[ jEdit-devel ] I/O error: Permission denied (SFTP?)

[Ben W. <be...@we...>]

Howdy,

I sent this to jedit-users, but didn't get any responses; I figured I'd 
try sending it to -devel, see if anyone on here has any ideas. Sorry if 
you get this twice.

Hi All,

My apologies if this has been covered before - I couldn't find anything 
on google or in the list archives. I've just subscribed to this list.

I'm using jEdit 4.2pre15, and I'm editing files on a remote linux server 
via SFTP (using the fantastic FTP Plugin, v0.7.2). The ownership & 
permissions on the files are important to maintain - I'm not the owner, 
but I am a member of the owner's group and the group permissions are 
such that I can modify the files. This works fine if editing in an ssh 
terminal.

If I use the Two-stage save option, my files save fine, but the file 
ownership & group reverts to my username & primary group (different to 
the group that originally owned the files) - not what I want.

If I don't use the two-stage save, the contents of the file is updated 
successfully, but I get an error dialog with the following message:

     sftp://ben@my.host.com.au:22/my/file.php:
     Cannot save: java.io.IOException: Permission denied

I get the following relevant lines in the Activity Log:

I believe it's the chmod line (ftp.SFtpConnection.chmod) that is 
producing that error - indeed, I can't chmod the files in a ssh terminal 
either (which is expected behaviour).

I know jEdit has some kind of permissions-maintaining code in it's save 
routine. I guess the question is, is this a problem with the FTP plugin, 
or with jEdit? Is there any way I can stop jEdit and/or the FTP plugin 
from trying to execute the chmod?

Possibly relevant info: Client - Windows XP (not SP2), Sun J2RE 
1.4.2_04, jEdit 4.2pre15, FTP Plugin 0.7.2; Server - Redhat 7.2, ext3 
filesystem.

(This might be related to bug 978894 on sourceforge? 
<http://sourceforge.net/tracker/index.php?func=detail&aid=978894&group_id=588&atid=100588>)

Thanks in advance,

  - Ben
