Merge branch 'develop' into matrix-org-hotfixes

`@cached` doesn't work on decorated functions, because it uses inspection on
the target to calculate the number of arguments.

-Changes in synapse v0.30.0 (2018-05-24)
-==========================================
-
-'Server Notices' are a new feature introduced in Synapse 0.30. They provide a
-channel whereby server administrators can send messages to users on the server.
-
-They are used as part of communication of the server policies (see ``docs/consent_tracking.md``),
-however the intention is that they may also find a use for features such
-as "Message of the day".
-
-This feature is specific to Synapse, but uses standard Matrix communication mechanisms,
-so should work with any Matrix client. For more details see ``docs/server_notices.md``
-
-Further Server Notices/Consent Tracking Support:
-
-* Allow overriding the server_notices user's avatar (PR #3273)
-* Use the localpart in the consent uri (PR #3272)
-* Support for putting %(consent_uri)s in messages (PR #3271)
-* Block attempts to send server notices to remote users (PR #3270)
-* Docs on consent bits (PR #3268)
-
-
-
-Changes in synapse v0.30.0-rc1 (2018-05-23)
-==========================================
-
-Server Notices/Consent Tracking Support:
-
-* ConsentResource to gather policy consent from users (PR #3213)
-* Move RoomCreationHandler out of synapse.handlers.Handlers (PR #3225)
-* Infrastructure for a server notices room (PR #3232)
-* Send users a server notice about consent (PR #3236)
-* Reject attempts to send event before privacy consent is given (PR #3257)
-* Add a 'has_consented' template var to consent forms (PR #3262)
-* Fix dependency on jinja2 (PR #3263)
-
-Features:
-
-* Cohort analytics (PR #3163, #3241, #3251)
-* Add lxml to docker image for web previews (PR #3239) Thanks to @ptman!
-* Add in flight request metrics (PR #3252)

-
-Changes in synapse v0.29.1 (2018-05-17)
-==========================================
-Changes:
-
-* Update docker documentation (PR #3222)
-
-Changes in synapse v0.29.0 (2018-05-16)
-===========================================
-Not changes since v0.29.0-rc1
-
-Changes in synapse v0.29.0-rc1 (2018-05-14)
-===========================================
-
-Notable changes, a docker file for running Synapse (Thanks to @kaiyou!) and a
-closed spec bug in the Client Server API. Additionally further prep for Python 3
-migration.
-
-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.
-
-Features:
-
-* Add a Dockerfile for synapse (PR #2846) Thanks to @kaiyou!

-
-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.

-# Synapse Docker
-
-The `matrixdotorg/synapse` Docker image will run Synapse as a single process. It does not provide a
-database server or a TURN server, you should run these separately.
-
-If you run a Postgres server, you should simply include it in the same Compose
-project or set the proper environment variables and the image will automatically
-use that server.
-
-## Build
-
-Build the docker image with the `docker build` command from the root of the synapse repository.
-
-```
-docker build -t docker.io/matrixdotorg/synapse .
-```
-
-The `-t` option sets the image tag. Official images are tagged `matrixdotorg/synapse:<version>` where `<version>` is the same as the release tag in the synapse git repository.
-
-You may have a local Python wheel cache available, in which case copy the relevant packages in the ``cache/`` directory at the root of the project.
-
-## Run
-
-This image is designed to run either with an automatically generated configuration
-file or with a custom configuration that requires manual edition.
-
-### Automated configuration
-
-It is recommended that you use Docker Compose to run your containers, including
-this image and a Postgres server. A sample ``docker-compose.yml`` is provided,
-including example labels for reverse proxying and other artifacts.
-
-Read the section about environment variables and set at least mandatory variables,
-then run the server:
-
-```
-docker-compose up -d
-```
-
-If secrets are not specified in the environment variables, they will be generated
-as part of the startup. Please ensure these secrets are kept between launches of the
-Docker container, as their loss may require users to log in again.
-
-### Manual configuration
-
-A sample ``docker-compose.yml`` is provided, including example labels for
-reverse proxying and other artifacts. The docker-compose file is an example,
-please comment/uncomment sections that are not suitable for your usecase.
-
-Specify a ``SYNAPSE_CONFIG_PATH``, preferably to a persistent path,
-to use manual configuration. To generate a fresh ``homeserver.yaml``, simply run:
-
-```
-docker-compose run --rm -e SYNAPSE_SERVER_NAME=my.matrix.host synapse generate
-```
-
-Then, customize your configuration and run the server:
-
-```
-docker-compose up -d
-```
-
-### Without Compose
-
-If you do not wish to use Compose, you may still run this image using plain
-Docker commands. Note that the following is just a guideline and you may need
-to add parameters to the docker run command to account for the network situation
-with your postgres database.
-
-```
-docker run \
-    -d \
-    --name synapse \
-    -v ${DATA_PATH}:/data \
-    -e SYNAPSE_SERVER_NAME=my.matrix.host \
-    -e SYNAPSE_REPORT_STATS=yes \
-    docker.io/matrixdotorg/synapse:latest
-```
-
-## Volumes
-
-The image expects a single volume, located at ``/data``, that will hold:
-
-* temporary files during uploads;
-* uploaded media and thumbnails;
-* the SQLite database if you do not configure postgres;
-* the appservices configuration.
-
-You are free to use separate volumes depending on storage endpoints at your
-disposal. For instance, ``/data/media`` coud be stored on a large but low
-performance hdd storage while other files could be stored on high performance
-endpoints.
-
-In order to setup an application service, simply create an ``appservices``
-directory in the data volume and write the application service Yaml
-configuration file there. Multiple application services are supported.
-
-## Environment
-
-Unless you specify a custom path for the configuration file, a very generic
-file will be generated, based on the following environment settings.
-These are a good starting point for setting up your own deployment.
-
-Global settings:
-
-* ``UID``, the user id Synapse will run as [default 991]
-* ``GID``, the group id Synapse will run as [default 991]
-* ``SYNAPSE_CONFIG_PATH``, path to a custom config file
-
-If ``SYNAPSE_CONFIG_PATH`` is set, you should generate a configuration file
-then customize it manually. No other environment variable is required.
-
-Otherwise, a dynamic configuration file will be used. The following environment
-variables are available for configuration:
-
-* ``SYNAPSE_SERVER_NAME`` (mandatory), the current server public hostname.
-* ``SYNAPSE_REPORT_STATS``, (mandatory, ``yes`` or ``no``), enable anonymous
-  statistics reporting back to the Matrix project which helps us to get funding.
-* ``SYNAPSE_NO_TLS``, set this variable to disable TLS in Synapse (use this if
-  you run your own TLS-capable reverse proxy).
-* ``SYNAPSE_ENABLE_REGISTRATION``, set this variable to enable registration on
-  the Synapse instance.
-* ``SYNAPSE_ALLOW_GUEST``, set this variable to allow guest joining this server.
-* ``SYNAPSE_EVENT_CACHE_SIZE``, the event cache size [default `10K`].
-* ``SYNAPSE_CACHE_FACTOR``, the cache factor [default `0.5`].
-* ``SYNAPSE_RECAPTCHA_PUBLIC_KEY``, set this variable to the recaptcha public
-  key in order to enable recaptcha upon registration.
-* ``SYNAPSE_RECAPTCHA_PRIVATE_KEY``, set this variable to the recaptcha private
-  key in order to enable recaptcha upon registration.
-* ``SYNAPSE_TURN_URIS``, set this variable to the coma-separated list of TURN
-  uris to enable TURN for this homeserver.
-* ``SYNAPSE_TURN_SECRET``, set this to the TURN shared secret if required.
-
-Shared secrets, that will be initialized to random values if not set:
-
-* ``SYNAPSE_REGISTRATION_SHARED_SECRET``, secret for registrering users if
-  registration is disable.
-* ``SYNAPSE_MACAROON_SECRET_KEY`` secret for signing access tokens
-  to the server.
-
-Database specific values (will use SQLite if not set):
-
-* `POSTGRES_DB` - The database name for the synapse postgres database. [default: `synapse`]
-* `POSTGRES_HOST` - The host of the postgres database if you wish to use postgresql instead of sqlite3. [default: `db` which is useful when using a container on the same docker network in a compose file where the postgres service is called `db`]
-* `POSTGRES_PASSWORD` - The password for the synapse postgres database. **If this is set then postgres will be used instead of sqlite3.** [default: none] **NOTE**: You are highly encouraged to use postgresql! Please use the compose file to make it easier to deploy.
-* `POSTGRES_USER` - The user for the synapse postgres database. [default: `matrix`]
-
-Mail server specific values (will not send emails if not set):
-
-* ``SYNAPSE_SMTP_HOST``, hostname to the mail server.
-* ``SYNAPSE_SMTP_PORT``, TCP port for accessing the mail server [default ``25``].
-* ``SYNAPSE_SMTP_USER``, username for authenticating against the mail server if any.
-* ``SYNAPSE_SMTP_PASSWORD``, password for authenticating against the mail server if any.

-Support in Synapse for tracking agreement to server terms and conditions
-========================================================================
-
-Synapse 0.30 introduces support for tracking whether users have agreed to the
-terms and conditions set by the administrator of a server - and blocking access
-to the server until they have.
-
-There are several parts to this functionality; each requires some specific
-configuration in `homeserver.yaml` to be enabled.
-
-Note that various parts of the configuation and this document refer to the
-"privacy policy": agreement with a privacy policy is one particular use of this
-feature, but of course adminstrators can specify other terms and conditions
-unrelated to "privacy" per se.
-
-Collecting policy agreement from a user
----------------------------------------
-
-Synapse can be configured to serve the user a simple policy form with an
-"accept" button. Clicking "Accept" records the user's acceptance in the
-database and shows a success page.
-
-To enable this, first create templates for the policy and success pages.
-These should be stored on the local filesystem.
-
-These templates use the [Jinja2](http://jinja.pocoo.org) templating language,
-and [docs/privacy_policy_templates](privacy_policy_templates) gives
-examples of the sort of thing that can be done.
-
-Note that the templates must be stored under a name giving the language of the
-template - currently this must always be `en` (for "English");
-internationalisation support is intended for the future.
-
-The template for the policy itself should be versioned and named according to 
-the version: for example `1.0.html`. The version of the policy which the user
-has agreed to is stored in the database.
-
-Once the templates are in place, make the following changes to `homeserver.yaml`:
-
- 1. Add a `user_consent` section, which should look like:
-
-    ```yaml
-    user_consent:
-      template_dir: privacy_policy_templates
-      version: 1.0
-    ```
-
-    `template_dir` points to the directory containing the policy
-    templates. `version` defines the version of the policy which will be served
-    to the user. In the example above, Synapse will serve
-    `privacy_policy_templates/en/1.0.html`.
-
-
- 2. Add a `form_secret` setting at the top level:
-
-
-    ```yaml
-    form_secret: "<unique secret>"
-    ```
-
-    This should be set to an arbitrary secret string (try `pwgen -y 30` to
-    generate suitable secrets).
-
-    More on what this is used for below.
-
- 3. Add `consent` wherever the `client` resource is currently enabled in the
-    `listeners` configuration. For example:
-
-    ```yaml
-    listeners:
-      - port: 8008
-        resources:
-          - names:
-            - client
-            - consent
-    ```
-
-
-Finally, ensure that `jinja2` is installed. If you are using a virtualenv, this
-should be a matter of `pip install Jinja2`. On debian, try `apt-get install
-python-jinja2`.
-
-Once this is complete, and the server has been restarted, try visiting
-`https://<server>/_matrix/consent`. If correctly configured, this should give
-an error "Missing string query parameter 'u'". It is now possible to manually
-construct URIs where users can give their consent.
-
-### Constructing the consent URI
-
-It may be useful to manually construct the "consent URI" for a given user - for
-instance, in order to send them an email asking them to consent. To do this,
-take the base `https://<server>/_matrix/consent` URL and add the following
-query parameters:
-
- * `u`: the user id of the user. This can either be a full MXID
-   (`@user:server.com`) or just the localpart (`user`).
-
- * `h`: hex-encoded HMAC-SHA256 of `u` using the `form_secret` as a key. It is
-   possible to calculate this on the commandline with something like:
-
-   ```bash
-   echo -n '<user>' | openssl sha256 -hmac '<form_secret>'
-   ```
-
-   This should result in a URI which looks something like:
-   `https://<server>/_matrix/consent?u=<user>&h=68a152465a4d...`.
-
-
-Sending users a server notice asking them to agree to the policy
-----------------------------------------------------------------
-
-It is possible to configure Synapse to send a [server
-notice](server_notices.md) to anybody who has not yet agreed to the current
-version of the policy. To do so:
-
- * ensure that the consent resource is configured, as in the previous section
-
- * ensure that server notices are configured, as in [server_notices.md](server_notices.md).
-
- * Add `server_notice_content` under `user_consent` in `homeserver.yaml`. For
-   example:
-
-   ```yaml
-   user_consent:
-     server_notice_content:
-       msgtype: m.text
-       body: >-
-         Please give your consent to the privacy policy at %(consent_uri)s.
-   ```
-
-   Synapse automatically replaces the placeholder `%(consent_uri)s` with the
-   consent uri for that user.
-
- * ensure that `public_baseurl` is set in `homeserver.yaml`, and gives the base
-   URI that clients use to connect to the server. (It is used to construct
-   `consent_uri` in the server notice.)
-
-
-Blocking users from using the server until they agree to the policy
--------------------------------------------------------------------
-
-Synapse can be configured to block any attempts to join rooms or send messages
-until the user has given their agreement to the policy. (Joining the server
-notices room is exempted from this).
-
-To enable this, add `block_events_error` under `user_consent`. For example:
-
-```yaml
-user_consent:
-  block_events_error: >-
-    You can't send any messages until you consent to the privacy policy at
-    %(consent_uri)s.
-```
-
-Synapse automatically replaces the placeholder `%(consent_uri)s` with the
-consent uri for that user.
-
-ensure that `public_baseurl` is set in `homeserver.yaml`, and gives the base
-URI that clients use to connect to the server. (It is used to construct
-`consent_uri` in the error.)

-Using the synapse manhole
-=========================
-
-The "manhole" allows server administrators to access a Python shell on a running
-Synapse installation. This is a very powerful mechanism for administration and
-debugging.
-
-To enable it, first uncomment the `manhole` listener configuration in
-`homeserver.yaml`:
-
-```yaml
-listeners:
-  - port: 9000
-    bind_addresses: ['::1', '127.0.0.1']
-    type: manhole
-```
-
-(`bind_addresses` in the above is important: it ensures that access to the
-manhole is only possible for local users).
-
-Note that this will give administrative access to synapse to **all users** with
-shell access to the server. It should therefore **not** be enabled in
-environments where untrusted users have shell access.
-
-Then restart synapse, and point an ssh client at port 9000 on localhost, using
-the username `matrix`:
-
-```bash
-ssh -p9000 matrix@localhost
-```
-
-The password is `rabbithole`.
-
-This gives a Python REPL in which `hs` gives access to the
-`synapse.server.HomeServer` object - which in turn gives access to many other
-parts of the process.
-
-As a simple example, retrieving an event from the database:
-
-```

+2. Enable synapse metrics:
 
-   There are two methods of enabling metrics in Synapse.
+   Simply setting a (local) port number will enable it. Pick a port.

+   locally monitored services seems reasonable. E.g. 9092:

-     resources:
-       - names:
-         - client
-         - metrics

-   This provides a simple way of adding metrics to your Synapse installation,
-   and serves under ``/_synapse/metrics``. If you do not wish your metrics be
-   publicly exposed, you will need to either filter it out at your load
-   balancer, or use the second method.
+   Also ensure that ``enable_metrics`` is set to ``True``.
 
-   The second method runs the metrics server on a different port, in a
-   different thread to Synapse. This can make it more resilient to heavy load
-   meaning metrics cannot be retrieved, and can be exposed to just internal
-   networks easier. The served metrics are available over HTTP only, and will
-   be available at ``/``.

-Server Notices
-==============
-
-'Server Notices' are a new feature introduced in Synapse 0.30. They provide a
-channel whereby server administrators can send messages to users on the server.
-
-They are used as part of communication of the server polices(see
-[consent_tracking.md](consent_tracking.md)), however the intention is that
-they may also find a use for features such as "Message of the day".
-
-This is a feature specific to Synapse, but it uses standard Matrix
-communication mechanisms, so should work with any Matrix client.
-
-User experience
----------------
-
-When the user is first sent a server notice, they will get an invitation to a
-room (typically called 'Server Notices', though this is configurable in
-`homeserver.yaml`). They will be **unable to reject** this invitation -
-attempts to do so will receive an error.
-
-Once they accept the invitation, they will see the notice message in the room
-history; it will appear to have come from the 'server notices user' (see
-below).
-
-The user is prevented from sending any messages in this room by the power
-levels.
-
-Having joined the room, the user can leave the room if they want. Subsequent
-server notices will then cause a new room to be created.
-
-Synapse configuration
----------------------
-
-Server notices come from a specific user id on the server. Server
-administrators are free to choose the user id - something like `server` is
-suggested, meaning the notices will come from
-`@server:<your_server_name>`. Once the Server Notices user is configured, that
-user id becomes a special, privileged user, so administrators should ensure
-that **it is not already allocated**.
-
-In order to support server notices, it is necessary to add some configuration
-to the `homeserver.yaml` file. In particular, you should add a `server_notices`
-section, which should look like this:
-
-```yaml
-server_notices:
-   system_mxid_localpart: server
-   system_mxid_display_name: "Server Notices"
-   system_mxid_avatar_url: "mxc://server.com/oumMVlgDnLYFaPVkExemNVVZ"
-   room_name: "Server Notices"
-```
-
-The only compulsory setting is `system_mxid_localpart`, which defines the user
-id of the Server Notices user, as above. `room_name` defines the name of the
-room which will be created.
-
-`system_mxid_display_name` and `system_mxid_avatar_url` can be used to set the
-displayname and avatar of the Server Notices user.
-
-Sending notices
----------------
-
-As of the current version of synapse, there is no convenient interface for
-sending notices (other than the automated ones sent as part of consent
-tracking).
-
-In the meantime, it is possible to test this feature using the manhole. Having
-gone into the manhole as described in [manhole.md](manhole.md), a notice can be
-sent with something like:
-
-```
->>> hs.get_server_notices_manager().send_notice('@user:server.com', {'msgtype':'m.text', 'body':'foo'})
-```

-        (The error will then be logged and sent back to the sender (which
-        probably won't do anything with it), and other events in the
-        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.

-        Raises: FederationError if the signatures / hash do not match, or
