I looked at the patch again and found some problems with it:
this code will remove host info from uri if relative path has a lot of
'..'
So i tried another way (it is only an example, so I hard-coded base &
escaped vars):
=================================================================================
gchar *base = "http://www.somehost.com/path/to/file";;
gchar *escaped = "../../../../../relative";
const char *resolved_relative_uri_path;
GnomeVFSURI *base_uri;
GnomeVFSURI *resolved_relative_uri;
base_uri = gnome_vfs_uri_new(base);
if (base_uri == NULL)
return 1;
resolved_relative_uri = gnome_vfs_uri_append_string(base_uri,
escaped);
uri_path = gnome_vfs_uri_get_path (resolved_relative_uri);
/* Complex part, I'll explain later
*/
if (resolved_relative_uri_path[0] != GNOME_VFS_URI_PATH_CHR) {
gint offset = 0;
if (resolved_relative_uri_path[0] == '.'
&& resolved_relative_uri_path[1] == '.')
offset += 2;
if (uri_path[offset] == GNOME_VFS_URI_PATH_CHR)
offset += 1;
gchar *tmp_path = resolved_relative_uri->text;
resolved_relative_uri->text =
g_strconcat(GNOME_VFS_URI_PATH_STR, tmp_path + offset, NULL);
g_free(tmp_path);
}
uri = gnome_vfs_uri_to_string(resolved_relative_uri,
GNOME_VFS_URI_HIDE_NONE);
gnome_vfs_uri_unref(base_uri);
gnome_vfs_uri_unref(resolved_relative_uri);
=================================================================================
I think that some explanations needed:
Why do we need this complex part?
If we try to call gnome_vfs_uri_append_path(...) with supplied values
uri will contain:
http://www.somehost.com../relative
I don't think this is what we wanted...
This happens when the number of '..' is odd and it is greater then
number of dirs
in /path/to/file. if the number of '..' is even, then we will get:
http://www.somehost.comrelative
The problem with this code is that it uses uri->text, because I haven't
found something like gnome_vfs_uri_set_path(...)
If it is OK for private function, I will create patch. If not, how can I
do the same thing
(changing path without touching other parts of uri) with public or
private functions?
