The value in the stats file can get outdated if the queue hasn't done
enough iterations to update the stats file for a while. The queue size
output by rabbitmqctl list_queues is more up to date, and empirically
tends to agree with the value in the stats file (when the stats file is
fresh).
There are three functional side effects:
• Correct an insignificant but mathematically offensive bias toward
repeated characters in generate_api_key introduced in commit
47b4283c4b4c70ecde4d3c8de871c90ee2506d87; its entropy is increased
from 190.52864 bits to 190.53428 bits.
• Use the base32 alphabet in confirmation.models.generate_key; its
entropy is reduced from 124.07820 bits to the documented 120 bits, but
now it uses 1 syscall instead of 24.
• Use the base32 alphabet in get_bigbluebutton_url; its entropy is
reduced from 51.69925 bits to 50 bits, but now it uses 1 syscall
instead of 10.
(The base32 alphabet is A-Z 2-7. We could probably replace all of
these with plain secrets.token_urlsafe, since I expect most callers
can handle the full urlsafe_b64 alphabet A-Z a-z 0-9 - _ without
problems.)

PostgreSQL packages for Ubuntu run "initdb" without specifying locale
on installation. It means that the default template
database (template1) is created by the system default locale. If the
system default locale is non UTF-8 compatible encoding such as
en_US.ISO-8859-15, "zulip" database is also created non UTF-8
compatible encoding such as LATIN9.
You can reproduce this case by running the following script:
apt update
apt install -y locales
locale-gen en_US.ISO-8859-15
update-locale LANG=en_US.ISO-8859-15 LANGUAGE=en_US:
apt install -y wget

The combination of `--force --noop` is potentially confusing, but
currently `--noop` makes no sense without `--force`, as it will prompt
and then not make changes.
Make `--noop` skip the prompt as well.
Fixes#12868.
We now also include python version in the format
'major.minor.patchlevel', when generating hash for a
requirement file. This was necessary since packages tend to
break on different versions of python, so it is important to
track the version on which the venv was setup.
WARN: This commit will force all zulip venvs to be recreated.
We were already using packages names along with their versions
to generate hash for the requirement file, as we were passing
the `.txt` files to the hash_reqs file instead of intended `.in` files
for which the functions in this file was originially designed.
Changed the expand_reqs_helper function to adapt for the `.txt` files.
The contents in the database are unchanged across the PostgreSQL
restart; as such, there is no reason to invalidate the caches.
This step was inherited from the general operating system upgrade
documentation. When Python versions change, such as during OS
upgrades, we must ensure that memcached is cleared. However, the
`do-release-upgrade` process uninstalled and upgraded to a new
memcached, as well as likely restarted the system; a separate step for
OS upgrades to restart memcached is thus unnecessary.
pg_upgradecluster has two possibilities for `--method`: `dump`, and
`upgrade`. The former is the default, and does a `pg_dump` of all of
the databases in the old cluster and feeds them into the new cluster.
This is a sure-fire way of getting the same information in both
databases, but may be extremely slow on large databases, and is
guaranteed to fail on servers whose databases take up >50% of their
disk.
The `--method=upgrade` method, by contrast, uses pg_upgrade to copy
the raw database data file over to the new cluster, and then fiddles
with their internal structure as needed by the upgrade to let them be
correct for the new version[1]. This is slightly faster than the
dump/load method, since it skips the serialization step, but still
requires that there be enough space on disk for both old and new
versions at once. `pg_upgrade` is currently supported for all
versions of PostgreSQL from 8.4 to 12.
Using `pg_upgrade` incurs slightly more risk, but since the it is
widely used by now, using it in the relatively-controlled Zulip server
environment is reasonable. The expected worst failure is failure to
upgrade, not corruption or data loss.
Additionally passing `--link` uses hardlinks to link the data files
into both the old and new directories simultaneously. This resolve
both the runtime of the operation, as well as the disk space usage.
The only potential downside to this is that as soon as writes have
occurred on the upgraded cluster, the old cluster can no longer be
started. Since this tooling intends to remove the old cluster
immediately after the upgrade completes successfully, this is not a
significant drawback.
Switch to using `--method=upgrade --link`. This technique spits out
two shell scripts which are expected to be run after completion of the
upgrade; one re-analyzes the statistics, the other does an `rm -rf` of
the data where it is still hardlinked in the old cluster. Extract the
location of these scripts from parsing the `pg_upgradecluster` output;
since the path is not static, we must rely on it being relatively easy
to parse. The risk of the path changing is lower, and has more
obvious failure modes, than inserting the current contents of these
upgrade steps into the overall `upgrade-postgres`.

Although mktemp is deprecated due to security issues, this is not a
security issue.
The security problems with mktemp happen when you open the resulting
filename (without O_EXCL) in a publicly writable directory, because
then someone else might have predicted the filename and created or
symlinked or hardlinked something there between the mktemp and the
open, causing you to write to a file you didn’t expect.
Here we don’t open the resulting filename, we symlink to it. symlink
will refuse to clobber an existing file, and we handle the error that
arises from this case. This is the normal way to atomically create a
symlink.
We should still replace mktemp because it’s deprecated, but we can’t
replace it with a function that creates the temporary file. Instead
we build a random filename ourselves.

Running `pg-upgradecluster` runs the `CREATE TEXT SEARCH DICTIONARY`
and `CREATE TEXT SEARCH CONFIGURATION` from
`zerver/migrations/0001_initial.py` on the new PostgreSQL cluster;
this requires that the stopwords file and dictionary exist _prior_
to `pg_upgradecluster` being run.
This causes a minor dependency conflict -- we do not wish to duplicate
the functionality from `zulip::postgres_appdb_base` which configures
those files, but installing all of `zulip::postgres_appdb_tuned` will
attempt to restart PostgreSQL -- which has not configured the cluster
for the new version yet.
In order to split out configuration of the prerequisites for the
application database, and the steps required to run it, we need to be
able to apply only part of the puppet configuration. Use the
newly-added `--config` argument to provide a more limited `zulip.conf`
which only applies `zulip::postgres_appdb_base` to the new version of
Postgres, creating the required tsearch data files.
This also preserves the property that a failure at any point prior to
the `pg_upgradecluster` is easily recoverable, by re-running
`zulip-puppet-apply`.
Otherwise, the useradd command will fail during the DigitalOcean
1-Click App installation because the install script is called
twice during the whole process. Plus the Zulip install script
is designed to be idempotent and this bug compromises that.
The value is a holdover from when it controlled runtime behavior,
which it no longer does.
Stop taking a DEPLOYMENT_TYPE, which is unused; the python code only
care about if the option exists, not its value.
These are more correct to the sense of "is this a service we
configured for Zulip", and removes potential confusion around the 0/1
values being backwards from how binary is usually interpreted.
Using checks of `,$PUPPET_CLASSES,` is repetitive and error-prone; it
does not properly deal with `zulip_ops::` classes, for instance, which
include the `zulip::` classes.
As alluded to in ca9d27175b, this can be fixed by inspecting the
classes that would be applied, using `puppet --write-catalog-summary`.
We work around the chicken-and-egg problem alluded to therein by
writing out as complete `zulip.conf` as would be necessary, before
running puppet and removing the sections we then know to not be
needed.
Unfortunately, there are two checks for `$PUPPET_CLASSES` which cannot
be switched to this technique, as they concern errors that we wish to
catch quite early, and thus before we have puppet installed. Since we
expect failures of those to only concern warnings, and only be
mistakenly omitted for internal `zulip_ops::` classes, this seems a
reasonable risk to admit in exchange for catching common errors early.
When supervisor is first installed, it is started automatically, and
creates the socket, owned by root. Subsequent reconfiguration in
puppet only calls `reread + update`, which is insufficient to apply
the `chown = zulip:zulip` line in `supervisord.conf`, leaving the
socket owned by `root` and the last part of the installation unable to
restart `supervisor` services as the `zulip` user. The `chown` line
in `scripts/lib/install` exists to paper over this.
Add a separate exec target for changes to `supervisord.conf` itself,
which restarts the full service. This leaves the default `restart`
action on the service for the lightweight `reread + update` action,
which is more common.
We use `systemctl` only on redhat-esque builds, because CI runs
Ubuntu, but init is not systemd in that context. `systemctl reload`
is sufficient to re-apply the socket ownership, but a full `restart`
and not `reload` is necessary under `/etc/init.d/supervisor`.
This is based on the existing steps in the documentation, with
additional changes now that the PostgreSQL version is stored in
`/etc/zulip/zulip.conf`.
49a7a66004 and immediately previous commits began installing
PostgreSQL 12 from their apt repository. On machines which already
have the distribution-provided version of PostgreSQL installed,
however, this leads to failure to apply puppet when restarting
PostgreSQL 12, as both attempt to claim the same port.
During installation, if we will be installing PostgreSQL, look for
other versions than what we will install, and abort if they are
found. This is safer than attempting to automatically uninstall or
reconfigure existing databases.
This allows for installing from-scratch with a different pinned
version of PostgreSQL, and provides a single place to change when the
default should increase.
Using `/etc/init.d/postgresql` as the detection of if Postgres is on
the server is incorrect, because this line runs _before_ puppet and
any packages are installed. Thus, it cannot tell the difference
between a new Ubuntu one-host first-time-install without PostgreSQL
yet, and one which is merely a front-end and will never have
PostgreSQL. This leads to failures in first-time installs:
```
Error: Evaluation Error: Error while evaluating a Function Call,
Could not find template 'zulip/postgresql//postgresql.conf.template.erb'
```
The only way to detect if PostgreSQL will be present in the _end_
state of the install is to examine the puppet classes that are
applied.
To do this, we must inspect `PUPPET_CLASSES`. Unfortunately, this can
be fragile to subclassing (e.g. `zulip_ops::postgres_appdb`). We
might desire to use `puppet apply --write-catalog-summary` to deduce
the _applied_ classes, which would unroll the inheritance; however,
this causes a chicken-and-egg problem, because `zulip.conf` must be
already written out (including a value for `postgresql.version`, if
necessary!) before such a puppet run could successfully complete.
Switch to predicating the `postgresql.version` key on the puppet
classes that are known to install postgres.
Support for Xenial and Stretch was removed (5154ddafca, 0f4b1076ad,
8944e0ad53, 79acd5ae40, 1219a2e854), but not all codepaths were
updated to remove their conditionals on it.
Remove all code predicated on Xenial or Stretch. debathena support
was migrated to Bionic, since that appears to be the current state of
existing debathena servers.
0f4b1076ad removed Ubuntu 16.04 "xenial" and Debian 9 "stretch" from
the printed list of supported operating systems, but left them in the
verification check that controls if that message is printed,
effectively continuing to support them.
Conversely, 439f0d3004 added Ubuntu 20.04 "focal" to the check, but
not to the printed list.
Synchronize to check and print the right supported distributions:
Ubuntu 18.04 "bionic", Ubuntu 20.04 "focal", and Debian 10 "buster".
The previous commit removed the only behavior difference between the
two flags; both of them skip user/database creation, and the tables
therein.
Of the two options `--no-init-db` is more explicit as to what it does,
as opposed to just one facet of when it might be used; remove
`--remote-postgres`.
Since `--postgres-missing-dictionaries` edits `/etc/zulip/zulip.conf`,
it interferes with the intent of `--no-overwrite-settings`.
Make the two settings conflict, to prevent this unclear state.
The `--no-init-db` option previously only controlled if
`initialize-database` was run, which sets up the tables inside the
database. If PostgreSQL was installed locally, it still attempted to
create the user and empty database.
This fails on hosts which are remote PostgreSQL hosts, and not
application hosts, as:
- They may already have a local database, and while
`initialize-datbase` will detect and offer to abort if one is
found,`--no-init-db` seems like it should be the option to not
overwrite it
- `flush-memcached` requires that a local venv be installed, which it
often is not on non-frontend machines.
Skip the database configuration when run with `--no-init-db`.
Since we now support Postgres versions from 10 to 12, we might as well
have new installations start on Postgres 12 to avoid unnecessary
migration/upgrade work.
We would prefer to use the postgres packages from Postgres themselves,
if available. However, this requires ensures that, for existing
installs, we preserve the same version of postgres as their base
distribution installed.
Move the version-determination logic from being computed at puppet
interpolation time, to being computed at install time and pinned into
zulip.conf.
This is a prep commit. Running terminate-psql-sessions command on
docker-zulip results in the script exiting with non-zero exit status

we don't terminate the session created by terminate-psql-sessions.

While this functionality to post slow queries to a Zulip stream was
very useful in the early days of Zulip, when there were only a few
hundred accounts, it's long since been useless since (1) the total
request volume on larger Zulip servers run by Zulip developers, and
(2) other server operators don't want real-time notifications of slow
backend queries. The right structure for this is just a log file.
We get rid of the queue and replace it with a "zulip.slow_queries"
logger, which will still log to /var/log/zulip/slow_queries.log for
ease of access to this information and propagate to the other logging
handlers. Reducing the amount of queues is good for lowering zulip's
memory footprint and restart performance, since we run at least one
dedicated queue worker process for each one in most configurations.
Yes, it's slightly janky to create an
argparse.Namespace object like this, but it
saves us from shelling out to a script whose
only real value-add is parsing a single
`threshold_days` argument.
This saves about 130ms for a no-op provision.
We try to avoid importing Django settings unless
we really need them, since we want this program
to run very quickly during `provision` (when
secrets have already been generated earlier).
Since in travis we don't have root access so we used to add different
srv path. As now we shifted our production suites to Circle CI
we don't need that code so removed it.

Previously, the send_custom_email code path leaked files in paths that
were not `.gitignored`, under templates/zerver/emails.
This became problematic when we added automated tests for this code
path, as it meant we leaked these files every time `test-backend` ran.
Fix this by ensuring all the files we generate are in this special
subdirectory.
Since now we want to use production suites on Circle CI so there
is no need to set TRAVIS in env while running scripts.
CIRCLECI is set default in the enviroment of Circle CI builds
so we can use it directly.
Also Travis CI had rabbitmq-server installed so we had to add workaround
in install script to avoid the error. That workaround is removed.
We now have two functions related to digests
for processes:
is_digest_obsolete
write_digest_file
In most cases we now **wait** to write the
digest file until after we've successfully
run a process with its new inputs.
In one place, for database migrations, we
continue to write the digest optimistically.
We'll want to fix this, but it requires a
little more code cleanup.
Here is the typical sequence of events:
NEVER RUN -
is_digest_obsolete returns True
quickly (we don't compute a hash)
write_digest_file does a write (duh)
AFTER NO CHANGES -
is_digest_obsolete returns False
after reading one file for old
hash and multiple files to compute
hash
most callers skip write_digest_file
(no files are changed)
AFTER SOME CHANGES -
is_digest_obsolete returns False
after doing full checks
most callers call write_digest_file
*after* running a process
I remove `is_force` from `file_or_package_hash_updated`
and modernize its mypy annotations.
If `is_force` is `True`, we just now run the thing
we want to force-run without having to call
`file_or_package_hash_updated` to expensively
and riskily return `True`.
Another nice outcome of this change is that if
`file_or_package_hash_updated` returns `True`,
you can know that the file or package has
indeed been updated.
For the case of `build_pygments_data` we also
skip an `os.path.exists` check when `is_force`
is `True`.
We will short-circuit more logic in the next
few commits, as well as cleaning up some of
the long/wrapper lines in the `if` statements.
We stopped using tsearch-extras in Zulip 2.1.0 after Anders figured
out how to achieve its goals with native postgres. However, we never
did a `DROP EXTENSION` on systems thta had upgraded, which meant that
backups created on systems originally installed with Zulip 2.0.x and
older, and later upgraded to Zulip 2.1.x, could not be restored on
Zulip servers created with a fresh install of Zulip 2.1.x.
We can't do this with a normal database migration, because DROP
EXTENSION has to be done as the postgres user, so we add some custom
migration code in the upgrade-zulip-stage-2 tool.
It's safe to run this whenever tsearch_extras.control is installed because:
* Zulip is AFAIK the only software that ever used tsearch_extras.
* The package was only installed via puppet on production servers configured to
run a local Zulip database.
* We'll only run this code once per system, because it removes the
package and thus the control files.

After some testing, I've confirmed that this seems to behave

Tornado being the process of restarting compared with the previous
version, as each individual process is only down for a short time,
rather than all of them being down at once.
Missing commas in the definition of all the queues to check meant that it would be looking for queues with concatenated names, rather than the correct ones. Added the commas.
Used get_venv_dependencies function to return the correct dependencies

COMMON_YUM_DEPENDENCIES in provision and create-production-venv.
In virtualenv ≥ 20, the site_packages variable was removed from
activate_this.py. To avoid a KeyError, replace
activate_locals['site_packages'] with os.path.join(venv, 'lib',
python_version), where python_version is the 'pythonX.Y' name of the
directory where site-packages resides in the virtualenv.
Fixes#14025.
Added a get_venv_dependencies() function in setup_venv.py which
returns VENV_DEPENDENCIES according to the vendor and os_version.
The reason for adding this function was because python-dev will be

support for Focal VENV_DEPENDENCIES should to be os_version dependent.

"Zulip Voyager" was a name invented during the Hack Week to open
source Zulip for what a single-system Zulip server might be called, as
a Star Trek pun on the code it was based on, "Zulip Enterprise".
At the time, we just needed a name quickly, but it was never a good
name, just a placeholder. This removes that placeholder name from
much of the codebase. A bit more work will be required to transition
the `zulip::voyager` Puppet class, as that has some migration work
involved.
These docstrings hadn't been properly updated in years, and bad an
awkward mix of a bad version of the user-facing documentation and
details that are no longer true (e.g. references to "Voyager").
(One important detail is that we have real documentation for this
system now).
This legacy cross-realm bot hasn't been used in several years, as far
as I know. If we wanted to re-introduce it, I'd want to implement it
as an embedded bot using those common APIs, rather than the totally
custom hacky code used for it that involves unnecessary queue workers
and similar details.

Zulip has had a small use of WebSockets (specifically, for the code
path of sending messages, via the webapp only) since ~2013. We
originally added this use of WebSockets in the hope that the latency
benefits of doing so would allow us to avoid implementing a markdown
local echo; they were not. Further, HTTP/2 may have eliminated the
latency difference we hoped to exploit by using WebSockets in any
case.
While we’d originally imagined using WebSockets for other endpoints,
there was never a good justification for moving more components to the
WebSockets system.
This WebSockets code path had a lot of downsides/complexity,
including:
* The messy hack involving constructing an emulated request object to
hook into doing Django requests.
* The `message_senders` queue processor system, which increases RAM
needs and must be provisioned independently from the rest of the
server).
* A duplicate check_send_receive_time Nagios test specific to
WebSockets.
* The requirement for users to have their firewalls/NATs allow
WebSocket connections, and a setting to disable them for networks
where WebSockets don’t work.
* Dependencies on the SockJS family of libraries, which has at times
been poorly maintained, and periodically throws random JavaScript
exceptions in our production environments without a deep enough
traceback to effectively investigate.
* A total of about 1600 lines of our code related to the feature.
* Increased load on the Tornado system, especially around a Zulip
server restart, and especially for large installations like
zulipchat.com, resulting in extra delay before messages can be sent
again.
As detailed in
https://github.com/zulip/zulip/pull/12862#issuecomment-536152397, it
appears that removing WebSockets moderately increases the time it
takes for the `send_message` API query to return from the server, but
does not significantly change the time between when a message is sent
and when it is received by clients. We don’t understand the reason
for that change (suggesting the possibility of a measurement error),
and even if it is a real change, we consider that potential small
latency regression to be acceptable.
If we later want WebSockets, we’ll likely want to just use Django
Channels.

Our recent fixes to using the system's configured memcached settings
broke populate_db, because its hacky clear_database helper is called
with a hacked-up settings module.
We fix this by first moving this out-of-place code from models.py into
populate_db, and then saving the settings required to access memcached
so that we can use them in clear_database.
We also fix a mypy erorr in flush-memcached that matches the same
issue fixed in clear_database.
This simplifies the RDS installation process to avoid awkwardly

Ultimately, this isn't an effective way to monitor this queue; we want

But until we add the monitoring we want, it makes sense to leave this

As predicted in https://www.kb.cert.org/vuls/id/319816/, a malicious
worm is beginning to spread across the npm ecosystem through package
postinstall scripts. Only instead of direct self-replicating code,
the replication vector is the temptation to monetize postinstall
scripts by polluting the console logs with paid advertisements. The
effect will be the same unless we all put a stop to this while we
still can.
Apply the recommended VU#319816 workaround, which is to disable
lifecycle scripts when installing npm packages. The only fallout is:
* node-sass can’t run because it uses compiled native code; we replace
it with Dart Sass.
* phantomjs-prebuilt doesn’t download the binary at install time; we

The comment that tabbott edited into my commit while wimpifying this
function is wrong on multiple levels.
Firstly, the way in which users might be “running our scripts” was
never relevant. `__file__` is not the script that the user ran, it’s
zulip_tools.py itself. What matters is not how the user ran the
script, but rather how zulip_tools was imported. If zulip_tools was
imported as scripts.lib.zulip_tools, then `__file__` must end with
`scripts/lib/zulip_tools.py`, so running dirname three times on it is
fine. In fact, in Python ≥ 3.4 (we don’t support anything older),
`__file__` in an imported module is always an absolute path, so it
must end with `scripts/lib/zulip_tools.py` in any case.
(At present, there’s one script that imports lib.zulip_tools, and the
installer runs scripts/lib/zulip_tools.py as a script, but those uses
don’t hit this function.)
Secondly, even if we do care about `__file__` being a funny relative
path, there’s still no reason to have two calls to `realpath`.
`realpath(dirname(dirname(dirname(realpath(…)))))` is equivalent to
`dirname(dirname(dirname(realpath(…)))), as the inner `realpath` has
already canonicalized symlinks at every level.
This version also deals with `__file__` being a funny relative
path (assuming none of scripts, lib, and zulip_tools.py are themselves
symlinks), while making fewer `lstat` calls than either of the above
constructions.

Apparently, the `chown -R` would never run if the original clone

This actually happens somewhat often, generally when we're doing a series of

Few folks will be upgrading from versions of Zulip old enough to not

to older dependencies having been removed.
Apparently, while upgrade-zulip-from-git always ensures that zulip
deployment directories are owned by the Zulip user, unpack-zulip (aka
the tarball code path) has them owned by root.
The user ID detection logic in su_to_zulip's helper get_zulip_uid was
intended to support both development environments (where the user ID
might vary) and production environments. For development
environments, the existing code is fine, but given this unpack-zulip
permissions issue, we need to have code to fallback to 'zulip' if the
detection logic detects the "zulip" user has having UID 0.

This makes it possible to add --skip-purge-old-deployments in the
deploy_options section of /etc/zulip/zulip.conf, and control whether
old deployments are purged automatically on a system.
We still need to do https://github.com/zulip/zulip/issues/10534 and
probably also to add these arguments to be directly passed into
upgrade-zulip, but that can wait for future work.
Fixes#10946.
This commit works by vendoring the couple functions we still use from
puppetlabs stdlib (join and range), but removing the rest of the
puppetlabs codebase, and of course cleaning up our linter rules in the
process.
Fixes#7423.
Since yarn has a package.json conveniently available, we can parse
that with jq, saving the expensive operation of starting up yarn.
This saves ~300ms in a no-op provision.
This makes it possible for the Puppet codebase to access the path to
the relevant /home/zulip/deployments type directory that puppet was
run from, which in turn makes it possible to safely call scripts from
here.
Based on work by Rein Zustand.
Apparently, we were incorrectly expressing the paths in the
caches_in_use data structures for these two cache-cleaning algorithms,
resulting in the default threshhold_days algorithm controlling which
caches could be garbage-collected. While the emoji one was just a
performance optimization for upgrade-zulip-from-git, it was possible
for the main `node_modules` cache in use in production to be GCed,
resulting in LaTeX rendering being broken.
This fixes an actual user-facing issue in our mobile push
notifications documentation (where we were incorrectly failing to
quote the argument to `./manage.py register_server` making it not
work), as well as preventing future similar issues from occurring
again via a linter rule.
Apparently, on Debian stretch, the gnupg package isn't installed by
default, which means that our `apt-key add` commands were failing with
these errors on an ultra-minimal Debian installation:
+ apt-key add ./scripts/setup/packagecloud.asc
E: gnupg, gnupg2 and gnupg1 do not seem to be installed, but one of them is required for this operation
+ apt-key add ./scripts/setup/pgroonga-debian.asc
E: gnupg, gnupg2 and gnupg1 do not seem to be installed, but one of them is required for this operation
Fixes#10480.
The original code was actually broken, in that it checked the wrong
path, but it didn't matter because it used `ln -nsf`.

Previously, we unconditionally tried to restart the Tornado process
name corresponding to the historically always-true case of a single
Tornado process. This resulted in Tornado not being automatically
restarted on a production deployment on servers with more than one
Tornado process configured.
This library was absolutely essential as part of our Python 2->3
migration process, but all of its calls should be either no-ops or
encode/decode operations.
Note also that the library has been wrong since the incorrect
refactoring in 1f9244e060.
Fixes#10807.
This commit allows specifying Subject Alternative Names to issue certs
for multiple domains using certbot. The first name passed to certbot-auto
becomes the common name for the certificate; common name and the other
names are then added to the SAN field. All of these arguments are now
positional. Also read the following for the certbot syntax reference:
https://community.letsencrypt.org/t/how-to-specify-subject-name-on-san/Fixes#10674.
By far the dominant cause of errors when installing apt packages is
not having the Universe repository enabled in Ubuntu bionic (this
seems to have started happening a lot recently; I wonder if Ubuntu
changed the defaults for new server installs or something?).
In any case, providing that suggestion in the error output should help
reduce these a lot.
This allows our Tornado monitoring to correctly report whether
multiple configured Tornado processes are running.
This setup isn't ideal, in that it can't detect cases where the wrong
set of Tornado processes are running, but it's nice and simple and
should catch most actual problems.
Fixes#10706.
Issue: Before this commit, the `refname` positional argument to
`upgrade-zulip-from-git` script would run successfully for a branch
name on the given remote, but the script would fail if it was
provided with a tag or commit ID.
Solution: 'git clone -q -b refname LOCAL_GIT_CACHE_DIR deploy_path`
would be split into two commands:
1.) `git clone -q LOCAL_GIT_CACHE_DIR deploy_path`
2.) `git checkout -b deploy_timestamp refname` which makes a new
branch with the same name as the timestamp used in make_deploy_path.
Adds an optional argument `--remote-url` to specify the remote URL.
Command line remote URL will be given preference above the one
in /etc/zulip/zulip.conf.
Fixes#6092.

We use it to drop privileges from root to other users in the installer
process (which ideally, we would remove, but it will take some
annoying refactoring).
This should generally be safe to do, since the default sudo
permissions only allow root to use it anyway.
See https://github.com/zulip/zulip/issues/10036 for the follow-up
issue of removing the need to do this.
This dramatically reduces the Tornado downtime when restarting a Zulip
server, which is generally the most significant source of user-facing
bad experiences.
Because we renamed the "google" iconset to be the modern Google set,
not what is now called the "googleblob" icon set, we need to make sure
that our usually correct policy of not overwriting image files under
`prod-static/` doesn't apply to files potentially being copied in for
the emoji images.
We fix this by just deleting the `images-google-64` directory on
upgrade if it contains the googleblob version of the "hotdog" emoji.
Fixes#10038.
Previously, we were having issues installing on Debian Stretch with
non-English locales, because `locale-gen` actually doesn't take a
locale as an argument (and thus `locale-gen en_US.UTF-8` did nothing).
We should instead be calling localedef directly.
Thanks to Tom Daff for debugging this.
Fixes#10629.
For building Zulip in an environment where a custom CA certificate is
required to access the public Internet, one needs to be able to
specify that CA certificate for all network access done by the Zulip
installer/build process. This change allows configuring that via the
environment.
Thanks to changes in restart-server, this is now already happening there.
(The restart-server changes were required to ensure that if the
upgrade failes and one just does
/home/zulip/deployments/next/restart-server to recover, the right
thing happens; so this is the correct resolution to the conflict).

This flag is used to track which user/message pairs correspond to an
active mobile push notification, that should potentially be cleared
when the user reads the message.
This flag should never appear on a message that is also marked as
read; eventually we may want a cron job to check for that condition.
We include a partial index on UserMessage for this flag.
Apparently, our Python 3 conversion for the early-migrations logic
here was incorrect, and as a result we never set
need_create_large_indexes to True (because we were checking whether a
`bytes` was inside a list of `str`s).
The simplest fix would be to just add a `.decode()` in one place, but
this refactor to just decode at the beginning is a lot more readable.
