Bug 1143965

What were the ownership/permissions of the original file?

root:root

the machine is mounted for several reasons like below
500 = uid = harry
501 = gid = verwaltung

the main question is why do kate try to change the owner/group at all?
in case of open a exsiting file i don't expect das perms/owner/group are changed in any way by save it only because if have the permissions to do so - this can introduce all sort of troubles if you work on a server with restricted permissions of specific files for security - the case above only don't harm because of chmod 0644, with chmod 0640 postfix would no longer be able to read the file

sshfs#root@hostname:/ /mnt/hostname fuse noauto,user,rw,noexec,nosuid,nodev,uid=harry,gid=verwaltung

BTW: as far as i remember Konqueror had exactly the same problem in earlier KDE4 days by copy a file over a existing one with kio-sftp slave leading to break complete websites by replace a config-include

If the permissions were 644 and owned by root, then the only way to save the file would be to replace it (assuming your user had write permission to the parent directory).

Hum? from the view of the server *i am root* and i *have* write permissions
just write into that file and don't touch anything

opening the *identical file* in the identical environment with Eclipse and all is fine - only KDE components tend to make troubles on network FS

just write *into* that file instead play around with try to replace it atomic
this behavior has a lot of bad impact round the complete stack (Knoqeuror and so on)

* the parent directory is read-only
* you have read permissions to it
* you have the permissions to edit a single file
* it fails by try to generate a temporary file and renmae it finally

the scenario is *completly legit* to prevent somebody just rename a read-only file, create a new one and give it the filename of the previously renamed read-only - not only once i had users exceed there intented permissions that way

example: the user has write permissions to a config file but not to the script files around

forget the atomic replacement - it defeats to chose wise security settings without making users work impossible

again: i mount the sshfs as root, so no you can just save it as usual, other software like eclipse can without change woner/group to th numeric ones of the client

it is really annyoing :-(

and it is the Apple Inc. way

why not just try to save as usual instead magically guess what is possible and only if that fails fall back to replaced it? 

that would also solve *a ton* of problems where you have write permissions to a specific file *but* not the parent folder 

the reason for such a setup is a design mistake in unix: forbid rename files you don't have write permissions to and palce a new ones is not possible in any other way except using ACL's

GOD DAMNED - each time you edit a file with kate things breaking because changed owner/groups - the devlopers should eat their own dogfood and work on machines used my multiple users each of them in more that one group

and yeah that happens even for files on my local machine when they have chmod 644 and group 'apahe' so that the webserver can read them when after save with kate the group is no longer apache

how many years does it take to simply act like eclipse here instead ruin permissions on such a basic task like open a file, chnage some chars and press save?
