XF 2.1 Cache contexts that are Enabled by default?

[rdn]

I assume these are all enabled?

• css
• registry
• sessions

By just using this config:

$config['cache']['enabled'] = true;
$config['cache']['provider'] = 'Redis';
$config['cache']['config'] = [
    'host' => '127.0.0.1',
    'password' => 'password'
];

Only page contexts needs manual config addition?

Yes. Each cache call in the code can be configured as to whether it falls back to the default if not overwritten.

The page context does not do this, due to the likelihood that it may evict things like sessions and cause login difficulties if the cache is small or if there are a large number of guests active.

Thanks Mike!

How about Redis?
If I have 'persistent' => true

Do I need to configure 'persistent_id' => 'somestring' ?

Or I can leave 'persistent_id' => '' default?

 

[Mike]

That's really about general Redis connection configuration. If you enable persistent connections and set a persistent_id, the persistent_id will be passed to this: https://github.com/phpredis/phpredis#pconnect-popen If you don't set one, no ID will be passed to that function.

Is it possible to enable/set?

• lua
• serializer as igbinary

on config.php?

From your addon, we can configure:
'persistent' => true,
Is it the same as
'persistent' => true, 'persistent_id' => 'xxxxx'

on XF 2.1?

@Mike
Please take a look at my config:

// Global Cache
$config['cache']['sessions'] = true;
$config['cache']['enabled'] = true;
$config['cache']['namespace'] = 'xf_';

$config['cache']['provider'] = 'Redis';
$config['cache']['config'] = [
    'host' => '127.0.0.1',
    'database' => 2,
    'persistent' => true,
    'persistent_id' => 'global'
];
// Global Cache

// Guest Page Cache
$config['pageCache']['enabled'] = true;
$config['pageCache']['recordSessionActivity'] = false;
$config['pageCache']['lifetime'] = 900;
$config['cache']['context']['page']['namespace'] = 'xff_';

$config['cache']['context']['page']['provider'] = 'Redis';
$config['cache']['context']['page']['config'] = [
    'host' => '127.0.0.1',
    'database' => 3,
    'persistent' => true,
    'persistent_id' => 'page'
];
// Guest Page Cache

Is everything correct?

Thanks!

Yes, with my cache add-on if persistent is string-like it gets used like persistent_id does.
