Error send bulk email with ironwood

scwall · November 20, 2020, 9:46am

Hello, I am currently working with a company that collaborates with several universities.

This one uses the ironwood version and they don’t want to change the version because of depreciations that have been brought to the new version. So I have to keep this version up to date and functional for the moment (For the deployment it uses d’openedx it uses tutor).

I have a problem with the use of rabbitmq and the two workers who share cms-worker and lms-workers information.
When I try to send a mass email from a course

cms-worker_1 | File “/openedx/venv/local/lib/python2.7/site-packages/celery/worker/consumer.py”, line 465, in on_task_received
cms-worker_1 | strategies [type_](message, body,
cms-worker_1 | KeyError: u’lms.djangoapps.instructor_task.tasks.send_bulk_course_email

I solved the problem by creating 2 instances of rabbitmq, but I have the tutor creator who explained to me that rabbit must use the same username and rabbit container for both workers.

github.com/overhangio/tutor

Using the same user on the rabbit broker

**Bug description** hello, There is currently a problem with using Rabbit w…hich uses the same login and password with LMS and CMS, I have encountered a conflict when sending mass emails. ``` LMS ---> rabbitmq --> worker-cms |-->worker-lms ``` Here LMS sends the task to rabbit who sends it to the most responsive docker took the message first (CMS) which returned an error that the task does not exist. The LMS worker listened to receive that there was a task but received nothing neither task nor error. To fix the problem I used a dirty way to do it in the meantime, I used the plugin system and overide the configuration file and now everything works. The two ways I see are either the same docker rabbitmq and two different identifiers created in the Dockerfile , or leave two separate rabbit containers for each worker. my current plugins ``` name: tworabbitdockers version: 0.1.0 patches: lms-env: | "CELERY_BROKER_HOSTNAME": "rabbitmq-lms" cms-env: | "CELERY_BROKER_HOSTNAME": "rabbitmq-cms" local-docker-compose-services: | ########### LMS and CMS rabbitmq rabbitmq-lms: image: docker.io/rabbitmq:3.6.10-management-alpine volumes: - ../../data/rabbitmq:/var/lib/rabbitmq restart: unless-stopped rabbitmq-cms: image: docker.io/rabbitmq:3.6.10-management-alpine volumes: - ../../data/rabbitmq:/var/lib/rabbitmq restart: unless-stopped ```

Here there would be a solution that would have been put in place to make the sharing problem work:

with this patch :
https://github.com/edx/edx-platform/commit/adb2c672e4d17cc1c42bdc206a0051e0fa16b5be.patch
https://github.com/edx/edx-platform/commit/b7ecd80a2bef0d845c3bce97818e70fb3ed9e36d.patch

But it seems that the patch is not functional for sending mass emails. I tested several things. But it doesn’t work.

If you have a lead or an idea of a patch I could apply it would be very useful to me.

Thank you in advance
