Nothing is shown under plugin-manager page

[shang...@gmail.com]

Hi All,

I am testing to update Gerrit from 2.13.5 to 3.2.6, after I upgraded successfully, I tested some new plugins, during this period, I found there was nothing under this page {gerrit-url}/plugins/plugin-manager/static/index.html, the things that made me sad as I could not get useful information from error_log.  Can anybody help me out? 

I will show you where am I?

1. The cofiguration in gerrit.config

[plugins]

        allowRemoteAdmin = true

[plugin-manager]

jenkinsUrl = https://gerrit-ci.gerritforge.com

2. All the plugins are readable by Gerrit user gerrit2

I am not sure whether it is a bug or not, I will show you how I debugged it.

Given the domain name is A.com

The gerrit section in gerrit.config, like 

[gerrit]

        basePath = git

        canonicalWebUrl = https://A.com/gerrit/

The httpd section in gerrit.config  like 

[httpd]

        listenUrl = proxy-https://*:8081/gerrit

As we use reverse-proxy, so when I access our Gerrit, the address is like 

https://A.com/gerrit/ in Chrome browser.

Now I will show you how I found an error on my side when I tried to access plugin-manager

Right-click on the page,https://A.com/gerrit/dashboard/self, choose "inspect", select "Network", then click "PLUGINS->Manage" tab, I saw the following links which is related to A.com

auth-check, the Request Headers is https://A.com/gerrit/auth-check

index.html, the Request Headers is https://A.com/gerrit/plugins/plugin-manager/static/index.html

plugin-managers.js, the Request Headers is https://A.com/gerrit/plugins/plugin-manager/static/js/plugin-manager.js

style.css, the Request Headers is https://A.com/gerrit/plugins/plugin-manager/static/css/style.css

?all, the Request Headers is https://A.com/plugins/?all

you will see there is no gerrit word in the Headers of "?all", but if I amend it, it looks like https://A.com/gerrit/plugins/?all and I will get a correct list like

{"account":{"id":"account","version":"v3.3.0","api_version":"3.2.7-SNAPSHOT","index_url":"plugins/account/","filename":"account.jar"},"admin-console":

...

{"id":"webhooks","version":"v3.2.6","api_version":"3.2.6","index_url":"plugins/webhooks/","filename":"webhooks.jar"}}

is there something wrong or bug with plugin-manager?

thanks

That’s a known issue, a fix has been uploaded on [1], it’s in my backlog to review and test it.

Thanks a lot, Luca,  I am looking forward :)

Hi Luca,

I encountered the same issue with the account plugin, when I clicked ACCOUNT->Personel Information, I got a page without user information.

The 404-page https://A.com/a/accounts/self should be https://A.com/gerrit/a/accounts/self in my situation.

Thanks again.

IF you can configure your reverse proxy, add a rule for it :

Apache:

  RewriteRule ^/plugins/.* /review/plugins/%1 [R]

This should work as long as no other up does use /plugins in its urls

[shang...@gmail.com]

Hi, ice,

You are right,  if I set " RewriteRule ^/plugins/.* /review/plugins/%1 [R]" for plugin-manager, I have to set another rule for account plugin like the following:

"RewriteRule  ^/a/accounts/self /gerrit/a/accounts/self [R]". It is not a good idea to set reverse proxy for a plugin, except for Gerrit authentication. How do you think?
