2.8 brings a little change to the database scheme.
Pierre-Yves Chibon f8b181
Pierre-Yves Chibon f8b181
Therefore when upgrading to from 2.7 to 2.8, you will have to:
Pierre-Yves Chibon f8b181
Pierre-Yves Chibon f8b181

Pierre-Yves Chibon 87f714
2.7 adds new tables as well as changes some of the existing ones.
Pierre-Yves Chibon 87f714
Pierre-Yves Chibon 87f714
Therefore when upgrading to 2.7, you will have to:
Pierre-Yves Chibon 87f714
Pierre-Yves Chibon 87f714
* Create the new DB tables and the new status field using the ``createdb.py``
Pierre-Yves Chibon 87f714
  script.
Pierre-Yves Chibon 87f714
Pierre-Yves Chibon 87f714
* Update the database schame using alembic, one of the upgrade will require
Pierre-Yves Chibon 87f714
  access to pagure's configuration file, which should thus be passed onto the
Pierre-Yves Chibon 87f714
  command via an environment variable:
Pierre-Yves Chibon 87f714
  ``PAGURE_CONFIG=/path/to/pagure.cf alembic upgrade head``
Pierre-Yves Chibon 87f714
Pierre-Yves Chibon 87f714
Pierre-Yves Chibon 87f714
This release also brings a new configuration key:
Pierre-Yves Chibon 87f714
Pierre-Yves Chibon 87f714
* ``INSTANCE_NAME`` used in the welcome screen shown upon first login (only with
Pierre-Yves Chibon 87f714
  FAS and OpenID auth) to describe the instance
Pierre-Yves Chibon 87f714
Pierre-Yves Chibon 87f714
Pierre-Yves Chibon 87f714
The API has also been upgraded to a version ``0.8`` due to the changes (backward
Pierre-Yves Chibon 87f714
compatible) made to support the introduction of `close_status` to issues.

  virus using clamav. This requires pyclamd but is entirely optional (and off by
Pierre-Yves Chibon 4cd012
  default)
Pierre-Yves Chibon 4cd012
* ``PAGURE_CI_SERVICES`` allows specifying with which CI (Continuous
Pierre-Yves Chibon 4cd012
  Integration) services this pagure instance can integrate with. Currently, only
Pierre-Yves Chibon 4cd012
  `Jenkins` is supported, but this configuration key defaults to ``None``.

Pierre-Yves Chibon 4912c9
Pierre-Yves Chibon 4912c9
2.3 brings a few changes impacting the database scheme, including a new
Pierre-Yves Chibon 4912c9
`duplicate` status for tickets, a feature allowing one to `watch` or
Pierre-Yves Chibon 4912c9
`unwatch` a project and notifications on tickets as exist on pull-requests.
Pierre-Yves Chibon 4912c9
Pierre-Yves Chibon 4912c9
Therefore, when upgrading from 2.2.x to 2.3, you will have to :
Pierre-Yves Chibon 4912c9
Pierre-Yves Chibon 4912c9
* Create the new DB tables and the new status field using the ``createdb.py`` script.
Pierre-Yves Chibon 4912c9

Pierre-Yves Chibon 4912c9
Pierre-Yves Chibon 4912c9
This update also brings a new configuration key:
Pierre-Yves Chibon 4912c9
Pierre-Yves Chibon 4912c9
* ``PAGURE_ADMIN_USERS`` allows to mark some users as instance-wide admins, giving
Pierre-Yves Chibon 4912c9
  them full access to every projects, private or not. This feature can then be
Pierre-Yves Chibon 4912c9
  used as a way to clean spams.
Pierre-Yves Chibon 4912c9
* ``SMTP_PORT`` allows to specify the port to use when contacting the SMTP
Pierre-Yves Chibon 4912c9
  server
Pierre-Yves Chibon 4912c9

  an SMTP requiring authentication.
Pierre-Yves Chibon 4912c9
Pierre-Yves Chibon 4912c9
In this update is also added the script ``api_key_expire_mail.py`` meant to be
Pierre-Yves Chibon 4912c9
run by a daily cron job and warning users when their API token is nearing its
Pierre-Yves Chibon 4912c9
expiration date.

Pierre-Yves Chibon 4cc330
From 2.1 to 2.2
Pierre-Yves Chibon 4cc330
---------------
Pierre-Yves Chibon 4cc330
Pierre-Yves Chibon 4cc330
2.2 brings a number of bug fixes and a few improvements.
Pierre-Yves Chibon 4cc330
Pierre-Yves Chibon 4cc330
One of the major changes impacts the databases where we must change some of the
Pierre-Yves Chibon 4cc330
table so that the foreign key cascade on delete (fixes deleting a project when a
Pierre-Yves Chibon 4cc330
few plugins were activated).
Pierre-Yves Chibon 4cc330
Pierre-Yves Chibon 4cc330
When upgrading for 2.1 to 2.2 all you will have to do is:
Pierre-Yves Chibon 4cc330
Pierre-Yves Chibon 4cc330
* Update the database scheme using alembic: ``alembic upgrade head``
Pierre-Yves Chibon 4cc330
Pierre-Yves Chibon 4cc330
.. note:: If you run another database system than PostgreSQL the alembic
Pierre-Yves Chibon 4cc330
  revision ``317a285e04a8_delete_hooks.py`` will require adjustment as the
Pierre-Yves Chibon 4cc330
  foreign key constraints are named and the names are driver dependant.

Pierre-Yves Chibon b945b9
From 2.0 to 2.1
Pierre-Yves Chibon b945b9
---------------
Pierre-Yves Chibon b945b9
Pierre-Yves Chibon b945b9
2.1 brings its usual flow of improvements and bug fixes.
Pierre-Yves Chibon b945b9
Pierre-Yves Chibon b945b9
When upgrading from 2.0.x to 2.1 all you will have to:
Pierre-Yves Chibon b945b9
Pierre-Yves Chibon b945b9
* Update the database schame using alembic: ``alembic upgrade head``
Pierre-Yves Chibon b945b9
Pierre-Yves Chibon b945b9
Pierre-Yves Chibon b945b9
Pierre-Yves Chibon 24cf2b
From 1.x to 2.0
Pierre-Yves Chibon 24cf2b
---------------
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon 24cf2b
As the version change indicates, 2.0 brings quite a number of changes,
Pierre-Yves Chibon 24cf2b
including some that are not backward compatible.
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon 24cf2b
When upgrading to 2.0 you will have to:
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon 24cf2b
* Update the database schema using alembic: ``alembic upgrade head``
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon b01b78
* Create the new DB tables so that the new plugins work using the
Pierre-Yves Chibon b01b78
  ``createdb.py`` script
Pierre-Yves Chibon b01b78
Pierre-Yves Chibon 24cf2b
* Move the forks git repo
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon 24cf2b
Forked git repos are now located under the same folder as the regular git
Pierre-Yves Chibon 24cf2b
repos, just under a ``forks/`` subfolder.
Pierre-Yves Chibon 24cf2b
So the structure changes from: ::
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon 24cf2b
    repos/
Pierre-Yves Chibon 24cf2b
    ├── foo.git
Pierre-Yves Chibon 24cf2b
    └── bar.git
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon 24cf2b
    forks/
Pierre-Yves Chibon a591b5
    ├── patrick/
Pierre-Yves Chibon a591b5
    │   ├── test.git
Pierre-Yves Chibon a591b5
    │   └── ipsilon.git
Pierre-Yves Chibon a591b5
    └── pingou/
Pierre-Yves Chibon af2450
        ├── foo.git
Pierre-Yves Chibon af2450
        └── bar.git
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon 24cf2b
to: ::
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon 24cf2b
    repos/
Pierre-Yves Chibon 24cf2b
    ├── foo.git
Pierre-Yves Chibon af2450
    ├── bar.git
Pierre-Yves Chibon a591b5
    └── forks/
Pierre-Yves Chibon a591b5
        ├── patrick/
Pierre-Yves Chibon a591b5
        │   ├── test.git
Pierre-Yves Chibon a591b5
        │   └── ipsilon.git
Pierre-Yves Chibon a591b5
        └── pingou/
Pierre-Yves Chibon af2450
            ├── foo.git
Pierre-Yves Chibon af2450
            └── bar.git
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon af2450
So the entire ``forks`` folder is moved under the ``repos`` folder where
Pierre-Yves Chibon af2450
the other repositories are, containing the sources of the projects.
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon 6e788b
Git repos for ``tickets``, ``requests`` and ``docs`` will be trickier to
Pierre-Yves Chibon 6e788b
move as the structure changes from: ::
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon 24cf2b
    tickets/
Pierre-Yves Chibon 24cf2b
    ├── foo.git
Pierre-Yves Chibon af2450
    ├── bar.git
Pierre-Yves Chibon a591b5
    ├── patrick/
Pierre-Yves Chibon a591b5
    │   ├── test.git
Pierre-Yves Chibon a591b5
    │   └── ipsilon.git
Pierre-Yves Chibon a591b5
    └── pingou/
Pierre-Yves Chibon af2450
        ├── foo.git
Pierre-Yves Chibon af2450
        └── bar.git
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon 24cf2b
to: ::
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon 24cf2b
    tickets/
Pierre-Yves Chibon 24cf2b
    ├── foo.git
Pierre-Yves Chibon af2450
    ├── bar.git
Pierre-Yves Chibon a591b5
    └── forks/
Pierre-Yves Chibon a591b5
        ├── patrick/
Pierre-Yves Chibon a591b5
        │   ├── test.git
Pierre-Yves Chibon a591b5
        │   └── ipsilon.git
Pierre-Yves Chibon a591b5
        └── pingou/
Pierre-Yves Chibon af2450
            ├── foo.git
Pierre-Yves Chibon af2450
            └── bar.git
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon 6e788b
Same for the ``requests`` and the ``docs`` git repos.
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon 6e788b
As you can see in the ``tickets``, ``requests`` and ``docs`` folders there
Pierre-Yves Chibon 6e788b
are two types of folders, git repos which are folder with a name ending
Pierre-Yves Chibon 6e788b
with ``.git``, and folder corresponding to usernames. These last ones are
Pierre-Yves Chibon 6e788b
the ones to be moved into a subfolder ``forks/``.
Pierre-Yves Chibon 6e788b
Pierre-Yves Chibon 6e788b
This can be done using something like: ::
Pierre-Yves Chibon 6e788b
Pierre-Yves Chibon 6e788b
    mkdir forks
Pierre-Yves Chibon 6e788b
    for i in `ls -1 |grep -v '\.git'`; do mv $i forks/; done
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon 24cf2b
* Re-generate the gitolite configuration.
Pierre-Yves Chibon 24cf2b
Pierre-Yves Chibon 24cf2b
This can be done via the ``Re-generate gitolite ACLs file`` button in the
Pierre-Yves Chibon 24cf2b
admin page.
Pierre-Yves Chibon 226c9a
Pierre-Yves Chibon 226c9a
* Keep URLs backward compatible
Pierre-Yves Chibon 226c9a
Pierre-Yves Chibon 6e59c1
The support of pseudo-namespace in pagure 2.0 has required some changes
Pierre-Yves Chibon 226c9a
to the URL schema:
Pierre-Yves Chibon 226c9a
https://pagure.io/pagure/053d8cc95fcd50c23a8b0a7f70e55f8d1cc7aebb
Pierre-Yves Chibon 226c9a
became:
Pierre-Yves Chibon 226c9a
https://pagure.io/pagure/c/053d8cc95fcd50c23a8b0a7f70e55f8d1cc7aebb
Pierre-Yves Chibon 226c9a
(Note the added /c/ in it)
Pierre-Yves Chibon 226c9a
Pierre-Yves Chibon 226c9a
We introduced a backward compatibility fix for this.
Pierre-Yves Chibon 226c9a
Pierre-Yves Chibon 226c9a
This fix is however *disabled* by default so if you wish to keep the URLs
Pierre-Yves Chibon 226c9a
valid, you will need to adjust you configuration file to include: ::
Pierre-Yves Chibon 226c9a
Pierre-Yves Chibon 226c9a
    OLD_VIEW_COMMIT_ENABLED = True
