Anders Kaseorg 1f565a9f41 timezone: Use standard library datetime.timezone.utc consistently.
datetime.timezone is available in Python ≥ 3.2.  This also lets us
remove a pytz dependency from the PostgreSQL scripts.

users: Modify do_create_user and create_user to accept role.
We change do_create_user and create_user to accept
role as a parameter instead of 'is_realm_admin' and 'is_guest'.
These changes are done to minimize data conversions between
role and boolean fields.

Anders Kaseorg 840cf4b885 requirements: Drop direct dependency on mock.
mock is just a backport of the standard library’s unittest.mock now.

The SAMLAuthBackendTest change is needed because
MagicMock.call_args.args wasn’t introduced until Python
3.8 (https://bugs.python.org/issue21269).

The PROVISION_VERSION bump is skipped because mock is still an
indirect dev requirement via moto.

Anders Kaseorg fead14951c python: Convert assignment type annotations to Python 3.6 style.
This commit was split by tabbott; this piece covers the vast majority
of files in Zulip, but excludes scripts/, tools/, and puppet/ to help
ensure we at least show the right error messages for Xenial systems.

We can likely further refine the remaining pieces with some testing.

arpit551 f299f31340 analytics: Fix missing unique constraint when subgroup is null.
Replaced unique_together with UniqueConstraint in models that
covered nullable fields as in unique_together database indexes
don't work where subgroup=None. So added conditional unique
index handling invalid duplicate Count data.

Added 0015_clear_duplicate_counts migration to handle existing
data that violates the constraints.

Also corrected a test case in test_counts.py which didn't clear its
state properly and thus was accidentally taking advantage of this
database schema bug.

arpit551 b23a5431cd analytics: Add realm argument to analytics.
This changeset is prepartory work for doing something reasonable with
analytics data during the zulip -> zulip data import process (and
potentially e.g. slack -> Zulip as well).

To support that, we need to make it possible to do our analytics
calculations for a single realm.

We do this while maintaining backwards compatibility and avoiding
massive duplicated code by adding an optional `realm` argument to the
entrypoints to the analytics system, especially process_count_stat.

More work involving restructuring FillState will be required for this
to be actually usable for its intented purpose, but this commit is a
nice checkpoint along the way.

Tweaked by tabbott to adjust comments and disable InstallationCount
updates when a realm argument is specified.

Rishi Gupta 5e49da9285 analytics: Only update daily stats on day boundaries.
Previously we would update FillState for daily stats on hourly boundaries as
well. This would create two extra queries on the FillState table every hour
(for each CountStat), which adds roughly 50ms of extra processing for each
CountStat each day, as well as two extra lines each hour in the analytics
log. This can be a minor annoyance when backfilling stats.

Rishi Gupta 6dff22cbaf counts.py: Change check for LoggingCountStat to use isinstance.
I think this is more pythonic?

We could also get rid of LoggingCountStats altogether, since it's now just a

But I think it's nice to keep the distinction since they behave so differently.

2017-04-14 11:41:07 -07:00
Rishi Gupta 661de6bf25 counts.py: Remove filter_args argument from CountStat definition.
It turned out to not be that useful once we added subgroup. The previous
design of the CountStat object also assumed more reuseability of the *_query
strings than what ended up happening.

The filter_args also had some carrying costs:

* It's hard to be confident that filter_args other than the ones explicitly
  in our tests would have had expected behavior.
* The filter_args/join_args system is the most complex part of the CountStat
  object, and makes understanding the *_query strings unnecessarily
  difficult for a new contributor.

Rishi Gupta 9b661ca91f analytics: Replace CountStat.is_gauge with interval.
Groundwork for allowing stats like "Monthly Active Users".

CountStat.interval is no longer as clean a value as before, so removed it
from views.get_chart_data. It wasn't being used by the frontend anyway.

Removing interval from logger calls in counts.py is not a big loss since we
now include the frequency (which is typically also the interval) in
CountStat.property.

Rishi Gupta 20255e48a4 analytics: Change messages_sent_to_stream to a daily stat.
Analytics database tables are getting big, and so we're likely moving to a
model where ~all stats are day stats, and we keep hourly stats only for the
last N days.

Also changed the name because:
* messages_sent_* suggests the counts (summed over subgroup) should be the
  same as the other messages_sent stats, but they are different (these don't
  include PMs).
* messages_sent_by_stream:is_bot:day is longer than 32 characters, the max
  allowable length for a BaseCount.property.

Includes a database migration to remove the old stat from the analytics
tables.

Rishi Gupta 37bdc7c010 analytics: Remove COUNT_STATS['messages_sent:hour'].
Having both messages_sent:hour and messages_sent:is_bot:day is confusing,

Rishi Gupta 12d277d4f4 analytics: Change messages_sent:client stat to daily frequency.
A few reasons:
* Our two other subgroup'd message stats in UserCount are at CountStat.DAY
  frequency (messages_sent:is_bot and messages_sent:message_type).
* Keeping this stat at hourly frequency would likely double the size of our
  analytics table, given the current stats. (Counterpoint: if there are
  roughly as many active streams as active users, and we keep
  messages_sent_to_stream:is_bot at hourly frequency, then maybe this stat
  is only a 30% or 50% increase).
* We're currently only showing this on the frontend as a pie chart anyway.

It seems unlikely we will need count_message_by_stream without the

in the usual query form and replace count_message_by_stream with it.
This also has the benefit of shortening our list of "special case" queries
from two to one.

The pathways of the removed test will be covered more thoroughly in the new
TestCountStats tests.

Umair Khan 7d51efe9a1 Django 1.10: Fix dummy data for count stat.
Django 1.10 checks the foreign key constraints as part of the testing
suite so we need to create test data which passes validation tests.

umkay 5490442580 analytics: Replace all joins in raw SQL with natural joins.
We alter the behavior of our queries to no longer write rows with 0 counts
to the db, and pad with 0s in the related views code. As a result we are
also able to combine the where and join clause conditions in the sql
queries. This new behavior is also updated in our tests.

umkay 610e92b94e analytics: Add subgroup column to analytics tables.
This is a major change to the analytics schema, and is the first step in a
number of refactorings and performance improvements. For instance, it allows

* Grouping sets of similar CountStats in the *Count tables. For instance,
  active{_humans,_bots} will now have the same property, but have different
  subgroup values.

* Combining queries that differ only in their value on 1 filter clause, so
  that we make fewer passes through the zerver tables. For instance, instead
  of running a query for each of messages_sent_to_public_streams and
  messages_sent_to_private_streams, we can now run a single query with a
  group by on Stream.invite_only, and store the group by value in the
  subgroup column.

Rishi Gupta 82b814a1cd analytics: Simplify frequency and measurement interval options.
Change the CountStat object to take an is_gauge variable instead of a
smallest_interval variable. Previously, (smallest_interval, frequency)
could be any of (hour, hour), (hour, day), (hour, gauge), (day, hour),
(day, day), or (day, gauge).
The current change is equivalent to excluding (hour, day) and (day, hour)
from the list above.

This change, along with other recent changes, allows us to simplify how we
handle time intervals. This commit also removes the TimeInterval object.
