Fixes#13134 as the last commit in the series for this issue.
Solves the "The (?) should just be a target=_blank link to
/help/message-a-stream-by-email." part of the issue.
As a result, a bunch code managing the email hint popup can be deleted,
together with a node test for that.
So the reason 38f8cf612c seems
to be flaking is because the value of harry id switches between
1 and 2 in Xenial while in Bionic it would be fixed at 2. The
reason behind this is that Bionic ships with Python3.6 which
preserves dict insert order while Python3.5 that ships with Xenial
dont preserve the order. In initialize_stream_membership_dicts
we iterate user_data_map dict and the order in which the iteration
happens affects the ID of the users.
Papertrail sends requests with the content type
`application/x-www-form-urlencoded`, with the payload parameter holding the
JSON body. This commit fixes the papertrail integration to use the payload
parameter in the request's POST data instead of trying to parse the
request's entire body as JSON.

We have a very useful piece of code, _RateLimitFilter, which is
designed to avoid sending us a billion error emails in the event that
a Zulip production server is down in a way that throws the same
exception a lot. The code uses memcached to ensure we send each
traceback roughly once per Zulip server per 10 minutes (or if
memcached is unavailable, at most 1/process/10 minutes, since we use
memcached to coordinate between processes)
However, if memcached is down, there is a logging.error call internal
to the Django/memcached setup that happens inside the cache.set() call,
and those aren't caught by the `except Exception` block around it.
This ends up resulting in infinite recursion, eventually leading to
Fatal Python error: Cannot recover from stack overflow., since this
handler is configured to run for logging.error in addition to
logging.exception.
We fix this using a thread-local variable to detect whether we are
being called recursively.
This change should prevent some nasty failure modes we've had in the
past where memcached being down resulted in infinite recursion
(resulting in extra resources being consumed by our error
notifications code, and most importantly, the error notifications not
being sent).
Fixes#12595.
Otherwise Bootstrap doesn’t get minified, and also the minification
state is incorrectly reflected in the webpack cache.
The Terser plugin is used by default; we need to include it explicitly
to avoid removing it.
Switch from cssnano to clean-css because it’s noticeably faster.

There's no reason for this to be a category of error that emails the
server administrator, since there's a good chance that fixing it will
need to be done in the Zulip codebase, not administrator action.
cssnano reduces this to a constant in a production build. (We could
add postcss-calc if we wanted this reduced in development.)

Fixes#9401.
This adds a FAKE_EMAIL_DOMAIN setting, which should be used if
EXTERNAL_HOST is not a valid domain, and something else is needed to
form bot and dummy user emails (if email visibility is turned off).
It defaults to EXTERNAL_HOST.
get_fake_email_domain() should be used to get this value. It validates
that it's correctly set - that it can be used to form valid emails.
If it's not set correctly, an exception is raised. This is the right
approach, because it's undesirable to have the server seemingly
peacefully operating with that setting misconfigured, as that could
mask some hidden sneaky bugs due to UserProfiles with invalid emails,
which would blow up the moment some code that does validate the emails
is called.
Many of them are now automatically generated by autoprefixer, while
others are unnecessary based on .browserslistrc, and some were just
wrong (the linear-gradient based checkerboard pattern in lightbox has
been broken in Firefox for a while).

Apparently, due to poor naming of the outer capture group we use to
separate the actual match from the surrounding whitespace (etc.) we
use to determine if the syntax is a possible linkifier start/end, if
you created a linkifier using "name" as the capture group, we'd try to
compile a pattern with two capture groups called "name", which would

To replace DISTRIB_FAMILY, there’s now an os_families function using

It’s about as fast as node-sass (faster, according to their
benchmarks) and more flexible. Autoprefixer is neat: we can now go
delete all our -moz-, -webkit-, etc. lines and have them autogenerated
as necessary based on .browserslistrc.

We no longer use tsearch_extras, and the camo patch is irrelevant on
systemd systems (Xenial and newer). So we no longer need to
provide/install a PPA at all.
Closes#13027.

Now that we're implemented tsearch_extras in pure postgres, we no
longer need a custom extension. This should help us considerably, as
it means we no longer need to ship custom apt packages at all.

input to the first order in create field form in org settings.
- Added warning block to dev docs using _templates/layout.html
- Removed copy-pasted warning from install.md and requirements.md

There was a bug where the success banner stuck
around even after the export completed. We now
nicely fade and remove the banner upon a successful
population of the export in the table.
Fixes: #13045
02cfb47 removed a couple HTML tags that were
being used to sort the table. We fix this,
but disable filtering exports by marking the
input type as `hidden`. We use this approach as
it seems `list_render` doesn't like an
undefined `opts.filter.element`, which is
what happens if we simply remove the `filter`
key.
Follow up of commit 2a1305d. Replace all local variables named 'msgid'
with 'message_id' in all JS and HTML files, and adds a linter rule for
it as well.
Resolves#12952.
This requires part 1 (which can take hours to run but generally
doesn't require downtime) to be completed first.
This portion of the migration will require the server to be completely
down for a brief period; for chat.zulip.org with 250M UserMessage
rows, it took about 60s to run; that time will vary depending on
hardware details like whether the server has an SSD, but fundamentally
shouldn't be long.
Our upgrade-zulip and upgrade-zulip-from-git tools can apply this
migration correctly; nothing special needs to be done.
Fixes#13040.
As part of adding support for more than 2B UserMessage rows in a Zulip
server, we need to change UserMessage.id (a field we don't access but
is needed by Django) from an int to a bigint. This commit is a series
of migrations which create a `bigint_id` column and populates it correctly.
This migration will take a long time to run; on chat.zulip.org (a
server with a lot of history), it took about 4 hours to complete.
How to migrate with minimal downtime:
1. Run `upgrade-zulip-from-git` through this commit. It will install
migration 0238 and then more or less hang while applying migration
0239. Once migration 0238 is completed, however, your server should
be able to be started back up safely while migration 0239 is running.
2. Run `/home/zulip/deployments/next/scripts/restart-server` in a
separate terminal to get Zulip running again.
3. When the `upgrade-zulip-from-git` command finishes, it will
automatically re-restart the Zulip server, leaving you in a consistent
state and ready to do part 2 of the migration.
A useful `manage.py shell` query for checking the state after this
commit is consistent is this:
assert UserMessage.objects.exclude(bigint_id=F("id")).count() == 0
