This seems to be a common enough pitfall to justify
a bit of extra handling. Example output:

Before this change, the way we loaded
webpack for various tools was brittle.
First, I addressed test-api and test-help-documentation.
These tools used to be unable to run standalone on a
clean provision, because they were (indirectly)
calling tools/webpack without the `--test` option.
The problem was a bit obscure, since running things
like `./tools/test-backend` or `./tools/test-all` in
your workflow would create `./var/webpack-stats-test.json`
for the broken tools (and then they would work).
The tools themselves weren't broken; they were the
only relying on the common `test_server_running` helper.
And even that helper wasn't broken; it was just that
`run-dev.py` wasn't respecting the `--test` option.
So I made it so that `./tools/run-dev` passes in `--test` to
`./tools/webpack`.
To confuse matters even more, for some reason Casper
uses `./webpack-stats-production.json` via various
hacks for its webpack configuration, so when I fixed
the other tests, it broke Casper.
Here is the Casper-related hack in zproject/test_settings.py,
which was in place before my change and remains
after it:
if CASPER_TESTS:
WEBPACK_FILE = 'webpack-stats-production.json'
else:
WEBPACK_FILE = os.path.join('var', 'webpack-stats-test.json')
I added similar logic in tools/webpack:
if "CASPER_TESTS" in os.environ:
build_for_prod_or_casper(args.quiet)
I also made the helper functions in `./tools/webpack` have
nicer names.
So, now tools should all be able to run standalone and not
rely on previous tools creating webpack stats files for
them and leaving them in the file system. That's good.
Things are still a bit janky, though. It's not completely
clear to me why `test-js-with-casper` should work off of
a different webpack configuration than the other tests.
For now most of the jankiness is around Casper, and we have
hacks in two different places, `zproject/test_settings.py` and
`tools/webpack` to force it to use the production stats
file instead of the "test" one, even though Casper uses
test-like settings for other things like which database
you're using.
This changes run-dev.py to ensure that we have in fact compiled
handlebars templates before running webpack, which is the right model.
Future work will likely include running the handlebars compiler from
webpack, and thus eliminating this extra process.
This commit adds a --quiet argument to tools/webpack which removes
the verbose output from webpack and replaces it with showing only
errors. It also makes tools/run-dev --tests use this argument while
running webpack for testing.
Tweaked by tabbott to clean up the code a bit.
Webpack dev server by default does host checking for requests. so
in dev enviorment if the the request came for zulipdev.com it would not
send js files which caused dev envoirment to not work.
For now, this does nothing in a production environment, but it should
simplify the process of doing testing on the Thumbor implementation,
by integrating a lot of dependency management logic.
This reverts commit 66261f1cc. See parent commit for reason; here,
provision worked but `tools/run-dev.py` would give errors.
We need to figure out a test that reproduces these issues, then make a
version of these changes that keeps that test working, before we
re-merge them.
This method was new in Tornado 4.0. It saves us from having to get
the time ourselves and do the arithmetic -- which not only makes the
code a bit shorter, but also easier to get right. Tornado docs (see
http://www.tornadoweb.org/en/stable/ioloop.html) say we should have
been getting the time from `ioloop.time()` rather than hardcoding
`time.time()`, because the loop could e.g. be running on the
`time.monotonic()` clock.
Tweaked by tabbott to not remove it from lister.py, linter_lib, and
friends, since those are intended to support both Python 2 and 3
(we're planning to extract them from the repository).
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.
This allow the webbpack dev server to properly reload JavaScript modules
while running in dev without restarting the server. We need to connect
to webpack-dev-server directly because SockJS doesn't support more than
one connection on the same host/port.
This hack saved a lot of time debugging weird issues back in 2016, but
it's no longer needed.
Anyone rebasing a branch from 2016 will need to provision afterwards
regardless, which will fix this issue automatically, and more
importantly, these changes were made obsolete when we moved to the
cached `node_modules` model.
This fixes an issue where if you saved a Python file (even just
changing whitespace) while casper tests were running, the Tornado
server being used would restart, triggering a confusing error like
this:
ReferenceError: Can't find variable: $
Traceback:
undefined:2
:4
Suite explicitly interrupted without any message given.
This helps make the Zulip development environment somewhat more robust
to new contributors, since it will give them a nice warning if they
try running any of our development tools outside the Zulip virtualenv.
Fixes#3468.
- Add pid file of development processes group, which allows to
manage development processes group with os utils. Also it allows to
kill subprocesses when parent process was closed incorrectly.
- Add tool 'stop_dev_server' to stop development server by pid file.
Fixes#1547
Previously, we got the following as a part of the output when running
`tools/run-dev.py` without provisioning:
It looks like you checked out a branch that has added
dependencies beyond what you last provisioned. Your tests
are likely to fail until you add dependencies by provisioning.
which is a bit confusing.
- Add rewriting 'X-REAL-IP' header for each request through dev
proxy server.
- Change webpack configuration ip to 0.0.0.0 to fix socket.io build
for launching remote dev server.
When we migrated run-dev.py from Twisted to Tornado a few weeks ago,
the --interface argument wasn't properly ported and thus was ignored.
This restores the original functionality of defaulting to only
listening on localhost.
Ideally, we'd replace the vagrant/zulipdev user check with something
that just checks whether a special file that is created by the
Vagrant/remote-dev-vm creation process exists; that would be more
robust.
(Why is -u needed at all? I’m not sure, but test-run-dev spins forever
“Polling run-dev...” without it.)
