2019-07-28Fix missing initialization of file fragment fieldsDavid Oberhollenzer
Despite having a flag for that now, they still need to be initialized because they are written straight to disk. Fixes: d4d1854aaed867d28ebfc97afb3518254ab6fd4b Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-07-28Add general purpose flags field to file_info_tDavid Oberhollenzer
Simplifies some task if we can just add a flag that a file has a framgent or that it has already been detected as a duplicate. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-07-24Enable largefile supportMatt Turner
Requires that config.h be included before other headers, since the macro _FILE_OFFSET_BITS changes the definitions of things like 'struct stat'. I chose to simply include it at the top of every C file and at immediately after the double-inclusion guards of every header.

2019-07-22Add a way to optionally keep the original time stampsDavid Oberhollenzer
First of all, this commit adds a mod_time field to a tree node. When creating the tree node, the field is set from the struct stat. When scanning a directory, the time stamps from the input are used if set. Second, the libsqfs code that reads inodes is modified to store the mod_time from the inode in the fstree node and to write the tree node into a generated inode. Finally, tar2sqfs is modified to optionally keep the timestamps from the tar archive instead of setting defaults. gensquashfs is similarly modified to keep the input timestamps if specified. The result is as follows: - sqfs2tar will always carry the timestamps from the squashfs over to the tar ball. - tar2sqfs will set defaults, unless explicitly asked to preserve the mtime from the tar ball. - gensquashfs can optionally preserve the mtime from the input hierarchy it processes if only --pack-dir is specified.

2019-07-12fstree: mknode: initialize fragment data, add extra blocksize slotDavid Oberhollenzer
This commit makes sure that regular file tree nodes have one more slot than necessary to support files that don't have fragments. Also, it initializes the fragment data, which should help to deduplicate some code ahead. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
