Unreleased
==========
Changes in synapse <unreleased>
===============================
synctl no longer starts the main synapse when using ``-a`` option with workers.
A new worker file should be added with ``worker_app: synapse.app.homeserver``.
Potentially breaking change:
* Make Client-Server API return 401 for invalid token (PR #3161).
This changes the Client-server spec to return a 401 error code instead of 403
when the access token is unrecognised. This is the behaviour required by the
specification, but some clients may be relying on the old, incorrect
behaviour.
Thanks to @NotAFile for fixing this.
Changes in synapse v0.28.1 (2018-05-01)
=======================================
SECURITY UPDATE
* Clamp the allowed values of event depth received over federation to be
[0, 2^63 - 1]. This mitigates an attack where malicious events
injected with depth = 2^63 - 1 render rooms unusable. Depth is used to
determine the cosmetic ordering of events within a room, and so the ordering
of events in such a room will default to using stream_ordering rather than depth
(topological_ordering).
This is a temporary solution to mitigate abuse in the wild, whilst a long term solution
is being implemented to improve how the depth parameter is used.
Full details at
https://docs.google.com/document/d/1I3fi2S-XnpO45qrpCsowZv8P8dHcNZ4fsBsbOW7KABI
* Pin Twisted to <18.4 until we stop using the private _OpenSSLECCurve API.

Changes in synapse v0.27.4 (2018-04-13)
======================================
Changes:
* Update canonicaljson dependency (#3095)
Changes in synapse v0.27.3 (2018-04-11)
======================================
Bug fixes:

Changes in synapse v0.27.3-rc2 (2018-04-09)
==========================================
v0.27.3-rc1 used a stale version of the develop branch so the changelog overstates
the functionality. v0.27.3-rc2 is up to date, rc1 should be ignored.
Changes in synapse v0.27.3-rc1 (2018-04-09)
=======================================
Notable changes include API support for joinability of groups. Also new metrics
and phone home stats. Phone home stats include better visibility of system usage
so we can tweak synpase to work better for all users rather than our own experience
with matrix.org. Also, recording 'r30' stat which is the measure we use to track
overal growth of the Matrix ecosystem. It is defined as:-
Counts the number of native 30 day retained users, defined as:-
* Users who have created their accounts more than 30 days
* Where last seen at most 30 days ago
* Where account creation and last_seen are > 30 days"
Features:
* Add joinability for groups (PR #3045)
* Implement group join API (PR #3046)
* Add counter metrics for calculating state delta (PR #3033)
* R30 stats (PR #3041)
* Measure time it takes to calculate state group ID (PR #3043)
* Add basic performance statistics to phone home (PR #3044)
* Add response size metrics (PR #3071)
* phone home cache size configurations (PR #3063)
Changes:
* Add a blurb explaining the main synapse worker (PR #2886) Thanks to @turt2live!
* Replace old style error catching with 'as' keyword (PR #3000) Thanks to @NotAFile!
* Use .iter* to avoid copies in StateHandler (PR #3006)
* Linearize calls to _generate_user_id (PR #3029)
* Remove last usage of ujson (PR #3030)
* Use simplejson throughout (PR #3048)

* Fix replication after switch to simplejson (PR #3015)
* 404 correctly on missing paths via NoResource (PR #3022)
* Fix error when claiming e2e keys from offline servers (PR #3034)
* fix tests/storage/test_user_directory.py (PR #3042)
* use PUT instead of POST for federating groups/m.join_policy (PR #3070) Thanks to @krombel!
* postgres port script: fix state_groups_pkey error (PR #3072)
Changes in synapse v0.27.2 (2018-03-26)

Bug fixes:
* Fix bug which broke TCP replication between workers (PR #3015)

Changes in synapse v0.26.1 (2018-03-15)
=======================================
Bug fixes:
* Fix bug where an invalid event caused server to stop functioning correctly,
due to parsing and serializing bugs in ujson library (PR #3008)
Changes in synapse v0.27.0-rc1 (2018-03-14)
===========================================
The common case for running Synapse is not to run separate workers, but for those that do, be aware that synctl no longer starts the main synapse when using ``-a`` option with workers. A new worker file should be added with ``worker_app: synapse.app.homeserver``.
This release also begins the process of renaming a number of the metrics
reported to prometheus. See `docs/metrics-howto.rst <docs/metrics-howto.rst#block-and-response-metrics-renamed-for-0-27-0>`_.
Note that the v0.28.0 release will remove the deprecated metric names.
Features:
* Add ability for ASes to override message send time (PR #2754)
* Add support for custom storage providers for media repository (PR #2867, #2777, #2783, #2789, #2791, #2804, #2812, #2814, #2857, #2868, #2767)
* Add purge API features, see `docs/admin_api/purge_history_api.rst <docs/admin_api/purge_history_api.rst>`_ for full details (PR #2858, #2867, #2882, #2946, #2962, #2943)
* Add support for whitelisting 3PIDs that users can register. (PR #2813)
* Add ``/room/{id}/event/{id}`` API (PR #2766)
* Add an admin API to get all the media in a room (PR #2818) Thanks to @turt2live!
* Add ``federation_domain_whitelist`` option (PR #2820, #2821)
Changes:
* Continue to factor out processing from main process and into worker processes. See updated `docs/workers.rst <docs/workers.rst>`_ (PR #2892 - #2904, #2913, #2920 - #2926, #2947, #2847, #2854, #2872, #2873, #2874, #2928, #2929, #2934, #2856, #2976 - #2984, #2987 - #2989, #2991 - #2993, #2995, #2784)
* Ensure state cache is used when persisting events (PR #2864, #2871, #2802, #2835, #2836, #2841, #2842, #2849)
* Change the default config to bind on both IPv4 and IPv6 on all platforms (PR #2435) Thanks to @silkeh!
* No longer require a specific version of saml2 (PR #2695) Thanks to @okurz!
* Remove ``verbosity``/``log_file`` from generated config (PR #2755)
* Add and improve metrics and logging (PR #2770, #2778, #2785, #2786, #2787, #2793, #2794, #2795, #2809, #2810, #2833, #2834, #2844, #2965, #2927, #2975, #2790, #2796, #2838)
* When using synctl with workers, don't start the main synapse automatically (PR #2774)
* Minor performance improvements (PR #2773, #2792)
* Use a connection pool for non-federation outbound connections (PR #2817)
* Make it possible to run unit tests against postgres (PR #2829)
* Update pynacl dependency to 1.2.1 or higher (PR #2888) Thanks to @bachp!
* Remove ability for AS users to call /events and /sync (PR #2948)
* Use bcrypt.checkpw (PR #2949) Thanks to @krombel!
Bug fixes:
* Fix broken ``ldap_config`` config option (PR #2683) Thanks to @seckrv!
* Fix error message when user is not allowed to unban (PR #2761) Thanks to @turt2live!

Running the Integration Tests
=============================
Synapse is accompanied by `SyTest <https://github.com/matrix-org/sytest>`_,
a Matrix homeserver integration testing suite, which uses HTTP requests to
access the API as a Matrix client would. It is able to run Synapse directly from
the source tree, so installation of the server is not required.
Testing with SyTest is recommended for verifying that changes related to the
Client-Server API are functioning correctly. See the `installation instructions
<https://github.com/matrix-org/sytest#installing>`_ for details.

Upgrading to $NEXT_VERSION
====================
This release expands the anonymous usage stats sent if the opt-in
``report_stats`` configuration is set to ``true``. We now capture RSS memory
and cpu use at a very coarse level. This requires administrators to install
the optional ``psutil`` python module.
We would appreciate it if you could assist by ensuring this module is available
and ``report_stats`` is enabled. This will let us see if performance changes to
synapse are having an impact to the general community.

If the event is invalid, then this method throws a FederationError.
(The error will then be logged and sent back to the sender (which

transaction will be processed as normal).
It is likely that we'll then receive other events which refer to
this rejected_event in their prev_events, etc. When that happens,
we'll attempt to fetch the rejected event again, which will presumably
fail, so those second-generation events will also get rejected.
Eventually, we get to the point where there are more than 10 events
between any new events and the original rejected event. Since we
only try to backfill 10 events deep on received pdu, we then accept the
new event, possibly introducing a discontinuity in the DAG, with new
forward extremities, so normal service is approximately returned,
until we try to backfill across the discontinuity.
Args:
origin (str): server which sent the pdu
pdu (FrozenEvent): received pdu
Returns (Deferred): completes with None
Raises: FederationError if the signatures / hash do not match
Raises: FederationError if the signatures / hash do not match, or
