[Pkg-xfce-devel] Bug#583325: thunar: copying progress is misleading because files are not synced to disk

[John Lindgren]

Package: thunar
Version: 1.0.1-4
Severity: wishlist

Hi,

When I'm copying a bunch of files from a fast file system (say, my hard
disk) to a slower one (say, an MP3 player), the progress bar that is
shown represents only the progress in reading the files, not writing
them.  If the files are already loaded into cache memory (say, if I just
ripped them from a CD), the problem is even worse: the files are "read"
so quickly that no progress dialog is displayed.  Thunar then locks up
unmounting the player, while all the files are written to disk, which
can be on the order of thirty seconds.

It seems that the files are merely being written to a kernel write
buffer; if so, the trivial fix would be to call fsync() before closing
each file that is written.  I can't think of any reason not to do this.

Peace,
John Lindgren
