How do I enable the "largefiles" extension using the JavaHg Mercurial API?

I am using Mercurial 2.1.1 with the daily snapshot of JavaHg in a Grails 1.3.7 environment. I am trying to interact with a remote repository that has the largefiles extension enabled. I have created an hgrc file with the largefiles extension enabled and set the RepositoryConfiguration to point to it.

I have verified that the repository is pointing at the correct hgrc by putting a unique username in the hgrc file and verifying that the repository uses that username when doing a commit.

RepositoryConfiguration repoConfig = new RepositoryConfiguration()
repoConfig.setHgBin(CH.config.hgbin)
repoConfig.setHgrcPath(CH.config.hgrc)
Repository repo = Repository.clone(repoConfig, tempDir, remoteDir);

When I try to clone a repository with largefiles enabled, however, I get the following stacktrace:

java.lang.RuntimeException: abort: unknown repository format: requires features
                            'largefiles' (upgrade Mercurial)!

How do I enable the largefiles extension?

Solution

  • It should work to use a hgrc file that enables the largefiles extension as you have done. I have created a test case for JavaHg to test this.

    The Jenkins continuous integration has successfully executed the test with all Mecurial versions >=2.0.

    Maybe you could compare your code with the test case, and see what you do different?
