Re: [SMARTY] Cache cleanup

The external file has to know your environment: where template_dir and cache_dir is for example. It basically needs the smarty object passed to it, so it would be better to include the script and call a function. But then we're back to the processing time issue. Gary Loescher wrote:

I should have seen this coming :-) OK, but when the file check _does_ happen, it will cause noticable lag time... unless we can make the script release it's connection to the browser and then perform the cleanup and exit. I don't know if that is possible (?)

I think it might be possible to write the cache cleanup as an external file and execute it with system() or popen(), as long as you redirect stdout to a file (or /dev/null, etc) PHP won't wait for the command to finish executing and will continue page processing normally. Hmm... possible file-locking problems if cleanup is occurring while Smarty is accessing the cache?

* Should both cache and compile files be periodically cleaned?

I would vote for yes with an option for one, the other, or both.

* Should this be part of the engine, or an optional plugin?

Plugin, since some will want to use a cronjob/batchfile to explicitly control cleanup behavior. But for those that don't want to worry about it, optional plugin would be great, I think. Gary Loescher wrote:

What about setting up a cache cleanup probability variable (ala PHP gc_probability for sessions) that determines when Smarty will clear the cache upon instantiation?

For _every_

the current time and unlink if necessary. It would definately add a

of execution time to the engine. It would be much more efficient to do this via cron: find /path/to/cache -atime +2 -exec rm -f {} \; This doesn't interefere with Smarty execution time either. Windows users would need a different method, maybe a php script to periodically run? Peter Bowyer wrote:

It won't happen automatically. You must do it yourself periodically, either with clear_cache or directly.

Shouldn't Smarty take care of cleaning out old files? Peter -- Maple Design - quality web design and programming http://www.mapledesign.co.uk
