Generate linear file list in fstree

2019-07-25T20:10:24+00:00

Instead of doing DFS on the fly in gensquashfs, churn out a linked list of all files in an archive. Future improvements in packing strategies can go into this file. This can also be usefull for other purposes in the future, such as file deduplication or as a work queue for the unpacker. Signed-off-by: David Oberhollenzer

cleanup: remove atime/ctime processing code

2019-07-24T11:46:05+00:00

This commit removes all the code for parsing and processing atime/ctime and values and related test code. Caring about those is kind of pointless because squashfs can only store mtime in inodes. The only relevant place is when generating a struct stat from a squashfs inode or an fstree node. Signed-off-by: David Oberhollenzer

Enable largefile support

2019-07-24T07:16:16+00:00

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. Signed-off-by: Matt Turner Signed-off-by: David Oberhollenzer

Add a way to optionally keep the original time stamps

2019-07-22T15:12:45+00:00

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.

Cleanup xattr handling

2019-07-21T13:44:02+00:00

- Store them in a struct instead of a hacky uint64_t with magic shifts - Split up key/value pair write function to write_key and write_value - Move the size accounting into those functions respectively Signed-off-by: David Oberhollenzer

Keep track of xattr key & value references AFTER deduplication

2019-07-21T11:30:34+00:00

This commit adds a reference count functionality to the string table implementation and uses this functionality in the fstree code to count how often each key and value is referenced by the deduplicated Xattr blocks. This is needed to support deduplication through out-of-band storage of xattrs. Signed-off-by: David Oberhollenzer

fstree: add support for spaces in filenames

2019-07-17T09:05:42+00:00

This commit adds a mechanism to fstree_from_file to support filenames with spaces in them by quoting the entire string. Quote marks can still be used inside file names by escaping them with a backslash. Back slashes (if that is your thing) can also be escaped. Signed-off-by: David Oberhollenzer

fstree: mknode: initialize fragment data, add extra blocksize slot

2019-07-12T13:44:14+00:00

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
