Yet another vgo test project
Consider the following flow:
A(v0.0.1) uses B(v0.0.1):
module github.com/mwf/vgo-modules/a
require github.com/mwf/vgo-modules/b v0.0.1
Then A(v0.1.0) drops the dependency.
Here we got a project main which uses A(v0.0.1) and we want to upgrade A to v0.1.0
cd `mktemp -d`
git clone https://github.com/mwf/vgo-modules .
echo "\n$(cat go.mod)"
echo "\n$(cat go.sum)"
go get github.com/mwf/vgo-modules/[email protected]
echo "\n$(cat go.mod)"
Output:
module github.com/mwf/vgo-modules
require github.com/mwf/vgo-modules/a v0.0.1

module github.com/mwf/vgo-modules
require (
github.com/mwf/vgo-modules/a v0.1.0
github.com/mwf/vgo-modules/b v0.0.1 // indirect
)
We get an unexpected indirect dependency github.com/mwf/vgo-modules/b v0.0.1 // indirect in go.mod, it seems to be taken from go.sum as a side-effect.
Consider the following flow:
C(v0.1.0) uses A(v0.1.0):
module github.com/mwf/vgo-modules/c
require github.com/mwf/vgo-modules/a v0.1.0
Then A(v0.2.0) is released and C(v0.2.0) depending on new A(v0.2.0).
We got a project main which uses C(v0.1.0) and we want to upgrade C to v0.2.0
cd `mktemp -d`
git clone https://github.com/mwf/vgo-modules .
cd c_user
echo "\n$(cat go.mod)"
echo "\n$(cat go.sum)"
go get github.com/mwf/vgo-modules/[email protected]
echo "\n$(cat go.mod)"
Output:
module github.com/mwf/vgo-modules/c_user
require github.com/mwf/vgo-modules/c v0.1.0
github.com/mwf/vgo-modules/a v0.1.0 h1:QD+ijrXwAYk4CMTOqEAzcogJoF4zLfit2alZVmT80EM=

module github.com/mwf/vgo-modules/c_user
require github.com/mwf/vgo-modules/c v0.2.0
All seems OK, than we run tests and understand that C(v0.2.0) is broken - go test .
--- FAIL: TestC (0.00s)

We decide to downgrade C back to v0.1.0 used before:
go get github.com/mwf/vgo-modules/[email protected]
echo "\n$(cat go.mod)"
go test .
After the downgrade we get unexpected github.com/mwf/vgo-modules/a v0.2.0 // indirect and tests still fail.
module github.com/mwf/vgo-modules/c_user
require (
github.com/mwf/vgo-modules/a v0.2.0 // indirect
github.com/mwf/vgo-modules/c v0.1.0
