- Add -L to walk the tree `logically', by following symbolic links in
the heirarchy.
- Add -P to walk the tree `physically'. This is the current behaviour,
and the default.
- Add "-X excludes-file" to give mtree the ability to exclude files and
directories from its traversal. excludes-file contains fnmatch(3)
patterns to exclude from the walk.
- Add "md5digest" synonym for "md5".
- Add "rmd160" keyword for RMD-160 message digest, and "rmd160digest" synonym.
- Add "sha1" keyword for SHA-1 message digest, and "sha1digest" synonym.
- Don't try to compare() other attributes if the type doesn't match;
it's nothing but trouble, and no use anyway.
- In -c, only emit "/set" records if something has changed since the
previous one.
User interface changes by me:
- Check a device's parameters before checking uid/gid/mode.
- If updating (-u), modify the following to match the specification:
- Device type (retaining existing ownership).
- Symlink target.
Fixes from (or inspired by) FreeBSD:
- Use p->ftslevel instead of own code to keep track of the level ourself.
The previous code got majorly confused if fts(3) couldn't descend
into a subdir, resulting in leaf nodes getting attached to the wrong
directory.
XXX: This new method is much much more robust, even though it's not 100%
perfect; it might result in a couple of following entries in the spec
to be incorrectly tagged as missing.
- Pass a useful pathname to rlink(), so that logical (-L) traversal
doesn't confuse symlink checking.
- Consistently use MAXPATHLEN+1 sized buffers for pathnames, so that
there's room for the NUL.
- Use mtree_err() and strerror(p->fts_errno) to report errors during
the fts(3) walk.
Fixes by me:
- Remove now-unused `const char *name' argument from compare().
- Change crc_total from an int to a u_int32_t, to match usr.bin/cksum/crc.c.
- Remove trailing whitespace.
- Remove unnecessary (void) casts on functions.
- Reorder entries in the getopt() switch.
- Replace strtoq() with strtoll(), and use strtoul() appropriately.
- Renumber F_ flags to be in alphabetical order.
- fix the loaned case in uvm_pagefree().
- redo uvmexp.swpgonly accounting to work with page loaning.
add an assertion before each place we adjust uvmexp.swpgonly.
- fix uvm_km_pgremove() to always free any swap space associated with
the range being removed.
- get rid of UVM_LOAN_WIRED flag. instead, we just make sure that
pages loaned to the kernel are never on the page queues.
this allows us to assert that pages are not loaned and wired
at the same time.
- add yet more assertions.
pages loaned to the kernel. this implies that we also need to
call pmap_kremove() before uvm_km_free().
other general cleanup: remove argument names from prototypes,
rename some variables, etc.
