Upgrading Pagure

================

From 2.9 to 2.10

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

The 2.10 releases brings some little changes to the database scheme.

Therefore when upgrading to 2.10, you will have to:

* Update the database schame using alembic: ``alembic upgrade head``

From 2.8 to 2.9

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

The 2.9 releases brings some adjustments to the database scheme.

* Create the new DB tables and the new status field using the ``createdb.py``

    script.

* Update the database schame using alembic: ``alembic upgrade head``

If you are interested in loading your local data into the ``pagure_logs`` table

that this new release adds (data which is then displayed in the calendar heatmap

on the user's page), you can find two utility scripts in

https://pagure.io/pagure-utility that will help you to do that. They are:

* fill_logs_from_db - Based on the data present in the database, this script

  fills the ``pagure_logs`` table (this will add: new ticket, new comment, new

  PR, closing a PR or a ticket and so on).

* fill_logs_from_gits - By going through all the git repo hosted in your pagure

  instance, it will log who did what when.

From 2.7 to 2.8

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

2.8 brings a little change to the database scheme.

Therefore when upgrading to from 2.7 to 2.8, you will have to:

* Update the database schame using alembic: ``alembic upgrade head``

From 2.6 to 2.7

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

2.7 adds new tables as well as changes some of the existing ones.

Therefore when upgrading to 2.7, you will have to:

* Create the new DB tables and the new status field using the ``createdb.py``

  script.

* Update the database schame using alembic, one of the upgrade will require

  access to pagure's configuration file, which should thus be passed onto the

  command via an environment variable:

  ``PAGURE_CONFIG=/path/to/pagure.cf alembic upgrade head``

This release also brings a new configuration key:

* ``INSTANCE_NAME`` used in the welcome screen shown upon first login (only with

  FAS and OpenID auth) to describe the instance

The API has also been upgraded to a version ``0.8`` due to the changes (backward

compatible) made to support the introduction of `close_status` to issues.

From 2.5 to 2.6

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

2.6 brings quite a few changes and some of them impacting the database scheme.

Therefore when upgrading from 2.4 to 2.6, you will have to:

* Update the database schame using alembic: ``alembic upgrade head``

From 2.4 to 2.5

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

2.5 brings quite a few changes and some of them impacting the database scheme.

Therefore when upgrading from 2.4 to 2.5, you will have to:

* Update the database schame using alembic: ``alembic upgrade head``

From 2.3 to 2.4

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

2.4 brings quite a few changes and some of them impacting the database scheme.

Therefore when upgrading from 2.3.x to 2.4, you will have to:

* Update the database schame using alembic: ``alembic upgrade head``

This update also brings some new configuration keys:

* ``VIRUS_SCAN_ATTACHMENTS`` allows turning on or off checking attachments for

  virus using clamav. This requires pyclamd but is entirely optional (and off by

  default)

* ``PAGURE_CI_SERVICES`` allows specifying with which CI (Continuous

  Integration) services this pagure instance can integrate with. Currently, only

  `Jenkins` is supported, but this configuration key defaults to ``None``.

From 2.2 to 2.3

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

2.3 brings a few changes impacting the database scheme, including a new

`duplicate` status for tickets, a feature allowing one to `watch` or

`unwatch` a project and notifications on tickets as exist on pull-requests.

Therefore, when upgrading from 2.2.x to 2.3, you will have to :

* Create the new DB tables and the new status field using the ``createdb.py`` script.

* Update the database schame using alembic: ``alembic upgrade head``

This update also brings a new configuration key:

* ``PAGURE_ADMIN_USERS`` allows to mark some users as instance-wide admins, giving

  them full access to every projects, private or not. This feature can then be

  used as a way to clean spams.

* ``SMTP_PORT`` allows to specify the port to use when contacting the SMTP

  server

* ``SMTP_SSL`` allows to specify whether to use SSL when contacting the SMTP

  server

* ``SMTP_USERNAME`` and ``SMTP_PASSWORD`` if provided together allow to contact

  an SMTP requiring authentication.

In this update is also added the script ``api_key_expire_mail.py`` meant to be

run by a daily cron job and warning users when their API token is nearing its

expiration date.

2.2.2

-----

Release 2.2.2 contains an important security fix, blocking a source of XSS

attack.

From 2.1 to 2.2

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

2.2 brings a number of bug fixes and a few improvements.

One of the major changes impacts the databases where we must change some of the

table so that the foreign key cascade on delete (fixes deleting a project when a

few plugins were activated).

When upgrading for 2.1 to 2.2 all you will have to do is:

* Update the database scheme using alembic: ``alembic upgrade head``

.. note:: If you run another database system than PostgreSQL the alembic

  revision ``317a285e04a8_delete_hooks.py`` will require adjustment as the

  foreign key constraints are named and the names are driver dependant.

From 2.0 to 2.1

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

2.1 brings its usual flow of improvements and bug fixes.

When upgrading from 2.0.x to 2.1 all you will have to:

* Update the database schame using alembic: ``alembic upgrade head``

From 1.x to 2.0

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

As the version change indicates, 2.0 brings quite a number of changes,

including some that are not backward compatible.

When upgrading to 2.0 you will have to:

* Update the database schema using alembic: ``alembic upgrade head``

* Create the new DB tables so that the new plugins work using the

  ``createdb.py`` script

* Move the forks git repo

Forked git repos are now located under the same folder as the regular git

repos, just under a ``forks/`` subfolder.

So the structure changes from: ::

    repos/

    ├── foo.git

    └── bar.git

    forks/

    ├── patrick/

    │   ├── test.git

    │   └── ipsilon.git

    └── pingou/

        ├── foo.git

        └── bar.git

to: ::

    repos/

    ├── foo.git

    ├── bar.git

    └── forks/

        ├── patrick/

        │   ├── test.git

        │   └── ipsilon.git

        └── pingou/

            ├── foo.git

            └── bar.git

So the entire ``forks`` folder is moved under the ``repos`` folder where

the other repositories are, containing the sources of the projects.

Git repos for ``tickets``, ``requests`` and ``docs`` will be trickier to

move as the structure changes from: ::

    tickets/

    ├── foo.git

    ├── bar.git

    ├── patrick/

    │   ├── test.git

    │   └── ipsilon.git

    └── pingou/

        ├── foo.git

        └── bar.git

to: ::

    tickets/

    ├── foo.git

    ├── bar.git

    └── forks/

        ├── patrick/

        │   ├── test.git

        │   └── ipsilon.git

        └── pingou/

            ├── foo.git

            └── bar.git

Same for the ``requests`` and the ``docs`` git repos.

As you can see in the ``tickets``, ``requests`` and ``docs`` folders there

are two types of folders, git repos which are folder with a name ending

with ``.git``, and folder corresponding to usernames. These last ones are

the ones to be moved into a subfolder ``forks/``.

This can be done using something like: ::

    mkdir forks

    for i in `ls -1 |grep -v '\.git'`; do mv $i forks/; done

* Re-generate the gitolite configuration.

This can be done via the ``Re-generate gitolite ACLs file`` button in the

admin page.

* Keep URLs backward compatible

The support of pseudo-namespace in pagure 2.0 has required some changes

to the URL schema:

https://pagure.io/pagure/053d8cc95fcd50c23a8b0a7f70e55f8d1cc7aebb

became:

https://pagure.io/pagure/c/053d8cc95fcd50c23a8b0a7f70e55f8d1cc7aebb

(Note the added /c/ in it)

We introduced a backward compatibility fix for this.

This fix is however *disabled* by default so if you wish to keep the URLs

valid, you will need to adjust you configuration file to include: ::

    OLD_VIEW_COMMIT_ENABLED = True
