A useful little program, but... this might be OT, but let me point out that the name collides with Debian's debhelper (also invoked as dh) Until now, I was unaware of debhelper. It's hard to find a short name not already taken. I decided that dh was a good representation of its function, and I wanted a two character name that's easy to use with minimal keystrokes. I apologize to debhelper users, but I have no desire to change the name of daemon helper now. dh is its name; a natural companion to sh. -- Webmail for Dialup Users http://www.isp2dial.com/freeaccounts.html -- http://mail.python.org/mailman/listinfo/python-list
ANN: dh, the daemon helper 2009-09-04
dh, the daemon helper The daemon helper starts any program or script as a daemon. It's a small C program with a simple interface and a liberal license. ftp://ftp.isp2dial.com/users/jak/src/dh/ Get the files and do: make install clean To build and install dh. Don't try to run the Sh.install script directly, it must be invoked using the Makefile. I use dh for starting scripts which read fifos fed by syslog. They block on read until syslog provides data to work on. They never end, and need help to start as daemons. But that's just one example. There are many other potential uses for the daemon helper. dh is its name; a natural companion to sh. I use dh on Linux, but was curious about portability. With some minor changes, I compiled and installed it on NetBSD 5.0.1 x86. So now it's portable. Wheee! It's a cool tool, it reports problems encountered when trying to exec the target daemon program or script. Debian's start-stop-deamon can't do that, nor can any other daemon tool I know of. It's minimal, with only one command line option, -p. Avoiding unneeded bells and whistles was my intentional design. In six months time, I could lose interest in computers, start a new career, and the work would be lost forever. Someone who likes C more than I do should adopt dh and help it grow. But if you do, don't believe what Stevens wrote about ignoring SIGHUP before the second fork(). It's not true, so don't write voodoo code to handle it! See the thread in c.u.p with the subject Orphaned process groups, daemon startup, SIGHUP. If you can't adopt dh, but have ideas for patches, send them. But if I don't respond, well then, you're on your own. There is no man page for dh, but the README explains how to use it. If there is enough interest, maybe someday I will give dh an official version number and use some version control. But for now, the date of last modification is all there is. -- Webmail for Dialup Users http://www.isp2dial.com/freeaccounts.html -- http://mail.python.org/mailman/listinfo/python-announce-list Support the Python Software Foundation: http://www.python.org/psf/donations/
