Important changes in this commit:
* We only cache message list for "Combined feed" if it is the
default view.
* We modify existing handling of home message list code so that
it can be used to for any message list that we want to cache
using a new `preserve_rendered_state` variable.
* narrow_state.filter() returns the filter of combined feed view list
instead of `undefined`.
* We start fetching messages from the latest message on app load.
* Messages in all messages data and Recent view are always synced.
* If combined feed view list is not cached, we don't track it's
last pointer, effectively sending user to the latest unread
message always .
Some files already were using `noop` in place of `() => {}`.
It's both clearer what it means and is easier to type.
This updates all test files to fully use `noop`, and
adds a shared import from the test lib file.
In commit 92ad988144, we removed the local echo code that tried
to re-render locally echoed messages that were rendered right before
a server/browser restart. These changes removed the only event
triggered by `"home_view_loaded.zulip"`.
This removes the remaining `"home_view_loaded.zulip"` event trigger
in web/src/server_events.js since it no longer triggers any events.
This removes the production reporting to `/json/report/error` upon
`blueslip.error`, and replaces it with reporting to Sentry, if
enabled. Sentry provides better reporting and grouping for exceptions
than the email- and `#errors`-reporting provided by the
`/json/report/error` endpoint.
The development behaviour of rendering `blueslip.error` messages and
stacktraces immediately, and stopping execution, is preserved.
To better chain exception information, the whole previous exception is
passed to `blueslip.error`, not just the stack, and the second
parameter is formalized to be an object to map to Sentry's "context"
concept.
This lets us simplify the long-ish ‘../../static/js’ paths, and will
remove the need for the ‘zrequire’ wrapper.
