Colin pointed out on IRC that there's a caveat to this: bspatch allocates enough memory to store the entire original file, and the entire modified file, and performs all of the patching operations in memory. This might fail on extremely memory-constrained systems, with freebsd-update then falling back to fetching the full file. However, this is an implementation detail, not a fundamental aspect of the bsdiff/bspatch format. I believe it should be possible for bspatch to operate in a (perhaps slower) reduced memory mode, if it turns out this is a significant issue in practice. _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
