Init failure on Gerrit plugin

Open orgads opened this issue 3 years ago • 19 comments

I'm trying to revive the gitblit plugin for Gerrit 3.5. I built it successfully, but when I'm trying to load it, I get the following exception:

com.google.gerrit.server.plugins.PluginInstallException: Unable to provision, see the following errors:

I tried replacing NotificationManager contents with NoopNotificationManager, and it worked, so I guess it's something in the class implementation.

What Java version is this running on? This sounds like a problem that comes up with moving to Java 9 or higher. From Java 9 on some classes were not part of the JVE anymore and need to be included as an explicit dependency. That is why the dependency to com.sun.activation:javax.activation:1.2.0 was added. You may have to make sure that is present in your build.

Java 11. I have this dependency.

orgads avatar Mar 18 '22 12:03 orgads

ping?

orgads avatar Apr 04 '22 19:04 orgads

I would love to help, but I don't build the plugin or run a Gerrit instance. So I don't know how else to help. From experience and from the error message, it is a missing dependency that is not present in your server's runtime class path. I cannot think of anything else but to make sure that the java.activation JAR is preset in the class path that is used for the server.

flaix avatar Apr 07 '22 09:04 flaix

Were you able to get more debug information or other information? Like check if the JAR is present at runtime?

flaix avatar Apr 27 '22 10:04 flaix

I have a simple way to reproduce, if it helps. This is a jar I built with the change linked above, and latest gerrit 3.5: gitblit.zip.

Rename it to jar, then run:

docker run --rm -ti -p 8080:8080 -p 29418:29418 -v $PWD/gitblit.jar:/var/gerrit/plugins/gitblit.jar gerritcodereview/gerrit:3.5.1

This is the output I'm getting:

How did you manage to build it? I tried to build the plugin, but it complains about downloading wicket-extensions from maven central. I cannot download the zip file you attached, so I tried to build it myself. What changed so that it can be built from the stock JAR, compared to previously?

Edit: Apparently it just needs to be executed a few times to correct itself. But now I am stuck at the build complaining about jgit

Do you have all the submodules checked out? Run git submodule update --init and retry building.

I take you build this on Linux? Because I am getting nowhere with macOS.

flaix avatar Nov 19 '22 18:11 flaix

Well, as expected the resulting gitblit.jar plugin does not contain the javax.activation classes. You said you have this dependency? I got your branch but did not find it in the external_plugin_deps.bzl file.

Anyhow, if I add below patch, it builds and runs in Gerrit. Well, it starts. I have no idea how to see if it actually works then. You may want to apply the patch and try it in Gerrit.

While we are at it, is there a way for Gitblit to know that it runs as a Gerrit plugin?

flaix avatar Nov 20 '22 13:11 flaix

@flaix Thanks for the hint. Looks better, but it now fails with another error:

I take you build this on Linux? Because I am getting nowhere with macOS.

In order to build, you need to replace external_plugin_deps.bzl in plugins with the one in gitblit. It's in the README.

cd plugins
ln -sf gitblit/external_plugin_deps.bzl .
cd ..
bazel build plugins/gitblit

orgads avatar Nov 20 '22 13:11 orgads

In order to build, you need to replace external_plugin_deps.bzl in plugins with the one in gitblit. It's in the README.

Yeah, I did that according to the Readme, but I could not get it compiled on macOS. The build didn't like the clang C compiler. So I switched to a Linux VM.

flaix avatar Nov 20 '22 16:11 flaix

I guess now come the hard problems as we have reached the realms of class loaders.

How can one put some repositories in the container to see that?

flaix avatar Nov 20 '22 16:11 flaix

Here is a new build for 3.7: gitblit.zip

Rename gitblit.war, use this docker-compose.yml and run docker-compose up:

version: '3'

services:
  gerrit:
    image: gerritcodereview/gerrit:3.7.0
    ports:
      - "8070:8080"
    volumes:
      - ./gitblit.jar:/var/gerrit/plugins/gitblit.jar
      - gerrit-etc:/var/gerrit/etc
      - gerrit-git:/var/gerrit/git
      - gerrit-db:/var/gerrit/db
      - gerrit-index:/var/gerrit/index
      - gerrit-cache:/var/gerrit/cache
    environment:
      - CANONICAL_WEB_URL=http://localhost:8070

volumes:
  gerrit-etc:
  gerrit-git:
  gerrit-db:
  gerrit-index:
  gerrit-cache:

There are 2 repositories that are created automatically, All-Projects and All-Users.

You can reproduce the issue just by opening http://your-server:8080/plugins/gitblit/repositories/

I pushed my latest changes here: https://github.com/orgads/gerrit-gitblit-plugin, on branch master.

Switched back to building gitblit from source, and using MAVEN_LOCAL.

orgads avatar Nov 20 '22 17:11 orgads

I have to say I'm really confused about https://github.com/orgads/gerrit-gitblit-plugin/commit/d0357a6e15267a687f791149d0d94539fbf56cdb#diff-7065071696a179130d4c9022da41d3b5ca979899627876119e6c88e2573a6a25R140. How come 2 calls to the same function (getAttribute) return different types? The first call for gerrit-username returns Optional<String>, but the second call for gerrit-token returns String. If I change the casts, I get an error (cannot cast Optional to String, or String to Optional). And it's not even consistent. On my system, both return String.

orgads avatar Nov 20 '22 19:11 orgads

@lucamilanesio @paladox @davido Maybe you'll have ideas regarding https://github.com/gitblit/gitblit/issues/1413#issuecomment-1321131828?

orgads avatar Nov 21 '22 06:11 orgads

When I run with your docker compose file, I don't get the error about class loaders you pasted. But I do get the class cast exception. This seems something in the plugin, I am guessing. It might depend on where the attributes were set. I don't know if that happens in Gerrit or the plugin. The getAttribute method returns an Object, since any type can be attached to the session as an Object. So type safe handling would probably be to check for the type with an instanceof and act accordingly. But I don't really know about how Gerrit works there.
