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 in travis we don't have root access so we used to add different

now of no use.

an awkward mechanism to hide its output; we can just print it out like
a normal program.

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.

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.

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.

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
attempt had networking errors, leading to inability to use

A secondary issue that this commit does not fix is that provision will

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.

Instead, manually activate it in the one place where this
functionality was used (tools/lib/provision.py). This way we avoid
trying to activate the Python 2 thumbor virtualenv from Python 3.

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.
Fixes: #10900.

This is a common bug that users might be tempated to introduce.
And also fix two instances of this bug that were present in our
codebase, including an important one in our upgrade code path.
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.
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.
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:

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

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.

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.
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.
The is_private flag is intended to be set if recipient type is
'private'(1) or 'huddle'(3), otherwise i.e if it is 'stream'(2), it
should be unset.
This commit adds a database index for the is_private flag (which we'll
need to use it). That index is used to reset the flag if it was
already set. The already set flags were due to a previous removal of
is_me_message flag for which the values were not cleared out.
For now, the is_private flag is always 0 since the really hard part of
this migration is clearing the unspecified previous state; future
commits will fully implement it actually doing something.
History: Migration rewritten significantly by tabbott to ensure it
runs in only 3 minutes on chat.zulip.org. A key detail in making that
work was to ensure that we use the new index for the queries to find
rows to update (which currently requires the `order_by` and `limit`
clauses).
This package is important in order to avoid scary-looking errors
whenever we upgrade the dependencies in thumbor.txt (where
virtualenv-clone isn't installed in the venv, and then gets installed
by the code we just added a TODO comment to.
Apparently, perl at least expects LANG, LANGUAGE, and LC_ALL to be
consistent, and thus apt spits out a bunch of warnings if these are
different. So if we're forcing LC_ALL in these installer/upgrade
script blocks, we should force the rest too.
I believe this fixes the remaining locale part of #9946.
--agree-tos is useful for the Docker environment, where we won't have
an interactive shell present for agreeing to the ToS.
--deploy-hook is also useful for the Docker environment; it makes it
possible to customize what deploy hook (if any) we pass into the
underlying cerbot command.
This migrates Zulip to use a dramatically better set of names and
aliases for our emoji set, defined in emoji_names.py (which is in turn
manually generated from our hand-curated CSV file).
This should significantly improve the experience of using Zulip's
emoji picker and emoji typeahead for finding what one is looking for.
We were already correctly including libssl-dev in Zulip's dependencies
in development environment provisioning, but (at least now) it's
needed to build certain Python packages like pycurl when building a
Zulip virtualenv in production. I haven't investigated why we didn't
need this on Ubuntu, but one possible reason would be that some other
library in our dependencies list happens to depend on it on Ubuntu.
We fix this by moving the dependency over to the shared
VENV_DEPENDENCIES list.
Fixes part of #9946.
Apparently, at least some Debian stretch systems don't have an
/etc/lsb-release, so the optimization that we did in
5d39a0f0fc broke our installer on
Debian.
We fix this, by falling back to calling the lsb_release command on
systems that don't have a faster way to do it.
Fixes part of #9946.
This commits adds the necessary puppet configuration and
installer/upgrade code for installing and managing the thumbor service
in production. This configuration is gated by the 'thumbor.pp'
manifest being enabled (which is not yet the default), and so this
commit should have no effect in a default Zulip production environment
(or in the long term, in any Zulip production server that isn't using
thumbor).
Credit for this effort is shared by @TigorC (who initiated the work on
this project), @joshland (who did a great deal of work on this and got
it working during PyCon 2017) and @adnrs96, who completed the work.
The only changes visible at the AST level, checked using
https://github.com/asottile/astpretty, are
zerver/lib/test_fixtures.py:
'\x1b\\[(1|0)m' ↦ '\\x1b\\[(1|0)m'
'\\[[X| ]\\] (\\d+_.+)\n' ↦ '\\[[X| ]\\] (\\d+_.+)\\n'
which is fine because re treats '\\x1b' and '\\n' the same way as
'\x1b' and '\n'.

This saves about 400ms when running clean-unused-caches, basically by
calling its sub-rountines by import (rather than
`subprocess.check_call()`). The performance optimization seems well worth it.
Fixes#9766.
This file looks like it's producing some kind of compilation of the
mobile strings, that the mobile app will somehow end up using --
especially as it refers to its output as a "resource file". In
reality, it compiles statistics to be included in the language-picker
UI in the web app. Give appropriate names to the identifiers so it's
less confusing.
This improves the performance of these operations, by saving a ~50ms
Python process startup. While not a major performance improvement, it
seems worth it, given how often these commands get run.
Fixes#9571.
On newer distros like Xenial, Stretch, etc., we were incorrectly not
installing the Python 3 version of the virtualenv package. This was
accidentally working because most base images with Python already have
this package too, but this was failing to install the right
dependencies in our Docker builds, requiring unnecessary manual code.
We fixed this some time ago for provision.py, but not for production.
The docker installer configuration incorrectly had has_appserver set
to 0; this meant that (A) the docker-zulip code needed to copy the
block of code in the installer for the `has_appserver` case into the
Dockerfile (unnecessarily), and (B) one couldn't use `install` from a
Git ref (because the static asset compiler didn't end up in the right
place).
It appears that docker-zulip tried to set this flag in their `install`
command line, but the construction inside `install` meant that didn't
work.
This fixes adding the Ubuntu repositories for Debian, as well as makes
sure that we install the debian-archive-keyring package on Debian,
which is only priority important (and thus might be missing).
It wasn't obvious reading this message that you can perfectly well
bring your own SSL/TLS certificate; unless you read quite a bit
between the lines where we say "could not find", or followed the link
to the detailed docs, the message sounded like you had to either use
--certbot or --self-signed-cert.
So, explicitly mention the BYO option. Because the "complete chain"
requirement is a bit tricky, don't try to give instructions for it
in this message; just refer the reader to the docs.
Also, drop the logic to identify which of the files is missing; it
certainly makes the code more complex, and I think even the error
message is actually clearer when it just gives the complete list of
required files -- it's much more likely that the reader doesn't know
what's required than that they do and have missed one, and even then
it's easy for them to look for themselves.
This fixes a bug where provision was failing since our most recent
upgrade to yarn/nvm/node.
It turns out my original fix was the correct fix, but to the wrong
third-party tool: nvm, not yarn, was the offender.
Apparently, new versions of yarn use the HOME environment variable to
figure out where to access their configuration, and sudo apparently
doesn't clear that variable, so install-node was being run with HOME
set to something under /home/vagrant (e.g.).
Fix this by just setting that environment variable correctly.
This replaces 250a036ff8, which
misdiagnosed the issue.
It appears that some change in yarn's versioning system means that
installing yarn itself ends up chowning its config directory
incorrectly to be owned by root, preventing `yarn install` from
working later.
node -> v8.9.4
yarn -> 1.5.1
nvm -> 0.33.8
Also updates a test in timerender.js which depends on time
provided by node which is now changed in newer release.
Some changes have been made in circeci script, we just create ~/.config
directory and chown it to circleci user so installing new version of yarn
does not cause any ci failure on circleci during provision.
This is the analog of 7b2c9223e7 for the
emoji cache; the only difference is that the existing code was working
correctly. It's still worth changing for improved robustness.
We saw issues with /srv/zulip_npm_cache being cleaned incorrectly by
this tool in production (more correctly, we noticed broken symlinks to
those directories, even from the current deployment). Print-debugging
showed that indeed older deployments were being ignored, because the
logic for `get_caches_in_use` was totally broken (this was sorta
masked because we also keep the last week's deployments).
The specific bug here turned out to be that we weren't passing the
`production` argument to generate_sha1sum_node_modules, but the
broader problem is that this logic isn't robust to changes in the
hashing algorithm.
Fix this by replacing the broken logic for trying to compute the
correct hash for that deployment with just checking the symlink inside
the deployment to let it self-report.
We can't easily do this same change for clean-venv-cache, because we
use multiple virtualenvs there. But a similar change could be useful
for the emoji cache as well.
Fixes#8116.
This is apparently installed by the perl package; I hadn't even known
it existed. We of course want to use the sha1sum command from
coreutils.
Fixes#8836.
This commit switches our emoji infrastructure to use 256 color indexed
64px spritesheets. Earlier we were using non-indexed 32px spritesheets
which were blurry on high dpi displays. These indexed spritesheets not
only provide a crispier display but are also smaller in size.
This commit also removes the `emoji-datasource` package as a dependency
as all the data is now sourced from individual datasource packages.
Fixes: #7862.
The installation isn't really complete here, and wasn't even when this
was the only success case; the instructions we're giving are for the
next step in the installation.
These instructions don't say what to do in an actual use case for this
option, but decent instructions there will require having a concrete
use case in front of us and designing the flow for it. At this stage,
just say where we are in the normal flow, and an admin who's chosen to
go off that flow can figure out how they want to vary it from there.
This flips the experimental `--express` option to be the default.
We retain the old behavior, where the script exits before
`initialize-database`, as an option `--no-init-db`; it might be useful
in e.g. a migration scenario (from a Zulip install elsewhere, or
another chat system) where the admin wants to set up the database
separately.
The install instructions are adjusted to match, getting shorter by two
steps and a bunch of words. I think this opens up opportunities to
refactor the text to simplify things further, too, but leaving that
for another commit.
Also tweak the "production" test suite to match.
Kind of unfortunate because the `sudo` interface for running a command
is objectively better -- a list of arguments, rather than a string to
be re-parsed by the shell. But some bare-bones machine images lack
`sudo`, so this makes things a bit more portable.
