Since pushing this down to specific modules in 8ca31773c, we've
had to do bookkeeping here for every new dependency we add, unless
we add stubs for it at the same time -- which we never have.
That'd be fine if we were burning down this list and on track to
eliminate it soon, but we aren't. So, go back to a global
acknowledgement that we have a lot of untyped dependencies. The
stubs we do have will work just the same, and we can keep adding
more for whatever libraries we choose to.
Also remove the ignore_missing_imports on it, which has no effect.
That setting only does anything when mypy doesn't know where to find
the module; follow_imports only does anything when it does know.
See upstream docs:
http://mypy.readthedocs.io/en/latest/config_file.html#per-module-flags
(I confirmed with `strace -f -efile` that the place mypy is finding
the `zulip` module is in fact in the virtualenv.)
This commit adds 'resize_gif()' function which extracts each frame,
resize it and coalesces them again to form the resized GIF while
preserving the duration of the GIF. I read some stackoverflow
answers all of which were referring to BiggleZX's script
(https://gist.github.com/BigglesZX/4016539) for working with animated
GIF. I modified the script to fit to our usecase and did some manual
testing but the function was failing for some specific GIFs and was not
preserving the duration of animation. So I went ahead and read about
GIF format itself as well as PIL's `GifImagePlugin` code and came up
with this simple function which gets the worked done in a much cleaner
way. I tested this function on a number of GIF images from giphy.com
and it resized all of them correctly.
Fixes: #9945.
Various pieces of our thumbor-based thumbnailing system were already
merged; this adds the remaining pieces required for it to work:
* a THUMBOR_URL Django setting that controls whether thumbor is
enabled on the Zulip server (and if so, where thumbor is hosted).
* Replaces the overly complicated prototype cryptography logic
* Adds a /thumbnail endpoint (supported both on web and mobile) for
accessing thumbnails in messages, designed to support hosting both
external URLs as well as uploaded files (and applying Zulip's
security model for access to thumbnails of uploaded files).
* Modifies bugdown to, when THUMBOR_URL is set, render images with the
`src` attribute pointing /thumbnail (to provide a small thumbnail
for the image), along with adding a "data-original" attribute that
can be used to access the "original/full" size version of the image.
There are a few things that don't work quite yet:
* The S3 backend support is incomplete and doesn't work yet.
* The error pages for unauthorized access are ugly.
* We might want to rename data-original and /thumbnail?size=original
to use some other name, like "full", that better reflects the fact
that we're potentially not serving the original image URL.
The main purpose of this commit is to demonstrate end-to-end that
our setup for type stubs works. I picked this library more or less
arbitrarily as one where the API surface we use is tiny, so that the
stub would be extra easy to write.
This will allow us to begin to add our own stubs for external
libraries. Writing stubs can be surprisingly little work to do, and
can have high leverage in keeping our type annotations high-quality.
This commit adds a view which will be used to process login requests,
adds an AuthenticationTokenForm so that we can use TextField widget for
tokens, and activates two factor authentication code path whenever user
tries to login.
The mypy daemon only supports error and skip. Choosing error
immediately surfaces when a file excluded from the build is
being imported, so that something can be done about it.
Commit fa18913b8 preserved the fix to the actual import, but added
back the `ignore_missing_imports` line that had shielded the
erroneous import. Remove that line again.
Most of this is just asserting that the sub_dict return value from
access_stream_by_id is not None in the cases where it shouldn't be,
but additionally, we also need to pass a function into
validate_user_access_to_subscribers_helper (in this case, just `lambda:
True` works fine)
This leaves the wrapper script with very little left to do!
The main thing left is finding scripts by searching for shebang lines;
mypy itself would happily do the search for importable Python files.
This module doesn't exist, and never did; the name appears to be a
mistaken variant of the module that really does contain ZulipTestCase.
So, fix the import to use the real name.
This would never have worked at runtime, which is why it's in an
`if False:`. It's also an example of the kind of error that can be
hidden by `ignore_missing_imports`; we'd have caught the issue
immediately if we hadn't had a blanket application of that flag
in place.
