It's natural that someone might try a wrong password 5 times, and then
go through a successful password reset; forcing such users to wait
half an hour before typing in the password they just changed the
account to seems unnecessarily punitive.
Clear the rate-limit upon successful password change.
We remove the StackOverflow link because it is now so dated as to be
irrelevant -- it does not use `self.ident`, and cargo-cults the return
value of PyThreadState_SetAsyncExc.
As noted in the docstring for this function, the timeout is
best-effort only -- if the thread is blocked in a syscall, it will not
service the exception until it returns. It can also choose to catch
and ignore the TimeoutExpired; in either case it will still be running
even after the `timeout()` function returns.
Raising a vare TimeoutExpired it still somewhat accurate, but obscures
that the backend thread may still be running along merrily. Notice
such cases, and log a warning about them.
Having just thrown an exception into the thread, it is often useful to
know _what_ was the slow code that we interrupted. Raising a bare
TimeoutExpired here obscures that information, as any `exc_info` will
end there.
Examine the thread for any exception information, and use that to
re-raise. This exception information is not guaranteed to exist -- if
the thread didn't respond to the exception in time, or caught it, for
instance.
The quote in question originates in python/cpython@b8b6d0c2c6, when
the code was added. However, the code stopped having that comment,
and was no longer able to return anything but 1 or 0, starting in
python/cpython@4643c2fda1 -- Python 2.5.
Remove the block.
This avoids an error when a user has already muted the new topic name.
We do this by ignoring duplicates, rather than catching the
IntegrityError, because this edit happens in a transaction, and that
would abort the transaction.
Our original implementation of moving muted topic records when a topic
is moved took a shortcut of treating all change_later usage as
something with intent to move the whole topic.
This works OK when moving the whole topic via this interface, but not
when moving a last off-topic message in the topic.
Address this by changing the rule to match the existing
moved_all_visible_messages variable.
Adds tab for web-public streams in documentation for setting
who can create new streams, as well as some text about why
this is limited to certain roles.
Removes list of actions that can be restricted to full members
due to maintainability concerns for that type of list in the
documentation and replaces it with a short descriptive text
explaining that many settings in Zulip support this restriction.
Previously, Attachment.is_realm_public and its cousin,
Attachment.is_web_public, were properties that began as False and
transitioned to True only when a message containing a link to the
attachment was sent to the appropriate class of stream, or such a link
was added as part of editing a message.
This pattern meant that neither field was updated in situations where
the access permissions for a message changed:
* Moving the message to a different stream.
* Changing the permissions for a stream containing links to the message.
This correctness issue has limited security impact, because uploaded
files are secured both by a random URL and by these access checks.
To fix this, we reformulate these fields as a cache, with code paths
that change the permissions affecting an attachment responsible for
setting these values to the `None` (uncached) state. We prefer setting
this `None` state over computing the correct permissions, because the
correct post-edit permissions are a function of all messages
containing the attachment, and we don't want to be responsible for
fetching all of those messages in the edit code paths.
When the credentials are provided by dint of being run on an EC2
instance with an assigned Role, we must be able to fetch the instance
metadata from IMDS -- which is precisely the type of internal-IP
request that Smokescreen denies.
While botocore supports a `proxies` argument to the `Config` object,
this is not actually respected when making the IMDS queries; only the
environment variables are read from. See
https://github.com/boto/botocore/issues/2644
As such, implement S3_SKIP_PROXY by monkey-patching the
`botocore.utils.should_bypass_proxies` function, to allow requests to
IMDS to be made without Smokescreen impeding them.
Fixes#20715.
`prepare_linkifier_pattern`, as of db934be064, adds a match to the
end of the regex, of either the end of string, or a non-word character
-- this is in place of a negative look-ahead, which is no longer
possible in re2. This causes the regex to consume trailing
whitespace, and thus not be able to match twice in succession with
`pattern.finditer` -- "#1234#5678" fails to match because the space
is consumed by the first match of the regex.
Rather than use `pattern.finditer`, write own own version, which
rewinds over the non-word character consumed after the match, if any.
This allows the same "after" non-word character to also satisfy the
"before" of the next match.
Fixes#21502.
Extends the linking to Zulip documentation to cover:
- Getting URLs to messages via the message timestamp.
- Getting links to topics via the three-dots menu.
- Getting links to streams via right-click context menu.
Creates a new tabbed section for using the browser
address bar to copy URLs.
Add support for moving MutedTopic entries to another stream where
the user has access to shared history in both streams and
`propagate_mode != "change_one"`.
Also, we delete them the current user does not have access to the
target stream.
We set nocoverage for the new function. Ideally it'd eventually get an
automated test, but we don't want to block this helpful refactoring on
doing so.
We now call this function inside do_create_user(...,
realm_creation=True), which generally improves readability and
robustness of the codebase.
This fixes a bug where this onboarding content was not correctly done
when creating a realm via LDAP, and also will be important as we add
new code paths that might let you create a realm.
This improves robustness of any code paths calling do_create_realm,
which previously needed to call this correctly to achieve the same
results as creating a user via the UI.
This also fixes a bug where this code was not called if a realm were
created using the LDAP code path.
This parameter was introduced in
ea11ce4ae6, and no longer serves a
purpose. Zulip will already correctly record that the user has not
agreed to ToS, and either prompt them on first login or not depending
whether the server is configured to require ToS.
Ordinary organization administrators shouldn't be allowed to change
ownership of a bot with the can_create_users permission.
This is a special permission that is granted manually by server
administrators to an organization (to a UserProfile of the org owners'
choice) after approval by a server administator. The code comments
provide more detail about why this is sensitive.
Previously, when a topic was edited (including being resolved), it
would become unmuted for any users who had muted it, which was
annoying.
While it's not possible to determine the user's intent completely,
this is clearly incorrect behavior in the `change_all` case, such as
resolving a topic.
The comments discuss some scenarios where we might want to enhance
this further, but this is the best we can do without large increases
in complexity.
Fixes#15210.

This commit adds the backend functionality to
mark messages as unread through update_message_flags
with `unread` flag and `remove` operation.
We also manage incoming events in the webapp.
Tweaked by tabbott to simplify the implementation and add an API
feature level update to the documentation.
This commit was originally drafted by showell, and showell
also finalized the changes. Many thanks to Suyash here for
the main work here, which was to get all the tests and
documentation work moving forward.
This commit creates a new TypedDict RealmPlaygroundDict for realm
playground objects. Now the list of playgrounds in the events sent
to clients and the "added_playground" field of RealmAuditLog entry
use RealmPlaygroundDict instead of Dict.
This commit modifies the notify_realm_playgrounds function to accept
realm_playgrounds as argument from the caller instead of computing it
in the function to avoid duplicate queries since the realm playgrounds
list will be required in its caller functions as well in further commits.
Clearing the sessions inside the transaction makes Zulip vulnerable to
a narrow window where the deleted session has not yet been committed,
but has been removed from the memcached cache. During this window, a
request with the session-id which has just been deleted can
successfully re-fill the memcached cache, as the in-database delete is
not yet committed, and thus not yet visible. After the delete
transaction commits, the cache will be left with a cached session,
which allows further site access until it expires (after
SESSION_COOKIE_AGE seconds), is ejected from the cache due to memory
pressure, or the server is upgraded.
Move the session deletion outside of the transaction.
Because the testsuite runs inside of a transaction, it is impossible
to test this is CI; the testsuite uses the non-caching
`django.contrib.sessions.backends.db` backend, regardless. The test
added in this commit thus does not fail before this commit; it is
merely a base expression that the session should be deleted somehow,
and does not exercise the assert added in the previous commit.
Adds documentation for admins to manage users via the user profile
modal for these actions:
- Deactivating a user
- Changing a user's role
- Changing a user's name
Creates two new tab sections because we still want to document
the ability to do these actions through the users section in
the organizational settings modal.
Also cleans up some text in the help center article for changing
a user's role.
Fixes#21318.
Fixes#21415.
