What did you do?

  1. create a repo with valid go files + non-go files containing | chars in filenames: https://github.com/moul/test-go-mod-malformed-path
  2. create another repo that depends on the first one: https://github.com/moul/test2-go-mod-malformed-path
  3. without go mod, you can go build
  4. with go mod:
    $ go mod vendor
    go: finding github.com/moul/test-go-mod-malformed-path latest
    go: extracting github.com/moul/test-go-mod-malformed-path v0.0.0-20180912153824-5c1104fa0b94
    -> unzip /Users/moul/go/pkg/mod/cache/download/github.com/moul/test-go-mod-malformed-path/@v/v0.0.0-20180912153824-5c1104fa0b94.zip: malformed file path "non-go-file-with-pipe|char.txt": invalid char '|'
    go: no dependencies to vendor

What did you expect to see?

go mod vendor should success

What did you see instead?

go mod vendor failing with the above message

The module zip format is intended to be portable across filesystems. The pipe character is reserved on Windows, so it cannot appear within a module either. (We may eventually relax that requirement — for example, by escaping disallowed characters — but for now it is what it is.)

It is usually possible to avoid the problem by placing another (possibly-empty) go.mod file within the directory containing the disallowed file, thus excluding it from the parent module (and from that module's zip file).

As far as I can tell, this is working as intended.
