Attachments:	Patch to remove backup file before attempting to copy to it

Description Robby Stephenson 2008-12-24 08:20:58 UTC

Version:            (using KDE 4.1.3)
OS:                Linux
Installed from:    SuSE RPMs

KSaveFile::simpleBackupFile eventually calls QFile::copy with the backup file name. However, if the file exists, QFile::copy just fails.

I would expect the behavior to be such that existing backup files would be overwritten by repeated calls to simpleBackupFile(), in which case, old backups should be removed before calling QFile::copy(). The numberedBackupFile() function does this.

I'll attach a simple patch.

SVN commit 901154 by winterz:

In simpleBackupFile(), remove the backup file before copying the source file.
This makes the copy work, just in case a backup file already exists.

The remove will fail if a backup file doesn't exist (on the first call),
but that's ok.

Patch from Robby Stephenson.
