Based on extensive manual testing with print-debugg (the exact
situation here was highly reproducible), in the absence of this line
here or slightly above here, Chrome 64 will consistently trigger an
extra scroll-forward-by-12000-pixels size downward scrolling event
immediately after it finishes rendering the 5th batch of ~100 messages
one gets from hitting the End key in `near:1` narrows.
I don't understand clearly why this change would protect against such
a Chrome bug, but my best guess is that Chrome was doing some sort of
incorrect optimization, and querying the scrollTop was forcing it to
come to a clear conclusion about the scrolling position before
appending more content.
But runs with the scrollTop() line not present in that function show a
scrollTop of around 25K in `append()` just before the call to
`render()`, and 37K at the end; while runs with this scrollTop line
always show 25K both before and after, so it does seem to work.
We don't have any consumers for this event after removing
some obsolete code related to subscribe buttons.
Handling this event reliably consumed about 75% of the time
spent in _post_process_dom_messages, and maybe a percentage
point or two of overall rendering, so this will be a minor
speedup.
Applies the logic to allow community members to edit topics
of others' messages if this setting is True. Otherwise,
only administrators can update the topic of others' messages.
This logic includes a 24-hour time limit for community topic editing.
In `recipient-row` template, if conditions to add/hide/show edit
icon for message topic is incorrect.
In some cases, we only want to just hide the edit icon, but icon
should be in DOM, cause in future if organization settings are
changed we want to show edit icon in message row.
If user can edit topic of message, surely add edit icon element to
DOM regardless of user is allowed to edit or not. If user is
allowed to edit then show edit icon otherwise hide edit icon element.
We no longer have a special UI setting and model
field ("emoji_alt_code") for saying users want text-only
emojis. We now instead make "text" be a fifth choice
for "emojiset".
Fixes#7406
This change has a few cleanups:
* We early-return on last_msg_container === undefined
to make the function flatter.
* We avoid comparing two boolean values for equality,
which can be a landmine if one of the values is
`undefined`, which is falsy but not actually `false`.
* We extract some local variables for readability.
* We make the conditions for subscribe/unsubscribe
more explicit.
Do not attempt to autoscroll down to view new messages if popovers are
open. This prevents the issue where someone can be viewing a profile or
reacting to a message and not be able to due to a new message coming in.
Fixes: #7319.
When we added support for mentioning users when editing messages, we
neglected to add this bit of code needed to make sure the UI code in
message_list_view.js would actually rerender that part of the
message's state.
Arguably, this is a sign that the message_container structure should
be just recomputed every time we rerender messages, but that's a less
tactical fix.
We've been getting reports for a few months of folks coming back to
their Zulip window after a night's sleep and finding it scrolled to
the bottom, past dozens or hundreds of messages that they haven't
read. Oddly, the pointer is actually still located where it should be
(verifiable by hitting the Up key), but it's too late: everything
below gets marked as read because bottom_whitespace is in view.
There's only a few places in the zulip codebase where we scroll the
page down, and this is the main one of them. My best theory for what
could be happening is that the browser is, in its overnight
power-saving mode, not granting the Zulip window the resources to
actually repaint the early scrolls. This, in turn, would cause
scrolling down to happen that is not limited by the need to keep the
pointer in view.
I don't think that this fully closes the issue; ideally, we'd have a
reproducer and much more precise detection logic for this situation,
but it should mostly resolve the problem with likely no user-facing
visible harm.
We had a bug where once you scrolled back far enough
in the message view, your "window" for rendered messages
would be at the max, and `prepend` was not adjusting
the window correctly. Now we follow the example of
`append` and call `maybe_rerender`.
This partially addresses #6628, where users were
reporting that the home key stopped going up in their
feed. There was another bug at play for that issue
as well, which is fixed in the next commit.
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.
By the time we render messages, we will have set message.unread,
so we don't need to calculate it from flags.
We add a line to the local-echo path to make this explicit
in that code.
Previously, if we had both a date and a subscribe bookend, they would
appear in one order after new messages were sent (bookend_bottom of
the top group), and another after a reload (bookend_top of the bottom
group). This makes the experience consistently a bookend_top.
When receiving the first new message of a new day, we were previously
not showing a date separator line before the message.
Fixes a regression introduced
in 00c7f7d42f.
Despite the length of this commit, it is a very straightforward
moving of code from narrow.js -> narrow_state.js, and then
everything else is just s/narrow.foo()/narrow_state.foo()/
(with a few tiny cleanups to remove some code duplication
in certain callers).
The only new functions are simple setter/getters that
encapsulate the current_filter variable:
narrow_state.reset_current_filter()
narrow_state.set_current_filter()
narrow_state.get_current_filter()
We removed narrow.predicate() as part of this, since it was dead
code.
Also, we removed the shim for narrow_state.set_compose_defaults(),
and since that was the last shim, we removed shim.js from the app.
This fixes a regression in 3041480600
that would cause anything rendered on the backend differently than on
the frontend to experience this animation.
We actually only want to do the animation when the message content was
changed in a way that generates an edit history event, i.e. a
user-facing edit, not in cases where we're either transparently
swapping in post-backend-rendering content (e.g. with link previews)
or cases where there's a discrepancy between the exact HTML from the
frontend and backend markdown processes (e.g. mentions).
When a message update comes back from the server and replaces an
old message, it should fade in. There are two components to the fade:
1. The message fades in from opacity: 0 => 1.
2. The "edited" text will transform from X: -10 => X: 0.
This fixes a bug where newly received very-long messages would only
sometimes be collapsed properly until a second message arrived
(whether it did the right thing dependened on whether the new message
had the same recipient or a different recipient from other arriving
messages).
Apparently, we correctly called condense.condense_and_collapse in all
but one of the codepaths of `render` that add new messages. This
adds a call on the missing codepath.
Fixes#3978.
This fixes the mobile web experience for Chrome on iOS.
Apparently, Chrome-on-iOS silently has a `viewport` module that
overrides and user-defined module by that name, causing all of our
code that accesses the viewport module to not work on that platform.
We fix this by renaming it.
Like the topic edit pencil icon, the new UI is mostly invisible, but
appears when you hover over the recipient bar.
* Added a tag to hold the mute button in recipient_row.handlebars with
corresponding styling in zulip.css.
* Added an event handler for the mute button in click_handlers.js.
Fixes: #2235.
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.
The local echo code now marks up mention buttons with user ids
instead of email. Our code in message_list_view.js deals with
either the old style or the new style of markup now to determine
which mention buttons need to be highlighted.
As part of this commit we extract mention_button_refers_to_me().
This shows a date on a message header whenever the date of that
message is different than the date of the previous message.
The previous logic was bugged and didn't display dates in headers at
date transition points.
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.
This fixes a bug where Zulip would throw a TypeError if the user were
to try to narrow to a stream they had never been subscribed to. With
the new "preview" feature on the subscriptions page, this will now
happen much more often.
