Replace reads in squashfs with positional reads

2019-07-25T12:20:48+00:00

In most cases, we know exactely where the data that we want to read is on disk, so instead of using read() on the squashfs (or lseek + read), the code can in many places be cleaned up to use the pread wrapper read_data_at instead. Signed-off-by: David Oberhollenzer

Include the reason ZSTD gave us for the error

2019-07-24T07:17:30+00:00

Without it you're left guessing or using a debugger to figure out what's wrong. Signed-off-by: Matt Turner Signed-off-by: David Oberhollenzer

Enable largefile support

2019-07-24T07:16:16+00:00

Requires that config.h be included before other headers, since the macro _FILE_OFFSET_BITS changes the definitions of things like 'struct stat'. I chose to simply include it at the top of every C file and at immediately after the double-inclusion guards of every header. Signed-off-by: Matt Turner Signed-off-by: David Oberhollenzer

cleanup: move error handling into read_retry

2019-07-16T20:48:00+00:00

If read_retry fails to read the expected amount of data (EOF or otherwise), it is almost always an error. This commit renames read_retry to read_data and moves error handling into the function, making a lot of error handling code redundant. Signed-off-by: David Oberhollenzer

cleanup: move error handling into write_retry

2019-07-16T20:47:59+00:00

If write_retry fails to write everything, it is *always* an error. This commit renames write_retry to write_data and moves error handling into the function, making a lot of error handling code redundant. Signed-off-by: David Oberhollenzer

Fix memory leak in gzip compressor

Don't allocate the compressor structure twice. Bug found using scan-build. Signed-off-by: David Oberhollenzer

Move all handling of compressor names to libcompress.a

2019-06-23T00:37:08+00:00

This commit removes handling of compressor names from gensquashfs. Instead, functions are added to libcompress to obtain name from ID, ID from name and to print out defaults. Signed-off-by: David Oberhollenzer

Cleanup dependency handling

2019-06-11T13:06:28+00:00

Always try to gather all compressor libraries available, but only complain about missing a one if it has been *explicitly* selected. If a compressor has been explicityl disabled, we can still turn it off after checking. Also, rework gensquashfs to set the default compressor based on what's available.
