Item10637: Allow IP addresses to be supressed from logs

Implement SupportStrippingIPsFromLogfiles

-- GeorgeClark - 15 Apr 2011

CharlesAdicke: I can work on implementing this for 1.1.4 unless you are interested in committing your fixes. I'd like to make the config option {Log}{SuppressIP}, with default or missing as false, to minimize any impact on installed sites.

-- GeorgeClark - 15 Apr 2011

Yes George, please go ahead with your implementation. Thanks a lot for taking this over!

this is a good (and sometimes necessary) feature, but i wish it would go through some sort of "plugin function"/api. that way, an anonymizer could be implemented, not simply a stripper.

Resetting the clock on the feature proposal, so this can be discussed a bit more.

Thats true too. Do you see the need for an API instead of an binary strip/no-strip option? Otherwise I would suggest first going with the option and if the need arises an API function for the logging could be implemented. No need to implement an API maybe nobody needs.

Implementing this as a new logger type Foswiki::Loggger::PlainFile::Obfuscating. It can either mask the IP (x.x.x.x) or obfuscate it by replacing it with the first 4 bytes of the md5 hash of the original fileld. Will commit to 1.1.4 since the new logger type shouldn't cause any issues if not chosen, it's low risk.
