[EP-tech] Antwort: Re: IRStats2. Browsers and Countries

My Perl book (Tom Christiansen, brian d foy & Larry Wall, Programming Perl, 4th ed., O'Reilly, 2012) says on p. 887 that keys returned by the keys function are sorted by the values.

There are two options:

- On line 20 of Browsers.pm, you change the value from "Apple Safari" to "Safari", so Google Chrome matches first.
- or on line 54, you change the loop to

#       foreach( keys %$BROWSERS_SIGNATURES )
        foreach( sort keys %$BROWSERS_SIGNATURES )

which sorts on the keys, so Chrome matches before Safari.

The second option is a little less performant, since it involves a sort operation on each processed record. However, I prefer it.

Have a nice day,

Martin

The code you want is here:

https://github.com/eprints/irstats2/blob/master/cfg/plugins/EPrints/Plugin/Stats/Processor/Access/Browsers.pm#L12

...which probably should exist in a configuration file for just this reason.

The problem is that the Chrome line includes the word 'Safari' -- I'm not sure what the best practice to fix this is.  It's quite possible that the problem is broader than you suspect, so fixing it would make it wrong in different ways.

Part of the problem is also that we're iterating through the keys of a hash, and they order they come out in is undefined, so we can't be sure which browser will get the priority.

We should probably be using a library for this -- something like http://search.cpan.org/dist/Parse-HTTP-UserAgent/lib/Parse/HTTP/UserAgent.pm
