Using root.MkdirAll to create a path, with the given path ending in a / results in the following error:
mkdirat some/path/: no such file or directory
main.go to reproduce:
package main
import (
"log"
"os"
)
func main() {
r, err := os.OpenRoot(".")
if err != nil {
log.Fatalf("OpenRoot: %s", err.Error())
}
err = r.MkdirAll("some/path/", 0755)
if err != nil {
log.Fatalf("MkdirAll: %s", err.Error())
}
}Running the above program with 1.26.5 or 1.25.12 results in the error:
GOTOOLCHAIN=go1.26.5 go run main.go
GOTOOLCHAIN=go1.25.12 go run main.go
Using prior patch versions works as expected.
Changing some/path/ to some/path is a workaround.
