This fixes the original issue that #5598 was the root cause of; when
the user returns to a Zulip browser tab after they've been idle past
the timeout (10 min, per IDLE_EVENT_QUEUE_TIMEOUT_SECS), we now
correctly reload the page even if they're using Zulip in German or
another non-English language where we have a translation for the
relevant error message.
The one purpose this exception was serving was to carry a message
in `msg`. We can do that with `JsonableError`, and as a bonus replace
a repetition of the familiar "'result': 'error', ..." JSON pattern
with a call to a common implementation.
Also wrap the error messages for translation -- we hadn't been doing
that, oops. Our linter notices that issue now that it's the familiar
JsonableError class.
There's one other potential change in behavior here: this
except-clause might now catch a JsonableError raised from some other
code. That seems like a bonus, if so; the handler isn't doing
anything actually specific to this code, and the more exceptions it
successfully turns into proper error responses to the client and lines
in the log, the better.
I pushed a bunch of commits that attempted to introduce
the concept of `client_message_id` into our server, as
part of cleaning up our codepaths related to messages you
sent (both for the locally echoed case and for the host
case).
When we deployed this, we had some strange failures involving
double-echoed messages and issues advancing the pointer that appeared
related to #5779. We didn't get to the bottom of exactly why the PR
caused havoc, but I decided there was a cleaner approach, anyway.
We are deprecating local_id/local_message_id on the Python server.
Instead of the server knowing about the client's implementation of
local id, with the message id = 9999.01 scheme, we just send the
server an opaque id to send back to us.
This commit changes the name from local_id -> client_message_id,
but it doesn't change the actual values passed yet.
The goal for client_key in future commits will be to:
* Have it for all messages, not just locally rendered messages
* Not have it overlap with server-side message ids.
The history behind local_id having numbers like 9999.01 is that
they are actually interim message ids and the numerical value is
used for rendering the message list when we do client-side rendering.
This reverts commit 7bf10ec74f.
Apparently, SockJS 1.1.1 is broken with the browser used in our legacy
desktop app, resulting in messages being silently not sent.
