From 928a7c06dc830455c246e1ccb8fd980c882b1637 Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Sat, 18 Jun 2005 14:20:24 +0000 Subject: [PATCH] * Don't create patches for archives >= 150 MB because bsdiff can't handle it. It crashed on the 234 MB tetex archive. Probably we will never be able to handle archives of that size on 32-bit machines (because bsdiff does everything in memory requiring max(17*n,9*n+m)+O(1) bytes, so the address space simply isn't there). --- scripts/generate-patches.pl.in | 14 +++++++++++++- 1 file changed, 13 insertions(+), 1 deletion(-) diff --git a/scripts/generate-patches.pl.in b/scripts/generate-patches.pl.in index b27181da4..5dfacd896 100755 --- a/scripts/generate-patches.pl.in +++ b/scripts/generate-patches.pl.in @@ -277,13 +277,25 @@ foreach my $p (keys %dstOutPaths) { my $srcNarBz2 = getNarBz2 \%srcNarFiles, $closest; my $dstNarBz2 = getNarBz2 \%dstNarFiles, $p; - + + my $maxNarSize = 150 * 1024 * 1024; + system("@bunzip2@ < $srcNarBz2 > $tmpdir/A") == 0 or die "cannot unpack $srcNarBz2"; + if ((stat "$tmpdir/A")[7] >= $maxNarSize) { + print " skipping, source is too large\n"; + next; + } + system("@bunzip2@ < $dstNarBz2 > $tmpdir/B") == 0 or die "cannot unpack $dstNarBz2"; + if ((stat "$tmpdir/B")[7] >= $maxNarSize) { + print " skipping, destination is too large\n"; + next; + } + system("@libexecdir@/bsdiff $tmpdir/A $tmpdir/B $tmpdir/DIFF") == 0 or die "cannot compute binary diff";
