Most of the code in show_unreads is for diagnosising unread
counts issues, and we may not use that often.
We're creating a dedicated fix_unreads management command with
less clutter.
This causes `upgrade-zulip-from-git`, as well as a no-option run of
`tools/build-release-tarball`, to produce a Zulip install running
Python 3, rather than Python 2. In particular this means that the
virtualenv we create, in which all application code runs, is Python 3.
One shebang line, on `zulip-ec2-configure-interfaces`, explicitly
keeps Python 2, and at least one external ops script, `wal-e`, also
still runs on Python 2. See discussion on the respective previous
commits that made those explicit. There may also be some other
third-party scripts we use, outside of this source tree and running
outside our virtualenv, that still run on Python 2.
This management command creates the same indexes as migrations
82, 83, and 95, which are all indexes on the huge UserMessage
table. (*)
This command quickly no-ops with clear messaging when the
indexes already exist, so it's idempotent in that regard. (If
somebody somehow creates an index by the same name incorrectly,
they can always drop it in dbshell and re-run this command.)
If any of the migrations have not been run, which we detect simply
by the existence of the indexes, then we create them using a
`CREATE INDEX CONCURRENTLY` command. This functionality in
postgres allows you to create indexes against large tables
without disrupting queries against those tables. The tradeoff
here is that creating indexes concurrently takes significantly
longer than doing them non-concurrently.
Since most tables are small, we typically just use regular
Django migrations and run them during a brief interval while
the app is down.
For indexes on big tables, we will want to run this command
as part of the upgrade process, and we will want to run
it while the app is still up, otherwise it's pointless.
All the code in create_indexes() is literally copy/pasted
from the relevant migrations, and that scheme should work
going forward. (It uses a different implementation of
create_index_if_not_exist than the migrations use, but the
code is identical lexically in the function.)
If we ever do major restructuring of our large tables, such
as UserMessage, and we end up droppping some of these indexes,
then we will need to make this command migrations-aware. For
now it's safe to assume that indexes are generally additive in
nature, and the sooner we create them during the upgrade process,
the better.
(*) UserMessage is huge for large installations, of course.
This no longer does the correct thing (in terms of onboarding emails,
default streams, etc), and is tempting for new server admins to use.
Once we remove it we'll also have the invariant that we can't have a realm
without a user, which will simplify accounts_register a bit.
This now breaks the process of cleaning up unread counts for
non-active streams into a three step process.
This allows us to use our unread message flags index, at least
in testing on dev. Here is the relevant excerpt from explain
analyze:
Bitmap Index Scan on zerver_usermessage_unread_message_id
This makes supervisor see the service as cheerfully running
and let it alone, rather than constantly retry starting it.
Because the crash/restart loop means repeatedly spending a
couple of seconds loading Django and the app, separated by
brief periods while supervisor notices the crash and acts
on it, it was actually consuming about 30-50% CPU on the
zulipchat.com staging server.
This is to be used for the case of container orchestration instead of
shell arg to prevent snooping by any user account on the server via `ps
-ef` or any superuser with read access to the user\'s bash history.
ScheduledJob was written for much more generality than it ended up being
used for. Currently it is used by send_future_email, and nothing
else. Tailoring the model to emails in particular will make it easier to do
things like selectively clear emails when people unsubscribe from particular
email types, or seamlessly handle using the same email on multiple realms.
Both the queue processor and ScheduledJob emails need to sometimes pass a
to_user_id and sometimes pass a to_email, and it's more convenient to just
have one function that they can call that can handle either.
Also removes the now redundant send_email_to_user.
The MitUser table was removed in df525ad.
confirm_mituser.html could have been accessed through the last few lines of
confirmation/views.py:
templates.insert(0, 'confirmation/confirm_%s.html'
% (obj._meta.model_name,))
The commit message on df525ad suggests there was another way
confirm_mituser.html could have been called, but I don't currently see
evidence for it in the code.
Usually we write translation expressions as `{{t ... }}`, but `{{ t ... }}`
is equally valid as far as Handlebars is concerned, and it matches how we
usually write simple variable substitutions, as `{{ ... }}`. So occasionally
someone writes `{{ t ... }}`; currently there are two examples of this
in the codebase, in `settings/bot-{settings,list-admin}.handlebars`.
Probably it'd be good to pick a style and enforce it uniformly, but
until we do, the other style shouldn't break translation.
- For threaded workers:
Django's autoreloader catches SIGQUIT(3) to reload the program. If
a process being watched by autoreloader exits with status code 3,
reloader will restart the process. To reload, we send SIGUSR1(10)
signal from consumers to a handler in process_queue which then
exits with status code 3.
- For single worker per process:
Catch the SIGUSR1 and quit; supervisorctl will restart the worker
automatically.
Fixes#5512
This system hasn't been in active use for several years, and had some
problems with it's design. So it makes sense to just remove it to declutter
the codebase.
Fixes#5655.
This new library is intended to make it easy for management commands
to access a realm or a user in a realm without having to duplicate any
of the annoying parsing/extraction code.
Make it less likely that further development will break compatibility with
ZULIP_ADMINISTRATORs of the form "name <email>".
Note that the suggested value for this setting has been
'zulip-admin@example.com' for a while, so hopefully this commit causes no
change for most installations.
Once we implement org_type-specific features, it'll be easy to change a
corporate realm to a community realm, but hard to go the other way. The main
difference (the main thing that makes migrating from a community realm to a
corporate realm hard) is that you'd have to make everyone sign another terms
of service.
Now REs have moved to template module. This commit adds a condition
to use trans_real module if the Django version is less than 1.11 else
use template module.
While running queue processors multithreaded will limit the
performance available to very small systems, it's easy to fix that by
adding more RAM, and previously, Zulip didn't work on such systems at
all, so this is unambiguously an improvement there.
Fixes#32.
Fixes#34.
(Commit message expanded significantly by tabbott.)
Previously, all notification preference setting had a dedicated test
and setter. Now, all are handled through a modular function using the
property_types framework.
This commit is a step towards the goal of replacing most of the
send_future_email pathway with a call to send_email.
Note that this commit changes the default value of sender from "Zulip
<NOREPLY_EMAIL_ADDRESS>" to "NOREPLY_EMAIL_ADDRESS". NOREPLY_EMAIL_ADDRESS
will soon be changed to have the Zulip in front.
This commit replaces all uses of django.core.mail.send_mail with send_email,
other than in the password reset flow, since that code looks like it is just
a patch to Django's password reset code.
The send_email function is in a new file, since putting it in
zerver.lib.notifications would create an import loop with confirmation.models.
send_future_email will soon be moved into email.py as well.
This fixes a performance problem where we were previously starting up
a full Django process (~0.7s even on a fast machine) every time a new
email came in, potentially allowing users to accidentally DoS a Zulip
server. Now, we just post over HTTPS, allowing the existing thread
pool support to do its job.
- Add script wrapper to communicate postfix pipe with django web server
over HTTP(S). It uses shared_secret authentication mode.
- Add django view to process messages from email mirror server.
- Clean management command `email-mirror`. Left just functional
for cron email processing.
- Add routes for new tornado view.
- Change pipe script in master process postfix config template
based on updated script.
- Add tests.
Tweaked by tabbott to adjust the directory and set better defaults.
Fixes#2421.
Some Handlebars strings contained whitespaces characters at their ends.
With this, such characters are removed, as well as multiple spaces
(like the ones produced by code indentation).
This also includes a couple of fixes that removes spaces that were
intentionally placed before/after the string to translate.
This better sets expectatations for the fact that in Zulip, the
Organization settings UI is available read-only to non-administrator
users.
Tweaked by tabbott to update some additional references.
This system was quite complicated, and never had great semantics.
Eventually, we'll want some other system for gating which server
should generate digest emails for which realm controlled via the
database.
In this commit we just change the upload_avatar_image function to accept
two user_profiles acting_user_profile and target_user_profile. Basically
email param is dropped for a target_user_profile so that avatar's could
be moved lateron to user id based storage.
datetime.utcnow() is a timezone-naive datetime. The Django ORM interprets it
in the settings.TIME_ZONE timezone (e.g. 'America/New_York' in the
development server). We perhaps haven't noticed errors yet since with
'America/New_York' all it means is that emails are sent 5 hours early, or a
slightly different set of messages are included in the digest.
When you pass a naive datetime to the Django ORM, it uses settings.TIME_ZONE
for the time zone. In the development environment, both settings.TIME_ZONE
and datetime.now() use 'America/New_York', so there is no change in behavior
there. (fromtimestamp with no tz argument uses the same timezone as
datetime.now)
We are soon going to change settings.TIME_ZONE to UTC, so need to remove
naive datetimes from queries to the ORM.
