           Summary: WebChromeClient.cpp is buggy on Windows
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: New Bugs
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: dumi at chromium.org

1. Delete all Safari HTML5 databases.
2. WebKitTools/Scripts/build-webkit --debug (not sure if the --debug flag
changes anything, but i haven't tried this in release mode)
3. WebKitTools/Scripts/run-safari --debug
4. Run any code that tries to open a database.

RESULTS: openDatabase() fails (returns NULL)

EXPECTED: openDatabase() succeeds.

PROBLEM: When we try to open a database in a new origin (that is not in the
tracker database Databases.db), DatabaseTracker::canEstablishDatabase() makes a
call to ScriptExecutionContext::databaseExceededQuota(), which eventually calls
WebChromeClient::exceededDatabaseQuota(), which is supposed to give this new
origin 5MB of space. That does not happen:
WebChromeClient::exceededDatabaseQuota() calls some private delegate, which
does not change anything, as far as the database code is concerned.

This problem does not exist in Safari. It only shows up when running Safari
using the WebKit library built from the open source tree.
