[WebKit] WebDatabase openDatabase()

This is a simple memo for myself about web sql databse function flow.

Java script code

  var db = openDatabase("Todo", "1.0", "Todo manager", 1024*1024);

WebKit code

// call window.openDatabase

PassRefPtr<Database> DOMWindowSQLDatabase::openDatabase(DOMWindow* window, const String& name, const String& version, const String& displayName, unsigned long estimatedSize, PassRefPtr<DatabaseCallback> creationCallback, ExceptionCode& ec)

// Database::openDatabase
PassRefPtr<Database> Database::openDatabase(ScriptExecutionContext* context, const String& name, const String& expectedVersion, const String& displayName, unsigned long estimatedSize, PassRefPtr<DatabaseCallback> creationCallback, ExceptionCode& e)

// call Database & AbstractDatabase constructor

Database::Database(ScriptExecutionContext* context, const String& name, const String& expectedVersion, const String& displayName, unsigned long estimatedSize) : AbstractDatabase(context, name, expectedVersion, displayName, estimatedSize, AsyncDatabase) , m_transactionInProgress(false) , m_isTransactionQueueEnabled(true) , m_deleted(false)

// Insert database into tracker (called in constructor of AbstractDatabase)

String DatabaseTracker::fullPathForDatabase(SecurityOrigin* origin, const String& name, bool createIfNotExists)

String DatabaseTracker::fullPathForDatabaseNoLock(SecurityOrigin* origin, const String& name, bool createIfNotExists)

bool DatabaseTracker::addDatabase(SecurityOrigin* origin, const String& name, const String& path)

// open database

bool Database::openAndVerifyVersion(bool setVersionInNewDatabase, ExceptionCode& e, String& errorMessage)

bool Database::performOpenAndVerify(bool setVersionInNewDatabase, ExceptionCode& e, String& errorMessage)

void DatabaseThread::recordDatabaseOpen(Database* database)

// set database detail infomation

void DatabaseTracker::setDatabaseDetails(SecurityOrigin* origin, const String& name, const String& displayName, unsigned long estimatedSize)

>> return RefPtr<Database>
