[UNRESOLVED] Bind error

2003-12-05T12:09:10-04:00

trying to add this to the source directly.

Then there's also "do_tcl" starting at line 699 in tcl.c (used by timers, the old need-chansets and the old init-server)
I wouldn't bother trying to implement it in the current dns module as it's being rewritten to fix some concatenation issues (I think...correct me if i'm wrong).
PS: you might want to add "UNRESOLVED" to the subject of this thread to get the attention of some c coder

[UNRESOLVED] Bind error

2003-12-05T09:58:51-04:00

maybe thats a feature for the next eggdrop release...

i'll try to do this without that much recode of my scripts, trying to add this to the source directly.

[UNRESOLVED] Bind error

2003-12-05T03:55:47-04:00

ok, let me se if i get this right...
this code replaces the original "bind" proc, right ?

Yes. So any proc called by a bind leading to an error would have the error displayed by the bindEval proc.

it's no the target to catch an error invoken with a bind, it's to catch every error (timers, etc).

That also involves code run based on binds. You'd also have to replace after,timer,utimer,fileeven,dnslookup,source and maybe some more to catch all possible errors. To make this a bit easier on your bot, you could start using namespaces for your scripts and have a debug namespace with these commands replaced that you can source scripts into to debug them. (you'd need to replace commands removing/listing these callbacks too of course...).

In an ideal world eggdrop would call bgerror (Tcl_BackgroundError) when there's errors in code run by timer,utimer and dnslookup. Then you could just make a proc by that name to have all the async errors displayed. (tcl's internal callback commands call 'bgerror' if it exists)
In an ideal world eggdrop would also invoke 'info complete' (Tcl_CommandComplete) before creating binds/timers, so you would not have to wait for an event to happen to get errors about missing braces and such in your command.

it's my fault, i maybe didnt make the question that clear:

ah, damn, it's too late allready, got to catch a reading by the inventor of Knoppix, i'll check back in the evening

nobody is perfect except user

Hehe...you need to pay more attention ;P

i've been searching for a way to catch this errors and puting them onto the botnet. bla bla bla

This might give you some new ideas

Code:

if {![llength [info procs bind]]} {# rename the bind commandrename bind realBind# make our own that rewrite the command part to call our own bindEval procproc bind args {if {[llength $args]==4} {eval realBind [lrange $args 0 2] [list [list bindEval [lindex $args 3]]]} {realBind;# lazy way to produce the right error message :P}}#proc bindEval {cmd args} {if {[catch {eval $cmd $args} re]} {# this is where the error is displayed...# the lrange thing is to remove any trace of this proc in the messageputlog "Error: [join [lrange [split $::errorInfo \n] 0 end-3] \n] (invoked by a bind)"} {set re}}}

If you need the type,flags and/or mask displayed in the error message too, just pass them along from 'bind' to realBind like i did with the real command to be called. Let's hope I made a mistake so you'll stop thinking i'm perfect
And in case you didn't get it; make sure this script is loaded before the binds (calling procs you are debugging) are made

I'm currently working on my botnet, but when debugging scripts i often get TCL Errors (nobody is perfect except user).

i've been searching for a way to catch this errors and puting them onto the botnet.
but : there is no bind error

TaKeDa from #eggdrop@IRCNet provided me some nice code, but it would still require to modify every proc in my whole code.

then i thought there meight be a way to catch this with a new bind.
when looking at eggdrop .15's source code i found "static int trigger_bind(const char *proc, const char *param)" (tclhash.c, line 668), i think that would be the point to add a callback / whatever, but i cant code in C, so i'm asking here if anyone has allready done it or is willing to do it.
