procps-ng 3.3.16

procps-ng version 3.3.16 was released today. Besides some documentation and library updates, there were a few incremental changes.

Zombie Hunting with pgrep

Ever wanted to find zombies? Perhaps processes with other states? pgrep has a shiny new runstate flag to help you which will match process against the runstate. I’m curious to see the use-cases for this flag; it certainly will get used (e.g. find my zombies) but as some processes bounce in and out of states (think Run to Sleep and back) it might add some confusion.

Snice plays nice with PIDs

Speaking of ancient corpses, snice was not matching against PIDs. The best use for snice is to not use it (as the man page says) but some people do and some people noticed it never matched against PIDs.
The issue was reading the process state up to 128 bytes, but process state lines are always longer than 128 bytes so a bounds check failed and it skipped that PID (and every other PID too).

Top Enhancements

Top got a bunch of love again in this release. If you ever wanted your processes to be shown in fuchsia? Perhaps goldenrod? With some earlier versions of top, you could by directly editing the toprc file but now everyone can have more than the standard 8 colours!

If you use the other filters parameter for some fancy process filtering in top, it now will save that configuration.

Collapsed children (process names are weird) get some help. If you are in tree view, you can collapse or fold the children processes under the parent. Their CPU is also added to the parent so there are no “missing” CPU ticks.

For people who use the One True Editor (which is, of course, VIM) you can use the vim navigation keys to move through the process list.

Where to find it?

You’ll find the latest version of procps either at our git repository or download a tarball.

WordPress 4.9.1

After a much longer than expected break due to moving and the resulting lack of Internet, plus WordPress releasing a package with a non-free file, the Debian package for WordPress 4.9.1 has been uploaded!

WordPress 4.9 has a number of improvements, especially around the customiser components so that looked pretty slick. The editor for the customiser now has a series of linters what will warn if you write something bad, which is a very good thing! Unfortunately the Javascript linter is jshint which uses a non-free license which that team is attempting to fix.  I have also reported the problem to WordPress upstream to have a look at.

While this was all going on, there were 4 security issues found in WordPress which resulted in the 4.9.1 release.

Finally I got the time to look into the jshint problem and Internet to actually download the upstream files and upload the Debian packages. So version 4.9.1-1 of the packages have now been uploaded and should be in the mirrors soon.  I’ll start looking at the 4.9.1 patches to see what is relevant for Stretch and Jessie.

jffnms 0.9.4

JFFNMS version 0.9.4 was released today, this version fixes some bugs that have recently appeared in previous versions.

Alarmed Interfaces and Events
Alarmed Interfaces and Events

The triggers rules editor had a problem where some of the rules clicked off the triggers would not appear or could not be edited correctly.

Most of the Admin screens have the ability to sort the rows. This, unfortunately, didn’t sort but the functionality has been restored.

Most users are probably unaware of this, but the database schema is first created for MySQL and is then converted for PostgreSQL. The conversi0n process is far from ideal and hasn’t worked until this release. More testing is required for PostgreSQL support but it should be a lot better.

JFFNMS – 3rd RC lucky?

I’ve just uploaded to sourceforge the third and hopefully last RC for JFFNMS network management system version 0.9.0  The reason for the delay was easter as well as I wanted to test the engines for a long while to make sure I was not getting any orphan children or items. Previous versions had processes that never died or if they died the parent didn’t realise and didn’t handle the item, permanently making the item “out for work”.

PHP5 has much better job and process handling and the new version takes advantage of this handling.  It’s run well on my on test setup for a week or two. You can find the RC code or just the older releases at https://sourceforge.net/projects/jffnms/files/
