[Pkg-bitcoin-devel] Bug#696715: bitcoin-qt: Should not exit when disk space is low

[Petter Reinholdtsen]

Package: bitcoind
Version: 0.7.2-1

The bitcoin client exits when the disk space is running low while
downloading blocks.  This is not the most elegant way to handle it, as
the daemon from a user perspective just disappers without a trace.  A
better way would be to pause the block downloading until the disk space
situation improves.  The CheckDiskSpace() function in src/main.cpp is
the one triggering this behaviour.  It contain this code:

    // Check for nMinDiskSpace bytes (currently 50MB)
    if (nFreeBytesAvailable < nMinDiskSpace + nAdditionalBytes)
    {
        fShutdown = true;
        string strMessage = _("Warning: Disk space is low!");
        strMiscWarning = strMessage;
        printf("*** %s\n", strMessage.c_str());
        uiInterface.ThreadSafeMessageBox(strMessage, "Bitcoin", CClientUIInterface::OK | CClientUIInterface::ICON_EXCLAMATION | CClientUIInterface::MODAL);
        StartShutdown();
        return false;
    }

I noticed the problem with bitcoin-qt, where a dialog about "disk full"
is shown and when I click 'OK' the program just disappears.  The code
seem to affect bitcoind too.
