Improve ABI backward & forward compatibillity

2019-10-07T10:22:05+00:00

- 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.

Fix lzma2 VLI filter testing

Starting out with 0, makes the loop condition evaluate to false and none of the filters are tested. Signed-off-by: David Oberhollenzer

Fix unwanted sign extension in lzma decompressor

2019-09-27T22:06:07+00:00

First extend the uint8_t to size_t, then do the arithmetic, otherwise there is an addtional implicit conversion to int, possibly resulting in unwanted sign extension. Signed-off-by: David Oberhollenzer

Remove use of ssize_t from library API

2019-09-27T16:43:07+00:00

ssize_t is only available on POSIX platforms and even there it is only defined to hold at least -1 in the range of negative numbers. This commit replaces ssize_t return types with sqfs_s32 and the coresponding function arguments with sqfs_u32. Because the range of positiv numbers for a signed 32 bit number is only half that of the unsigned version, additional checks have to be added. Signed-off-by: David Oberhollenzer

Cleanup: replace fixed with data types with typedefs

2019-09-27T16:15:40+00:00

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.
