Course Scan Runs Indefinitely #713

Closed ghost closed 2 years ago

ghost commented 2 years ago

When the course menu item for UDOIT is first clicked, it takes a very long time for the program to appear, perhaps 20 to 30 seconds or so. I attribute this to the fact that it is contacting the Heroku server and may have to spool up. However, once it does appear users see the message "UDOIT is scanning the course content for accessibility issues..." This process seems to go on forever regardless of the size of the course. I have had it run for more than 30 minutes on a course that had very little content. If after a period of time I exit the course and re-enter it and click on UDOIT one of two things will happen 1) it will run a brief scan and then the results will appear or 2) it will start scanning again and continue scanning like it was the first time. I am curious as to why the initial scan seems to take forever and does not complete.

Unfortunately, we're unable to replicate the infinite scanning issue on our end. Do you see anything in the Heroku logs? You can view them by viewing the settings of your Heroku instance, then clicking on "More->View Logs" in the top right.

When I review the logs it looks like it is timing out. I increased the timeout from 15 to 30 but that did not change anything. The strange thing is that it works for some classes but not others. I would think that would indicate the it is configured properly. I attached the log file, not sure if you can decipher anything from it. I’m also seeing a message in the log file “executing too slow”. Is there perhaps some Heroku tweaking that I need to consider?

After doing some research and testing, this issue appears to be a result of our new broken and redirected link detection. Since it's not possible to increase the maximum execution time beyond 30 seconds on Heroku, here is our plan for solving this:

  1. Issue a hotfix that disables the broken and redirected link checker.
  2. Add the ability to enable/disable the broken and redirected link checker either through .env.local or the Heroku app settings. It would be disabled by default for Heroku.
  3. Implement a background worker that would handle all course scanning activity, since Heroku has much longer timeouts for workers.

Hello Jacob,

Thank you for taking time to clarify what the issue is. Also, thanking for taking time to troubleshoot. I assume that working out the details to a patch will take some time. While I await a fix, is there another option for me? The version 2.5 that was previous installed has since ceased to work on my end. This is what lead me to the update. I see that version 2.8 was the last iteration prior to moving to the cloud version however, I cannot locate the folder on GitHub where it is installed. Could you provide a link to it so that I could try installing version 2.8 while I await resolution of UDOIT Cloud? Unless you think that the fix will be coming quickly.

Sincerely, Tom Alway

3.1.1 is released. Please try it out on Heroku to see if it fixes your issue. You can set up a new Heroku instance by clicking the Heroku button. If you have the code downloaded to your machine via Git, you can update your existing Heroku instance of UDOIT 3.1.0 by pushing the main branch to your Heroku's master branch.

If you would like to try UDOIT 2.8.3, you can click the Heroku button in the classic branch.

Wow, that was fast. Thank you. I will give it go.

bagofarms commented 2 years ago

Closing in favor of the worker feature request issue.

I've recently deployed the latest version 3.1.1 and am running into this issue where some courses are scanning indefinitely. No issues with smaller courses but am running into the execution time out with larger courses

I'm not quite sure where to go with this since it works in some courses but not others.

I will add that I used the 'deploy to Heroku' button from the main page and followed the install instructions in HEROKU.md and INSTALL_Canvas_md

It looks like you're experiencing the same issue as the original poster. It is still our plan to implement a worker for Heroku, which will be the solution to this problem
