From 0c0b82b6d18102694f9ff1c40b94e5dd124c21d8 Mon Sep 17 00:00:00 2001 From: Andrew Morgan <1342360+anoadragon453@users.noreply.github.com> Date: Fri, 6 Sep 2019 11:35:28 +0100 Subject: [PATCH] Allow Synapse to send registration emails + choose Synapse or an external server to handle 3pid validation (#5987) This is a combination of a few different PRs, finally all being merged into `develop`: * #5875 * #5876 * #5868 (This one added the `/versions` flag but the flag itself was actually [backed out](https://github.com/matrix-org/synapse/commit/891afb57cbdf9867f2848341b29c75d6f35eef5a#diff-e591d42d30690ffb79f63bb726200891) in #5969. What's left is just giving /versions access to the config file, which could be useful in the future) * #5835 * #5969 * #5940 Clients should not actually use the new registration functionality until https://github.com/matrix-org/synapse/pull/5972 is merged. UPGRADE.rst, changelog entries and config file changes should all be reviewed closely before this PR is merged. --- UPGRADE.rst | 63 +++++ changelog.d/5835.feature | 1 + changelog.d/5868.feature | 1 + changelog.d/5875.misc | 1 + changelog.d/5876.feature | 1 + changelog.d/5940.feature | 1 + changelog.d/5969.feature | 1 + contrib/cmdclient/console.py | 2 + docs/sample_config.yaml | 56 +++- synapse/app/client_reader.py | 2 +- synapse/config/emailconfig.py | 122 ++++++-- synapse/config/registration.py | 36 +++ synapse/handlers/account_validity.py | 12 +- synapse/handlers/auth.py | 34 +-- synapse/handlers/identity.py | 178 +++++++++--- synapse/push/mailer.py | 83 ++++-- synapse/push/pusher.py | 17 +- synapse/res/templates/password_reset.html | 2 +- synapse/res/templates/password_reset.txt | 4 +- .../res/templates/password_reset_failure.html | 4 +- synapse/res/templates/registration.html | 11 + synapse/res/templates/registration.txt | 10 + .../res/templates/registration_failure.html | 6 + .../res/templates/registration_success.html | 6 + synapse/rest/__init__.py | 2 +- synapse/rest/client/v2_alpha/_base.py | 2 + synapse/rest/client/v2_alpha/account.py | 264 ++++++++---------- synapse/rest/client/v2_alpha/register.py | 196 ++++++++++++- synapse/rest/client/versions.py | 8 +- 29 files changed, 822 insertions(+), 304 deletions(-) create mode 100644 changelog.d/5835.feature create mode 100644 changelog.d/5868.feature create mode 100644 changelog.d/5875.misc create mode 100644 changelog.d/5876.feature create mode 100644 changelog.d/5940.feature create mode 100644 changelog.d/5969.feature create mode 100644 synapse/res/templates/registration.html create mode 100644 synapse/res/templates/registration.txt create mode 100644 synapse/res/templates/registration_failure.html create mode 100644 synapse/res/templates/registration_success.html diff --git a/UPGRADE.rst b/UPGRADE.rst index cf228c7c52..dddcd75fda 100644 --- a/UPGRADE.rst +++ b/UPGRADE.rst @@ -49,6 +49,56 @@ returned by the Client-Server API: # configured on port 443. curl -kv https:///_matrix/client/versions 2>&1 | grep "Server:" +Upgrading to v1.4.0 +=================== + +Config options +-------------- + +**Note: Registration by email address or phone number will not work in this release unless +some config options are changed from their defaults.** + +This is due to Synapse v1.4.0 now defaulting to sending registration and password reset tokens +itself.
