issue with object-cache

[mxmkmarquette]

when i tried to create a new post it turn into loop and then error 500. when i tried to delete plugin it do not delete it.

both was when i was using memcached and memcache.

when removing the object-cache.php i was able to return to create a new post and also delete plugin. but when i tried to post it's telling me this 397 plugin.php

[chasecmiller]

Perfect. Thanks. I have a line dump listed there to help me debug it that was triggered on your end. I'm trying to emulate the 500 error first. The plugin currently does not uninstall advanced-cache.php or object-cache.php.

[mxmkmarquette]

me i just add to install crumbls-cache, with advanced and object-cache, set the thing, then tried to go into the admin bar or in the section to create or add a new post and i got the error 500.

and thank by the way for you hard work and for taking the time you take to make this magnificient plugin work like you are awesome my friend.

[chasecmiller]

Have any error log info on the 500 error? Thanks!

I just pushed an update to get rid of the 397 and line stop right after it to allow deleting by tags.

[chasecmiller]

Adding in a quick dump to loggly to help me debug this. It will hopefully give us enough info to troubleshoot it.

[chasecmiller]

I added in logging. Next time you use the latest, your error logging will temporarily dump over to Loggly so I can get more information about what's going on. Hopefully it works well. Haven't ever used it on a 500.

[mxmkmarquette]

i just activate the big gun to find the problem that's what i get. // Enable WP_DEBUG mode define( 'WP_DEBUG', true );

// Enable Debug logging to the /wp-content/debug.log file define( 'WP_DEBUG_LOG', true );

after have activate // Use dev versions of core JS and CSS files (only needed if you are modifying these core files) define( 'SCRIPT_DEBUG', true );

directly on the page where i had error 500 now i have

[mxmkmarquette]

but the bug happen even if i just use memcache OR memcached.

[mxmkmarquette]

and on my index is blank now and

phpFastCache\Drivers\Memcache\Item Object ( [fetched] => [driver] => object(phpFastCache\Drivers\Memcache\Driver) [key] => eff8c606309c715c01a18793258c8e1a [data] => [expirationDate] => DateTime Object ( [date] => 2017-04-11 12:36:45.000000 [timezone_type] => 3 [timezone] => UTC ) [tags] => Array ( ) [removedTags] => Array ( ) [isHit] => )

[chasecmiller]

Yeah, it is complaining about memcache and memcached being installed at the same time. That can cause conflicts with PHP.

The real error there that is breaking is decrement on integer. Looking at it now.

[chasecmiller]

I just submitted a new push to finalize the two methods that were breaking, which handle increasing and decreasing numbers in the cache. The warnings are not a big deal at the moment.

[mxmkmarquette]

perfect gonna test it right now.

[chasecmiller]

Sorry, if you just pulled, hit it again. I had left a debug line in there that would be breaking your page.

[chasecmiller]

I'm seeing a few errors, but with the quick and dirty error reporting, it's hard to know exactly where they are coming from. Most of them appear to be from a theme or other plugin. Next time I submit a push, I'll make the logger include the filename so we can get more relevant information.

OT. You're getting a few thousand warnings about a constant not being defined, it's named alpha_length

[mxmkmarquette]

right now that's what i'm getting

[chasecmiller]

And that's on a memcached transient it looks like. Let me switch to memcached and see what I can do there.

[mxmkmarquette]

perfect no problemo my friend take your time... there no hurry and also i don't know if it's a bug but like if i switch from memcached to memcache for anything, the config.php don't update, i need to delete it then it get autogenerated and it add some field.

also what's the difference between ip and host into the cache... like do i need to setup both or just one.

[chasecmiller]

You're going to get to ignore both of those pretty soon. I'm adding multiserver support right now.

[mxmkmarquette]

wow things becoming real up in here!!!

[chasecmiller]

Right now, it's ugly. The GUI is ready for some more clean ups. There is a field called servers for memcache and memcached. Format would be like this:

server.com:port,serverip:port,etc

You can do as many as you want. That provides memcache(d) server settings. If none are provided, it defaults to 127.0.0.1:11211

Pushing now.

[mxmkmarquette]

ok but me my server like memcache, memcached and redis are all on 127.0.0.1:11211, 127.0.0.1:11212 and 127.0.0.1:6379 so what will i enter like bot madmax.quebec:port,ip:port,etc

[chasecmiller]

That's correct. For now. I'll end up making a multiline field, but just haven't gotten there yet.

[mxmkmarquette]

is that normal that my config.php look like this

<?php return array (
  'crumbls_cache_type_page' => 
  array (
    'type' => 'memcache',
    'compress_data' => 'true',
    'path' => '/home/madmax/public_html/neufsvies/wp-content/cache/crumbls/',
    'host' => '127.0.0.1',
    'port' => '11211',
    'servers' => '127.0.0.1:11211',
  ),
  'crumbls_cache_type_object' => 
  array (
    'type' => 'crumbls_cache_type_page',
    'compress_data' => 'true',
    'path' => '/home/madmax/public_html/neufsvies/wp-content/cache/crumbls/',
    'host' => '127.0.0.1',
    'port' => '11211',
  ),

    'host' => '127.0.0.1',
    'port' => '11211',
    'servers' => '127.0.0.1:11212',
  ),
);

[chasecmiller]

Just to check, you're running memcache and memcached? It's saying memcache for pages and object cache, but transients get memcached.

[mxmkmarquette]

i'm running memcache for page cache, inherit from page for object and memcached on port 11212 for memcached, and i have a lot's of difficulty to access either a new post or the admin section

[mxmkmarquette]

let me test if i use all one or all the other

[mxmkmarquette]

if i set all memcache, it's slow like it's taking around 7 secondes to load a page, but when it's render i can go back and forth and it's fast as hell, but i cannot add post.

when i tried to add a new post it give me error 503 backend error and accessing /wp-admin/ is slow as hell.

[chasecmiller]

Have a log of the 503?

What if you switch to 100% memcached? Just for testing a theory.

I don't know enough about regular memcache, but from what Google results say, it sounds like the server is dropping off. Looking into it a little now.

[mxmkmarquette]

if i set all memcached it's more rapid take about 5 second to load instead of 7 to 10 second a new page like if i open a post in a new tab or if i go on page 2, but i still cannot add a new post cause it's like it's timeout but error 503

Error 503

Backend fetch failed

Request ID 1491929280.10038690

and what is strange is that i can edit post and update them but not add/create a new post

[mxmkmarquette]

and i tried to activate the wp debug and else and all what contain the debug.log

is this thing:

even when it's timeout 503

[chasecmiller]

Yeah, the enqueue isn't a problem with our code and wouldn't cause a 503. The 503 is coming from the cache server either not responding or responding too slowly it looks like.

https://www.quora.com/What-does-Error-503-Backend-fetch-failed-mean-and-why-would-it-appear

[mxmkmarquette]

yeah and everything is working good on my side cause if i switch from like crumbls to like wp-ffpc or bat cache witch is a memcached and memcache caching plugin i got no problemo.

[chasecmiller]

I'm having a hard time duplicating it. I am getting 0.20 responses left and right. Posting with some adjustments.

[mxmkmarquette]

maybe you can log into mine and check or i don't know i can provide root access maybe it will tell you what's wrong with that cause me i don't know where to check i tried to activate the debug log and it's telling me nothing that worth investigate.

[mxmkmarquette]

and the last error i have is.

[chasecmiller]

Had to look at the source and I was off base there. At that point, it's asking the cachemanager from php to validate any cache types. Doing a little digging right now.

[chasecmiller]

If you still wanted to set me up with ssh or even ftp, we can dig through this pretty quick. I changed the logging functionality a little to give me more info about what this variable returns.

[mxmkmarquette]

ok regive your email i'll send you the details there without any problem my friend

[chasecmiller]

chase@crumbls.com

Thanks!

[mxmkmarquette]

send my friends :)

[mxmkmarquette]

by the way the cache seems to cache the group "transient" but does it cache also "site-transient" could be a great addition if not.

like combining both of those groupe into the transient option

[chasecmiller]

Was breaking due to a warning that was triggered due to memcache and memcached running in tandem. Changed warning to admin warning. Pushed.

[mxmkmarquette]

good job bro you the best
