Is there a way we could do this without using CF?

[Stephan Szabo]

We should be able to save them elsewhere rather than CF, will update.

WK1 and WK2 of Cocoa port shares saveRecentSearches.

Unfortunately, WK1 of Windows port is using CF.

You don't need "if (size)" because the following 'for' skips if size is zero.

According to the spec, you should include the size of the terminating null character.
You should use stringToNullTerminatedWChar.

You should use stringToNullTerminatedWChar.

WTF has makeUniqueArray which is using fastMalloc.

Why do you want to remove the comment? I think it should be preserved to explain WallTime::infinity.

I think in the Windows registry is a bad place to save recent searches.  It makes it hard to clear.  Shouldn't we just put it in a file on disk somewhere?

[Fujii Hironori]

I think WK1 and WK2 of WinCairo port should share the implementation of saveRecentSearches as well as Cocoa port does.

I wasn't entirely sure that sticking a file in the user's local application data would be better, but it seems like there's already data there for indexeddb and localstorage so that seems fine.

Should we do that as part of this, or make the new non-CF implementation and then update WK1 separately?

application data directory is much better for this sort of thing than the registry.  Implementations ought to be shared, and ideally wouldn't use CF.

Save search inputs to filesystem

Sorry about the long delay, had internal items then vacation.

Switching to using filesystem for the storage and replacing the SearchPopupMenuWin implementation as well.

Need to see if this is happy for win.

Do you need to include <WebCore/UserAgent.h> in this file?

Can `name` contain '/', '\', or '..'? How much is the maximum length? 
How do you think the idea using single SQLite database, for example 'search.db' instead of many files?

I think you shouldn't use 'WebCore::' in WebCore.

> Source/WebCore/platform/win/SearchPopupMenuWin.cpp:91
> +        auto nullTerminatedSearchItem = WTF::stringToNullTerminatedWChar(searchItems[i].string);

Remove 'WTF::' because there is using statement.

A version that saves to a sqlite db. I'd initially thought it might be overkill vs plain file, but it actually wasn't too bad.

This is almost platform independent. Remove 'Win'. It is OK for me to put this file in this platform/win/ dir until other ports reuse this.

Do you use <WebCore/FileSystem.h> in this file?

String ctor calls fastMalloc. Do not define String global variables.
Use WTF::ASCIILiteral instead.

Just updating for most of these, but a few comments.

Yes, I'm using pathByAppendingComponent and localUserSpecificStorageDirectory to generate the database file location.

Index is a reserved word in SQL, so we cannot name a column index (we could use "index" with the double quotes, but that becomes a bit of a mess). I'll change the name to position or something like that.

Since there's only a few specific statements, we can probably do without it as you mention. If this somehow ended up with a ton of statements it might be a problem, but that seems unlikely.

Sorry, looked back now and had misremembered that I moved the file location out to the DB cpp as well. Will kill that too.
