What built in TCL commands are disallowed in iRule?

Hi Philippe,

keep in mind that the list above is also containing certain TCL commands (e.g. [interp], [pid], etc.) which are still disallowed by LTMs iRule syntax checking which is enforced during iRule savings. Those commands would require special iRule codings techniques to not expose those commands during iRule savings.

E.g.:

The iRule below wont save:

when RULE_INIT {
    log local0.debug "The PID of the TMM[TMM::cmp_unit] process is: [pid]"
}

The iRule below will work fine:

when RULE_INIT {
    set cmd {
        log local0.debug "The PID of the TMM[TMM::cmp_unit] process is: [pid]"
    }
    eval $cmd
}

Cheers, Kai
