Moving to GitHub, slowly

The software on this pages will slowly be moved to GitHub https://github.com/hilbix/. The CVS repository will be migrated to GIT as well, so the history will be preserved, a bit. See FAQ.

Scylla and Charybdis, timestart - Tools

The tools are developed under Linux with ESR's paradigm release early, release often in mind.
So you can consider this beta software, or alpha, or pre-alpha, or even worse ;)

Have a look in the download directory for all downloads.
As always here, all you get is the source. No binaries here.

timestart 0.1.0-20111013-022104

Start a program N-M times in parallel by running it it each A-B seconds

⇒ ⇒ ⇒ The development shifted to another location. All future versions will be published at https://github.com/hilbix/timestart   ⇐ ⇐ ⇐

timestart N M A B program tries to keep N running programs in parallel. The interval between program execution is adjusted accordingly.

timestart keeps some bounds, it never executes more than M programs in parallel and the interval is kept between A and B seconds.

If the program not returns 0 (or true), the next invocation is delayed B seconds, but this has no influence on the calculated interval.

Also following signals are honored: SIGHUP makes the program terminate after all childs are finished; SIGUSR1 halts the spawning of new programs; SIGUSR2 continues and immediately spawns a new program; SIGWINCH print statistics to stderr

Note that timestart will run more than M programs if SIGUSR2 is sent more often, as these signals are meant to help in debugging. Signals to parent processes can be sent easily using $PPID, so the child tasks can control timestart a bit.

The debug output of timestart is written to FD3 if this FD is redirected somewhere.
