I wonder if this correctly sets the isolation level that we set on the connection? I suppose it doesn't really matter too much
There was a problem hiding this comment.
well, the isolation level is set when we open the connection. I don't think there's a need to do it again here?

Synapse 1.21.2 (2020-10-15) =========================== Debian packages and Docker images have been rebuilt using the latest versions of dependency libraries, including authlib 0.15.1. Please see bugfixes below. Security advisory ----------------- * HTML pages served via Synapse were vulnerable to cross-site scripting (XSS) attacks. All server administrators are encouraged to upgrade. ([\#8444](matrix-org/synapse#8444)) ([CVE-2020-26891](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-26891)) This fix was originally included in v1.21.0 but was missing a security advisory. This was reported by [Denis Kasak](https://github.com/dkasak). Bugfixes -------- - Fix rare bug where sending an event would fail due to a racey assertion. ([\#8530](matrix-org/synapse#8530)) - An updated version of the authlib dependency is included in the Docker and Debian images to fix an issue using OpenID Connect. See [\#8534](matrix-org/synapse#8534) for details. Synapse 1.21.1 (2020-10-13) =========================== This release fixes a regression in v1.21.0 that prevented debian packages from being built. It is otherwise identical to v1.21.0. Synapse 1.21.0 (2020-10-12) =========================== No significant changes since v1.21.0rc3. As [noted in v1.20.0](https://github.com/matrix-org/synapse/blob/release-v1.21.0/CHANGES.md#synapse-1200-2020-09-22), a future release will drop support for accessing Synapse's [Admin API](https://github.com/matrix-org/synapse/tree/master/docs/admin_api) under the `/_matrix/client/*` endpoint prefixes. At that point, the Admin API will only be accessible under `/_synapse/admin`. Synapse 1.21.0rc3 (2020-10-08) ============================== Bugfixes -------- - Fix duplication of events on high traffic servers, caused by PostgreSQL `could not serialize access due to concurrent update` errors. ([\#8456](matrix-org/synapse#8456)) Internal Changes ---------------- - Add Groovy Gorilla to the list of distributions we build `.deb`s for. ([\#8475](matrix-org/synapse#8475)) Synapse 1.21.0rc2 (2020-10-02) ============================== Features -------- - Convert additional templates from inline HTML to Jinja2 templates. ([\#8444](matrix-org/synapse#8444)) Bugfixes -------- - Fix a regression in v1.21.0rc1 which broke thumbnails of remote media. ([\#8438](matrix-org/synapse#8438)) - Do not expose the experimental `uk.half-shot.msc2778.login.application_service` flow in the login API, which caused a compatibility problem with Element iOS. ([\#8440](matrix-org/synapse#8440)) - Fix malformed log line in new federation "catch up" logic. ([\#8442](matrix-org/synapse#8442)) - Fix DB query on startup for negative streams which caused long start up times. Introduced in [\#8374](matrix-org/synapse#8374). ([\#8447](matrix-org/synapse#8447)) Synapse 1.21.0rc1 (2020-10-01) ============================== Features -------- - Require the user to confirm that their password should be reset after clicking the email confirmation link. ([\#8004](matrix-org/synapse#8004)) - Add an admin API `GET /_synapse/admin/v1/event_reports` to read entries of table `event_reports`. Contributed by @dklimpel.
