* Refactor oEmbed previews (#10814)Patrick Cloke2021-09-212-199/+272
| | | | | | | | | | | | | The major change is moving the decision of whether to use oEmbed further up the call-stack. This reverts the _download_url method to being a "dumb" functionwhich takes a single URL and downloads it (as it was before #7920). This also makes more minor refactorings: * Renames internal variables for clarity. * Factors out shared code between the HTML and rich oEmbed previews. * Fixes tests to preview an oEmbed image.
* Add missing type hints to non-client REST servlets. (#10817)Patrick Cloke2021-09-157-25/+56
| | | | Including admin, consent, key, synapse, and media. All REST servlets (the synapse.rest module) now require typed method definitions.
* Convert media repo's FileInfo to attrs. (#10785)Patrick Cloke2021-09-144-108/+139
| | | | This is mostly an internal change, but improves type hints in the media code.
* Request JSON for oEmbed requests (and ignore XML only providers). (#10759)Patrick Cloke2021-09-081-3/+23
| | | | | | | | This adds the format to the request arguments / URL to ensure that JSON data is returned (which is all that Synapse supports). This also adds additional error checking / filtering to the configuration file to ignore XML-only providers.
* Use attrs internally for the URL preview code & add documentation. (#10753)Patrick Cloke2021-09-071-42/+79
|
* Allow configuration of the oEmbed URLs. (#10714)Patrick Cloke2021-08-312-142/+140
| | | | | This adds configuration options (under an `oembed` section) to configure which URLs are matched to use oEmbed for URL previews.

* Mitigate media repo XSSs on IE11. (#10468)Denis Kasak2021-07-271-0/+2
| | | | | | | | IE11 doesn't support Content-Security-Policy but it has support for a non-standard X-Content-Security-Policy header, which only supports the sandbox directive. This prevents script execution, so it at least offers some protection against media repo-based attacks. Signed-off-by: Denis Kasak <dkasak@termina.org.uk>

* Remove various bits of compatibility code for Python <3.6 (#9879)Andrew Morgan2021-04-271-1/+1
| | | I went through and removed a bunch of cruft that was lying around for compatibility with old Python versions. This PR also will now prevent Synapse from starting unless you're running Python 3.6+.
* Improved validation for received requests (#9817)Richard van der Hoff2021-04-231-2/+0
| | | | | | * Simplify `start_listening` callpath * Correctly check the size of uploaded files
* remove `HomeServer.get_config` (#9815)Richard van der Hoff2021-04-141-1/+1
| | | | Every single time I want to access the config object, I have to remember whether or not we use `get_config`. Let's just get rid of it.

* Make it possible to use dmypy (#9692)Erik Johnston2021-03-261-0/+2
| | | | | | | | | Running `dmypy run` will do a `mypy` check while spinning up a daemon that makes rerunning `dmypy run` a lot faster. `dmypy` doesn't support `follow_imports = silent` and has `local_partial_types` enabled, so this PR enables those options and fixes the issues that were newly raised. Note that `local_partial_types` will be enabled by default in upcoming mypy releases.

* Handle image transparency better when thumbnailing. (#9473)Patrick Cloke2021-03-091-3/+8
| | | | Properly uses RGBA mode for 1- and 8-bit images with transparency (instead of RBG mode).
* Use the proper Request in type hints. (#9515)Patrick Cloke2021-03-017-17/+22
| | | | This also pins the Twisted version in the mypy job for CI until proper type hints are fixed throughout Synapse.
* Add support for no_proxy and case insensitive env variables (#9372)Tim Leung2021-02-261-2/+1
| | | | | | | | | | | | | | | ### Changes proposed in this PR - Add support for the `no_proxy` and `NO_PROXY` environment variables - Internally rely on urllib's [`proxy_bypass_environment`](https://github.com/python/cpython/blob/bdb941be423bde8b02a5695ccf51c303d6204bed/Lib/urllib/request.py#L2519) - Extract env variables using urllib's `getproxies`/[`getproxies_environment`](https://github.com/python/cpython/blob/bdb941be423bde8b02a5695ccf51c303d6204bed/Lib/urllib/request.py#L2488) which supports lowercase + uppercase, preferring lowercase, except for `HTTP_PROXY` in a CGI environment This does contain behaviour changes for consumers so making sure these are called out: - `no_proxy`/`NO_PROXY` is now respected - lowercase `https_proxy` is now allowed and taken over `HTTPS_PROXY` Related to #9306 which also uses `ProxyAgent` Signed-off-by: Timothy Leung tim95@hotmail.co.uk

|
* Try to recover from unknown encodings when previewing media. (#9164)Patrick Cloke2021-01-261-10/+34
| | | | | | Treat unknown encodings (according to lxml) as UTF-8 when generating a preview for HTML documents. This isn't fully accurate, but will hopefully give a reasonable title and summary.
* Return a 404 if no valid thumbnail is found. (#9163)Patrick Cloke2021-01-212-81/+158
| | | | | | If no thumbnail of the requested type exists, return a 404 instead of erroring. This doesn't quite match the spec (which does not define what happens if no thumbnail can be found), but is consistent with what Synapse already does.

It now applies to: * Federation * Identity servers * Push notifications * Checking key validitity for third-party invite events The old `federation_ip_range_blacklist` setting is still honored if present, but with reduced scope (it only applies to federation and identity servers).

* Don't bother responding to client requests that have already disconnected ↵Andrew Morgan2020-10-061-0/+6
| | | | | | | | | | (#8465) This PR ports the quick fix from https://github.com/matrix-org/synapse/pull/2796 to further methods which handle media, URL preview and `/key/v2/server` requests. This prevents a harmless `ERROR` that comes up in the logs when we were unable to respond to a client request when the client had already disconnected. In this case we simply bail out if the client has already done so. This is the 'simple fix' as suggested by https://github.com/matrix-org/synapse/issues/5304#issuecomment-574740003. Fixes https://github.com/matrix-org/synapse/issues/6700 Fixes https://github.com/matrix-org/synapse/issues/5304
* Fix bug in remote thumbnail search (#8438)Richard van der Hoff2020-10-021-20/+23
| | | | | #7124 changed the behaviour of remote thumbnails so that the thumbnailing method was included in the filename of the thumbnail. To support existing files, it included a fallback so that we would check the old filename if the new filename didn't exist. Unfortunately, it didn't apply this logic to storage providers, so any thumbnails stored on such a storage provider was broken.

| | | | If a file cannot be thumbnailed for some reason (e.g. the file is empty), then catch the exception and convert it to a reasonable error message for the client.
* Include method in thumbnail media name (#7124)DeepBlueV7.X2020-09-082-1/+46
| | | | | | | | | | | | | | This fixes an issue where different methods (crop/scale) overwrite each other. This first tries the new path. If that fails and we are looking for a remote thumbnail, it tries the old path. If that still isn't found, it continues as normal. This should probably be removed in the future, after some of the newer thumbnails were generated with the new path on most deployments. Then the overhead should be minimal if the other thumbnails need to be regenerated. Signed-off-by: Nicolas Werner <nicolas.werner@hotmail.de>

| | | | | | | | | | | | | | | | ExpiringCache required that `start()` be called before it would actually start expiring entries. A number of places didn't do that. This PR removes `start` from ExpiringCache, and automatically starts backround reaping process on creation instead.
* | added "media-src: 'self'" to CSP for resources (#3578)Jérémy Farnaud2018-09-251-0/+1
|/ | | | | | | | | | | | | | | Synapse doesn’t allow for media resources to be played directly from Chrome. It is a problem for users on other networks (e.g. IRC) communicating with Matrix users through a gateway. The gateway sends them the raw URL for the resource when a Matrix user uploads a video and the video cannot be played directly in Chrome using that URL. Chrome argues it is not authorized to play the video because of the Content Security Policy. Chrome checks for the "media-src" policy which is missing, and defauts to the "default-src" policy which is "none". As Synapse already sends "object-src: 'self'" I thought it wouldn’t be a problem to add "media-src: 'self'" to the CSP to fix this problem.

| | | | | | | | | | | | (instead of everywhere that writes a response. Or rather, the subset of places which write responses where we haven't forgotten it). This also means that we don't have to have the mysterious version_string attribute in anything with a request handler. Unfortunately it does mean that we have to pass the version string wherever we instantiate a SynapseSite, which has been c&ped 150 times, but that is code that ought to be cleaned up anyway really.

* / Improve exception handling for background processesRichard van der Hoff2018-04-271-2/+7
|/ | | | | | | | | | | | | | | | | | There were a bunch of places where we fire off a process to happen in the background, but don't have any exception handling on it - instead relying on the unhandled error being logged when the relevent deferred gets garbage-collected. This is unsatisfactory for a number of reasons: - logging on garbage collection is best-effort and may happen some time after the error, if at all - it can be hard to figure out where the error actually happened. - it is logged as a scary CRITICAL error which (a) I always forget to grep for and (b) it's not really CRITICAL if a background process we don't care about fails. So this is an attempt to add exception handling to everything we fire off into the background.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old style raise is invalid syntax in python3.
