This Week in OpenNMS: Season 1.6, Episode 27: Databases, iPhones, and Releases, Oh My!

It's time for This Week in OpenNMS. This week we worked on the iPhone
app some more, went to OSCON, and prepped for new releases.


Project Updates
---------------

- Stable: Current Release is 1.6.5

1.6.5 is the current stable release, released May 16th.  It fixes a
number of bugs, and adds a few features.  For a full list, see the
bugzilla 1.6.5 milestone.  This is a non-critical but recommended
upgrade for anyone on OpenNMS versions older than 1.6.5.

- Unstable: Current Release is 1.7.5

1.7.5 is the current unstable release, tagged July 13th.  Since 1.7.4,
there have been a ton of bugfixes, as well as updates to thresholding,
RANCID, upgrades, maps, provisiond, and other juicy stuff.  A 1.7.x
overview is available in the release notes on the site.

- Stable: Database Connection Cleanups

Although we're trying to transition to Hibernate, we have plenty of JDBC
code left.  A customer ran into an issue that appeared to be related to
database connections not being cleaned up properly.  I created a utility
that can track the various connections, and cleaned up a bunch of our
JDBC-based code to use it.

- Stable: PostgreSQL Dependency Updates

For a while now, we've been careful to keep OpenNMS from interacting
with PostgreSQL versions that we aren't sure work, since some of our
JDBC calls can be pretty complex.  This week I spent some time
evaluating PostgreSQL 8.4.  The good news is, I've bumped the allowed
PostgreSQL versions up to 8.4.  The bad news is, 8.4.0 has a bug in the
new subselect optimizer that causes a number of queries including our
category filtering to fail, so you won't be able to take advantage of
the higher version limit until 8.4.1 is out.

I reported the bug upstream, and it should be fixed in PostgreSQL 8.4.1
when it is released.

- Stable: 1.6.6 Preparation

I started doing some prep work for a 1.6.6 release (validating bugs,
merging them to the release branch, etc.)  The goal was to release 1.6.6
and 1.7.6 this week, but I think I'm going to have to push 1.6.6 to next
week instead of trying to release them simultaneously.  We have a much
more rigorous process for what gets into the 1.6 release branch than
into unstable releases, and they need more scrutiny.

- Unstable: iPhone App Development

I've been working more on the iPhone app.  There are really only 2
things left to do: add the alarm detail page (which will hopefully
include acknowledging/escalating alarms), and finish wiring up the node
search to the node detail page.

Again, if there are any features you'd look for in the iPhone client,
please let me know. Obvious one is accessing graphs, but I haven't
figured out how much work that will be yet. ;)

- Unstable: Laszlo UI

Matt Raykowski spent a little time updating the Laszlo branch to current
trunk.

- Unstable: Inventory Updates

Antonio has been doing some bugfixes and work cleaning up some of the
inventory reports.

- Unstable: Thresholding Fixes

Alejandro fixed a number of thresholding issues including handling rates
properly.

- Unstable: SMS Pinger/Request-Response API

In the process of working on the SMS ping feature, Matt did some
refactoring to create a nice generic API for implementing code that
needs to track round-trips that can be used for a lot of applications
(ping, mail transport monitor, etc.)

- Unstable: RANCID Updates

Rocco put out a new version of the RANCID APIs.

- Unstable: REST APIs

I did some updates to the REST APIs to clean up generated XML, and also
to allow choosing whether to match "any" or "all" criteria passed on the
URL.

- Unstable: Bufixes

We've been doing plenty of other bugfixing in preparation for the new
release(s).  Donald fixed a high-profile one that's been bugging people
who use inferior browsers for a while (grin): bug #3233: Resource Graphs
don't work in IE.
