how to get the content of a commit?

[Robert Li]

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<String, Object> getItInParts(Repository repo, String commitId) {
    Commit c = commitService.getCommit(new CommitRequest.Builder(repo, commitId).build());
    PagedIterable<Change> changes = new PagedIterable(new PageProvider<Change>() {
        public Page<Change> 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.

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

[Robert Li]

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

[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 Li]

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

[Adam]

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