A mapper is always uniquely tied to a file at a specific version, so
just build it when we get a new *ast.File. We build the mapper using the

Our original caching plan was to use only the file ParseGoHandles as
cache keys to define a given package. However, because of package test
variants, we cannot rely on files alone. A package may have the exact
same set of files, but be a test variant. Add the ID to the key to avoid
clobbering entries in the cache.
Also, remove the unused metadata ID cache.

Now when a file is deleted we force the file's packages to refresh
go/packages metadata, and kick off diagnostics.
I made a couple other changes to watched file handling:
- Kick off diagnostics in a goroutine to match how DidChange works.
This will allow us to work through big sets of file changes faster,
and will save duplicated work once type checking can be canceled.
- Don't assume a watched file is only part of one view.
Two interesting cases we don't handle yet:
- If the deleted file was the only file in the package, we don't
currently update diagnostics for dependent packages. This requires
rejiggering how diagnostics are invoked a bit.
- If the deleted file is still open in the editor and then later
closed, we don't trigger metadata/diagnostics refresh on DidClose.

On MacOS the default open file limit is 256 files per process. For big

By moving up the `parseLimit` so the reading of the file is only done
when it is allowed to start parsing the file, we stay well below the 256
files per process (as the `parseLimit` is currently set to 20).
Since `parseLimit` is actually only used to limit IO access, let's also
rename the const to `parseLimit`.

2. (*goFile).invalidateContent() acquires the "handleMu" mutex first and
then the "mcache" mutex.
Fix by changing the acquisition order in invalidateContent().
The second deadlock involved the file watcher. The two code paths
involved were:
1. (*goFile).GetPackages() holds the view mutex and eventually calls
(*WatchMap).Watch, which acquires the watcher mutex.
2. (*session).openOverlay acquires the watcher mutex as it triggers a

"(*goFile).invalidateContent" acquires the view mutex.
Fix by not holding the watcher mutex as we invoke the callbacks.

Previously when you added a new file to an existing package, the new
file would get stuck with the "no package for file" error until you
saved the file and then made changed a different file in the
package. There were two changes required to fix the errors:
First, we need to invalidate the package cache when a new file is
added to a package so that the package will actually re-parse and
re-type check. We now notice if file names changed when updating a
package's metadata and invalidate the package cache accordingly.
Second, when dealing with overlay (unsaved) files, we need to map
the *goFile to the package even if we fail to parse the
file (e.g. the new file fails to parse when it is empty). If we don't
map it to the package, the package won't get refreshed as the file is
changed.

This change brings back handling for circular imports, which was removed
because I originally thought that go/packages would handle that.
However, since we are type-checking from source, we still end up having
to deal with that.
Additionally, we propagate the errors of type-checking to the
diagnostics so that the user can actually see some of the problems.

This change adds a Package interface to the source package, which allows

This change adds an additional cache for type information, which here is
just a *packages.Package for each package. The metadata cache maintains
the import graph, which allows us to easily determine when a package X
(and therefore any other package that imports X) should be invalidated.
Additionally, rather than performing content changes as they happen, we
queue up content changes and apply them the next time that any type
information is requested.
