QPID-5942: qpid HA cluster may end-up in joining state after HA primary is killed

2014-07-31T13:55:11+00:00

There are two issues here, both related to the fact that rgmanager sees qpidd
and qpidd-primary as two separate services.

1. The service start/stop scripts can be called concurrently. This can lead to
running a qpidd process who's pid is not in the pidfile. rgmanager cannot
detect or kill this qpidd and cannot start another qpidd because of the lock
on the qpidd data directory.

2. rgmanager sees a primary failure as two failures: qpidd and qpidd-primary,
and will then try to stop and start both services. The order of these actions
is not defined and can lead to rgmanager killing a service it has just
started.

This patch makes two major changes to the init scripts:

1. Uses flock to lock the sensitive stop/start part of the scripts to ensure
they are not executed concurrently.

2. On "stop" the scripts check if a running qpidd is primary or not. "qpidd stop"
is a no-op if the running broker is primary, "qpidd-primary stop" is a no op
if it is not. This ensures that a broker will be stopped by the same stream
of service actions that started it.

Minor changes in this patch:
- better logging of broker start-up and shut-down sequence.
- qpid-ha heartbeat use half of timeout option.
- add missing timeouts in qpid-ha.

Notes:

This changes the behavior of 'clusvcadm -d ' on the primary node.
Previously this would have stopped the qpidd service on that node, killed the
qpidd process and relocated the primary service. Now this will stop the qpidd
service (as far as rgmanager is concerned) but will not kill qpidd or relocate
the primary service. When the primary is relocated the qpidd service wil not be
able to re-start on that node until it is re-enabled with 'clusvcadm -e'.

QPID-4745: Alternative port allocation for tests, instead of 'qpidd --port=0'

2013-06-18T21:09:19+00:00

qpidd-p0 script binds a new port to a socket using bind(0), and then
execs qpidd using the --socket-fd option to pass the socket to qpidd.

It is intended to replace
  /path/to/qpidd --port 0 
with
  qpidd-p0 /path/to/qpidd 

Most tests do not yet use qpidd-p0, they will be updated in a future commit.

Changes:
- Added qpidd-p0
- Fixed qpidd port printing logic: print port only if --port=0, regardless of --transport.

QPID-4758: Extend the qpidd --wait option to work at shutdown

2013-04-24T14:40:17+00:00

Patch from Ernie Allen and Pavel Moravec.
Note: This patch is for the posix platform broker; The windows broker does not use a --wait option and is unaffected by this patch.

QPID-3689: Fix previous change of command line option handling

2013-04-18T17:18:11+00:00

Now introduced new command line option type that is a pure command
line switch which can take no boolean argument.

QPID-4449 - Reverted much of the original change and re-implemented the fix in a simpler way.

2012-11-30T19:17:28+00:00

The build-define _IN_QPID_BROKER is now used for modules built in the broker.  The shared-pointer
changes are conditionally compiled only for in-broker cases.

QPID-3500 C++ qpidd broker --help should work despite parse errors

2012-09-20T13:48:40+00:00

This patch finds and processes --version before anything else.
Then it finds --help before fully parsing command line options. 
In the event of a parse error, help usage may be shown as requested.

NO-JIRA: Reduce message for missing lock file from critical to notice.

2012-05-14T19:45:04+00:00

If qpidd -q can't find the lock file, it used to issue a critical error message.
This is to harsh, not finding the lock file usually just means the broker isn't running.
Demoted to a notice message.
