Changelog
=========

This document describes changes between each past release.

7.4.1 (2017-09-01)
------------------

- Failed to publish Kinto Admin


7.4.0 (2017-08-30)
------------------

**New features**

- Add a `create-user` kinto command (#1315)

**Bug fixes**

- Fix pagination token generation on optional fields (#1253)


7.3.2 (2017-08-14)
------------------

**Bug fixes**

- The PostgreSQL cache backend now orders deletes according to keys,
which are a well-defined order that never changes. (Fixes #1308.)

**Internal changes**

- Now all configuration options appear as commented lines on the configuration
template (#895)
- Added task on PR template about updating the configuration template
if a new configuration setting is added.
- Use json instead of ujson in storage in tests (#1255)
- Improve Docker container to follow Dockerflow recommendations (fixes #998)


7.3.1 (2017-07-03)
------------------

**Bug fixes**

- Fix bug in Postgres backend regarding the handling of combining
filters and NULL values.


7.3.0 (2017-06-23)
------------------

**New features**

- Account plugin now allows account IDs to be email addresses (fixes
#1283).

**Bug fixes**

- Make it illegal for a principal to be present in
``account_create_principals`` without also being in
``account_write_principals``. Restricting creation of accounts to
specified users only makes sense if those users are "admins", which
means they're in ``account_write_principals``. (Fixes #1281.)
- Fix a 500 when accounts without an ID are created (fixes #1280).
- Fix StatsD unparseable metric packets for the unique user counter (fixes #1282)

**Internal changes**

- Upgraded the kinto-admin to version 1.14.0


7.2.2 (2017-06-22)
------------------

**Bug fixes**

- Fix permissions endpoint when using account plugin (fixes #1276)


7.2.1 (2017-06-20)
------------------

**Bug fixes**

- Fix missing ``collection_count`` field in the rebuild-quotas script.
- Fix bug causing validation to always succeed if no required fields are present.

**Internal changes**

- Upgraded to Pyramid-tm 2 (fixes #1187)


7.2.0 (2017-06-15)
------------------

**API**

- Filtering with like can now contain wild chars (eg. ``?like_nobody=*you*``).
It is thus now impossible to search for the ``*`` character with this operator.
- Handle querystring parameters as JSON encoded values
to avoid treating number as number where they should be strings. (#1217)
- Introduce ``has_`` filter operator (fixes #344).

API is now at version **1.17**. See `API changelog`_.

**Bug fixes**

- Several changes to the handling of NULLs and how the full range of
JSON values is compared in a storage backend (PR #1258). Combined
with #1252, this should fix #1215, #1216, #1217 and #1257, as well as
possibly some others.
- Fix requests output when running with make serve (fixes #1242)
- Fix pagination on permissions endpoint (fixes #1157)
- Fix pagination when max fetch storage is reached (fixes #1266)
- Fix schema validation when internal fields like ``id`` or ``last_modified`` are
marked as required (fixes #1244)
- Restore error format for JSON schema validation errors (which was
changed in #1245).

**Internal changes**

- Add check on account plugin to avoid conflict with default ``basicauth`` policy (fixes #1177)
- Add documentation about Kinto Admin plugin (fixes #858)


7.1.0 (2017-05-31)
------------------

**New feature**

- ``delete()`` method from cache backend now returns the deleted value (fixes #1231)
- ``kinto rebuild-quotas`` script was written that can be run to
repair the damage caused by #1226 (fixes #1230).

events for buckets and collections that already exist. This causes
the ``quotas`` plugin to no longer leak "quota" when used with the
``default_bucket`` plugin. (#1226)
- Fix removal of timestamps when parent object is deleted (fixes #1233)
- Do not allow to reuse deletion tokens (fixes #1171)
- ``accounts`` plugin: fix exception on authentication. (#1224)

4.3.0 (2016-10-04)
------------------

**Protocol**

- Fix error response consistency with safe creations if the ``create`` permission
is granted (fixes #792). The server now returns a ``412`` instead of a ``403`` if
the ``If-None-Match: *`` header is provided and the ``create`` permission is granted.

to write on the object (fixes #123)
- Filtering records now works the same on the memory and postgresql backends:
if we're comparing to a number, the filter will now filter out records that
don't have this field. If we're comparing to anything else, the record
without such a field is treated as if it had '' as the value for this field.
(fixes #815)

that collection attributes are now readable to users with ``record:create`` permission.
Same applies to bucket attributes and ``collection:create`` and ``group:create`` (fixes #803)

that occured within a bucket and serves a stream of changes that can be synced.
See `API documentation <https://kinto.readthedocs.io/en/latest/api/1.x/history.html>`_.
- Added a new ``--dry-run`` option to command-line script ``migrate`` that will simulate
migration operation without executing on the backend (thanks @lavish205! #685)

Requires setting ``kinto.experimental_permissions_endpoint`` to be set to ``true``.

Protocol is now at version **1.8**. See `API changelog`_.

**Bug fixes**

- Fix crash in authorization policy when requesting ``GET /buckets/collections`` (fixes #695)
- Fix crash with PostgreSQL storage backend when provided id in POST is an integer (#688).
Regression introduced in 3.2.0 with #655.
- Fix crash with PostgreSQL storage backend is configured as read-only and reaching
the records endpoint of an unknown collection (fixes #693, related #558)
- Fix events payloads for actions in the default bucket (fixes #704)
- Fix bug in object permissions with memory backend
- Make sure the tombstone is deleted when the record is created with PUT. (#715)
- Allow filtering and sorting by any attribute on buckets, collections and groups list endpoints
- Fix crash in memory backend with Python3 when filtering on unknown field

**Internal changes**

- Resource events constructors signatures were changed. The event payload is now
built immediately when event is fired instead of during transactoin commit (#704).
- Fix crash when a resource is registered without record path.
- Changed behaviour of accessible objects in permissions backend when list of
bound permissions is empty.
- Bump ``last_modified`` on record when provided value is equal to previous
in storage ``update()`` method (#713)
- Add ability to delete records and purge tombstones with just the ``parent_id``
parameter (#711)

deleted with a single operation on storage backend (#711)
- Added ``get_objects_permissions()`` method in ``permission`` backend (#714)
- Changed ``get_accessible_objects()``, ``get_authorized_principals()`` methods
in ``permission`` backend (#714)
- Simplified and improved the code quality of ``kinto.core.authorization``,
mainly by keeping usage of ``get_bound_permissions`` callback in one place only.


3.2.0 (2016-06-14)
------------------

**Protocol**

- Allow record IDs to be any string instead of just UUIDs (fixes #655).

Protocol is now at version **1.7**. See `API changelog`_.

**New features**

- ``kinto start`` now accepts a ``--port`` option to specify which port to listen to.
**Important**: Because of a limitation in `Pyramid tooling <http://stackoverflow.com/a/21228232/147077>`_,
it won't work if the port is hard-coded in your existing ``.ini`` file. Replace
it by ``%(http_port)s`` or regenerate a new configuration file with ``kinto init``.
- Add support for ``pool_timeout`` option in Redis backend (fixes #620)
- Add new setting ``kinto.heartbeat_timeout_seconds`` to control the maximum duration
of the heartbeat endpoint (fixes #601)
- Ability to define ID generators per object type via the settings

**Bug fixes**

- Fix loss of data attributes when permissions are replaced with ``PUT`` (fixes #601)
- Fix 400 response when posting data with ``id: "default"`` in default bucket.
- Fix 500 on heartbeat endpoint when a check does not follow the specs and raises instead of
returning false.

**Internal changes**

- Renamed some permission backend methods for consistency with other classes (fixes #608)
- Removed some deprecated code that had been in ``kinto.core`` for too long.

**Documentation**

- Mention in groups documentation that the principal of a group to be used in a permissions
definition is the full URI (e.g. ``"write": ["/buckets/blog/groups/authors"]``)
- Fix typo in Github tutorial (thanks @SwhGo_oN, #673)
- New Kinto logo (thanks @AymericFaivre, #676)
- Add a slack badge to the README (#675)
- Add new questions on FAQ (thanks @enguerran, #678)

3.1.0 (2016-05-24)
------------------

**Protocol**

- Added the ``GET /contribute.json`` endpoint for open-source information (fixes #607)

Protocol is now at version **1.6**. See `API changelog`_.


**Bug fixes**

- Fix internal storage filtering when an empty list of values is provided.
- Authenticated users are now allowed to obtain an empty list of buckets on
``GET /buckets`` even if no bucket is readable (#454)
- Fix enabling flush enpoint with ``KINTO_FLUSH_ENDPOINT_ENABLED`` environment variable (fixes #588)
- Fix reading settings for events listeners from environment variables (fixes #515)
- Fix principal added to ``write`` permission when a publicly writable object
is created/edited (fixes #645)
- Prevent client to cache and validate authenticated requests (fixes #635)
- Fix bug that prevented startup if old Cliquet configuration values
were still around (#633)

**Documentation**

- Improved documentation about running in production with uWSGI (#543, #545)


3.0.1 (2016-05-20)
------------------

**Bug fixes**

- Fix crash when a cache expires setting is set for a specific bucket or collection. (#597)
- Mark old cliquet backend settings as deprecated (but continue to support them). (#596)


3.0.0 (2016-05-18)
------------------

- Major version update. Merged cliquet into kinto.core. This is
intended to simplify the experience of people who are new to Kinto.
Addresses #687.
- Removed ``initialize_cliquet()``, which has been deprecated for a while.
- Removed ``cliquet_protocol_version``. Kinto already defines
incompatible API variations as part of its URL format (e.g. ``/v0``,
``/v1``). Services based on kinto.core are free to use
``http_api_version`` to indicate any additional changes to their
APIs.
- Simplify settings code. Previously, ``public_settings`` could be
prefixed with a project name, which would be reflected in the output
of the ``hello`` view. However, this was never part of the API
specification, and was meant to be solely a backwards-compatibility
hack for first-generation Kinto clients. Kinto public settings
should always be exposed unprefixed. Applications developed against
kinto.core can continue using these names even after they transition
clients to the new implementation of their service.

**Bug fixes**

- Add an explicit message when the server is configured as read-only and the
collection timestamp fails to be saved (ref Kinto/kinto#558)
- Prevent the browser to cache server responses between two sessions. (#593)
- Redirects version prefix to hello page when trailing_slash_redirect is enabled. (#700)
- Fix crash when setting empty permission list with PostgreSQL permission backend (fixes Kinto/kinto#575)
- Fix crash when type of values in querystring for exclude/include is wrong (fixes Kinto/kinto#587)
- Fix crash when providing duplicated principals in permissions with PostgreSQL permission backend (fixes #702)
- Add ``app.wsgi`` to the manifest file. This helps address #543.


2.1.1 (2016-04-29)
------------------

**Bug fixes**

- Fix crash in JSON schema validation when additional properties are provided (fixes #548)
- Strip internal fields before validating JSON schema (fixes #549)
- Fix migration of triggers in PostgreSQL storage backend when upgrading from Kinto<2.0.
Run the ``migrate`` command will basically re-create them (fixes #559)

**Documentation**

- Fix typo in RHEL installation instructions (#552, thanks @enkidulan!)
- Link to english version of kinto presentation article (#553, thanks @glasserc!)
- Document basics about PostgreSQL privileges (#547)
- Change links from readthedocs.org to readthedocs.io (#557)

- Document how to upgrade Kinto (#537, #538)

Protocol is now in version **1.5**. See `API changelog`_.


2.0.0 (2016-03-08)
------------------

**Protocol**

- Allow buckets to store arbitrary properties. (#239, #462)
- Delete every (writable) buckets using ``DELETE /v1/buckets``
- Delete every (writable) collections using ``DELETE /v1/buckets/<bucket-id>/collections``
- Clients are redirected to URLs without trailing slash only if the current URL
does not exist (#656)

For example, ``/records?_fields=address.street``.
- List responses are now sorted by last_modified descending by default (#434,
thanks @ayusharma)
- Server now returns 415 error response if client cannot accept JSON response (#461, mozilla-services/cliquet#667)

- Add the ``__lbheartbeat__`` endpoint, for load balancer membership test.
- Add the ``flush_endpoint``, ``schema`` and ``default_bucket`` to the capabilities
if enabled in settings (#270)

Protocol is now in version **1.4**. See `API changelog`_.

**Breaking changes**

- ``kinto.plugins.default_bucket`` plugin is no longer assumed. We invite users
to check that the ``kinto.plugins.default_bucket`` is present in the
``includes`` setting if they expect it. (ref #495)
- ``kinto start`` must be explicitly run with ``--reload`` in order to
restart the server when code or configuration changes (ref #490).
- Errors are not swallowed anymore during the execution of ``ResourceChanged``
events subscribers.

Subscribers are still executed within the transaction like before.

Subscribers are still executed even if the transaction is eventually rolledback.
Every subscriber execution succeeds, or none.

Thus, subscribers of these events should only perform operations that are reversed
on transaction rollback: most likely database storage operations.

For irreversible operations see the new ``AfterResourceChanged`` event.

**New features**

- Event subscribers are now ran synchronously and can thus alter responses (#421)
- Resource events are now merged in batch requests. One event per resource and
per action is emitted when a transaction is committed (mozilla-services/cliquet#634)
- Monitor time of events listeners execution (mozilla-services/cliquet#503)
- Added a new ``AfterResourceChanged`` event, that is sent only when the commit
in database is done and successful.
`See more details <https://cliquet.readthedocs.io/en/latest/reference/notifications.html>`_.
- Track execution time on StatsD for each authentication sub-policy (mozilla-services/cliquet#639)
- Default console log renderer now has colours (mozilla-service/cliquet#671)
- Output Kinto version with ``kinto --version`` (thanks @ayusharma)

**Bug fixes**

- Fix PostgreSQL backend timestamps when collection is empty (#433)
- ``ResourceChanged`` events are not emitted if a batch subrequest fails (mozilla-services/cliquet#634)
There are still emitted if the whole batch transaction is eventually rolledback.

- Fix statsd initialization on storage (mozilla-services/cliquet#637)
- Providing bad last modified values on delete now returns 400 (mozilla-services/cliquet#665)
- Providing last modified in the past for delete now follows behaviour create/update (mozilla-services/cliquet#665)
- Do not always return 412 errors when request header ``If-None-Match: *``
is sent on ``POST /collection`` (fixes #489, mozilla-service/cliquet#673)
- Fix secret in ini on Python 3 (fixes #341)

- Add a ``bucket`` attribute in ``user`` mapping allowing clients
to obtain the actual id of their default bucket
- Add the ``protocol_version`` to tell which protocol version is
implemented by the service. (#324)

- ``_since`` and ``_before`` now accepts an integer value between quotes ``"``,
as it would be returned in the ``ETag`` response header.

``*_max_overflow``, ``*_pool_recycle``, ``*_pool_timeout`` to
control connections pool behaviour.
