Category: 37. File System Group: None Status: Open Resolution: None Priority: 8 Private: No Submitted By: Brian Griffin (bgriffin) Assigned to: Vince Darley (vincentdarley) Summary: file writable broken Initial Comment: The [file writable] command is broken on Windows XP with samba server mounts. Since bug 1193497 & 1344540 changes were put in place, [file writable] appears to always return false for files on samba mounts. Evidence suggests that it is also restricted to Linux systems as other (sun) samba servers seem to not exhibit this behavior. Now, it is easy to suggest that the problem lies with the Linux version of samba, however, Tcl is the *only* application that has this problem. There is *no* evidence that *any* other windows applications have write access problems with these samba servers. I've been able to reproduce the problem using 8.4.14, and 8.5.0 rc3. The samba server I'm using is: $ rpm -q samba samba-3.0.10-1.4E.9 Running on: $ cat /etc/redhat-release Red Hat Enterprise Linux WS release 4 (Nahant Update 4) $ uname -a Linux modport 2.6.9-42.ELsmp #1 SMP Wed Jul 12 23:32:02 EDT 2006 x86_64 x86_64 x86_64 GNU/Linux My samba configuration is: [global] workgroup = mygroup server string = Samba Server printcap name = /etc/printcap load printers = yes cups options = raw log file = /var/log/samba/%m.log max log size = 50 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 dns proxy = no idmap uid = 16777216-33554431 idmap gid = 16777216-33554431 template shell = /bin/false password server = None username map = /etc/samba/smbusers winbind use default domain = no [homes] comment = Home Directories browseable = no writeable = yes [printers] comment = All Printers path = /var/spool/samba browseable = no printable = yes [scratch] path = /export/scratch writeable = yes guest ok = yes I believe this to be a high priority bug. I suggest backing out the patch from 1344540 and starting over. I believe the logic in the patch is flawed in some fundamental way. ---------------------------------------------------------------------- Comment By: Danny Zeng (dannyzeng) Date: 2009-02-11 13:47 Message: tcl 8.4 in Cygwin on the same machine does not have this issue. $ uname CYGWIN_NT-5.1 zeng@zeng-d630 ~ $ tclsh84 % cd z:/zeng % file writable test2.txt 1 % file writable test.txt 1 ---------------------------------------------------------------------- Comment By: Danny Zeng (dannyzeng) Date: 2009-02-11 13:45 Message: Reproduced this issue with ActivateTcl 8.5 - tcl can write to a file but "file writable" reported false. % info patchlevel 8.5.2 % pwd Z:/zeng % file writable test.txt 0 % cat test.txt >>test2.txt % dir Volume in drive Z is saber Volume Serial Number is 0E36-0531 Directory of Z:\zeng 2009-02-11 13:21 <DIR> . 2009-02-11 13:18 <DIR> .. 2009-02-11 13:35 39 test2.txt 2009-02-11 13:18 13 test.txt 2 File(s) 52 bytes 2 Dir(s) 38,612,762,624 bytes free ---------------------------------------------------------------------- Comment By: Danny Zeng (dannyzeng) Date: 2009-02-11 13:40 Message: Reproduced this issue with ActivateTcl 8.4.18.0 on a Windows XP machine.
