2023-04-29gensquashfs: Move the scan_dir callback before creating the nodeDavid Oberhollenzer
This way, we can remove the discard_node function and simplify the scan_dir code further. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-04-29gensquashfs: Remove flag handling from scan_dirDavid Oberhollenzer
The logic was previously there to allow recursing into directories that exist in the fstree and the scanned directory, but not create new directories. Because the dir_tree_iterator_t supports reporting contents but not directories (and does DFS), we can simply check if the parent of the directory exists. Under normal DFS, it must exist, because we created it earlier. If we are skipping the directory entries, it only exists if it was there earlier and we can skip entries that have a non-existant parent, retainint the old behavior.

2023-04-29gensquashfs: Remove fstree_from_subdirDavid Oberhollenzer
It is only used in the glob function, so assemble the path there and jus tuse fstree_from_dir. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-04-29Move type based filtering to libutil dir_tree_iterator_tDavid Oberhollenzer
Limited unit testing for the flags is added, particularly the abillity to recurse into sub-directories, but not report the parents as individual entries. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-04-29gensquashfs: use stacked tree iterator in fstree_from_dirDavid Oberhollenzer

2023-04-21libutil: unix: simplify/unify directory iterator error handlingDavid Oberhollenzer
Instead of printing out error messages, return an errro ID and match the behavior with the Windows implementation. Also, don't check first if the struct stat says it is a link, the readlinkat() system call will fail if it isn't. Avoid confusing the deputy.

2023-04-21libutil: Add a method to the directory iterator to open a sub directoryDavid Oberhollenzer
This is also the reason we need to lug around the original directory path on Windows. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-04-19libfstree: get rid of dir_info_tDavid Oberhollenzer
The single boolean created_implicitly can be replaced with a general purpose flag field. The "children" pointer can then be hoisted directly into the data union of tree_node_t. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2023-04-12Merge Windows and Unix implementations of fstree_from_subdirDavid Oberhollenzer

2023-04-12Copy the dir scan pattern from the Windows implementationDavid Oberhollenzer
If we look at a sub directory, piece totether the full path and open that instead. This allows us to move the directory open into the scan function and get rid of the dirfd trickery. Also pull the recusion step out into the parent function. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
