Files-from data is now sent as multiplexed I/O so that it can mingle
with any messages (such as debug output). Requires protocol 31.
Protocol 31 no longer disables output verbosity in a couple instances
that used to cause protocol issues.
Got rid of MSG_* messages that have implied raw data that follows after
them. We instead send a negative index value as a part of the raw data
stream, which is guaranteed to be output together with the following
data. This only affects the (in-progress) protocol 31 and the (self-
contained) communication stream from the receiver to the generator.
Added --debug=IO and improved --debug=FLIST. Some --debug=IO output
requires --msgs2stderr to be used to see it (i.e. sending a message
about sending a message would send another message, ad infinitum).
- Improve function name: parse_rule -> parse_filter_str (to make the
similarity with parse_filter_file clearer, and better indicate that
it can parse multiple rules when FILTRULE_WORD_SPLIT is specified).
- In preparation for rule prefixes containing information beyond the
rflags, change the code to pass around a full "template" filter_rule
instead of just rflags. Callers of parse_filter_{str,file} that want
to specify only rflags can use rule_template(rflags) .
- Remove the MODIFIERS_* strings and instead hand-code the condition
under which each modifier is valid. This should make it easier to
see that the conditions are correct.
- Tighten up default modifiers on merge rules:
- Disallow "!" because it isn't useful.
- If the merge rule specifies a side via "s" or "r", the rules in the
file cannot also specify a side via "s", "r", "hide", etc.
[Patch was changed by Wayne a bit prior to application.]
- Changed get_backup_name() to verify the backup path, and make any
missing directories. This avoids accidental use of a symlink as a dir
in a backup path, and gets rid of any other non-dirs that are in the
way. It also avoids the need for various operations to retry after
calling make_bak_dir(), simplifying several pices of code.
- Changed create_directory_path() to make_path(), giving it flags that
lets the caller decide if it should skip a leading slash or drop the
trailing filename.
- Mention when we create the backup directory, so the user is not caught
unaware when rsync uses a directory they didn't expect.
- Got rid of some dir-moving backup code that is not used.
- Added a little more backup-debug output.
- Implement --ignore-missing-args.
- In the absence of --*-missing-args, a missing source arg is an
FERROR_XFER, but doesn't need to be an IOERR_GENERAL.
- Revise the man page.
