I have discovered a few oddities with --relative in the latest
development rsync (from git, yay!):
#1. Junk in the middle of a source argument leads to duplicate entries
in the file list:
$ mkdir src src/D
$ rsync-dev -ni -rR ././src/.//.//.//.//.//.//.//./D/ dest/
cd+++++++++ src/
cd+++++++++ src/./
cd+++++++++ src/
cd+++++++++ src/./
cd+++++++++ src/
cd+++++++++ src/./
cd+++++++++ src/
cd+++++++++ src/./
cd+++++++++ src/
cd+++++++++ src/./
cd+++++++++ src/
cd+++++++++ src/./
cd+++++++++ src/
cd+++++++++ src/./
cd+++++++++ src/
cd+++++++++ src/./
cd+++++++++ src/D/
Without incremental recursion, the problem is less severe:
$ rsync-dev -ni -rR --no-i-r ././src/.//.//.//.//.//.//.//./D/ dest/
cd+++++++++ src/./
cd+++++++++ src/
cd+++++++++ src/D/
Rsync 2.6.9 gets this right:
$ rsync-2.6.9 -ni -rR ././src/.//.//.//.//.//.//.//./D/ dest/
cd+++++++ src/
cd+++++++ src/D/
#2. Rsync seems to have trouble accessing a source argument that begins
with ./.// :
$ ls -ld ././/src/
drwx------+ 3 matt matt 72 2007-10-30 19:32 ././/src/
$ rsync-dev -ni -rR ././/src/ dest/
rsync: link_stat "/src" failed: No such file or directory (2)
rsync error: some files could not be transferred (code 23) at
main.c(1053) [sender=3.0.0pre4]
Rsync 2.6.9 also fails, but differently:
$ rsync-2.6.9 -ni -rR ././/src/ dest/
rsync: opendir "/src" failed: No such file or directory (2)
cd+++++++ /src/
rsync error: some files could not be transferred (code 23) at
main.c(977) [sender=2.6.9]
#3. With incremental recursion, excluding an ancestor of a source
argument stops traversal of a source argument:
$ rsync-dev -ni -rR --exclude='/src' src/D/ dest/
(No output)
This happens even with --no-implied-dirs (!):
$ rsync-dev -ni -rR --no-implied-dirs --exclude='/src' src/D/ dest/
(No output)
When incremental recursion is turned off, rsync works correctly:
$ rsync-dev -ni -rR --no-i-r --exclude='/src' src/D/ dest/
cd+++++++++ src/D/
