2021-03-30Fix: don't throw an error if fsync() returns EINVALDavid Oberhollenzer
This indicates that sync isn't possible on the underlying file descriptor (e.g. a pipe), which currently causes sqfs2tar to err if the output isn't written directly to a file. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2021-03-20Fix: add missing include path to libfstream if using builtin zlibDavid Oberhollenzer

2020-09-29libfstream: Rework unix sparse file writingDavid Oberhollenzer
Instead of immediately seeking forward, record the sparse bytes "written" and then do the seek the next time we write data, or do an ftruncate if we do a sync. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-09-17Add a check whether libzstd supports stream compressionDavid Oberhollenzer
Streaming compression was added fairly recently to zstd (and then the API was changed a few times). Rather than rely on libzstd versioning macros, this commit adds an m4 script to test at configure time if the enums/functions we need are available by trying to compile a small sample.

2020-09-17Fix: add missing compiler/linker flagsDavid Oberhollenzer
If tar2sqfs and sqfs2tar want to use comperssion via libfstream, they need to link against the compressor libraries. Also, libfstream may need the apropriate cflags to access the headers on some platforms. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
