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 unneccessary conditionals from automake files

2019-07-25T20:07:32+00:00

If some library isn't present, the variable $(FOO_LIBS) simply evaluates to empty string, so it can be simply be added to LDADD without any checks. Signed-off-by: David Oberhollenzer

cleanup: remove some redundant header inclusions

2019-07-25T20:01:47+00:00

The utility programs pretty much all have the same structure of including one central header per C file that includes all required library headers, so we can simply include config.h which we need for large file support from there and remove it from the C files. 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.

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

Add flags to data writer to micro manage behaviour

2019-07-15T12:47:03+00:00

The added flags allow controlling the following on a per file level: - forcing a file to be written uncompressed - forcing a file to not have a fragment, i.e. the last truncated block actually being written as a block - padding a file to be alligned to device block size The flags are not yet exposed to anything user controllable (such as command line flags).

gensquashfs: Remove rest of read_number from options parser

2019-06-23T08:32:13+00:00

Use a simple strtol for block size and device block size: - We don't need to check the block size, sqfs_super_init does that. - We only need to make sure the device block size is at least 1k. Signed-off-by: David Oberhollenzer
