From 2d14351d07ed74373585b7cf8b4146d5b5c91ccb Mon Sep 17 00:00:00 2001 From: Ingo Schwarze Date: Wed, 9 Sep 2020 17:01:10 +0000 Subject: Element next-line scopes can nest. Consequently, even when closing one element next-line scope, the MAN_ELINE flag must not yet be cleared if the parent macro is another element macro having next-line scope, or an assertion failure is caused if all this is wrapped in another macro that has block next-line scope, for example .TP. Bug found in an afl run performed by Jan Schreiber . --- regress/man/TP/broken.in | 9 ++++++--- regress/man/TP/broken.out_ascii | 4 ++-- regress/man/TP/broken.out_lint | 3 +++ regress/man/TP/macrotag.in | 18 +++++++++++++++--- regress/man/TP/macrotag.out_ascii | 10 ++++++++-- 5 files changed, 34 insertions(+), 10 deletions(-) (limited to 'regress/man/TP') diff --git a/regress/man/TP/broken.in b/regress/man/TP/broken.in index 686b5559..b0813432 100644 --- a/regress/man/TP/broken.in +++ b/regress/man/TP/broken.in @@ -1,7 +1,7 @@ -.\" $OpenBSD: broken.in,v 1.3 2017/07/04 14:53:24 schwarze Exp $ -.TH TP-BROKEN 1 "December 16, 2014" +.\" $OpenBSD: broken.in,v 1.4 2020/09/09 16:57:05 schwarze Exp $ +.TH TP-BROKEN 1 "September 9, 2020" .SH NAME -TP-broken \- broken tagged paragraph +TP-broken \- broken tagged paragraphs .SH DESCRIPTION regular text @@ -16,3 +16,6 @@ text head body +.TP +.B +.I diff --git a/regress/man/TP/broken.out_ascii b/regress/man/TP/broken.out_ascii index 68fab4f0..0e817a9c 100644 --- a/regress/man/TP/broken.out_ascii +++ b/regress/man/TP/broken.out_ascii @@ -3,7 +3,7 @@ TP-BROKEN(1) General Commands Manual TP-BROKEN(1) NNAAMMEE - TP-broken - broken tagged paragraph + TP-broken - broken tagged paragraphs DDEESSCCRRIIPPTTIIOONN regular text @@ -14,4 +14,4 @@ DDEESSCCRRIIPPTTIIOONN -OpenBSD December 16, 2014 TP-BROKEN(1) +OpenBSD September 9, 2020 TP-BROKEN(1) diff --git a/regress/man/TP/broken.out_lint b/regress/man/TP/broken.out_lint index 2539a622..a0b83e81 100644 --- a/regress/man/TP/broken.out_lint +++ b/regress/man/TP/broken.out_lint @@ -1,2 +1,5 @@ mandoc: broken.in:11:2: WARNING: line scope broken: RE breaks TP mandoc: broken.in:16:1: WARNING: skipping blank line in line scope +mandoc: broken.in:21:2: WARNING: line scope broken: EOF breaks I +mandoc: broken.in:20:2: WARNING: line scope broken: EOF breaks B +mandoc: broken.in:19:2: WARNING: line scope broken: EOF breaks TP diff --git a/regress/man/TP/macrotag.in b/regress/man/TP/macrotag.in index ec214f41..4f6d8029 100644 --- a/regress/man/TP/macrotag.in +++ b/regress/man/TP/macrotag.in @@ -1,7 +1,7 @@ -.\" $OpenBSD: macrotag.in,v 1.3 2017/07/04 14:53:24 schwarze Exp $ -.TH TP-MACROTAG 1 "September 20, 2011" +.\" $OpenBSD: macrotag.in,v 1.4 2020/09/09 16:57:05 schwarze Exp $ +.TH TP-MACROTAG 1 "September 9, 2020" .SH NAME -TP-macrotag \- macro in the head of a tagged paragraph +TP-macrotag \- macros in the head of tagged paragraphs .SH DESCRIPTION regular text @@ -9,6 +9,18 @@ text .B longindent indented text +.TP +.B +.I +next-line +indented +text +.TP +.B +.SM +bold small +indented +text .PP regular text diff --git a/regress/man/TP/macrotag.out_ascii b/regress/man/TP/macrotag.out_ascii index e466adcf..97b604a8 100644 --- a/regress/man/TP/macrotag.out_ascii +++ b/regress/man/TP/macrotag.out_ascii @@ -3,7 +3,7 @@ TP-MACROTAG(1) General Commands Manual TP-MACROTAG(1) NNAAMMEE - TP-macrotag - macro in the head of a tagged paragraph + TP-macrotag - macros in the head of tagged paragraphs DDEESSCCRRIIPPTTIIOONN regular text @@ -11,8 +11,14 @@ DDEESSCCRRIIPPTTIIOONN lloonnggiinnddeenntt indented text + _n_e_x_t_-_l_i_n_e + indented text + + bboolldd ssmmaallll + indented text + regular text -OpenBSD September 20, 2011 TP-MACROTAG(1) +OpenBSD September 9, 2020 TP-MACROTAG(1) -- cgit
