Carabiner 1.0: Asset Management Library

[eluser]tonydewan[/eluser]
I don't know nearly enough about load balancing work to provide anything but pointers. The filenames that Carabiner creates are a concatenation between the last-modified-time (filemtime in PHP) of the most recently modified file, and an MD5 hash of all of the asset filenames (in the group) put together. I'm assuming, then, that the part of the filename that is different is the filemtime string, though I'm not necessarily sure why it would be different (unless your losing resource info when moving to the load balancing servers; at that point, filemtime would probably show as when the file was moved to the server.) If that is indeed the problem, a simple (but not necessarily scalable) solution (assuming you're on Unix) would be to run this command on whatever the most recently modified file is:

Code:

touch -mt 0711171533 /PATH/TO/ASSETFILENAME.js

where 0711171533 is a Unix timestamp.

Otherwise, you'll need to come up with a better way to create unique filenames, or store the filenames in a database. In the case of the former, let me know if you come up with something. In the case of the latter, I would store the MD5 hash as your key, and then when a new file is created, store that filemtime. Then, every time a file is to be created, check for the hash, and if the filemtime is less than an hour (or whatever) older than the one you have, use the one from the DB. Of course, that puts more load on the databse, which in the long run is not the best plan.

If I come up with something better, I'll let you know.
