Upgrading Pagure

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

From 3.2 to 3.3

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

[SECURITY FIX]: The 3.3 release contains an important security fix.

If you are using the private project feature of pagure, the gitolite

configuration generated was still granting access to the private projects. This

made the private projects visible and accessible.

After updating to 3.3, ensure your gitolite configuration gets re-generated

(pagure-admin refresh-gitolite can help you with this).

The 3.3 release brings some adjustments to the database scheme.

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

From 3.1 to 3.2

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

While not being a bug fix, this release has no database schema changes.

However, this release breaks the plugin interface for auth introduced in 3.1 and

changed in 3.1. If you are using pagure-dist-git, make sure to upgrade to at

least 0.4. This interface will be considered stable in 3.4 and announced as

such.

From 3.0 to 3.1

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

While not being a bug fix, this release has no database schema changes.

However, this release breaks the plugin interface for auth introduced in 3.0. If

you are using pagure-dist-git, make sure to upgrade to at least 0.3.

From 2.15 to 3.0

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

The 3.0 version was released with some major re-architecturing. The interaction

with the backend git repo (being the main source repo or the tickets or requests

repos) are now done by a worker that is triggered via a message queue.

This communication is done using `celery <http: www.celeryproject.org="">`_ and</http:>

via one of the message queue celery supports (pagure currently defaulting to

`redis <https: redis.io="">`_.</https:>

So to get pagure 3.0 running, you will need to get your own message queue (such

as redis) up running and configured in pagure's configuration.

This major version bump has also been an opportunity to rename all the services

to use the same naming schema of pagure-<service>.</service>

The rename is as such:

+------------------+-----------------+

|  In 2.x          | From 3.0        |

+==================+=================+

| pagure-ci        | pagure-ci       |

+------------------+-----------------+

| ev-server        | pagure-ev       |

+------------------+-----------------+

| pagure-loadjson  | pagure-loadjson |

+------------------+-----------------+

| pagure-logcom    | pagure-logcom   |

+------------------+-----------------+

| milters          | pagure-milters  |

+------------------+-----------------+

| webhook-server   | pagure-webhook  |

+------------------+-----------------+

|                  | pagure-worker   |

+------------------+-----------------+

.. note:: This last service is the service mentioned above and it is part of

          pagure core, not optional unlike the other services in this table.

This release also introduces some new configuration keys:

- ``CELERY_CONFIG`` defaults to ``{}``

- ``ATTACHMENTS_FOLDER``, to be configured

- ``GITOLITE_BACKEND`` defaults to ``gitolite3``, deprecates ``GITOLITE_VERSION``

- ``EXTERNAL_COMMITTER`` defaults to ``{}``

- ``REQUIRED_GROUPS`` defaults to ``{}``

This version also introduces a few database changes, so you will need to update

the database schema using alembic: ``alembic upgrade head``.

From 2.14 to 2.15

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

The 2.15 release brings some adjustments to the database scheme.

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

From 2.13 to 2.14

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

The 2.14 release brings some adjustments to the database scheme.

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

From 2.12 to 2.13

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

The 2.13 release brings some adjustments to the database scheme.

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

From 2.11 to 2.12

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

From this release on, we will have alembic migration script for new table

creation, so there will no longer be a need to use ``createdb.py``

The 2.12 release brings some adjustments to the database scheme.

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

From 2.10 to 2.11

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

The 2.10 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``

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
