From b9f0ea6f0e16f2314a2bdd56365205e7a3c31aa1 Mon Sep 17 00:00:00 2001 From: Evan Prodromou Date: Wed, 27 Aug 2008 16:54:07 -0400 Subject: [PATCH] break up monolithic xmppdaemon into multiple queue handlers Eventually, the poor xmppdaemon has become overloaded with extra tasks. So, I've broken it up. Now, we have 5 background scripts, and more coming: * xmppdaemon.php - handles incoming XMPP messages only. * xmppqueuehandler.php - sends notices from the queue out through XMPP. * smsqueuehandler.php - sends notices from the queue out over SMS * ombqueuehandler.php - sends notices from the queue out over OMB * xmppconfirmhandler.php - sends confirmation requests out over XMPP. This is in addition to maildaemon.php, which takes incoming messages. None of these are "true" daemons -- they don't daemonize themselves automatically. Use nohup or another tool to background them. monit can also be useful to keep them running. At some point, these might become fork()'ing daemons, able to handle more than one notice at a time. For now, I'm just running multiple instances, hoping they don't interfere. darcs-hash:20080827205407-84dde-97884a12f5f4e54c93bc785bd280683d1ee7e749.gz --- classes/Queue_item.php | 30 +++++ lib/jabber.php | 52 ++++++--- lib/queuehandler.php | 105 +++++++++++++++++ lib/util.php | 29 ++--- scripts/ombqueuehandler.php | 70 ++++++++++++ scripts/smsqueuehandler.php | 63 ++++++++++ scripts/xmppconfirmhandler.php | 135 ++++++++++++++++++++++ scripts/xmppdaemon.php | 202 +-------------------------------- scripts/xmppqueuehandler.php | 65 +++++++++++ 9 files changed, 522 insertions(+), 229 deletions(-) create mode 100644 lib/queuehandler.php create mode 100755 scripts/ombqueuehandler.php create mode 100755 scripts/smsqueuehandler.php create mode 100755 scripts/xmppconfirmhandler.php create mode 100755 scripts/xmppqueuehandler.php diff --git a/classes/Queue_item.php b/classes/Queue_item.php index a953e141b8..2ae78d9f64 100644 --- a/classes/Queue_item.php +++ b/classes/Queue_item.php @@ -22,4 +22,34 @@ class Queue_item extends DB_DataObject ###END_AUTOCODE function sequenceKey() { return array(false, false); } + + static function top($transport) { + + $qi = new Queue_item(); + $qi->transport = $transport; + $qi->orderBy('created'); + $qi->whereAdd('claimed is NULL'); + + $qi->limit(1); + + $cnt = $qi->find(TRUE); + + if ($cnt) { + # XXX: potential race condition + # can we force it to only update if claimed is still NULL + # (or old)? + $this->log(LOG_INFO, 'claiming queue item = ' . $qi->notice_id); + $orig = clone($qi); + $qi->claimed = common_sql_now(); + $result = $qi->update($orig); + if ($result) { + $this->log(LOG_INFO, 'claim succeeded.'); + return $qi; + } else { + $this->log(LOG_INFO, 'claim failed.'); + } + } + $qi = NULL; + return NULL; + } } diff --git a/lib/jabber.php b/lib/jabber.php index 1202aa3222..e2f7ca3c82 100644 --- a/lib/jabber.php +++ b/lib/jabber.php @@ -26,23 +26,45 @@ require_once('XMPPHP/XMPP.php'); class Laconica_XMPP extends XMPPHP_XMPP { function messageplus($to, $body, $type = 'chat', $subject = null, $payload = null) { - $to = htmlspecialchars($to); - $body = htmlspecialchars($body); - $subject = htmlspecialchars($subject); - - $jid = jabber_daemon_address(); - - $out = ""; - if($subject) $out .= "$subject"; - $out .= "$body"; - if($payload) $out .= $payload; - $out .= ""; - + $to = htmlspecialchars($to); + $body = htmlspecialchars($body); + $subject = htmlspecialchars($subject); + + $jid = jabber_daemon_address(); + + $out = ""; + if($subject) $out .= "$subject"; + $out .= "$body"; + if($payload) $out .= $payload; + $out .= ""; + $cnt = strlen($out); common_log(LOG_DEBUG, "Sending $cnt chars to $to"); - $this->send($out); + $this->send($out); common_log(LOG_DEBUG, 'Done.'); } + + public function presence($status = null, $show = 'available', $to = null, $type='available', $priority=NULL) { + if($type == 'available') $type = ''; + $to = htmlspecialchars($to); + $status = htmlspecialchars($status); + if($show == 'unavailable') $type = 'unavailable'; + + $out = "send($out); + } } function jabber_valid_base_jid($jid) { @@ -64,7 +86,7 @@ function jabber_daemon_address() { return common_config('xmpp', 'user') .
