The webgpu.h version that Dawn implements.WebGPU C/C++ headers that applications and other building blocks use.Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.ĭawn provides several WebGPU building blocks: More precisely it implements webgpu.h that is a one-to-one mapping with the WebGPU IDL. Edge also plans to change its default behaviors.Dawn is an open-source and cross-platform implementation of the work-in-progress WebGPU standard. To test these behaviors in Firefox, open about:config and set. Firefox has them available to test as of Firefox 69 and will make them default behaviors in the future. Cookies with SameSite=None must also specify Secure, meaning they require a secure context.Ĭhrome implements this default behavior as of version 84.Cookies without a SameSite attribute will be treated as SameSite=Lax.To encourage developers to state their intent and provide users with a safer experience, the IETF proposal, Incrementally Better Cookies lays out two key changes: The open default of sending cookies everywhere means all use cases work but leaves the user vulnerable to CSRF and unintentional information leakage. While the SameSite attribute is widely supported, it has unfortunately not been widely adopted by developers. Changes to the default behavior without SameSite # If you provide a service that other sites consume such as widgets, embedded content, affiliate programs, advertising, or sign-in across multiple sites then you should use None to ensure your intent is clear. This makes Lax a good choice for cookies affecting the display of the site with Strict being useful for cookies related to actions your user is taking. However when the reader follows the link through to cat.html on your blog, that request will include the cookie. When the reader is on the other person's blog the cookie will not be sent when the browser requests amazing-cat.png. Look at this amazing cat! Īnd the cookie has been set as so: Set-Cookie: promo_shown=1 SameSite=Lax They make use of your photo of the cat directly and provide a link through to your original article. Let's revisit the cat article example from above where another site is referencing your content. That's where SameSite=Lax comes in by allowing the cookie to be sent with these top-level navigations. If your reader follows the link into the site, they want the cookie sent so their preference can be applied. This is good when you have cookies relating to functionality that will always be behind an initial navigation, such as changing a password or making a purchase, but is too restrictive for promo_shown. However when following a link into your site, say from another site or via an email from a friend, on that initial request the cookie will not be sent. When the user is on your site, then the cookie will be sent with the request as expected. So, if the promo_shown cookie is set as follows: Set-Cookie: promo_shown=1 SameSite=Strict In user terms, the cookie will only be sent if the site for the cookie matches the site currently shown in the browser's URL bar. If you set SameSite to Strict, your cookie will only be sent in a first-party context. You can choose to not specify the attribute, or you can use Strict or Lax to limit the cookie to same-site requests. Introducing the SameSite attribute on a cookie provides three different ways to control this behaviour. Explicitly state cookie usage with the SameSite attribute # If the user is on and requests an image from that's a cross-site request.
