<para>Use directory notifications (FAM) / inotify, and support a fcrontab

However the parsing work is done by fcrontab, and should probably keep on being done by fcrontab for

security and stability reasons: have fcron call fcrontab to do that job?</para>

<para>add a system of modules: at startup, fcron loads some
|
|
modules (.so files). Then, when fcron should run the job, it
|
|
calls a function of the module, and let it manage the job
|
|
(threads?). (do linux dlopen(), etc exist on other systems?
|
|
- yes: thanks Harring ;) dlopen exists on all POSIX system -
|
|
even windoze - abait it does not use the same insterface of
|
|
function calls. But it can be easily implemented to port to
|
|
another system.).</para>
|

</listitem>
|
|
<listitem>
|
|
<para>(related to the system of modules? create a kind of
|
|
dependencies?) Add a way to run a job only if a command
|
|
returns true. It would permit, for instance, to run some jobs
|
|
on a laptop only if it is on AC power.</para>
|
|
<para>and depending on the return value of the command, cancel
|
|
the execution, or wait x seconds before trying again, etc.
|
|
In this case, needs change the way the jobs are queued?</para>

<para>add an option/module to prevent fcron from running a job if the

system is running on battery (anacron does it?)</para>

<para>Add a way to stop a job (SIGSTOP) if the lavg gets to high,

and restart it (SIGCONT) when the lavg has decreased.</para>

<listitem>

<para>Add a timeout for task completion: if a task takes more
|
|
than a specified timeout, then start another script with the
|
|
initial task PID as argument. That would allow a kill with
|
|
different signals (-HUP, -TERM -STOP, .... or any other action
|
|
like sending a mail to sysadmin to alert him/her that a task
|
|
is taking too much time and that he has to have a look at it.)
|
|
(add an option to specify the cmd, and combine w/ option until)
