From 3e4cdfe5d9b6152b9a0b7f7ad22623c2bf19f7ff Mon Sep 17 00:00:00 2001 From: Patrick Cloke Date: Fri, 15 Jan 2021 11:18:09 -0500 Subject: [PATCH] Add an admin API endpoint to protect media. (#9086) Protecting media stops it from being quarantined when e.g. all media in a room is quarantined. This is useful for sticker packs and other media that is uploaded by server administrators, but used by many people. --- changelog.d/9086.feature | 1 + docs/admin_api/media_admin_api.md | 24 ++++++++++++ synapse/rest/admin/media.py | 64 +++++++++++++++++++++++-------- tests/rest/admin/test_admin.py | 8 ++-- 4 files changed, 79 insertions(+), 18 deletions(-) create mode 100644 changelog.d/9086.feature diff --git a/changelog.d/9086.feature b/changelog.d/9086.feature new file mode 100644 index 000000000..3e678e24d --- /dev/null +++ b/changelog.d/9086.feature @@ -0,0 +1 @@ +Add an admin API for protecting local media from quarantine. diff --git a/docs/admin_api/media_admin_api.md b/docs/admin_api/media_admin_api.md index dfb8c5d75..90faeaaef 100644 --- a/docs/admin_api/media_admin_api.md +++ b/docs/admin_api/media_admin_api.md @@ -4,6 +4,7 @@ * [Quarantining media by ID](#quarantining-media-by-id) * [Quarantining media in a room](#quarantining-media-in-a-room) * [Quarantining all media of a user](#quarantining-all-media-of-a-user) + * [Protecting media from being quarantined](#protecting-media-from-being-quarantined) - [Delete local media](#delete-local-media) * [Delete a specific local media](#delete-a-specific-local-media) * [Delete local media by date or size](#delete-local-media-by-date-or-size) @@ -123,6 +124,29 @@ The following fields are returned in the JSON response body: * `num_quarantined`: integer - The number of media items successfully quarantined +## Protecting media from being quarantined + +This API protects a single piece of local media from being quarantined using the +above APIs.
