Feathercoin specific changes made to convert Bitcoin to FTC 0.9.6.*

https://github.com/FeatherCoin/Feathercoin/commit/bbfe772b5ce815bb429e74443b7b0f02cdda3354

bitcoin.cpp

bitcoin.cpp contains a number of Feathercoin settings.

Review, could be specified as an alternate file at build time?

 +/** Class encapsulating Feathercoin Core startup and shutdown.

Name change / new FTC file – for comment?

+/** Main Feathercoin application object */

Name change for comment?

+    QMessageBox::critical(0, "Runaway exception", BitcoinGUI::tr("A fatal error occurred. Feathercoin can no longer continue safely and will quit.") + QString("\n\n") + message);

Aren’t these all covered by displaying the translation text anyway? Review translations as Bitcoin -> Feathercoin message change. Does translatios stil fit or do they have to be bought in from Litecoin - how did Lizhi handle that?

 +  WId BitcoinApplication::getMainWinId() const
 +  {
 +      if (!window)
 +          return 0;
 +  
 +      return window->winId();
 +  }
 +  

+    SetupEnvironment();

Code added, interface change.

 +
 +    GUIUtil::SubstituteFonts();
 +

Change from default font handling

 +    QMessageBox::critical(0, QObject::tr("Feathercoin Core"),

Message box name change.

 -    ReadConfigFile(mapArgs, mapMultiArgs);
 +      try {
 +          ReadConfigFile(mapArgs, mapMultiArgs);
 +      } catch(std::exception &e) {
 +          QMessageBox::critical(0, QObject::tr("Feathercoin Core"),
 +                                QObject::tr("Error: Cannot parse configuration file: %1. Only use key=value syntax.").arg(e.what()));
 +          return false;
 +      }

Code replaced, scrypt interface.

 +        QMessageBox::critical(0, QObject::tr("Feathercoin Core"), QObject::tr("Error: Invalid combination of -regtest and -testnet."));

Name change to Feathercoin in

   +    // feathercoin: links repeatedly have their payment requests routed to this process:

Name change in a comment, review.

 -    // Install qDebug() message handler to route to debug.log
  #if QT_VERSION < 0x050000
 +      // Install qDebug() message handler to route to debug.log
 qInstallMsgHandler(DebugMessageHandler);
  #else
 +  #if defined(Q_OS_WIN)
 +      // Install global event filter for processing Windows session related Windows messages (WM_QUERYENDSESSION and WM_ENDSESSION)
 +      qApp->installNativeEventFilter(new WinShutdownMonitor());
 +  #endif
 +      // Install qDebug() message handler to route to debug.log

Debug interface change

 +  #if defined(Q_OS_WIN) && QT_VERSION >= 0x050000
 +          WinShutdownMonitor::registerShutdownBlockReason(QObject::tr("Feathercoin Core didn't yet exit safely..."), (HWND)app.getMainWinId());
 +  #endif

Scrypt interface bug fix close down windoze ?

[FAQ] What is SED?

sed is a stream editor. A stream editor is used to perform basic text transformations on an input stream (a file or input from a pipeline). While in some ways similar to an editor which permits scripted edits (such as ed), sed works by making only one pass over the input(s), and is consequently more efficient. But it is sed’s ability to filter text in a pipeline which particularly distinguishes it from other types of editors.

Tooltip interface change?

     // Set icon state: spinning if catching up, tick otherwise
 -    if(secs < 90*60 && count >= nTotalBlocks)
 +    if(secs < 90*60)

If conditions changed.

Feathercoin specific changes made to convert Bitcoin to FTC 0.9.6.*
