Tcl Source Code

If tcl is started on a networked drive and you choose to have it available offline
using 'Windows 7/10 Offline Files' feature and then run it offline (after being 
fully synchronized) the following commands return always '0':

file readable
file writable

Other file commands, e.g. file exists, or opening the files work.
If online again the commands return '1' as expected.

Dear Harald,

thank you for the report. On the practical side, *file readable* and *file writable* are at the moment not usable under windows due to bugs. And you have found another one.

Here are links to the issues: Ticket [1613456fffffffff] Wiki page: http://wiki.tcl.tk/10081

The only reliable way is to use *file exists* and if you really want to know if it is readable, use *open*.

Any fix or clue welcome.

Thank you, Harald
