Forbid setting the hostname and email to the example values. Those

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.

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

The original code was actually broken, in that it checked the wrong

By far the dominant cause of errors when installing apt packages is

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

'\\[[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.
We do the following here:
* Remove libjasper-dev from THUMBOR_VENV_DEPENDENCIES.
Reason: This dependancy wasn't really needed by us for using
thumbor. It was a dependancy for using open-cv as Imaging Engine
in thumbor but we use PIL (Pillow now) as Imaging Engine.
* Add zlib1g-dev, libfreetype6-dev to THUMBOR_VENV_DEPENDENCIES.
Reason: These are dependancies of Pillow which are required for it
Pillow to function. Since we use Pillow in thumbor as Imaging Engine
we need these. Stuff before this didn't break because we also use
Pillow in development Environment and have these dependancies
installed from VENV_DEPENDENCIES as well.
We'll make this the normal behavior soon, once we're satisfied with
our arrangements for sending the admin straight to realm creation and
using the app without configuring email. The instructions in the docs
will also have to change accordingly, of course.
This causes us to give an error if you pass the installer any
positional arguments, e.g. with `--`. There's no reason you'd want
to do this, but I accidentally did it by passing an extra `--` to
the `test-install/install` wrapper and spent a few minutes on
confused debugging.
This gives us just one way of adopting a self-signed cert, rather than
one script which would generate a new one and an option to another
which would symlink to the system's snakeoil cert. Now those two
codepaths converge, and do the same thing.
The small advantage of generating our own over the alternative is that
it lets us set the name in the cert to EXTERNAL_HOST, rather than the
system's hostname as embedded in the system snakeoil certs. Not a big
deal, but might make things go slightly smoother if some browsers are
lenient (in a way that they probably shouldn't be.)
Before this fix, the installer has an extremely annoying bug where
when run inside a container with `lxc-attach`, when the installer
finishes, the `lxc-attach` just hangs and doesn't respond even to
C-c or C-z. The only way to get the terminal back is to root around
from some other terminal to find the PID and kill it; then run
something like `stty sane` to fix the messed-up terminal settings
left behind.
After bisecting pieces of the install script to locate which step
was causing the issue, it comes down to the `service camo restart`.
The comment here indicates that we knew about an annoying bug here
years ago, and just swept it under the rug by skipping this step
when in Travis. >_<
The issue can be reproduced by running simply `service camo restart`
under `lxc-attach` instead of the installer; or `service camo start`,
following a `service camo stop`. If `lxc-attach` is used to get an
interactive shell, these commands appear to work fine; but then when
that shell exits, the same hang appears. So, when we start camo
we're evidently leaving some kind of mess that entangles the daemon
with our shell.
Looking at the camo initscript where it starts the daemon, there's
not much code, and one flag jumps out as suspicious:
start-stop-daemon --start --quiet --pidfile $PIDFILE -bm \
--exec $DAEMON --no-close -c nobody --test > /dev/null 2>&1 \
|| return 1
start-stop-daemon --start --quiet --pidfile $PIDFILE -bm \
--no-close -c nobody --exec $DAEMON -- \
$DAEMON_ARGS >> /var/log/camo/camo.log 2>&1 \
|| return 2
What does `--no-close` do?
-C, --no-close
Do not close any file descriptor when forcing the daemon
into the background (since version 1.16.5). Used for
debugging purposes to see the process output, or to
redirect file descriptors to log the process output.
And in fact, looking in /proc/PID/fd while a hang is happening finds
that fd 0 on the camo daemon process, aka stdin, is connected to our
terminal.
So, stop that by denying the initscript our stdin in the first place.
This fixes the problem.
The Debian maintainer turns out to be "Zulip Debian Packaging Team",
at debian@zulip.com; so this package and its bugs are basically ours.
This provides a major simplification for non-production installs,
including our own testing (it's already in both the test-install
harness script and the "production" test suite) as well as potential
admins evaluating Zulip.
Ultimately this should probably be the default behavior, with perhaps
something shown to admins on the web as a reminder and link to help on
installing a better certificate. For now, pending working through
that, just get the behavior in and leave it opt-in.
The third-party `install-yarn.sh` script uses `curl`, and we invoke it
in `install-node`. So we need to install it as a dependency.
We've mostly gotten away with this because it's common for `curl` to
already be installed; but it isn't always.
Apparently, this was checking the wrong path in Travis CI, and thus
never actually running (meaning we'd accumulate every `node_modules`
directory ever in the Travis caches, which in turn resulted in very
slow builds).
This updates commit 11ab545f3 "install: Set the locale ..."
to be somewhat cleaner, and to explain more in the commit message.
In some environments, either pip itself fails or some packages fail to
install, and setting the locale to en_US.UTF-8 resolves the issue.
We heard reports of this kind of behavior with at least two different
sets of symptoms, with 1.7.0 or its release candidates:
https://chat.zulip.org/#narrow/stream/general/subject/Trusty.201.2E7.20Upgrade/near/302214https://chat.zulip.org/#narrow/stream/production.20help/subject/1.2E6.20to.201.2E7/near/306250
In all reported cases, commit 11ab545f3 or equivalent fixed the issue.
Setting LC_CTYPE is redundant when also setting LC_ALL, because LC_ALL
overrides all `LC_*` environment variables; so skip that. Also move
the line in `install` to a more appropriate spot, and adjust the
comments.
