In this commit we add new dependencies needed for running thumbor.
Also we add the script for creating the virtual environment ready
for thumbor.
Note: Thumbor will use python2 and thus have different virtualenv
dedicated to it.
Credits to @TigorC and @joshland as well for there work on this.
In this commit we add a new option which could be used to specify
python version. When 'py2' is specified, future/futures are not
removed from the requirements lock file generated.
My first version of this just replaced the repeated list of two output
files with an array variable, but I decided `"${outputs[@]}"` was too
much to ask people to understand, and the alternative of `$outputs`,
unquoted, encourages bad habits of shell programming. So just handle
one file at a time; the only at all expensive part here is `pip-compile`.
I am tempted to move this to Python, but holding back.
This makes the code a little more concise and also more uniform,
treating `future` the same in prod and in dev. The non-uniformity
looks like an oversight in 2be8a793e, one of the commits that updated
this code for the Python 3-only world.
A couple of remarks still reflected the Python 2 world; and the
"Remove the editable flag" comment was confusingly above a line
that it looks like it could be talking about, but isn't.
First, all the lines of py3_dev.txt except for mypy.txt are mv-ed to
dev.txt. Then dev_lock.txt is generated from dev.txt to be used by
py3_dev.txt. `click` is removed from moto.txt since it is already a
dependency of several libraries and will appear as an autogenerated
dependency.
I think soon we'll put the Python 3 venv at `/srv/zulip-venv` and
make `/srv/zulip-py3-venv` just an alias to that (then remove the
alias too), but for now the old name is helpful for spotting places
that need an update.
The `/srv/zulip-venv` name still appears in codepaths used by Travis
tests.
The commit is composed of: (1) distill out top-level dependencies in
common.txt, (2) add -e flag to the vcs-based packages because
pip-compile can't do without, (3) pip-compile/generate the locked files
then remove the -e flags from the lockfile, (4) pin pathlib2 to dev.txt
because it turns out it is a direct requirement of
documentation_crawler, (5) document the structure and add an automation
script (6) remove cryptography==1.9 from requirements/scrapy.txt since
cryptography is automatically added from pyopenssl (7) add sed command
to remove future/futures from the generated lock file in python3 (this
should have been automatically handled by pip-compile, so pending for
the feature from pip-compile)
Tweaked by tabbott to update PROVISION_VERSION and add a missing
`first` dependency.
