This new helper allows us to do the same operation
on every message in our message_store. We will
use this in a future commit to clear the `is_tall`
flags on all messages, after a resize.
We should be somewhat cautious about using this,
but simple operations should be really fast, even
if you have lots of messages in the store.
This seems like a small change (apart from all the
test changes), but it fundamentally changes how
the app finds "topic" on message objects. Now
all code that used to set "subject" now sets "topic"
on message-like objects. We convert incoming messages
to have topic, and we write to "topic" all the way up
to hitting the server (which now accepts "topic" on
incoming endpoints).
We fall back to subject as needed, but the code will
emit a warning that should be heeded--the "subject"
field is prone to becoming stale for things like
topic changes.
This replaces some old code with calls to topic_data.js.
Now our topic typeahead uses the same data as our
sidebar, stream suggestions, and the "n" key, so any
future improvements to that data will benefit all
features the same.
This is an important piece of #9857.
This commit prepares the frontend code to be consumed by webpack.
It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.
However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.
So we expose the modules by setting window.varName = varName; as
needed in the js files.
This is a pretty pure code move, where we moved stuff from
message_store to pm_conversations:
insert_recent_private_message() -> recent.insert()
recent_private_messages -> recent.get()
The object message_store.recent_private_messages was not
encapsulated in a function before this change. Now it is
hidden in the scope of pm_conversations.recent.
Both of the modules touched here maintain 100% line coverage.
Once we convert message.flags to more specific boolean attributes
like message.mentioned and message.alerted, we should get rid of
the `flags` attribute, as it will only confuse debugging.
We no longer set message.flags in the local echo path.
In the markdown parsing step, we just set message.mentioned
directly.
And then we change `insert_new_messages` to no longer
convert flags to booleans, and move that code to only
happen for incoming server message events.
We want to call `set_message_booleans` as soon as we
get data from the server, to avoid confusion about whether
`flags` is the authoritative field.
This commit has callers to `add_message_metadata` call
`set_message_booleans`.
This also sets us up to **not** call `set_message_booleans`
in the local echo codepath, where we can just have the
markdown processor set booleans natively.
In all cases the value of `flags` we were passing in was
actually `message.flags` (although it was slightly obscured in
one place), so now we just pass in `message`.
(We also move a tiny bit of defensive code to set `flags`
into `set_message_booleans`.)
This logic used to be in extract_people_from_message(), but
we are deprecating extract_people_from_message(), whereas
the maybe_incr_recipient_count() function has logic that we
want to keep.
This never made sense to be a flag on the UserMessage table, since
it's not per-user state. And in fact it doesn't need to be in a
database at all, since it's easily computed from content anyway.
Fixes#1099.
Previously, we didn't check the organization-level settings when
rendering a message list; instead, we only checked it when putting
messages into the message_store. That resulted in the state being
stale in the event that the setting controlling whether one can edit
messages was changed.
We remove some node tests, because revidving the node test for their
new home in message_list_view would be more work than we probably want
to do with an upcoming release. We basically need to be better about
exporting functions like populate_group_from_message_container and
set_topic_edit_properties, so we can do fine grained testing.
When we get around to the node tests, rather than exporting these
functions, it might make sense to create a new module with a name
like message_container.js, which would have all of these
last-second type of data manipulations on message objects. This
would be nice to split out of message_list_view.js. MLV is our
biggest module, and it's mostly cohesive, but it's real job
should be about assembling messages into a DOM list, which is
probably 80% of the code now. The 20% that I'd want to consider
splitting out is actually closer in spirit to message_store.js.
Thanks to Steve Howell for helping with the node tests.
It's not always clear whether user_ids are strings or integers, so
we explicitly convert them to integers for sorting when creating
keys for PMs.
To keep the tests passing, this commit removes some unneeded
defensive code in message_store.js that only applies to contrived
test input.
We now call topic_data.add_message() and
topic_data.remove_message() when we get info about
incoming messages. The old way of passing in a boolean
made the calling code hard to read and added unncessary
conditional logic to the codepath.
We also have vague plans to change how we handle
removing topics, since increment/decrement logic is now
kind of fragile, so making the "remove" path more explicit
prepares us to something smarter in the future, like just
figure out when the last topic has been removed by calling
a filter function or something outside of topic_data.js.
Another thing to note here is that the code changed here
in echo.js is dead code, since we've disabled
message editing for locally edited messages. I considered
removing this code in a preparatory commit, but there's
other PR activity related to local echo that I don't want
to conflict with.
One nice aspect of removing process_message() is that
the new topic_data.js module does not refer to the legacy
field "subject" any more, nor do its node tests.
This new module tracks the recent topic names for any given
stream.
The code was pulled over almost verbatim from stream_data.js,
with minor renames to the function names.
We introduced a minor one-line function called stream_has_topics.
We no longer do the message_store piece of reifying ids
via a trigger. We now make an explicit call to an
ordinary function.
This has several benefits:
- no more initialize() function
- no more scary comments about garbage collection
- the function has a real name now
- the function is less indented
- we can easily see when the message_store step happens
- simpler node tests
- simpler tracebacks (no jQuery cruft)
In pm_conversations.js, added function to make a user a PM partner and
another function to check if a user is a PM partner. A PM partner is
someone with whom the user has been in a PM with.
In recent_senders module, added a data structure to hold timestamps of
users' latest message in a topic. Also added a function to compare 2
users based on above timestamp. Added a function to process messages for
the data structure and a call in add_message_metadata. Also added node
tests for insertion of data into recent_senders.senders.
After Iago changed his email, you would see strings like
"You and Iago, Cordelia," which was a consequence of looking up
Iago's full name using his old email. Now we use user ids
internally for the lookup.
We now call people.pm_reply_user_string to populate
message.to_user_ids. The old way of computing this used emails
instead of user ids, so if an email wasn't known, you'd get a
warning.
Before this fix, if you scrolled back in your PM history for a
person that you've had recent conversations with, then we would
backdate the record of their most recent conversation, and this
would make the sort ordering under the "Private messages"
section incorrect.
This commit fixes this error by re-writing the function
message_store.insert_recent_private_message() to check any
prior timestamps for that user. It also optimizes the function
a bit to short-circuit in O(1) time for cases where a recipient
already has a more recent timestamp, by having a Dict keyed
on user_ids_string.
This function is slightly easier to unit test, and it isolates us
from changing message formats. This removes some extraneous
code that would ensure that message timestamps were >= 0 that
probaby dates back to some really old migrations.
We have added people.pm_with_url(message), which computes a
PM url from a private message using user ids rather than emails.
We call this in add_message_metadata(), since the slugs will
be valid even if emails change, so we don't need to compute
them on the fly during message rendering.
We now trigger an event in user_events.js, and we dynamically
build the list of names in pm_list.js by calling out to
people.get_recipients().
We have a few variations of functions that build lists of names
for huddles, which should be cleaned up eventually. They are
called at different times in the code path, so the different
functions, while doing mostly the same thing, start with different
data sources.
This breaks the function
message_store.get_private_message_recipient into two functions:
get_pm_emails and get_pm_full_names.
The get_pm_emails function behaves the same way as the original
function, but get_pm_full_names now dynamically gets full names
from people.js using the user_id in the message.display_recipient
row.
This makes the recipient bar show the correct new name if you reload
your page. It doesn't help with live updates.
Pass down 'local_id' through functions that handle notifications for messages
that are sent locally. If 'local_id' is undefined, the message was not sent in
the respective tab, so no "outside_viewport" notification should be displayed.
This fixes#1783.
This commit replaces the placeholder "clipboard" button with a reaction button.
This is done on any message that can't be edited. Also, on messages sent by
the user the actions popover (toggled by the down chevron icon) contains
an option to add a reaction.
When clicked, a popover with a search bar and a list of emojis is displayed.
If the right sidebar is collapsed (the viewport is small), the popover is placed
to the left of the button.
Focus is set to the search bar. Typing in the search bar filters emojis.
Emojis with which the user has reacted to this message are highlighted.
Clicking them sends an API request to remove that reaction.
Clicking on non-highlighted emojis sends an API request to add a reaction.
When the popover loses focus it is closed.
The frontend listens for reaction events. When an add-reaction event is
received, the emoji is displayed at the bottom of the message with a
count initialized to 1. If there was an existing reaction to the message with
the same emoji, the count is incremented.
Old messages fetched from the server contain reactions.
They are displayed (along with title and count) at the bottom
of each message.
When clicking the emoji reaction at the bottom of the message, if the
user has already reacted with that emoji to this message, the reaction
is removed and the count is decremented. Otherwise, a reaction is added
and the count is incremented.
Hovering over the emoji reaction at the bottom of the message displays
a list of users who have reacted with this emoji along with the
emoji name.
Hovering over the emoji reactions at the bottom of the message displays
a button to add a reaction.
Fixes#541.
When editing a message changes the current narrow, we rerender the
narrowed view earlier in the function, so we don't need to do it here.
But we still need to rerender the home view, or the messages will be
displayed incorrectly once the user unnarrows!
Tweaked by tabbott for clarity and simplicity.
Fixes#2464.
