DMon 0.4.2 “Three Wise Men” released
7 January 2012
Don’t expect lots of surprises this time, but an otherwise smooth
maintenance release that includes a couple of minor niceties. Changes
since version 0.4.1 mostly affected the logging tools (
Logging tools now may accept input from arbitrary file descriptors, using the
--input-fdcommand line option. This enables to do some nice redirection tricks from shell scripts and other programs which use them.
Logging tools now support adding an arbitrary string in front of logged lines using the
--prefixoption. For example, this allows to send the output of several commands to a FIFO, and when reading from it it would be possible to know which command originated the message in the resulting output:
mkfifo logpipe dmon cat logpipe -- dlog -t /var/log/combined dmon command1 -- dlog -p command1: logpipe dmon command2 -- dlog -p command2: logpipe dmon command3 -- dlog -p command3: logpipe
Logging tools now handle the
HUPsignals. When signalled, they will flush buffers to disk, and in the case of
drlogcheck if log rotation is needed; for
TERMthe processes will also shut down gracefully.
The manual pages now also include the long variant of command line options.
A number of small improvements: better error messages, removal of some unused code, updated to a slightly newer version of
libwheel, better and more consistent command line parsing, silent Make rules…
Make sure you grab the tarball while it is still fresh, and do not forget that a package for Arch Linux is available in the AUR.
Update, Jan 30th: Packages for DMon 0.4.2 are now also available at
the Igalia APT respoitory, for
