Hi there,

I doing a relay script, but I need help in setting a repeated spam protection. As in if there is repeated text, the script won't repeat the same text for a certain time.

How can I go about doing this?

Hi all,

I did a repeat spam in it, however, it is unable to process fast enough for the huge amount of data flowing through it. How can I further improve the repeat system, I am currently using timer for it.

[nml375]

Possibly use separate variables, rather than multiple variables in a list (repeat).

There is a conditon in your script that might cause multiple timers to unset the same array index. Although having pending timers does'nt take processing-time in itself, the unset command would be called numerous times, blocking other executions.

Could the queue-system (with throttling) be an issue?

Hi there,

Thanks for the reply. I notice another problem, if a user repeat 5 lines within 1 or 2s. The check won't be fast enough to consider them as repeat. I will look into the variable you mention.

Hi there,

Thank you for the advice, it is indeed the timers that been created without control that is causing the problem. I did a check on the timer to make sure it don't exist before creating them. However, is there a better way to do this timer check as it is slow to loop through the timers as I did them.

[nml375]

I guess an ugly check would be to simply use "string first" or "string match", and skip the foreach loop. Not sure how much performace you'd gain however.

One thing that might improve it slightly, is to replace your "string match" with "string equal", since the latter does a character-by-character comparison, and does'nt care 'bout wildcard matching.

Another ugly hack might be to assume there is a timer already running, if "repeat_count($iphost)" already exists upon entering the proc, as a previous invocation would've started the timer if repeat_count($iphost) had been set, and if the timer had completed, repeat_count($iphost) would've been unset.

Hi there,

Thank you for your advice. I have decided to go with check of "repeat_count($iphost)" and assume if it exist then there will be timer exist as well. It will be more efficient in performance compare with the loop check in timer. So far, there isn't any problem running it. Once again, Thanks.

May you tell me what problem you want to solve with that script (relay what?)?

Hi there,

Thanks for offering your help. I have found yet another bug in the script. Since the relay script uses socket to connect to another IRC network. All data is in its RAW form. I notice a problem in PRIVMSG raw where when there is braces "{ or }", the script will end up in error. I tried using regular expression to remove the "{ or }", it don't seem to works. Any suggestion in doing this? All RAW data is in this variable call "$arg".

Hi there,

I read through some stuff and it seem split is able to fix the problem. I have add it into the script and see if it fix it.

If you get errors such as that, it usually means you are mixing lists and strings. Although split does fix these issues at some times (especially when you use list commands on strings), it's really important to understand why you should use split in certain situations.

Simply put tho, commands such as lindex, lrange, lreplace, foreach, join and many others (check their respective manpages) operate on lists, and might break on strings.

Commands such as "string" are generally not list-safe, that is, if used on a list it might damage the list-structure, rendering it unusable as list (causing lindex, etc to break)

Hi there,

Thanks for the reply. I have added split to most "lindex". After going through the third time. I notice I miss out one split on one of the lindex. I added it and it seem to be running smooth now. It still need more testing though. Now I got another question, will quote cause error to script?

Regards,
Lu5ck

[nml375]

First off, don't use split just because you use lindex. Only use split if you need to convert a string into a list. That is, keep track of wether the data is a list or a string. Using split on lists may result in undesired results aswell.

"" is used as bounds of data that should be preprocessed, doing variable, command, and escape-evaluations. Any " within such data-block must be escaped.

A perhaps better description might be found here

Hi there,

Thanks for the info. Yes, I didn't add split to all "lindex". To be accurate, I add them to "lindex" that need to process the "$arg" and all variable that related to that. I guess I need to rephrase my question regarding the quote. If there is quote in the variable call "temp", will it cause error to script?

Regards,
Lu5ck

[nml375]

To be honest, I can't even find the variable "temp" within the piece of code you've posted...

Generally, quotes should not cause problems with neither lists or strings..
Of course, this code will fail, but due to incorrect structures...
