cmd/go: go work sync corrupts go.sum #50038
Description
What version of Go are you using (go version)?
% gotip version go version devel go1.18-cf1ec17360 Tue Dec 7 21:54:30 2021 +0000 darwin/amd64
What did you do?
Attempting to remove replace from golang.org/x/tools/gopls/go.mod,
set up the workspace like https://go-review.googlesource.com/c/tools/+/369959
% cat go.work
go 1.18
use (
./.
./gopls
)
Then, ran gotip work sync.
What did you expect to see?
gopls/go.mod and gopls/go.sum are updated to reflect dependency changes (maybe?)
OTOH, I don't know what's the intended behavior.
The development was done using an uncommitted golang.org/x/tools module version.
If the code in golang.org/x/tools/gopls module depends on uncommitted changes in
golang.org/x/tools module, it's not possible to create a working go.mod /go.sum until
the change for golang.org/x/tools module is first committed & released.
It's likely I misunderstood the purpose of gotip work sync.
What did you see instead?
Changes like this : https://go-review.googlesource.com/c/tools/+/370194/1
See the go.sum file missing all entries.
