weekly.2011-04-13
This weekly snapshot includes major changes to the reflect package and the
os.Open function. Code that uses reflect or os.Open will require updating,
which can be done mechanically using the gofix tool.
The reflect package's Type and Value types have changed. Type is now an
interface that implements all the possible type methods. Instead of a type
switch on a reflect.Type t, switch on t.Kind(). Value is now a struct value
that implements all the possible value methods. Instead of a type switch on a
reflect.Value v, switch on v.Kind(). See the change for the full details:
http://code.google.com/p/go/source/detail?r=843855f3c026
The os package's Open function has been replaced by three functions:
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)
To update your code to use the new APIs, run "gofix path/to/code". Gofix can’t
handle all situations perfectly, so read and test the changes it makes before
committing them.
