pip freeze

This will list all packages installed in the current environment. If

Kallithea isn't listed, activate the correct virtual environment.

See the appropriate installation page for details.

4. Install new version of Kallithea

-----------------------------------

Please refer to the instructions for the installation method you

originally used to install Kallithea.

If you originally installed using pip, it is as simple as::

    pip install --upgrade kallithea

If you originally installed from version control, it is as simple as::

    cd my-kallithea-clone

    hg pull -u

    pip install --upgrade -e .

    kallithea-cli front-end-build

5. Upgrade your configuration

-----------------------------

Run the following command to create a new configuration (``.ini``) file::

    kallithea-cli config-create new.ini

Then compare it with your old config file and see what changed.

.. note::

    Please always make sure your ``.ini`` files are up to date. Errors

    can often be caused by missing parameters added in new versions.

6. Upgrade your database

------------------------

.. note::

    If you are *downgrading* Kallithea, you should perform the database

    migration step *before* installing the older version. (That is,

    always perform migrations using the most recent of the two versions

    you're migrating between.)

First, run the following command to see your current database version::

Typical output will be something like "9358dc3d6828 (head)", which is

the current Alembic database "revision ID". Write down the entire output

for troubleshooting purposes.

The output will be empty if you're upgrading from Kallithea 0.3.x or

older. That's expected. If you get an error that the config file was not

found or has no ``[alembic]`` section, see the next section.

Next, if you are performing an *upgrade*: Run the following command to

upgrade your database to the current Kallithea version::

If you are performing a *downgrade*: Run the following command to

downgrade your database to the given version::

Alembic will show the necessary migrations (if any) as it executes them.

If no "ERROR" is displayed, the command was successful.

Should an error occur, the database may be "stranded" half-way

through the migration, and you should restore it from backup.

Enabling old Kallithea config files for Alembic use

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Kallithea configuration files created before the introduction of Alembic

(i.e. predating Kallithea 0.4) need to be updated for use with Alembic.

Without this, Alembic will fail with an error like this::

    FAILED: No config file 'my.ini' found, or file has no '[alembic]' section

If Alembic complains specifically about a missing ``alembic.ini``, it is

likely because you did not specify a config file using the ``-c`` option.

On the other hand, if the mentioned config file actually exists, you

need to append the following lines to it::

    [alembic]

    script_location = kallithea:alembic

Your config file should now work with Alembic.

7. Update Git repository hooks

------------------------------

It is possible that an upgrade involves changes to the Git hooks installed by

Kallithea. As these hooks are created inside the repositories on the server

filesystem, they are not updated automatically when upgrading Kallithea itself.

To update the hooks of your Git repositories:

* Go to *Admin > Settings > Remap and Rescan*

* Select the checkbox *Install Git hooks*

* Click the button *Rescan repositories*
