple
possibilities in their expectations. This change interprets
the patterns in @diag test annotations as regular expressions,
allowing some flexibility in recognizing both old and new
messages. It's not a panacea but it is one step to reducing
the considerable friction of making changes to the compiler
or go/types in the main tree.
Details:
- Factor the three implementations of the Tests.Diagnostics
abstract method so that they all use DiffDiagnostics
to report differences, substantially rewriting one of them.
- Move the "no_diagnostics" hack, of which there were three
copies, not all consistent, into DiffDiagnostics.
- Eliminate the named type for each tests.Data field;
a type alias is all that's needed.
- Add Diagnostics.String method.
- Add various TODOs for further improvements.
- Add various apparently missing Fatal statements within

- Add TODO to fix another panic in an analyzer that is covered

To support the experimentalUseInvalidMetadata mode, we keep around
invalid metadata. This can help gopls features work when, for example,
the go.mod file is broken. It is debatable whether this feature is worth
supporting (see golang/go#54180), but in the meantime there is a very
negative side-effect when module paths are changed in the go.mod file:
we keep around a bunch of workspace packages with a stale module path.
As a result we can be left with a lots of extra type-checked packages
in memory, and many inaccurate diagnostics.
Fix this by skipping packages with invalid metadata when computing
workspace packages. While we may want to use invalid metadata when
finding the best package for a file, it does not make sense to re-
type-check and diagnose all those stale packages.

Semantic tokens, as defined by the LSP, have no way of marking parts of
strings or numbers, for instance, to emphasize escape character. But
if gopls returns no semantic tokens for strings, then the editor
will use its coloring for strings, which may be more useful (and
similarly for components of numbers).
This change introduces boolean flags noSemanticString and
noSemanticNumber that can be set to true to suppress the semantic
token and let the editor's formatting shine through.

By making gopls.run_vulncheck_exp (RunVulncheckExp implements)
call `gopls vulncheck`, we achieve
- gopls.run_vulncheck_exp can run asynchronously and be cancellable
- log information can be forwarded as progress messages
- isolate any failures during vulncheck execution
In this CL, we also changed not to include test files in the analysis
(match the default of govulncheck). We will add an option in the future.
TODO:
- prevent concurrent gopls.run_vulncheck_exp
- convert the gopls vulncheck output to diagnostics and publish it
- remove timestamps from the `gopls vulncheck` log messages
for simplify progress messages
- add test to check vulnerability in third-party dependencies

Based on dle8's CL 414454, wire in directoryFilters into the goimports
ModuleResolver scan. A few changes/fixes/additions from that CL:
- Fix a bug in filter validation that was causing -**/a not to validate.
- Fix a bug in regex building where -a was not treated as an excluded
prefix (it was matching 'a' anywhere).
- Use absolute paths in the SkipPathInScan, so that we can evaluate
directory filters relative to the workspace folder.
- Add several regression tests.
- Consolidate directoryFilters regression tests under a new
directoryfilters_test.go file.
- Add several TODOs.

Significantly refactor the gopls benchmarks to turn them into proper
benchmarks, eliminate the need for passing flags, and allow running them
on external gopls processes so that they may be used to test older gopls
versions.
Doing this required decoupling the benchmarks themselves from the
regtest.Runner. Instead, they just create their own regtest.Env to use
for scripting operations. In order to facilitate this, I tried to
redefine Env as a convenience wrapper around other primitives.
By using a separate environment setup for benchmarks, I was able to
eliminate a lot of regtest.Options that existed only to prevent the
regtest runner from adding instrumentation that would affect
benchmarking. This also helped clean up Runner.Run somewhat, though it
is still too complicated.
Also eliminate the unused AnyDiagnosticAtCurrentVersion, and make a few
other TODOs about future cleanup.

Fixgolang/go#50267 by ensuring that diagnostics are re-sent following
didOpen or didClose events. Additionally, introduce a new hidden
'chattyDiagnostics' option that causes diagnostics to be resent on
*every* file change event. This latter option is for LSP clients that
get confused when diagnostics are not re-sent for later file versions.
For now, be conservative and only force diagnostic publication on
didOpen and didClose.
Update tests whose 'NoDiagnostics' assertions were broken by the new
behavior.

Requesting gc_details for an empty file never worked, but in the past it
would inadvertently get handled by our forgiving position helpers. With
https://go.dev/cl/409935, it became a crasher.
Fix the crash by adding handling when the package name position is
invalid.
Also move gc_details related codelens to their own file.

Following up on CL 417587, make several improvements to the regtest
runner related to shared execution modes:
- guard lazily-allocated resources with sync.Once rather than a common
mutex.
- for simplicity, always set Runner.goplsPath
- start the separate process server synchronously, to ensure that it is
running before test execution
- cancel the separate process server when the test runner exits
- remove the testing.T argument from server constructors
- close the regtest runner in a deferred function
Tested manually via -enable_gopls_subprocess_tests.
