[Pkg-libburnia-devel] Bug#738359: xorrisofs: -follow-links fails on valid symlinks

[Michael Gold]

Package: xorriso
Version: 1.3.2-1
Severity: important

I have a tree of symlinks, pointing into git-annex repositories, that
causes xorrisofs to fail when using the -follow-links option.  strace
shows that it uses lstat and then tries to resolve the link itself,
incorrectly.  It shouldn't be necessary to use lstat or readlink in
-follow-links mode; stat and open will follow links automatically.

These commands cause a similar failure:
	mkdir a b root
	echo data > b/test
	ln -s ../b/test a/test
	ln -s ../a/ root/a
	# "cat root/a/test" shows the link is valid
	xorrisofs -f -o test.iso root/
Output:
	xorriso 1.3.2 : RockRidge filesystem manipulator, libburnia project.

	Drive current: -outdev 'stdio:test.iso'
	Media current: stdio file, overwriteable
	Media status : is blank
	Media summary: 0 sessions, 0 data blocks, 0 data,  409g free
	xorriso : FAILURE : Cannot obtain link target of : '/xr0/michael/x/lntest/root/a/test' : No such file or directory
	xorriso : NOTE : Problem occured with intermediate path : '/xr0/michael/x/lntest/root/b/test'
	xorriso : aborting : -abort_on 'FAILURE' encountered 'FAILURE'
