Bug 69598 – Pass Parsed Accept Attribute MIME Types to WebKit Clients

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Joseph Pecoraro]

Rather then have each of the WebKit clients parse the MIME types from the
accept attribute string via FileChooser, WebCore should parse the string
and pass a list. WebCore already has the HTML5 compatible parser logic.

NOTE: Chromium is the only client that uses the "acceptType" attribute of
FileChooser right now. They pass it along as a string and parse it later
in chromium code.

[PATCH] Proposed Fix

I think this is the preferable approach. Rather then passing the "accept" attribute string
to WebKit clients, we instead pass the parsed list of trimmed MIME types. This way
ports don't have to write their own, possibly differing parsing implementations and
we can make use of the HTML5 parsers already in WebCore.

I'm not very familiar with WK2, but this looks like it would affect the WebKit2 API.
Does that require any special considerations?

Clearing flags. Based on some feedback I'm going to do some extra clean-up and break this up into parts.

[PATCH] Part 1 - Deprecate String version of acceptTypes

Chromium folks, check out Part 3 when it is up. Instead of parsing the mime types
in chromium WebKit ports should share the implementation in WebCore.

Looks like the EFL port also used this and exposed it to their api as a char*:

    Eina_Bool (*run_open_panel)(Ewk_View_Smart_Data *sd, Evas_Object *frame, Eina_Bool allows_multiple_files, const char *accept_types, Eina_List **selected_filenames);

If they want to move away from the deprecated type It looks like they could upgrade
their API to use an Eina_List* for the MIME types list. I'll update Part 1.

Part 1 and Part3 look reasonable.  Please fix build failures of GTK and Windows.

I forgot to change the WebKit2 one that gets removed in the next patch. I retroactively
created the patches. Lets give this one a shot on the bots, while my system is having
a little bit of trouble building in general.

Landed the 3 Parts in:
http://trac.webkit.org/changeset/97336
http://trac.webkit.org/changeset/97337
http://trac.webkit.org/changeset/97338

[Joseph Pecoraro]

The bots look good.

I think this is the first time I had 3 patches reviewed by 3 different people. Thanks for coming together!

To remove the deprecated string I filed bugs on EFL and Chromium:
<http://webkit.org/b/70002> [EFL]: Move from FileChooserSettings deprecatedAcceptType to acceptMIMETypes
<http://webkit.org/b/70003> [Chromium]: Move from FileChooserSettings deprecatedAcceptType to acceptMIMETypes
