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>
2019-08-04Improve file unpacking orderDavid Oberhollenzer
This commit moves the file unpacking order & job scheduling to a libfstree function. The ordering is improved by making sure fragment blocks are not extracted more than once and files with data blocks are extracted in order. This way, serial unpacking of a 2GiB Debian live image could be reduced from ~5' on my test machine to ~3.5', whereas parallel unpacking stays roughly the same (~3' for -j 4).

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.
