I'm getting a "hostname could not be parsed" error when trying to open a newly created repository. This is a new installation, no errors during setup. I have created a new project and repository.

I'm accessing my site internally, via http://servername:8050. In Settings > General, I have the Site URL as http://servername:8050

Suggestions where I went wrong?

    Charles,

    Could you provide a stacktrace for this error (or all the text on a yellowish error page)?

    Also, what are the names/slugs of your project and repository?

    Project Name: Test Project
    Project Slug: testproject
    Repository Name: MyTest

    Same error using an imported (copied) repository named SC Test.

    URLs:
    http://servername:8050/projects/testproject/repositories/mytest/source/files
    http://servername:8050/projects/testproject/repositories/sc%20test/source/files

    If you need to know my server name, let me know. I'd prefer to send that
    privately.

    Thanks for your quick reply. I'm excited about HgLab, having suffered
    through installing Mercurial to work in IIS.

    I tried setting HgLab to a new, empty repository folder and got the error below.

    When I first set up the site, I chose a folder that had my existing repositories in it. When I saved, I was prompted to upgrade (though the version numbers were the same). In that original folder, the structure ended up like this:
    repo
    |_data
      |_repositories
        |_master
          |_testproject
             |_MyTest
             |_SC Test

    The new folder failed to update with a permissions error. I think I fixed the permissions, but keep getting prompted to upgrade. I can't even log off.

    Charles,

    What is the login you're using to sign in to HgLab?

    As for "Upgrading from 0.3.10 to 0.3.10" - this is "by design", albeit not particularly friendly "design". You can try running these commands in a Privileged Command Prompt:

    icacls {hglab-home-directory} /t /remove:g iis_iusrs
    icacls {hglab-home-directory} /grant iis_iusrs:(OI)(CI)(F)
    

    and then click "Upgrade" and wait for HgLab to complete. If it doesn't complete in a reasonable time, create a file named .hglab.version and containing 0.3.10 in your {hglab-home-directory}.

    >What is the login...
    I'm using my email address as my login.

    Running the icals commands took care of the permissions issue, and the site "upgraded" quickly.

    To test with the new, empty repository folder, I deleted the existing repository/project records in the database.

    Given your question, I also did some testing. Apparently, if Login is an email address, the error occurs. (Or maybe, if Login is same as email.) If login isn't an email, I can log in and view repositories just fine.

    A few initial thoughts, besides the bug(?) of the login.

    1. The documentation isn't exactly accurate when it comes to the folder structure.
    2. Adding existing repositories isn't as easy as copying the folder. It also has to be added via Add Repository.
    3. I can change the home directory, but there's not synchronization with the database.

    The sync issue is probably the biggest. It's going to be hard to make that work unless the site:
    1. Joins home-directory to project or repository.
    2. Has a "resync" feature or utility that looks for changes between the database and the folders.

    I wonder if maintaining project/repository data is needed? The regular Mercurial server can be configured to allow a nested folder structure, which is something I was using. Would you be able to dynamically read the folders, but still maintain your other features (security, pull requests, etc.)?

    As much as I like the site, it may not meet my needs. If I have the time, I may pull and look at your source and see whether I have any useful contribution to make.

    Critique aside, I love the work you're doing. Mercurial in IIS just shouldn't be as hard as it is, and you're making it better.

    Charles,

    There's a bug in 0.3.10 when using an email address as your login triggers an error on certain pages. That one is fixed in a newer version which is long due to be released.

    As for the home directory, that's a tough one (well, except documentation, which is something I've been neglecting for a while). It is generally not encouraged to tinker with directly, since it's supposed to be managed by HgLab itself. True, adding existing repositories can be a bit cumbersome, but streamlining this process is on my todo list. The "official" way is to add an empty repository via web interface and then push to it.

    Having a "Resync Repositories" feature (automatic or manual) is nice, but it would imply encouraging direct access to Home Directory. That's bothersome since there will be a lot more stuff stored there (like Mercurial-backed wikis, forks, attachment blobs, etc) and there's a non-zero chance of screwing things up in the process.

    Thanks for offering contributions, but HgLab is not exactly open-source (HgSharp is) and I'm planning on building a business around it.

    Oh, and thanks for the kind words!

    I'll look forward to the next version. I'm definitely not finished
    evaluating HgLab. Best wishes on your business.

    Regarding changing home directories, from an installer/admin point of view
    it would help to get a warning or other help that says something like,
    "Changing your home directory is intended for situations where you're
    moving your repositories...."

    Also, while "auto sync" doesn't sound like a good fit, you could have a
    feature for new installations where the site reads a copied repository
    folder and creates projects/repositories from that. It would assume one
    level of project-repository. Unless, of course, you build support for
    nested projects, which would be awesome.

    I see the above as an attractive installation/configuration option for
    people who want to switch to HgLab from an existing Mercurial installation.

    Thanks, again, for all your help.
