Cache size

[ghost]

The size of browscap.ini has more than doubled in the last few months. Using v5024, the corresponding php cache file needs about 20M of RAM. We are using a stripped down version of that file in our WordPress plugin, wp SlimStat.

I was wondering if there was a way to split the cache into multiple files, and then loop through them to load only a subset of agents/browsers at a time.

Would you be able to explain the structure of _browsers and _patterns and how they work together to see if we can split them correctly?

There are 4 arrays needed.

1. _pattern: it holds the detection rules from the browscap file, but quoted to be able to use them with preg_match, the key in this array is the regex, the value is the key in the _browsers array
2. _browsers: it holds the values from the browscap file, the property names are replaced with their keys from the _properties array, the property value of the parent property is replaced with their key of the _useragents array
3. _properties: it holds the properties from the browscap file
4. _useragents: it holds the values (names) of the parent property

I hope I explaned it right.

Could you tell what kind of browscap file you use (lite, normal or full) ?

What we ended up doing in WP SlimStat [ https://github.com/getusedtoit/wp-slimstat/tree/master/databases ] is to split the initial ini file into 5 chunks, and then run phpbrowscap on each of them to create the corresponding cache.php. Then we simply loop through the files until we find a match. Memory usage went from 20M to 2M!

If you like, create a feature request on https://github.com/browscap/browscap to let you create these splitted files. Then dont need to do this after each update.
