The previous query suffered from bad corner cases when the user had
received a large number of direct messages but sent very few,
comparatively. This mean that the first half of the UNION would
retrieve a very large number of UserMessage rows, requiring fetching a
large number of Message rows, merely to throw them away upon
determining that the recipient was the current user.
Instead of merging two queries of "last 1k received" + "last 1k sent",
we instead make better use of the UserMessage rows to find "last 1k
sent or received." This may change the list of recipients, as large
disparities in sent/received messages may result in pushing the
most-recently-sent users off of the list. These are likely uncommon
edge cases, however -- and the disparity is the whole reason for the
performance problem.
This also provides more correct answers. In the case where a user's
1001'th message sent was to person A today, but my most recent message
received was from them yesterday, the previous plan would show the
message I received yesterday message-id as the max, and not the more
recent message I sent today.
While we could theoretically raise the `RECENT_CONVERSATIONS_LIMIT` to
more frequently match the same recipient list as previously, this
increases the cost of the most common cases unreasonably. With a
1000-message limit, the common cases are slightly faster, and the tail
latencies are very much improved; raising `RECENT_CONVERSATIONS_LIMIT`
would increase the result similarity to the old algorithm, at the cost
of the p50 and p75.
| | Old | New |
| ------ | ------- | ------- |
| Mean | 0.05287 | 0.02520 |
| p50 | 0.00695 | 0.00556 |
| p75 | 0.05592 | 0.03351 |
| p90 | 0.14645 | 0.08026 |
| p95 | 0.20181 | 0.10906 |
| p99 | 0.30691 | 0.16014 |
| p99.9 | 0.57894 | 0.19521 |
| max | 22.0610 | 0.22184 |
On the whole, however, the much more bounded worst case are worth the
small changes to the resultset.
Fixes#26774.
We don't need the today argument anymore since every value passed to
it was a new Date() except the tests where we are using MockDate now.
Added handlebars if-else conditions to display
'User is deactivated' tooltip for deactivated users
and 'Bot is deactivated' tooltip for deactivated bots.
Fixes#28593.
This is preparatory work towards adding a Topic model.
We plan to use the local variable name as 'topic' for
the Topic model objects.
Currently, we use *topic as the local variable name for
topic names.
We rename local variables of the form *topic to *topic_name
so that we don't need to think about type collisions in
individual code paths where we might want to talk about both
Topic objects and strings for the topic name.
Merges the two charts remaining to have just one chart for the
realm activity view.
Removes the columns for different clients and adds a column to
show/sort by the user type (human or bot type).
Deletes templates/analytics/activity.html because it is no
longer used for any activity pages/views.
Removes the summary tab/chart from the user activity view.
Moves get_user_activity_summary from common_activity.py to
realm_activity.py since it's no longer used in the user
activity view.
Updates the title of the page to incluce the realm name since
an email address may be used for multiple user accounts.
Earlier, after a successful POST request on find accounts page
users were redirected to a URL with the emails (submitted via form)
as URL parameters. Those raw emails in the URL were used to
display on a template.
We no longer redirect to such a URL; instead, we directly render
a template with emails passed as a context variable.
Fixes part of #3128
There were two typeahead displayed while we were testing
create_private_message_draft. One was topic typeahead from previous
create_stream_message_draft test and the other was cordelia
DM typeahead. So, when clicking on the typeahead, we clicked
the topic typeahead when we really wanted to select the cordelia
typeahead. This resulted in drafts test failing.
When you click "Plan management", the desktop app opens
/self-hosted-billing/ in your browser immediately. So that works badly
if you're already logged into another account in the browser, since that
session will be used and it may be for a different user account than in
the desktop app, causing unintended behavior.
The solution is to replace the on click behavior for "Plan management"
in the desktop app case, to instead make a request to a new endpoint
/json/self-hosted-billing, which provides the billing access url in a
json response. The desktop app takes that URL and window.open()s it (in
the browser). And so a remote billing session for the intended user will
be obtained.
All message view has `in-home` filter and is not empty.
If there are no terms provided, we set filter to display
all messages (including muted streams/topics).
We make it mandatory to provide terms to Filter.
All messages list always has the "in-home" filter. We are in the
process of removing "zhome/zfilt" from message list, so this would
help in that process.
