Continuing the efforts to reduce dom trashing from the previous
commits, here we remove the third forced reflow by reordering the call
to $(".top-messages-logo").show() via narrow.reset_ui_state(), such
that it happens before the other DOM writes in
recent_topics_ui.hide().
Tweaked by tabbott to avoid adding an unnecessary if/else statement
around recent_topics_ui.hide.
This is a prep commit towards pushing the reset_ui_state calls upwards
into recent_topics_ui, in order to prevent a forced reflow. One side
effect of this change is that we add a call to
`narrow_banner.hide_empty_narrow_message()` from `narrow.activate()`.
This likely has no visible effect, in that the message list rendering
process would end up setting the narrow_banner state correctly, but
logically it could in the future avoid a banner from a stale banner
incorrectly appearing before we've rendered the current view.
This is a prep commit towards extracting a reset_ui_state function
which we can call from here, narrow.activate(), recent_topics.show()
and recent_topics.hide().
We want that function because it will enables us to prevent a forced
reflow when navigating from recent_topics to stream: xyz.
Going through the description of commit
a150b9b0ae is highly recommended since
this is a related issue.
We had received a complaint on chat.zulip.org about navigation with
the keyboard `n` key being significantly slow (~5 seconds), the first
time `n` was pressed when starting from the recent topics view.
It was difficult to reproduce the amount of lag that was reported, but
running chrome with the profile tab set to 4x slowdown helped get
close to it.
Based on profiling from the original report, as well as locally with
chrome set to 4x slowdown, led to the realisation that recent topics
to stream navigation involved a lot of dom thrashing, and so this
series of commits aims to prevent this path from causing forced
reflows.
In this commit, we reorder the calls to $(...).show() in
recent_topics_ui.hide(), this prevents the first reflow in this path,
most likely because displaying message_feed_container before
message_view_header_underpadding was guaranteed to cause style
recalculations since the underpadding is visually above the message
container.
This causes a net 60 ms decrease in the first renarrow, an ~ 70 ms
increase in the second renarrow and an ~ 5 ms increase in the third
renarrow but, more importantly, it eliminates one reflow and sets on a
path where we can achieve strong gains in subsequent commits.
Migrates the `/update-subscription-settings` api endpoint to the
`ignored_parameters_unsupported` model, which is also currently used
by `/update-settings` and `update-realm-user-settings-defaults`.
This change is a step towards preparing for an eventual migration to
have all endpoints return an `ignored_parameters_unsupported` block.
Previously the `/update-subscription-settings` endpoint returned a
copy of the data object sent in the request.
Fixes#15307.
We show "Please enter your password" error inside the modal
if the "Old password" input is empty and "Please choose a new
password" error if the "New password" input is empty and do
not send a request to server.
Fixes#19901.
django-scim2 doesn't order the rows when fetching them in reponse to a
query using the filter syntax. We ensure that ORDER BY id is always
appended to the SQL queries.
We add the following tables to the user export:
AlertWord
CustomProfileFieldValue
RealmAuditLog
Service
UserActivity
UserActivityInterval
UserCount
UserGroup
UserHotspot
UserPresence
UserTopic
Except for UserCount, we achieve this by sharing
code with the realm export via
add_user_profile_child_configs.
UserCount is handled slightly differently than realm
exports due to which key we trigger off.
It's possible that RealmAuditLog is incomplete for
single users, since we may also want rows where they
are the acting_user. This commit finds rows where
they are the modified_user. For non-admins I believe
it's rarely the case that they are the actor, and
they will tend to be the modified user if the two
fields are different at all. For admins it's
arguable we want to see both changes they enacted
as well as changes that affected them.
This commit switches the BigBlueButton integration
to use SHA256 instead of SHA1 as BigBlueButton supports
it and scalelite does now, too.
Fixes#19966.
Previously, if an admin created a private stream with shared history
or a private stream with protected history, they would see the general
tab for that stream in the right side of the subscriptions_overlay as
expected, but, they would not see the pencil button to change stream
privacy unless they clicked a different stream and came back.
The reason for this has to do with how we receive events when we
create a sub. We first get an event with type "stream" and op
"create", we then get an event with type "subscription" and op "add"
ie we create the stream and then sub ourselves to it. Now, we render
`stream_settings.hbs` while handling the "stream create" event, at
this time we pass `can_change_stream_permissions` as false since
`(!sub.invite_only || sub.subscribed)` is false because we're not
subscribed yet. This causes us to skip the insertion of the
"change-stream-privacy" block which is a problem because when we're
handling the "subscription add" event, we run
`stream_ui_updates.update_change_stream_privacy_settings(sub)` which
tries to show the element via `.show()` but can't since the element
does not exist and as a result the admin user does not see the pencil
edit button.
This commit fixes the above bug by changing the template such that we
always insert the button, but conditionally apply
`style="display:none"`.
Fixes: #20345.
The main focus is on improving the instructions around claiming issues
to try to create less issue claiming spam.
Additionally, we haven't done a detailed update in a few years, and
some of the content is stale/irrelevant.
- Add missing link for GitHub.
- Fix broken links to Matt Ringel's blog post.
- Add link to Julia Evans blog post.
- Add section heading for "Questions Are Important."
- Rearrange some content to fit with new section heading.
With additional tweaks from tabbott:
* Avoid linking to chat.zulip.org not via our documentation.
* Avoid the CZO abbreviation.
I rewrote most of tools/lib/pretty-printer.py, which
was fairly easy due to being able to crib some
important details from the previous implementation.
The main motivation for the rewrite was that we weren't
handling else/elif blocks correctly, and it was difficult
to modify the previous code. The else/elif shortcomings
were somewhat historical in nature--the original parser
didn't recognize them (since they weren't in any Zulip
templates at the time), and then the pretty printer was
mostly able to hack around that due to the "nudge"
strategy. Eventually the nudge strategy became too
brittle.
The "nudge" strategy was that we would mostly trust
the existing templates, and we would just nudge over
some lines in cases of obviously faulty indentation.
Now we are bit more opinionated and rigorous, and
we basically set the indentation explicitly for any
line that is not in a code/script block. This leads
to this diff touching several templates for mostly
minor fix-ups.
We aren't completely opinionated, as we respect the
author's line wrapping decisions in many cases, and
we also allow authors not to indent blocks within
the template language's block constructs.
In cases where an opening tag is so long that we stretch
it to 2+ lines of code, we should try to use block-style
formatting in the template code.
Unfortunately, we have lots of legacy code that violates
this concept, so this is a timid fix.
There are also legit use cases like textarea where we
probably need to keep the ugly template syntax for things
to render properly.
We disallow this HTML:
junk-text-before-open-tag<p>
This is a paragraph.
</p>
We rarely see the above mistake, but we want to eliminate
the possibility to be somewhat rigorous, and so that we
can eliminate a pretty-printer mis-feature.
