The old code didn't stop after finding the fallthrough target, always
walking the entire list to the top. This would effectively break
fallthroughs, constructing an invalid graph, as the fallthrough target
would never be found.
The fix brings the loop condition in line with all the other
stack-walking loop conditions in the surrounding code, which abort
once the target block has been found.
Alternatively, the entire loop could been omitted, as 'fallthrough'
has to be the last statement in a case body and thus always refers to
the immediate element on the stack. However, since the builder already
handles malformed ASTs as gracefully as possible, it seemed better to
keep the loop and to construct a slightly less wrong graph in the
presence of malformed ASTs.
Before the fix, the following code
func fn(x int) {
for {
switch x {
case 1:
println("case 1")
fallthrough
case 2:
println("case 2")
}
}
}
would result in the following graph. Note the presence of an
undefined.branch block.
.0: # entry
succs: 1
.1: # for.body
x
1
succs: 4 6
.2: # for.done
.3: # switch.done
succs: 1
.4: # switch.body
println("case 1")
succs: 7
.5: # switch.body
println("case 2")
succs: 3
.6: # switch.next
2
succs: 5 9
.7: # undefined.branch
.8: # unreachable.branch
succs: 3
.9: # switch.next
succs: 3
After the fix, this graph is computed instead:
.0: # entry
succs: 1
.1: # for.body
x
1
succs: 4 6
.2: # for.done
.3: # switch.done
succs: 1

The imports ProcessEnv contains cached module and filesystem state. This change
allows gopls to use the same ProcessEnv and resolver across multiple calls to the

A ProcessEnv belongs to a view, because the cached module state depends
on the module that is open in the workspace.
Since we do not yet track whether the 'go.mod' file has changed, we
conservatively reset the cached state in the module resolver before
every call to imports.Process.

Refactors allpaths to print an adjacency list from "from" to "to", instead of
just the nodes. This allows other tools like modgraphviz to print the subgraph.
For example, the following command:
cd $GOPATH/src/cloud.google.com/go && \
go mod graph | \
digraph allpaths cloud.google.com/go golang.org/x/text@v0.3.2 | \
modgraphviz | \
dot -Tpng -o graph.png
Generates the following graph.png: https://user-images.githubusercontent.com/3584893/60481727-df0a8680-9c4b-11e9-8df9-c581d599edd1.png
Also splits out the allpaths tests into their own test, and adds many test
cases.
This is a breaking change. The previous behavior returned vertices; now it
returns edges. If you relied on the previous behavior, use:
my-application | digraph allpaths <from> <to> | digraph nodes

If typeCheck() returned an error, we could get into a state where a
package had an entry in the pcache, but the package's files had an
empty "pkgs" map. When we got a DidChange event for one of the files,
no packages would get invalidated since the file's "pkgs" was
empty. This resulted in the cached typeCheck() error persisting
indefinitely. Fix by never caching pcache entries on error.
An easy way to reproduce the problem was to delete the package name
from a file. For example, edit "package foo" to be just
"package". This caused the package to get stuck with an "AST for %s
has an invalid position" error.
