this prevents a second interrupted transfer from reducing the size of
the transferred file.
- set SIGUSR1 to SIG_IGN early to prevent a race condition that
prevents the --partial code from working properly
temporary files were being created with the same permissions as the
original file. So if the file was setuid but not owned by the user
doing the transfer then there was a window of opportunity for a
malicious user to execute it with the wrong permissions while it was
being transferred.
Thanks to snabb@epipe.fi for pointing this out.
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.
