From 794bc489206ab19a6f819f2fdf477fbcf8109d23 Mon Sep 17 00:00:00 2001 From: Matthew Barnes Date: Thu, 14 Jul 2011 13:50:30 -0400 Subject: SpamAssassin: Try harder to kill spamd on exit. References to EMailSession are leaking like crazy, so the module's finalize() method never gets called, and we never kill our spamd. Until I can track down all the reference leaks, kill the spamd process in response to a "EShell::prepare-for-quit" signal instead of from the module's finalize() method. (Maybe that's a better long-term solution anyway?) --- modules/spamassassin/evolution-spamassassin.c | 91 ++++++++++++++++----------- 1 file changed, 53 insertions(+), 38 deletions(-) (limited to 'modules/spamassassin') diff --git a/modules/spamassassin/evolution-spamassassin.c b/modules/spamassassin/evolution-spamassassin.c index 1fcd369592..10cb3083a6 100644 --- a/modules/spamassassin/evolution-spamassassin.c +++ b/modules/spamassassin/evolution-spamassassin.c @@ -23,6 +23,7 @@ #include +#include #include #include #include @@ -512,6 +513,49 @@ spam_assassin_test_spamd_running (ESpamAssassin *extension, return (exit_code == 0); } +static void +spam_assassin_kill_our_own_daemon (ESpamAssassin *extension) +{ + gint pid; + gchar *contents = NULL; + GError *error = NULL; + + g_mutex_lock (extension->socket_path_mutex); + + g_free (extension->socket_path); + extension->socket_path = NULL; + + g_mutex_unlock (extension->socket_path_mutex); + + if (extension->pid_file == NULL) + return; + + g_file_get_contents (extension->pid_file, &contents, NULL, &error); + + if (error != NULL) { + g_warn_if_fail (contents == NULL); + g_warning ("%s", error->message); + g_error_free (error); + return; + } + + g_return_if_fail (contents != NULL); + + pid = atoi (contents); + g_free (contents); + + if (pid > 0 && kill (pid, SIGTERM) == 0) + waitpid (pid, NULL, 0); +} + +static void +spam_assassin_prepare_for_quit (EShell *shell, + EActivity *activity, + ESpamAssassin *extension) +{ + spam_assassin_kill_our_own_daemon (extension); +} + static gboolean spam_assassin_start_our_own_daemon (ESpamAssassin *extension) { @@ -571,6 +615,15 @@ spam_assassin_start_our_own_daemon (ESpamAssassin *extension) g_free (extension->socket_path); extension->socket_path = socket_path; socket_path = NULL; + + /* XXX EMailSession is too prone to reference leaks to leave + * this for our finalize() method.
