2019-09-27Cleanup: merge data.h into block.hDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-10API cleanup: eliminate boolean argumentsDavid Oberhollenzer
Replace them with flag fields which can be extended in the future without breaking the ABI. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
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.

2019-09-08Replace direct file I/O with abstraction layerDavid Oberhollenzer
This should make it easier to use libsquashfs with custom setups that embedd a squashfs image inside something else. Also, it should make it easier to port to non unix-like platforms. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
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.

2019-09-05Cleanup naming scheme of compressorDavid Oberhollenzer
Add sqfs_* prefix to compressor, move implementation prefix up front. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-05Cleanup: add sqfs_* prefix to meta writerDavid Oberhollenzer

2019-07-30Add propper copyright headers to all source filesDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-07-24Enable largefile supportMatt Turner
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.

2019-07-16cleanup: move error handling into write_retryDavid Oberhollenzer
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 <david.oberhollenzer@sigma-star.at>
2019-07-10Add a way to keep meta data blocks in memoryDavid Oberhollenzer
Instead of writing meta data blocks directly to disk, the writer can now alternatively keep the blocks in memory until explicitly told to write to disk. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-05-04Remove compressor internal buffersDavid Oberhollenzer
Pass in an external destination buffer + size and allow for propper bounds checking (especially when unpacking). Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
