General Kallithea usage

Repository deletion

Currently when an admin or owner deletes a repository, Kallithea does not physically delete said repository from the filesystem, but instead renames it in a special way so that it is not possible to push, clone or access the repository.

There is a special command for cleaning up such archived repositories:

paster cleanup-repos --older-than=30d my.ini

This command scans for archived repositories that are older than 30 days, displays them, and asks if you want to delete them (unless given the --dont-ask flag). If you host a large amount of repositories with forks that are constantly being deleted, it is recommended that you run this command via crontab.

It is worth noting that even if someone is given administrative access to Kallithea and deletes a repository, you can easily restore such an action by renaming the repository directory, removing the rm__<date> prefix.

File view: follow current branch

In the file view, left and right arrows allow to jump to the previous and next revision. Depending on the way revisions were created in the repository, this could jump to a different branch. When the checkbox Follow current branch is checked, these arrows will only jump to revisions on the same branch as the currently visible revision. So for example, if someone is viewing files in the beta branch and marks the Follow current branch checkbox, the < and > arrows will only show revisions on the beta branch.

Changelog features

The core feature of a repository’s changelog page is to show the revisions in a repository. However, there are several other features available from the changelog.

Branch filter
By default, the changelog shows revisions from all branches in the repository. Use the branch filter to restrict to a given branch.
Viewing a changeset
A particular changeset can be opened by clicking on either the changeset hash or the commit message, or by ticking the checkbox and clicking the Show selected changeset button at the top.
Viewing all changes between two changesets

To get a list of all changesets between two selected changesets, along with the changes in each one of them, tick the checkboxes of the first and last changeset in the desired range and click the Show selected changesets button at the top. You can only show the range between the first and last checkbox (no cherry-picking).

From that page, you can proceed to viewing the overall delta between the selected changesets, by clicking the Compare revisions button.

Creating a pull request
You can create a new pull request for the changes of a particular changeset (and its ancestors) by selecting it and clicking the Open new pull request for selected changesets button.

Permanent repository URLs

Due to the complicated nature of repository grouping, URLs of repositories can often change. For example, a repository originally accessible from:

would get a new URL after moving it to test_group:

Such moving of a repository to a group can be an issue for build systems and other scripts where the repository paths are hardcoded. To mitigate this, Kallithea provides permanent URLs using the repository ID prefixed with an underscore. In all Kallithea URLs, for example those for the changelog and the file view, a repository name can be replaced by this _ID string. Since IDs are always the same, moving the repository to a different group will not affect such URLs.

In the example, the repository could also be accessible as:<ID>

The ID of a given repository can be shown from the repository Summary page, by selecting the Show by ID button next to Clone URL.

Email notifications

With email settings properly configured in the Kallithea configuration file, Kallithea will send emails on user registration and when errors occur.

Emails are also sent for comments on changesets. In this case, an email is sent to the committer of the changeset (if known to Kallithea), to all reviewers of the pull request (if applicable) and to all people mentioned in the comment using @mention notation.

Cloning remote repositories

Kallithea has the ability to clone repositories from given remote locations. Currently it supports the following options:

  • hg -> hg clone
  • svn -> hg clone
  • git -> git clone


svn -> hg cloning requires the hgsubversion library to be installed.

If you need to clone repositories that are protected via basic authentication, you can pass the credentials in the URL, e.g. Kallithea will then try to login and clone using the given credentials. Please note that the given credentials will be stored as plaintext inside the database. However, the authentication information will not be shown in the clone URL on the summary page.

Specific features configurable in the Admin settings

In general, the Admin settings should be self-explanatory and will not be described in more detail in this documentation. However, there are a few features that merit further explanation.

Repository extra fields

In the Visual tab, there is an option “Use repository extra fields”, which allows to set custom fields for each repository in the system.

Once enabled site-wide, the custom fields can be edited per-repository under Options | Settings | Extra Fields.

Example usage of such fields would be to define company-specific information into repositories, e.g., defining a repo_manager key that would give info about a manager of each repository. There’s no limit for adding custom fields. Newly created fields are accessible via the API.

Meta tagging

In the Visual tab, option “Stylify recognised meta tags” will cause Kallithea to turn certain text fragments in repository and repository group descriptions into colored tags. Currently recognised tags are:

[lang => lang]
[license => License]
[requires => Repo]
[recommends => Repo]
[see => URI]
