Hello, Sorry for contacting you directly.
I'm trying to port you patch (grep-2.5.1-egf-speedup.patch) to Debian. This patch triggered an issue when an empty pattern is used with the -Fw options. (see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=329876) I tried the Fedora grep-2.5.1-48.2 binary, which suffers from the same issue (on a Debian system, with a Debian libc and libpcre): echo foobar | grep -Fw "" hangs (this could appear with the -Fwf options when the patterns file contains an empty line). Changing the 'while (1)' loop to a 'while (len)' loop in search.c fix this issue. However, I don't know if this is correct or optimal (I don't know what should happen if we enter the loop with len>0 and len is then decreased to 0; Maybe this should also be catched earlier). Does it seems correct to you ? Sorry I could not check if a Redhat system suffers from this (that's the reson why I do not use the BTS) and thanks a lot for the impressive speed-up of grep on an UTF-8 environment, -- Nekral -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
