Cleanup: libcommon: use global LUTs for compressor options

2020-06-04T08:29:58+00:00

Instead of the convoluted logic, simply use a small number of LUTs that point to the available compressor flags for each compressor, the avaialble options and their ranges. Signed-off-by: David Oberhollenzer

Cleanup: Pull compression level parameter out into compressor config

2020-06-04T05:24:52+00:00

Every compressor (except LC4) has a compression level parameter. This commit pulls the compression level field out into the generic configuration structure and applies some code clean ups as a result from this. Signed-off-by: David Oberhollenzer

lzma compressor: support micro management options

2020-06-04T02:57:08+00:00

The LZMA compressor (through the xz-utils library) supports basically the same options for micro management as the XZ compressor. This commit enables support for those options in the compressor, the option parser and adds an option field to the configuration structure. Signed-off-by: David Oberhollenzer

Support associating a user pointer with data blocks

2020-05-29T16:24:25+00:00

This commit modifies the block processor to support associating a user data pointer with data blocks that it forwards to the block writer, which is modified to accept an optional user data pointer. Signed-off-by: David Oberhollenzer

Turn the sqfs_block_writer_t into an interface

2020-05-29T01:39:57+00:00

This way, everything that could be done through the hooks (and more) can be done by simply providign a custom implementation. The result is a lot clener that the previous hook based version. Signed-off-by: David Oberhollenzer

cleanup: libsqfs: eliminate block writer statistics

2020-05-29T01:39:57+00:00

- the "bytes submitted" can be moved over to the block processor - the number of blocks submitted are already there (implcitily, by adding the data block count to the fragment block count) - actual data bytes written can be computed from the super block - the remaining block count can be changed to simple counter that can be obtained through a function.

Expose more fine grained control values & flags on the XZ compressor

2020-05-04T14:57:43+00:00

This patch allows external users to fiddle with the XZ compressors compression strength, alignment and other values. Signed-off-by: David Oberhollenzer

tar2sqfs & gensquashfs: Delete the output file on failure

2020-04-16T03:17:29+00:00

This commit changes the tar2sqfs & gensquashfs code to pass the exit status on to sqfs_writer_cleanup in libcommon. The function sqfs writer code in libcommon is changed to retain the output file name and delete it if the status passed to the cleanup function is anything other than EXIT_SUCCESS.
