From b82ba953905f806ce4e5553c1536579080b7352e Mon Sep 17 00:00:00 2001 From: Ingo Schwarze Date: Sun, 16 Jan 2011 19:27:26 +0000 Subject: Some improvements to error handling from kristaps@: * Make out-of-context .fi invocations not cause an error, but just a warning. * Downgrade -man message about ignored empty paragraph to MANDOC_IGNPAR. * Avoid syntax tree corruption when removing empty block macros. Triggered by some reports from brad@. --- usr.bin/mandoc/man_macro.c | 18 +++++++++++++----- 1 file changed, 13 insertions(+), 5 deletions(-) (limited to 'usr.bin/mandoc/man_macro.c') diff --git a/usr.bin/mandoc/man_macro.c b/usr.bin/mandoc/man_macro.c index a30b585b91a..413cbbd56ee 100644 --- a/usr.bin/mandoc/man_macro.c +++ b/usr.bin/mandoc/man_macro.c @@ -1,4 +1,4 @@ -/* $Id: man_macro.c,v 1.26 2011/01/04 22:28:17 schwarze Exp $ */ +/* $Id: man_macro.c,v 1.27 2011/01/16 19:27:25 schwarze Exp $ */ /* * Copyright (c) 2008, 2009, 2010 Kristaps Dzonsons * @@ -103,19 +103,27 @@ rew_warn(struct man *m, struct man_node *n, enum mandocerr er) * will be used if an explicit block scope is being closed out. */ int -man_unscope(struct man *m, const struct man_node *n, +man_unscope(struct man *m, const struct man_node *to, enum mandocerr er) { + struct man_node *n; - assert(n); + assert(to); /* LINTED */ - while (m->last != n) { + while (m->last != to) { + /* + * Save the parent here, because we may delete the + * m->last node in the post-validation phase and reset + * it to m->last->parent, causing a step in the closing + * out to be lost. + */ + n = m->last->parent; if ( ! rew_warn(m, m->last, er)) return(0); if ( ! man_valid_post(m)) return(0); - m->last = m->last->parent; + m->last = n; assert(m->last); } -- cgit v1.2.3
