We recently changed the populate_db data set to include more variable
message content, which happened to include the possibility of the word
"lunch" appearing in the test messages. This caused occasional
failures of the search tests that looked for messages containing
"lunch" starting at the beginning of time, not the beginning of the
test.
This commits adds new helper functions which are:
* get_users_for_soft_deactivation(): This function can be used to
fetch a list of human users which pass the criteria of minimum
inactivity period (in days) passed as a parameter to the function.
* do_soft_activate_users(): Given a list of users this function
reactivates them and help them catch up with the missing message
rows for them in the UserMessage table.
This function will help us in creating undisturbed experience for
returning soft deactivated users.
Tweaked by tabbott to fix minor performance and clarity issues.
With this change, we get as far as printing the message
"APNS: Sending apple push notification to devices" to the
log when a recent TestFlight build of the app is due for
a notification, and then don't hit an exception. But
on the other hand I still don't get an actual notification
on my phone, so there's still some debugging to do.
Here are the functions in top_left_corner:
get_global_filter_li: pure code move
update_count_in_dom: simplifed copy of similar function in stream_list.js
update_dom_with_unread_counts: pure code move, split out from function
of same name in stream_list.js
delselect_top_left_corner_items: pure code move
handle_narrow_activated: pure code move + rename
handle_narrow_deactivated: pure code move, split out from from function
of smae name in stream_list.js
This function was actually de-selecting stream sidebar items
before. Now we just explicitly de-select top-left items in it,
and we do stream-sidebar stuff in update_stream_sidebar_for_narrow().
This field is convenient for bankruptcy checks. Clients could
calculate it from page_params.unread_msgs before this change, but
it would kind of a painful calculation.
To add count, we had to simplify the mypy annotations, which weren't
really accurate before.
Previously, when you switched to a stream narrow with the central
message outside the range of messages cached in the browser, we would
reset the UI for loading more messages, but not actually reset the
state for whether it should be possible.
This seems to have been an oversight in refactoring back in 2014.
Fixes#6109.
With this flag turned on, all streams will have a "more topics"
link, and clicking that link will always fetch topics from the
server to show a complete list of topics that you have had messages
for on that stream.
Note that if you only recently joined a public stream, your list
of topics won't go back to before you joined the stream, even though
that content is searchable. We may change that in the future, but
we will need to be careful about spamming folks who frequently
unsubscribe from streams.
Until we have an easy way to consistently determine whether a
stream has more topics than have been loaded already, we err
on the side of showing a "more topics" link. This in some ways
leads to a more consistent experience where you can zoom in on
any stream, even one that's really new.
This fix simplifies how we re-render topic lists when we
re-narrow or zoom out from a topic list.
* The topic_list.zoom_out() no longer gets called as
part of re-narrowing, and we eliminate the clear_topics
option.
* For all situations where we narrow to a filter that does
not have a topic, we simply call the new function
clear_topics().
* The stream_list code no longer calls remove_expanded_topics()
in cases where the new narrow has a topic. This allows us
to optimize away scroll/flicker churn a little more easily.
As part of this, we rename maybe_activate_stream_item() to
update_stream_sidebar_for_narrow(), since the function clears
stuff as well as turning stuff on.
This is mostly a pure code extraction. It makes the call
to reset_to_unnarrowed() happen later in sequence.
The order of operations here is mostly unimportant, but
there may actually be some tiny user-facing benefit
in terms of having the logic happen more sequentially.
BEFORE:
reset streams
fix top left
redraw streams
AFTER:
fix top left
reset streams
redraw streams
If you go into "more topics" for a stream with many topics,
and then scroll down, and then zoom out again with "All
streams", we make sure the active stream is still in view.
We have code that can automatically scroll an element into "view"
in its container. We use this for stream sidebar rows inside the
stream list.
Generally the stream sidebar rows are small enough to fit into
the container, and the prior algorithm worked correctly for that
scenario.
If you have lots of topics, however, and a short screen, the
algorithm was being too aggressive. For example, if the top
wasn't showing, it would scroll the top into view, but at the
cost of scrolling the bottom out of view.
This fix makes the general scrolling algorithm more tame.
Part of the user-facing problem is that the element we pass
into the scrolling code for the stream sidebar rows is bigger
than the part of the row that actually should be shown on
screen. Nevertheless, it makes sense here to make the general
algorithm more robust.
