Add Blackfire.io to the whitelist of oembed providers

[romainneutron]

Hello,

this patch adds Blackfire.io as oEmbed provider to ease Blackfire graphs integration. For example

​https://blackfire.io/oembed?url=https%3A//blackfire.io/profiles/ffcffdc1-50db-42bc-bcbb-dcfe86758e26/graph&format=json

Blackfire.io is a young startup that provide very easy-to-use tools for profiling PHP apps. For example, here's the result we propose for a Symfony demo app : ​https://blackfire.io/profiles/ffcffdc1-50db-42bc-bcbb-dcfe86758e26/graph

We love wordpress and already talked about it: ​http://blog.blackfire.io/improving-wordpress.html

Regards,

Romain

Thanks for the patch, romainneutron!

As part of our process for whitelisting new oEmbed providers we assess the provider based on a set of standards. Can you ​take a look at our Whitelisting oEmbed Providers page in the handbook at provide us with answers to the questions please?

Thanks in advance.

Since #32522 just landed, oEmbed providers which provide oEmbed discovery links in their header are now supported by default, and embedding is allowed via a strictly sanitized iframe.

Since this covers Blackfire.io (it includes both application/json+oembed and application/xml+oembed links in its header, thus allowing oEmbed discovery), I'm going to close this as wontfix, particularly because Blackfire.io is a relatively new service and would likely not have been whitelisted at this point anyway.

Yay for oEmbed discovery!
