0663b23d54 changed zulip-puppet-apply to
use the venv, because it began using `yaml` to parse the output of
puppet to determine if changes would happen.
However, not every install ends with a venv; notably, non-frontend
servers do not have one. Attempting to run zulip-puppet-apply on them
hence now fails.
Remove this dependency on the venv, by installing a system
python3-yaml package -- though in reality, this package is already an
indirect dependency of the system. Especially since pyyaml is quite
stable, we're not using it in any interesting way, and it does not
actually add to the dependencies, it is preferable to parsing the YAML
by hand in this instance.
When exception is raised inside an exception handler, Python 3
helpfully prints both tracebacks separated by “During handling of the
above exception, another exception occurred:”. But when we’re using
an exception handler to retry the same operation, multiple tracebacks
are just noise. Suppress the earlier one using PEP 409 syntax.

This means that in steady-state, `zulip-puppet-apply` is expected to
produce no changes or commands to execute. The verification step of
`setup-apt-repo` is quite fast, so this cleans up the output for very
little cost.
The class names need to be renamed even if we are not about to run
puppet ourselves; otherwise, deployments which rely on running puppet
themselves will still have the wrong class names.
These are respected by `urllib`, and thus also `requests`. We set
`HTTP_proxy`, not `HTTP_PROXY`, because the latter is ignored in
situations which might be running under CGI -- in such cases it may be
coming from the `Proxy:` header in the request.
Using `config_file.write()` only writes out what python stored of the
file; as such, it strips all comments and whitespace.
Use `crudini --set`, which only modifies the line whose contents are
changed.
There is only one PostgreSQL database; the "appdb" is irrelevant.
Also use "postgresql," as it is the name of the software, whereas
"postgres" the name of the binary and colloquial name. This is minor
cleanup, but enabled by the other renames in the previous commit.
The "voyager" name is non-intuitive and not significant.
`zulip::voyager` and `zulip::dockervoyager` stubs are kept for
back-compatibility with existing `zulip.conf` files.
This moves the puppet configuration closer to the "roles and profiles
method"[1] which is suggested for organizing puppet classes. Notably,
here it makes clear which classes are meant to be able to stand alone
as deployments.
Shims are left behind at the previous names, for compatibility with
existing `zulip.conf` files when upgrading.

Fingerprinting the config is somewhat brittle -- it requires either
custom bootstrapping for old (fingerprint-less) configs, and may have
false-positives.
Since generating the config is lightweight, do so into the .tmp files,
and compare the output to the originals to determine if there are
changes to apply.
In order to both surface errors, as well as notify the user in case a
restart is necessary, we must run it twice. The `onlyif`
functionality cannot show configuration errors to the user, only
determine if the command runs or not. We thus run the command once,
judging errors as "interesting" enough to run the actual command,
whose failure will be verbose in Puppet and halt any steps that depend
on it.
Removing the `onlyif` would result in `stage_updated_sharding` showing
up in the output of every Puppet run, which obscures the important
messages it displays when an update to sharding is necessary.
Removing the `command` (e.g. making it an `echo`) would result in
removing the ability to report configuration errors. We thus have no
choice but to run it twice; this is thankfully low-overhead.
The reason higher expected_time_to_clear_backlog were allowed for queues
during "bursts" was, in simpler terms, because those queues to which
this happens, intrinsically have a higher acceptable "time until cleared"
for new events. E.g. digests_email, where it's completely fine to take a
long time to send them out after putting in the queue. And that's
already configurable without a normal/burst distinction.
Thanks to this we can remove a bunch of overly complicated, and
ultimately useless, logic.
The race condition is described in the comment block removed by this
commit. This leaves room for another, remaining race condition
that should be virtually impossible, but nevertheless it seems
worthwhile to have it documented in the code, so we put a new comment
describing it.
As a final note, this is not a new race condition,
it was hypothetically possible with the old code as well.
We can compute the intended number of processes from the sharding
configuration. In doing so, also validate that all of the ports are
contiguous.
This removes a discrepancy between `scripts/lib/sharding.py` and other
parts of the codebase about if merely having a `[tornado_sharding]`
section is sufficient to enable sharding. Having behaviour which
changes merely based on if an empty section exists is surprising.
This does require that a (presumably empty) `9800` configuration line
exist, but making that default explicit is useful.
After this commit, configuring sharding can be done by adding to
`zulip.conf`:
```
[tornado_sharding]
9800 = # default
9801 = other_realm
```
Followed by running `./scripts/refresh-sharding-and-restart`.
This supports running puppet to pick up new sharding changes, which
will warn of the need to finalize them via
`refresh-sharding-and-restart`, or simply running that directly.
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).
This will let PyYAML link against LibYAML when PyYAML is next
installed. Due to virtualenv-clone, that won’t happen until the next
Python package removal anyway, so we don’t bother bumping
PROVISION_VERSION.

The combination of `--force --noop` is potentially confusing, but
currently `--noop` makes no sense without `--force`, as it will prompt

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.
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.

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`.
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.

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.

Since now we want to use production suites on Circle CI so there
is no need to set TRAVIS in env while running scripts.

Also Travis CI had rabbitmq-server installed so we had to add workaround

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.

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).
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.

it means we no longer need to ship custom apt packages at all.

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
tell it to download it in run-casper.
* ttf2woff2 transparently falls back from native code to an Emscripten
build.

This commit finishes adding end-to-end support for the install script
on Debian Buster (making it production ready). Some support for this
was already added in prior commits such as
99414e2d96.
We plan to revert the postgres hunks of this once we've built
tsearch_extras for our packagecloud archive.
Fixes#9828.
Previous cleanups (mostly the removals of Python __future__ imports)
were done in a way that introduced leading newlines. Delete leading

As a result of dropping support for trusty, we can remove our old
pattern of putting `if False` before importing the typing module,
which was essential for Python 3.4 support, but not required and maybe
harmful on newer versions.

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.

This tool can be used to update the API field of local
zuliprc files for dummy users of development server
(iago, prospero, etc) with the correct API key from database.
This tool can be run after provisioning (or similar tools) which change
the API keys in the database.
As of commit cff40c557b (#9300), these
files are no longer served directly to the browser. Disentangle them
from the static asset pipeline so we can refactor it without worrying
about them.
This has the side effect of eliminating the accidental duplication of
translation data via hash-naming in our release tarballs.

Apparently, the `chown -R` would never run if the original clone
attempt had networking errors, leading to inability to use
upgrade-zulip-from-git without manual intervention.
Previously, it didn't properly update the stamp files that determine
our caching behavior, so if one ran test-backend afterwards, nothing
would happen.
A secondary issue that this commit does not fix is that provision will
end up rerunning the whole thing.
The ids that will be used for each particular run of the test suite are
written to a unique file. Each file will then be used as a time
reference of when the suite was ran.
This change sets up the ability for a complete clean up of potentially
leaked database templates.
Tweaked by tabbott to remove these files after successful database
cleanup.
We use `git describe --tags` to get information about the number of commit since
the last major version, and the sha of the current HEAD. This is added to the
ZULIP_VERSION when a deploy is done from `git`.
Modified heavily by punchagan to:
* to use git describe instead of `git log` and `wc`
* use a separate script to run the git describe command
* write the file with version info to var/ and remove it from the repo
Fixes#4685.
API changes:
* The behaviour of Date.toLocaleTimeString() reverts to pre 8.0.0,
this only affects automated tests. Lots of other API changes but
we didn't use any of those.
* The internal sorting algorithm changed which causes one of our own
compare function to miss coverage.
Simulate isn’t enough in some cases. The error message when this
fails looks sufficiently non-alarming.

The comment explains this in more detail, but basically one previously
needed the `--from-git` option to `upgrade-zulip-stage-2` if one had
last installed/upgraded from Git, and not that option otherwise, which
would have forced us to make the OS upgrade documentation much more
complicated than it needed to be.
activate_this.py has always documented that it should be exec()ed with
locals = globals, and in virtualenv 16.0.0 it raises a NameError
otherwise.
As a simplified demonstration of the weird things that can go wrong
when locals ≠ globals:
>>> exec('a = 1; print([a])', {}, {})
[1]
>>> exec('a = 1; print([a for b in [1]])', {}, {})
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<string>", line 1, in <module>
File "<string>", line 1, in <listcomp>
NameError: name 'a' is not defined
>>> exec('a = 1; print([a for b in [1]])', {})
[1]
Top-level assignments go into locals, but from inside a new scope like
a list comprehension, they’re read out of globals, which doesn’t work.

In addition to upgrading dependencies being generally useful, this may
fix situations where yarn fails but returns a success status code in the
presence of an HTTP proxy.
Now that we have the run_as_root helper function, we don't need to
install sudo to run Zulip in production
This reverts commit a7d7d181ea.
Fixes#10036.
Few folks will be upgrading from versions of Zulip old enough to not
have virtualenv-clone, and those who are won't be able to use it due
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.
Apparently, virtualenv-clone ends up copying the success-stamp file
that we use to track whether a virtualenv was successfully
provisioned, which results in problems if we get a network error in
the pip install stage afterwards.
The comment explains our fix, but basically we just delete
success-stamp after the clone.
Fixes#11301.
On usage errors (except --help), write usage message to stderr and
exit with nonzero status.
Forbid setting the hostname and email to the example values. Those
are specifically checked for and would fail later.

Nowm unless you specify `--fill-cache`, memcached caches will not be
pre-filled after a server restart. This will be helpful when someone
is in a hurry (e.g. if the server is down right now, or if he/she
testing a configuration change in a newly setup server), it's best to
just restart without pre-filling the cache.
