From 089315bcaa29aca8ada95ff0f2bdf36aac16a00e Mon Sep 17 00:00:00 2001 From: Alexander Butenko Date: Sun, 10 Jan 2010 22:52:06 +0100 Subject: [PATCH] Speedup adblock with blacklists and reorganize unit tests 1. Blacklist for pattern matching. 1 regexp has more than 1 signature. If the 1st match failed, there is no need to match with the same regex a second time if the signature matched. This gives us 20% speedup. 2. Cleanup for performance tests. 3. Tests reorganized. now we are checking pattern validation plus performance timing. Simlifies testing. 4. Bump version to 0.5. The next patch will add option matching so we will bump it to 1.0 once it is tested. --- extensions/adblock.c | 64 +++++++++++++++----------------------------- 1 file changed, 22 insertions(+), 42 deletions(-) diff --git a/extensions/adblock.c b/extensions/adblock.c index 01757a60..26ec5378 100644 --- a/extensions/adblock.c +++ b/extensions/adblock.c @@ -589,6 +589,7 @@ adblock_is_matched_by_key (const gchar* opts, gchar* uri;
