From bb1293d975294884a95b9cb298432c9cf9ecc995 Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Fri, 11 Dec 2009 00:23:18 +0100 Subject: Backport rred patches from my own sid branch to the 0.7.25 branch * rewrite and refactor rred method to be able to handle even big (>30 MB) patches (Closes: #554349) and hardening the method itself by using more constants and a return value which can't be misinterpreted as linenumber * Finally adope the patch from Morten Hustveit to be able to optional use mmaps and iovec to increase patch speed - but as this increase memory usage we can always fall back to the "old" method which doesn't depend on mmaps. --- methods/rred.cc | 648 ++++++++++++++++++++++++++++++++++++++++---------------- 1 file changed, 464 insertions(+), 184 deletions(-) (limited to 'methods') diff --git a/methods/rred.cc b/methods/rred.cc index 27d95bdde..262c78cab 100644 --- a/methods/rred.cc +++ b/methods/rred.cc @@ -1,202 +1,443 @@ +// Includes /*{{{*/ #include +#include #include #include #include #include #include +#include #include #include #include #include #include - -/* this method implements a patch functionality similar to "patch --ed" that is - * used by the "tiffany" incremental packages download stuff. it differs from - * "ed" insofar that it is way more restricted (and therefore secure). in the - * moment only the "c", "a" and "d" commands of ed are implemented (diff - * doesn't output any other). additionally the records must be reverse sorted - * by line number and may not overlap (diff *seems* to produce this kind of - * output). + /*}}}*/ +/** \brief RredMethod - ed-style incremential patch method {{{ + * + * This method implements a patch functionality similar to "patch --ed" that is + * used by the "tiffany" incremental packages download stuff.
