[Libguestfs] [PATCH 2/2] actions: turn some params into RelativePathnameList (RHBZ#1174551).
Use RelativePathnameList as type for lists of relative paths, as used in some listing-alike APIs. This way we can ensure absolute paths in those lists are rejects outright. As a consequence, test-big-dirs.pl does not need to prepend the directory name anymore before calling listing-alike APIs: previously they didn't fail, but the returned lists contained only invalid elements (and only their size was checked). --- generator/actions.ml | 14 +++++++------- tests/bigdirs/test-big-dirs.pl | 1 - 2 files changed, 7 insertions(+), 8 deletions(-) diff --git a/generator/actions.ml b/generator/actions.ml index 274ef3f..a6de484 100644 --- a/generator/actions.ml +++ b/generator/actions.ml @@ -2655,7 +2655,7 @@ See also C<guestfs_write>." }; { defaults with name = "lstatlist"; added = (1, 0, 77); - style = RStructList ("statbufs", "stat"), [Pathname "path"; StringList "names"], []; + style = RStructList ("statbufs", "stat"), [Pathname "path"; RelativePathnameList "names"], []; deprecated_by = Some "lstatnslist"; shortdesc = "lstat on multiple files"; longdesc = "\ @@ -2675,7 +2675,7 @@ for getting extended attributes." }; { defaults with name = "lstatnslist"; added = (1, 27, 53); - style = RStructList ("statbufs", "statns"), [Pathname "path"; StringList "names"], []; + style = RStructList ("statbufs", "statns"), [Pathname "path"; RelativePathnameList "names"], []; shortdesc = "lstat on multiple files"; longdesc = "\ This call allows you to perform the C<guestfs_lstatns> operation @@ -2694,7 +2694,7 @@ for getting extended attributes." }; { defaults with name = "lxattrlist"; added = (1, 0, 77); - style = RStructList ("xattrs", "xattr"), [Pathname "path"; StringList "names"], []; + style = RStructList ("xattrs", "xattr"), [Pathname "path"; RelativePathnameList "names"], []; optional = Some "linuxxattrs"; shortdesc = "lgetxattr on multiple files"; longdesc = "\ @@ -2719,7 +2719,7 @@ for getting standard stats." }; { defaults with name = "readlinklist"; added = (1, 0, 77); - style = RStringList "links", [Pathname "path"; StringList "names"], []; + style = RStringList "links", [Pathname "path"; RelativePathnameList "names"], []; shortdesc = "readlink on multiple files"; longdesc = "\ This call allows you to do a C<readlink> operation @@ -7703,7 +7703,7 @@ yourself (Augeas support makes this relatively easy)." }; { defaults with name = "internal_lxattrlist"; added = (1, 19, 32); - style = RStructList ("xattrs", "xattr"), [Pathname "path"; StringList "names"], []; + style = RStructList ("xattrs", "xattr"), [Pathname "path"; RelativePathnameList "names"], []; proc_nr = Some 205; visibility = VInternal; optional = Some "linuxxattrs"; @@ -7733,7 +7733,7 @@ into smaller groups of names." }; { defaults with name = "internal_readlinklist"; added = (1, 19, 32); - style = RStringList "links", [Pathname "path"; StringList "names"], []; + style = RStringList "links", [Pathname "path"; RelativePathnameList "names"], []; proc_nr = Some 206; visibility = VInternal; shortdesc = "readlink on multiple files"; @@ -12220,7 +12220,7 @@ This is the same as the L<lstat(2)> system call." }; { defaults with name = "internal_lstatnslist"; added = (1, 27, 53); - style = RStructList ("statbufs", "statns"), [Pathname "path"; StringList "names"], []; + style = RStructList ("statbufs", "statns"), [Pathname "path"; RelativePathnameList "names"], []; proc_nr = Some 423; visibility = VInternal; shortdesc = "lstat on multiple files"; diff --git a/tests/bigdirs/test-big-dirs.pl b/tests/bigdirs/test-big-dirs.pl index 40038b7..5bcc71c 100755 --- a/tests/bigdirs/test-big-dirs.pl +++ b/tests/bigdirs/test-big-dirs.pl @@ -63,7 +63,6 @@ for (my $i = 0; $i < $nr_files; ++$i) { # Check that lstatlist, lxattrlist and readlinklist return the # expected number of entries. my @a; -@filenames = map { "/dir/$_" } @filenames; @a = $g->lstatlist ("/dir", \@filenames); die unless @a == $nr_files; -- 2.1.0

That is to say: is "foo/bar" permitted, or just "bar"?
