From 2f9f48edddadffa2ac39ed7291f92be7be3b0fb5 Mon Sep 17 00:00:00 2001 From: Chantry Xavier Date: Sun, 9 Mar 2008 12:56:00 +0100 Subject: src/pacman/pacman.c : split cleanup function. This function was used in two different ways : - as a signal handler : the argument was the signal number - called manually for freeing the resources : the argument was the return value So the first part is now handler(int), and the second cleanup(int). Ref: http://www.archlinux.org/pipermail/pacman-dev/2008-March/011388.html Remaining problems : - the return values are messy. for example, 2 can mean both that it was interrupted (SIGINT == 2), or that --help or -V was used (returned by parseargs). - apparently signal is not portable and sigaction should be used instead Signed-off-by: Chantry Xavier --- src/pacman/pacman.c | 43 +++++++++++++++++++++++++------------------ 1 file changed, 25 insertions(+), 18 deletions(-) (limited to 'src') diff --git a/src/pacman/pacman.c b/src/pacman/pacman.c index d6997689..f46b71c1 100644 --- a/src/pacman/pacman.c +++ b/src/pacman/pacman.c @@ -188,11 +188,31 @@ static void setuseragent(void) setenv("HTTP_USER_AGENT", agent, 0); } +/** Free the resources. + * + * @param ret the return value + */ +static void cleanup(int ret) { + /* free alpm library resources */ + if(alpm_release() == -1) { + pm_printf(PM_LOG_ERROR, alpm_strerrorlast()); + } + + /* free memory */ + FREELIST(pm_targets); + if(config) { + config_free(config); + config = NULL; + } + + exit(ret); +} + /** Catches thrown signals.
