14 <para>Here are some things that should be done ... Note that some of these
15 entries are just some ideas, which <emphasis>may</emphasis> be done in
17 <para>If you see something you'd really like to see implemented here, feel
18 free to send me a mail: it may make me move it to the top of my to-do list ;) .
20 <para>If you plan to help me, please send a mail at &email; to prevent two
21 people from doing the same thing. You can send me some propositions as
22 well, or ask me to move something to the top of the heap ;) .</para>
24 <title>High priority</title>
27 <para>test the fix for empty mails on non linux systems (solaris seems ok, feedback on BSD?) (starting from fcron 2.9.7 -- no complain so far, so fixed?)</para>
30 <para>bug fix: what happens if the grand-child cannot be forked or cannot run the job in job.c? + better loop to read/write the pid of grand-child from/by the child (fcron freezes if the filesystem on which it operates has no space left? (cannot reproduce it on my linux system)</para>
33 <para>set TZ env. var. for jobs for which option tz is used.</para>
38 <title>Low priority</title>
41 <para>code cleaning: create a .c/.h file for data structures
42 (file/line lists, serial queue, lavg list, exe list),
43 and work with them only through functions/macros.
44 + secure equivalent to str[n]{cat|copy|...}</para>
45 <para>Note: may introduce bugs, so it will be done in fcron 3.1.x, and needs to be tested thoroughly..</para>
48 <para>Mem footprint reduction: use an/some union(s) in CL struct.</para>
51 <para>For environment settings, make a var substitution.</para>
54 <para>add a return code for jobs which would mean that they
55 should not be run again (in case of an error, etc...).</para>
58 <para>Use directory notifications (FAM), and support a fcrontab
59 and a cron.d as Vixie cron does (directly included in fcron itself, not thanks to a script as now).</para>
62 <para>PAM support (included in fcron, but needs more tests by
63 people using PAM - not implemented in fcrondyn: is it needed
64 in fcrondyn anyway?)</para>
67 <para>support for per user serial queue (especially for root)</para>
70 <para>use readline (if available) for fcrondyn.</para>
73 <para>add a mailsubject option, for custom mail subjects (for instance, in case of a job containing something secret -- password, etc -- in the command line).</para>
81 <para>add a system of modules: at startup, fcron loads some
82 modules (.so files). Then, when fcron should run the job, it
83 calls a function of the module, and let it manage the job
84 (threads?). (do linux dlopen(), etc exist on other systems?
85 - yes: thanks Harring ;) dlopen exists on all POSIX system -
86 even windoze - abait it does not use the same insterface of
87 function calls. But it can be easily implemented to port to
88 another system.).</para>
91 <para>(related to the system of modules? create a kind of
92 dependencies?) Add a way to run a job only if a command
93 returns true. It would permit, for instance, to run some jobs
94 on a laptop only if it is on AC power.</para>
95 <para>and depending on the return value of the command, cancel
96 the execution, or wait x seconds before trying again, etc.
97 In this case, needs change the way the jobs are queued?</para>
100 <para>add an option/module to prevent fcron from running a job if the
101 system is running on battery (anacron does it?)</para>
104 <para>Add a way to stop a job (SIGSTOP) if the lavg gets to high,
105 and restart it (SIGCONT) when the lavg has decreased.</para>
108 <para>Add a timeout for task completion: if a task takes more
109 than a specified timeout, then start another script with the
110 initial task PID as argument. That would allow a kill with
111 different signals (-HUP, -TERM -STOP, .... or any other action
112 like sending a mail to sysadmin to alert him/her that a task
113 is taking too much time and that he has to have a look at it.)
114 (add an option to specify the cmd, and combine w/ option until)
