Craft Commerce: Unraveling The Mystery Of Excessive Product Resaves

by ADMIN 68 views

Hey everyone, let's dive into a head-scratcher that's been bugging a Craft Commerce user! They're seeing a 'Resave Products' queue job kick off on their site, but it's trying to resave a whopping 46,000 products when they only have 900. Talk about a headache, right?

We'll break down the original problem, explore potential causes, and hopefully, give you some solid steps to troubleshoot similar issues if you ever run into them. Let's get to it!

The Core Issue: Unexpected Product Resaves

So, here's the deal: Our user has a Craft Commerce setup with around 900 products. Out of the blue, they're seeing a queue job – titled "Resaving products" (or sometimes "Produkte wiederherstellen") – pop up, attempting to resave a staggering 46,000 products. This is happening in their production environment. The user mentioned they're running a multi-site setup with approximately 120 sites. They're also using Craft CMS 5.8.17, Craft Commerce 5.4.6. Other version details are not provided.

First off, this ain't right! Resaving a ton of products can bog down your site, eat up resources, and generally cause performance issues. The user is on the right track suspecting that the multi-site setup and propagation settings might be the culprits, since in Craft CMS, the multisite feature can sometimes lead to unexpected behaviors if not configured carefully. But, they need to figure out why this job is even running in the first place.

The Puzzle Pieces: What We Know

  • The Job: "Resaving products" or similar wording is running.
  • The Numbers: It's trying to resave 46,000 products, but only 900 exist.
  • The Setup: A Craft multisite with about 120 sites.
  • The Reproduction Attempts: The user tried creating, editing, and deleting products, but couldn't replicate the job's trigger.
  • The Console Command: Running php craft resave/products correctly resaves the 900 products.

Possible Culprits: Where to Start Looking

Alright, let's play detective and brainstorm some potential causes. Since the user can't manually trigger the job through typical actions, we need to think about what else might be causing this.

Propagation Settings in Multisite

This is the biggest red flag, guys. In a multi-site setup, how your content propagates across sites is crucial. If product settings are incorrectly propagated (or not propagated as intended), it could lead to the system thinking there are more products than there actually are, or triggering updates that involve all products instead of only the necessary ones. You gotta make sure your product fields are set to propagate correctly across your sites.

Check these key settings:

  • Field Propagation: In your product field settings (in Craft's settings), review the propagation method. Are the fields set to propagate to all sites, or only specific ones? Incorrect settings here could definitely lead to confusion.
  • Site-Specific vs. Global Fields: Make sure you understand whether your product fields are site-specific or global. Mixing them up can cause a whole host of problems. Global fields will share the same content across all sites, while site-specific fields will have unique content per site.

Plugin Conflicts or Triggers

Plugins can sometimes be the hidden villains. Some plugins might have their own event listeners that trigger actions on product save, update, or other events. They might be inadvertently causing this resave job. So, you need to check these:

  • Plugin Updates: Has the user updated any plugins recently? A buggy update could be the cause.
  • Plugin Interactions: Do any plugins interact with products? Commerce-related plugins (like those for discounts, inventory, or product variations) are the prime suspects. Deactivate them one by one to see if the issue goes away.
  • Event Listeners: Some plugins listen for events in Craft, such as craftase ields egisterFieldTypes (for registering custom fields), or craftaseehaviors egisterBehaviors (for registering custom behaviors). Look through your plugin code or check their documentation to see if they are doing anything that might unexpectedly trigger a product resave. The user's list of installed plugins is not available in the original post, making it harder to diagnose possible plugin issues.

Craft Commerce Core Logic

It's also possible that there's an issue within Craft Commerce itself, even though that's less likely. You'd want to eliminate other possible causes first, but here are a few things to consider:

  • Commerce Updates: Has the user recently updated Craft Commerce? A bug in a specific version might be causing this.
  • Corrupted Data: Though rare, there's a chance something is corrupted in the database. Running database repair commands (from the Craft console or using a database management tool) might help.
  • Custom Modules or Code: The user should check if they have any custom modules or code that interacts with products. If so, inspect that code carefully.

Diving Deeper: Investigation Strategies

Now, let's get into how the user can actively troubleshoot this issue. I'll include some specific things they can do to pinpoint the source.

Logging and Monitoring

This is essential. Implement more detailed logging to capture when the job is triggered and the context around it.

  • Queue Job Logs: Craft has logging capabilities. Configure Craft's logging system to capture more detailed information about queue jobs, including the stack trace of where the job is being called from. Review the logs for clues.
  • Custom Logging: Add custom logging within your plugins or custom code that interacts with products. Log events before and after any product-related actions to track down the trigger.
  • Monitor Production: Set up monitoring tools (like New Relic or similar) to monitor the site's performance and see if there are any spikes or unusual activity around the time the resave job runs.

Debugging in a Development Environment

Trying to solve a problem directly in production is dangerous. Always try to reproduce the problem in a safe environment first.

  • Replicate Production: If possible, create a local development environment that mirrors your production setup as closely as possible (same Craft version, Commerce version, plugins, and data). This will help you identify the root cause faster.
  • Step-by-Step Debugging: When you're in the development environment, use debugging tools (like Xdebug) to step through the code execution. Set breakpoints in Craft's core code, Commerce code, and your custom code to see what's happening just before the job is triggered. Look for the exact function call that's enqueueing the resave job.
  • Isolate the Problem: Try disabling plugins one by one or removing custom code to see if the issue goes away. This is how you find the culprit.

Database Inspection

Inspect the database directly to verify product counts and related data.

  • Check the craft_commerce_products Table: Verify the actual number of products in your database. This will confirm whether the system is truly seeing more products than expected.
  • Review craft_queue Table: Look at the craft_queue table to see if you can see any patterns or clues about the resave job's origin. The ttr (time to run) column might reveal how long the job is taking, and the data column might contain useful information.

Targeted Solutions: What to Try First

Based on the user's situation and our analysis, here are the most important things the user should focus on:

  • Propagation Settings: Carefully review the propagation settings of all product fields. Ensure they align with the user's multi-site strategy and intended behavior. Make sure there isn't any unintentional propagation causing the system to believe that more products need resaving.
  • Plugin Checks: Disable plugins one by one, especially those related to product management, commerce, or site management. See if the resave job stops running. If it does, you've found your culprit.
  • Logging: Set up detailed logging to capture the context around the job's execution. This is the single most important step in figuring out what's going on.

Advanced Troubleshooting: When Things Get Tricky

If the above steps don't resolve the issue, you might need to take things a step further.

Analyzing Queue Job Details

  • Examine the Job Data: When the resave job is running, dig into the queue job details. Craft stores data about each job. Check what data is being passed to the job. This information might reveal the source or reason for resaving the products.
  • Trace the Code: Use a debugger (like Xdebug) to step through the code and trace how the resave job is being initiated. Craft uses a queue system, so you'll need to figure out which code is enqueuing the resave job.

Database Optimization and Integrity

  • Run Database Repair: Use Craft's built-in database repair tools (or a database management tool) to check for and fix potential database inconsistencies.
  • Optimize Database Tables: Ensure your database tables are properly indexed and optimized. This can improve overall performance and help prevent issues.

Craft CMS and Commerce Core Analysis

  • Review Craft Commerce Changelogs: Check the changelogs for Craft Commerce versions that the user is running. See if any bug fixes or changes might be related to the resave job behavior. Sometimes, a bug in an older version gets fixed in a newer one.
  • Compare with a Clean Install: Create a fresh, clean installation of Craft Commerce and see if the resave behavior happens there. This can help isolate whether the problem is specific to your user's setup or a more general issue.

Keeping it Smooth: Long-Term Prevention

Once the problem is solved, it's a good idea to put some measures in place to prevent it from happening again.

  • Regular Plugin Updates: Keep your plugins updated, but test them in a development environment before deploying to production. This helps catch potential issues early on.
  • Code Reviews: Implement code reviews for any custom code or modules that interact with products. Another set of eyes can often catch potential problems.
  • Monitoring and Alerting: Set up alerts to notify you if queue jobs start running unexpectedly. This way, you can catch issues quickly before they cause major problems.
  • Backups: Have a good backup strategy in place, so that you can easily restore your site if needed.
