Zulip attempts to validate that the regular expressions that admins
enter for linkifiers are well-formatted, and only contain a specific
subset of regex grammar. The process of checking these
properties (via a regex!) can cause denial-of-service via
backtracking.
Furthermore, this validation itself does not prevent the creation of
linkifiers which themselves cause denial-of-service when they are
executed. As the validator accepts literally anything inside of a
`(?P<word>...)` block, any quadratic backtracking expression can be
hidden therein.
Switch user-provided linkifier patterns to be matched in the Markdown
processor by the `re2` library, which is guaranteed constant-time.
This somewhat limits the possible features of the regular
expression (notably, look-head and -behind, and back-references);
however, these features had never been advertised as working in the
context of linkifiers.
A migration removes any existing linkifiers which would not function
under re2, after printing them for posterity during the upgrade; they
are unlikely to be common, and are impossible to fix automatically.
The denial-of-service in the linkifier validator was discovered by
@erik-krogh and @yoff, as GHSL-2021-118.
Also added a waitFor for the modal to disappear and removed
waitFor for the spinner to hide which would obviously be hidden
with modal and it also doesn't add much value.
Users wanted a feature where they could specify
which users can create public streams and which users can
create private streams.
This splits stream creation code into two parts,
public and private stream creation.
Fixes#17009.
We will add realm-level defaults of notification settings in
further commits which will result in two elements with same
class. So, this commit specifies container element id along
with the class of setting element to make sure that we wait
for the correct element.
This test was `assert`ing the draft is not getting cleared
as soon as sending, which is desired behaviour to some extent
because we don't want to delete it until we receive a confirmation
from the server, but given the right amount of delay (or very
low network latency), the draft will be cleared. This inconsistency
was causing failures.
We could better test this with a node test. A node test was
already added in #18827.
Before this commit, the message or any draft is deleted as soon
as the compose box is closed. So, it removes that by removing
delete_active_drafts and instead this commit will add the deletion
process of drafts in reify_message_id that is called when a
message is successfully sent and received.
Now, see there are two types of messages, one that are locally
echoed and the second ones are that aren't locally echoed but
sent directly to server. This commit only saves the message in
draft if it is locally echoed as they are the only messages
that show message failed in message list. The non locally echoed
ones aren't remove from the compose box until they are
successfully sent. Now as the draft-id is stored in the message
data for locally echoed messages, as they are echoed from the
server, they are deleted using that draft-id.
This also adds node tests for echo reify_message_id for testing
this feature that this commit is adding.
Fixes#17697
We rename class of notification settings except checkboxes
by prefixing them with 'setting_' for clarity.
We do not change class of checkboxes because settings_checkbox
is used by other templates also and if we only change class
of those using notification_settings_checkboxes then live
update code will break and will need to add separate condition
for differentiating between which partial template is used.
This is a prep commit for adding UI for realm-level default
of user settings. We refactor the code to use classes
instead of ids such that we can use the common code for the
new settings.
We add a prefix to id of default_language_modal.hbs
such that we can use the same code for user settings
and realm-level settings.
We also add a class "default_language_modal" to the
modal div to avoid duplicate css.

As the right sidebar re-renders many times, often the
element puppeteer selected becomes stale, to avoid this
issue we are using javascript to click on the element.
This commit also ensures that the set user status modal
is completely open before we start clicking.
This commit improves the approach to click on the menu
icon on the right sidebar. It'd first hover on the list
instead of the menu to avoid the occasional "HTML node
not present" error. As menu icon our only visible when
we hover over the item.
We rely on calling eventually_render_bots from the event handling
code path for bot events to both updating the list and switching
the tab.
Now we decouple the logic and make render_bots take care of
rendering the list of bots only and switch the tab upon calling
the success handler of creating the bot.
Fixes: zulip#17743
This commit changes the edit-linkifier modal to use
dialog_widget instead of edit_fields_modal.
The edit_fields_modal module will be removed in
further commits to avoid code duplication.
This commit renames the variables, functions used in confirm_dialog.js
and classes and ids used in confirm_dialog.hbs.
This change is made so that we can easily migrate edit_fields_modal to
use this same code with some more changes.
We will change the file names and correspondingly import variables in
the next commit.
Since do_create_realm also creates general and core team streams,
we rename general to verona right after the realm is created. Mostly
because we dont really want two additional streams and this might
probably make it easy to review things.
There are puppeteer test changes because, we have a new "core team"
stream in tests as well as there is a new default notification stream
"Verona". Because of this tests in message-basics for example have
to be changed since the newly added core team affects the order in
which we navigate through the streams using arrow keys.
The extra await for selector was added in subscriptions test to make
the tests wait. Without the await the tests were passing ocassionally
and failing in some other times.
Fixes#6967
This commit renames confirm_dialog_yes_button class to
confirm_dialog_submit_button. This will help in keeping
a general class name when deduplicating the code for
confirm_dialog and edit_fields_modal.
The current system to change stream information like Stream name and
description isn't consistent with what we use everywhere else. It's
also slightly difficult to maintain.

We separate "Your account" section to two different sections -
"Profile" section for user name, custom profile fields, and avatar
and "Account & Security" section for email, password, role, api-key
and deactivating button.
Another important change here is that the modal for changing name
is removed and now the name has a simple input text box and it
behaves similar to inputs for custom-profile-fields.
Fixes#18848.
This commit modifies the linkifier-edit modal to use newly added
edit_fields_modal framework.
One important change is that we remove the "edit-linkifier-status"
element as the corresponding "edit-fields-modal-status" element
is added in edit_fields_modal.hbs and we also modify the css
accordingly. This "edit-fields-modal-status" is used only for
this modal and remains empty for others, so this change does not
cause problems with other modals.
There is another element which uses "edit-linkifier-status" as a
class, but the css we defined was for "edit-linkifier-status" as
id, so the css change is also safe.
We show a spinner inside the button instead of hiding the button
and then showing the spinner in the bottom area. We also disable
the button to avoid repetitive clicking by user.
We now validate the linkifier urls and patterns together, and add
the following additional checks:
1. All groups in the pattern must be used in the URL format string.
2. All groups in the URL format string must be declared in the pattern.
Linkifier pattern is now validated inside the `clean` method.
`filter_pattern_validator` is moved from `clean_fields` to `clean`
method as a safe check. As a result of this, a Puppeteer test case
is updated.
NOTE: The changes here are IN ADDITION to the existing validations.
Fixes#16482.

In this 90041ff453,
we remove the `info` class from the message action
menu, that's why it was failing.
This commit replaces it with the correct selector.
This commit fixes a rare flake where it accidentally clicks
on "Subscribe to more streams" instead of "Verona"
(stream). This happens because `#stream_filters` list
was not completely updated, i.e. It still had "Venice" and
"Verona" on the list, when it searched for "ver".
When it decided to click on the "Verona", "Venice"
disappeared, which causes "Verona" to move up and
causing "Subscribe to more streams" to click.
On slower systems it may take more than 4 seconds for the
stataus message to dissapear from the DOM, so it's better
to wait for the default duration of 30 seconds before
proceeding.
Thanks to @Riken-Shah for suggesting the fix.
I'm not sure that settings UI is particularly worth having puppeteer
tests for, so it's possible we shouldn't bring these back at all. But
in any case, it's worth disabling them as they've been failing for
some time.
This commit solves a rare flake, where the `realm
_linkifier.ts` test was failing because there was no
appropriate wait call for the table
(`#admin_linkifiers_table`) to get updated after editing
the pattern.
