Upgrade page empty

BryanV · December 2, 2021, 7:53pm

I got a notif today about upgrading, but navigating to the upgrade page, I find it is blank:

I see there are several threads about this, and the concensus seems to be to manually rebuild. But the thing is I literally performed a manual rebuild two days ago, when I installed a custom Onebox plugin I just wrote:

I’d like to understand why this blank page is happening. Is there something amiss with my trivial plugin that caused this, or that I need to change? Is it unrelated to the plugin, and if so, what I can do to avoid this situation in the future?

JammyDodger · December 2, 2021, 8:22pm

Does it happen if you disable the plugins in safe-mode? That may help you narrow it down.

[YourSite]/safe-mode

BryanV · December 2, 2021, 8:36pm

The /upgrade link is no longer present on the safe-mode /admin page and trying to navigate there manually does not work

Oops! That page doesn’t exist or is private.

JammyDodger · December 2, 2021, 8:50pm

If you untick ‘disable all plugins’, but leave the other two, it’s there. Disabling the official plugins will disable docker-manager, but you should still be able to check themes and unofficial plugins, if that’s any help?

Steven · December 2, 2021, 9:12pm

Do you have any red alert in the console if you type F12 in the upgrade page?

BryanV · December 2, 2021, 9:16pm

@JammyDodger Ah, thank you. No that does not help, the upgrade page is completely blank, even in safe mode with themes and unofficial plugins disabled.

@Steven yes, this is in the JS console log

BryanV · December 3, 2021, 12:30am

So, just summarizing, it appears the page is blank due to a 500 HTTP error from an AJAX request to

https://discourse.bokeh.org/admin/docker/repos

Is there a known explanation for this? Is there any corrective action short of a manual rebuild?

Falco · December 3, 2021, 12:44am

If there is a 500 error, there should be a corresponding entry at /logs.

BryanV · December 3, 2021, 1:30am

@Falco Thanks, I was not aware of that endoint. The error is

One of the plugins you have installed has a nil name somehow

github.com

discourse/docker_manager/blob/4e06649d32fe7af4841d63049a84f28a01df8dfd/app/controllers/docker_manager/admin_controller.rb#L40

    
      
            result = {
              name: r.name,
              path: r.path,
              branch: r.branch,
              official: Plugin::Metadata::OFFICIAL_PLUGINS.include?(r.name)
            }
          
          
  result[:fork] = true if result[:official] && !r.url.starts_with?("https://github.com/discourse/")
          
          
  if r.valid?
              result[:id] = r.name.downcase.gsub(/[^a-z]/, '_').gsub(/_+/, '_').sub(/_$/, '')
              result[:version] = r.latest_local_commit
              result[:pretty_version] = r.latest_local_tag_version.presence
              result[:url] = r.url
              if r.upgrading?
                result[:upgrading] = true
                result[:version] = r.upgrade_version
              end
            end
            result
          end

You can run DockerManager::GitRepo.find_all in a Rails console to check where this is coming from.

@Falco Well I guess (assume) that would be my Onebox plugin, though I am not sure why things also did not work in safe mode. In any case I cobbled this one file together from pieces, never having written any Ruby before, if you happen to know how/where I should specify the “name” that would be appreciated:

github.com

bokeh/discourse-bokeh-onebox/blob/main/plugin.rb

# frozen_string_literal: true

require 'htmlentities'

require_relative "../../lib/onebox"

Onebox = Onebox

module Onebox
  module Engine
    class BokehDocsOnebox
      include Engine
      include StandardEmbed
      include LayoutSupport

      REF_REGEX = /^https?:\/\/docs.bokeh.org\/(?:\w+)[\/\w\-\.]+#((?:bokeh\.)[\w\-\.]+)$/
      NARRATIVE_REGEX = /^https?:\/\/docs.bokeh.org\/(?:\w+)[\/\w\-\.]+#([\w\-]+)$/
      matches_regexp Regexp.union(NARRATIVE_REGEX, REF_REGEX)

      def self.priority

This file has been truncated. show original

Falco · December 3, 2021, 2:02am

Maybe follow an example like

github.com

discourse/docker_manager/blob/4e06649d32fe7af4841d63049a84f28a01df8dfd/plugin.rb#L3

    
      
          # frozen_string_literal: true
          
          
# name: docker_manager
          # about: Docker manager for Discourse image
          # version: 0.1
          # authors: Robin Ward, Sam Saffron
          # url: https://github.com/discourse/docker_manager
          
          
if !defined? ::Discourse.redis
            # HACK: make Discourse.redis work on old versions of Discourse
            module ::Discourse
              def self.redis
                $redis # rubocop:disable Style/GlobalVars

BryanV · December 3, 2021, 2:26am

I did refer to several examples, I just would have never guessed the name was parsed out of a comment, and not configured as actual data/code. I’ll update my plugin and rebuild, thanks.
