Every time we updated a UserProfile object, we were calling
delete_display_recipient_cache(), which churns the cache and
does an extra database hop to find subscriptions. This was
due to saying `updated_fields` instead of `update_fields`.
This made us prone to cache churn for fields like UserProfile.pointer
that are fairly volatile.
Now we use the helper function changed(). To prevent the
opposite problem, we use all the fields that could invalidate
the cache.
Clients fetching messages can now specify that they are able
to compute their avatar, and if they set client_gratavar to
True in the request (w/our normal encoding scheme), then the
backend will not compute it, and the payload will be smaller.
The fix starts with get_messages_backend. The flag gets
passed down through these functions:
* MessageDict.post_process_dicts.
* MessageDict.set_sender_avatar.
We also fix up the callers for post_process_dicts to explicitly
pass in the client_gravatar path, but for now they all just hard
code the value to False.
Message.get_raw_db_rows is moved to MessageDict, since its
implementation details are highly coupled to other methods
in MessageDict.
And then sew_messages_and_reactions comes along for the
ride.
We eventually want to move Reaction.get_raw_db_rows to there
as well.
We're about to have multiple post-processing stages for building
message dictionaries. Rather than having individual "hydration"
methods remove intermediate values, we just wait until the end.
This decouples the hyrdration steps. The potentional problem
here is that we may have a field like sender_is_mirror_dummy
that isn't part of the final payload, but we need it for
calculating display recipients and avatars. We don't want to
delete it too early from the objects.
This removes sender names from the message cache, since
they aren't guaranteed to be valid, and they're inexpensive
to add.
This commit will make the message cache entries smaller
by removing sender___full_name and sender__short_name
fields.
Then we add in the sender fields to the message payloads
by doing a query against the unique sender ids of the
messages we are processing.
This change leads to 2 extra database hops for most of
our message-related codepaths. The reason there are 2 hops
instead of 1 is that we basically re-calculate way too
much data to get a no-markdown dictionary.
Introduce MessageDict.post_process_dicts() will allow us
the ability to do the following:
* use less memory in the cache for repeated data
* prevent cache invalidation
* format data according to different client needs
The first use of this function is pretty inconsequential, but
it sets us up for more consequential changes.
In this commit we defer the MessageDict.hydrate_recipient_info
step until after we pull data out of the cache. This impacts
cache size as follows:
* streams - negligibly bigger
* PMs/huddles - slimmer due to not needing to repeat
sender data like email/full_name
Again, the main point of this change is to start setting up
the infrastructure to do post-processing.
This is a first step to eventually slimming the message cache,
but there are still some moving parts there to be worked through.
The more immediate benefit of extracting this function is that
we can put tests on it. Also, it isolates some functionality
that may go away as our clients gets smarter.
This commit prepares us to introduce a StreamLite class. For
these tests, we don't care about the actual contents of the
Stream, just the right stream is there.
Postgres doesn't like them, we don't have an obvious way to escape
them, and they tend to be sent by buggy tools where it'd be better for
the user to get an error.
This fixes a 500 we were getting occasionally.
The dictionary result for get_user_info_for_message_updates()
now has a `mention_user_ids` field that is a set of user ids
who were mentioned in a message.
Previously, the bot domain was calculated correctly in most
circumstances, but if you were using the root domain, it would be
e.g. ".chat.zulip.org", not "chat.zulip.org". We fix this, with
perhaps more use of setting REALMS_HAVE_SUBDOMAINS than would be ideal
if we weren't about to set that True unconditionally.
Usually a small minority of users are eligible to receive missed
message emails or mobile notifications.
We now filter users first before hitting UserPresence to find idle
users. We also simply check for the existence of recent activity
rather than borrowing the more complicated data structures that we
use for the buddy list.
This change is mostly based on a similar commit from hackerkid
in a feature branch. It borrows both code and ideas. Some of
it's my own stuff, as I was working on a newer branch.
We now call get_user_including_cross_realm_email() inside of
user_profiles_from_unvalidated_emails(), instead of using
get_user_profile_by_email.
This requires a few of our callers to pass down sender into us.
One consequence of this change is that we change the symptoms
for trying to send to emails outside of your realm. In some
cases, we simply raise an error that an email is invalid to us
instead of getting into the deeper validate_recipient_user_profiles
check.
This class simplifies the calling sequence to methods like
check_message and _internal_prep_message, and it's also more
type safe.
Checking for message types is encapsulated with calls to is_stream()
and is_private(). There are also shortcut constructors when you
know that the type of the address (stream vs. private), which is often.
In this we basically seed a single message for the user which will
be soft deactivated by sending a stream message / group PM to
ensure that is has at least one UserMessage row, since in real
world every human user will always have at least one User Message
row.
This function will help us in creating undisturbed experience for
returning soft deactivated users.
Tweaked by tabbott to fix minor performance and clarity issues.
In anticipation of have all unread message ids available to the
web app in page_params (via a separate effort), we are simplifying
the /topics endpoint to no longer return unread counts.
Instead we have a list of tiny dictionaries with these fields:
name - name of the topic
max_id - max message id for the topic (aka most recent)
The items in the list are order by most-recent-topic-first.
This new setting controls whether or not users are allowed to see the
edit history in a Zulip organization. It controls access through 2
key mechanisms:
* For long-ago edited messages, get_messages removes the edit history
content from messages it sends to clients.
* For newly edited messages, clients are responsible for checking the
setting and not saving the edit history data. Since the webapp was
the only client displaying it before this change, this just required
some changes in message_events.js.
Significantly modified by tabbott to fix some logic bugs and add a
test.
Rationale: For the more off-to-the-side edit history view, changes
are easier to digest by highlighting deleted content in red followed
immediately by added and changed content in green.
TODO: Toggle for showing the edited messages without highlighting;
deleted content would not be shown in this view.
This test fails on self.assertTrue(delay < 0.001 * num_ids, error_msg)
randomly. This commit adds debug code to see what the real values of
paramters are.
To get accurate count of the queries, we should make sure that
caches don't come into play. If we count queries while caches are
filled, we will get a lower count. Caches are not supposed to be
persistent, so our test can also fail if cache is invalidated
during the course of the unit test.
This commit solves the problem with Stream cache. This cache comes
into play when we use `get_stream` function. If cache is valid,
we will not issue queries to Stream and Recipient table. I think
the problem was one of those rare occasions when the Stream cache
got invalidated during the course of the test, due to which query
count was increased by 2. After this commit, we intentially invalidate
the Stream cache.
This makes it possible for Zulip administrators to delete messages.
This is primarily intended for use in deleting early test messages,
but it can solve other problems as well.
Later we'll want to play with the permissions model for this, but for
now, the goal is just to integrate the feature.
Note that it saves the deleted messages for some time using the same
approach as Zulip's message retention policy feature.
Fixes#135.
This fixes most cases where we were assigning a user to
the var email and then calling get_user_profile_by_email with
that var.
(This was fixed mostly with a script.)
The example_user() function is specifically designed for
AARON, hamlet, cordelia, and friends, and it allows a concise
way of using their built-in user profiles. Eventually, the
widespread use of example_user() should help us with refactorings
such as moving the tests users out of the "zulip.com" realm
and deprecating get_user_profile_by_email.
This fixes an issue with a nondeterministic number of database queries
being used in fetching bulk messages from the database. The source of
the problem was that we were fetching _all_ messages, not just the 600
that had been created by the test, and thus if the set of streams
present in messages in the test fixtures (which is random) changes,
the number of streams used (and thus number of queries) would change.
Change applies to both subdomains and non-subdomains case, though we use
just the EXTERNAL_HOST in the non-subdomains case if there is only 1 realm.
Fixes#3903.
This makes it super easy for frontend code using this view code to
produce a nice display of the history.
This also fixes an off-by-one error with the timestamps.
Based on work by Kartik Maji in #1204.
This has a few significant changes from the original version:
* We correctly handle filling in data for topic edits
* Has a complete test suite verifying correctness of the logic
* Currently, it doesn't include a special "start" entry
Things we may want to further change include:
* Adding a special "start" entry.
* Reversing the order of the history data returned for clarity.
