From 77313cd0d13ed3682f25c745f71f648292b28215 Mon Sep 17 00:00:00 2001 From: "kay.sievers@vrfy.org" Date: Sat, 26 Feb 2005 02:52:04 +0100 Subject: [PATCH] [PATCH] namedev: skip backslashes only if followed by newline Fix from: Hannes Reinecke namedev_parse is a bit overzealous when in comes to handling backspaces; it always eats up backspaces regardless of anything beyond that. This means it is impossible to enter '\t' in a rule. Quite a bit of fun when you're trying to write regexps. --- namedev_parse.c | 2 +- test/udev-test.pl | 9 +++++++++ 2 files changed, 10 insertions(+), 1 deletion(-) diff --git a/namedev_parse.c b/namedev_parse.c index 7cd676c3..02d8a652 100644 --- a/namedev_parse.c +++ b/namedev_parse.c @@ -153,7 +153,7 @@ static int namedev_parse(const char *filename, void *data) /* skip backslash and newline from multi line rules */ for (i = j = 0; i < count; i++) { - if (bufline[i] == '\\' || bufline[i] == '\n') + if (bufline[i] == '\\' && bufline[i+1] == '\n') continue; line[j++] = bufline[i]; diff --git a/test/udev-test.pl b/test/udev-test.pl index fe7b9326..f442b162 100644 --- a/test/udev-test.pl +++ b/test/udev-test.pl @@ -192,6 +192,15 @@ EOF KERNEL="ttyUSB0", \\ NAME="visor" +EOF + }, + { + desc => "preserve backslashes, if they are not for a newline", + subsys => "tty", + devpath => "/class/tty/ttyUSB0", + exp_name => "aaa", + conf => <
