We replace the current Open with:
OpenFile(name, flag, perm) // same as old Open
Open(name) // same as old Open(name, O_RDONLY, 0)
Create(name) // same as old Open(name, O_RDWR|O_TRUNC|O_CREAT, 0666)
This CL includes a gofix module and full code updates: all.bash passes.
(There may be a few comments I missed.)
The interesting packages are:
gofix
os
Everything else is automatically generated except for hand tweaks to:
src/pkg/io/ioutil/ioutil.go
src/pkg/io/ioutil/tempfile.go
src/pkg/crypto/tls/generate_cert.go
src/cmd/goyacc/goyacc.go
src/cmd/goyacc/units.y
