Except in:
- docs/writing-bots-guide.md, because bots are supposed to be Python 2
compatible
- puppet/zulip_ops/files/zulip-ec2-configure-interfaces, because this
script is still on python2.7
- tools/lint
- tools/linter_lib
- tools/lister.py
For the latter two, because they might be yanked away to a separate repo
for general use with other FLOSS projects.
This didn't work at all when one did a `vagrant destroy` and then
`vagrant up`, because the cache state would be preserved even though
the machine is gone.
Fixes#5981.
This should make it easier to script the installation process, and
also conveniently are the options one would want for the --certbot
option.
Significantly modified by tabbott to have a sane right interface,
include --help, and avoid printing all the `set -x` garbage before the
usage notices.
Based on #450, with commits
restructured by Rein Zustand.
Tweaks by Rein Zustand:
- Replace configure-cert with generate-self-signed-certs
- `mv scripts/lib/create-zulip-admin.sh scripts/lib/create-zulip-admin`
Deployments whose name is not in the format of a timestamp are
always included in the `recent_deployments` and are not deleted,
hence we don't need to check for them explicitly.
We were checking for whether an item in the deployments directory
represents a directory but were using its relative path which was
causing a false value to be returned for all items irrespective of
their being a directory or not if the script was invoked from some
where other than the deployments directory.
This commit re-arranges the arguments of `purge_unused_caches()`
function in order to remain consistent with other similar functions
in the library like `may_be_perform_caching()`.
This function will replace the repetitive definition of `parse_args()`
in various cache cleaning scripts. Also adds a `--verbose` argument
to the parser.
Historically, one has needed to build a release tarball in order to
use/test the Zulip installer, but you could upgrade a Zulip server
from Git. However, the only reason for that requirement was that we
didn't run `tools/update-prod-static` as part of the install script if
it's required. A good test for that case is whether we're in a Git
repository, but a better one is to check whether the prod-static
content exists in the tarball paths.
Fixes#3704.
This enforces our use of a consistent style in how we access Python
modules; "from os.path import dirname" is a particularly popular
abbreviation inconsistent with our style, and so it deserves a lint
rule.
Commit message and error text tweaked by tabbott.
Fixes#6543.
The recent rewrite of purge-old-deployments accidentally attempted to
purge the symlinks, sockets, lock, and other files in the deployment
directory.
The new version has been tested out in production successfully.
Expands `purge-old-deployments` such that now it accepts the threshold
days as argument. Also `clean-unused-caches` script is automatically
run after purging the old deployments so that the orphaned caches
gets automatically cleaned.
Fixes: #5726.
Based on the `dry_run` flag, this function either purges the list
of directories passed to them or prints a listing of the directories
it would have purged/kept_back, had the `dry_run` flag been false.
Apparently, the refactoring to make this script only run when changes
are present was buggy, in that if `apt-get update` failed, running
provision against wouldn't rerun `apt-get update`, resulting in a
broken state that requires expertise to fix. This closes that gap, by
using a stamp file to ensure we always successfully update apt before
proceeding.
It doesn't fix existing installations.
Modify `generate_sha1sum_node_modules()` such that it can calculate
the hash for a particular installation.
Tweaked by tabbott to use os.path.realpath in the setup_dir
calculation, to ensure it's consistent.
In dev always include the currently active cache in order not to break
current installation in case dependencies are updated with bumping the
provision version.
This should make it much more likely that users see this before
waiting a long time for other things to happen, since the `apt-get
dist-upgrade` step is really slow. We can't move further to the top,
since this requires `lsb_release` to be installed.
Given the path of directory containing all the caches, a list of
caches in use and threshold days, this function returns a list
of caches which can be removed safely.
This function returns a list of all the deployments directories
which are newer than some threshold number of days including the
`/root/zulip` directory if it exists.
This saves us from spending 200-250ms of CPU time importing Django
again just to log that we're running a management command. On
`scripts/restart-server`, this saves us from one thundering herd of
Django startups when all the queue workers are restarted; but there's
still the Django startup for the `manage.py` process itself for each
worker, so on a machine with e.g. 2 (virtual) cores the restart is
still painful.
This causes `upgrade-zulip-from-git`, as well as a no-option run of
`tools/build-release-tarball`, to produce a Zulip install running
Python 3, rather than Python 2. In particular this means that the
virtualenv we create, in which all application code runs, is Python 3.
One shebang line, on `zulip-ec2-configure-interfaces`, explicitly
keeps Python 2, and at least one external ops script, `wal-e`, also
still runs on Python 2. See discussion on the respective previous
commits that made those explicit. There may also be some other
third-party scripts we use, outside of this source tree and running
outside our virtualenv, that still run on Python 2.
We now call the create_large_migrations management command as part of
upgrade-zulip-stage-2 if needed, so that we can create large indexes
while the app is still up.
We can't fully support it until we fix the tsearch_extras availability
issue, but for now, this is an improvement.
Tweaked by tabbott to cover the outstanding tsearch_extras issue.
We may not necessarily be running out of /root/zulip or any particular path,
but the point this comment was really trying to make in the first place stands.
Make it more clearly and still-accurately.
Also make our dependency on `six` (for e.g. `replace-tarball-shebang`)
explicit -- we've been getting it via `python-pip`, but `python3-pip`
(on trusty) doesn't have that dependency for some reason.
Since we can use both perfer_offline=True and False in a since build
prefer_offline shouldn't be used as a cache key or it will confuse the
cleanup script. Since yarn install (if successful) should be idempotent.
This will probably be ok.
If we do wind up with a symlink lying around at `local_settings.py`,
it won't do us any harm and shouldn't be materially more confusing
than the regular file we've long had there for almost all installs.
It'll also only last as long as the current deploy. So just
let it be, and simplify the code a bit.
Also add a line to help the reader understand the remaining half of
this logic (which is essential so long as people might have pre-1.4.0
deploys lying around that they eventually get around to trying to
upgrade). The fact that it's addressed to a situation which exists
only in the past of this tree, not in its present, makes a brief
comment potentially very helpful.
This will simplify step 1 of prod-install instruction to reduce
suffering in testing/experimenting production environments.

Further tweaked by tabbott to rename the script and edit the messages.
This replaces nvm in npm-wrapper by harcoding the path the way we do
with node. The main benefit is that this saves a few hundred
milliseconds every time we invoke npm.
For performance reasons, we spawn each linter in a separate OS thread.
The downside of this is that all lints would end up in stdout without
much visual separation, resulting in confusing error log. This commit
introduce the `print_err` function, which shows which linter each line
of lint is from.
We document the `deployment.git_repo_url` setting in `/etc/zulip/zulip.conf`
to control where this script fetches from, and don't say that it's
only read on the first such upgrade and cached thereafter. The documented
behavior seems like the right behavior. So use the currently configured
URL every time, by writing it anew into the config of our cache repo.
Basically we just seperate out the sha1sum generation for the
node modules so that it can be reused later for cache clearance
logic. This is achieved by adding a function which returns the
sha1sum based HEX digest.
When we added support for automatically adding new secrets in
generate_secrets.py, we failed to account for the possibility that a
human editor might have let the secrets file without a trailing
newline.
We address this by adding a leading newline before our new secret.
Fixes#5209.
The Zulip email mirror script called by postfix had performance/load
issues, because it spent so much time on startup/import due to use of
the Zulip virtualenv.
The script was rewritten using pure python (no Django) to improve
performance.
The install script was failing on 2nd+ attempts if the first attempt
was interrupted.
This failure happened because zulip-venv already existed at
`current_venv_path`. Changing the `ln` command's flags from `-s` to
`-nsf` should make this part of the script idempotent.
Now, generate_secrets.py will never overwrite existing secrets. In
addition to being a safer model in generate, this fixes 2 significant
issues:
(1) It makes it much easier to preserve secrets like Oauth tokens in a
development environment (previously, provision would destroy them).
(2) It makes it possible to automatically add new secrets as part of
the upgrade process. In particular, this is useful for the
zulip_org_id settings.
Fixes#4797.
This fixes a significant performance issue with LaTeX rendering (and
other things that invoked node) where starting up node took a few
hundred milliseconds due to nvm initialization.
Tweaked by tabbott to avoid copying the node binary itself, instead
using a tiny wrapper script.
This is important primarily because it's possible a future version of
node will expect to find libraries/dependencies/etc. installed via NVM
at some path related to the path of the node binary itself, and that's
more guaranteed with this new model.
Fixes#4618.
Also puts them into a processing queue, though the queue processor
does nothing.
Rewritten by tabbott to avoid unnecessary database queries in
do_send_messages.
This fixes a performance problem where we were previously starting up
a full Django process (~0.7s even on a fast machine) every time a new
email came in, potentially allowing users to accidentally DoS a Zulip
server. Now, we just post over HTTPS, allowing the existing thread
pool support to do its job.
- Add script wrapper to communicate postfix pipe with django web server
over HTTP(S). It uses shared_secret authentication mode.
- Add django view to process messages from email mirror server.
- Clean management command `email-mirror`. Left just functional
for cron email processing.
- Add routes for new tornado view.
- Change pipe script in master process postfix config template
based on updated script.
- Add tests.
Tweaked by tabbott to adjust the directory and set better defaults.
Fixes#2421.
Follow-on from #2373/ PR https://github.com/zulip/zulip/pull/4316, to set an
appropriate umask also when upgrading so files have appropriate permissions.
I've tested this by starting from a clean install, deleting /srv/* so new
files are downloaded, and then doing an upgrade. It worked starting with both
a current version from master and an older release installed with a less
restrictive umask and then the umask changed.
Fixes#2373.
- Add new 'missedmessage_email_senders' queue for sending missed messages emails.
- Add the new worker to process 'missedmessage_email_senders' queue.
- Split aggregation missed messages and sending missed messages email
to separate queue workers.
- Adapt tests for sending missed emails to the new logic.
Fixes#2607
* Now queue_workers.py sorts queue names and prints them on their own
line. Previously it's output was nondeterministic.
* Simplified grep strategy for removing the "test" worker.
This list was likely to end up out of date quickly, since it wasn't
documented that you need to update it when adding a queue. The best
solution is to just not require it to be updated.
Now that we no longer use node_modules at all in production (it's only
used to generate static assets), we don't include `node_modules` in
the production tarballs, and thus we shouldn't attempt to copy
`node_modules` out of the production tarballs when installing.
Fixes a regression introduced in
d71f2e7b9b.
This saves about a minute of downtime when using
upgrade-zulip-from-git in the default configuration.
It should also save several seconds of downtime when upgrading to a
production release tarball as well.
This indirectly causes the RabbitMQ node name for new Zulip
installations to default to zulip@localhost, which would eliminate the
persistent problems we have had
Fixes#194, #465, #1375, #1751.

This adds a dependency on the realpath package on trusty; we could try
to remove it if needed, but given that realpath is included in
coreutils on Xenial (and presumably anything else modern), I think
it's reasonable to add it.
Fixes#1797.
Previously, success_stamp was touched whenever we used a particular
node_modules version; it makes more sense to only touch it when the
node_modules directory has actually changed.
get_package_names did not correctly strip the GitHub URLs from package
names, resulting in the "package names" for our dependencies installed
from Git being tracked with the complete sha1sum included in the name.
This meant that upgrading our virtualenvs incorrectly ended up
resorting to creating an entirely new virtualenv whenever we changed a
dependency that had previously been installed from GitHub URLs.
Now that we're no longer actively debugging this tool, there's no need
to have it print everything it's doing.
This will make `test-backend` a lot nicer to use.
generate-secrets.py now requires --development for development environment
setup or --production for production environment setup (and one of these
options is mandatory).
This solves the problem that it was somewhat easy to accidentally run
generate-secrets.py without the `-d` option while doing manual development
environment setup.
Fixes: #1911.
This is a first pass at building a framework for collecting various
stats about realms, users, streams, etc. Includes:
* New analytics tables for storing counts data
* Raw SQL queries for pulling data from zerver/models.py tables
* Aggregation functions for aggregating hourly stats into daily stats, and
aggregating user/stream level stats into realm level stats
* A management command for pulling the data
Note that counts.py was added to the linter exclude list due to errors
around %%s.
NVM takes a specific node version and installs the node package and
a corresponding compatible npm package.
We use it in a somewhat hackish way to install node/npm globally with
a pinned version, since that's how we actually want to consume node in
our development environment.
Other details:
- Travis CI now is configured to use the version of node installed by
provision; the easiest way to do this was to sabotage the existing node
installation.
- jsdom is upgraded to a current version, which both requires recent
node and also is required for the tests to pass with recent node.
This fixes running the node tests on Xenial.
Fixes#1498.
[tweaked by tabbott]
This adds a new system for copying packages from old virtualenvs that
are sufficiently similar to the new virtualenv required.
In practice, this results in a huge performance improvement for
re-provisioning Zulip development environments when the requirements
files have changed (which is the dominant performance problem with
provision today).
Fixes: #1507.
Between releases 1.3.13 and 1.4.0, local_settings.py was renamed to
prod_settings.py. The upgrade scripts were adjusted to reflect this name
change. But because the first part of the upgrade script is run with the
currently installed version's code, the symlink to /etc/zulip/settings.py is
created with the old name. This was causing upgrade-zulip-stage-2 to fail.
Now upgrade-zulip-stage-2 creates the symlink at zproject/prod_settings.py
if it doesn't already exist.
Fixes#1731.
