how to get the content of a commit?

Robert Li3

I'm trying to enforce a script onto the contents of a commit, but I've yet to figure out how to get the actual commit contents. I see examples on how to obtain the name, JIRA tickets, and other stuff but how do I get the commit that is seen in git on bitbucket?

Thanks

You have a couple options. If you really want the output of git log -p, you can run it directly:

MyThing(GitCommandBuilderFactory builderFactory) {
    this.builderFactory = builderFactory;
}
public String getItAll(Repository repo, String commitId) {
    return builderFactory.builder(repo).command("log").argument("-p").argument("-n").argument("1").argument(commitId).call(new StringOutputHandler());
}

Or you can run a few commands to get different parts into their respective business objects:

MyThing(CommitService commitService) {
    this.commitService = commitService;
}
public Map&lt;String, Object&gt; getItInParts(Repository repo, String commitId) {
    Commit c = commitService.getCommit(new CommitRequest.Builder(repo, commitId).build());
    PagedIterable&lt;Change&gt; changes = new PagedIterable(new PageProvider&lt;Change&gt;() {
        public Page&lt;Change&gt; get(PageRequest pageRequest) {
            return commitService.getChanges(new ChangesRequest.Builder(repo, commitId).build(), pageRequest);
        }
    }, 25);
    commitService.streamDiff(new DiffRequest.Builder(repo, commitId).build(), new DiffContentCallback() {
        // ... implement methods that are called as the diff is streamed.
        // Note that the content will be capped after 10k lines across the change. You can get diffs of individual paths if you need to.
    });    
}

Note that the changes and the diff might be redundant if you don't actually need all the information about the commit.

I haven't tested either of those snippets, so they probably don't actually work, but that's the gist of how to get the information - a good starting point at least.

By "content" do you mean the commit message, or the list of files changed, or the diffs of those files, or something else?

Robert Li3

the original content of the commit, as in everything that was seen in git for the commit

Adam

That's still not really clarifying it for me. What does "seen in git" mean? Do you want the output of a particular git command?

Robert Li3

I want the output of git log -p or git show basically

PagedIterable seems to be gone in Bitbucket 6.x, is there any alternative?
