1.5. Todo

   Here are some things that should be done ... Note that some of these
   entries are just some ideas, which may be done in the long run.

   If you see something you'd really like to see implemented here, feel
   free to send me a mail: it may make me move it to the top of my to-do
   list ;) .

   If you plan to help me, please send a mail at <fcron@free.fr> to
   prevent two people from doing the same thing. You can send me some
   propositions as well, or ask me to move something to the top of the
   heap ;) .

1.5.1. High priority

     * Option to compile and install from git sources without generating
       the doc
     * use ask_user() in boot-install
     *

1.5.2. Low priority

     * Add unit tests using some unit-test framework (turn the tests/*
       code into unit tests)
     * For environment settings, make a var substitution.
     * add a mailsubject option, for custom mail subjects (for instance,
       in case of a job containing something secret -- password, etc -- in
       the command line).
     * Use directory notifications (FAM) / inotify, and support a fcrontab
       and a cron.d as Vixie cron does (directly included in fcron itself,
       not thanks to a script as now). 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?
     * could be worth checking fcron for memory leaks using specialized
       library (just in case...)
     * option to put a maximum limit on the execution time of a task +
       terminate it if not finished yet + send email to let the user know
     * setting to limit the number of jobs of a single user in the
       serialq/lavgq to X jobs + make sure root always has Y slots that it
       can use in those queues (i.e. number of slots used by root + number
       of free slots >= Y)
     * Test (and use ?) docbook2x-man -- xlstproc ? cf
       http://antoine.ginies.free.fr/docbook/ch09.html
     * find way to have the non translated pages of the French translation
       be updated automatically (changes, todo, etc -> copied from the
       English doc)
     * add a return code for jobs which would mean that they should not be
       run again (in case of an error, etc...).
     * PAM support (included in fcron, but needs more tests by people
       using PAM - not implemented in fcrondyn: is it needed in fcrondyn
       anyway?)
     * support for per user serial queue (especially for root)

1.5.3. Ideas

     * 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.).
     * (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.
       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?
     * add an option/module to prevent fcron from running a job if the
       system is running on battery (anacron does it?)
     * Add a way to stop a job (SIGSTOP) if the lavg gets to high, and
       restart it (SIGCONT) when the lavg has decreased.
     * 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)
