Add support for repacking condensed sparse files

2019-06-30T14:41:21+00:00

This commit broadly does the following things: - Rename and move the sparse mapping structure to libutil - Add a function to the data writer for writing condensed versions of sparse files, given the mapping. - This shares code with the already existing function for regular files. The shared code is moved to a common helper function. - Add support to tar2sqfs for repacking sparse files. Signed-off-by: David Oberhollenzer

Add support for packing sparse files

2019-06-28T13:07:34+00:00

This commit adds support for packing sparse files into squashfs images as follows: - In the data writer: simply detect zero blocks and write a zero to the block size field and don't emit any data. Record the number of bytes saved this way. For fragments, set the fragment offset to invalid. - In the inode writer: write out the number of bytes saved for sparse files. If there should be a fragment but there is none, append a block count of 0. - In the data reader: if the block size is 0, read nothing from disk and emit an empty block. Do the same if the fragment is missing. - In the inode reader: restore the number of bytes saved for sparse files. The sparse files can be packed and unpacked, but the unpacking will not create sparse files for now. Signed-off-by: David Oberhollenzer
