Installing support plugin has taken down SCM-Manager

As requested by @pfeuffer in my other Mercurial related thread I installed the support plugin into my SCM-Manager instance. During installation I selected the option to restart SCM-Manager, however the SCM-Manager service did not restart and now will not start.

If I look in the plugins folder I see the scm-support_plugin.smp file was downloaded but not decompressed as there is no scm-support_plugin folder.

SCM Manager 2.24 (fresh install as of a few days ago, no other plugins but standard)
Windows 2019
SCM-Manager service is running with a specific Windows user account, not LocalSystem. (Switching back to LocalSystem now doesn’t help).

My first priority is to get this server back up and running. I’ve tried to find a way to reverse the support plugin installation manually but i can’t find any reference to it in the configuration files. Please advise how this can be achieved as soon as possible.

Your forum won’t accept a zip file so I’ve quoted the relevant sections of the logs rather than uploading the whole thing.

Hey @lachlang,

Not sure what happened there yet, but try to delete the .smp file and restart your server. We will look into it and try to figure out how this could happen.

Just by looking at your stacktrace, i’m not sure the support plugin could have done this.

Hope this helps.
Eduard

Sorry I should have mentioned I already tried removing the .smp file and restarting the machine. I also tried unpacking the .smp file and putting it in place but that did nothing either.

This is a fresh install of SCM-Manager from just a few days ago. This is all that has been done with it:

  • SCM-Manager is on D:\SCM-Manager
  • The home directory has been set to D:\SCM-Manager-Data
  • Mercurial has been configured to use the hg.exe of a locally installed TortoiseHg instance.
  • It is running on port 8080 but is behind an IIS reverse proxy that is forwarding the SSL requests/responses.
  • The service is configured to run using a local Windows user via the services control panel. The Windows user does not have administrative rights but does have full access to the D drive.
  • No plugins had been installed until the support plugin this morning.

The server was installed about 3 days ago and has been running fine. Yesterday we configured the IIS reverse proxy but we didn’t need to change the SCM-Manager configuration at all to get that running. Looking at the logs the server was restarted several times yesterday as we wrestled with IIS but each time SCM-Server came up fine. This morning I installed the support plugin as requested and SCM-Server has not run successfully since.

I’ll zip up both D drive folders in their current state for later inspection but right now I have to get this server back up and running. If you have some advice on how to do that I’d appreciate it, otherwise I’ll probably have to rebuild the SCM-Server installation.

We’ve managed to get it going again. Turns out it was our fault but you’ll probably want to make sure nobody else falls into this trap.

My server guy just arrived and said he did actually make a configuration change to SCM-Server yesterday while he was trying to get the IIS reverse proxy to work. It was to the \conf\server-config.xml file he added

      <!-- for mod_proxy -->
      <Set name="forwarded">true</Set>

which he found on the documentation for reverse proxying for an earlier SCM-Manager version.

We’ve removed those lines and it started fine, plus our reverse proxying is still working too. I hope you can use this info to stop others from making this same mistake.

Hi, we added a header with a warning to sites that are outdated a few days ago. Maybe this wasn’t in place when your colleague found it. Currently we are struggling with Google a bit, so that it shows the latest pages, but that isn’t as straight forward as we would have liked. Thanks for the hint, though.

It was only yesterday so it would have been there. I think he was grasping at straws and so decided to try it out, perhaps thinking it had been accidentally omitted from the latest version of the docs.

I don’t know exactly what adding that parameter to the server-config.xml file does but I would imagine that a bunch of people who are migrating from older versions will have it set in there. Perhaps the software should either ignore or remove it when it encounters that setting.
