2019-09-28Fix dir writer size accountingDavid Oberhollenzer
Count the *corrent* entry structure size, i.e. the on-disk one, not the in-memory one. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-28Fix dir writer: the index size is stored off-by-oneDavid Oberhollenzer

2019-09-27Add a header for platform compatibillity fluffDavid Oberhollenzer
- We don't have "endian.h" everywhere. On some BSDs its in sys and on some BSDs the macros have different names. - We definitely don't have sysmacros.h on non-Unix-like systems. - Likewise for sys/types.h, sys/stat.h and their contents.

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.

2019-09-09Change license of libsquashfs.soDavid Oberhollenzer
This this commit, the code that is compiled and linked to produce libsquashfs.so (and *only* libsquashfs.so) is released under the terms and conditions of the GNU Lesser General Public license, allowing 3rd party programs to dynamically link against it and still being able to release their programs under a license of their choosing. The libutil library is also relicensed, because it is statically linked into libsquashfs.so. This does not affect the command line programs that remain under the GPLv3. At the current time, the two libraries do not contain any 3rd party contributions and thus do not require anybodys consent other than mine to change the licensing terms (unlike e.g. libfstree.a). The libfstree.a and libsqfshelper.a utility libraries will also remain under the GPLv3 license. Going forward, some parts of libsqfshelper.a will be moved to libsquashfs.so. The parts absorbed by libsquashfs.so will then also have their licensing conditions changed *at that time*. For the public headers, this commit adds the full boiler-plate comment about the license, for the source files and internal headers, only the SPDX identifier is changed.

2019-09-07Remove printing to stderr in libsquashfs with returning error numbersDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-07Move data structure forward declarations to predef headerDavid Oberhollenzer
This in turn allows for removing most of the header inclusions within the public headers. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-05Fix API visibility for libsquashfs.soDavid Oberhollenzer
This commit adds a "predef.h" header to libsquashfs that exposes two macros, SQFS_API and SQFS_INTERNAL that are used to explicilty set the visibiliy of stuff that ends up in libsquashfs to default or hidden. For compatibillity with Windows which may at some point eventually be considered, the SQFS_API define is set to dllexport IF the cpp symbol SQFS_BUILDING_DLL is defined and set to import otherwise.

2019-09-04Add fstree independend directory writer to libsquashfs.soDavid Oberhollenzer
This commit adds a directory writer to libsquashfs that wrapps a meta data writer and provides a higher-level interface for writing directory entries. Under the hood it enforces the rules that squashfs insists upon. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
