12.0.0 (2019-01-10)

Breaking changes

• Remove Python 3.5 support and upgrade to Python 3.6. (#1886)
• Remove record from UnicityError class (#1919). This enabled us to fix #1545.
• Storage backend API has changed, notions of collection and records were replaced by the generic terms resource and object. Plugins that subclass the internal ShareableResource class may also break.
• GET requests no longer include the Total-Records header. To get a count in a collection you need to do a HEAD request. And the new header name is Total-Objects. (#1624)
• Remove the UserResource class. And ShareableResource is now deprecated in favor of Resource.
• Removed kinto.core.utils.parse_resource()`. Use ``kinto.core.utils.view_lookup_registry() instead (#1828)
• Remove delete-collection command (#1959)

API is now at version 1.21. See API changelog.

New features

• Add a user-data endpoint at /__user_data__/ which can be used to delete all data associated with a principal. This might be helpful for pursuing GDPR compliance, for instance. (Fixes #442.)

Bug Fixes

• Like query now returns 400 when a non string value is used. (#1899)
• Record ID is validated if explicitly mentioned in the collection schema (#1942)
• The Memory permission backend implementation of remove_principal is now less generous with what it removes (#1955).

Documentation

11.2.0 (2018-11-29)

New features

• Return a 500 Internal Error on __version__ instead of 404 if the version file cannot be found (fixes #1841)

Bug fixes

• Fix the http_api_version exposed in the /v1/ endpoint. The version 1.20 was getting parsed as a number 1.2.
• Fix record:create not taken into account from settings. (fixes #1813)

Internal changes

• Build the admin on the CI. (#1857)
• Migrate JSON Hyper-Schema to Draft-07 (#1808)

Documentation

• Add documentation on troubleshooting Auth0 multiauth issue. (#1889)

11.1.0 (2018-10-25)

New features

• Add ability to configure the project_name in settings, shown in the root URL (fixes #1809)
• Use . as bucket/collection separator in cache control settings (fixes #1815)

Bug fixes

Internal changes

• Use mock from the standard library.
• Blackify the whole code base (#1799, huge thanks to @Cnidarias for this!)
• Upgrade kinto-admin to v1.22

11.0.0 (2018-10-09)

Breaking changes

• The basicauth policy is not used by default anymore (#1736)

If your application relies on this specific behaviour, you now have to add explicitly settings:

multiauth.policies = basicauth

But it is recommended to use other authentication policies like the OpenID Connect or the accounts plugin instead.

# Enable plugin.
kinto.includes = kinto.plugins.accounts

# Enable authenticated policy.
multiauth.policies = account
multiauth.policy.account.use = kinto.plugins.accounts.AccountsPolicy

# Allow anyone to create their own account.
kinto.account_create_principals = system.Everyone

You will find more details the authentication settings section of the documentation

Bug fixes

• Fix crash when querystring filter contains NUL (0x00) character (fixes #1704)
• Many bugs were fixed in the Kinto Admin UI (see v1.21.0)

Documentation

• Huge refactor of documentation about authentication (#1736)

Internal changes

• Upgrade kinto-admin to v1.21.0
• Deprecate assertEquals and use assertEqual (fixes #1780)
• Set schema to an instance instead of class (fixes #1781)
• Fix DeprecationWarning for unrecognized backslash escapes (#1758)

10.1.2 (2018-10-03)

Bug fixes

• Fix OpenID login in Kinto-Admin (Kinto/kinto-admin#641)

Internal changes

• Upgrade kinto-admin to v1.20.2

10.1.1 (2018-09-20)

Bug fixes

• Fix for adding extra OpenId providers (fixes #1509)
• Change the meaning of event.payload["timestamp"]. Previously it was @reify’d, which meant that it was calculated from before whatever thing triggered the event. Now we use a “fresh” timestamp. (Fixes #1469.)

10.1.0 (2018-09-17)

Bug fixes

• Deleting a collection doesn’t delete access_control_entrries for its children (fixes #1647)

New features

• The registry now has a “command” attribute during one-off commands such as kinto migrate. This can be useful for plugins that want to behave differently during a migration, for instance. (#1762)

10.0.0 (2018-08-16)

Breaking changes

• kinto.core.events.get_resource_events now returns a generator rather than a list.

New features

• Include Python 3.7 support.
• kinto.core.events.notify_resource_event now supports resource_name and resource_data. These are useful when emitting events from one view “as though” they came from another view.
• Resource events can now trigger other resource events, which are handled correctly. This might be handy if one resource wants to simulate events on another “virtual” resource, as in kinto-changes.

Bug fixes

• Raise a configuration error if the kinto.plugin.accounts is included without being enabled in policies. Without this kinto-admin would present a confusing login experience (fixes #1734).

Internal changes

• Upgrade kinto-admin to v1.20.0

9.2.3 (2018-07-05)

Internal changes

• Upgrade to kinto-admin v1.19.2

Bug fixes

• Fixed bug where unresolved JSON pointers would crash server (fixes #1685)

Internal changes

• Update the Dockerfile with the new kinto –cache-backend option. (#1686)
• Upgrade to kinto-admin v1.19.0

9.2.0 (2018-06-07)

API

• JSON schemas can now be defined in the bucket metadata and will apply to every underlying collection, group or record (fixes #1555)

API is now at version 1.20. See API changelog.

New features

• Kinto Admin plugin now supports OpenID Connect
• Limit network requests to current domain in Kinto Admin using Content-Security Policies
• Prompt for cache backend type in kinto init (#1653)
• kinto.core.utils now has new features route_path_registry and instance_uri_registry, suitable for use when you don’t necessarily have a request object around. The existing functions will remain in place.
• openid plugin will carry prompt=none querystring parameter if appended to authorize endpoint.

Internal changes

• Upgrade to kinto-admin v1.18.0

9.1.2 (2018-05-31)

Bug fixes

• OpenID plugin used the same cache key for every access-token (fixes #1660)

9.1.1 (2018-05-23)

Internal changes

• Correct spelling of GitHub.
• Upgrade to kinto-admin v1.17.2

9.1.0 (2018-05-21)

API

• Batch endpoint now checks for and aborts any parent request if subrequest encounters 409 constraint violation (fixes #1569)

Bug fixes

• Fix a bug where you could not reach the last records via Next-Header when deleting with pagination (fixes #1170)
• Slight optimizations on the get_all query in the Postgres storage backend which should make it faster for result sets that have a lot of records (#1622). This is the first change meant to address #1507, though more can still be done.
• Fix a bug where the batch route accepted all content-types (fixes #1529)

Internal changes

• Upgrage to kinto-admin v1.17.1

9.0.0 (2018-04-25)

API

• Introduce contains and contains_any filter operators (fixes #343).

API is now at version 1.19. See API changelog.

Breaking changes

• The storage class now exposes bump_timestamp() and bump_and_store_timestamp() methods so that memory based storage backends can use them. (#1596)

Internal changes

• Authentication policies can now hard code and override the name specified in settings

Documentation

• Version number is taken from package in order to ease release process (#1594)
• Copyright year is now dynamic (#1595)

Internal changes

• Upgrade the kinto-admin UI to 1.17.0

8.3.0 (2018-04-06)

Security fix

• Validate the account user password even when the session is cached (fixes #1583). Since Kinto 8.2.0 the account plugin had a security flaw where the password wasn’t verified during the session duration.

New features

• Add bucket and account creation permissions in the permissions endpoint (fixes #1510)

Bug fixes

• Reduce the OpenID state string length to fit in the PostgreSQL cache backend (fixes #1566)

Documentation

• Improve OpenID settings and API documentation

Internal Changes

• Now fully rely on Pyup.io (or contributors) to update the versions in the requirements.txt file (fixes #1512)
• Move from importing pip to running it in a subprocess (see https://github.com/pypa/pip/issues/5081).
• Remove useless print when using the OpenID policy (ref #1509)
• Try to recover from the race condition where two requests can delete the same record. (Fix #1557; refs #1407.)
• Fix a bug in the memory backend where paginating past the end of a list would restart pagination. (Refs #1584.)

8.2.2 (2018-03-28)

Internal changes

• Fix kinto-admin dependency error in 8.2.1 to actually really upgrade it to 1.15.1

8.2.1 (2018-03-28)

Internal changes

• Upgraded the kinto-admin to version 1.15.1
• Upgraded newrelic to 2.106.1.88

8.2.0 (2018-03-01)

New features

• Add Openid connect support (#939, #1425). See demo
• Account plugin now caches authentication verification (#1413)

Bug fixes

• Fix missing principals from user info in root URL when default bucket plugin is enabled (fixes #1495)
• Fix crash in Postgresql when the value of url param is empty (fixes #1305)

Internal Changes

• Upgraded the kinto-admin to version 1.15.0

8.1.5 (2018-02-09)

Bug fixes

• Restore “look before you leap” behavior in the Postgres storage backend create() method to check whether a record exists before running the INSERT query (#1487). This check is “optimistic” in the sense that we can still fail to INSERT after the check succeeded, but it can reduce write load in configurations where there are a lot of create()s (i.e. when using the default_bucket plugin).

8.1.4 (2018-01-31)

Bug fixes

• Allow inherited resources to set a custom model instance before instantiating (fixes #1472)
• Fix collection timestamp retrieval when the stack is configured as readonly (fixes #1474)

8.1.3 (2018-01-26)

Bug fixes

• Optimize the PostgreSQL permission backend’s delete_object_permissions function in the case where we are only matching one object_id (or object_id prefix).

8.1.2 (2018-01-24)

Bug fixes

• Flushing a server no longer breaks migration of the storage backend (#1460). If you have ever flushed a server in the past, migration may be broken. This version of Kinto tries to guess what version of the schema you’re running, but may guess wrong. See https://github.com/Kinto/kinto/wiki/Schema-versions for some additional information.

Internal changes

• We now allow migration of the permission backend’s schema.

Operational concerns

• The schema for the Postgres permission backend has changed. This changes another ID column to use the “C” collation, which should speed up the delete_object_permissions query when deleting a bucket.

8.1.1 (2018-01-18)

Operational concerns

• The schema for the Postgres storage backend has changed. This changes some more ID columns to use the “C” collation, which fixes a bug where the bump_timestamps trigger was very slow.

8.1.0 (2018-01-09)

Internal changes

• Update the Docker compose configuration to use memcache for the cache backend (#1405)
• Refactor the way postgresql.storage.create_from_settings ignores settings (#1410)

Operational concerns

• The schema for the Postgres storage backend has changed. This changes some ID columns to use the “C” collation, which will make delete_all queries faster. (See e.g. https://www.postgresql.org/docs/9.6/static/indexes-opclass.html, which says “If you do use the C locale, you do not need the xxx_pattern_ops operator classes, because an index with the default operator class is usable for pattern-matching queries in the C locale.”) This may change the default sort order and grouping of record IDs.

New features

• New setting kinto.backoff_percentage to only set the backoff header a portion of the time.
• make tdd allows development in a TDD style by rerunning tests every time a file is changed.

Bug fixes

• Optimize the Postgres collection_timestamp method by one query. It now only makes two queries instead of three.
• Update other dependencies: newrelic to 2.98.0.81 (#1409), setuptools to 38.4.0 (#1411, #1429, #1438, #1440), pytest to 3.3.2 (#1412, #1437), raven to 6.4.0 (#1421), werkzeug to 0.14.1 (#1418, #1434), python-memcached to 1.59 (#1423), zest.releaser to 6.13.3 (#1427), bravado_core to 4.11.2 (#1426, #1441), statsd to 3.2.2 (#1422), jsonpatch to 1.21 (#1432), sqlalchemy to 1.2.0 (#1430), sphinx to 1.6.6 (#1442).

8.0.0 (2017-11-29)

Breaking changes

• Storage backends no longer support the ignore_conflict argument (#1401). Instead of using this argument, consider catching the UnicityError and handling it. ignore_conflict was only ever used in one place, in the default_bucket plugin, and was eventually backed out in favor of catching and handling a UnicityError.

Bug fixes

• Fix a TOCTOU bug in the Postgres storage backend where a transaction doing a create() would fail because a row had been inserted after the transaction had checked for it (#1376).

7.6.2 (2017-11-28)

Operational concerns

• The schema for the Postgres ``storage`` backend has changed. This lets us prevent a race condition where deleting and creating a thing at the same time can leave it in an inconsistent state (#1386). You will have to run the kinto migrate command in order to migrate the schema.

Bug fixes

• Document how to create an account using the POST /accounts endpoint (#1385).

Internal changes

• Update dependency on pytest to move to 3.3.0 (#1403).
• Update other dependencies: setuptools to 38.2.1 (#1380, #1381, #1392, #1395), jsonpatch to 1.20 (#1393), zest.releaser to 6.13.2 (#1397), paste-deploy to 0.4.2 (#1384), webob to 1.7.4 (#1383), simplejson to 3.13.2 (#1389, #1390).
• Undo workaround for broken kinto-http.js in the kinto-admin plugin (#1382).

7.6.1 (2017-11-17)

Bug fixes

• Fix kinto-admin loading.

7.6.0 (2017-11-16)

Protocol

• When a record is pushed with an older timestamp, the collection timestamps is not bumped anymore. (#1361)

New features

• A new custom logging formatter is available in kinto.core. It fixes the issues of mozilla-cloud-services-logger. Consider migrating your logging settings to :

[formatter_json]
class = kinto.core.JsonLogFormatter

Bug fixes

• Do not log empty context values (ref #1363)
• Fixed some attributes in logging of errors (ref #1363)
• Fixed logging of method/path of batch subrequests (ref #1363)
• Fix removing permissions with Json Merge (#1322).

Internal changes

• Moved PostgreSQL helper function to Python code (ref #1358)

7.5.1 (2017-10-03)

Bug fixes

• Fix create-user command for PostgreSQL backend (#1340)
• Make sure create-user command updates password (#1336)

7.5.0 (2017-09-27)

• Add a memcached cache backend (#1332)

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).

Bug fixes

• The default_bucket plugin no longer sends spurious “created” 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)
• Fix crash with JSONSchema validation of unknown required properties (fixes #1243)
• Fix bug on bucket deletion where other buckets could be deleted too if their id started with the same id
• Fix permissions of accounts created with PUT by admin (ref #1248)
• Fix ownership of accounts created with POST by admin (fixes #1248)

Internal changes

Internal changes

• Upgraded the kinto-admin to version 1.13.3

7.0.0 (2017-05-15)

Breaking changes

• The flush endpoint is now a built-in plugin at kinto.plugins.flush and should be enabled using the includes section of the configuration file. KINTO_FLUSH_ENDPOINT_ENABLED environment variable is no longer supported. (#1147)
• Settings with cliquet. prefix are not supported anymore.
• Logging configuration now relies on standard Python logging module (#1150)

Before:

kinto.logging_renderer = kinto.core.logs.ClassicLogRenderer

Now:

[handler_console]
...
formatter = color

[formatters]
keys = color

[formatter_color]
class = logging_color_formatter.ColorFormatter

• Forbid storing bytes in the cache backend. (#1143)
• kinto.core.api was renamed to kinto.core.openapi (#1145)
• Logging extra information on message must be done using the extra keyword (eg. logger.info('msg', extra={a=1}) instead of logger.info('msg', a=1)) (#1110, #1150)
• Cache entries must now always have a TTL. The ttl parameter of cache.set() is now mandatory (fixes #960).
• get_app_settings() from kinto.core.testing.BaseWebTest is now a class method (#1144)

Protocol

• Groups can now be created with a simple PUT (fixes #793)

• The permissions attribute is now empty in the response if the user has not the permission 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)
• Parent attributes are now readable if children creation is allowed. That means for example 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)

• 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)

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)
