<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">note that KDiskFreeSpaceInfo can block for significant periods of time in certain cases; we've found this to be the case where the mount point being queried was a network drive that is no longer available (temporarily or permanently; disruption of network access triggers this case nicely). this can result in delays on the order of 15-30s on many systems.
as such, in plasma we've moved usage of KDiskFreeSpaceInfo into a separate thread on its own.
i'm not sure if this would end up a concern here (perhaps one can only copy to locations that are accessible?), but something to note.</pre>

<pre style="margin-left: 2em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">of course, this won't help much in the case where there is more than one copy job happening (in or out of KIO). though i suppose it will end up catching more cases than are caught now (e.g. none)</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">this is simple fix for 243160. It gets free space info for the dst partition, then after each successful file copy it decreases an internally kept m_freeSpace value.
this will help us avoid situations when user copies a 4gb long file onto his disk, then finds out it has not enough space available.
i hope that i correctly understood kio copy job mechanism and done error reporting right.
TODO (from what was asked in the bug):
*checking for single file size limit on vfat.
*if the total size is larger than free space, warn user beforehand immediately
(right now it does the copying until it finds that the next file cannot be copied completely)
both these require new dialogs with user visible strings and are subject to be added after 4.8.
also as a bonus i changed m_overwriteList to be qset instead of qlist to make lookup operations faster.
