Queue

This add-on for Broadcast enqueues posts and processes them in the background, which circumvents WordPress and PHP time limits.

Automatic processing is done via AJAX when the user is viewing the post in the editor or in the post overview.

The queue can also be processed via a cron job, see the HTTP processing settings tab. It is recommended that you disable AJAX queue processing and just use HTTP processing.

FAQ

What is the limit?

Queue has been tested with a post broadcast to over 3500 blogs. It took a while (it was left overnight) but it got done.

Also tested with two posts queued to the same amount of blogs: 7000 queued posts.

Why is the queue not being filled?

Perhaps you have selected too many blogs for PHP to handle, together with all of the other post editing data that the server needs to accept. See the PHP max_input_vars setting.

A way to test for this is to use the Send To Many add-on to broadcast the post from the post overview. If the queue fills using Send To Many, then it’s probably the above PHP setting that needs to be modified. Or you can just continue using the Send To Many add-on to broadcast the post.

If you receive an Unable to save Broadcast queue data item error message, try raising your max_allowed_packet Mysql setting.

Why is the queue not being processed properly?

If you find a post is not disappearing from the queue after being processed, it’s probably due to an error during broadcasting.

In order to find out what the problem is:

  • disable automatic processing of the queue in the settings
  • enable WP_DEBUG
  • enable Broadcast debug to browser mode
  • manually process the item in the queue

You should see a long debug text. An error message should appear at the end, telling you what is wrong.

If you need help deciphering the debug dump, contact Plainview Plugins.

    Notes

    HTTP processing

    During a call to the HTTP process URL (preferrably by a cron job) the items in the queue will be processed until either of the following limits are reached:

    • The items per process limit it hit.
    • There is less than 25% of the PHP maximum execution time left.
    • The average time to broadcast an item so far in the process exceeds the PHP execution time left.

    If you find that the queue is not processing your very large posts (lots of images that need to be copied, for example) then set the items per process setting to just 1 post.

    Keep queued posts

    When queuing a post, any old items in the queue related to this post are purged.

    So if a post is being broadcasted to 100 blogs, and then the post is requeued without the queue having finished, all old items are removed before the new 100 items are placed into the queue.

    Retries

    If you wish to limit how many times a post is processed in the queue, perhaps as a way to detect memory or timeout errors, change this setting. Usually, Queue will try and process and reprocess until it works.

    If the limit is reached, the admin will receive an e-mail explaining the queue process error.
