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: move error handling into write_retry

2019-07-16T20:47:59+00:00

If write_retry fails to write everything, it is *always* an error. This commit renames write_retry to write_data and moves error handling into the function, making a lot of error handling code redundant. 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).

Fix: tar2sqfs move skip for invalid name first

2019-07-04T17:37:01+00:00

If the name is missing or invalid, set the skip flag to true to skip the tar record and use the same skip logic as for the others. Signed-off-by: David Oberhollenzer
