we no longer use non-blocking IO, instead it uses select a lot more,
being careful to always allow for reading whenever a valid read fd is
available and chcking timeouts.
also split the file io calls into fileio.c
messages from the server when using the socket code.
I've doen a fair bit of testing and I don't seem to have broken
anything, but it is a very complex change. More testing needed!
that it appears hidden while being transferred. This should be useful
when using rsync for mirroring so users accessing via ftp don't get
confused by the temporary files.
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.
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
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.
in 3 ways:
1) the realloc is done on a list of pointers, not a list of structures
2) only the basename of the file is now kept in the file struct an a
util function f_name() is now used to access the full name when
required.
3) pointers to directory names are re-used
hopefully I haven't broken anything. This will need lots of testing.
patches or wrappers. One problem with this is that rsync was not
written with this in mind and wasn't very careful about possible stack
overflows etc which could lead to security breaches. This wasn't a
problem when run in the traditional way as any user that can run rsync
can login anyway and cause much more damage that way.
This patch attempts to close possible stack overflow problems. I've
checked for all strcpy(), strcat(), sprintf() and memcpy()
overflows. I would appreciate it if someone else with a devious mind
could also go through the rsync source code and see if there are any
other stack overflows possible. Let me know if you do.
- by popular demand I have changed the behaviour of the --delete
option. It should now work as "expected" for even those people silly
enough not to read the man page. rsync will now only look for
candidate files/directories to delete in directories that are
explicitly transferred from the sender
- updated the README a bit
- try to fail a bit more gracefully when rsync runs out of disk
space. I don't think this issues is fully resolved yet
suggested on the list recently. See the man page entry for details but
basically it changes the behaviour so that paths are not stripped,
thus allowing you to specify a single rsync command to sync lots of
directories/files while preserving the full path name of each file.
also fixed a bug in the handling of umasks when both the source and
destination machines are local. We need to reset the umask before the
exec to ensure that the child gets a correct umask.
- handle directory ownership and permissions much better.
- fix bug where links caused the permissions of files to be
set incorrectly
- override the default umask in setting file permissions
- better handling -o and -D being passed to non-root users
- handle rsync to a destination of /
- fix the handling of mismatched file types at either end of the
link. For example, if the destination is a link and the source is not.
