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.
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
significant bug on its own merit in any case).
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.
This fixes a cross-site scripting vulnerability in the upcoming Inline
URL Previews feature found by Graham Bleaney and Ibrahim Mohamed using
Pysa.
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
any Zulip release.

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.

With webpack, variables declared in each file are already file-local
(Global variables need to be explicitly exported), so these IIFEs are
no longer needed.

Ensure that the html is safe, before using it. The html is considered if it is
in an iframe with a http/https src, based on the recommendations here:
https://oembed.com/#section3
We directly embed the `iframe` html into the lightbox overlay.
Lightbox previews for youtube playlists use the "current" video in the playlist
for the preview. The open link for such previews is incorrectly set to the first
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.
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.
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.
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.
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
This is preparation for enabling an eslint indentation configuration.
90% of these changes are just fixes for indentation errors that have
snuck into the codebase over the years; the others are more
significant reformatting to make eslint happy (that are not otherwise
actually improvements).
The one area that we do not attempt to work on here is the
"switch/case" indentation.
This also amends a commit from Brock Whittaker <brock@zulipchat.com>
that merges two separate functions for YouTube videos and Vimeo videos
into a generic video recall function.
Fixes#7550.
The top and bottom sections of the lightbox overlay do not close the
lightbox when clicked. Now, this triggers the close_overlay path when a
valid non-actionable background element is clicked.
Fixes: #7500.
The lightbox "v" shortcut should not show a user's avatar,
so this limits the scope of images it can choose to ones inside
of the `.message_content` div.
When a user clicks on the `.player-container` node and the click
target is actually that (and not the YT video iFrame within), then
hide the lightbox – they likely mean to exit out of the lightbox.
This commit forces the files that create modals to create their own
modal closing function instead of creating all of them in the modals
file. These functions are then passed to the modals.close object. This
is intended to remove modals.js's dependencies on these other files.
This modifies the lightbox to only display images inside the
".message_inline_image" class, rather than all images inside the
message body, which currently includes things like the bot icon.
This fixes the styling to stay on the screen of most reasonably sized
monitors along with extending the JavaScript code to allow for the
video to be keyed to in the lightbox.
This adds an image feed that you can scroll through with hotkeys
in the lightbox.
The left and right arrow keys along with the left and right arrows
will go to the prev/next image, and clicking on an image will also
take a user to that image.
