2019-10-07Rename "hihglevel.h" to the more appropriate "common.h"David Oberhollenzer
It only contains helpers for _common_ stuff for all the utilities. The actual high level stuff has been moved to libsquashfs a while ago. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-10-07Improve ABI backward & forward compatibillityDavid Oberhollenzer
- Padd the compressor config union - 128 bytes aught to be enough for everyone, i.e. future compressors. - Insist that the padding space is initialized to 0. If a field gets added to an existing compressor, it can test for 0 as a sentinel value. - Add a size field to the hook structure, aka "the Microsoft way". - The explanation is in the comment. - Don't make the Microsoft mistake of checking for >=, insist on *exact* size match. Future users will need a fallback if their hooks are rejected. But at least they will be rejected instead of silently not being used. - Add an unsupported flag check to the dir tree reader. - Add a basic abi unit test that, for now, checks the size of the compressor config struct fields.

2019-09-27Cleanup: replace fixed with data types with typedefsDavid Oberhollenzer
This is a fully automated search and replace, i.e. I ran this: git grep -l uint8_t | xargs sed -i 's/uint8_t/sqfs_u8/g' git grep -l uint16_t | xargs sed -i 's/uint16_t/sqfs_u16/g' git grep -l uint32_t | xargs sed -i 's/uint32_t/sqfs_u32/g' git grep -l uint64_t | xargs sed -i 's/uint64_t/sqfs_u64/g' git grep -l int8_t | xargs sed -i 's/int8_t/sqfs_s8/g' git grep -l int16_t | xargs sed -i 's/int16_t/sqfs_s16/g' git grep -l int32_t | xargs sed -i 's/int32_t/sqfs_s32/g' git grep -l int64_t | xargs sed -i 's/int64_t/sqfs_s64/g' and than added the appropriate definitions to sqfs/predef.h The whole point being better compatibillity with platforms that may not have an stdint.h with the propper definitions.

2019-09-26Remove remnants of the old data writerDavid Oberhollenzer
- Move the statstics hooks to the rest of the statistics code - Used the new data writer directly in gensquashfs & tar2sqfs - Demote what is left to a helper function for processing an input file and submitting it to the new data writer Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-09-14Remove fstree file flagsDavid Oberhollenzer
As a side effect, this requires the data writer to keep track of statistics. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-14Move data deduplication from fstree code to data writerDavid Oberhollenzer

2019-08-31Split libsquashfs.a into low seperate librariesDavid Oberhollenzer
The idea is to make libsquashfs.a independend of libfstree.a, so it becomes a general purpose squashfs manipulation library. All the high level glue code for libfstree.a and utilites that are overly specific with to tools are moved to a seperate librarby. This commit makes the first step by moving the stuff with dependencies on libfstree to a seperate library. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
