turn cache on ( the same as on the admin/settings/performance page )

i suggest using sql query command to disable query cache. drupal page cache maybe disabled with new vset command. it might make sense to add a specific cache related command - not sure.

lets rely on vset for now.

For other folks who might be wondering like I was...

drush vset cache 0

Then choose 1.

Funny this issue got bumped recently. I wrote some shortcut commands for enabling and disabling the different caches a couple weeks ago and have found myself using them a lot. I hate to revive a dead issue, but this simple functionality saves a lot of time during development. I think this patch should cover it if you'd like to reconsider.

Didn't test yet, but the code looks good. I'm in favor of committing this here, but if moshe doesn't want it, I'll take it in drush_extras.

I could go either way on this functionality, but it's incomplete as is. Page cache isn't on/off, there are 3 potential values there (4 if you're on pressflow), so those should be represented as well.

Thanks for the feedback. Rerolled the patch to have an option for page cache, and also to be more flexible in how variables and values are specified. I'm looking at the negative value devel module's devel_rebuild_theme_registry as an example of where this could be useful. Also, I'm not sure what level of support Drush wants to maintain for Pressflow, but using 'external' for a page cache option will currently work.

Maybe you could check if the CACHE_EXTERNAL constant is defined and only display it then?

Good idea. It's not a display issue, since it's an option, but I don't think anything good would come of a non-pressflow site being set to cache external.

This actually looks pretty nice to me now. Needs unit tests. See the /tests directory for examples.

Could this be one command rather than two? The drush command listing is getting rather large. Something like the following? That would also save you the wrapper functions.

drush cache js 1

Might be good to liste the types of caches available to enable/disable (page, block, css, js, etc).

Any thoughts about a: cache-disable -aggressive, which would disable all possible cache variables?

$conf['cache'] = FALSE; //page cache
$conf['block_cache'] = FALSE; //block cache
$conf['preprocess_css'] = FALSE; //optimize css
$conf['preprocess_js'] = FALSE; //optimize javascript
$conf['advagg_enabled'] = FALSE; // advagg module
$conf['views_skip_cache'] = TRUE; // views cache

drush vset cache 0

Then choose 1.

Now we may use:
drush vset --exact cache 0
