2023-04-20Collect and print statistics about the kind of files we are packingDavid Oberhollenzer
Using depth-first search, we collect some crude statistics about directory tree types (e.g. regular files, directories, device special files and so on) and print them out after serializing the tree. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2023-04-20libfstree: Remove special modes for hard linksDavid Oberhollenzer
Instead of adding special sentinel modes, simply treat hard links as special case of symlinks, setting a flag to indicate that it is a hard link and another flag to indicate that it has been resolved. 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>
2023-04-12Win32: Fix fstree CLI mtime range checkDavid Oberhollenzer
On Windows, long is a 32 bit integer, so we cannot check if the long value is greater than UINT32_MAX. Instead, check if strtol sets errno. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2023-04-01libsquashfs: remove the default block writer alignment featureDavid Oberhollenzer
The idea of the block align feature was to allow micro-managing that some files are forcefully aligned to 1k/4k ("device block") boundaries, hoping to improve access time at the cost of data density. The feature was not exposed in the tools for a long time and eventuall added to the sort file. Measurement and experimentation showed, that it in fact worsened the read performance on a test system with an old micro SD card as the bottle neck. The feature is removed, and if needed, can be brought back simply by wrapping/sub-classing the default block writer, if need be..
