Add support for repacking condensed sparse files2019-06-30T14:41:21+00:00David Oberhollenzerdavid.oberhollenzer@sigma-star.at2019-06-30T14:41:21+00:00urn:sha1:f439b20706ade4b5630c3d6c57e6a36ce0dc287a
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.

Add support for packing sparse files2019-06-28T13:07:34+00:00David Oberhollenzerdavid.oberhollenzer@sigma-star.at2019-06-28T10:41:26+00:00urn:sha1:4e017928c7b5b590d2c7e04e42cb497eb3a4f8cf
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.
