Hi Edward,
first thank you for your work.
I'm using reiser4 for all my partitions on my working machine with
kernel 2.6.37 with no problems
except one annoying one that is going on from months.
When I copy a file (whatever) from one directory to another with
konqueror, dolphin or krusader with
kde 4.6.1 the file get copied, it's size is correct but it is empty.
This happen only in the partitions formatted with reiser4 and not on
the xfs, reiser3 ones.
Thank you,
warm regards,
Paolo

I suspect that it's similar to what I experienced with gnome upgrade
back in time. My problem was due to issues in splice code path which
GNOME switch to for file copying along the way. I already reported
this to GNOME [1] as well as this ML [2,3]. The issue appearing in
only uncompressed partitions is interesting, Edward already asked me
It seems this is because of the following not implemented "todo":
int write_begin_unix_file(struct file *file, struct page *page,
loff_t pos, unsigned len, void **fsdata)
{
...
if (info->container == UF_CONTAINER_TAILS) {
warning("edward-1563", "Option not implemented");
drop_exclusive_access(info);
return -EINVAL;
}
Tail conversion should go in this branch.
I'll try to implement it for .38, and we'll see,
if this was really the issue.
Thanks,
Edward.
if mine was, which isn't. My current workaround is to use a patched
version of glib (part of gnome libs) that avoids using splice for
reiser4 targets. If you have a KDE bugzilla account, can you also
provide them links for discussions in the list as well as the GNOME
bug?

So it seems that also kde probably use this library to splice data from
a pipe, I saw that it seemed resolved in 2.6.36 but it is here again in
2.6.37.
I read your links, very good information.
I never know that kde was using this splice for copying things.
Sorry but I'm not member of kde bugzilla, I was simply searching for
information.
The problem is that only reiser4 exhibit this problem on my system so I
guessed that was a problem of this file system, this is the reason
because I didn't fill a bug on the other bugzilla.
Thanks,
Paolo
