libcommon: backport block processor API update

2021-01-19T10:04:33+00:00

The changes from commit 5191a25b92f903bcc2142be7ea1bfbe5ea1f5096 are backported here in a separate commit since master had some restructuring of libcommon.a after version 1.0.2 and the commit cannot be rebased directly. Signed-off-by: David Oberhollenzer

2021-01-19T09:45:59+00:00

This commit is an amalgamation of the commits on master that implement exact matching of fragment blocks during deduplication. Signed-off-by: David Oberhollenzer

libsqfs: implement exact matching in the default block writer.

2021-01-19T09:45:59+00:00

Instead of comparing (compresed, disk-size, checksum) tuples to find block matches, do an exact, byte-for-byte comparison of the data stored on disk to avoid the possibility of a spurious colision. Since this is the desired behaviour, make it the default, optionally overrideable through a flag. Signed-off-by: David Oberhollenzer

Cleanup: mark sqfs_xattr_writer_flush writer argument as const

2020-06-09T04:51:31+00:00

It does not make any changes to the writer itself, so mark it as const. This also requires some similar changes to the string table. Signed-off-by: David Oberhollenzer

Move the fragment deduplication hash table back into the block processor

2020-06-07T00:44:10+00:00

Fragment deduplication really doesn't belong into the public API of the fragment table. 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

lzma compressor: add support for the "extreme" flag
