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.
- Add stamp file creation for the failed templates compilation.
- Add error response to `home` route if stamp file exists. It appears
just for the development environment.
- Add jinja2 template for failed handlebars templates compilation error.
Fixes#3650.
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.
Previously, we didn't install/pin our own node.js version, and thus
had this wrapper script to manage it. Now that install our own node
via nvm, there's no reason we still need this.
Fixes#2409.
The "forever" option causes the tool to continue looking for
template changes and, when they happen, to recompile them.
