File libcdio-0.94-leak-07.patch of Package libcdio.7811
Backport. From 73800fc0cd81a735764f79b7f3f957d8a71eb02c Mon Sep 17 00:00:00 2001 From: "R. Bernstein" <rocky@gnu.org> Date: Tue, 28 Nov 2017 23:39:14 -0500 Subject: [PATCH 7/20] WIP: deal with memory leaks from cdio_lists TODO: * create function for dirlist free; is: _cdio_list_free (dirlist, true, free); * create function for statbuf free; is: _cdio_list_free (entlist, true, (CdioDataFree_t) iso9660_stat_free); * Add targets to run valgrind to look for memory leaks * Fix remaining memory leaks --- configure.ac | 2 +- example/extract.c | 4 +- example/isofuzzy.c | 26 +++--- example/isolist.c | 29 +++---- example/udf1.c | 2 +- example/udffile.c | 44 +++++----- include/cdio++/iso9660.hpp | 174 ++++++++++++++++++------------------- include/cdio/ds.h | 5 +- include/cdio/types.h | 4 + lib/cdio++/iso9660.cpp | 106 +++++++++++----------- lib/driver/_cdio_stream.c | 2 +- lib/driver/ds.c | 11 +-- lib/driver/image/nrg.c | 5 +- lib/iso9660/iso9660_fs.c | 29 ++++--- src/cd-info.c | 8 +- src/iso-info.c | 28 +++--- test/testisocd2.c | 34 +++++--- 17 files changed, 263 insertions(+), 250 deletions(-) Index: libcdio-0.94/configure.ac =================================================================== --- libcdio-0.94.orig/configure.ac +++ libcdio-0.94/configure.ac @@ -190,7 +190,7 @@ AC_DEFINE(LIBCDIO_CONFIG_H, 1, dnl headers AC_HEADER_STDC -AC_CHECK_HEADERS(errno.h fcntl.h glob.h limits.h pwd.h stdbool.h) +AC_CHECK_HEADERS(alloca.h errno.h fcntl.h glob.h limits.h pwd.h stdbool.h) AC_CHECK_HEADERS(stdarg.h stdbool.h stdio.h sys/cdio.h sys/param.h \ sys/time.h sys/timeb.h sys/utsname.h) Index: libcdio-0.94/example/extract.c =================================================================== --- libcdio-0.94.orig/example/extract.c +++ libcdio-0.94/example/extract.c @@ -1,6 +1,6 @@ /* Copyright (C) 2012 Pete Batard <pete@akeo.ie> - Based on samples copyright (c) 2003-2011 Rocky Bernstein <rocky@gnu.org> + Based on samples copyright (c) 2003-2011, 2017 Rocky Bernstein <rocky@gnu.org> This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by @@ -236,7 +236,7 @@ static int iso_extract_files(iso9660_t* out: if (fd != NULL) fclose(fd);
