The channel/<ucid>/playlists page was vulnerable to Cross Site Scripting
(XSS), because the different URL parameters were inserted as-is in the URL
meant for instance switching.
This vulnerability could allow an attacker to inject malicious Javascript
in the page by tricking the user to click on a crafted link.
Bug introduced in commit 66e7285108
("Only use /redirect when automatically redirecting").
Thanks to Jack (@testa:cthd.icu on Matrix, @cysea on github) for responsibly
reporting this issue!
'.to_i64?' instead of '.to_i64' returns nil rather than raising
an exception when it's done on an empty string.
In some rare cases, rating can be equal to 5. In this case, the
value of player_response[videoDetails][averageRating] is an
Int and not a Float.
* on watch page and video cards (search results, playlists, etc...)
* on /feed/playlists
* in search filters (not normalized in order to avoid collisions with
an existing PR that reworks the search filters)
given the variables available in this function's context, 'author' and 'ucid'
provide the same data 'self.author' and 'self.ucid', respectively.
Given that fact, the variable `auto_generated` has no impact on the logic of
this function, and hence can be safely removed. this greatly simplifies the
code and makes it perfectly compatible with crystal's calling convention for
'#to_xml' methods.
Changes in the aforementioned PR lead to change the behavior
of some old code.
The data type of the parameters aren't explicit enough, which
makes the compiler use the wrong method because of type infering.
* Fix for #2488 - parse contents of search results of type=Category (returned on first page for universal (type=all) queries instead of returning an error.
* Moved content array walker to Category#to_json
As requested by reviewer this change moves the content array walker from the API endpoint to the Category class.
* Update src/invidious/helpers/serialized_yt_data.cr

* Add debug/trace logging to extract_items
* Handle invalid timestamps for livestreams extraction
* Make use of author_fallback in playlist extractor
* Don't use extract_text for video length extraction
The extract_text function attempts to extract from both the simpleText and
the runs route. This is typically what we'd want for text extraction as
it could appear in both locations. However, while this still holds true,
the thumbnailOverlayTimeStatusRenderer writes a numerical length (when
present on the video) to the simpleText route and uses runs for a
text overlay like "LIVE" or "PREMIERE".
Therefore, when a video has a text overlay instead of a numerical one,
Invidious still passes it onto decode_length_seconds, which obviously
raises since it cannot be converted into integers.
In the future, if more routes requires one text route over the other, we
should go ahead and add an argument to extract_text itself. Though for
now, this is sufficient.
* Handle unsupported "special" categories
- Add extract_text to simplify extraction of InnerTube texts
- Add helper extractor methods to reduce repetition in parsing InnerTube
- Change [] more than 2 blocks long to use #dig or #dig?
- Remove useless ?.try blocks for items that always exists
- Add (some) documentation to VideoRendererParser

This commit adds a new parser for YT's shelfRenderers which are
typically used to denote different categories.The code for featured
channels parsing has also been moved to use the new parser but some
additional refactoring are needed there.
The ContinuationExtractor has also been improved and is now capable of
extraction continuation data that is packaged under
"appendContinuationItemsAction"
In additional this commit adds some useful helper functions to extract
the current selected tab the continuation token. This is to mainly
reduce code size and repetition.

(cherry picked from commit 8000d538db)
This commit completely rewrites the extract_item and extract_items
function. Before this commit these two function were an unreadable
mess. The extract_item function was a lengthy if-elsif chain
while the extract_items function contained an incomprehensible
mess of .try, else and ||.
With this commit both of these functions have been pulled into a
separate file with the internal logic being moved to a few classes.
This significantly reduces the size of these two methods, enhances
readability and makes adding new extraction/parse rules much simpler.
See diff for details.

(cherry picked from commit a027fbf7af)
Upstream requires at least two additional sources. Whereas Invidious needs it to be
able to display a single additional source for normal (dashless)
qualites. Aka medium and hd720.
Video mimetype may contain code information between double quotes.
If not properly escaped, it breaks the browser's parser. E.g:
```
type="video/mp4; codecs=" avc1.64001f,="" mp4a.40.2""=""
```
Thank Robin for catching this!
* Extract feed routes from invidious.cr
* Removes the deprecated route for /feed/top
* Deprecate /view_all_playlist & use /feed/playlists
* Move feed views into their own directory
* Add haltf method to halt current route context
* Change status_code + return blocks to use haltf
* Set appropriate response headers for RSS routes
- Auth (excluding notifications*) APIs
- Mixes
*Notifications currently require the "connection_channel" channel
for talking with the notifications job. Unfortunately, we cannot
access that within the route modules yet.
* use the new youtube api for comments
* remove PG_DB & action parameter + allow force region
* support new comments data with onResponseReceivedEndpoints
* Extract primary channel routes from invidious.cr
Also removes timedtext_video stub since all it does is redirect to the
homepage. However, Invidious's 404 handler already does this.

As the template for the channel about page doesn't exist yet, the
behavior for the /channel/:ucid/about endpoint has been changed to be
the same as what's currently present on Invidious
(cherry picked from commit 8fad19d805)
* Manually extract brand_redirect from 1b569bbc99
This commit manually extracts the brand_redirect function from the
commit mentioned.
However, the redirect to the `.../about` endpoint is removed due to the
fact that it doesn't exist yet.
This commit is also mainly just a bridge for the next few cherry picks from
\#2215
* Update brand_redirect to use youtubei resolve_url
(cherry picked from commit 53335fe7cf)
* Add additional channel endpoints to brand_redirect
(cherry picked from commit 8fc6f3add6)
* Add separate handler for /profile endpoint
* Add /channel/:ucid/home route
* Document all channel brand_urls
* Move Crystal stdlib classes overrides to a separate file
* Document known crystal overrides
* Update crystal overrides for HTTP::Client socket
* Update shard.yml to restrict crystal versions
* Fix compilation error in Crystal 1.1.x (See
https://github.com/crystal-lang/crystal/issues/10965
for more details about this issue).
The private `_post_json` method of the YoutubeAPI requires a ClientConfig
as the third parameter. This was passed in all Youtube API methods except the
`#resolve_url` method.
* Put youtube API functions under the YoutubeAPI namespace
* Implement the following endpoints:
- `next`
- `player`
- `resolve_url`
* Allow a ClientConfig to be passed to YoutubeAPI endpoint handlers.
* Add constants for many new clients
* Fix documentation of YoutubeAPI.browse(): Comments and search
result aren't returned by the browse() endpoint but by the next()
and search() endpoints, respectively.
* Accept gzip compressed data, to help save on bandwidth
* Add debug/trace logging
* Other minor fixes
Fixes:
* Sanitize user-provided content in HTML (Fixes#2193)
* Fix encoding of search query in prev/next pages (Fixes#2229)
* Fix some issues introduced with #2196:
- Fix alignment of all <h3> elements (Move the inline style from the parent to the <h3> element)
- Add missing comma on 'dir' HTML attribute (Typo introduced by PR #2196)
Code cleaning:
* Remove unnecessary 'each_sclice' + 'each' double loop in ECR files
* Clean the player's <source> list generation code (in player.ecr)
Related to #1416, it doesn't really fix the real error, but instead mutes the exception message.
Like explained in #1416, this "exception Error" while flushing the client data doesn't harm the client-server connection. However, this exception message continuously spams the logs and makes debugging and error finding really difficult.
Cherry picked from ui overhaul branch with a few modifications:
- channel folder is renamed to channels
- parsing for channel home and featured channels are removed due to
lack of infrastructure from other commits
(cherry picked from commit 44d18b8e14)
i was injecting custom css into the site that made the avatars round, and noticed comment avatars looked a little odd
i opened dev tools and siffed through the html, and noticed that the image was being padded,
when it would look nicer if the element used margin instead of padding
with padding:
https://imgur.com/c0pB37e
with proposed changes (margin instead of padding):
https://imgur.com/iKmBzEi
The behavior was as follow: on Right-To-Left text (e.g Arabic) that is wrapped
(because it's too long to fit on one line), the second row and following rows
may or may not be right aligned (as RTL text should be). Opening the devtools
fixes that alignement, as consistently as closing the devtool breaks it.
This problem seems to arrive only in the following configurations (link nested
in a paragraph, both of which may or may not have the dir= attribute):
* `<p><a href="some_link">RTL_TEXT</a></p>`
* `<p><a href="some_link" dir="auto">RTL_TEXT</a></p>`
* `<p dir="auto"><a href="some_link">RTL_TEXT</a></p>`
with the following CSS:
```
p {
unicode-bidi: plaintext;
text-align: start;
}
```
Changing the HTML to the following configuration (a paragraph with the dir=
attribute, nested in a link) seems to fix it:
`<a href="some_link"><p dir="auto">RTL_TEXT</p></a>`
This will prevent, on large pages, the LTR and RTL text to be
far away, on each side of the page. This could happen on channel
and playlists descriptions, when the page is displayed on a large
screen.
* Remove percent-encoding of the search query when calling youtube API, as it
breaks UTF-8
* Empty search redirects to /search, not /
* Show the fullscreen search "home page" (from #1977) at /search
* Allow 'region=' parameter to be passed to /search
* Other minor fixes
