# 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)
