Drafting the patches to HTML

[jakearchibald]

Given the recent confusion on navigation, now sounds like the right time to draft up a table, or patches for fetches.

Happy to do the work here, but @wanderview, you said you had a list of things that fetch to use as a starting point?

[jakearchibald]

Notes:

• I'm mapping "synchronous" to the blocking flag in the current html fetch algorithm, which may not be correct

<a ping>

• Current 'fetch' point: https://html.spec.whatwg.org/#hyperlink-auditing:ping
• client: window containing the hyperlink
• synchronous flag: unclear, but I'd guess unset
• skip-service-worker flag: unset
• mode: no-cors
• credentials mode: include
• cache mode: no-store (unsure)
• redirect mode: follow

Appacache Manifest check

• Current 'fetch' point: https://html.spec.whatwg.org/#downloading-or-updating-an-application-cache step 4
• client: the window that triggered the update
• synchronous flag: set
• skip-service-worker flag: set, I guess, but SW disables appcache
• mode: same-origin
• credentials mode: include
• cache mode: default
• redirect mode: error

Appcache resource fetch

• Current 'fetch' point: https://html.spec.whatwg.org/#downloading-or-updating-an-application-cache step 17.3
• client: the window that triggered the update
• synchronous flag: set
• skip-service-worker flag: set, I guess, but SW disables appcache
• mode: no-cors
• credentials mode: include
• cache mode: default
• redirect mode: error

CSP violation report

• Current 'fetch' point: https://w3c.github.io/webappsec/specs/CSP2/#send-violation-reports 3.2
• client: the client the report was generated against
• synchronous flag: unset
• skip-service-worker flag: unset
• mode: no-cors
• credentials mode: same-origin
• cache mode: no-store (unsure)
• redirect mode: error

Navigation

Also applies to downloading, view-source.

• Current 'fetch' point: https://html.spec.whatwg.org/#navigating-across-documents 15
• client: null
• synchronous flag: set
• skip-service-worker flag: unset
• mode: same-origin
• credentials mode: include
• cache mode: default
• redirect mode: manual

EventSource

• Current 'fetch' point: https://html.spec.whatwg.org/#eventsourceinit 7
• client: from current environment settings object
• synchronous flag: set (although not specified)
• skip-service-worker flag: unset
• mode: cors
• credentials mode: same-origin, or include if withCredentials used in constructor
• cache mode: no-store (not sure)
• redirect mode: follow

<audio> and <video>

• Current 'fetch' point: https://html.spec.whatwg.org/#concept-media-load-resource 4.remote.2
• client: from current environment settings object
• synchronous flag: set
• skip-service-worker flag: unset
• mode: no-cors, unless element has crossorigin attr, in which case cors
• credentials mode: same-origin, unless crossorigin=use-credentials, in which case include
• cache mode: default
• redirect mode: follow

This request fails on "error code" responses.

<script>

• Current 'fetch' point: https://html.spec.whatwg.org/#prepare-a-script 14.5
• client: from current environment settings object
• synchronous flag: set
• skip-service-worker flag: unset
• mode: no-cors, unless element has crossorigin attr, in which case cors
• credentials mode: same-origin, unless crossorigin=use-credentials, in which case include
• cache mode: default
• redirect mode: follow

This request fails 404 and probably other error-code responses (although only 404 is specified).

<track>

• Current 'fetch' point: https://html.spec.whatwg.org/#start-the-track-processing-model 10
• client: from current environment settings object
• synchronous flag: set
• skip-service-worker flag: unset
• mode: no-cors, unless parent media element has crossorigin attr, in which case cors
• credentials mode: same-origin, unless parent media element has crossorigin=use-credentials, in which case include
• cache mode: default
• redirect mode: follow

This request fails on "error code" responses.

More to come…

How about Worker and SharedWorker?
https://html.spec.whatwg.org/#run-a-worker

[annevk]

I filed whatwg/html#95 on HTML. I hope to work on this soonish, but it seems some more groundwork in Fetch is required first.

[annevk]

whatwg/html#144 is a rewrite of the text in the HTML Standard. It also addresses workers. Review would be appreciated.

[annevk]

Note that #126 will change what we do for navigation requests @dstockwell.

I think this should be closed since it's no longer relevant. @jakearchibald?

[dstoc]

It's amusing that github wants to give me credit for all blink commits, but that was actually @horo-t

[annevk]

Ah, @horo-t should probably add "horo@chromium.org" to his GitHub email addresses to rectify that.

Happy to close this
