Chronic
view release on metacpan or search on metacpan
- SIGHUP handling was augmented to defer signals during task
execution since tasks can't be safely interrupted. HUP is
turned off before execution and replayed once the task is
finished running.
- The scheduling algorithm was modified such that scheduler
sleeps are completely controlled by ``wait'' times
returned by constraints; the scheduler does not sleep for
a ``timestep'' like it used to. The scheduler can also
function when there are no tasks in the chrontab; it will
simply sleep till a task arrives.
0.20 (June 30, 2004)
- SIGHUP handling was introduced in chronicd. On receipt of
a HUP signal, chronicd will drop the existing schedule,
re-read config files and start over again.
- Capability to run certain tasks "only once" was added
to the Scheduler. When ``only_once'' is set to 1 in
the config file, chronicd will run the task once.
chronicd will purge these tasks from the chrontab once
they've been run.
- Notification functionality augmented to inform the user of
failures. If return value of the program is not 0, a
failure is assumed.
0.15 (June 04, 2004)
- Introduced the "InXs" constraint that combines the
Inactivity constraint and the Xscreensaver constraint
using an OR relationship.
- Scheduler wait doesn't exceed 10 minutes. This is because
a machine can hibernate (or chronicd backgrounded) in
middle of a long sleep, causing scheduler_wait to exceed
the intended sleep time. An upper limit ensure that
chronicd will "self-correct" its timers every 10 minutes.
- Added support for email notifications. notify =
email@address as a task field will send notifications to
email@address. Time values in the email notification are
in human readable format. eg. 35 seconds, 4.52 days, etc.
[Feature Request #946816]
- Fixed a bug in chrontab re-writing logic. We were missing
the final ";" which could've caused a corrupted chrontab
in certain cases.
- Added a template constraint module under the docs
directory. The template will act as a starting point for
writing new constraints.
0.10 (May 15, 2004)
- Introduced a Xscreensaver constraint that is met when
Xscreensaver is locked for a specified amount of time.
chronicd manpage updated with Xscreensaver documentation.
[Feature Request #952966]
- Added a basic use test to satisfy CPAN's automated
testing. A more comprehensive test suite will be
provided someday.
0.02 (May 11, 2004)
- First public release.
