-
-Features
---------
-
-- Changes to 3pid verification:
-  - Add the ability to send registration emails from the homeserver rather than delegating to an identity server. ([\#5835](https://github.com/matrix-org/synapse/issues/5835), [\#5940](https://github.com/matrix-org/synapse/issues/5940), [\#5993](https://github.com/matrix-org/synapse/issues/5993), [\#5994](https://github.com/matrix-org/synapse/issues/5994), [\#5868](https://github.com/matrix-org/synapse/issues/5868))
-  - Replace `trust_identity_server_for_password_resets` config option with `account_threepid_delegates`, and make the `id_server` parameteter optional on `*/requestToken` endpoints, as per [MSC2263](https://github.com/matrix-org/matrix-doc/pull/2263). ([\#5876](https://github.com/matrix-org/synapse/issues/5876), [\#5969](https://github.com/matrix-org/synapse/issues/5969), [\#6028](https://github.com/matrix-org/synapse/issues/6028))
-  - Switch to using the v2 Identity Service `/lookup` API where available, with fallback to v1. (Implements [MSC2134](https://github.com/matrix-org/matrix-doc/pull/2134) plus `id_access_token authentication` for v2 Identity Service APIs from [MSC2140](https://github.com/matrix-org/matrix-doc/pull/2140)). ([\#5897](https://github.com/matrix-org/synapse/issues/5897))
-  - Remove `bind_email` and `bind_msisdn` parameters from `/register` ala [MSC2140](https://github.com/matrix-org/matrix-doc/pull/2140). ([\#5964](https://github.com/matrix-org/synapse/issues/5964))
-  - Add `m.id_access_token` to `unstable_features` in `/versions` as per [MSC2264](https://github.com/matrix-org/matrix-doc/pull/2264). ([\#5974](https://github.com/matrix-org/synapse/issues/5974))
-  - Use the v2 Identity Service API for 3PID invites. ([\#5979](https://github.com/matrix-org/synapse/issues/5979))
-  - Add `POST /_matrix/client/unstable/account/3pid/unbind` endpoint from [MSC2140](https://github.com/matrix-org/matrix-doc/pull/2140) for unbinding a 3PID from an identity server without removing it from the homeserver user account. ([\#5980](https://github.com/matrix-org/synapse/issues/5980), [\#6062](https://github.com/matrix-org/synapse/issues/6062))
-  - Use `account_threepid_delegate.email` and `account_threepid_delegate.msisdn` for validating threepid sessions. ([\#6011](https://github.com/matrix-org/synapse/issues/6011))
-  - Allow homeserver to handle or delegate email validation when adding an email to a user's account. ([\#6042](https://github.com/matrix-org/synapse/issues/6042))
-  - Implement new Client Server API endpoints `/account/3pid/add` and `/account/3pid/bind` as per [MSC2290](https://github.com/matrix-org/matrix-doc/pull/2290). ([\#6043](https://github.com/matrix-org/synapse/issues/6043))
-  - Add an unstable feature flag for separate add/bind 3pid APIs. ([\#6044](https://github.com/matrix-org/synapse/issues/6044))
-  - Remove `bind` parameter from Client Server POST `/account` endpoint as per [MSC2290](https://github.com/matrix-org/matrix-doc/pull/2290/). ([\#6067](https://github.com/matrix-org/synapse/issues/6067))
-  - Add `POST /add_threepid/msisdn/submit_token` endpoint for proxying submitToken on an `account_threepid_handler`. ([\#6078](https://github.com/matrix-org/synapse/issues/6078))
-  - Add `submit_url` response parameter to `*/msisdn/requestToken` endpoints. ([\#6079](https://github.com/matrix-org/synapse/issues/6079))
-  - Add `m.require_identity_server` flag to /version's unstable_features. ([\#5972](https://github.com/matrix-org/synapse/issues/5972))
-- Enhancements to OpenTracing support:
-  - Make OpenTracing work in worker mode. ([\#5771](https://github.com/matrix-org/synapse/issues/5771))
-  - Pass OpenTracing contexts between servers when transmitting EDUs. ([\#5852](https://github.com/matrix-org/synapse/issues/5852))
-  - OpenTracing for device list updates. ([\#5853](https://github.com/matrix-org/synapse/issues/5853))
-  - Add a tag recording a request's authenticated entity and corresponding servlet in OpenTracing. ([\#5856](https://github.com/matrix-org/synapse/issues/5856))
-  - Add minimum OpenTracing for client servlets. ([\#5983](https://github.com/matrix-org/synapse/issues/5983))
-  - Check at setup that OpenTracing is installed if it's enabled in the config. ([\#5985](https://github.com/matrix-org/synapse/issues/5985))
-  - Trace replication send times. ([\#5986](https://github.com/matrix-org/synapse/issues/5986))

-New custom templates
---------------------
-
-If you have configured a custom template directory with the
-``email.template_dir`` option, be aware that there are new templates regarding
-registration and threepid management (see below) that must be included.
-
-* ``registration.html`` and ``registration.txt``
-* ``registration_success.html`` and ``registration_failure.html``
-* ``add_threepid.html`` and  ``add_threepid.txt``
-* ``add_threepid_failure.html`` and ``add_threepid_success.html``
-
-Synapse will expect these files to exist inside the configured template
-directory, and **will fail to start** if they are absent.
-To view the default templates, see `synapse/res/templates
-<https://github.com/matrix-org/synapse/tree/master/synapse/res/templates>`_.
-
-3pid verification changes
--------------------------
-
-**Note: As of this release, users will be unable to add phone numbers or email
-addresses to their accounts, without changes to the Synapse configuration. This
-includes adding an email address during registration.**
-
-It is possible for a user to associate an email address or phone number
-with their account, for a number of reasons:
-
-* for use when logging in, as an alternative to the user id.
-* in the case of email, as an alternative contact to help with account recovery.
-* in the case of email, to receive notifications of missed messages.
-
-Before an email address or phone number can be added to a user's account,
-or before such an address is used to carry out a password-reset, Synapse must
-confirm the operation with the owner of the email address or phone number.
-It does this by sending an email or text giving the user a link or token to confirm
-receipt. This process is known as '3pid verification'. ('3pid', or 'threepid',
-stands for third-party identifier, and we use it to refer to external
-identifiers such as email addresses and phone numbers.)
-
-Previous versions of Synapse delegated the task of 3pid verification to an
-identity server by default. In most cases this server is ``vector.im`` or
-``matrix.org``.
-
-In Synapse 1.4.0, for security and privacy reasons, the homeserver will no
-longer delegate this task to an identity server by default. Instead,
-the server administrator will need to explicitly decide how they would like the
-verification messages to be sent.
-
-In the medium term, the ``vector.im`` and ``matrix.org`` identity servers will
-disable support for delegated 3pid verification entirely. However, in order to
-ease the transition, they will retain the capability for a limited
-period. Delegated email verification will be disabled on Monday 2nd December
-2019 (giving roughly 2 months notice). Disabling delegated SMS verification
-will follow some time after that once SMS verification support lands in
-Synapse.
-
-Once delegated 3pid verification support has been disabled in the ``vector.im`` and
-``matrix.org`` identity servers, all Synapse versions that depend on those
-instances will be unable to verify email and phone numbers through them. There
-are no imminent plans to remove delegated 3pid verification from Sydent
-generally. (Sydent is the identity server project that backs the ``vector.im`` and
-``matrix.org`` instances).
-
-Email
-~~~~~
-Following upgrade, to continue verifying email (e.g. as part of the
-registration process), admins can either:-
-
-* Configure Synapse to use an email server.
-* Run or choose an identity server which allows delegated email verification
-  and delegate to it.
-
-Configure SMTP in Synapse
-+++++++++++++++++++++++++
-
-To configure an SMTP server for Synapse, modify the configuration section
-headed ``email``, and be sure to have at least the ``smtp_host, smtp_port``
-and ``notif_from`` fields filled out.
-
-You may also need to set ``smtp_user``, ``smtp_pass``, and
-``require_transport_security``.
-
-See the `sample configuration file <docs/sample_config.yaml>`_ for more details
-on these settings.
-
-Delegate email to an identity server
-++++++++++++++++++++++++++++++++++++
-
-Some admins will wish to continue using email verification as part of the
-registration process, but will not immediately have an appropriate SMTP server
-at hand.
-
-To this end, we will continue to support email verification delegation via the
-``vector.im`` and ``matrix.org`` identity servers for two months. Support for
-delegated email verification will be disabled on Monday 2nd December.
-
-The ``account_threepid_delegates`` dictionary defines whether the homeserver
-should delegate an external server (typically an `identity server
-<https://matrix.org/docs/spec/identity_service/r0.2.1>`_) to handle sending
-confirmation messages via email and SMS.
-
-So to delegate email verification, in ``homeserver.yaml``, set
-``account_threepid_delegates.email`` to the base URL of an identity server. For
-example:
-
-.. code:: yaml
-
-   account_threepid_delegates:
-       email: https://example.com     # Delegate email sending to example.com
-
-Note that ``account_threepid_delegates.email`` replaces the deprecated
-``email.trust_identity_server_for_password_resets``: if
-``email.trust_identity_server_for_password_resets`` is set to ``true``, and
-``account_threepid_delegates.email`` is not set, then the first entry in
-``trusted_third_party_id_servers`` will be used as the
-``account_threepid_delegate`` for email. This is to ensure compatibility with
-existing Synapse installs that set up external server handling for these tasks
-before v1.4.0. If ``email.trust_identity_server_for_password_resets`` is
-``true`` and no trusted identity server domains are configured, Synapse will
-report an error and refuse to start.
-
-If ``email.trust_identity_server_for_password_resets`` is ``false`` or absent
-and no ``email`` delegate is configured in ``account_threepid_delegates``,
-then Synapse will send email verification messages itself, using the configured
-SMTP server (see above).
-that type.
-
-Phone numbers
-~~~~~~~~~~~~~
-
-Synapse does not support phone-number verification itself, so the only way to
-maintain the ability for users to add phone numbers to their accounts will be
-by continuing to delegate phone number verification to the ``matrix.org`` and
-``vector.im`` identity servers (or another identity server that supports SMS
-sending).
-
-The ``account_threepid_delegates`` dictionary defines whether the homeserver
-should delegate an external server (typically an `identity server
-<https://matrix.org/docs/spec/identity_service/r0.2.1>`_) to handle sending
-confirmation messages via email and SMS.
-
-So to delegate phone number verification, in ``homeserver.yaml``, set
-``account_threepid_delegates.msisdn`` to the base URL of an identity
-server. For example:
-
-.. code:: yaml
-
-   account_threepid_delegates:
-       msisdn: https://example.com     # Delegate sms sending to example.com
-
-The ``matrix.org`` and ``vector.im`` identity servers will continue to support
-delegated phone number verification via SMS until such time as it is possible
-for admins to configure their servers to perform phone number verification
-directly. More details will follow in a future release.
-
-Rolling back to v1.3.1
-----------------------
-
-If you encounter problems with v1.4.0, it should be possible to roll back to
-v1.3.1, subject to the following:
-
-* The 'room statistics' engine was heavily reworked in this release (see
-  `#5971 <https://github.com/matrix-org/synapse/pull/5971>`_), including
-  significant changes to the database schema, which are not easily
-  reverted. This will cause the room statistics engine to stop updating when
-  you downgrade.
-
-  The room statistics are essentially unused in v1.3.1 (in future versions of
-  Synapse, they will be used to populate the room directory), so there should
-  be no loss of functionality. However, the statistics engine will write errors
-  to the logs, which can be avoided by setting the following in
-  `homeserver.yaml`:
-
-  .. code:: yaml
-
-    stats:
-      enabled: false
-
-  Don't forget to re-enable it when you upgrade again, in preparation for its
-  use in the room directory!
+    # replace <host.name> with the hostname of your synapse homeserver.
+    # You may need to specify a port (eg, :8448) if your server is not
+    # configured on port 443.

-### Configuration
+FIXME: this is out-of-date as of
+https://github.com/matrix-org/synapse/issues/5518. Contributions to bring it up
+to date would be welcome.
+
+### 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`, you can use the `generate` command.
-(See the [documentation](../../docker/README.md#generating-a-configuration-file)
-for more information.) You will need to specify appropriate values for at least the
-`SYNAPSE_SERVER_NAME` and `SYNAPSE_REPORT_STATS` environment variables. For example:
+to use manual configuration. To generate a fresh ``homeserver.yaml``, simply run:
 
 ```
-docker-compose run --rm -e SYNAPSE_SERVER_NAME=my.matrix.host -e SYNAPSE_REPORT_STATS=yes synapse generate
+docker-compose run --rm -e SYNAPSE_SERVER_NAME=my.matrix.host synapse generate
 ```
 
-(This will also generate necessary signing keys.)
-
 Then, customize your configuration and run the server:

-# Server to Server
-
-## Server to Server Stack
-
-To use the server to server stack, home servers should only need to
-interact with the Messaging layer.
-
-The server to server side of things is designed into 4 distinct layers:
-
-1.  Messaging Layer
-2.  Pdu Layer
-3.  Transaction Layer
-4.  Transport Layer
-
-Where the bottom (the transport layer) is what talks to the internet via
-HTTP, and the top (the messaging layer) talks to the rest of the Home
-Server with a domain specific API.
-
-1. **Messaging Layer**
-
-    This is what the rest of the Home Server hits to send messages, join rooms,
-    etc. It also allows you to register callbacks for when it get's notified by
-    lower levels that e.g. a new message has been received.
-
-    It is responsible for serializing requests to send to the data
-    layer, and to parse requests received from the data layer.
-
-2. **PDU Layer**
-
-    This layer handles:
-
-		- duplicate `pdu_id`'s - i.e., it makes sure we ignore them.
-		- responding to requests for a given `pdu_id`
-		- responding to requests for all metadata for a given context (i.e. room)
-		- handling incoming backfill requests
-
-		So it has to parse incoming messages to discover which are metadata and
-    which aren't, and has to correctly clobber existing metadata where
-    appropriate.
-
-    For incoming PDUs, it has to check the PDUs it references to see
-    if we have missed any. If we have go and ask someone (another
-    home server) for it.
-
-3. **Transaction Layer**
-
-		This layer makes incoming requests idempotent. i.e., it stores
-		which transaction id's we have seen and what our response were.
-		If we have already seen a message with the given transaction id,
-		we do not notify higher levels but simply respond with the
-		previous response.
-
-		`transaction_id` is from "`GET /send/<tx_id>/`"
-
-		It's also responsible for batching PDUs into single transaction for
-		sending to remote destinations, so that we only ever have one
-		transaction in flight to a given destination at any one time.
-
-		This is also responsible for answering requests for things after a
-		given set of transactions, i.e., ask for everything after 'ver' X.
-
-4. **Transport Layer**
-
-		This is responsible for starting a HTTP server and hitting the
-		correct callbacks on the Transaction layer, as well as sending
-		both data and requests for data.
-
-## Persistence
-
-We persist things in a single sqlite3 database. All database queries get
-run on a separate, dedicated thread. This that we only ever have one
-query running at a time, making it a lot easier to do things in a safe
-manner.
-
-The queries are located in the `synapse.persistence.transactions` module,
-and the table information in the `synapse.persistence.tables` module.

-        -   auth(event)
-        -   persist_event(event)
-        -   notify notifier or federation(event)

-        Very lightweight logic built on the distributor
-    -   TypingHandler: use distributor to get EDUs out of Federation.
-        Very lightweight logic built on the distributor
-    -   EventsHandler: handles the events stream...
-    -   FederationHandler: - gets PDU from Federation Layer; turns into
-        an event; follows basehandler functionality.
-    -   RoomsHandler: does all the room logic, including members - lots
-        of classes in RoomsHandler.
-    -   ProfileHandler: talks to the storage to store/retrieve profile
-        info.
--   EventFactory: generates events of particular event types.
--   Notifier: Backs the events handler
--   REST: Interfaces handlers and events to the outside world via
-    HTTP/JSON. Converts events back and forth from JSON.
--   Federation: holds the HTTP client & server to talk to other servers.
-    Does replication to make sure there's nothing missing in the graph.
-    Handles reliability. Handles txns.
--   Distributor: generic event bus. used for presence & typing only
-    currently. Notifier could be implemented using Distributor - so far
-    we are only using for things which actually /require/ dynamic
-    pluggability however as it can obfuscate the actual flow of control.

+
+* EventFactory: generates events of particular event types.
+* Notifier: Backs the events handler
+* REST: Interfaces handlers and events to the outside world via HTTP/JSON.
+  Converts events back and forth from JSON.
+* Federation: holds the HTTP client & server to talk to other servers.  Does
+  replication to make sure there's nothing missing in the graph.  Handles

+* Distributor: generic event bus. used for presence & typing only currently. 
+  Notifier could be implemented using Distributor - so far we are only using for
+  things which actually /require/ dynamic pluggability however as it can

-## Formatting tools
-
-The Synapse codebase uses a number of code formatting tools in order to
-quickly and automatically check for formatting (and sometimes logical)
-errors in code.
-
-The necessary tools are detailed below.
-
--   **black**
-
-    The Synapse codebase uses [black](https://pypi.org/project/black/)
-    as an opinionated code formatter, ensuring all comitted code is
-    properly formatted.
-
-    First install `black` with:
-
-        pip install --upgrade black
-
-    Have `black` auto-format your code (it shouldn't change any
-    functionality) with:
-
-        black . --exclude="\.tox|build|env"
-
--   **flake8**
-
-    `flake8` is a code checking tool. We require code to pass `flake8`
-    before being merged into the codebase.
-
-    Install `flake8` with:
-
-        pip install --upgrade flake8
-
-    Check all application and test code with:
-
-        flake8 synapse tests
-
--   **isort**
-
-    `isort` ensures imports are nicely formatted, and can suggest and
-    auto-fix issues such as double-importing.
-
-    Install `isort` with:
-
-        pip install --upgrade isort
-
-    Auto-fix imports with:
-
-        isort -rc synapse tests
-
-    `-rc` means to recursively search the given directories.
-
-It's worth noting that modern IDEs and text editors can run these tools
-automatically on save. It may be worth looking into whether this
-functionality is supported in your editor for a more convenient
-development workflow. It is not, however, recommended to run `flake8` on
-save as it takes a while and is very resource intensive.
-
-## General rules
-
--   **Naming**:
-    -   Use camel case for class and type names
-    -   Use underscores for functions and variables.
--   **Docstrings**: should follow the [google code
-    style](https://google.github.io/styleguide/pyguide.html#38-comments-and-docstrings).
-    This is so that we can generate documentation with
-    [sphinx](http://sphinxcontrib-napoleon.readthedocs.org/en/latest/).
-    See the
-    [examples](http://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_google.html)
-    in the sphinx documentation.
--   **Imports**:
-    -   Imports should be sorted by `isort` as described above.
-    -   Prefer to import classes and functions rather than packages or
-        modules.
-
-        Example:
-
-            from synapse.types import UserID
-            ...
-            user_id = UserID(local, server)
-
-        is preferred over:
-
-            from synapse import types
-            ...
-            user_id = types.UserID(local, server)
-
-        (or any other variant).
-
-        This goes against the advice in the Google style guide, but it
-        means that errors in the name are caught early (at import time).
-
-    -   Avoid wildcard imports (`from synapse.types import *`) and
-        relative imports (`from .types import UserID`).
-
-## Configuration file format
-
-The [sample configuration file](./sample_config.yaml) acts as a
-reference to Synapse's configuration options for server administrators.
-Remember that many readers will be unfamiliar with YAML and server
-administration in general, so that it is important that the file be as
-easy to understand as possible, which includes following a consistent
-format.
-
-Some guidelines follow:
-
--   Sections should be separated with a heading consisting of a single
-    line prefixed and suffixed with `##`. There should be **two** blank
-    lines before the section header, and **one** after.
--   Each option should be listed in the file with the following format:
-    -   A comment describing the setting. Each line of this comment
-        should be prefixed with a hash (`#`) and a space.
-
-        The comment should describe the default behaviour (ie, what
-        happens if the setting is omitted), as well as what the effect
-        will be if the setting is changed.
-
-        Often, the comment end with something like "uncomment the
-        following to <do action>".
-
-    -   A line consisting of only `#`.
-    -   A commented-out example setting, prefixed with only `#`.
-
-        For boolean (on/off) options, convention is that this example
-        should be the *opposite* to the default (so the comment will end
-        with "Uncomment the following to enable [or disable]
-        <feature>." For other options, the example should give some
-        non-default value which is likely to be useful to the reader.
-
--   There should be a blank line between each option.
--   Where several settings are grouped into a single dict, *avoid* the
-    convention where the whole block is commented out, resulting in
-    comment lines starting `# #`, as this is hard to read and confusing
-    to edit. Instead, leave the top-level config option uncommented, and
-    follow the conventions above for sub-options. Ensure that your code
-    correctly handles the top-level option being set to `None` (as it
-    will be if no sub-options are enabled).
--   Lines should be wrapped at 80 characters.
-
-Example:
-
-    ## Frobnication ##
-
-    # The frobnicator will ensure that all requests are fully frobnicated.
-    # To enable it, uncomment the following.
-    #
-    #frobnicator_enabled: true
-
-    # By default, the frobnicator will frobnicate with the default frobber.
-    # The following will make it use an alternative frobber.
-    #
-    #frobincator_frobber: special_frobber
-
-    # Settings for the frobber
-    #
-    frobber:
-       # frobbing speed. Defaults to 1.
-       #
-       #speed: 10
-
-       # frobbing distance. Defaults to 1000.
-       #
-       #distance: 100
-
-Note that the sample configuration is generated from the synapse code
-and is maintained by a script, `scripts-dev/generate_sample_config`.

-deploy and configure a complicated software stack.
-
-To make Synapse (and therefore Riot) use it:
-
-1. Use the samling.html URL above or deploy your own and visit the IdP Metadata tab.
-2. Copy the XML to your clipboard.
-3. On your Synapse server, create a new file `samling.xml` next to your `homeserver.yaml` with
-   the XML from step 2 as the contents.
-4. Edit your `homeserver.yaml` to include:

-       metadata:
-         local: ["samling.xml"]   
-   ```
-5. Run `apt-get install xmlsec1` and `pip install --upgrade --force 'pysaml2>=4.5.0'` to ensure
-   the dependencies are installed and ready to go.
-6. Restart Synapse.
-
-Then in Riot:
-
-1. Visit the login page with a Riot pointing at your homeserver.
-2. Click the Single Sign-On button.
-3. On the samling page, enter a Name Identifier and add a SAML Attribute for `uid=your_localpart`.
-   The response must also be signed.
-4. Click "Next".
-5. Click "Post Response" (change nothing).
-6. You should be logged in.
-
-If you try and repeat this process, you may be automatically logged in using the information you
-gave previously. To fix this, open your developer console (`F12` or `Ctrl+Shift+I`) while on the
-samling page and clear the site data. In Chrome, this will be a button on the Application tab.

-# Log Contexts
-
-To help track the processing of individual requests, synapse uses a
-'`log context`' to track which request it is handling at any given
-moment. This is done via a thread-local variable; a `logging.Filter` is
-then used to fish the information back out of the thread-local variable
-and add it to each log record.
-
-Logcontexts are also used for CPU and database accounting, so that we
-can track which requests were responsible for high CPU use or database
-activity.
-
-The `synapse.logging.context` module provides a facilities for managing
-the current log context (as well as providing the `LoggingContextFilter`
-class).
-
-Deferreds make the whole thing complicated, so this document describes
-how it all works, and how to write code which follows the rules.
-
-##Logcontexts without Deferreds
-
-In the absence of any Deferred voodoo, things are simple enough. As with
-any code of this nature, the rule is that our function should leave
-things as it found them:
-
-```python
-from synapse.logging import context         # omitted from future snippets
-
-def handle_request(request_id):
-    request_context = context.LoggingContext()
-
-    calling_context = context.LoggingContext.current_context()
-    context.LoggingContext.set_current_context(request_context)
-    try:
-        request_context.request = request_id
-        do_request_handling()
-        logger.debug("finished")
-    finally:
-        context.LoggingContext.set_current_context(calling_context)
-
-def do_request_handling():
-    logger.debug("phew")  # this will be logged against request_id
-```
-
-LoggingContext implements the context management methods, so the above
-can be written much more succinctly as:
-
-```python
-def handle_request(request_id):
-    with context.LoggingContext() as request_context:
-        request_context.request = request_id
-        do_request_handling()
-        logger.debug("finished")
-
-def do_request_handling():
-    logger.debug("phew")
-```
-
-## Using logcontexts with Deferreds
-
-Deferreds --- and in particular, `defer.inlineCallbacks` --- break the
-linear flow of code so that there is no longer a single entry point
-where we should set the logcontext and a single exit point where we
-should remove it.
-
-Consider the example above, where `do_request_handling` needs to do some
-blocking operation, and returns a deferred:
-
-```python
-@defer.inlineCallbacks
-def handle_request(request_id):
-    with context.LoggingContext() as request_context:
-        request_context.request = request_id
-        yield do_request_handling()
-        logger.debug("finished")
-```
-
-In the above flow:
-
--   The logcontext is set
--   `do_request_handling` is called, and returns a deferred
--   `handle_request` yields the deferred
--   The `inlineCallbacks` wrapper of `handle_request` returns a deferred
-
-So we have stopped processing the request (and will probably go on to
-start processing the next), without clearing the logcontext.
-
-To circumvent this problem, synapse code assumes that, wherever you have
-a deferred, you will want to yield on it. To that end, whereever
-functions return a deferred, we adopt the following conventions:
-
-**Rules for functions returning deferreds:**
-
-> -   If the deferred is already complete, the function returns with the
->     same logcontext it started with.
-> -   If the deferred is incomplete, the function clears the logcontext
->     before returning; when the deferred completes, it restores the
->     logcontext before running any callbacks.
-
-That sounds complicated, but actually it means a lot of code (including
-the example above) "just works". There are two cases:
-
--   If `do_request_handling` returns a completed deferred, then the
-    logcontext will still be in place. In this case, execution will
-    continue immediately after the `yield`; the "finished" line will
-    be logged against the right context, and the `with` block restores
-    the original context before we return to the caller.
--   If the returned deferred is incomplete, `do_request_handling` clears
-    the logcontext before returning. The logcontext is therefore clear
-    when `handle_request` yields the deferred. At that point, the
-    `inlineCallbacks` wrapper adds a callback to the deferred, and
-    returns another (incomplete) deferred to the caller, and it is safe
-    to begin processing the next request.
-
-    Once `do_request_handling`'s deferred completes, it will reinstate
-    the logcontext, before running the callback added by the
-    `inlineCallbacks` wrapper. That callback runs the second half of
-    `handle_request`, so again the "finished" line will be logged
-    against the right context, and the `with` block restores the
-    original context.
-
-As an aside, it's worth noting that `handle_request` follows our rules
--though that only matters if the caller has its own logcontext which it
-cares about.
-
-The following sections describe pitfalls and helpful patterns when
-implementing these rules.
-
-Always yield your deferreds
----------------------------
-
-Whenever you get a deferred back from a function, you should `yield` on
-it as soon as possible. (Returning it directly to your caller is ok too,
-if you're not doing `inlineCallbacks`.) Do not pass go; do not do any
-logging; do not call any other functions.
-
-```python
-@defer.inlineCallbacks
-def fun():
-    logger.debug("starting")
-    yield do_some_stuff()       # just like this
-
-    d = more_stuff()
-    result = yield d            # also fine, of course
-
-    return result
-
-def nonInlineCallbacksFun():
-    logger.debug("just a wrapper really")
-    return do_some_stuff()      # this is ok too - the caller will yield on
-                                # it anyway.
-```
-
-Provided this pattern is followed all the way back up to the callchain
-to where the logcontext was set, this will make things work out ok:
-provided `do_some_stuff` and `more_stuff` follow the rules above, then
-so will `fun` (as wrapped by `inlineCallbacks`) and
-`nonInlineCallbacksFun`.
-
-It's all too easy to forget to `yield`: for instance if we forgot that
-`do_some_stuff` returned a deferred, we might plough on regardless. This
-leads to a mess; it will probably work itself out eventually, but not
-before a load of stuff has been logged against the wrong context.
-(Normally, other things will break, more obviously, if you forget to
-`yield`, so this tends not to be a major problem in practice.)
-
-Of course sometimes you need to do something a bit fancier with your
-Deferreds - not all code follows the linear A-then-B-then-C pattern.
-Notes on implementing more complex patterns are in later sections.
-
-## Where you create a new Deferred, make it follow the rules
-
-Most of the time, a Deferred comes from another synapse function.
-Sometimes, though, we need to make up a new Deferred, or we get a
-Deferred back from external code. We need to make it follow our rules.
-
-The easy way to do it is with a combination of `defer.inlineCallbacks`,
-and `context.PreserveLoggingContext`. Suppose we want to implement
-`sleep`, which returns a deferred which will run its callbacks after a
-given number of seconds. That might look like:
-
-```python
-# not a logcontext-rules-compliant function
-def get_sleep_deferred(seconds):
-    d = defer.Deferred()
-    reactor.callLater(seconds, d.callback, None)
-    return d
-```
-
-That doesn't follow the rules, but we can fix it by wrapping it with
-`PreserveLoggingContext` and `yield` ing on it:
-
-```python
-@defer.inlineCallbacks
-def sleep(seconds):
-    with PreserveLoggingContext():
-        yield get_sleep_deferred(seconds)
-```
-
-This technique works equally for external functions which return
-deferreds, or deferreds we have made ourselves.
-
-You can also use `context.make_deferred_yieldable`, which just does the
-boilerplate for you, so the above could be written:
-
-```python
-def sleep(seconds):
-    return context.make_deferred_yieldable(get_sleep_deferred(seconds))
-```
-
-## Fire-and-forget
-
-Sometimes you want to fire off a chain of execution, but not wait for
-its result. That might look a bit like this:
-
-```python
-@defer.inlineCallbacks
-def do_request_handling():
-    yield foreground_operation()
-
-    # *don't* do this
-    background_operation()
-
-    logger.debug("Request handling complete")
-
-@defer.inlineCallbacks
-def background_operation():
-    yield first_background_step()
-    logger.debug("Completed first step")
-    yield second_background_step()
-    logger.debug("Completed second step")
-```
-
-The above code does a couple of steps in the background after
-`do_request_handling` has finished. The log lines are still logged
-against the `request_context` logcontext, which may or may not be
-desirable. There are two big problems with the above, however. The first
-problem is that, if `background_operation` returns an incomplete
-Deferred, it will expect its caller to `yield` immediately, so will have
-cleared the logcontext. In this example, that means that 'Request
-handling complete' will be logged without any context.
-
-The second problem, which is potentially even worse, is that when the
-Deferred returned by `background_operation` completes, it will restore
-the original logcontext. There is nothing waiting on that Deferred, so
-the logcontext will leak into the reactor and possibly get attached to
-some arbitrary future operation.
-
-There are two potential solutions to this.
-
-One option is to surround the call to `background_operation` with a
-`PreserveLoggingContext` call. That will reset the logcontext before
-starting `background_operation` (so the context restored when the
-deferred completes will be the empty logcontext), and will restore the
-current logcontext before continuing the foreground process:
-
-```python
-@defer.inlineCallbacks
-def do_request_handling():
-    yield foreground_operation()
-
-    # start background_operation off in the empty logcontext, to
-    # avoid leaking the current context into the reactor.
-    with PreserveLoggingContext():
-        background_operation()
-
-    # this will now be logged against the request context
-    logger.debug("Request handling complete")
-```
-
-Obviously that option means that the operations done in
-`background_operation` would be not be logged against a logcontext
-(though that might be fixed by setting a different logcontext via a
-`with LoggingContext(...)` in `background_operation`).
-
-The second option is to use `context.run_in_background`, which wraps a
-function so that it doesn't reset the logcontext even when it returns
-an incomplete deferred, and adds a callback to the returned deferred to
-reset the logcontext. In other words, it turns a function that follows
-the Synapse rules about logcontexts and Deferreds into one which behaves
-more like an external function --- the opposite operation to that
-described in the previous section. It can be used like this:
-
-```python
-@defer.inlineCallbacks
-def do_request_handling():
-    yield foreground_operation()
-
-    context.run_in_background(background_operation)
-
-    # this will now be logged against the request context
-    logger.debug("Request handling complete")
-```
-
-## Passing synapse deferreds into third-party functions
-
-A typical example of this is where we want to collect together two or
-more deferred via `defer.gatherResults`:
-
-```python
-d1 = operation1()
-d2 = operation2()
-d3 = defer.gatherResults([d1, d2])
-```
-
-This is really a variation of the fire-and-forget problem above, in that
-we are firing off `d1` and `d2` without yielding on them. The difference
-is that we now have third-party code attached to their callbacks. Anyway
-either technique given in the [Fire-and-forget](#fire-and-forget)
-section will work.
-
-Of course, the new Deferred returned by `gatherResults` needs to be
-wrapped in order to make it follow the logcontext rules before we can
-yield it, as described in [Where you create a new Deferred, make it
-follow the
-rules](#where-you-create-a-new-deferred-make-it-follow-the-rules).
-
-So, option one: reset the logcontext before starting the operations to
-be gathered:
-
-```python
-@defer.inlineCallbacks
-def do_request_handling():
-    with PreserveLoggingContext():
-        d1 = operation1()
-        d2 = operation2()
-        result = yield defer.gatherResults([d1, d2])
-```
-
-In this case particularly, though, option two, of using
-`context.preserve_fn` almost certainly makes more sense, so that
-`operation1` and `operation2` are both logged against the original
-logcontext. This looks like:
-
-```python
-@defer.inlineCallbacks
-def do_request_handling():
-    d1 = context.preserve_fn(operation1)()
-    d2 = context.preserve_fn(operation2)()
-
-    with PreserveLoggingContext():
-        result = yield defer.gatherResults([d1, d2])
-```
-
-## Was all this really necessary?
-
-The conventions used work fine for a linear flow where everything
-happens in series via `defer.inlineCallbacks` and `yield`, but are
-certainly tricky to follow for any more exotic flows. It's hard not to
-wonder if we could have done something else.
-
-We're not going to rewrite Synapse now, so the following is entirely of
-academic interest, but I'd like to record some thoughts on an
-alternative approach.
-
-I briefly prototyped some code following an alternative set of rules. I
-think it would work, but I certainly didn't get as far as thinking how
-it would interact with concepts as complicated as the cache descriptors.
-
-My alternative rules were:
-
--   functions always preserve the logcontext of their caller, whether or
-    not they are returning a Deferred.
--   Deferreds returned by synapse functions run their callbacks in the
-    same context as the function was orignally called in.
-
-The main point of this scheme is that everywhere that sets the
-logcontext is responsible for clearing it before returning control to
-the reactor.
-
-So, for example, if you were the function which started a
-`with LoggingContext` block, you wouldn't `yield` within it --- instead
-you'd start off the background process, and then leave the `with` block
-to wait for it:
-
-```python
-def handle_request(request_id):
-    with context.LoggingContext() as request_context:
-        request_context.request = request_id
-        d = do_request_handling()
-
-    def cb(r):
-        logger.debug("finished")
-
-    d.addCallback(cb)
-    return d
-```
-
-(in general, mixing `with LoggingContext` blocks and
-`defer.inlineCallbacks` in the same function leads to slighly
-counter-intuitive code, under this scheme).
-
-Because we leave the original `with` block as soon as the Deferred is
-returned (as opposed to waiting for it to be resolved, as we do today),
-the logcontext is cleared before control passes back to the reactor; so
-if there is some code within `do_request_handling` which needs to wait
-for a Deferred to complete, there is no need for it to worry about
-clearing the logcontext before doing so:
-
-```python
-def handle_request():
-    r = do_some_stuff()
-    r.addCallback(do_some_more_stuff)
-    return r
-```
-
---- and provided `do_some_stuff` follows the rules of returning a
-Deferred which runs its callbacks in the original logcontext, all is
-happy.
-
-The business of a Deferred which runs its callbacks in the original
-logcontext isn't hard to achieve --- we have it today, in the shape of
-`context._PreservingContextDeferred`:
-
-```python
-def do_some_stuff():
-    deferred = do_some_io()
-    pcd = _PreservingContextDeferred(LoggingContext.current_context())
-    deferred.chainDeferred(pcd)
-    return pcd
-```
-
-It turns out that, thanks to the way that Deferreds chain together, we
-automatically get the property of a context-preserving deferred with
-`defer.inlineCallbacks`, provided the final Defered the function
-`yields` on has that property. So we can just write:
-
-```python
-@defer.inlineCallbacks
-def handle_request():
-    yield do_some_stuff()
-    yield do_some_more_stuff()
-```
-
-To conclude: I think this scheme would have worked equally well, with
-less danger of messing it up, and probably made some more esoteric code
-easier to write. But again --- changing the conventions of the entire
-Synapse codebase is not a sensible option for the marginal improvement
-offered.
-
-## A note on garbage-collection of Deferred chains
-
-It turns out that our logcontext rules do not play nicely with Deferred
-chains which get orphaned and garbage-collected.
-
-Imagine we have some code that looks like this:
-
-```python
-listener_queue = []
-
-def on_something_interesting():
-    for d in listener_queue:
-        d.callback("foo")
-
-@defer.inlineCallbacks
-def await_something_interesting():
-    new_deferred = defer.Deferred()
-    listener_queue.append(new_deferred)
-
-    with PreserveLoggingContext():
-        yield new_deferred
-```
-
-Obviously, the idea here is that we have a bunch of things which are
-waiting for an event. (It's just an example of the problem here, but a
-relatively common one.)
-
-Now let's imagine two further things happen. First of all, whatever was
-waiting for the interesting thing goes away. (Perhaps the request times
-out, or something *even more* interesting happens.)
-
-Secondly, let's suppose that we decide that the interesting thing is
-never going to happen, and we reset the listener queue:
-
-```python
-def reset_listener_queue():
-    listener_queue.clear()
-```
-
-So, both ends of the deferred chain have now dropped their references,
-and the deferred chain is now orphaned, and will be garbage-collected at
-some point. Note that `await_something_interesting` is a generator
-function, and when Python garbage-collects generator functions, it gives
-them a chance to clean up by making the `yield` raise a `GeneratorExit`
-exception. In our case, that means that the `__exit__` handler of
-`PreserveLoggingContext` will carefully restore the request context, but
-there is now nothing waiting for its return, so the request context is
-never cleared.
-
-To reiterate, this problem only arises when *both* ends of a deferred
-chain are dropped. Dropping the the reference to a deferred you're
-supposed to be calling is probably bad practice, so this doesn't
-actually happen too much. Unfortunately, when it does happen, it will
-lead to leaked logcontexts which are incredibly hard to track down.
