Cleanup: move zlib/lz4 code from lib/sqfs/comp/ to lib/

2020-08-04T17:27:42+00:00

The source code of a modified liblz4 and zlib are included with the option to compile them into libsquashfs if they are not available on the system. So far, the source code was included directly in the compressor sub directory within libsqsuashfs. This commit moves the libraries out into the lib directory. 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

Fix: zstd: actually set the compression level from the options

2020-05-21T19:24:28+00:00

In the zstd compressor, the compression level from the configuration structure wasn't used at all. Instead, the zstd compressor was told to use level 0 and compressor options with that parameter were written to disk. This commit makes sure the level parameter is propperly initialized.

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

Fix build of lz4 compressor with older versions of liblz4

2020-03-18T21:30:17+00:00

Older versions of liblz4 don't define LZ4HC_CLEVEL_MAX. This commit adds a definition if liblz4 doesn't provide one. Signed-off-by: David Oberhollenzer

Change the signature of sqfs_compressor_create to return an error code

2020-03-05T21:41:04+00:00

Make sure the function has a way of telling the caller *why* it failed. This way, the function can convey whether it had an internal error, an allocation failure, whether the arguments are totaly nonsensical, or simply that the compressor *or specific configuration* is not supported.
