From 36dc15412de9fc1bb2ba955c8b6f2da20d2ca20f Mon Sep 17 00:00:00 2001 From: Brendan Abolivier Date: Fri, 16 Jul 2021 18:11:53 +0200 Subject: Add a module type for account validity (#9884) This adds an API for third-party plugin modules to implement account validity, so they can provide this feature instead of Synapse. The module implementing the current behaviour for this feature can be found at https://github.com/matrix-org/synapse-email-account-validity. To allow for a smooth transition between the current feature and the new module, hooks have been added to the existing account validity endpoints to allow their behaviours to be overridden by a module. --- changelog.d/9884.feature | 1 + docs/modules.md | 47 ++++- docs/sample_config.yaml | 85 --------- synapse/api/auth.py | 17 +- synapse/config/account_validity.py | 102 ++--------- synapse/handlers/account_validity.py | 128 ++++++++++++- synapse/handlers/register.py | 5 + synapse/module_api/__init__.py | 219 +++++++++++++++++++++-- synapse/module_api/errors.py | 6 +- synapse/push/pusherpool.py | 24 +-- synapse/rest/admin/users.py | 24 ++- synapse/rest/client/v2_alpha/account_validity.py | 7 +- tests/test_state.py | 1 + 13 files changed, 438 insertions(+), 228 deletions(-) create mode 100644 changelog.d/9884.feature diff --git a/changelog.d/9884.feature b/changelog.d/9884.feature new file mode 100644 index 0000000000..525fd2f93c --- /dev/null +++ b/changelog.d/9884.feature @@ -0,0 +1 @@ +Add a module type for the account validity feature. diff --git a/docs/modules.md b/docs/modules.md index bec1c06d15..c4cb7018f7 100644 --- a/docs/modules.md +++ b/docs/modules.md @@ -63,7 +63,7 @@ Modules can register web resources onto Synapse's web server using the following API method: ```python -def ModuleApi.register_web_resource(path: str, resource: IResource) +def ModuleApi.register_web_resource(path: str, resource: IResource) -> None ``` The path is the full absolute path to register the resource at.
