For some reason, we have the USING_PGROONGA setting on in development
right now. I'm going to disable that in another commit to match what
we're doing in production, but we'll still want that setting to work
in development.
The problem here was that process_fts_updates only attempted to read
the USING_PGROONGA setting from a /etc/zulip/zulip.conf source, and
thus would just not be updating the index in development.
We weren't compressing SVG, while at the same time were incorrectly
compressing octet-stream (Which meant downloading .tar.gz files in
Chrome would get double-compressed).
The old limits were such that these would sometimes oscillated too
high and page erroneously. The purpose of this check is to prevent
large memory leaks, and will still achieve that with a higher limit.
Since we've found that it's fairly frequent that we want to recommend
to developers that they upgrade to a version of Zulip from Git, it
makes sense to include that by default.
It's needed by scripts/install-yarn.sh. This hadn't been discovered
because most systems end up having curl installed even though it isn't
technically a required package.
Whenever you restarted supervisord services, we'd end up leaking one
process from the process_queue group, eventually resulting in running
out of memory.
Fixes#6184.
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.
The Zulip server's settings are only available if process-fts-updates
is running is on the same server as a Zulip production deployment. So
we instead check whether we have pgroonga configured in
/etc/zulip/zulip.conf.
This is only actually used in our `wal-e` setup, which is in
zulip_ops::postgres_common. (In fact the only mentions of `gevent` in
our whole Git history are for `wal-e`.) So remove where we mention it
on the broader zulip::postgres_common module, and move it where it's
needed.
This follows up on 98cef0ab4 by eliminating the only dependency
outside of the `zulip_ops` Puppet tree on a system Python-library
package which isn't available in `trusty` for Python 3.
This follows up on 207cf6302 from last year to clean up cases that
have apparently popped up since then. Invoking the scripts directly
makes a cleaner command line in any case, and moreover is essential
to how we control running a Zulip install as either Python 2 or 3
(soon, how we always ensure it runs as Python 3.)
One exception: we're currently forcing `provision` in dev to run
Python 3, while still running both Python 2 and Python 3 jobs in CI.
We use a non-shebang invocation to do the forcing of Python 3.
In some of these contexts, we may still be *using* the Python 2
version, but at least this should eliminate running into
`ImportError`s one by one in scripts that run outside a virtualenv,
as we update their shebangs to refer to Python 3.
Several Python libraries we use don't come in Python 3 versions on
trusty: gevent, boto, twisted, django, django-tagging, whisper.
The latter two don't come in Python 3 versions even on xenial.
So some work required before we can actually switch the code that
relies on those libraries to run as Python 3 -- probably the best
solution will be to backport them all in our apt repo. (All but
`whisper` are packaged in zesty; `whisper` upstream just grew Python 3
support this year.)
It's rare that there's value in having the log files get this big, and
these changes mean these log files should never consume more than a
few gigabytes.
And in particular, the server.log is far more important than the other
log files, and grows much faster, so we might as well spend most of
the space we are spending on that.
I estimate that the total size of log files from this is going to be
under 1-2GB, since 75MB (compressed size) * 10 (compressed logs) +
500MB (uncompressed size) = 1.25GB from server.log, and the rest is
negligible.
Fixes part of #5724.
Most of these log files are useless except a few minutes after an
event happens, and the aggregate effect of the originals size limits
meant that Zulip's logs could consume many gigabytes of disk.
The new logging strategy should limit our usage from supervisor logs
to at most 3 Gigabytes:
* 20 * 3 = 60MB per queue worker => <1GB.
* 100 * 10 = 1GB for Django and Tornado logs.
Fixes part of #5724.
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.)
Also puts them into a processing queue, though the queue processor
does nothing.
Rewritten by tabbott to avoid unnecessary database queries in
do_send_messages.
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.
- Enable `master` parameter for `uswgi` configuration.
It allows cleaning leaked processes if the parent
process is closed unexpectedly or with SIGKILL command.
Child processes follow to the master and kill themselves
after the main process.
Fixes#3855
- Add new 'missedmessage_email_senders' queue for sending missed messages emails.
- Add the new worker to process 'missedmessage_email_senders' queue.
- Split aggregation missed messages and sending missed messages email
to separate queue workers.
- Adapt tests for sending missed emails to the new logic.
Fixes#2607
Using `supervisorctl restart all` carried longer downtime (since it
just restarts everything at the same moment) and was less under our
control; I'm not sure it had any advantages.
