Bug 125871 – Allow partial application of PlugInAutoStart tables based on timestamp

• Component: WebKit2
• Status: RESOLVED FIXED

[Ricky Mondello]

Allow clients of the PlugInAutoStart functionality to partially apply a table based on the timestamp of entries. More specifically, clients may find it useful to only apply policies created before a certain date to “roll back” changes to the table.

errrr-- "before time" in the function name, but let policies pass "after a certain time"?

> Source/WebKit2/UIProcess/API/C/WKContext.cpp:394

"Apply" seems like the wrong verb to use here. The method isn't taking the provided dictionary and amended the existing one with it, which is what I think of when I see "apply". Maybe something more along the lines of "SetPlugInAutoStartOrigins{BeforeTime,UsingTimeCutoff}"?

> Source/WebKit2/UIProcess/Plugins/PlugInAutoStartProvider.cpp:52
> +static double timeExpirationTimeWasGenerated(double expirationTime)

awkward naming. "originationTimeFromExpiration"?

> Source/WebKit2/UIProcess/Plugins/PlugInAutoStartProvider.cpp:121
> +void PlugInAutoStartProvider::setAutoStartOriginsTableWithItemsPassingTest(ImmutableDictionary const& table, std::function<bool(double timestamp)> predicate)

Wouldn't it be better for the predicate to be named properly, for readability in the code? Like "isExpirationTimeAcceptable"?
Also seems that proper style is "const ImmutableDictionary&".

Isn't it FilteringInEntriesAddedBeforeTime, or FilteringOutEntriesAddedAfterTime?

Yes. New bug/patch coming. Thank you for catching this.
