Some uploads can be rejected in the frontend, like when the file
size is too big, without sending the file to the server. Remove the
'Uploading file...' message from the compose box in such cases.
Now, the system uses word='' and an editing=True for rendering an
form for addition of alert words. This is a very vulnerable
way to implement said feature and this commit fixes that.
The addition form has been moved to alert_word_settings.hbs
thereby rendering it only once but always. Now, we do not have
to manually add an empty word and editing for the form to be
rendered.
As part of refactoring, the editing parameter has also been
removed as there is no purpose left.
This change allows us to align the search icon to the right end of the
navbar, without having to rely on the `margin-left: auto` trick. This
is better because it's more convenient to let flex handle the
positioning and will, hopefully, be more resilient to breakages.
The motivation behind this change is that it is more sensible to have
search_icon styles appear first and then be overridden by
search_closed or search_open styles which appear afterwards. This is a
prep commit to correcting a bug that caused some browsers to
render the width (and hence margin and position) of search_closed
incorrectly.
This updates the logged-in top navbar to display the stream/message
name, number of users, and description. It also replaces the search
bar with a search icon that expands into a full-width search bar.

Fixes: #164.
Fixes: #5198.
In ee0d4541b4, we renamed the topic_date
-> stream_topic_history, and in the process renamed some local object
properties from .name => .topic_name, and accidentally change the
type for the data from the server as well.
The test fixtures were incorrectly migrated in the same way, so we fix
that as well.
While Hovering over some cell of the tables in settings Tab
increase the cell width since we are using the pseudo-Element `:: after`
the bug is fixed by adding `position: absolute;`.
fixes#14559
The disabled property actually prevented text selection, so it seems
better to use CSS through the `readonly="readonly"` property.
For this, swapped .prop() with .attr() since .prop() was setting it as
`readonly=""`.
`stream_topic_history` is a more appropriate name as this
module will contain information about last message of a
stream in upcoming commits. Function and variable names
are changed accordingly like:
* topic_history() -> per_stream_history()
* get_recent_names() -> get_recent_topic_names()
* name -> topic_name
If a file cannot be added for upload because of restrictions in frontend
we call cancelAll immediately in 'info-visible' callback. This would
prevent files that are already added to be cancelled but does not cancel
files that are yet to be added. So we use break to prevent any more files
from being added.
Calling uppy.cancelAll() when a batch of uploads is completed
result in the cancelation of any other batch of uploads that is
in progress. This case happens when a user uploads some files
and then tries to upload another bunch of files before the existing
upload is completed.
Removed the condition in the settings_save_discard_widget page which
allowed the page to be rendered only for admins. This change was
important so that this widget can be used on the user settings page
for displaying confirmation messages.
For non-admins, trying to access admin-only settings, behaviour remains
the same as before as these settings are disabled for non-admins.
The form for entering alert words has been moved above the list
of words.
The list of words will be presented alphabetically rather than
time of addition.
This refactors add_default_stream in zerver/views/streams.py to
take in stream_id as parameter instead of stream_name.
Minor changes have been made to test_subs.py and settings_streams.js
accordingly.
Added UI support for uploding the new profile picture by
clicking on the avatar rather than a button.
Added new spinner for loading indication while uploading
a new avatar over the avatar area.
Fixes#10255
The original commit here was sorting bot owners by
id, which is of course meaningless to users:
444ce74a8e
It was also returning 1/-1 in cases where the bot
owner on both sides of a comparison were missing,
which is a big no-no for sorting algorithms.
We want to avoid creating jQuery objects that just
get turned right back into strings by the list
widget, so we now have our template just include
`last_active_date` instead of kludging it in
after the fact, and we return the template
string in `modifier` rather than wrapping it.
To deal with plain HTML we switch to using
`render_now`.
Calling `render_now` leads to a more simple
codepath than `render_date`, beyond just dealing
with text.
The `render_date` function has special-case logic
that only applies to our time dividers in our
message view, which is why we were passing the
strange `undefined` parameter to it before this
fix.
The `render_date` function was also putting
the dates into `update_list` for once-a-day
updates, which is overkill for an admin screen.
We don't use this logic for drafts or attachments
either. I'm not sure how well tested that logic
is, and it's prone to slow leaks.
This commit sets us up to simplify the list
widget not to have bit-rot-prone code related
to jQuery objects.
We now:
- Skip the broken "Never" case. (The way
we were distinguishing "Unknown" from
"Never" was based on brittle checks that
were just wrong due to bitrot--see Steve
Shank on czo as an example. If we want
to make this distinction rigorous in the
future, we should have a clear mechanism.
If somebody's never actually been active,
we probably want to treat that more like
a dead-on-arrival login, anyway, and make
it easy to clean them up.)
- Use the `presence.last_active_date` instead
of reaching into private data structures.
- Avoid the unnecessary intermediate constants
of LAST_ACTIVE_NEVER and LAST_ACTIVE_UNKOWN.
- Avoid setting `last_active` in `populate_users`.
This commit was modified by @showell:
- I cleaned up the commit message.
- I simplified the diff a bit to avoid
some renaming and lexical moves.
We already know which list widget a `<th>`
tag is associated with when we set up the
event handler, so it's silly to read data
from the DOM to find that widget again
when the handler runs.
This commit eliminates a whole class of possible
errors and busy work.
For some widgets we now avoid duplicate redraw
events from this old pattern:
widget = list_render.create(..., {
}).init();
widget.sort(...);
The above code was wasteful and possibly
flicker-y due to the fact that `init` and
`sort` both render.
Now we do this:
widget = list_render.create(..., {
init_sort: [...],
});
For other widgets we just clean up the need
to call `init()` right after `create()`.
We also allow widgets to pass in `sort_fields`
during initialization (since you may want to
have `init_sort` use a custom sort before the
first render.)
Finally, we make the second and third calls
eliminate the prior updates from the previous
widget. This can prevent strange bugs with
double-reversing columns (although that's
been prevented in a better way with a recent
commit), as well as avoiding double work
with sorting.
This code has always been kind of convoluted
and buggy, starting with the first
sorting-related commit, which put filtering
before sorting for some reason:
3706e2c6ba
This should fix bugs like the fact that
changing filter text would not respect
reversed sorts.
Now the scheme is simple:
- external UI actions set `meta` values like
filter_value, reverse_mode, and
sorting_function, as needed, through
simple setters
- use `hard_redraw` to do a redraw and
trigger external actions
- all filtering/sorting/reverse logic on
the *data* happens in a single, simple
function called `filter_and_sort`
We don't use this anywhere. You can do
`git grep -A 40 list_render.create` to verify
this (with a little bit of noise in the grep).
A better strategy for generalizing
this code is to extract the useful logic
into a function that callers can use in their
own custom event handlers, which I'll do
in an upcoming commit.
We put this in `scroll_util` to make it more likely
we will eventually unify this with other scrolling
logic. (A big piece to move is ui.get_scroll_element,
but that's for another PR.)
And then the other tactical advantage is that we get
100% line coverage on it.
I changed the warning to an error, since I don't
think we ever expect scrolling at the `body` level,
and I don't bother with the preview node.
We extract a general purpose widget to create dropdown lists with
search. This widget is used for default code block language, but can
be easily extended to cover notifications_stream and similar options.
The current usage is:
```js
const widget = DropdownListWidget({
setting_name: 'realm_alpha_beta',
data: [{name: 'hello', value: 'world'}, {...}, ...],
subsection: 'msg-editing',
default_text: 'Nothing is selected',
});
```
and
```handlebars
{{> dropdown_list_widget
setting_name="realm_alpha_beta"
list_placeholder=(t 'Filter the data')
reset_button_text=(t '[Unset]')
label=admin_settings_label.realm_alpha_beta }}
```
This can further be refined by shifting more variables from handlebars
to javascript in the future.
By taking these functions out of exports.build_page, we can
reuse them for handling other widgets. We also declare
default_code_language_widget after the helper functions to
avoid the linter complaining.
I pushed this risk commit to the end of
a PR that had a bunch of harmless prep
commits at the front, and I didn't make
it clear enough that the last commit (this
one) hadn't been tested thoroughly.
For the list_render widget, we can simplify
the intialization pretty easily (avoid
extra sorts, for example), but the cache aspects
are still tricky on subsequent calls.
Changes .data() Jquery methods to .attr() to prevent unnecessary data
type conversions of the emoji name.
Tested the fix manually and verified the test-js-with-node test suite.

For some widgets we now avoid duplicate redraw
events from this old pattern:
widget = list_render.create(..., {
}).init();
widget.sort(...);
The above code was wasteful and possibly
flicker-y due to the fact that `init` and
`sort` both render.
Now we do this:
widget = list_render.create(..., {
init_sort: [...],

For other widgets we just clean up the need
to call `init()` right after `create()`.
We also allow widgets to pass in `sort_fields`
during initialization (since you may want to
have `init_sort` use a custom sort before the
first render.)
The get() logic here was broken, because
when you enter the settings panel for invites
on the 2nd or 3rd time, the text filter
would not work.
This commit doesn't intend to fix the problem; it
just simplifies the code for a later commit
that fixes this holistically.
The way that we update `list_render` objects
is janky with respect to events, so we can end
up double-sorting lists (which puts them back
to normal) and strange things like that.
This is all cosmetic.
Instead of:
const.widget = {
foo: function () = {
},
bar: function () {
},
};
We have:
const widget = {};
widget.foo = function () = {
};
widget.bar = function () {
};
Before this fix, we'd get a traceback if you looked
at invites in the settings (and if one of them was
a multi-user invite link). This commit fixes
that problem by adding a custom sort.
We also rename the "Email" column to "Invitee",
since it's often the case the invitee isn't an
actually an email, but it's instead a multi-use
link.
Note that the invites UI only works the first time you
enter settings. Many of the controls break the second
time you enter it. You can't sort by column header
or use the text filter.
I'll fix that in a subsequent commit.
Giving these functions a name and moving them to
the top-level scope has a couple tactical advantages:
- names show in tracebacks
- code is less indented
- setup code is less cluttered
- will be easier to add unit tests
- will make some upcoming diffs nicer
These are technically more `compare_foo` than `sort_foo`,
but we already had a naming convention that was sort of
in place.
We had a bug where if your peer mentioned you in
message, but then edited the message not to mention
you, the latter wouldn't reset your unread counts
for "Mentions". And the same problem would happen
vice versa.
The fix basically extracts `update_message_for_mention`
and makes sure it handles all combinations of
unread/mentioned flags, instead of assuming
any invariants about which directions of change
are possible.
And then we call that new function from
`message_events.js` whenever we get message
edit events.
Fixes#14544
Earlier, the non-editable text-boxes(on clicking view source/edit
topic) were not so apparent due to absence of `disabled` attribute.
Adding the `disabled` attribute makes them consistent with the approach
for non-editable text-boxes and text-areas in organization settings
(for non-admins).
Fixes: #14375
The `send_message_ajax` function was a relic
of us having an alternative way to send messages
(web sockets) to the server, but now the indirection
is more confusing than helpful.
This also fixes trying to cancel a resend of a
local message.
The problem were was type confusion between
strings and ints.
The function in `rows.js` may feel like overkill,
but I really want to enforce type safety here,
as we usually treat message ids as floats, but
for the local-echo case we're gonna get
strings. I put it in `rows` because we mostly
do a good job of encapsulating the "zid" role
in the DOM there.
By going directly to the DOM here, we avoid
parsing a string to a float and then converting
it right back to a string, which always make
me queasy about float rounding, so one less
moving part.
Due to type confusion, we were silently failing
to delete local_id values for messages that were
being acked by the server.
This used to work when we kept values in our
old Dict data structure, since client_message.id
and message.local_id are really the same value,
just the former is a float and the latter's a
string, and Dict never cared.
We can avoid all this confusion, though, by just
consistently using `local_id`, which I extract
to a local var.
The function message_send_error was messing up
on calls to message.get when we were passing in
string versions of `local_id`. Now we pass in
float ids.
This fixes a traceback where we tried to set
`.failed_request` on to an `undefined` value
that we had instead expected to be a locally
echoed message from our message store.
This will allow us access to the float version of the
message's id in an upcoming commit, without us having
to do possibly brittle string-to-float translations.
Option is added to video_chat_provider settings for disabling
video calls.
Video call icon is hidden in two cases-
1. video_chat_provider is set to disabled.
2. video_chat_provider is set to Jitsi and settings.JITSI_SERVER_URL
is none.
Relevant tests are added and modified.
Fixes#14483
This adds a new realm setting: default_code_block_language.
This PR also adds a new widget to specify a language, which
behaves somewhat differently from other widgets of the same
kind; instead of exposing methods to the whole module, we
just create a single IIFE that handles all the interactions
with the DOM for the widget.
We also move the code for remapping languages to format_code
function since we want to preserve the original language to
decide if we override it using default_code_clock_language.
Fixes#14404.
The filter-linkifier input box was disabled which prevented users from
filtering through the linkifiers list. Removed the part of code which
caused the input box to be disabled. This allows users to edit the input
and so filter linkifiers.
With EMAIL_ADDRESS_VISIBILITY_NOBODY (or as a non-admin with
EMAIL_ADDRESS_VISIBILITY_HIDDEN), we were incorrectly generating
zuliprc files containing the shareable email address, which naturally
didn't work.
Most failures result from invalid emoji names, so this makes it easier
to recover without re-uploading a file.
Previously, this model would have been problematic, but now that we
have the visual preview, this is clearly better behavior.
This adds a preview of the uploaded emoji image while uploading custom
emoji right below the upload form.
Modified upload_widget.build_widget() to take in the preview
span text and image. In case a parameter isn't passed
for preview text, it defaults to null and the snippets in
build_widgets() related to preview don't run.
Fixes#9229.
Styling tweaked by tabbott.
We now only compute idx on the outbound side,
instead of spreading out the responsibility.
We just iterate through all our items to find
the next available number.
The name here is a bit more precise, as we're
not checking whether a task exists so much
as whether just a particular name is in use.
We also move the function out of the `check_task`
layer, which feels a bit overkill in terms
of nesting (plus, we're gonna remove the other
function inside of `check_task` soon).
This is a prep commit for changes to the top navbar, it adds helpers
to filter.js which will help control the behavior of some aspects of
the redesigned navbar.
Modified by tabbott to add comments, internationalization tags on the
strings, support streams:public, and change various title strings.
This is a prep commit to the change of the navbar UI, in the new UI
the navbar and search box are toggled by icons and exist in the same
space on the UI. This commit only moves the search_box styles to be
near the tab_bar styles, so that future changes are easier to make,
read and maintain.
We fix this by adding a more expressive data function, with tests, for
whether a filter is on UserMessage data, which would mean that
streams:public could never add additional matches.
We now use `assert.throws()` to test that we're
properly calling `blueslip.fatal`.
In order to not break line coverage here, we have
to remove an unreachable `return` in `stream_data.js`.
Usually we test `fatal` for line coverage reasons.
Most places where we use `blueslip.fatal` fall in
these categories:
* the code is theoretically unreachable, but
we have `blueslip.fatal` for defensive reasons
* we have some upstream bug that we should just
fix
* the code should recover gracefully and just
use blueslip.errors()
It's possible that we should eliminate `blueslip.fatal`
from our API and just throw errors when really important
invariants get broken. This will make it more obvious
to somebody reading the code that we're not going to
continue after the call, and `blueslip` already knows
how to catch exceptions and report them.
The todo_widget was using the using a counter to store the key value of
every task. This would cause assiging multiple tasks the same key value
in a race condition. To avoid this we make "sender_id" a part of the key
along with the counter.
Also the `key` now not being a integer value, we can't use it to find the
index of the task using it. Thus, a function is made that will find the
index of task whose key is sent by the user to strike.
This is part of #6427, adding support for live-updating the Zulip UI
to move messages to a new topic.
As noted in the comments, there is still a bug to be fixed here
involving guest users, but the overall implementation is pretty well
tested manually (which is how we test most message-edit UI work since
there's so much complexity involved).

We no longer delete existing drafts if you happen
to clear the text in your compose box for a message
that was restored from an existing draft. This
prevents folks from losing drafts when they accidentally
delete selected text.
There are still two ways to delete a draft:
* send the message (obviously not always desirable)
* use the drafts UI (with `d` as a shortcut to bring it up)
See https://chat.zulip.org/#narrow/stream/9-issues/topic/lost.20draft

This commit modifies the padding and margin of the input selector so
that is uses sane values such as 25ps top margin, 5px bottom margin
and 10px top and bottom padding rather than trying to make uneven
values balance each other out. (old values are 25px top margin, 4px
bottom margin, 9px top padding, 11px bottom padding)
If the subscription data was changed from the left sidebar,
we previously would attempt to display the savings indicator
in the stream edit page which wasn't rendered yet. The bug was
introduced in commit 39577b58ba.
This approach is used to harden the codepath against bugs by
keeping the expectOne check in `settings_ui.do_settings_change`
function.

When we redraw the left sidebar, we need to tell the
topic list to clear its data structures (and do other
stuff like hiding its popover), since we are clearing
its parent container.
The commit f0e18b3b3e
introduced this regression in late January 2020.
That commit made topic_list use a vdom to avoid
unnecessary updates. Before that, topic_list did
a lot of brute-force redraws, which covered up the
fact that we weren't having stream_list telling it
when the rug was being pulled out from under it.
The boundary between stream_list and topic_list
has always been kind of complicated code, since
topic lists get embedded into the stream list.
The main interactions, though, are basically:
* topic_zoom.clear_topics() - you're leaving
a narrow that may or may not be zoomed
* topic_list.clear() - you're about to redraw
stream items in the unzoomed stream list
* topic_list.rebuild(stream_li, stream_id) -
you're building or updating a topic list
for the newly active stream

Users are unable to modify organization's profile picture, but

The `options` parameter is not being passed in any call
of `lightbox.open()` and it uses the same option i.e.
`lightbox_canvas` everytime which is now computed inside
`display_image()` directly.
`image` passed to lightbox.open() is already a jQuery object,
so we don't need to convert it explicitly. Also, the parameter
is renamed from `image` to `$image`.
Previously, lightbox.open() was responsible for retrieving
the image data from the DOM, saving it in `asset_map` and
finally displaying the image using that data. This
implementation wasn't correct for image list at bottom of
the lightbox because the `image` parameter passed to
lightbox.open() could contain more than one instances of
the image that had to be opened.
Now, the metadata of all the images in image-list is stored
in the `asset_map` while rendering the `image-list` inside
`render_lightbox_list_images()` and `lightbox.open()` only
looks for the metadata from `asset_map`.
Fixes#14152.
In case of video embeds, the previous logic used
`data-src-fullsize` or `src` as a key to look
for the metadata of video in `lightbox.open()`,
but while parsing, the key used while storing
the metadata was the video ID.
This doesn't make any sense because video's data
could never be accessed from `asset_map` and we
always needed to lookup the DOM for this.
This commit fixes this by using $img.attr('src')
as a key for `asset_map` for both, images and
videos. Since `src` is the link of preview image
in case of video embeds, it will always uniquely
determine the video ID and we won't loose
anything with the change in how videos handle
things.
Part of #14152.
The value of `canvas.parentNode` in `sizeCanvas()`
appears to be `null` sometimes and it throwed an
exception specially when you switch images from
the images-list quickly.
This changes the payload that is used
to populate `page_params` for the webapp,
as well as responses to the once-every-50-seconds
presence pings.
Now our dictionary of users only has these
two fields in the value:
- activity_timestamp
- idle_timestamp
Example data:
{
6: Object { idle_timestamp: 1585746028 },
7: Object { active_timestamp: 1585745774 },
8: Object { active_timestamp: 1585745578,
idle_timestamp: 1585745400}
}
We only send the slimmer type of payload
to clients that have set `slim_presence`
to True.
Note that this commit does not change the format
of the event data, which still looks like this:
{
website: {
client: 'website',
pushable: false,
status: 'active',
timestamp: 1585745225
}
}
Next to the checkbox of "Show previews of linked websites" added a
documentation link in order to help users not confuse its function.
To do this:
- Added the field 'help' which is the link for the documentation in
organization_settings_admin.hbs
- Added the if statement in settings_checkbox.hbs to check if the above
field exists.In case it exists, a help icon which leads to the documentation
link appears.
The specific field was added in order to be able to add a help link in
other settings as well.

Fixes the problem of recipient_bar_icons being too close to each
other. To improve spacing between them, classes are added, namely
recipient_bar_icon_link (for link icon) and reciepient_bar_icon
(for other icons). CSS for spacing these classes correctly, using
padding-left and padding-right, has been added zulip.scss
Manually tested for cases with single and multiple links present.
Fixes#14364.
When we tried to copy/paste multiple rows up to
and including the last row in our view, we'd have
a blueslip error when the `for` loop checked the
condition `rows.id(row) <= ...` after we had
called `row = rows.next_visible(row)` on the last
row. Basically, `rows.id()` would complain
about a non-existent row.
Now we extract that code into `visible_range`, so
that our `while` loop can exit as soon as we found
the last row in the range.
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

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

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.
