Synapse 1.3.0 (2019-08-15)

Browse Source 
==========================
 
 Bugfixes
 --------
 
 - Fix 500 Internal Server Error on `publicRooms` when the public room list was
   cached. ([\#5851](https://github.com/matrix-org/synapse/issues/5851))
 
 Synapse 1.3.0rc1 (2019-08-13)
 ==========================
 
 Features
 --------
 
 - Use `M_USER_DEACTIVATED` instead of `M_UNKNOWN` for errcode when a deactivated user attempts to login. ([\#5686](https://github.com/matrix-org/synapse/issues/5686))
 - Add sd_notify hooks to ease systemd integration and allows usage of Type=Notify. ([\#5732](https://github.com/matrix-org/synapse/issues/5732))
 - Synapse will no longer serve any media repo admin endpoints when `enable_media_repo` is set to False in the configuration. If a media repo worker is used, the admin APIs relating to the media repo will be served from it instead. ([\#5754](https://github.com/matrix-org/synapse/issues/5754), [\#5848](https://github.com/matrix-org/synapse/issues/5848))
 - Synapse can now be configured to not join remote rooms of a given "complexity" (currently, state events) over federation. This option can be used to prevent adverse performance on resource-constrained homeservers. ([\#5783](https://github.com/matrix-org/synapse/issues/5783))
 - Allow defining HTML templates to serve the user on account renewal attempt when using the account validity feature. ([\#5807](https://github.com/matrix-org/synapse/issues/5807))
 
 Bugfixes
 --------
 
 - Fix UISIs during homeserver outage. ([\#5693](https://github.com/matrix-org/synapse/issues/5693), [\#5789](https://github.com/matrix-org/synapse/issues/5789))
 - Fix stack overflow in server key lookup code. ([\#5724](https://github.com/matrix-org/synapse/issues/5724))
 - start.sh no longer uses deprecated cli option. ([\#5725](https://github.com/matrix-org/synapse/issues/5725))
 - Log when we receive an event receipt from an unexpected origin. ([\#5743](https://github.com/matrix-org/synapse/issues/5743))
 - Fix debian packaging scripts to correctly build sid packages. ([\#5775](https://github.com/matrix-org/synapse/issues/5775))
 - Correctly handle redactions of redactions. ([\#5788](https://github.com/matrix-org/synapse/issues/5788))
 - Return 404 instead of 403 when accessing /rooms/{roomId}/event/{eventId} for an event without the appropriate permissions. ([\#5798](https://github.com/matrix-org/synapse/issues/5798))
 - Fix check that tombstone is a state event in push rules. ([\#5804](https://github.com/matrix-org/synapse/issues/5804))
 - Fix error when trying to login as a deactivated user when using a worker to handle login. ([\#5806](https://github.com/matrix-org/synapse/issues/5806))
 - Fix bug where user `/sync` stream could get wedged in rare circumstances. ([\#5825](https://github.com/matrix-org/synapse/issues/5825))
 - The purge_remote_media.sh script was fixed. ([\#5839](https://github.com/matrix-org/synapse/issues/5839))
 
 Deprecations and Removals
 -------------------------
 
 - Synapse now no longer accepts the `-v`/`--verbose`, `-f`/`--log-file`, or `--log-config` command line flags, and removes the deprecated `verbose` and `log_file` configuration file options. Users of these options should migrate their options into the dedicated log configuration. ([\#5678](https://github.com/matrix-org/synapse/issues/5678), [\#5729](https://github.com/matrix-org/synapse/issues/5729))
 - Remove non-functional 'expire_access_token' setting. ([\#5782](https://github.com/matrix-org/synapse/issues/5782))
 
 Internal Changes
 ----------------
 
 - Make Jaeger fully configurable. ([\#5694](https://github.com/matrix-org/synapse/issues/5694))
 - Add precautionary measures to prevent future abuse of `window.opener` in default welcome page. ([\#5695](https://github.com/matrix-org/synapse/issues/5695))
 - Reduce database IO usage by optimising queries for current membership. ([\#5706](https://github.com/matrix-org/synapse/issues/5706), [\#5738](https://github.com/matrix-org/synapse/issues/5738), [\#5746](https://github.com/matrix-org/synapse/issues/5746), [\#5752](https://github.com/matrix-org/synapse/issues/5752), [\#5770](https://github.com/matrix-org/synapse/issues/5770), [\#5774](https://github.com/matrix-org/synapse/issues/5774), [\#5792](https://github.com/matrix-org/synapse/issues/5792), [\#5793](https://github.com/matrix-org/synapse/issues/5793))

 - Improve database query performance when recording retry intervals for remote hosts. ([\#5720](https://github.com/matrix-org/synapse/issues/5720))
 - Add a set of opentracing utils. ([\#5722](https://github.com/matrix-org/synapse/issues/5722))
 - Cache result of get_version_string to reduce overhead of `/version` federation requests. ([\#5730](https://github.com/matrix-org/synapse/issues/5730))
 - Return 'user_type' in admin API user endpoints results. ([\#5731](https://github.com/matrix-org/synapse/issues/5731))
 - Don't package the sytest test blacklist file. ([\#5733](https://github.com/matrix-org/synapse/issues/5733))
 - Replace uses of returnValue with plain return, as returnValue is not needed on Python 3. ([\#5736](https://github.com/matrix-org/synapse/issues/5736))
 - Blacklist some flakey tests in worker mode. ([\#5740](https://github.com/matrix-org/synapse/issues/5740))
 - Fix some error cases in the caching layer. ([\#5749](https://github.com/matrix-org/synapse/issues/5749))

- Fix stack overflow in server key lookup code. ([\#5724](https://github.com/matrix-org/synapse/issues/5724))
- start.sh no longer uses deprecated cli option. ([\#5725](https://github.com/matrix-org/synapse/issues/5725))
- Log when we receive an event receipt from an unexpected origin. ([\#5743](https://github.com/matrix-org/synapse/issues/5743))

- Correctly handle redactions of redactions. ([\#5788](https://github.com/matrix-org/synapse/issues/5788))
- Return 404 instead of 403 when accessing /rooms/{roomId}/event/{eventId} for an event without the appropriate permissions. ([\#5798](https://github.com/matrix-org/synapse/issues/5798))
- Fix check that tombstone is a state event in push rules. ([\#5804](https://github.com/matrix-org/synapse/issues/5804))

Deprecations and Removals
-------------------------
- Synapse now no longer accepts the `-v`/`--verbose`, `-f`/`--log-file`, or `--log-config` command line flags, and removes the deprecated `verbose` and `log_file` configuration file options. Users of these options should migrate their options into the dedicated log configuration. ([\#5678](https://github.com/matrix-org/synapse/issues/5678), [\#5729](https://github.com/matrix-org/synapse/issues/5729))

@ -92,25 +97,84 @@ takes a while and is very resource intensive.
This goes against the advice in the Google style guide, but it means that
errors in the name are caught early (at import time).
- Multiple imports from the same package can be combined onto one line::
from synapse.types import GroupID, RoomID, UserID
An effort should be made to keep the individual imports in alphabetical
order.
If the list becomes long, wrap it with parentheses and split it over
multiple lines.
- As per `PEP-8 <https://www.python.org/dev/peps/pep-0008/#imports>`_,
imports should be grouped in the following order, with a blank line between
each group:
1. standard library imports
2. related third party imports
3. local application/library specific imports
- Imports within each group should be sorted alphabetically by module name.
- 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``. Making sure
that the output from this script matches the desired format is left as an
exercise for the reader!
