As we add more features where rendered_markdown.update_elements does
something useful, it'll become important to run this code everywhere
we render markdown in the DOM.
One can see in this case that we had actually copied one hunk of
rendered_markdown.update_elements years ago, before we extracted it as
an independent function; we get to delete that copy.
Fixes#15500.
This particular commit has been a long time coming. For reference,
!avatar(email) was an undocumented syntax that simply rendered an
inline 50px avatar for a user in a message, essentially allowing
you to create a user pill like:
`!avatar(alice@example.com) Alice: hey!`
---
Reimplementation
If we decide to reimplement this or a similar feature in the future,
we could use something like `<avatar:userid>` syntax which is more
in line with creating links in markdown. Even then, it would not be
a good idea to add this instead of supporting inline images directly.
Since any usecases of such a syntax are in automation, we do not need
to make it userfriendly and something like the following is a better
implementation that doesn't need a custom syntax:
` Alice: hey!`
---
History
We initially added this syntax back in 2012 and it was 'deprecated'
from the get go. Here's what the original commit had to say about
the new syntax:
> We'll use this internally for the commit bot. We might eventually
> disable it for external users.
We eventually did start using this for our github integrations in 2013
but since then, those integrations have been neglected in favor of
our GitHub webhooks which do not use this syntax.
When we copied `!gravatar` to add the `!avatar` syntax, we also noted
that we want to deprecate the `!gravatar` syntax entirely - in 2013!
Since then, we haven't advertised either of these syntaxes anywhere
in our docs, and the only two places where this syntax remains is
our game bots that could easily do without these, and the git commit
integration that we have deprecated anyway.
We do not have any evidence of someone asking about this syntax on
chat.zulip.org when developing an integration and rightfully so- only
the people who work on Zulip (and specifically, markdown) are likely
to stumble upon it and try it out.
This is also the only peice of code due to which we had to look up
emails -> userid mapping in our backend markdown. By removing this,
we entirely remove the backend markdown's dependency on user emails
to render messages.

To make the typeahead code more readable, we extract this function to
timerender. We also improve the logic to be more readable, and add tests
to confirm its validity.
We have moved our invalid timestamp logic to use timestamp-error class,
however, if there are any valid outputs by the backend markdown that
the frontend considers invalid, we want to debug them. This commit
adds tooling to ensure we log those error messages.
We had been using !time() syntax for timestamps so far. Since its
an unreleased feature, we can make changes without affecting many
people.
Fixes#15442.
There is a bug and race issue that occurs when a message is selected
while we are in the process of reifying a locally echoed message,
raising the "Selected message id not in MessageList" error.
The code flow to get the exception is as follows:
* A user sends a message to the current narrow we are in.
* Before the new message event is received, we sent a message to
the same message list which renders it with a locally echoed id.
* One of the ways of getting the exception is to already have the
locally sent message selected, before receiving an acknowledgment
from the server.
* Thus the Message List Data's `selected_id` now points to the new
message id. The exception is raised on entering the `was_selected`
if block inside `message_list_view` which tries to re-select the
message.
Updating the `_rerender_message` code for this special case won't fix
the entire bug because, as mentioned above there are other ways of
getting the exception:
Ideally, after all our synchronous work (`echo.process_from_server`)
has completed we would expect the re-order and re-render work of the
`change_message_id` would occur first, due to the timer of the
setTimeout being set to 0.
However as evident from the race condition existing, this isn't always
the case. `change_message_id` function is responsible for 3 things:
updation, re-ordering and re-rendering.
The first one which is responsible for updating the message list's
local cache, occurs synchronously while for the latter two, they both
occur asynchronously.
Before the setTimeout which is responsible for the latter two actions,
is encountered the user might select the message by clicking or more
commonly by scrolling, which causes this message selection event to be
ahead of the setTimeout in the callback queue.
During this time frame, our race condition takes place.
And even though the message id is updated it's Message List is not
in the correct sort order, which leads to `closest_id` !== `id` in
`MessageList_select_id` being true and raising the exception.
Now, we only asynchronously call the re_render function, to guarantee
the data is always correct and UI updates should be done at the end.
Extended by tabbott to comment the setTimeout call.
Fixes#15346.
We change validate_stream_message to check the existence of stream from
the stream name in compose box early and we then pass stream_id or the
obtained sub objects accordingly to other validate functions.
Passing stream_id or sub objects to these functions, enables us to use
stream_id instead of stream name in stream_data.get_subscriber_count.
stream_data.get_stream_post_policy is also removed as we only used it in
validate_stream_message_policy, but we do not need it now as we can get
stream_post_policy directly from sub object obtained by early check of
valid stream name.
This commits add data-stream-id attribute to the compose_invite_users
template. This helps in avoiding the error that occured if user
clicked the link after renaming of stream.
As a result of above changes, the checks for empty and invalid stream
name in compose box are done in warn_if_mentioning_unsubscribed_user
function instead of needs_subscribe_warning function.
Escape all the possible special characters.
We replaced \b with (?:^|\s) since it matches word boundries including
special characters.
Pasted relevant stackoverflow links which expain them properly.
The organization_settings_tip is not visible if organization settings
overlay is opened with any section other than organization profile,
settings and permissions. This is because insert_tip_box is called from
settings_org.build_page, which is called only when we open any of the
above three sections after opening the overlay and not others.
We should call insert_tip_box function from admin.build_page instead
of settings_org.build_page because we need to insert the admin tips
each time the organization settings overlay is opened, irrespective
of the section which opens first.
The function insert_tip_box is moved to admin.js from settings_org.js,
because settings_org.js file handles the organization profile,
settings and permissions page only, while we display the tips in many
other sections including bots, custom emoji, etc.
Thus, it makes sense to move insert_tip_box function to admin.js, which
renders the complete organization settings overlay using render_admin_tab.
The flake was caused due to the fact that current_msg_list was not
populated with any messages in rare cases. We were missing a check
to guard against current message list having no messages. The
failure screenshot show no messages to prove this.
Relevant error:
Evaluation failed: TypeError: Cannot read property 'raw_content' of undefined
We leverage the composebox typeaheads to show flatpickr to pick dates
and times for the !time syntax.
We use moment.js to try and parse the time from current token. If we
are successful, we initialize flatpickr with the parsed time, else we
default to using the current time.
In 5200598a31, we introduced a new
client capability that can be used to avoid unreasonable network
bandwidth consumed sending avatar URLs of long term idle users in
organizations with 10,000s members.
This commit enables this feature and adds support for it to the web
client.
This commit changes stream_data.create_sub_from_server_data to use
stream id, instead of stream name, for checking whether subscription
already exists or not. We are using stream ids so that we can avoid
bugs related to live update after stream rename.
This commit changes stream_data.remove_subscriber to use stream id
instead of stream name. We are using stream ids so that we can
avoid bugs related to live update after stream rename.
Thsi commit changes stream_data.add_subscriber to use stream_id
instead of stream name. We are using stream ids so that we can
avoid bugs related to live update after stream rename.
This commit removes stream_edit.rerender function. We directly
call subs.rerender_subscriptions_settings directly from
server_events_dispatch.js, which was the only caller of rerender
function, as we already have sub object.
We are using stream ids so that we can avoid bugs related to live
update after stream rename.
We can use get_sub_by_id instead of get_sub to get the stream info,
as we already have stream id from the message object. We are using
stream ids so that we can avoid bugs related to live update after
stream rename.
This commit changes receives_notifications function to use
stream_ids instead of stream names. We are using stream ids so
that we can avoid bugs related to live update after stream rename.
Prior to this commit has:link, has:attachment, has:image
filter couldn't be applied locally and deferred filtering to
web server. This commits make sure client filters all messages
it can instead of completely deferring to the server and hence
improve speed.
A tradeoff is also made to turn off local echo for has: narrows
as messages with link sent to has:link narrow were locally echoing
to another narrow and not appearing in the active has:link narrow.
Fixes: #6186.
With this implementation of the feature of the automatic theme
detection, we make the following changes in the backend, frontend and
documentation.
This replaces the previous night_mode boolean with an enum, with the
default value being to use the prefers-color-scheme feature of the
operating system to determine which theme to use.
Fixes: #14451.

Add arrow key navigation support for recent topics.
Simple jquery is used to allow navigation for filter buttons,
a grid system is used for navigation inside table.
This improves the logic and fixes the bug where the href was calculated
based on the current URL and not the filter of the current message list.
We now add the '/streams/public/' operator at the start of the operators,
similar to how it is represented in all other cases.
Fixes#15405
This reverts part of b0d632577f.
The problem was that multiple queries were combined as a single
search pill. And since we create the pills then narrow / search,
we added a comma seperator between them for the typeahead lookups
as required by the logic in `input_pill.js`.
This however introduced a new bug where the search suggestions
were incorrect as the typeahead lookup table wasn't updated, so
every time an item from the type ahead was selected it updated
the input string with an invalid operator.
Thus to resolve the first problem, we follow a simpler approach
by extracting all operators from the search string using our
`Filter.parse` logic and next add the pills, one by one.
Whenever a search pill is selected or deleted by a click the navbar
gets rendered as the searchbox loses focus. This allows the user to
be able to continue editing the search query without having to refocus
the searchbox.
A main change is that we now display the navbar if the search box
is not focused. This was already present in the search pills version
but adding it to the legacy version is an improvement.
We sufficiently increase the timeout so that the pills are actually
deleted. This was required when `filter.is_common_narrow()` is true,
as then only we render the narrow description and close the search bar.
This commit also matches another behaviour of the legacy search.
i.e. We narrow every time a search suggestion is clicked.
The now redundant "focusin" and "focusout" event handler tests are
also removed.
Two things were broken here:
* we were using name(s) instead of id(s)
* we were always sending lists that only
had one element
Now we just send "stream_id" instead of "subscriptions".
If anything, we should start sending a list of users
instead of a list of streams. For example, see
the code below:
if peer_user_ids:
for new_user_id in new_user_ids:
event = dict(type="subscription", op="peer_add",
stream_id=stream.id,
user_id=new_user_id)
send_event(realm, event, peer_user_ids)
Note that this only affects the webapp, as mobile/ZT
don't use this.
This commit adds message retention policy details in the subscription_type
text below the stream description.
We do not show any text when realm-level settings is set to forever and
stream-level is set to either forever or realm_default.
This commit adds frontend support for setting and updating message
retention days of a stream from stream settings.
Message retention days can be changed from stream privacy modal of the
stream and can be set from stream_creation_form while creating streams.
Only admins can create streams with message_retention_days value other
than realm_default.
This commit also contains relevant changes to docs.
Previously, we had implemented:
<span class="timestamp" data-timestamp="unix time">Original text</span>
The new syntax is:
<time timestamp="ISO 8601 string">Original text</time>
<span class="timestamp-error">Invalid time format: Original text</span>
Since python and JS interpretations of the ISO format are very
slightly different, we force both of them to drop milliseconds
and use 'Z' instead of '+00:00' to represent that the string is
in UTC. The resultant strings look like: 2011-04-11T10:20:30Z.
Fixes#15431.
Since we are no longer using the "pointer" value sent in
page_params.pointer for anything, there's no value in continuing to
send it from the server to the client.
The remaining code in pointer.js is logic managing state for the
currently selected message.
