Steve Howell 6c90940f84 performance: Add UserMessageLite class.
This speeds up sending messages significantly.

For 1000 users, this speeds up create_user_messages from
0.652s to 0.0558s, so basically a 10x speedup.
2017-09-12 04:22:55 -07:00
Steve Howell 811fcf51ee Extract create_user_messages.
The logic to create UserMessage rows when you create a message
is very self-contained, and it's helpful to be able to profile it.
2017-09-12 04:22:55 -07:00
Steve Howell 7fbffb8e30 Optimize bulk inserts for UserMessage rows.
Avoiding ORM overhead makes inserting UserMessage rows
about 15 times faster.
2017-09-12 04:22:55 -07:00
Steve Howell d723be125a Optimize get_recipient_info() for sending messages.
This commit makes get_recipient_info() faster by never creating
Django ORM objects.  We use the ORM to create a values query
instead, and then we iterate over the rows to create various
collections of ids.

In order to avoid lots of code duplication, this commit unifies
how we query UserProfile for PMs and streams.  Prior to this
commit we were getting "wide" UserProfile objects out of
our memcached cache.  Now we just go to the database with our
list of userids.  The new approach at worst adds one hop to the
database for PMs, which aren't really a performance bottleneck
(compared to streams).  And the new approach actually saves a
hop when both partners aren't in cache (plus we don't pay the
penalty of hitting the cache itself).

The performance improvement here is easy to measure for messages
to streams with many users, even with all the other activity
that goes on inside do_send_messages().  I took test_performance()
in test_messages.py, set num_extra_users to 3000, and consistently
measured a ~20% speedup in do_send_messages().

This commit also eliminates fetching of emails.  We probably
could have done that in a prior commit, but in this commit it
is very explicit that we don't need it.  While removing email
from the query is a no-brainer, it actually had a negigible
impact on performance.  Almost all the savings here comes from
not create UserProfile objects.
2017-09-12 04:22:55 -07:00
Steve Howell d00c001b5f Create get_recipient_info().
This function returns a summary of recipient data for a message
that's being sent.  It's mostly just moving code into the
old function called get_recipient_user_profiles().
2017-09-12 04:22:55 -07:00
Steve Howell b562dedb53 Avoid using email to detect that the feedback bot is addressed.
This commit is necessary to prevent bringing back emails from the
DB for all N recipients of a message just to see if the feedback
bot is being invoked.
2017-09-12 04:22:55 -07:00
Steve Howell 6f0289ae79 do_send_messages(): Extract internal push_notify_user_ids set.
This is one more step toward not needing UserProfile objects.
2017-09-12 04:22:55 -07:00
Steve Howell 82b2bd8b65 Take user_ids in get_userids_for_missed_messages().
This helps us phase out the need for getting lots of UserProfile
objects.
2017-09-12 04:22:55 -07:00
Steve Howell 06c388774f do_send_messages(): Clean up service bot code.
We calculate `service_bot_tuples` earlier in the function, so that
we don't need "full" UserProfile objects later in the function.

This is part of consolidating code that basically just needs to
triage user_ids.
2017-09-12 04:22:55 -07:00
Steve Howell a22a22966f do_send_messages(): Create UserMessage objects with user_id.
This starts to phase out the need for UserProfile objects in
do_send_messages().  UserProfile objects are expensive to create
for large streams with lots of users.  The objects in the code
before this commit aren't even full UserProfile objects.

This change mostly sets up future performance improvements, but
we also get a minor speedup here when we run a test with 3000
stream subscribers.
2017-09-12 04:22:55 -07:00
Steve Howell ba397b5109 Use user_ids, not full objects, in render path.
There is no reason for either render_incoming_message() or
render_markdown() to require full UserProfile objects just to
triage alert words.

By only asking for user_ids, we save extra queries in two
callpaths and we make it easier to start using user_ids in
do_send_messages().
2017-09-12 04:22:55 -07:00
Steve Howell 9e8c24168d Extract get_typing_user_profiles().
This function is essentially a copy of get_recipient_user_profiles,
which is about to go away. The new function enforces the contract of
typing indicators, which is that they don't apply to streams, which
allows us to use a relatively simple approach for getting user
profile objects.

We are diverging this code, because the send-message path needs
more optimizations.
2017-09-12 04:22:55 -07:00
Steve Howell c87cc1447f Extract get_recipient_user_ids. 2017-09-12 04:22:55 -07:00
Steve Howell 56a552eec3 Get UserProfile objects directly for stream messages.
This change introduces an extra hop to the database, but it is
generally faster due to nuances of the DB and the ORM.  It
also sets us up to optimize get_recipient_user_profiles() by
avoiding creating ORM objects.

I measured the impact of this using a stream with 3000
subscribers, half of whom were idle, and it speeds things up
by 10%.
2017-09-12 04:22:55 -07:00
Steve Howell f5edeb01ae Calculate idle users more efficiently when sending messages.
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.
2017-09-07 06:59:44 -07:00
Steve Howell 97c5f085e7 minor: Extract locals in do_send_messages().
This is a prepartory commit for another refactoring.
2017-09-07 06:59:44 -07:00
Steve Howell 4ac6bc46c7 Add MutedTopic model.
This commit completely switches us over to using a
dedicated model called MutedTopic to track which topics
a user has muted.

This includes the necessary migrations to create the
table and populate it from legacy data in UserProfile.

A subsequent commit will actually remove the old field
in UserProfile.

Steve Howell 73c30774cb admins: Add private streams to never_subscribed.
Admins need to know about private streams to delete them, even
if they are not subscribed.  We send the minimal info possible
to the client to allow them to have a UI for that.
2017-08-27 19:08:04 -07:00
Tim Abbott 133f005530 markdown: Remove is_me_message UserMessage flags.
This never made sense to be a flag on the UserMessage table, since
it's not per-user state.  And in fact it doesn't need to be in a
database at all, since it's easily computed from content anyway.

Fixes #1099.

Steve Howell 87c4961597 Add zerver/lib/topic_mutes.py
This is mostly pure code extraction.

It also removes some dead code in update_muted_topic, where
were updating muted_topics spuriously before calling
do_update_muted_topic.
2017-08-24 14:20:35 -07:00
Tim Abbott d3e3c704d4 do_create_realm: Remove unnecessary second return value.

No change in behavior.
2017-08-22 14:26:17 -07:00
Steve Howell 81e3f489f2 Use sender realm in user_profiles_from_unvalidated_emails.
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.
2017-08-22 10:42:15 -07:00
Steve Howell 54edecd510 Replace adddressee.for_email() with for_user_profile().
This requires us to change not just the immediate caller, but
also some of their callers, to pass user_profile objects around
instead of emails.
2017-08-22 10:42:15 -07:00
Steve Howell c61c0f3edc Use user_profile, not email, in check_message().
We are trying to convert emails to user_profiles earlier in
the codepath.  This may cause subtle changes in which errors
appear, but it's probably generally good to report on bad
addressees sooner than later.
2017-08-22 10:42:15 -07:00
Steve Howell c56a631b65 Move user_profiles_from_unvalidated_emails -> addressee.py.
This will avoid circular dependencies.
2017-08-22 10:42:15 -07:00
Steve Howell 32f18f77d4 Extract two methods from recipient_for_emails.
We now have these methods:
    user_profiles_from_unvalidated_emails
    recipient_for_user_profiles
2017-08-22 10:42:15 -07:00
Steve Howell 30d37d1270 Add Addressee class.
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.

Tim Abbott fa4968da92 actions: Extract send_stream_creation_event. 2017-08-16 12:03:44 -07:00
Steve Howell 60cc8fd58a Extract do_mark_stream_messages_as_read.
This function optimizes marking streams and topics as read,
by using UserMessage.where_unread(), which uses a partial
index on the "read" flag.

This also simplifies the code path for ordinary message
flag updates.

In order to keep 100% line coverage, I simplified the
logging in update_message_flags, so now all requests
will show the "actually" format.

This is an interim step toward creating dedicated endpoints
for marking streams/topics as reads, so we do error checking
with asserts for flag/operation, so we don't introduce a
temporary translation string.

Tim Abbott 9081f2cf44 reactions: Store the emoji codepoint in the database.
This is the first part of a larger migration to convert Zulip's
reactions storage to something based on the codepoint, not the emoji
name that the user typed in, so that we don't need to worry about
changes in the names we're using breaking the emoji storage.

Tim Abbott dd49bec93c Fix changing email addresses back after email change.
We apparently were not correctly clearing the user_profile's email
address from caches when changing email addresses, which meant that
trying to look up the old email in the user_profile caches would still
work.

Fixes #6035.
2017-08-05 10:49:44 -07:00
Steve Howell 63f7b9a579 Remove "all" option for flag-updating endpoint.
The "all" option for 'message/flags' was dangerous, as it could
apply to any of our flags.  The only flag it made sense for, the
"read" flag, now has a dedicated endpoint.
2017-08-04 14:10:46 -07:00
Steve Howell 541156792e Add /mark_all_as_read endpoint.
This change simplifies how we mark all messages as read.  It also
speeds up the backend by taking advantage of our partial index
for unread messages.  We also use a new statsd indicator.

Jason Michalski 4f0110e081 Add unread_msgs to the initial state data.
We are adding a new list of unread message ids grouped by
conversation to the queue registration result. This will allow
clients to show accurate unread badges without needing to load an
unbound number of historic messages.

Jason started this commit, and then Steve Howell finished it.

We only identify conversations using stream_id/user_id info;
we may need a subsequent version that includes things like
stream names and user emails/names for API clients that don't
have data structures to map ids -> attributes.

Steve Howell 69fd967c5d topics history: Simplify data in /topics endpoint.
In anticipation of have all unread message ids available to the

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.

ScheduledJob was written for much more generality than it ended up being

Both the queue processor and ScheduledJob emails need to sometimes pass a

Durga Akhil Mundroy 146dfa6f0b org-permissions: Add allow_edit_history organiztion setting.
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.

Steve Howell 475eb21a5e Revert commits related to client_message_id.
I pushed a bunch of commits that attempted to introduce
the concept of `client_message_id` into our server, as
part of cleaning up our codepaths related to messages you
sent (both for the locally echoed case and for the host
case).

When we deployed this, we had some strange failures involving
double-echoed messages and issues advancing the pointer that appeared
related to #5779.  We didn't get to the bottom of exactly why the PR
caused havoc, but I decided there was a cleaner approach, anyway.
2017-07-14 12:13:35 -07:00
Steve Howell 8fbb55df85 Introduce client_message_id on the server.
We are deprecating local_id/local_message_id on the Python server.
Instead of the server knowing about the client's implementation of
local id, with the message id = 9999.01 scheme, we just send the
server an opaque id to send back to us.

This commit changes the name from local_id -> client_message_id,
but it doesn't change the actual values passed yet.

The goal for client_key in future commits will be to:
    * Have it for all messages, not just locally rendered messages
    * Not have it overlap with server-side message ids.

The history behind local_id having numbers like 9999.01 is that
they are actually interim message ids and the numerical value is
used for rendering the message list when we do client-side rendering.

We're getting rid of DEFAULT_FROM_EMAIL from prod_settings_template, since
we only really need one of {DEFAULT_FROM_EMAIL, ZULIP_ADMINISTRATOR}.

Tweaked by tabbott for more standard internationalization.

Rishi Gupta 1f77a0cdee confirmation: Remove Confirmation.objects.send_confirmation.
I think it makes sense to wrest the email sending from confirmation, now
that we have a clean email-sending interface in send_email. A few other
reasons:
* send_confirmation is get_link_for_object followed by send_email, but those
  two functions have no arguments in common.
* Sending email through confirmation obfuscates the context dict, and is a
  relatively complicated piece of the codebase anyone trying to deal with
  the email system has to understand.
* The three emails previously being sent through confirmation don't have
  that much in common, other than that they happen to have a confirmation
  link in them.

The .split('/')[-1] in registration.py is a hack, but a hack used several
places in the codebase, so maybe one day get_link_for_object will also
return the confirmation_key.

Steve Howell 549a1626d9 Optimize get_recipient_user_profiles().
For the fairly rare case that a user sends messages to themselves,
we now only call get_user_profile_by_id() once.

Rishi Gupta 056489c247 emails: Move verbose_support_offers into a common context.
Server settings should just be added to the context in build_email, so that
the individual email pathways (and later, the email testing framework)
doesn't have to worry about it.

Akhil 4986027126 org-settings: Add backend for notifications stream.
Realm.notifications_stream is not a boolean, Text or integer field, and
thus doesn't fit into the do_set_realm_property framework. Added function
to update it in actions.py. Altered the view, realm.py, to accept
stream-id. Also, notifications stream can be disabled by sending a
negative id.

Tim Abbott d2079cbb2e streams: Fix leaking private streams after last user is removed.
When the last user on a private stream is removed, the stream is no
longer possible to administer, and thus should be marked as
deactivated, so that default streams entries are removed and it no
longer appears in the UI as a non-administerable broken stream.

Tim Abbott d21756c396 streams: Fix default streams list not updating on deactivation.
If you deactivated a default stream, we would correctly remove it from
the list of default streams in the organization.  However, we did not
call `send_event`, so browsers would still display it as a default
stream until the next reload.

This fixes that issue by calling do_remove_default_stream instead of
doing the database query directly.

K.Kanakhin 2434f2d96c messages: Add support for admins deleting messages.
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.

Maxim Averin 685fb16c39 Switch change_full_name to use RealmAuditLog.
This requires adding an `acting_user` parameter to the
`do_change_bot_owner` function.
