name-list. On POSIX systems, this list will be sorted with the user
names first, so the code will work essentially the same way it did
before for the currently supported OSes. However, the code will now
more easily support non-POSIX ACL setups such as (hopefully) the one
used in OS X.
- Increased the (potentially) available access-bit storage for name
elements from 3 to 31 bits. For non-name elements, the access bits
now have the potential to store 7 bits instead of 3. (All the
current POSIX implementations still error-check their values at 3
bits, but this will allow adding non-POSIX ACL setups more easily.)
- The protocol that transmits the ACL information was changed to send
names in a single list, and to use {read,write}_varint() functions
instead of {read,write}_byte(). This supports sending access-bit
values up to 32-bits (minus any bits reserved for xmit flags).
- The construction of the internal access-bit value was moved into the
lib/sysacls.c code, so that it could be handled in an appropriate
manner for each OS.
(Aside: the code still does not support transmitting incompatible ACL
information between systems, but I envision improving --fake-super to
store the ACL information that is received as xattr information, and
this would allow a system that supports extended attributes to backup
a source system that had an incompatible ACL method.)
non-name element.
- Set a define when the OS needs the name-list sorted.
- Got rid of the permset-related defines.
- Got rid of some function prototypes that rsync doesn't need.
- Got rid of the defines for the do-nothing ACL code.
call. This allows the per-OS compatibility code to construct the
value with however many bits are supported by each OS.
- Removed several functions that rsync doesn't (and won't) need.
- Got rid of the do-nothing ACL code (the ACL code in rsync should be
disabled on a system that we can't support).
- Made recv_file_entry() name the xmit-flags variable "xflags" to
prevent confusion with the internal flags value we're creating.
- Added an arg to the calls of recv_group_name() and match_gid().
- Use the improved function names: send_id_list() and recv_id_list().
- Improved the display of the GID values in output_flist().
- Added a uint16 flags var to struct iflist.
- We now mark a group with FLAG_SKIP_GROUP if the receiving user
can't set a group rather than turning it into GID_NONE. This
allows us to keep the real group ID mapping, which is needed by
the ACL code.
- Renamed push_flist_dir() to push_pathname().
- Set a pool var in recv_file_ent() instead of playing games with flist.
- Simplified the top_flags computation in send_file_list().
