By using suffix sorting (specifically, Larsson and Sadakane's +qsufsort) and taking advantage of how executable files change, bsdiff +routinely produces binary patches 50-80% smaller than those produced by +Xdelta, and 15% smaller than those produced by .RTPatch (a $2750/seat +commercial patch tool). + +If n is the size of the old file and m is the size of the new file, bsdiff +runs in O((n+m) log n) time; on a 200MHz Pentium Pro, building a binary +patch for a 4MB file takes about 90 seconds. bspatch runs in O(n+m) time; +on the same machine, applying that patch takes about two seconds. diff --git a/misc/bsdiff/Makefile b/misc/bsdiff/Makefile new file mode 100644 index 00000000000..55879ab6a01 --- /dev/null +++ b/misc/bsdiff/Makefile @@ -0,0 +1,19 @@ +# $NetBSD: Makefile,v 1.1.1.1 2003/12/30 17:34:45 cjep Exp $ +# + +DISTNAME= bsdiff-4.1 +CATEGORIES= misc +MASTER_SITES= http://www.daemonology.net/bsdiff/ + +MAINTAINER= cjep@NetBSD.org +HOMEPAGE= http://www.daemonology.net/bsdiff/ +COMMENT= Size efficient binary diff and patch tools + +USE_BUILDLINK2= yes + +.if !exists(/usr/bin/bzip2) +MAKE_ENV+= BZIP2=${LOCALBASE}/bin/bzip2 +.endif + +.include "../../archivers/bzip2/buildlink2.mk" +.include "../../mk/bsd.pkg.mk" diff --git a/misc/bsdiff/PLIST b/misc/bsdiff/PLIST new file mode 100644 index 00000000000..4f3b2e7d7fc --- /dev/null +++ b/misc/bsdiff/PLIST @@ -0,0 +1,5 @@ +@comment $NetBSD: PLIST,v 1.1.1.1 2003/12/30 17:34:45 cjep Exp $ +bin/bsdiff +bin/bspatch +man/man1/bsdiff.1 +man/man1/bspatch.1 diff --git a/misc/bsdiff/distinfo b/misc/bsdiff/distinfo new file mode 100644 index 00000000000..93405ea40fb --- /dev/null +++ b/misc/bsdiff/distinfo @@ -0,0 +1,4 @@ +$NetBSD: distinfo,v 1.1.1.1 2003/12/30 17:34:45 cjep Exp $ + +SHA1 (bsdiff-4.1.tar.gz) = 0c24b121916704069f23199da0689b3e49b77796 +Size (bsdiff-4.1.tar.gz) = 7721 bytes |
