Synapse 1.39.0rc2 (2021-07-22)
Synapse 1.46.0 (2021-11-02)
===========================
The cause of the [performance regression affecting Synapse 1.44](https://github.com/matrix-org/synapse/issues/11049) has been identified and fixed. ([\#11177](https://github.com/matrix-org/synapse/issues/11177))
Bugfixes
--------
- Fix a bug introduced in v1.46.0rc1 where URL previews of some XML documents would fail. ([\#11196](https://github.com/matrix-org/synapse/issues/11196))
Synapse 1.46.0rc1 (2021-10-27)
==============================
Features
--------
- Add support for Ubuntu 21.10 "Impish Indri". ([\#11024](https://github.com/matrix-org/synapse/issues/11024))
- Port the Password Auth Providers module interface to the new generic interface. ([\#10548](https://github.com/matrix-org/synapse/issues/10548), [\#11180](https://github.com/matrix-org/synapse/issues/11180))
- Experimental support for the thread relation defined in [MSC3440](https://github.com/matrix-org/matrix-doc/pull/3440). ([\#11088](https://github.com/matrix-org/synapse/issues/11088), [\#11181](https://github.com/matrix-org/synapse/issues/11181), [\#11192](https://github.com/matrix-org/synapse/issues/11192))
- Users admin API can now also modify user type in addition to allowing it to be set on user creation. ([\#11174](https://github.com/matrix-org/synapse/issues/11174))
Bugfixes
--------

- **[GHSA-3x4c-pq33-4w3q](https://github.com/matrix-org/synapse/security/advisories/GHSA-3x4c-pq33-4w3q) / [CVE-2021-39164](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-39164): Enumerating a private room's list of members and their display names.**
If an unauthorized user both knows the Room ID of a private room *and* that room's history visibility is set to `shared`, then they may be able to enumerate the room's members, including their display names.
The unauthorized user must be on the same homeserver as a user who is a member of the target room.
Fixed by [52c7a51cf](https://github.com/matrix-org/synapse/commit/52c7a51cf).
- **[GHSA-jj53-8fmw-f2w2](https://github.com/matrix-org/synapse/security/advisories/GHSA-jj53-8fmw-f2w2) / [CVE-2021-39163](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-39163): Disclosing a private room's name, avatar, topic, and number of members.**
If an unauthorized user knows the Room ID of a private room, then its name, avatar, topic, and number of members may be disclosed through Group / Community features.
The unauthorized user must be on the same homeserver as a user who is a member of the target room, and their homeserver must allow non-administrators to create groups (`enable_group_creation` in the Synapse configuration; off by default).
Fixed by [cb35df940a](https://github.com/matrix-org/synapse/commit/cb35df940a), [\#10723](https://github.com/matrix-org/synapse/issues/10723).

# 1. Who can contribute to Synapse?
Everyone is welcome to contribute code to [matrix.org
projects](https://github.com/matrix-org), provided that they are willing to
license their contributions under the same license as the project itself. We
follow a simple 'inbound=outbound' model for contributions: the act of
submitting an 'inbound' contribution means that the contributor agrees to
license the code under the same terms as the project's overall 'outbound'
license - in our case, this is almost always Apache Software License v2 (see
[LICENSE](LICENSE)).
# 2. What do I need?
The code of Synapse is written in Python 3. To do pretty much anything, you'll need [a recent version of Python 3](https://wiki.python.org/moin/BeginnersGuide/Download).
The source code of Synapse is hosted on GitHub. You will also need [a recent version of git](https://github.com/git-guides/install-git).
For some tests, you will need [a recent version of Docker](https://docs.docker.com/get-docker/).
# 3. Get the source.
The preferred and easiest way to contribute changes is to fork the relevant
project on GitHub, and then [create a pull request](
https://help.github.com/articles/using-pull-requests/) to ask us to pull your
changes into our repo.
Please base your changes on the `develop` branch.

git clone git@github.com:YOUR_GITHUB_USER_NAME/synapse.git
git checkout develop
```
If you need help getting started with git, this is beyond the scope of the document, but you
can find many good git tutorials on the web.
# 4. Install the dependencies
## Under Unix (macOS, Linux, BSD, ...)
Once you have installed Python 3 and added the source, please open a terminal and
setup a *virtualenv*, as follows:
```sh
cd path/where/you/have/cloned/the/repository
python3 -m venv ./env
source ./env/bin/activate
pip install -e ".[all,lint,mypy,test]"
pip install tox
```
This will install the developer dependencies for the project.
## Under Windows
TBD
# 5. Get in touch.
Join our developer community on Matrix: #synapse-dev:matrix.org !
# 6. Pick an issue.
Fix your favorite problem or perhaps find a [Good First Issue](https://github.com/matrix-org/synapse/issues?q=is%3Aopen+is%3Aissue+label%3A%22Good+First+Issue%22)
to work on.
# 7. Turn coffee and documentation into code and documentation!
Synapse's code style is documented [here](docs/code_style.md). Please follow
it, including the conventions for the [sample configuration
file](docs/code_style.md#configuration-file-format).
There is a growing amount of documentation located in the [docs](docs)
directory. This documentation is intended primarily for sysadmins running their
own Synapse instance, as well as developers interacting externally with
Synapse. [docs/dev](docs/dev) exists primarily to house documentation for
Synapse developers. [docs/admin_api](docs/admin_api) houses documentation
regarding Synapse's Admin API, which is used mostly by sysadmins and external
service developers.
If you add new files added to either of these folders, please use [GitHub-Flavoured
Markdown](https://guides.github.com/features/mastering-markdown/).
Some documentation also exists in [Synapse's GitHub
Wiki](https://github.com/matrix-org/synapse/wiki), although this is primarily
contributed to by community authors.
# 8. Test, test, test!
<a name="test-test-test"></a>
While you're developing and before submitting a patch, you'll
want to test your code.
## Run the linters.
The linters look at your code and do two things:
- ensure that your code follows the coding style adopted by the project;
- catch a number of errors in your code.
They're pretty fast, don't hesitate!
```sh
source ./env/bin/activate
./scripts-dev/lint.sh
```
Note that this script *will modify your files* to fix styling errors.
Make sure that you have saved all your files.
If you wish to restrict the linters to only the files changed since the last commit
(much faster!), you can instead run:
```sh
source ./env/bin/activate
./scripts-dev/lint.sh -d
```
Or if you know exactly which files you wish to lint, you can instead run:
```sh
source ./env/bin/activate
./scripts-dev/lint.sh path/to/file1.py path/to/file2.py path/to/folder
```
## Run the unit tests.
The unit tests run parts of Synapse, including your changes, to see if anything
was broken. They are slower than the linters but will typically catch more errors.
```sh
source ./env/bin/activate
trial tests
```
If you wish to only run *some* unit tests, you may specify
another module instead of `tests` - or a test class or a method:
```sh
source ./env/bin/activate
trial tests.rest.admin.test_room tests.handlers.test_admin.ExfiltrateData.test_invite
```
If your tests fail, you may wish to look at the logs (the default log level is `ERROR`):
```sh
less _trial_temp/test.log
```
To increase the log level for the tests, set `SYNAPSE_TEST_LOG_LEVEL`:
```sh
SYNAPSE_TEST_LOG_LEVEL=DEBUG trial tests
```
## Run the integration tests.
The integration tests are a more comprehensive suite of tests. They
run a full version of Synapse, including your changes, to check if
anything was broken. They are slower than the unit tests but will
typically catch more errors.
The following command will let you run the integration test with the most common
configuration:
```sh
$ docker run --rm -it -v /path/where/you/have/cloned/the/repository\:/src:ro -v /path/to/where/you/want/logs\:/logs matrixdotorg/sytest-synapse:py37
```
This configuration should generally cover your needs. For more details about other configurations, see [documentation in the SyTest repo](https://github.com/matrix-org/sytest/blob/develop/docker/README.md).
# 9. Submit your patch.
Once you're happy with your patch, it's time to prepare a Pull Request.
To prepare a Pull Request, please:
1. verify that [all the tests pass](#test-test-test), including the coding style;
2. [sign off](#sign-off) your contribution;
3. `git push` your commit to your fork of Synapse;
4. on GitHub, [create the Pull Request](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request);
5. add a [changelog entry](#changelog) and push it to your Pull Request;
6. for most contributors, that's all - however, if you are a member of the organization `matrix-org`, on GitHub, please request a review from `matrix.org / Synapse Core`.
## Changelog
All changes, even minor ones, need a corresponding changelog / newsfragment
entry. These are managed by [Towncrier](https://github.com/hawkowl/towncrier).
To create a changelog entry, make a new file in the `changelog.d` directory named
in the format of `PRnumber.type`. The type can be one of the following:
* `feature`
* `bugfix`
* `docker` (for updates to the Docker image)
* `doc` (for updates to the documentation)
* `removal` (also used for deprecations)
* `misc` (for internal-only changes)
This file will become part of our [changelog](
https://github.com/matrix-org/synapse/blob/master/CHANGES.md) at the next
release, so the content of the file should be a short description of your
change in the same style as the rest of the changelog. The file can contain Markdown
formatting, and should end with a full stop (.) or an exclamation mark (!) for
consistency.
Adding credits to the changelog is encouraged, we value your
contributions and would like to have you shouted out in the release notes!
For example, a fix in PR #1234 would have its changelog entry in
`changelog.d/1234.bugfix`, and contain content like:
> The security levels of Florbs are now validated when received
> via the `/federation/florb` endpoint. Contributed by Jane Matrix.
If there are multiple pull requests involved in a single bugfix/feature/etc,
then the content for each `changelog.d` file should be the same. Towncrier will
merge the matching files together into a single changelog entry when we come to
release.
### How do I know what to call the changelog file before I create the PR?
Obviously, you don't know if you should call your newsfile
`1234.bugfix` or `5678.bugfix` until you create the PR, which leads to a
chicken-and-egg problem.
There are two options for solving this:
1. Open the PR without a changelog file, see what number you got, and *then*
add the changelog file to your branch (see [Updating your pull
request](#updating-your-pull-request)), or:
1. Look at the [list of all
issues/PRs](https://github.com/matrix-org/synapse/issues?q=), add one to the
highest number you see, and quickly open the PR before somebody else claims
your number.
[This
script](https://github.com/richvdh/scripts/blob/master/next_github_number.sh)
might be helpful if you find yourself doing this a lot.
Sorry, we know it's a bit fiddly, but it's *really* helpful for us when we come
to put together a release!
### Debian changelog
Changes which affect the debian packaging files (in `debian`) are an
exception to the rule that all changes require a `changelog.d` file.
In this case, you will need to add an entry to the debian changelog for the
next release. For this, run the following command:
```
dch
```
This will make up a new version number (if there isn't already an unreleased
version in flight), and open an editor where you can add a new changelog entry.
(Our release process will ensure that the version number and maintainer name is
corrected for the release.)
If your change affects both the debian packaging *and* files outside the debian
directory, you will need both a regular newsfragment *and* an entry in the
debian changelog. (Though typically such changes should be submitted as two
separate pull requests.)
## Sign off
In order to have a concrete record that your contribution is intentional
and you agree to license it under the same terms as the project's license, we've adopted the
same lightweight approach that the Linux Kernel
[submitting patches process](
https://www.kernel.org/doc/html/latest/process/submitting-patches.html#sign-your-work-the-developer-s-certificate-of-origin>),
[Docker](https://github.com/docker/docker/blob/master/CONTRIBUTING.md), and many other
projects use: the DCO (Developer Certificate of Origin:
http://developercertificate.org/). This is a simple declaration that you wrote
the contribution or otherwise have the right to contribute it to Matrix:
```
Developer Certificate of Origin
Version 1.1
Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
660 York Street, Suite 102,
San Francisco, CA 94110 USA
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
Developer's Certificate of Origin 1.1
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I
have the right to submit it under the open source license
indicated in the file; or
(b) The contribution is based upon previous work that, to the best
of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that
work with modifications, whether created in whole or in part
by me, under the same open source license (unless I am
permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified
it.
(d) I understand and agree that this project and the contribution
are public and that a record of the contribution (including all
personal information I submit with it, including my sign-off) is
maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
```
If you agree to this for your contribution, then all that's needed is to
include the line in your commit or pull request comment:
```
Signed-off-by: Your Name <your@email.example.org>
```
We accept contributions under a legally identifiable name, such as
your name on government documentation or common-law names (names
claimed by legitimate usage or repute). Unfortunately, we cannot
accept anonymous contributions at this time.
Git allows you to add this signoff automatically when using the `-s`
flag to `git commit`, which uses the name and email set in your
`user.name` and `user.email` git configs.
# 10. Turn feedback into better code.
Once the Pull Request is opened, you will see a few things:
1. our automated CI (Continuous Integration) pipeline will run (again) the linters, the unit tests, the integration tests and more;
2. one or more of the developers will take a look at your Pull Request and offer feedback.
From this point, you should:
1. Look at the results of the CI pipeline.
- If there is any error, fix the error.
2. If a developer has requested changes, make these changes and let us know if it is ready for a developer to review again.
3. Create a new commit with the changes.
- Please do NOT overwrite the history. New commits make the reviewer's life easier.
- Push this commits to your Pull Request.
4. Back to 1.
Once both the CI and the developers are happy, the patch will be merged into Synapse and released shortly!
# 11. Find a new issue.
By now, you know the drill!
# Notes for maintainers on merging PRs etc
There are some notes for those with commit access to the project on how we
manage git [here](docs/development/git.md).
# Conclusion
That's it! Matrix is a very open and collaborative project as you might expect
given our obsession with open communication. If we're going to successfully
matrix together all the fragmented communication technologies out there we are
reliant on contributions and collaboration from the community to do so. So
please get involved - and we hope you have as much fun hacking on Matrix as we
do!
Please see the [contributors' guide](https://matrix-org.github.io/synapse/latest/development/contributing_guide.html) in our rendered documentation.
