Errors while using Git API extension

bartkummel · February 19, 2019, 8:32am

Hi,

I’m trying to use the Git API extension. I have some GitHub wikis that I want to move to XWiki. First I tried using the Github API, but Github wikis are not reachable via the API. But Github wikis can be used as “normal” Git repositories. So I thought I could use the Git API extension to clone those wiki repos and then create Markdown XWiki pages for each Markdown file in the wiki repository.

So I thought it would be good to get started with one of the examples from the Github API extension documentation page. I skipped the Velocity examples, as I think I’ll be needing better scripting facilities, so I started with the Groovy examples.

While running Example 3, I get the following error:

Failed to execute the [groovy] macro. Cause: [No signature of method: org.gitective.core.CommitFinder.setMatcher() is applicable for argument types: (org.gitective.core.filter.commit.AndCommitFilter) values: [AndCommitFilter]]. Click on this message for details.

Here’s the full stack trace:

Has anyone an idea how to fix this? Or is this a bug in the Git API module? Hope someone can help… If someone has an idea for another approach to import my Github wikis, those are more than welcome as well!

Best regards,

The reason is because the gitective dependency has been upgraded in GIT-4 (see https://extensions.xwiki.org/xwiki/bin/view/Extension/Git%20Module#Hv9.7) and it broke backward compatibility (because of JGit 2.0), see https://github.com/kevinsawicki/gitective/commit/d12ac46ec2f072918c32328b52489d34bffb2c3e#diff-8a2525c400bd50a39547d567fb17a089

The XWiki Git API module is working fine. It’s just the example that needs to be modified to use the new APIs.

bartkummel · February 19, 2019, 9:38am

So the Git API actually exposes the Gitective API? I think it would be a good idea to mention that in the Git API module’s documentation. Unfortunately the Gitective documentation is pretty much non-existing, so that wouldn’t be very helpful…

On a side note: the README of Gitective states that it is no longer being maintained. The README itself seems outdated, since the example there also uses the setMatcher() method that’s no longer there.

Anyway, thanks for pointing me to that diff. It shows me that I should replace setMatcher() by setFilter().

vmassol · February 19, 2019, 9:39am

That seems like a very good idea

We would love to see a GitHub to XWiki importer in the future

BTW I’ve just added it as a GSOC idea at https://dev.xwiki.org/xwiki/bin/view/GoogleSummerOfCode/GitHubImporter but feel free to implement it if you’re interested! We can guide you if you’re interested.

vmassol · February 19, 2019, 9:44am

It’s already mentioned with:

This module uses JGit and Gitective to provide the following APIs which can be used directly from within Script macros to easily perform Git actions:

I’ve added the imports in the Script Service API that is documented, so that you can see the objects returned.

I find it quite ok, the only problem is that it’s also out of date WRT setMatcher(), see https://github.com/fabric8io/gitective

Yes and that’s why we’re using a maintained fork of Gitective: https://github.com/fabric8io/gitective

vmassol · February 19, 2019, 9:45am

If I get the time I’ll try to find how to rewrite the examples. Now, if you find how to rewrite them yourself, it would be great if you could edit the doc and fix it! Thx

bartkummel · February 19, 2019, 9:59am

Sorry, I might have drawn my conclusions a bit too fast. Good to know that you’re using a maintained fork, a pity that even in the fork the documentation is outdated.

Sure, I want to update the docs if I figure out how to do it! Unfortunately I now stumble upon the next hurdle:

Failed to execute the [groovy] macro. Cause: [Checkout conflict with files: pom.xml.... [huge list of files]

Any idea how I can fix this?

bartkummel · February 19, 2019, 10:03am

I don’t think I’ll have the time to write a full blown re-usable importer. However, I will share the code I write, so that it can be used to build upon by someone who does have the time.

vmassol · February 19, 2019, 10:56am

I’ve now updated the docs and tested all examples and they all work for me, see:
https://extensions.xwiki.org/xwiki/bin/view/Extension/Git%20Module?viewer=changes&rev1=23.1&rev2=23.2

vmassol · February 19, 2019, 10:56am

Seems you’ve had some problems with the git clone. You could remove the git directory from your xwiki permanent directory for ex.

bartkummel · February 19, 2019, 11:07am

I use an xwiki.com hosted XWiki. I think I don’t have access to that directory…

vmassol · February 19, 2019, 11:10am

You do, using Groovy

But be careful you can break your whole wiki with Groovy!

bartkummel · February 20, 2019, 12:48pm

Thanks for the hint. I created this script to remove all directories created by one of the examples:

import org.apache.commons.io.*
import org.eclipse.jgit.api.*
import org.eclipse.jgit.lib.*
import org.eclipse.jgit.revwalk.*
import org.eclipse.jgit.storage.file.*
import org.gitective.core.*
import org.gitective.core.filter.commit.*
import groovy.json.*

def service = services.get("git") 

// Get all XWiki organization repositories from GitHub
def url = "https://api.github.com/users/xwiki/repos".toURL().text
def root = new JsonSlurper().parseText(url)

// For each repo, clone it locally to get stats for it
def repos = []
println "== Github Repos"
println "|=name|=url"
root.each() { repoXML ->
  println "|${repoXML.name}|${repoXML.git_url}"
  def repo = service.getRepository(repoXML.git_url, repoXML.name)
  //new Git(repo).pull().call()
  repos.add(repo)
}

println "== Repo worktrees"
println "|=working tree|=deleted"
repos.each { repo ->
  result = repo.workTree.deleteDir()
  println "|${repo.workTree}|${result}"
}

Now I’m ready to work on my importer script. To be continued…

BTW: above script might be useful as extra example, since it may help others troubleshooting. However, I was not able to edit the Git API wiki page…

bartkummel · March 5, 2019, 2:17pm

I used the JGit API to create a script to import Github wikis: https://snippets.xwiki.org/xwiki/bin/view/Extension/Github%20wiki%20import/

vmassol · March 5, 2019, 2:47pm

@bartkummel This is awesome, well done!

I’ve updated https://dev.xwiki.org/xwiki/bin/view/GoogleSummerOfCode/GitHubImporter with a link to your snippet. Will be very useful for any GSOC student taking up this project. So you have done the POC. The next step is to transform that into Java Component implementing the Filter Appication.

Thanks
