The selector we were passing to `condense_and_collapse`
included rows from our drafts UI, which don't have
zids and don't play nice with condense/collapse code
(which expects message ids for settings things like
`.condense` flags).
Now we just use a better selector.
If folks use an overly broad selector for message rows,
they will accidentally include drafts from the drafts
dialog, which won't have zids. More specific selectors
will be more efficient and possibly prevent strange
behaviors.
For testing convenience, we extract the message.
We now handle the esc key completely within the
keydown handler that we already have for message
editing. We allow escape to work no matter what
the focused element is within an edited message,
and we blur that element properly and end the
edit.
We remove all the strange, duplicated logic
from hotkey.js.
This should also fix a blueslip error where the
hotkey code was passing message_edit a jQuery
element with zero length.
Fixes the traceback reported in #14151, though we should still look at
the DOM cleanup discussed there.
The UI in the `#settings/notifications` page is updated similarly
to what is done in the `update_global_notifications` path present
in the `server_events_dispatch` file.
We have an alert for when the stream name is changed.
This also adds an alert when subscription settings
are updated and the widget is similar to that used in
the settings page.
This is also necessary because the stream specific
notification settings UI updation goes through this
path and it is necessary to display a confirmation
to match with other settings confirmation pattern.
Since each element containing the `.alert-notification`
class has a predefined area that wont overlap with any
other element, we make changes to the CSS so that it
just stays hidden until the text appears.
This setting is being overridden by the frontend since the last
commit, and the security model is clearer and more robust if we don't
make it appear as though the markdown processor is handling this
issue.

While we could fix this issue by changing the markdown processor,
doing so is not a robust solution, because even a momentary bug in the
markdown processor could allow cached messages that do not follow our
security policy.
This change ensures that even if our markdown processor has bugs that
result in rendered content that does not properly follow our policy of
using rel="noopener noreferrer" on links, we'll still do something
reasonable.

If we can't find data on a mentioned user to update its full_name to
the current value, we'll have to go with the value in the message
itself.
This can happen if e.g. we hard-deleted the originally mentioned user
from the database (which can sometimes happen after a "delete my
account completely" request).
The user has an option for setting global
notification settings as well as the same settings
for individual streams. Currently the user has to
keep track of each unmatched stream and then visit
each individual stream whose settings he wants to
update.
Thus this adds a dedicated UI table allowing the user
to view and update the notifications of the specific
streams which differs from the global settings.
It is located on the same page where the user defined
global notification settings can be modified.
Fixes#9228.
Currently we are updating the checkbox UI as soon as the user clicks.
This block is removed to match with the pattern of rest of the
properties in the stream edit page where `stream_events.update_property`
is responsible for updating the UI after a successful server response.
This function returns a list of objects to create a
list_render object, and each item contains the streams
whose atleast one notification setting differs from the
default set by the user.
This is done by comparing the global settings in the
`#settings/notifications` page with those settings
present in the subscribed streams.
Work towards #9228.
This flag was used to delay unread count updates while the bankruptcy
modal was visible. Now that bankrupcty is no longer a modal, we don't
need this flag at all.
Switched to top-of-page prompt to make it natural to fit in with other
notifications. As we switch to panel-based prompt, templates for the
bankruptcy modal are moved along with its usage in application's
homepage.
We include a bit of delay before reloading to make it easy for the
user to read the "Marking all messages as read" banner before it is
covered by the "Reloading..." notice in environments where the reload
is fast.
Fixes#3347.
When stream_post_policy modal is closed either after saving or using
cancel button or cross button, the pointer-events is set to none which
does not allow to close the stream settings overlay on one click.
Added overlay.close_modal on saving such that pointer-events:none is
removed.
Added line which removes pointer-events:none again on clicking cancel
button or close icon.
This is a prep commit which extracts the part of the code in open_modal
and close_modal to separate methods which adds inline style of
pointer-events to enable/disable the background mouse events.
Block comments are added for easy understanding of reader.
This commit removes "font-weight: 500;" from landing-page.scss so as
to fix a bug on landing pages that used the `markdown` class to
format content. The bug was caused by "a:hover" from landing-page.scss
overriding the font-weight (600) on links as set by the markdown
class, this caused the text to seem jumpy when one hovered over links.
Note from tabbott: The original code was added in
d7f5f31f6a, which doesn't explain it's
purpose, but it predates the more complete "markdown" CSS, was part of
an early prototype that had unfortunate hover behavior more generally,
and makes sense to remove.

The previous system for documenting arguments was very ugly if any of
the examples or descriptions were wrong. After thinking about this
for a while, I concluded the core problem was that a table was the
wrong design element to use for API parameters, and we'd be much
better off with individual card-type widgets instead.
This rewrites the API arguments documentation implementation to use a
basic sort of card-like system with some basic styling; I think the
result is a lot more readable, and it's a lot more clear how we would
add additional OpenAPI details (like parameter types) to the
documentation.
The previous logic avoided updating the setting for
non-administrators, because their value was always true, but removing
those if statements results in better test coverage and is more likely
correct if we ever try to support live-update for whether the user is
an administrator.
We've noticed that many production organizations don't set either an
organization description or profile picture, even large open source
organizations that could definitely take advantage of this feature.
This adds a top-of-page banner that bugs organization administrators
to add an organization description and profile picture, generally
starting on the second login (as we only do it on page load after
notifications are configured).
Significantly tweaked by tabbott to get the right user experience.
Fixes#14019.
The original implementation of panels.js was just for notifications,
and ended up running a bunch of notifications-specific code, including
registration click handlers and some localstorage-related
notifications logic, every time a panel was supposed to be opened.
This refactoring makes the panels library make sense -- we now
initialize all click handlers in the initialize() method, and do the
notifications check in a single, coherent place scoped to notifications.
Commit 68335d9124 removed the ability to tab
into this field, since it was a hidden field. This field is no longer
hidden, and this commit restores the ability to tab into it.
In continuation to #13250
CHANGES:
-the stream name edit button is now visible for long names too.
-ellipsis are removed when you click on edit name option.
-added border while editing name to give a text-box feel.
REASONS:
-added border while editing the name to give a textbox-esque feel.
-text overflow was changed from ellipsis to clip (while editing) as
ellipsis prevented editing the entire name (clip provides better
functionality).
The last two changes are reverted back to original (i.e. ellipsis and
no border) once you finish editing the stream name.
P.S.- clicking on anywhere else updates the new name perfectly
Here we have migrated checkboxes of all general notifications to the table.
By general notifications we mean, Mobile, Email, Desktop audio, and visual
notifications.
This is a part of a bigger migration to simply our notifications setting
changing infrastructure for all streams and individual streams. Later we
will add more row to this for different categories of notifications in
addition to the current ones ("Streams" and "PMs, mentions, alerts").
Fixes: #12182.
When you select a typeahead, it shouldn't
immediately do the action for you; you should
have to hit enter first. Even though 99% of
the time you're gonna confirm the typeahead,
it's jarring when you don't expect it.
You can still add a bunch of default streams
quickly, using only the keyboard, because
we have always had support for the enter
key saving. (and tab and enter also works)
This is a full-stack change:
- server
- JS code
- templates
It's all pretty simple--just use stream_id instead
of stream_name.
I am 99% sure we don't document this API nor use it
in mobile, so it should be a safe change.
We now only use `page_params.realm_default_streams` during
initialization, and then after that we use `stream_data`
APIs to get default stream ids and related info. (And
for the event that replace the data, we just update our
internal data structures as well.)
Long term we should have the server just send us ids here,
since we are now hydrating info from stream data in all places.
This code is a bit simpler.
The previous code was concatenating two lists
and then removing duplicates by calling filter().
Now we just have two loops that append to a single
list, and the second loop detects duplicates
before inserting into the list.
We also now use `default_stream_ids` instead of
`page_params` data, which is convenient for two
reasons:
- working with sets of ids is convenient
- we don't need to maintain `page_params`
data any more
We now use the up-to-date info from stream_data
to hydrate the default stream ids. All we need
here in the template is `invite_only` and `name`.
Since we are no longer using data from `page_params`,
we can remove `maybe_update_realm_default_stream_name`.
(If you are wondering if we still get live updates,
we get that via a more upstream call to
update_default_streams_table in the event
dispatching codepath.)
We only used get_default_stream_names() in a
test, so now it's being replaced with a function
that just gets ids.
We'll have use for get_default_streams_ids()
in an upcoming commit.
Now if a default stream gets deleted, we just
redraw the table. We always have a small number
of default streams, and the way that we were removing
rows without the actual consent of `list_render` was
really janky (and just a vestige of pre-list-render
code that never got fully ported).
This also makes us consistent with how we handle
added streams (i.e. just call
`update_default_streams_table`).
ASIDE:
Ideally we will update `list_render` at some point to
have an API for adding and removing elements. It does
allow you now to call `data()` to reset its data, but
for now we just build a new `list_render` object every
time.

We stopped needing this with
0329b67048
(Dec 2016).
The function sets `bot.can_admin`,
which was only used in `bot_data.get_editable`.
We removed two tests (and then put back
some test setup that needed to leak down
to the last test).
This is code simplification motivated
by a recent bug that we fixed with some
server changes, but which was really
caused in some sense by our client code
using an overly finicky
condition to check falsiness.
For cross-realm bots, the value of
`user.bot_owner_id` may be `null`, or it
may simply be `undefined`, depending
on whether the server passes `None`
or simply omits the field.
We don't want out client code to be
coupled to that rather arbitrary
decision.
We were doing a `!== null` check instead
of checking for falsiness, which led to
blueslip errors in the past. Because a
bot owner id could be plausibly 0, a falsiness
check would be brittle in a different way.
Now we avoid that ugliness by calling
`get_bot_owner_user`, which either returns
an object or `undefined`.
And then the caller can just do a concise
check for whether `bot_owner` exists.
And we also fix up the crufty code that
was putting `bot_owner_full_name` on to
the object instead of using a local.
We have a bug report for this again, although
it might be on an old branch.
Fixes#13621.
This allows us to block use of the desktop app with insecure versions
(we simply fail to load the Zulip webapp at all, instead rendering an
error page).
For now we block only versions that are known to be both insecure and
not auto-updating, but we can easily adjust these parameters in the
future.
We know that by default the value of `enable_stream_push_notifications` is
true, so on some server if push notifications are disabled then due to
```
{{#unless show_push_notifications_tooltip}}
```
the `enable_stream_push_notifications` checkbox is rendered as unchecked
and when we update any other setting in the "Stream notifications" section,
due to `settings_notifications.update_page()` all checkboxes are changed to
current values which means above checkbox get checked.
We can deal with this bug either making changes in
`settings_notifications.update_page()` but we should show check/uncheck
state of checkboxes anyway so removing this `unless` condition fixes this
bug.
Instead of having logical expressions in templates, it's always preferred
to calculating them in javascript and pass the results as a context. It
also enhances the readability of templates and testing of such logic is
easier in js over templates.
`all_notification_settings_labels` is misleading that this variable is a
list of notifications setting labels so changed it to
`all_notification_settings`.
The reason for extracting this function is that getting the text, integer,
boolean value from the input elements (like checkboxes, dropdowns) is a
common task, and later we can use this function to get the input element
value in `settings_notifications` in the upcoming commit.
This is a bug fix where, if a list_render
object with the given name exists and it's items
have been sorted, then the filtered_list's data
does not get updated on re-rendering.
This line was present in the original commit
9576d5caef.
The use case for this are small or fixed tables, which do not need
filtering support. Thus we are able to not include the unnecessary
search input inside the html parent container.
It is not used at present, but will be required when we refactor
the settings pages.
We also split out exports.validate_filter function for
unit testing the above condition.
As a consequence of too many options in the bottom `Other permissions`
subsection, the `Save` button could end up too far up from the bottom,
such that it might appear offscreen on low-height laptops.
We fix this by reorganizing the settings in a way that is both more
intuitive and also ensures that none of the subsections are too tall.
Fixes: #14274.
Before this commit, the reactions code would
take the `message.reactions` structure from
the server and try to "collapse" all the reactions
for the same users into the same reactions,
but with each reaction having a list of user_ids.
It was a strangely denormalized structure that
was awkward to work with, and it made it really
hard to reason about whether the data was in
the original structure that the server sent or
the modified structure.
Now we use a cleaner, normalized Map to keep
each reaction (i.e. one per emoji), and we
write that to `message.clean_reactions`.
The `clean_reactions` structure is now the
authoritatize source for all reaction-related
operations. As soon as you try to do anything
with reactions, we build the `clean_reactions`
data on the fly from the server data.
In particular, when we process events, we just
directly manipulate the `clean_reactions` data,
which is much easier to work with, since it's
a Map and doesn't duplicate any data.
This rewrite should avoid some obscure bugs.
I use `r` as shorthand for the clean reaction
structures, so as not to confuse it with
data from the server's message.reactions.
It also avoids some confusion where we use
`reaction` as a var name for the reaction
elements.
We've often gotten the complaint that Zulip's emoji are a bit too big;
this should address the worst consequences of that (line-wrapping
being off with large emoji present) while still making it possible to
easily see what a given emoji is.
The right place to change this is in rendered_markdown.scss, not the
main emoji definition in zulip.scss, as the latter is also used in
places like the emoji picker where a larger size is valuable.
Closes#12731, an older PR that did this with slightly different
parameters (and without a comment).

You can test this on dev:
* do "-stream:Verona" in the search bar (the minus
sign negates the search here)
* reload the browser
You should see the same search (all streams besides Verona).
We simplify the code for deciding whether
we show a subscribe button or not, and in
doing so avoid a blueslip error where we
were passing `undefined` into `get_sub()`.
We had this API:
people.add_in_realm = full-fledged user
people.add = not necessarily in realm
Now the API is this:
people.add = full-fledged user
people._add_user = internal API for cross-realm bots
and deactivated users
I think in most of our tests the distinction between
people.add() and people.add_in_realm() was just an
accident of history and didn't reflect any real intention.
And if I had to guess the intention in 99% of the cases,
folks probably thought they were just creating ordinary,
active users in the current realm.
In places where the distinction was obviously important
(because a test failed), I deactivated the user via
`people.deactivate`.
For the 'basics' test in the people test suite, I clean
up the test setup for Isaac. Before this commit I was
adding him first as a non-realm user then as a full-fledged
user, but this was contrived and confusing, and we
didn't really need it for test coverage purposes.
We want to move more logic to stream_data to facilitate
testing.
Both before and after this commit, we essentially build a
new list of users for typeahead, but now the new list
excludes subscribed users. We can do even better than
this in a follow-up commit.
Before this commit, presence used get_realm_count()
to determine whether a realm was "small" (and thus
should show all human users in the buddy list, even
humans that had not been active in a while).
The `get_realm_count` function--despite a very wrong,
misleading comment--was including bots in its count.
The new function truly counts only active humans
(and no bots).
Because we were overcounting users before this change,
we should technically adjust `BIG_REALM_COUNT` down
by some amount to reflect our original intention there
on the parameter. I'm leaving it alone for now, though,
since we've improved the performance of the buddy list
over time, and it's probably fine if a few "big" realms
get re-classified as small realms (and show more users)
by virtue of this change.
(Also note that this cutoff value only affects the
"normal" view of the buddy list; both small realms
and large realms will show long-inactive users if you
do searches.)

This is a prep commit for the new navbar, since the new navbar switches
between a search bar and stream descriptions, it's easier to have the

navbar.html is to add an opening div with the ".top-navbar-border" class

Given that can_mark_messages_read is called whenever the blue box
cursor stops on a message and that it is calculated purely on the
basis of sorted_term_types, it makes sense to cache the result.
Previously, when list_render.create was called, if a list_render
object with the given name existed, it returned the existing
list_render object with the previous properties, without the property
to sort the lists added. The root cause of the bug was that when we
added the sorting click handlers, we put them just in the constructor,
not in __set_events, the function we call from appropriate code paths
to add the other necessary click handlers.
Fix this by moving the code to add the sorting properties into
__set_events().

Original email address is shown to admin users in subscriber list when
email_address_visibilty is set to "Admins only" by passing delivery_email
at required places. Email address are not shown to non-admin users when
visibility is set to "Admins only".
Tweaked by tabbott to fix a few bugs and dead code.
Fixes a part of #13541.
User IDs are more robust than email addresses as they don't change
with time, and also don't have complications with
different email_address_visibility settings.
This is a common UX pattern for forms - a user would expect the
input to be submitted on hitting enter.
So, create a 'keypress' event listener on the input field for the
new status, which calls 'submit_new_status' on enter key press.
This intent is that we'll be able to reuse this when editing streams
as well.
* Rename method: filter_with_new_topic to filter_with_new_param.
* Fix tests and method calls.
This extends our email address visibility settings to deny access to
user email addresses even to organization administrators.
At the moment, they can of course change the setting (which leaves an
audit trail), but in the future only organization owners will be able
to change that setting.
While we're at this, we rewrite the settings_data.js test to cover all
the cases in a more consistent way.

Currently, the cursor for the date input field in the settings page
is 'not-allowed' as it has the disabled attribute because we want
users to pick the date from the date picker. But this leads to
confusion whether the field is editable at all.
Change the cursor to 'pointer' to make it clear that the field has
a click action associated with it.
Clicking on the 'Owner' value for a row in the list of bots does
nothing, and causes a blueslip error.
This is because the map object in which we store the users have
integer keys, while we pass the owner id as string.
This is fixed by parsing the owner id to integer before passing it
on.
Fixes#14107.
The file populates `windows.i18n`, so now
the file name matches our convention.
Note that the module really just initializes
`i18next` and then does this:
window.i18n = i18next;
It doesn't really add any functionality to
third party library.
Before 2018, we used a feature of i18next where
we would cache translations in local storage
for up to two weeks:
var cacheOptions = {
// ...
prefix: 'i18next:' + page_params.server_generation + ':',
expirationTime: 2*7*24*60*60*1000, // 2 weeks
};
i18next.init({
/// ...
cache: cacheOptions
}
Because `server_generation` would change each time you
upgraded a server, a frequently upgraded server like
chat.zulip.org would cause its active users to start
to accumulate lots of obsolete key/value pairs in local
storage over the two weeks.
See #4443 for more details.
We eventually reduced the cache life to 2 days. And then
on top of that, newer versions of the server would start
to clean up after themselves using this commit from
April 2017:
e3f1d025ae
We then removed the caching option altogether a year
later in May 2018:
cff40c557b
We kept around the code to remove all the old keys, though.
This was particularly important for users who may have
been hitting servers that did an upgrade to the new
version from some older version that didn't have the
key-fixing code.
But mostly the problem takes care of itself after
either two days or two weeks, even on really out-of-date
servers.
The original problem was most likely to affect server
admins that did a lot of upgrades (and possibly only really
affected chat.zulip.org), so as long as those server
admins continued their patterns, it's highly likely that
they've done several upgrades since May 2018 that would
have cleaned these keys out for good.
And, again, even if there is some strange straggler here,
they probably only have one set of keys that will expire
either two days or two weeks after an upgrade, depending
on how long ago the prior upgrade was. (All of their
keys based on older versions of `server_generation` would
have long since expired.)
Finally, any upgrade certainly won't make the problem
worse for any users under this hypothetical situation,
since the new server won't be writing new keys.
So I am removing the cleanup code.
This extracts a new module with three
functions, which we will test with 100%
line coverage:
- show_email
- email_for_user_settings
- get_time_preferences
The first two break several dependencies
in the codebase on `settings_org.js`. The
`get_time_preferences` breaks an annoying
dependency on `page_params` within people.
The module is pretty cohesive, in terms that
all three functions are just light wrappers
around `page_params` and/or `settings_config`.
Now all the modules that want to call show_email()
only have to require `settings_data`, instead of
having a dependency on the much heavier
`settings_org.js` module.
I also make some of the unit tests here be more
full-stack, where instead of stubbing show_email,
I basically just toggle `page_params.is_admin`.
Users who are using ZulipDesktop or haven't managed to auto-update to
ZulipElectron should be strongly encouraged to upgrade.
We'll likely want to move to something even stricter that blocks
loading the app at all, but this is a good start.
This follows the convention of other code calling into
add_sub_to_table of checking whether the stream settings overlay is
open (and thus in the DOM) before trying to rerender it.
This fixes a bug where you can’t open the same overlay twice in a row
in IE 11, which doesn’t support HashChangeEvent.oldURL; it was exposed
by commit 05be16e051 (late 2018).
While here, parse the hash from oldURL in a less ad-hoc way.

We add these two functions to the API,
so that we no longer have `alert_words_ui`
using private data from `alert_word`:
alert_words.has_alert_word()
alert_words.get_word_list()
And to initialize the data, we have a proper
`initialize` method that is passed in only
the parameters that it needs from `ui_init`.
(We also move the step of deleting `alert_words`
from `page_params` to the `ui_init` module.)
Because it's a bit less cumbersome to initialize
`alert_words`, we now just it directly in the
node tests for `alert_words_ui`.

This cleans up the handoff of page_params
data between ui_init and modules that
take over ownership of page_params-derived
data.
Read the long comment in ui_init for a bit
more context.
Most of this diff is actually test cleanup.
And a lot of the diff to "real" code is
just glorified `s/page_params/params/`
in the `initialize` functions.
One little oddity is that we don't actually
surrender ownership of `page_params.user_id`
to `people.js`. We could plausibly sweep
the rest of the codebase to just use
`people.my_user_id()` consistently, but it's
not a super high priority thing to fix,
since the value never changes.
The stream_data situation is a bit messy,
since we consume `page_params` data in the
initialize() function in addition to the
`params` data we "own". I added a comment
there and intend to follow up. I tried
to mostly avoid the "word soup" by extracting
three locals at the top.
Finally, I don't touch `alert_words` yet,
despite it also doing the delete-page-params-data
dance. The problem is that `alert_words`
doesn't have a proper `initialize()`. We
should clean that up and have it use a
`Map` internally, too.
This gives them cache-compatible URLs, and also avoids some extra
copies of the sprite sheet images.
