This commit renames various source requirements files like `dev.txt`,
`mypy.txt` etc to `dev.in`, `mypy.in` etc and various locked requirements
files like `dev_lock.txt`, `mypy_lock.txt` etc to `dev.txt`, `mypy.txt`
etc. This will help in emphasizing to the user that *.in are actually
input to `update-locked-requirements` tool which should be run after
updating any of these.
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.
