2017-10-09Fed server: use a linearizer for ongoing transactionsRichard van der Hoff1-1/+29
We don't want to process the same transaction multiple times concurrently, so use a linearizer.
2017-10-09fed server: refactor on_incoming_transactionRichard van der Hoff1-24/+29
Move as much as possible to after the have_responded check, and reduce the number of times we iterate over the pdu list.
2017-10-09Fed server: Move origin-check code to _handle_received_pduRichard van der Hoff1-24/+24
The response-building code expects there to be an entry in the `results` list for each entry in the pdu_list, so the early `continue` was messing this up. That doesn't really matter, because all that the federation client does is log any errors, but it's pretty poor form.

2017-10-06Fix up logcontext handling in (federation) TransactionQueueRichard van der Hoff1-16/+32
Avoid using preserve_context_over_function, which has problems with respect to logcontexts.
2017-10-06Fix logcontext handling for concurrently_executeRichard van der Hoff1-2/+2
Avoid preserve_context_over_deferred, which is broken.
2017-10-06Fix up deferred handling in federation.pyRichard van der Hoff1-24/+21
* Avoid preserve_context_over_deferred, which is broken * set consumeErrors=True on defer.gatherResults, to avoid spurious "unhandled failure" erros

2017-10-05Fix notif kws that start/end with non-word charsDavid Baker1-2/+21
Only prepend / append word bounary characters if the search expression starts or ends with a word character, otherwise they don't work because there's no word bounary between whitespace and a non-word char.

2017-10-03Ignore incoming events for rooms that we have leftErik Johnston2-0/+55
When synapse receives an event for a room its not in over federation, it double checks with the remote server to see if it is in fact in the room. This is done so that if the server has forgotten about the room (usually as a result of the database being dropped) it can recover from it. However, in the presence of state resets in large rooms, this can cause a lot of work for servers that have legitimately left. As a hacky solution that supports both cases we drop incoming events for rooms that we have explicitly left. This means that we no longer support the case of servers having forgotten that they've rejoined a room, but that is sufficiently rare that we're not going to support it for now.

https://github.com/matrix-org/synapse/issues/2187 contains a report of a port failing due to nul characters somewhere in the search table. Let's try dropping the offending rows.
2017-09-30Unfreeze event before serializing with ujsonJeremy Cline1-1/+2
In newer versions of https://github.com/esnme/ultrajson, ujson does not serialize frozendicts (introduced in esnme/ultrajson@53f85b1). Although the PyPI version is still 1.35, Fedora ships with a build from commit esnme/ultrajson@2f1d487. This causes the serialization to fail if the distribution-provided package is used. This runs the event through the unfreeze utility before serializing it. Thanks to @ignatenkobrain for tracking down the root cause. fixes #2351 Signed-off-by: Jeremy Cline <jeremy@jcline.org>
