1748681 - [meta] IPC handling of very large messages

Status: NEW

(Core :: IPC, enhancement)

Description

[Nika Layzell [:nika] (ni? for response)]

If you attempt to send a message which is larger than 256Mb over IPC, we currently crash the sending process, as the IPC message is too large. For very large messages, this currently often means sending the message separately in shared memory, or manually fragmenting it into chunks which are streamed asynchronously (e.g. using an IPCStream). This is quite inconvenient to handle right now, and there are a number of messages where neither of these options are currently very practical.

This bug is to track the various bugs in this area and the ongoing and potential projects to fix this issue, allowing us to handle these very large messages without crashing.
