Bug 80719 – Allow WebFileChooser to return extra file info (like displayName) in addition to mere file paths

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Kinuko Yasuda]

Allow WebFileChooser to return extra file info (like displayName) in addition to mere file paths.

On some filesystems/platforms we want to use a separate display name from the base part of the given platform file path.

E.g. we may want to keep a snapshot file of the selected file in a temporary directory with a cryptic name while it's being processed, but want to use a different human-readable display name for the name that is exposed as File.name or as filename= field in the content disposition.

This is only for WebKit API changes-- the callsites and WebCore part also need to be changed.

Please wait for approval from [e-mail] before submitting because this patch contains changes to the Chromium public API.

is the idea that didChooseFile will be deprecated and removed?  assuming that is the
case, then you might just want to use the same name for the new method.  (although,
perhaps it should be "didChooseFiles" instead of "didChooseFile"!)

Thanks.  I added corresponding WebCore changes with some FIXME comments.  The change may feel a bit noisy as we need to keep the existing methods as well not to break other ports.

Either one of the method should be deprecated.  I think probably we should eventually just rewind what we're doing now... I added FIXME comment about that, renamed it to didChooseFile, and also added another comment that we should consider renaming it to "didChooseFiles".

Wrong indentation.

I recommend to add constructors to FileChooserFileInfo, and make FileChooserFileInfo immutable.

We can't do this.
It's possible that a form control state saved by a browser without this patch, and it is restored by a browser with this patch.

This is interpreted as ISO-8859-1, and U+00FF and U+00FE are valid characters.
I recommend to use U+FFFF.

String::fromUTF8("\xEF\xBF\xBF")

I'm sorry that U+FFFF is also a wrong choice because it is an invalid character according to the standard.  Some string conversion code might break this characters.
I recommend another control characters such as \1.

Thanks, character handling is difficult.  Updated.
