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.
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.
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.
* 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

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.
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.
