libsqfs: Add a sqfs_block_processor_create_ex function

2021-01-19T03:03:37+00:00

This function creates a block processor from a structure describing it. A stub implementation for the old sqfs_block_processor_create is added that simply sets up such a struct and forwards the call. The current version of the description struct only contains the exact same parameters and a size field at the beginning. This approach is supposed to make extending the range of parameters easier without breaking ABI compatibillity. Currently already planned are: - Adding a sqfs_file_t pointer to double-check when deduplicating fragments. - When the scanning code reaches a usable state, add the abillity to pass scanned fragment data, so the block processor can be used for appending to an existing image.

libsqfs: implement exact matching in the default block writer.

2020-12-05T23:42:32+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

Cleanup: Add defines for minimum and maximum block size

2020-06-03T15:40:17+00:00

This commit adds propper defines in the super block header and removes some of the hard coded constants. Signed-off-by: David Oberhollenzer
