Fixes https://github.com/element-hq/synapse/issues/19352 (See issue for history of this feature and previous PRs) > First, a [naive implementation](https://github.com/element-hq/synapse/pull/19268) of the endpoint was introduced, but it quickly ran into [performance issues on query](https://github.com/element-hq/synapse/pull/19312) and [long startup times](https://github.com/element-hq/synapse/issues/19349), leading to its [removal](https://github.com/element-hq/synapse/pull/19351). It also didn't actually work, and would fail to expose media when it was "unquarantined", so a [partial fix](https://github.com/element-hq/synapse/pull/19308) was attempted, where the suggested direction is to use a [stream](https://element-hq.github.io/synapse/latest/development/synapse_architecture/streams.html#cheatsheet-for-creating-a-new-stream) instead of a timestamp column. This PR re-introduces the API building on the previous feedback: * Adds a stream which tracks when media becomes (un)quarantined. * Runs a background update to capture already-quarantined media. * Adds a new admin API to return rows from the stream table. We track both quarantine and unquarantine actions in the stream to allow downstream consumers to process the records appropriately. Namely, to allow our Synapse exchange in HMA to remove hashes for unquarantined media (use case further explained in the [issue](https://github.com/element-hq/synapse/issues/19352)). **Note**: This knowingly does not capture all cases of media being quarantined. Other call sites are lower priority for T&S, and can be addressed in a future PR. ~~An issue will be created after this PR is merged to track those sites.~~ https://github.com/element-hq/synapse/issues/19672 ### Pull Request Checklist <!-- Please read https://element-hq.github.io/synapse/latest/development/contributing_guide.html before submitting your pull request --> * [x] Pull request is based on the develop branch * [x] Pull request includes a [changelog file](https://element-hq.github.io/synapse/latest/development/contributing_guide.html#changelog). The entry should: - Be a short description of your change which makes sense to users. "Fixed a bug that prevented receiving messages from other servers." instead of "Moved X method from `EventStore` to `EventWorkerStore`.". - Use markdown where necessary, mostly for `code blocks`. - End with either a period (.) or an exclamation mark (!). - Start with a capital letter. - Feel free to credit yourself, by adding a sentence "Contributed by @github_username." or "Contributed by [Your Name]." to the end of the entry. * [x] [Code style](https://element-hq.github.io/synapse/latest/code_style.html) is correct (run the [linters](https://element-hq.github.io/synapse/latest/development/contributing_guide.html#run-the-linters)) --------- Co-authored-by: turt2live <1190097+turt2live@users.noreply.github.com> Co-authored-by: Eric Eastwood <madlittlemods@gmail.com> Co-authored-by: Eric Eastwood <erice@element.io>
Synapse Documentation
The documentation is currently hosted here. Please update any links to point to the new website instead.
About
This directory currently holds a series of markdown files documenting how to install, use and develop Synapse. The documentation is readable directly from this repository, but it is recommended to instead browse through the website for easier discoverability.
Adding to the documentation
Most of the documentation currently exists as top-level files, as when organising them into
a structured website, these files were kept in place so that existing links would not break.
The rest of the documentation is stored in folders, such as setup, usage, and development
etc. All new documentation files should be placed in structured folders. For example:
To create a new user-facing documentation page about a new Single Sign-On protocol named "MyCoolProtocol", one should create a new file with a relevant name, such as "my_cool_protocol.md". This file might fit into the documentation structure at:
- Usage
- Configuration
- User Authentication
- Single Sign-On
- My Cool Protocol
- Single Sign-On
- User Authentication
- Configuration
Given that, one would place the new file under
usage/configuration/user_authentication/single_sign_on/my_cool_protocol.md.
Note that the structure of the documentation (and thus the left sidebar on the website) is determined by the list in SUMMARY.md. The final thing to do when adding a new page is to add a new line linking to the new documentation file:
- [My Cool Protocol](usage/configuration/user_authentication/single_sign_on/my_cool_protocol.md)
Building the documentation
The documentation is built with mdbook, and the outline of the documentation is determined by the structure of SUMMARY.md.
First, get mdbook. Then, from the root of the repository, build the documentation with:
mdbook build
The rendered contents will be outputted to a new book/ directory at the root of the repository. Please note that
index.html is not built by default, it is created by copying over the file welcome_and_overview.html to index.html
during deployment. Thus, when running mdbook serve locally the book will initially show a 404 in place of the index
due to the above. Do not be alarmed!
You can also have mdbook host the docs on a local webserver with hot-reload functionality via:
mdbook serve
The URL at which the docs can be viewed at will be logged.
Synapse configuration documentation
The Configuration Manual page is generated from a YAML file, schema/synapse-config.schema.yaml. To add new options or modify existing ones, first edit that file, then run scripts-dev/gen_config_documentation.py to generate an updated Configuration Manual markdown file.
Build the book as described above to preview it in a web browser.
Configuration and theming
The look and behaviour of the website is configured by the book.toml file at the root of the repository. See mdbook's documentation on configuration for available options.
The site can be themed and additionally extended with extra UI and features. See website_files/README.md for details.
