2020-04-02Add a libcompat implementation for getopt_longDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-04-02Add a libcompat implementation of getoptDavid Oberhollenzer
Limited to the subset actually needed. Vaguely inspired by the NetBSD libc implementation. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-04-02Import the remaining utility files into VisualStudio projectDavid Oberhollenzer
- The libcommon print verion function requires the PACKAGE_NAME and PACKAGE_VERSION defines. Those are added manually to the msvc stub of config.h. - Also, libcommon cannot directly include getopt.h - libfstree needs to change the return type for getline Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2020-04-01Add preliminary VisualStudio supportDavid Oberhollenzer
- Mostly workarounds/clutches in compat.h - Change getline return type to int - Replace C99 style flexible array with alloca - Add all the MSVC solution/project crap Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-11-25Cleanup: move overflow safe alloc code into libsquashfsDavid Oberhollenzer
There were only a hand full of instances outside libsquashfs that used the alloc code. In most cases, the thing allocated hat its size derived from something already in memory anyway, so it is safe to assume its size fits into a size_t. At the same time, the opencoded Windows path conversion functions are all unified into a single helper function. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-11-22Add fchownat/fchmodat mockups to libcompat for WindowsDavid Oberhollenzer
Not pretty, but definitely prettier than #ifdef hell. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-11-22Cleanup: move all the compatibillity fluff to a dedicated "libcompat"David Oberhollenzer
