2019-09-20Move "optimize unpack order" to from fstree to rdsquashfsDavid Oberhollenzer
Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-09-20Remove parallel unpackingDavid Oberhollenzer
Parallel unpacking didn't really improve the speed that much. Actually sorting the files for optimized unpack order improved speed much more than the parallel unpacker. Furthermore, the fork based parallel unpacker was actually pretty messy to begin with. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-07-25Add assertion around canonicalize_name in rdsquashfsDavid Oberhollenzer
The names generated by fstree are always in the correct format, but this is still needed for the sake of documentation and to guide static analysis tools. Should canonicalize_name fail on an fstree generated name, something is serverly broken. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
2019-07-25Terminate the unpacker child processes if the main process exitsDavid Oberhollenzer
Should the main process exit (e.g. the user presses CTRL+C) or explcitily sends it a signal, the desired behaviour is for the children to stop unpacking and exit. This commit adds a line to configure the kernel to send SIGKILL to the children if their parent dies. The same option also exists on various BSDs (not all of them) but with a different name which has to be checked for and adjusted should the program be required to run on one of those.

2019-07-25cleanup: remove some redundant header inclusionsDavid Oberhollenzer
The utility programs pretty much all have the same structure of including one central header per C file that includes all required library headers, so we can simply include config.h which we need for large file support from there and remove it from the C files. 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.

2019-05-05rdsquashfs: reorder unpack flags, add flag to produce listingDavid Oberhollenzer
The listing command has been used successfully to do the following: - generate a prestine file system using gensquashfs - repeate multiple times: - generate a listing from the file system - unpack only the regular files from the file system - generate a new file system from the listing - run `diff` on the old and new filesystem and admire that they are identical - replace the old file system with the new one, since they are identical Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-05-04rdsquashfs: malloc extraction buffers ahead of timeDavid Oberhollenzer
Instead of malloc/freeing the buffers for every file, allocate them once, ahead of time. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-05-04Rename tools to not collide with squashfs-toolsDavid Oberhollenzer
This commit changes the names of the tools to gensquashfs and rdsquashfs so they don't collide with the names used by the squashfs-tools package and the two can be installed side by side. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
