Description:

Kotti 2.0.9

Kotti is a high-level, Pythonic web application framework based on Pyramid and SQLAlchemy.
It includes an extensible Content Management System called the Kotti CMS (see below).
Kotti is most useful when you are developing applications that

have complex security requirements,
use workflows, and/or
work with hierarchical data.

Built on top of a number of best-of-breed software components,
most notably Pyramid and SQLAlchemy,
Kotti introduces only a few concepts of its own,
thus hopefully keeping the learning curve flat for the developer.

Kotti CMS
Kotti CMS is a content management system that’s heavily inspired by Plone.
Its main features are:

User-friendliness: editors can edit content where it appears;
thus the edit interface is contextual and intuitive
WYSIWYG editor: includes a rich text editor
Responsive design: Kotti builds on Bootstrap, which
looks good both on desktop and mobile
Templating: you can extend the CMS with your own look & feel
with almost no programming required
Add-ons: install a variety of add-ons and customize them as well
as many aspects of the built-in CMS by use of an INI configuration
file
Security: the advanced user and permissions management is
intuitive and scales to fit the requirements of large organizations
Internationalized: the user interface is fully translatable,
Unicode is used everywhere to store data

License
Kotti is offered under the BSD-derived Repoze Public License.

Change History

2.0.9 - 2022-05-05

Replace py-bcrypt (unmaintained, last release in 2013) with bcrypt.
Pin bleach to <5 (incompatible API changes).

2.0.8 - 2022-05-05

Brownbag release (hidden).

2.0.7 - 2021-09-02

Add compatibility for (and require) SQLAlchemy 1.4.
Fix url_normalizer tests (not picked up before).
Optimize traversal for applications with large Node subclass hierarchies.
Add proper caching for get_root.

2.0.6 - 2021-05-12

Fix performance issue: Content._tags is configured with lazy="select" now.
This doesn’t cause any change in API usage, however it speeds up selects on Node and descendants by 1-2 orders of magnitude in some cases at the price of a slight performance degradation in scenarios with few tables and heavy tag usage.
Update dependencies to their most recent compatible versions.

2.0.5 - 2021-03-16

Fix sanitizer error when values are None (ie nothing to sanitize at all).
Pin Pyramid to < 2 (for now).
Pin SQLAlchemy to < 1.4 to prevent no longer working private import in sqlalchemy-utils.

2.0.4 - 2020-11-20

Replace deprecated bleach_whitelist with its successor bleach-allowlist.
Upgrade iso8601.

2.0.3 - 2020-11-18

Upgrade to pytest>=6.
Replace pytest-pep8 with pytest-flake8; fix or silence flake8 warnings/errors
in existing code (mostly tests and migrations).

2.0.2 - 2020-06-22

Upgrade requirements.txt. [fixes #576]
Remove CircleCI
Fix broken tags widget (#562).
Run pyupgrade --py36-plus on all Python files to use some more modern language
features where appropriate (for example f-strings).
Declare Python 3.7 and 3.8 compatibility.
Remove Python 3.5 compatibility.
Remove rfc6266-parser dependency.

2.0.1 - 2019-01-09

Reformat source code with black.
Remove testing import from package code.

2.0.0 - 2019-01-07

Update documentation (kotti-cookiecutter is the new scaffolding template).
See https://github.com/Kotti/kotti-cookiecutter
Require pytest >= 4.1.0, use request.node.get_closest_marker instead of
deprecated request.keywords.

2.0.0b2 - 2018-04-04

Fix CSRF issue in @@share view (#551).

2.0.0b1 - 2018-03-19

Remove links to the demo site, which has been down for too long.

2.0.0a1 - 2018-02-22
This is a alpha release. Blindly upgrading your production environments will make the universe collapse!

Backward Incompatibilities

Python 3 compatibility
Kotti now runs on Python >= 3.5.
Python 2.x support was dropped entirely and won’t come back until somebody implements it or is willing to pay for it.

Everything marked as deprecated in Kotti 1.x was removed.
Scaffolding support via pcreate was dropped as it’s deprecated by Pyramid now.
An alternate solution (cookiecutter template) might become available again in the future.

New Features

Python 3 compatibility
Extensive testing and code analysis on Circle CI, Travis CI and Scrutinizer.

Fixes

Avoid deprecation warning pyramid.security.has_permission

1.3.2 - 2018-04-04
This release fixes a CSRF (Cross Site Request Forgery) security vulnerablity which was reported in #551. You should upgrade your installations ASAP.

1.3.1 - 2018-01-17

When rendering slot views, use request.blank() to create the request.
This is the proper behaviour, in tune with customizing
kotti.request_factory. Also added blank() method to
kotti.testing.DummyRequest.
When authenticated, show workflow state in the edit bar. Before it was
shown only if the ‘edit’ permission was available.
Optimize the File edit form: don’t load initial file data to session data
and don’t rewrite the file data after saving the form if that data has not
been changed through the edit form.
Bugfix: when showing addable content in the menu, check if the factory has
a defined add_view. This avoids a hard crash with, for example, a content
type derived from Content that has no add_view defined.
Added nav-bar slot to edit/master.pt, edit-bar and nav-bar
slots to view/master.pt
Bugfix: Simplify 404 page, no longer crash when authenticated
Change: simplify kotti.util.LinkBase.selected(): use request.view_name
instead of deriving the view name from request.url. Also, consider the View
editor bar entry as selected even when the url doesn’t end with a slash ‘/’
Feature: add Czech translation.
remove pytest-warnings from test dependencies (already integrated in
modern pytest versions)

1.3.0 - 2016-10-10

Breaking Changes

Upgrade to repoze.workflow==1.0b. If your application has a custom
``workflow.zcml``, it needs a little modification: ``state`` and
``transition`` titles are no longer ``key`` nodes, but attributes on the
respective ``state`` or ``transition`` nodes. See Kotti’s ``workflow.zcml``
for an example.

Features and Fixes

Add a fallback in contents.pt when creation_date or
modification_date is None.
Transform workflow state title to TranslationStrings without eval and
deprecate it.
Replace some Python 2 only code with equivalents that also support Python 3.
Use generic SQLAlchemy type Text as base type for JsonType. This allows
SQLAlchemy to map Text type to the most suitable type available on given
database system. Previously used TEXT type is not available in Oracle
database. In case of existing installation of Kotti with database system,
for which SQLAlchemy maps generic Text type to type different than TEXT it’s
necessary to either convert existing columns “nodes._acl” and
“nodes.annotations” to that type or configure SQLAlchemy to map generic Text
type to existing type of these two columns. For example of how to do this
please see http://stackoverflow.com/a/36506666/95735. For all database
systems for which SQLAlchemy provides dialects except Oracle (Firebird,
Microsoft SQL Server, MySQL, Postgres, SQLite, Sybase) there’s no need to
do anything.
We use PEP 440 normalized form for the project’s version thus current
“1.3.0-alpha.5-dev” became “1.3.0a5.dev0”.
Upgrade tests to zope.testbrowser>=5.0.0. This removes the mechanize
and wsgi_intercept dependencies and thus the last blocker for Python 3
compatibility.
Move pytest config from setup.cfg to new pytest.ini. This
prevents a deprecation warning with pytest>=3.0.
Rename kotti.testing.TestingRootFactory to
kotti.testing.RootFactory to prevent another deprecation warning with
pytest>=3.0.

1.3.0-alpha.4 - 2015-01-15
This is a alpha release. Blindly upgrading your production environments will
make the universe collapse!

Add a kotti.depot_replace_wsgi_file_wrapper option to replace the WSGI
file wrapper with pyramid.response.FileIter for problematic environments.

1.3.0-alpha.3 - 2016-01-11
This is a alpha release. Blindly upgrading your production environments will
make the universe collapse!

Bugfix: don’t try to get api.root via the lineage if not in a location aware
context (for example 404 view). Return the site root instead.

1.3.0-alpha.2 - 2016-01-05
This is a alpha release. Blindly upgrading your production environments will
make the universe collapse!

Add a custom traverser, which gets all nodes in a single DB query. For deeply
nested trees this results in drastic performance improvements. See
https://kotti.readthedocs.io/en/master/api/kotti.traversal.html for details.
Bugfix: copy and paste of file nodes wouldn’t create a new depot file, but
instead lead to multiple references to a single file which would cause
undesired results when one of them was deleted later.
Bugfix: local ‘role:owner’ was not set when a new node was created by copy
and paste.
Bugfix: kotti.events._update_children_paths could fail under unclear
conditions (at least under Python 2.6 with SQLite).
Get rid of more browser doctests (converted to webtest).

1.3.0-alpha.1 - 2015-12-22
This is a alpha release. Blindly upgrading your production environments will
make the universe collapse!

Completely revised Depot integration. See
https://kotti.readthedocs.io/en/latest/developing/advanced/blobs.html
for details.
Make kotti.resources.SaveDataMixin more versatile in that it now supports
a data_filters attribute (or even a completely overridden data
attribute) on subclasses. For an example for what this is useful, see the
new kotti_image package’s readme and the Depot documentation
(https://depot.readthedocs.io/en/latest/database.html#custom-behaviour-in-attachments).
These changes require a database migration.
A migration script is included, which can be executed by running
kotti-migrate <your.ini> upgrade_all. However, this script will fail if
you subclassed from kotti.resources.Image in your application. It also
doesn’t cover custom classes inherited from kotti.resources.File (other
than Kotti’s Image). Migration of those can be performed easily, by
copying the code from the included migration step to your package’s migration
environment and adjust it to your needs.

Move all image related code to the new kotti_image add on package.
All classes and functions are imported into their former place, so that code
that imports from there will still be working.
Fix broken upload type selector.
Create RFC6266 compliant content disposition headers for non-ASCII filenames.
Add request.uploaded_file_response method.

1.2.4 - 2015-11-26

Fix broken packaging of 1.2.3. Sorry for the inconvenience!

1.2.3 - 2015-11-26

Add Kotti logo and icon to static assets.
Use Kotti logo as favicon.
Move favicon definition to separate template to make it easily overridable.
Fix permission check in kotti.views.util.nodes_tree.

1.2.2 - 2015-10-28

Add simple, default not found view.
In workflow-dropdown replace hard-coded permission check with individual
permission checks for each existing transition.
Upgrade requirements.

1.2.1 - 2015-10-07

Outfactor the code that runs after successful authentication into a
configurable kotti.login_success_callback function.
Outfactor the code that runs after a valid password reset request into a
configurable kotti.password_reset_callback function.
Support principal search on non string attributes.
Support principal searches matching all arguments
(i.e. using the and operator, or is still the default).
Support optional –rev with kotti-migrate upgrade.

1.2.0 - 2015-09-27

Greatly reduce the number of queries that are sent to the DB:
- Add caching for the root node.
- Use eager / joined loading for local_groups.
- Don’t query principals for roles
Add “missing” foreign key indices (with corresponding migration step).
Add a kotti.modification_date_excludes configuration option.
It takes a list of attributes in dotted name notation that should not trigger
an update of modification_date on change. Defaults to
kotti.resources.Node.position.
Don’t try to set a caching header from the NewRequest handler when Pyramid’s
tweens didn’t follow the usual chain of calls. This fixes compatibility with
bowerstatic.
Don’t assume renderer_name exists in a rendering event (ex.
BeforeRender). The official docstring of pyramid.interfaces.IRenderer is
a bit ambigous in regards to what the system parameter should include
when a renderer gets called. This fixes compatibility with
pyramid_layout.
Add a kotti.modification_date_excludes configuration option.
It takes a list of attributes in dotted name notation that should not trigger
an update of modification_date on change. Defaults to
kotti.resources.Node.position.

1.1.5 - 2015-09-04

Fix migration error on MySQL.
Only wrap methods that do exist on the wrapped type (in
kotti.sqla.MutationList / kotti.sqla.MutationDict). This
fixes an error that occurs when MutationLists are exposed to the UI
via colander.SequenceSchema.
Upgrade requirements to latest versions (filedepot, waitress).

1.1.4 - 2015-06-27

Add compatibility with SQLAlchemy 1.0. Also require SQLAlchemy 1.0.6 now.
Ignore HTTPForbidden exceptions during slot rendering

1.1.3 - 2015-06-17

Fix a bug in kotti-migrate that prevented initial migration steps from being
run successfully.
Require kotti_tinymce 0.5.3.

1.1.2 - 2015-06-12

Enlarge column sizes for name, path and title (see #427).
Upgrading from any version older than 1.1.2 requires you to run a migration
script on your database. To run the migration, call:
$ bin/kotti-migrate <myconfig.ini> upgrade

Add length validator for title (fix partially #404). See #428
Remove 40 chars max length constraint for the html segment name
(Kotti.util.title_to_name). See #428
Update italian translation
Update documentation
Add an add_permission attribute to kotti.resources.TypeInfo with a
default value of add. See #436
Add a “cancel” button to the delete node view.

1.1.1 2015-05-11

Update scaffold’s README file. See #417.
Fix broken multifile upload. See #425.

1.1.0 2015-04-16

Separate the default actions to a kotti.resources.default_actions
variable, to allows easier customization of default actions of all
content types. This is a LinkParent, you can append new
kotti.util.Link objects to its children.
Add target option to kotti.util.Link. See #405.
Add sanitizers. See docs/development/advanced/sanitizers and
kotti.sanitizers for details. This fixes #296.
Added new document on how to customize the edit interface.
See docs/development/advanced/add-to-edit-interface.
Make it easier to customize default actions by separating them to a new
kotti.resources.default_actions variable. Before, to customize them,
you’d have to change Content.type_info.edit_links[3].children, now you
can mutate default_actions directly. See
docs/development/advanced/add-to-edit-interface for details.
Upgrade WebOb, html2text, pyramid and xlwt to their latest
stable versions.

1.1.0-alpha.1 - 2015-03-19

Allow moving File and Image blob data from the database to
configurable storages. To achieve this we use filedepot, a third-party
library with several plugin storages already built in. See
docs/developing/advanced/blobs.rst for details on what this brings. Upgrading
from any version older then 1.1.0 requires you to run a migration script on
your database. To run the migration, call:
$ bin/kotti-migrate <myconfig.ini> upgrade
Please note that, before running the migration, you should take the time to
read the documentation and configure your desired storage scheme.

Allow storing blob data in the database using DBStoredFile and
DBFileStorage, a database centered storage plugin for filedepot. This
storage is the default storage for blob data, unless configured otherwise.
Added a script to migrate blob data between depot storages. See
docs/developing/advanced/blobs.rst for details on how to use it.
Simplify serving blob data by using kotti.views.file.UploadedFileResponse,
which also streams data. Please note that the default DBStoredFile still
needs to load its entire data in memory, to benefit from this feature you
should configure another default depot storage.
Added three new test fixtures: mock_filedepot, to be used in simple unit
tests with no dependency on a database session, filedepot, which
integrates with the dbsession fixture and no_filedepot, a fixture
that can be used in developing tests for new file depot plugins - by
preserving the depot configuration before and after running the test. NOTE:
in order to test edit views with uploaded data in the request, you need to
mixin the filedepot fixture.
Initialize pyramid.paster.logging for custom commands defined via
kotti.util.command, to allow log message output for kotti sessions
started via custom commands.
Remove unused kotti.js.
Remove deprecated kotti.views.slots.local_navigation and
kotti.views.slots.includeme_local_navigation. Use
kotti.views.navigation.local_navigation and
kotti.views.navigation.includeme_local_navigation instead.
Upgrade plone.scale and SQLAlchemy to their latest stable versions.
Change height property on body’s widget (RichTextField) for
improved usability. See #403.

1.0.0 - 2015-01-20

No changes.

1.0.0-alpha.4 - 2015-01-29

Added experimental Docker support. See #374.
Allow restricting add views to specific contexts. This allows third party
developers to register new content types that are addable in specific
type of contexts, by specifying context=SomeContentType in their
add view registration and having type_info.addable=['SomeContentType']
in the type info.
For documents with duplicate titles that end in a number, append a counter
instead of incrementing their number. Fixes #245
Update all requirements (except alembic) to their latest respective versions.

1.0.0-alpha.3 - 2015-01-13

Explicitly implement pyramid.interfaces.IRequest for
kotti.request.Request. This allows add-on packages to use
config.add_request_method (with reify) and
config.add_request_property without breaking the interfaces provided by
the request. Fixes #369

1.0.0-alpha.2 - 2015-01-01

Require kotti_tinymce==0.5.1. This fixes #365.

1.0.0-alpha - 2014-12-20

Add a new scaffold based on Pyramid’s pcreate. To run the tests for the
scaffold, you must invoke py.test with the --runslow option. This
is enabled by default on Travis.
kotti._resolve_dotted now return a resolved copy of the settings
(instead of in place resolving as before).
Factor out DBMS specific patches and make them available to the test fixtures.
Add new fixtures that can also be used in add on tests:

custom_settings does nothing and is meant to be overridden in add on
test suites. It allows injection of arbitrary key / values into the
settings dict used in tests.
unresolved_settings is guaranteed to only contain unresolved string
values (or lists therof).
settings is now guaranteed to be fully resolved.
webtest returns a webtest.TestApp instance with support for the
@user marker. This should be used instead of browser doctests for
functional tests.

Use RTD theme for documentation.
Use latest versions of all requirements. The only upgrade with notable
differences is lingua (from 1.4 to 3.6.1). This completely changes
lingua’s API. See docs/developing/basic/translations.rst for details on
the greatly simplified new usage.
Remove code (incl. tests) that has been marked as deprecated since (at least)
Kotti 0.8.
Revise UI to make better use of Bootstrap 3.
Allow parameters for move-child-position views to either be in
request.POST or request.json_body.
Don’t use Pyramid code that is marked as deprecated:

replace pyramid.security.authenticated_userid with
request.authenticated_userid.

Deprecate kotti.security.has_permission to be consistent with the
corresponding deprecation in Pyramid 1.5. You should now use
request.has_permission instead.
Make all values in Node.path end in /. This makes it consistent over
all nodes (including root) and correspond to the values of
request.resource_url. As a side effect querying becomes easier.
However, this might need adjustments in your code if you were expecting the
old path values before. A migration step for DB upgrades is included.

0.10b1 - 2014-07-11

Add a __json__ method to MutationList and MutationDict.
This is to allow Pyramid’s serializer to just work.

0.10a4 - 2014-06-19

Upgrade Pyramid to version 1.5.1.

0.10a3 - 2014-06-11

Upgrade SQLAlchemy and alembic dependencies from 0.8.2 and 0.5.0 to
0.9.4 and 0.6.5 respectively.
Do not flush within Node.path event handlers. We would
otherwise trigger object handlers with funny object states.
Fix bug with Node.path where we attach a Node instance to a
parent that has been loaded from the database, but its parents have
not been loaded yet.
Fix deprecation warnings with regard to Pyramid’s
custom_view_predicates and set_request_property. Also
deprecate kotti.views.util.is_root.

0.10a2 - 2014-06-05

Add Node.path column. This allows queries based on path, so
it’s much easier just to find all children, grandchildren etc. of a
given node:
DBSession.query(Node).filter(Node.path.startswith(mynode.path))

Adds session attribute to the request attributes to copy to the slot view request.

Migrations

Upgrading from 0.9.2 to 0.10 requires you to run a migration script
on your database. To run the migration, call:
$ bin/kotti-migrate <myconfig.ini> upgrade
Make sure you backup your database before running the migration!

0.10a1 - 2014-05-19

Kotti is now based on Bootstrap 3 (and therefore Deform 2).
THIS IS A BACKWARD INCOMPATIBLE CHANGE W.R.T. MOST TEMPLATES,
INCLUDING FORM TEMPLATES! IF YOUR PROJECT EITHER HAS TEMPLATE
CUSTOMIZATIONS OR DEPENDS ON ADD-ONS THINGS WILL LOOK BROKEN!
If you only use Kotti’s default UI, chances are good that your
application will continue to work well unchanged. Kotti’s API is
mostly unchanged and fully backward compatible though.

Rework implementation of ‘kotti.util.Link’ (‘ViewLink’) to be more
flexible.
There’s now proper support for nesting ‘edit_links’, so that the
special ‘action_links’ list is no longer necessary. Links now also
make better use of templates for rendering, and are probably easier
to customize overall.

Added compatiblity for and now require Pyramid>=1.5. #273
In tests, turned settings and setup_app into fixtures to ease
overriding.
Add kotti_context_url JS global variable. For more details on why this
is needed see:

https://github.com/Kotti/kotti_tinymce/issues/19
https://github.com/Kotti/Kotti/issues/219
https://github.com/Kotti/kotti_newsitem/issues/2
https://github.com/Kotti/kotti_calendar/issues/4

Adds delete permission needed for ‘delete’ and ‘delete_nodes’
views. The default workflow was updated in consequence. It allows to
elaborate more fine grained workflows : for instance, create a role
which can edit a content but not delete it.
To make existent Kotti’s instances using default workflow
compatibles and avoid users that have ‘editor’ role (and so far,
whom have the possibility to edit and delete the content) to not be
able to delete contents, it’s needed to reset workflow with
“kotti-reset-workflow <application ini file>” command.

Fix #308: Unique name constraint issue during paste of a cut node.

0.9.2 - 2013-10-15

Fix #268: Convert None to colander.null in get_appstruct so that
serialization doesn’t fail (needed due to recent changes in colander).

0.9.1 - 2013-09-25

Allow user admins to modify user passwords.
Require newer kotti_tinymce (source code editing was broken in 0.4).

0.9 - 2013-09-17

Add multi file content upload. You can now select several files from your
local storage that you want to upload and chose what content nodes shall be
created in your Kotti site. Currently files with MIME types of image/*
can be uploaded and be created as either Image or File nodes, all
other MIME types will be created as File. In future releases (or add-on
products) this can be extended with additional converters allowing for example
to upload HTML files and create Document nodes with the content of the
title tag becoming the node’s title, the content of the body tag
becoming the node’s body and so on.
Fix #253: Many translations weren’t included in the last release.
‘–use-fuzzy’ translations when running ‘compile_catalog’ adds back
translations that were recently marked as fuzzy. (All translations
that were marked as fuzzy in German were still accurate.)

Fix #252: Wrap templates where extract_messages failed with <tal:block>
Fix #249: TinyMCE translations work again.

0.9b2 - 2013-08-20

Fix #251: Broken comparison of NestedMutationDict and NestedMutationList.
Update kotti_tinymce to version 4.0.2.
Fix bug in kotti.views.content.FileEditForm to preserve file
content while editing it.

0.9b1 - 2013-06-26

Add kotti.util.ViewLink.visible method for better control over
whether a view link should be visible or not. This allows us to
move formerly hardcoded action links defined in
kotti.views.edit.actions into TypeInfo.action_links and thus
make them configurable either globally or per content type.
kotti.security.view_permitted will now check for
pyramid.security.view_execution_permitted with a request method
set to ‘GET’ by default. It used to check for a view that matches
the current request’s method.
This fixes an issue where kotti.util.ViewLink.permitted would by
mistake check for a ‘POST’ view when the current request was ‘POST’.

Add INavigationRoot interface and TemplateAPI.navigation_root
property. The latter returns the first content node in the lineage that
implements INavigationRoot or the root node if INavigationRoot is not
implemented by any node in the lineage. Make the nav.pt template use
api.navigation_root instead of api.root. This allows third party
add-ons to define content types that can reside somewhere in the content tree
while still being the root for the navigation.
Move navigation related view code to new module kotti.views.navigation.
Deprecate imports from the old locations.
Remove some code that has been deprecated in 0.6 or 0.7.
A view assigned to a slot can access the slot name where its rendered.
Add missing transaction.commit() in kotti-reset-workflow.
Fix bug in kotti.views.util.render_view where local roles weren’t
respected correctly.
Add helper method kotti.message.send_email for sending general
emails. These emails must follow a particular structure. Look at
kotti:templates/email-set-password.pt as an example.

0.9a2 - 2013-05-04

Fix #222: Use SQLAlchemy’s before_flush event for object events.
We were using the wrong events previously. The problem with
before_insert, before_update, and before_delete was that event
handlers could not reliably call Session.add, Session.delete,
and change mapped relationships. But only SQLAlchemy 0.8 started
emitting a warning when that was done.
Also deprecated ObjectAfterDelete because I don’t think it’s useful.

Remove the html5shim from the master templates and use the fanstatic
package js.html5shiv instead.
A temporary fix for #187. Basically suppresses DetachedInstanceError.
Add kotti.events.subscribe decorator. See the also updated docs on that
topic / module for details.

0.9a1 - 2013-03-12

Fix ordering on how include_me functions are loaded. This puts
Kotti’s own and Kotti add-on search paths in front of
deform_bootstrap’s.
Add image thumbs with preview popovers to @@contents view.
Add drag’n’drop ordering support to @@contents view.
Add “toggle all” checkbox to @@contents view.
Add contents path bar to @@contents view.

0.8 - 2013-03-12

No changes.

0.8b2 - 2013-02-08

Fix Kotti’s tests to no longer trigger deprecation warnings.
Kotti’s funcargs need to be better documented still, see #141.
Add a fanstatic.Group ‘tagit’ and need() it in the defered widget. This is
needed to make the tags widget render correctly with a theme package enabled
until the defered widget is replaced by a widget class that declares its
requirements in the usual deform style.
Transform setup_users, setup_user and prefs views into
class-based views. Add a little text at subsection Security on
developer manual mentioning those views.

0.8b1 - 2012-12-30

No changes

0.8a2 - 2012-12-15

Remove test related dependencies on requirements.txt.
So now we need to run python setup.py dev to get testing
dependencies.
Update packages versions on requirements.txt for latest working
versions.
Added a tags display in views for documents, files, folders, and images,
where they show up as a horizontal list between description and body.
Modified general search to include simple tags searching. The default
search in Kotti works on a simple search term matching basis. Tags
searching is added here in a simple fashion also, such that you can only
search for one tag at a time, but partial matches work: searching for ‘foo’
finds content tagged ‘foo bar’. You can also search on single tags by
clicking an individual tag in the tags display of an item. More
sophisticated tags searching, just as for general search, is left to
dedicated add-ons.

0.8a1 - 2012-11-13

Make language-dependent URL normalization the default. (How to do
this used to be a cookbook entry.)
Cleanup node edit actions and use decorated view classes.
Add contents view with actions for multiple items.
Add children_with_permission method to ContainerMixin.
Add UI for default_view selection.
Deprecate ‘kotti.views.edit.generic_add’ and ‘generic_edit’. Just
use class-based forms instead.

0.7.2 - 2012-10-02

Improve installation instructions. Now uses tagged requirements.txt
file.
Added event request POST vars to the request for the slot viewlet.
Added IFile and IImage interfaces to allow for file and image
subclasses to reuse the same view (registrations).

0.7.1 - 2012-08-30

Add deletion of users to the users management.
Fix tag support for files and images.
Upgrade to Twitter Bootstrap 2.1

remove lots of CSS that is no longer needed
fix responsive layout that was broken on some phone size
screen resolutions

Add “Site Setup” submenu / remove @@setup view.

0.7 - 2012-08-16

Fix critical issue with migrations where version number would not be
persisted in the Alembic versions table.

0.7rc1 - 2012-08-14

No changes.

0.7a6 - 2012-08-07

Fix a bug with connections in the migration script. This would
previously cause Postgres to deadlock when calling
kotti-migrate.

0.7a5 - 2012-08-07

Add workflow support based on repoze.workflow. A simple
workflow is included in workflow.zcml and is active by default.
Use kotti.use_workflow = 0 to deactivate. The workflow support
adds a drop-down that allows users with state_change permission
to modify the workflow state.
Change the default layout
Kotti’s new default look is now even closer to the Bootstrap
documentation, with the main nav bar at the very top and the
edit bar right below.
Upgrade note: if you have a customized main_template and want to
use the recent changes in that template, you need to swap
positions of nav.pt and editor-bar.pt api.render_template
calls and remove the search.pt call from the main_template
(it’s now called from within nav.pt).
Everything else is completely optional.

Add migrations via Alembic. A new script kotti-migrate helps
with managing database upgrades of Kotti and Kotti add-ons. Run
kotti-migrate <your.ini> upgrade to upgrade the Kotti database
to the latest version.
Add-on authors should see the kotti.migrate module’s docstring
for more details.

Make Document.body searchable (and therefore the search feature
actually useful for the first time).
Add a “minify” command to compress CSS and JS resources.
To use it run:
python setup.py dev
python setup.py minify
The minify command assumes, that all resources are in
kotti/static/. YUI compressor is used for compression
and will be automatically installed when running
python setup.py dev. However, you still need a JVM on
your development machine to be able to use the minify
command.

Fix settings: only values for kotti* keys should be converted to
unicode strings.
Fix #89: Validate email address for uniqueness when user changes it.
Fix #91: Styling of search box.
Fix #104: Make fanstatic resources completely overridable.
Enabled deferred loading on File.data column.

Migrations

Upgrading from 0.6 to 0.7 requires you to run a migration script on
your database. To run the migration, call:
$ bin/kotti-migrate <myconfig.ini> upgrade
Make sure you backup your database before running the migration!

Upgrading to 0.7 will initialize workfow state and permissions for
all your content objects, unless you’ve overwritten
kotti-use_workflow to not use a workflow (use 0) or a custom
one.
It is important that sites that have custom permissions,
e.g. custom modifications to SITE_ACL, turn off workflow support
prior to running the upgrade script.

0.7a4 - 2012-06-25

Add minified versions JS/CSS files.
Fix #88: logging in with email.
Update translations.

0.7a3 - 2012-06-15

Include kotti.tinymce which adds plug-ins for image and file
upload and content linking to the TinyMCE rich text editor.
Slot renderers have been replaced by normal views (or viewlets).
kotti.views.slots.register has been deprecated in favour of
kotti.views.slots.assign_slot, which works similarly, but takes
a view name of a registered view instead of a function for
registration.
Switch to fanstatic for static resource management.
Upgrade note: This requires changes to existing *.ini application
configuration files. Concretely, you’ll need to add a
filter:fanstatic section and a pipeline:main section and
rename an existing app:main section to app:Kotti or the
like. Take a look at Kotti’s own development.ini for an
example.

Retire the undocumented kotti.resources.Setting class and table.
kotti.get_settings will now return registry.settings
straight, without looking for persistent overrides in the database.
Drop support for Pyramid<1.3, since we use
pyramid.response.FileResponse, and kotti_tinymce uses
pyramid.view.view_defaults.
Fix encoding error with non-ascii passwords.

0.7a2 - 2012-06-07

Do not allow inactive users to reset their password.

0.7a1 - 2012-06-01

Features

Add a new ‘Image’ content type and image scaling, originally from
the kotti_image_gallery add-on. See kotti.image_scales.*
settings.
Add search and related setting kotti.search_content.
Add subscriber to set cache headers based on caching rules. See
also related setting kotti.caching_policy_chooser.
Remove TinyMCE from the core.
Move email templates into page templates in
kotti:templates/email-set-password.pt and
kotti:templates/email-reset-password.pt. This is to make them
easier to translate and customize. This deprecates
kotti.message.send_set_password.
Add a ‘edit_inhead’ slot for stuff that goes into the edit
interface’s head. ‘inhead’ is no longer be used in
‘edit/master.pt’.

Bugs

Fix bug with group edit views.
See https://github.com/Pylons/Kotti/pull/61
Fix bug where user.last_login_date was not set during automic
login after the set password screen.

0.6.3 - 2012-05-08

Add tag support. All content objects now have tags. They can be
added in the UI using the “jQuery UI Tag-it!” widget.
See https://github.com/Pylons/Kotti/pull/55 .
Fix a bug with file download performance.

0.6.2 - 2012-04-21

Links in Navigation view lead to node view. Added edit links
to view the node’s edit form.
Hitting ‘Cancel’ now returns to the context node for add/edit views

0.6.1 - 2012-03-30

Added button to show/hide nodes from navigation in the order screen.
The ‘rename’ action now strips slashes out of names. Fixes #53.
Add Dutch translation.
Allow translation of TinyMCE’s UI (starting with deform 0.9.5)
Separated out testing dependencies. Run bin/python setup.py dev
to install Kotti with extra dependencies for testing.
Deprecate ‘kotti.includes’ setting. Use the standard
‘pyramid.includes’ instead.
Setting ‘Node.__acl__’ to the empty list will now persist the empty
list instead of setting ‘None’.
Let ‘pyramid_deform’ take care of configuring deform with
translation dirs and search paths.

0.6.0 - 2012-03-22

Add Japanese translation.
Enforce lowercase user names and email with registration and login.
Moved SQLAlchemy related stuff from kotti.util into kotti.sqla.
You can also append to ‘Node.__acl__’ now in addition to setting the
attribute.

0.6.0b3 - 2012-03-17

Have the automatic __tablename__ and polymorphic_identity
for CamelCase class names use underscores, so a class
‘MyFancyDocument’ gets a table name of ‘my_fancy_documents’ and a
type of ‘my_fancy_document’.

0.6.0b2 - 2012-03-16

Make the ‘item_type’ attribute of AddForm optional. Fixes #41.
kotti.util.title_to_name will now return a name with a maximum
length of 40. Fixes #31.

0.6.0b1 - 2012-03-15

Use declarative style instead of class mapper for SQLAlchemy resources.
Unfortunately, this change is backwards incompatible with existing
content types (not with existing databases however). Updating your
types to use Declarative is simple. See kotti_calendar for an
example:
https://github.com/dnouri/kotti_calendar/commit/509d46bd596ff338e0a88f481339882de72e49e0#diff-1

0.5.2 - 2012-03-10

A new ‘Actions’ menu makes copy, paste, delete and rename of items
more accessible.
Add German translation.
Populators no longer need to call transaction.commit()
themselves.

0.5.1 - 2012-02-27

Internationalize user interface. Add Portuguese as the first
translation.
A new ‘Add’ menu in the editor toolbar allows for a more intuitive
adding of items in the CMS.
Refine Node.copy. No longer copy over local roles per default.

0.5.0 - 2012-02-15

Move Kotti’s default user interface to use Twitter Bootstrap 2.
Add a new ‘File’ content type.
Add CSRF protection to some forms.
Remove Kotti’s FormController in favor of using pyramid_deform.
Use plone.i18n to normalize titles to URL parts.
Add a separate navigation screen that replaces the former
intelligent breadcrumbs menu.
Use pyramid_beaker as the default session factory.
Make kotti.messages.send_set_password a bit more flexible.

0.4.5 - 2012-01-19

Add ‘kotti.security.has_permission’ which may be used instead of
‘pyramid.security.has_permission’.
The difference is that Kotti’s version will set the “authorization
context” to be the context that you pass to ‘has_permission’. The
effect is that ‘list_groups’ will return a more correct list of
local roles, i.e. the groups in the given context instead of
‘request.context’.

Add a template (‘forbidden.pt’) for when user is logged in but still
getting HTTPForbidden.

0.4.4 - 2012-01-05

The “Forbidden View” will no longer redirect clients that don’t
accept ‘text/html’ to the login form.
Fix bug with ‘kotti.site_title’ setting.

0.4.3 - 2011-12-22

Add ‘kotti.root_factory’ setting which allows the override Kotti’s
default Pyramid root factory. Also, make master templates more
robust so that a minimal root with ‘__parent__’ and ‘__name__’ can
be rendered.
The ‘kotti.tests’ was factored out. Tests should now import from
‘kotti.testing’.

0.4.2 - 2011-12-20

More convenient overrides for add-on packages by better use of
‘config.commit()’.

0.4.1 - 2011-12-20

Modularize Kotti’s Paste App Factory ‘kotti.main’.
Allow explicit setting of tables that Kotti creates
(‘kotti.use_tables’).

0.4.0 - 2011-12-14

Remove configuration variables ‘kotti.templates.*’ in favour of
‘kotti.asset_overrides’, which uses Pyramid asset specs and their
overrides.
Remove ‘TemplateAPI.__getitem__’ and instead add ‘TemplateAPI.macro’
which has a similar but less ‘special’ API.
Factor snippets in ‘kotti/templates/snippets.pt’ out into their own
templates. Use ‘api.render_template’ to render them instead of
macros.

0.3.1 - 2011-12-09

Add ‘keys’ method to mutation dicts (see 0.3.0).

0.3.0 - 2011-11-30

Replace Node.__annotations__ in favor of an extended Node.annotations.
Node.annotations will attempt to not only recognize changes to
subobjects of type dict, it will also handle list objects
transparently. That is, changing arbitrary JSON structures should
just work with regard to calling node.annotations.changed() when
the structure was changed.

0.2.10 - 2011-11-22

‘api.format_datetime’ now also accepts a timestamp in addition to datetime.

0.2.9 - 2011-11-21

Remove MANIFEST.in in favour of using ‘setuptools-git’.

0.2.8 - 2011-11-21

Remove ‘PasteScript’ dependency since that would result in spurious
errors when installing Kotti. See
http://jenkins.danielnouri.org/job/Kotti/42/TOXENV=py27/console

0.2.7 - 2011-11-20

Add ‘PasteScript’ dependency.
Fix #11 where ‘python setup.py test’ would look into a hard-coded
‘bin’ directory.
Structural analysis documentation. (Unfinished; in ‘analysis’ directory
during development. Will be moved to main docs when finished.)

0.2.6 - 2011-11-17

Add Node.__annotations__ convenience attribute.
Node.__annotations__ will wrap the annotations dict in such a way
that both item and attribute access are possible. It’ll also record
changes to dicts inside dicts and mark the parent __annotations__
attribute as dirty.

Add a welcome page.
Delete the demo added in version 0.2.4.

0.2.5 - 2011-11-14

Add ‘TemplateAPI.render_template’; allow templates to be rendered
conveniently from templates.

0.2.4 - 2011-11-13

Adjust for Pyramid 1.2: INI file, pyramid_tm, Wsgiref server, pcreate and
pserve. (MO)
Add Kotti Demo source and documentation.

0.2.3 - 2011-10-28

Node.__getitem__ will now also accept a tuple as key.
folder['1', '2'] is the same as folder['1']['2'], just more
efficient.

Added a new cache decorator based on repoze.lru.

0.2.2 - 2011-10-10

Change the function signature of kotti.authn_policy_factory,
kotti.authz_policy_factory and kotti.session_factory to
include all settings from the configuration file.

0.2.1 - 2011-09-29

Minor changes to events setup code to ease usage in tests.

0.2 - 2011-09-16

No changes.

0.2a2 - 2011-09-05

Fix templates to be compatible with Chameleon 2. Also, require
Chameleon>=2.
Require pyramid>=1.2. Also, enable pyramid_debugtoolbar for
development.ini profile.

0.2a1 - 2011-08-29

Improve database schema for Nodes. Split Node class into
Node and Content.
This change is backward incompatible in that existing content types
in your code will need to subclass Content instead of Node.
The example in the docs has been updated. Also, the underlying
database schema has changed.

Improve user database hashing and local roles storage.
Compatibility fix for Pyramid 1.2.
