Tweaked by tabbott to move changes from the next commit that are
required for this to pass tests into this commit.
Note that this exports a few items that were not previously exported.
This change does a few things:
* I use "early return" to make the code a bit flatter
and easier to comment.
* I added more comments.
* I removed some unneeded passing of `invite_only` into
the template.
This uses the to-markdown.js library to do all the hard work of
parsing HTML and turning it into markdown and not e.g. uploaded files.
Tweaked by tabbott to better scope when it activates to just include
pastes of HTML content.
Fixes#5853.
The first part of this change is to have the "Your bots"
tooltip not lie about creating `.zuliprc`, because it
doesn't put a dot in front of the file.
And then the more significant change here is to make
the "Running a bot" documentation use realistic filepaths,
both in terms of where the download typically puts the file,
and where you want to move it to.
This commit helps reduce clutter on the navigation sidebar.
Creates new directories and moves relevant files into them.
Modifies index.rst, symlinks, and image paths accordingly.
This commit also enables expandable/collapsible navigation items,
renames files in docs/development and docs/production,
modifies /tools/test-documentation so that it overrides a theme setting,
Also updates links to other docs, file paths in the codebase that point
to developer documents, and files that should be excluded from lint tests.
Note that this commit does not update direct links to
zulip.readthedocs.io in the codebase; those will be resolved in an
upcoming follow-up commit (it'll be easier to verify all the links
once this is merged and ReadTheDocs is updated).
Fixes#5265.
Some of the calls in our codebase will call for the `.keys()` method a
lot, so this caches the results and returns them rather than mapping
the array if it knows the state to be the same as before.
If a user clicks on the pill container and not directly on a pill
or on an "x" inside of a pill, it should be presumed they are
trying to input new text. This effectively makes the whole non-pill
section an input bar.
This now allows all tab switcher components to be used with left
and right arrows, given that a tab is already in focus, which is
the default behavior unless overridden (like on the streams
overlay).
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.
This adds a slide class that specifies that the JS actions for sliding
up and down sections is the desired behavior, along with a bit of CSS
to help display correctly in the case of not being a sliding section.
Add a spinner for when a stream is being created to show that
an operation is being performed, while also disallowing users to
modify the form in the meanwhile.

Fixes: #5268.
This change prepares us to have the server send avatar_url
of None when somebody wants a gravatar avatar (as opposed
to a user-uploaded one).
Subsequent commits will change behavior on both the server
and client to have this happen. So this commit has no-op
code for now, but it will soon use the fallback-to-gravatar
logic.
The i18n.t function already escapes HTML, so we should avoid
calling jQuery's text() method, which double escapes the HTML.
The symptom reported here was that if you changed your
timezone to something like like America/Mexico_City, you'd
see `/` instead of `/`.
Most callers to the `ui_report` functions clearly call `i18n.t`
on the messages with code like this:
ui_report.success(i18n.t("No changes to save!"), status);
There are some exceptions:
blueslip.js: has really long hard coded messages
reload.js: mostly says "Reloading...", which perhaps we should
translate
settings_account.js: uses helper functions
settings_lab.js: uses local variable
settings_org.js: i18n happens in property_types
ui.js: uses generic_embed_error (unaffected by this change)
Fixes#7280
This commit is easy to revert if we want to tone down errors
to warnings for the short term, while our codepath still does
proper handling for adding users when they come in messages.
This logic used to be in extract_people_from_message(), but
we are deprecating extract_people_from_message(), whereas
the maybe_incr_recipient_count() function has logic that we
want to keep.
This change is the first step in making it so that we load
non-active users at page load time in the webapp.
Before this change, we would reactively handle deactivated
users when we saw them as senders in messages. Subsequent
changes will make it a warning if we see unknown senders
in messages.
There's no reason to include deactivated users in compose
typeahead, since we won't let the compose happen.
This also removes cross-realm bots from the typeahead, which
is mostly driven by not having a convenient function to include
them, but also it's rare that it makes sense to talk to a cross-realm
bot unless replying to it.
In addition to decreasing the excessive number of bundles we had, this
will set us up to fix rendering of code blocks when clicking the
sidebar links in the /api-new site.
This commit allows for the /api-new/ page to rendered similarly to our
/help pages. It's based on the old content for /api, but we're not
replacing the old content yet, to give a bit of time to restructure
things reasonably.
Tweaked by eeshangarg and tabbott.
The "subdomain" label is redundant, to the extent it's even
accurate -- this is really just the URL we want to display,
which may or may not involve a subdomain. Similarly "external".
The former `external_api_path_subdomain` was never a path -- it's a
host, followed by a path, which together form a scheme-relative URL.
I'm not quite convinced that value is actually the right thing in
2 of the 3 places we use it, but fixing that can start by giving an
accurate name to the thing we have.
We correct a bug on Firefox where using the ESC key to close an edit
box that was opened by the left arrow key caused the message feed to
lose focus, making it difficult to navigate the message feed by
keyboard afterwards.
We fix this bug by changing the function that handles the ESC key
during an edit to pass the correct object to the message_edit.end
function.
Fixes#7072.
Lets administrators view a list of open(unconfirmed) invitations and
resend or revoke a chosen invitation.
There are a few changes that we can expect for the future:
* It is currently possible to invite an email that you have already
invited, it might make sense to change this behavior.
* Resend currently sends an invite reminder instead of resending the
original invite, this is because 'custom_body' was not stored when
the first invite was sent.
Tweaked in various minor ways, primarily in the backend, by tabbott,
mostly for style consistency with the rest of the codebase.
Fixes: #1180.
This detects the meta key being pressed to open a page in a new
tab and therefore will prevent the page animation from fading out
the body content, in case the user wants to go back to that page
again.
We were incorrectly reporting active bots as non-active in
popovers, and we had no test coverage for cross-realm bots.
We also rename the function to is_active_user_for_popover,
since the old name, realm_user_is_active_human_or_bot, suggested
the wrong semantics for cross-realm bots.
Last but not least, we only do a blueslip warning if a user id
is not found. When lookups fail, we are pretty confident that
the user is not active, so an error is overkill. We can change
that as part of issue #7120.
Fixes#7153
It's easier to unit test logic inside of people.js than compose.js.
We allow users to compose emails to any of our cross-realm bots.
Someday we may tighten up which cross-realm bots are valid targets,
since it's not necessarily the case that those bots do anything
useful when you send them messages.
This dictionary includes bots, so the reference to
"people" in the name `realm_people_dict` was misleading.
We omit `realm` for brevity sake--it's usually the case
that folks implementing new features can safely ignore
cross-realm bots, and it's on our roadmap to move those
bots into the realm.
The function name `get_realm_human_user_ids` was a lie--it
includes active bots as well.
The only user of this function is `activity.js`, which wasn't
impacted by the misleading name, because we eventually filter
out bots in the `info_for` function.
It's possible that we actually want to include bots in the right
sidebar, since they can be difficult to discover in other parts
of the UI. Or, if we want to keep the right sidebar as all
human users, we may eventually want to make the logic to exclude
bots happen higher in the stack (but for real, this time).
This creates a dropdown in place of the normal register/login links
you get when logged out, with an option to go to the app or log out if
that appears you click on the avatar.
A bit more work is needed to make this look really good, but it's a
great start.
Apparently this is a bug that slipped in when we started showing
normal users as deactivated in the user popovers: all bot users were
treated that way as well.
We'll want to do #7153 as a follow-up to get things fully working how
we want them.
Previously, if you had the streams overlay open (but no active stream
clicked) while another user edited your subscriptions state, we'd
throw an exception handle the get_events call, because the code for
rerendering the subscribers list didn't consider the possibility that
there was no active stream.
The recent fixes we made to make stream settings update properly when
doing live updates were great, but they would throw an exception if
the stream settings overlay wasn't open. This fixes that by adding
the appropriate check.
We do not want the code to lead to a path where it will attempt to
display native notifications if the “Notification” object doesn’t
exist, as this likely means that the device does not support OS
notifications.
This shows the text "Never" for users who are part of a realm but
have never been active, rather than a more vague JavaScript output
of "Invalid Date" due to the fact that their last presence
evaluates to NaN.
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.
Notifications essentially don't work on any mobile web clients,
so don't even show the banner.
This also fixes a traceback where it checks the permission state
with `notifications.permission_state()`, which calls
`Notification.permission`, which will error due to `Notification`
not existing on mobile devices.
Fixes: #7105.
This reverts commit f04981513b.
We're not sure, but we suspect that this made Zulip not show es for
folks using es_es as their locale. Further testing is required.
This presents multiple states for the subdomain input option
depending on the existence of a root domain.
Commit modified heavily by Brock Whittaker <brock@zulipchat.com>.
Fixes#6863.
This removes a test for "webkit" in the userAgent string in order
to see whether notifications should be displayed. This is so that
the notifications process will work correctly in Firefox and not
keep registering as "false" which makes the notifications prompt
continue to re-show itself.
This checks whether the user is already in the state of having
blocked notifications, so that we can *not* show them the banner
to enable notifications, since browsers won't allow the request
to go through again.
Perhaps in a follow up we should create a different banner for
this case that shows how to enable notifications at the browser
level for this site.
This makes them responsive to resizes and fixes a responsive
issue with the floating recipient being too high when the alerts
were more than one line height.
This is a two-step notifications process that will ask a user
to enable notifications and if they click exit give them three
options:
1. Enable notifications.
2. Ask later.
3. Never ask on this computer again.
The first two are self-explanatory (ask later = next session it
asks again). The third is captured and stored in localStorage and
a check is done on page load to see whether or not notifications
should be displayed.
Commit modified heavily by Brock Whittaker <brock@zulipchat.com>.
Fixes#1189.
When re-subscribing by way of the "Subscribe" button in the right
side settings panel, the row will now be marked as active to
highlight that the row is still selected and being looked at.
Fixes: #6955.
We were getting several exceptions in mark_subscribed if the streams
overlay wasn't open, basically because we'd try to filter the
right-side stream list when it wasn't present in the DOM.
This adds back the perfectScrollbar for the sidebar and markdown
sections because we already lost CTRL-F functionality, so we may
as well bring back the pretty, non-obtrusive scrollbars.
This updates the scrollbar after a successful `slideToggle` of
one of the sidebar sections.
Fixes: #6999.
This changes the behaviour of the typeahead in the compose box to
start appearing with single letter lying in the range of a-z or '+'.
This is a nice solution, because all emoji names start with lower-case
letters, while most emoticons like :P use a capital letter or similar.
Fixes: #6808.
We had been waiting on doing this for a long time to make sure the
feature actually did what it was supposed to (completed last week);
this change adds the typeahead to ensure it actually works.
While we're fixing this, we remove the split between the edit and
compose code paths for typeahead, which is good, because we'd already
accidentally added the syntax-highlighting feature in only one place.
Fixes#195.
We never make an actionable distinction between the "unknown"
presence status and the "offline" status, so we now
just use "offline" as the status for persons who don't
have recent presence records that the client knows about.
(Usually, users without presence rows have never been online,
or they have been deactivated, or they have been offline so long
that they don't show up in our date-limited queries.)
We are about to stop supporting the presence status of "unknown."
Part of this fix is to stop checking for that status.
The implication of this change is that when we go
to display the time a user was last online, we now
mostly just look to see if presence.last_active_date
is undefined. We were wary of that approach before, but it
is probably the most sane approach here.
I updated the comment abover this section to reflect
our philosophy going forward.
BTW the timestamp is kind of buried in the UI for now, as you have to
open the popover and then hover over the circular presence
indicator.
We sometimes get blueslip errors from browsers that are clearly still
attempting to reload long after they should have. These browsers can
produce a lot of unnecessary presence update exceptions.
To solve that, we start checking reload_in_progress in the presence
code path.
While we're at it, we also add some blueslip logging for the reload
code path, in case it becomes useful when debugging future issues.
We've had a few reports of users using modern Chrome having problems
where reload.is_in_progress() was true, but the browser was just
sitting there, not having reloaded.
This will continually attempt to reload the page periodically try and
compensate for the behavior in Chrome where it appears that the tab
has to be active or semi-active for `location.reload` to be respected
when Chrome is trying to save power, which means that it should just
continually try until the page is active again, in which case the
`location.reload` func will work and reload the page.
See https://developers.google.com/web/updates/2017/03/background_tabs
for the Chrome featureset that we believe may be involved with this
issue.
Tweaked by tabbott to reload earlier and add the on-focus handler.
Fixes: #6821.
While applying formatting to drafts if any draft contains some syntax
which our markdown processor is unable to process delete the draft so
that drafts overlay can be opened without any error. Also report the
exception to the server so that error can be fixed.
The issue has a lot of extra details, but in short, if several
messages were sent at very close to the same time, it's possible that
the event queues will receive the "new message" events out-of-order.
This, in turn, could cause `get_events` to return an incorrectly
sorted block of messages. These would then be passed into
`message_list.add_messages`, which doesn't handle that sort of
unsorted situation correctly (in short, the `self.first.id()`
comparison checks are not accurate for that situation, since we don't
update the boundaries after the first messages is processed).
The end result of this bug was that it was possible for the message
list to be out-of-order, which in turn would cause exceptions when
scrolling with the mouse.
Fixes#6948.
Previously it was called before the event was processed by the server
and the subscription was updated to have the user subscribed to a
stream, so there was a race condition that would make it iso that
sometimes the stream line would disappear on the next render pass due
to the event not having completed yet.
This makes it so that the re-render happens after the event is
processed in `stream_events.js`.
Fixes: #6797.
This refactors the arguments in the `setup_subscriptions_stream_hash`
method to remove the `stream_id` param and just take it from the `sub`
argument it is passed (which is an object that contains the property,
`stream_id`.
This was a not-well-thought-through behavior change done in #6489; the
part that was actually a problem was ctrl-enter not producing spaces
anyway.
So we fix this, and also add a comment explaining why.
Fixes#6908.
Request for adding an reaction only if there is a default emoji or
an active realm emoji with that name while request for removing a
reaction should be sent only if there is a default emoji or a realm
emoji(may be active or deactivated) with that name. Earlier we were
not including deactivated realm emojis while deciding whether a
request for removing a reaction should be sent or not which was
causing requests for the removal of reactions with deactivated realm
emojis not to be sent to the backend.
Fixes: #6007.
The original "quality score" was invented purely for populating
our password-strength progress bar, and isn't expressed in terms
that are particularly meaningful. For configuration and the core
accept/reject logic, it's better to use units that are readily
understood. Switch to those.
I considered using "bits of entropy", defined loosely as the log
of this number, but both the zxcvbn paper and the linked CACM
article (which I recommend!) are written in terms of the number
of guesses. And reading (most of) those two papers made me
less happy about referring to "entropy" in our terminology.
I already knew that notion was a little fuzzy if looked at
too closely, and I gained a better appreciation of how it's
contributed to confusion in discussing password policies and
to adoption of perverse policies that favor "Password1!" over
"derived unusual ravioli raft". So, "guesses" it is.
And although the log is handy for some analysis purposes
(certainly for a graph like those in the zxcvbn paper), it adds
a layer of abstraction, and I think makes it harder to think
clearly about attacks, especially in the online setting. So
just use the actual number, and if someone wants to set a
gigantic value, they will have the pleasure of seeing just
how many digits are involved.
(Thanks to @YJDave for a prototype that the code changes in this
commit are based on.)
We now return user_ids for subscribers to streams in add-stream
events. This allows us to eliminate the UserLite class for
both bulk adds and bulk removes. It also simplifies some JS
code that already wanted to use user_ids, not emails.
Fixes#6898
This function was extracted from build_user_sidebar(). We
also slightly streamlined it to not unnecessarily call
filter() when the filter text was blank. This extraction
also eliminated the need for us to have the two-line
filter_and_sort() function.
Also, we get to 100% coverage in this commit.
We now intialize user-list-filter within activity.initialize(),
which gives us more control to set the module variable
`meta.$user_list_filter` before we build the user sidebar,
while setting up its handlers after we build the sidebar.
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.
Previously we used to mark a key as unstranlated if its value was equal
to it in translations.json. This had an issue because it didn't allow
otherwise valid cases where key was equal to the value.
This commit solves the problem by disallowing an empty string as a valid
translation and then using the empty string as the value for all the
unstranslated keys.
Fixes#5261
Currently when hovering on an emoji it will focus it, which makes
the browser by default scroll down or up to include the entirity
of the focused element. This corects the scrollTop to what it was
before the focus event adjusted the scroll position.
This is a follow-up to #6869.
Previously, you had to hover over the smaller area where the emoji
image was to select it, whereas the user expectation is that hovering
the emoji's padding should select it as well.
This commit makes the arrow key navigation and mouse hover affect the
same state such that for example if one moves the mouse over some emoji
and then hits down-arrow the cursor will move down by one from where he
left the mouse at rather than beginning from the top-left corner.
Fixes: #6827.
This will look through all users and not just ones active in the last
three weeks but only when you are searching with the right sidebar
input box.
Fixes: #5775.
This tries to toggle the next item when clicking on an <h2>
in the sidebar, however we want to first check the next item is
an <ul> element, so that we are collapsing or showing a list,
instead of something like an <h2> which currently happens with
the "#guides" element.
The `have_scrolled_away_from_top` logic goes way back
to November 2012.
Now we unconditionally load older messages when we scroll
to the top of the feed. Before this bug, you could get
"stuck." It was a bit difficult to reproduce, but with
the right combination of render window sizes and batch
sizes, you would hit the home key quickly and hit the top
of the feed in a way that the flag got in the way of
going back in history.
Fixes#6628
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.
Before this, the home key would go to the first message in our
render window. Now we go to the first message in our local
list of messages. (Note that there may still be older
messages, so it will still often take multiple uses of the
home key to truly get to the top of your feed.)
In the refactoring in 31d3b1ecc0 that
fixed live-updating of the medium-size avatar data, we started just
fetching the normal-size avatar, not the medium-size avatar. We fix
this by changing this code path to pass in the user object and
construct the URL using that.
While we're at it, we switch to using the user ID, not the email, to
construct these avatar URLs.
Previously, we relied on fetching the name of the user from the data
attributes on the individual elements, when we can get a more reliably
up-to-date value from the people.js data structure we're fetching
anyway.
"Mobile push notifications always" is now indented and a
sub-setting of "Mobile push notifications when offline".
It can be selected only when the outer setting is
selected, otherwise it is greyed out.
Fixes#6570.
We've iterated on this code incorrectly something like 3 times now, so
it's worth rewriting it with a lot of comments in a way that makes
sense.
The main actual functional change here is that modified key + enter
now is consistently the opposite of enter (in terms of whether to
provide a newline or send the message) in all cases.
Fixes#6489.
Emoji showcase refers to the space at the bottom of the emoji
picker we use for showing name as well as aliases of the currently
focused emoji.
Fixes: #6110.
This hack was used to fix the broken flag emojis in emoji-picker.
It was broken due to the incomplete migration to iamcal dataset.
See issue #4775 for more details.
This commit switches to use sprite sheets for rendering emojis
in all the remaining places, i.e., message bodies and composebox
typeahead. This commit also includes some changes to notifications.py
file so that the spans used for rendering emojis can be converted
to corresponding image tags so that we don't break the emoji rendering
in missed message emails since we can't use sprite sheets there.
As part of switching the bugdown system to use sprite sheets, we need
to switch the name_to_codepoint mappings to match the new sprite
sheets. This has the side effect of fixing a bunch of emoji like
numbers and flag emoji in the emoji pickers.
Fixes: #3895.
Fixes: #3972.
The sidebar selectors may not exist at a particular point on load but
we’d like to realistically cache the results once they are, so we try
to load them live until we know that a valid selector has been found.
This call to update the users scrollbar is inside a huddles update
method which should only affect the group PMs, so we can remove the
update function.
The `exports.build_user_sidebar` method already calls the resize
function, so there’s no need to call it again or wrap it in the
`actually_update_users_for_search` method.
When a `data-sort` is clicked in the body, it will trigger an attempt
to find the closest `list_render` instance, retrieve it from memory,
and then sort by the particular method specified.
This allows for someone to specify a generic sorting function which
accepts a prop to sort by, a sorting function which runs with just a
function on the whole object, and the ability to remove the sorting
function in play.
This adds the perfectScrollbar to the uploads table so that it will
function properly in the settings container since the parent node has a
perfectScrollbar.
This adds the perfectScrollbar to the right side and theoretically
updates it any time a piece of code interacts with the sidebar and
updates the counts of users displayed in it.
This shows the download instructions only selectively based on
whether the device has download instructions for it. This means
currently it shows the page for Windows, Mac, and Linux.
The list needs to be set to use perfectScrollbar so that it can
scroll due to the fact that it resides within another instance of
perfectScrollbar.
Fixes: #6351.
This combines two different selections of the
`#stream-filters-container` into one chained selection and writes a
comment on how it is possible due to the return value of `.css`.
This adds a centered layout for mobile and responsive screens where the
emoji picker is guaranteed to be in the center of the screen, and the
rest of the screen darkens behind it.
Fixes: #6291.
We want to scroll the left sidebar to the top as soon as the user
zooms in on a stream, and we don't want to wait for the server,
otherwise we'll get jumpiness.
This commit is a bit complicated, because we do full redraws of
the topic list frequently, and we don't want to randomly obliterate
our "No more topics found" message, so we need to keep a bit of
extra state around.
We now use a template to render the "more topics" link.
We also remove an unnecessary conditional and an unnecessary
attribute.
Finally, our unit tests are a bit more granular now.
This will make testing a bit easier (we can stub stuff before
building the widget), and it will eventually give us more control
on redrawing the topic list.
We were parameterizing max_topics, but it made the calling sequences
unnecessarily complicated. We don't ever override the value, not
even in tests, so now we just set in build_list().
This puts build_list on the widget object, which will make it a
bit easier to unit test, and it's more consistent with the rest of
the function. This also reduces the scope of the `my_stream_name`
variable and moves the initialization of `self.topic_items` into
build_list.
If a user re-narrows to another stream before our server gives
us more topic history, or they zoom out, we can avoid drawing
the topic list. Note that our data structures will still be
updated, although the only time that really matters is for
the corner case of a low-traffic stream. For a low traffic
stream that only had 3 or 4 topics in the original message
fetch, but has longer history, the next time you open the
stream in the sidebar, even when you're zoomed out, you will
see more topics.
Despite a few warts, we are going forward with getting topic
history from the server when you click "more topics." This
commit simplifies the code by removing the feature flag
checks.
Our old optimizations to prevent re-rendering of locally echoed
messages created a lot of code complexity. This commit is an
experiment to simplify the code, which it clearly does. The
danger of re-rendering messages is flicker, but our message
view has changed since the original local echo code was written.
It's kind of confusing to have a filter function that has massive
side effects. Now we just have a simple loop where we triage
some messages into non_echo_messages and do an early-exit in the
loop function. This change also introduces the more explicit
variable name of `non_echo_messages`; before we were shadowing
`messages`.
We need a migration to clear the tutorial_status for existing users,
so that we don't show hotspots to anyone who signed up for Zulip in
the month or so since we deleted the old tutorial.
On a standard keyboard, 'q' is to the left of 'w', so it makes sense
for the hotkeys for the left and right sidebars to be `q` and `w`,
