had a fundamental flaw in the way it detected duplicate deletion
scanning (which is very important when -R is used). I now store
inode/device numbers and use those to do the detection. This should be
a much less fragile method.
turned up before because Linux had a bug in the handling of NULL
pointers to read()/write() on pipes, so I never noticed the bug in my
testing.
I've also sent a patch to Linus.
as not being able to open a directory) this flag is set and propogated
to the other end. When this flag is set the --delete code is
disabled. This prevents the problem that io or permission errors could
cause files to be incorrectly deleted on the destination.
- added a --timeout option. This allows you to set an IO timeout in
seconds. If no io occurs in that time then rsync exits with a timeout
error.
- changed some FERROR fds to FINFO
points but not their contents.
I did this by calling stat() on the directory above the current
directory and checking to see if it has the correct st_dev. Hopefully
this will work for most systems.
Note that the permissions and ownership on the mount point cannot be
copied correctly as they are unavailable while the filesystem is
mounted. Instead rsync will set the permissions and ownership to those
of the root directory of the mounted filesystem (ie. the apparent
permissions/ownership of the directory)
This options tells rsync to delete directories even if they are not
empty. This applies to both the --delete option and to cases where
rsync tries to copy a normal file but the destination contains a
directory of the same name. Normally rsync will refuse to do a
recursive directory deletion in such cases, by using --force the
recursive deletion will be done.
files up to 2^64 bytes in size. Now I just need to find enough disk
space to test this :-)
The 64 bit offset code only works if off_t is 64 bits (or bigger!) on
both ends of the link. If one end tries to send a file greater than
2^31 in size and the other end doesn't support it then rsync will
abort.
This commit also cleans up some static declarations so they are in a
unitinitialised segment to save load time.
