+# Maunium Synapse
+This is a fork of [Synapse] to remove dumb limits and fix bugs that the
+upstream devs don't want to fix.
+
+The only official distribution is the docker image in the [GitLab container
+registry], but you can also install from source ([upstream instructions]).
+
+The master branch and `:latest` docker tag are upgraded to each upstream
+release candidate very soon after release (usually within 10 minutes†). There
+are also docker tags for each release, e.g. `:1.75.0`. If you don't want RCs,
+use the specific release tags.
+
+†If there are merge conflicts, the update may be delayed for up to a few days
+after the full release.

+## List of changes
+* Default power level for room creator is 9001 instead of 100.
+* Room creator can specify a custom room ID with the `room_id` param in the
+  request body. If the room ID is already in use, it will return `M_CONFLICT`.
+* ~~URL previewer user agent includes `Bot` so Twitter previews work properly.~~
+  Upstreamed after over 2 years 🎉
+* ~~Local event creation concurrency is disabled to avoid unnecessary state
+  resolution.~~ Upstreamed after over 3 years 🎉
+* Register admin API can register invalid user IDs.
+* Docker image with jemalloc enabled by default.
+* Config option to allow specific users to send events without unnecessary
+  validation.
+* Config option to allow specific users to receive events that are usually
+  filtered away (e.g. `org.matrix.dummy_event` and `m.room.aliases`).
+* Config option to allow specific users to use timestamp massaging without
+  being appservice users.
+* Removed bad pusher URL validation.
+* webp images are thumbnailed to webp instead of jpeg to avoid losing
+  transparency.
+* Media repo `Cache-Control` header says `immutable` and 1 year for all media
+  that exists, as media IDs in Matrix are immutable.
+* Allowed sending custom data with read receipts.
+
+You can view the full list of changes on the [meow-patchset] branch.
+Additionally, historical patch sets are saved as `meow-patchset-vX` [tags].

+# Schema symlinks
+
+This directory contains symlinks to the latest dump of the postgres full schema. This is useful to have, as it allows IDEs to understand our schema and provide autocomplete, linters, inspections, etc.
+
+In particular, the DataGrip functionality in IntelliJ's products seems to only consider files called `*.sql` when defining a schema from DDL; `*.sql.postgres` will be ignored. To get around this we symlink those files to ones ending in `.sql`. We've chosen to ignore the `.sql.sqlite` schema dumps here, as they're not intended for production use (and are much quicker to test against).
+
+## Example
+![](datagrip-aware-of-schema.png)
+
+## Caveats
+
+- Doesn't include temporary tables created ad-hoc by Synapse.
+- Postgres only. IDEs will likely be confused by SQLite-specific queries.
+- Will not include migrations created after the latest schema dump.
+- Symlinks might confuse checkouts on Windows systems.
+
+## Instructions
+
+### Jetbrains IDEs with DataGrip plugin
+
+- View -> Tool Windows -> Database
+- `+` Icon -> DDL Data Source
+- Pick a name, e.g. `Synapse schema dump`
+- Under sources, click `+`.
+- Add an entry with Path pointing to this directory, and dialect set to PostgreSQL.
+- OK, and OK.
+- IDE should now be aware of the schema.
+- Try control-clicking on a table name in a bit of SQL e.g. in `_get_forgotten_rooms_for_user_txn`.

+# Synapse Docker
+
+### 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:
+
+```
+docker-compose run --rm -e SYNAPSE_SERVER_NAME=my.matrix.host -e SYNAPSE_REPORT_STATS=yes synapse generate
+```
+
+(This will also generate necessary signing keys.)
+
+Then, customize your configuration and run the server:
+
+```
+docker-compose up -d
+```
+
+### More information
+
+For more information on required environment variables and mounts, see the main docker documentation at [/docker/README.md](../../docker/README.md)
