This patch avoids inconsistent evaluation of options in the
show_filelist_p() function by turning it into a var. We
also avoid setting "output_needs_newline" if --quiet was
specified.
If the receiving side cannot hard-link symlinks and/or special files
(including devices) then we now properly handle incoming hard-linked
items (creating separate identical items).
If the receiver gets a filename with a leading slash (w/o --relative)
and/or a filename with an embedded ".." dir in the path, it dies with
an error (rather than continuing). Those invalid paths should never
happen in reality, so just reject someone trying to pull a fast one.
If the receiver is running without --relative, it shouldn't be receiving
any filenames with a leading slash. To ensure that the sender doesn't
try to pull a fast one on us, we now make flist_sort_and_clean() strip a
leading slash even if --relative isn't specified.
The I/O code can receive incremental file-list chunks during deletion,
and their OPT_EXTRA fields would get corrupted when file_extra_cnt is
incremented.
Instead of temporarily enabling uid_ndx to find out whether the user
owns a file, have make_file() set a flag for that purpose.
Applied with a few minor tweaks by Wayne. Fixes bug 7936.
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).
Since the value is not needed, protocol 31 no longer sends it, while
older protocols are optimized so the sender just sends a valid rdev
value as efficiently as possible. The receiver no longer caches an
rdev value for special files, and the generator will always pass a 0
rdev value to do_mknod() for special files. Fixes bug #6280.
- 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.
