Steve Howell ff3175f8a2 lightbox: Export method for testing purposes.
We weren't exercising this method in any
meaningful way during the tests, and when
do add coverage, we probably want to just
test it directly.

We also kill off stub_selector(), which was
never well-documented.

Anders Kaseorg d72423ef21 eslint: Replace empty-returns with consistent-return.
Instead of prohibiting ‘return undefined’ (#8669), we require that a
function must return an explicit value always or never.  This prevents
you from forgetting to return a value in some cases.  It will also be
important for TypeScript, which distinguishes between undefined and
void.

Hashir Sarwar c2ba3e20b7 lightbox: Remove inaccurate docstring on lightbox.open(). 2020-04-05 13:13:02 -07:00
Hashir Sarwar 34d24bfdac lightbox: Remove redundant parameter `options` from lightbox.open().
The `options` parameter is not being passed in any call
of `lightbox.open()` and it uses the same option i.e.
`lightbox_canvas` everytime which is now computed inside
`display_image()` directly.

Hashir Sarwar 74ec668e65 lightbox: Rename `original_image` to `$original_image`.

Hashir Sarwar 95869974b3 lightbox: Remove redundant conversion of `image` to jQuery object.
`image` passed to lightbox.open() is already a jQuery object,
so we don't need to convert it explicitly. Also, the parameter
is renamed from `image` to `$image`.
2020-04-05 13:13:02 -07:00
Hashir Sarwar 9ffed7afdc lightbox: Parse images' data while rendering `image-list`.
Previously, lightbox.open() was responsible for retrieving
the image data from the DOM, saving it in `asset_map` and
finally displaying the image using that data. This
implementation wasn't correct for image list at bottom of
the lightbox because the `image` parameter passed to
lightbox.open() could contain more than one instances of
the image that had to be opened.

Now, the metadata of all the images in image-list is stored
in the `asset_map` while rendering the `image-list` inside
`render_lightbox_list_images()` and `lightbox.open()` only
looks for the metadata from `asset_map`.

Fixes #14152.

Hashir Sarwar 9a6d83e731 lightbox: Use `$preview_src` as key for `asset_map`.
In case of video embeds, the previous logic used
`data-src-fullsize` or `src` as a key to look
for the metadata of video in `lightbox.open()`,
but while parsing, the key used while storing
the metadata was the video ID.

This doesn't make any sense because video's data
could never be accessed from `asset_map` and we
always needed to lookup the DOM for this.

This commit fixes this by using $img.attr('src')
as a key for `asset_map` for both, images and
videos. Since `src` is the link of preview image
in case of video embeds, it will always uniquely
determine the video ID and we won't loose
anything with the change in how videos handle
things.

Part of #14152.

Chris Heald 86faebc2e5 lightbox: Don't blow up for messages not in the message store.
This should somewhat reduce the gravity of the failure mode for cases
where the message the user clicked cannot be found (which would be a

Chris Heald c802a1393f lightbox: Cast zid to an int before looking it up in message_store.
The keys for message_store are since the recent Map migration intended
to be integer message IDs, not strings (and likely were always
intended to be integers; the failure mode may simply have shifted).

This may just be a new bug, but this max also fix #9549; certainly
we'll want to redo any investigation with this fix in place.

Fixes #9549.

Anders Kaseorg 8459185970 lightbox: Confine embedded video players to a unique origin.
This fixes a cross-site scripting vulnerability in the upcoming Inline

This commit doesn't get a CVE because the bug was present in a code
path introduced in the 2.1.x development branch, so it doesn't impact

Anders Kaseorg 28f3dfa284 js: Automatically convert var to let and const in most files.
This commit was originally automatically generated using `tools/lint
--only=eslint --fix`.  It was then modified by tabbott to contain only
changes to a set of files that are unlikely to result in significant
merge conflicts with any open pull request, excluding about 20 files.
His plan is to merge the remaining changes with more precise care,
potentially involving merging parts of conflicting pull requests
before running the `eslint --fix` operation.

Puneeth Chaganti 75635844db lightbox: Set URL in payload instead of computing from video IDs.
Lightbox previews for youtube playlists use the "current" video in the playlist

video alone, and not the playlist. This commit fixes the bug by linking to the
original URL for lightbox preview is being shown, instead of computing the URL.

Marco Burstein 11cbe2bf6a lightbox: Fix a "Pan & Zoom" causing an error with thumbnailed images.
Images on the new thumbnailing system generate an error when
"Pan & Zoom" is enabled:

    Browser Error: Lightbox for unknown message undefined
    39648: http://localhost:9991/webpack/app.js
        | Object.blueslip_error [as error]
    50743: http://localhost:9991/webpack/app.js
        | Object../static/js/lightbox.js.exports.open
    50897: http://localhost:9991/webpack/app.js
        | HTMLDivElement.

        | HTMLDivElement.dispatch
    16107: http://localhost:9991/webpack/app.js
        | HTMLDivElement.elemData.handle

To fix this, instead of using the `src` attribute as the key for
`asset_map`, which can be either the original or thumbnailed version
depending on the situation, always use the original version.

Also, create `frontend_tests/node_tests/lightbox.js` to test this
functionality.

Fix #9955.

Marco Burstein a6939a5078 lightbox: Fix lightbox not showing new thumbnails as selected.
The current code for detecting which image to add the `selected` class
to is `preview_source.match(src)`. With the new thumbnails, this no
longer works because thumbnail URLs include a `?`, which has its own
RegEx significance. To solve this, check for equality instead of using
RegExes.

Aditya Bansal 98a4e87e1d thumbor: Complete implementation of thumbnailing.
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.

Armaan Ahluwalia 6d255efe4c app: Prepare JS files for consumption by webpack.
This commit prepares the frontend code to be consumed by webpack.

It is a hack: In theory, modules should be declaring and importing the
modules they depend on and the globals they expose directly.

However, that requires significant per-module work, which we don't
really want to block moving our toolchain to webpack on.

So we expose the modules by setting window.varName = varName; as
needed in the js files.

Steve Howell 9eb3bdaf6c page load: Make initializations more explicit.
We now initialize most modules in ui_init.js, which
isn't the perfect place to do it, but at least now
we have a mostly consolidated entry point.

All the new foo.initialize() methods introduced in
this module run the same order relative to each
other as before this commit. (I did some console
logging with a hacked version of the program to
get the order right.)  They happen a bit later than
before, though.

A couple modules still have the `$(function() {`
idiom for miscellaneous reasons:

       archive - is a different bundle
       common - used elsewhere
       list_render - non-standard code style
       scroll_bar - no exports
       setup - probably special?
       socket - $(function () is nested!
       transmit - coupled to socket
       translations - i18n is a bigger problem
       ui_init - this bootstraps everything
