Re: Regex difficulties

[Balázs Szabados <szabados0701@xxxxxxxxx>]

Hi Amos,

I tried troubleshooting you've mentioned. I just enabled one file containing regexes.

I've measured it:
root@OpenWrt:~# wc -c /etc/squid/blacklists/regex_allow
1636 /etc/squid/blacklists/regex_allow

Since the whole file is 1636 bytes, I assume ever line of regexes is in must be smaller than that.

Starting up squid I'm getting these:

2015/05/04 23:17:44| aclParseRegexList: Invalid regular _expression_ '(.*(acoon\.de|openacoon\.de|omgili\.com|youtube\.com|slug\.ch|\/search\?|mister-wong\.de|mister-wong\.com|abacho\.|seekport\.|flickr\.com|altavista|ask\..com|answers\.com|clusty\.com|exalead\.com|metacrawler|dogpile|lycos|google|yahoo|dmoz|search\.|wikise': Unmatched ( or \(

I've created a file with just that part in the error message, and it seems to be 256 bytes (wc -c again).

Isn't that possible, that this is the limit, you've mentioned?

Thanks,

Balazs

Looking at those files, they contain single pattern lines exceeding 2KB
in length.

Squid will not read more than 2048 bytes on any single file line.
Including the line terminator. The result will be that the regex parser
is presented with a truncated line.
