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>
2023-04-29libutil: Add a stacked, recursive directory tree iteratorDavid Oberhollenzer
The concept is simple: Use the existing, platform dependent iterator to walk a directory. If a directory entry is encountered, recurse into it using the open_subdir handler, reconstruct the full path for any entries discovered using the directory stack. An additional function is added to skip a sub-hierarchy. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
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>
2023-04-21libutil: win32: clenaup dir iterator initialization, retain the pathDavid Oberhollenzer
Instead of dropping the path immediately, store it inside the structure. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
