Summary: rsync of symlinks on >=bsd needs lutimes(2) and
lchmod(2)
Product: rsync
Version: 2.6.5
Platform: All
OS/Version: FreeBSD
Status: NEW
Severity: normal
Priority: P3
Component: core
AssignedTo: wayned at samba.org
ReportedBy: rsync at cpe-24-95-91-210.columbus.res.rr.com
QAContact: rsync-qa at samba.org
on at least freebsd, symlinks have settable
times/perms as well as u/g/flags.
true, use of a symlink is time/perm/u/g/flag agnostic
however, unsynchronized time/perm do cause problems
elsewhere on systems that have the above syscalls. ie:
1 - find <path> -newer <stampfile> -ls
print if any/all types, rather than a single, are newer
2 - find <path> -perm +7022 -ls
print if any/all types, rather than a single, are not isolated
rsync created slinks earn the time of the symlink(2) call
by rsync. further, an lutimes(2) run elsewhere against the
slink is not picked up by later rsync runs. both break ex1.
similarly, rsync ignores both umask and src perms when
creatings slinks. neither are updated in later runs. breaking ex2.
rm -r ./dstdir
srcdir:
lrwxrwx--- 1 u g 1 Jul 24 03:29:58 2005 a -> b
-rw-r----- 1 u g 0 Jul 24 03:29:58 2005 b
prw-rw---- 1 u g 0 Jul 24 03:29:58 2005 fifo
srwxrwx--- 1 u g 0 Jul 24 03:29:58 2005 sockfile
umask 0022
[root] rsync -axv --delete ./srcdir/ ./dstdir/
dstdir:
lrwxrwxrwx 1 u g 1 Jul 24 03:30:36 2005 a -> b
-rw-r----- 1 u g 0 Jul 24 03:29:58 2005 b
prw-rw---- 1 u g 0 Jul 24 03:29:58 2005 fifo
srwxrwx--- 1 u g 0 Jul 24 03:29:58 2005 sockfile
last time i looked this required passing the
source stat structure through to the affected
rsync functions and extending the fn to use it
with the above syscalls, perhaps ifdef'd if not
present.
reply only to bugzilla/rsync list, thx.
