22# to assume all libraries will end up in lib. Replace any (sane) instances
23# where lib is named directly with $(get_libdir) if possible.

716# - bulk patch handling similar to epatch()'s
717# - automatic patch level detection like epatch()'s
718# - automatic patch uncompression like epatch()'s
719# - doesn't have the --dry-run overhead of epatch() - inspects patchfiles
720# manually instead
721# - once I decide it's production-ready, it'll be called from base_src_unpack
722# to handle $PATCHES to avoid defining src_unpack just to use xpatch
723
724# accepts zero or more parameters specifying patchfiles and/or patchdirs
725
726# known issues:
727# - only supports unified style patches (does anyone _really_ use anything
728# else?)
729# - because it doesn't use --dry-run there is a risk of it failing
730# to find the files to patch, ie detect the patchlevel, properly. It doesn't use
731# any of the backup heuristics that patch employs to discover a filename.
732# however, this isn't dangerous because if it works for the developer who's
733# writing the ebuild, it'll always work for the users, and if it doesn't,
734# then we'll fix it :-)

916# the size of the off_t type (in bytes) on the machine that built the pdv
917# archive. one way to determine this is by running the following commands:
918# strings <pdv archive> | grep lseek
919# strace -elseek <pdv archive>
920# basically look for the first lseek command (we do the strings/grep because
921# sometimes the function call is _llseek or something) and steal the 2nd
922# parameter. here is an example:
923# root@vapier 0 pdv_unpack # strings hldsupdatetool.bin | grep lseek
924# lseek
925# root@vapier 0 pdv_unpack # strace -elseek ./hldsupdatetool.bin
