Replace Text in Streams

Today, I thought about replacing text in streams. I noticed that .NET 4 provides methods for type

String

to replace some text, but no methods for type

Stream

I found a way by converting the stream to a string in a first step and by replacing text in a second step.

new StreamReader(i).ReadToEnd().Replace("old text", "new text")

For a lot of cases this is alright and there is nothing to worry about. But if the source is a huge amount of data and I do not want to hold it in memory all the time, things get tricky. For these cases I wrote a simple method called

ReplaceTextInStream

The method gets four arguments: an input stream, an output stream, a string with a pattern to search for and a string with the replacement value. If one argument is null, a ArgumentNullException is thrown. Here is the code: Enjoy!

public static void ReplaceTextInStream(Stream input, Stream output, string pattern, string replacement) 
{
    if (input == null)
    {
        throw new ArgumentNullException("input");
    }
    if (output == null)
    {
        throw new ArgumentNullException("output");
    }
    if (pattern == null)
    {
        throw new ArgumentNullException("pattern");
    }
    if (replacement == null)
    {
        throw new ArgumentNullException("replacement");
    }
    StreamReader r = new StreamReader(input);
    StreamWriter w = new StreamWriter(output);
    // Input and Pattern are empty => Output = Replacement
    if(input.Length == 0 && pattern.Length == 0) 
    {
        w.Write(replacement);
    }
    // Pattern is empty => Output = Input
    if (input.Length != 0 && pattern.Length == 0)
    {
        while (!r.EndOfStream)
        {
            w.Write((char)r.Read());
        }
    }
    // Init empty Stack
    List<char> stack = new List<char>();
    // Loop over input characters
    while (!r.EndOfStream)
    {
        // Read next input character
        char c = (char)r.Read();
        // Compare characters
        if (pattern[stack.Count] == c)
        {
            // Match => Put it on Stack
            stack.Add(c);
            // Match complete?
            if (stack.Count == pattern.Length)
            {
                // Write Replacement and clear Stack
                w.Write(replacement);
                stack.Clear();
            }
        }
        else
        {
            // No Macth => Stack filled?
            if (stack.Count != 0)
            {
                // Write and Clear Stack
                foreach (var tc in stack)
                {
                    w.Write(tc);
                }
                stack.Clear();
            }
            // Copy current character
            w.Write(c);
        }
    }
    // After Loop: Stack filled?
    if (stack.Count != 0)
    {
        // Write and Clear Stack
        foreach (var tc in stack)
        {
            w.Write(tc);
        }
        stack.Clear();
    }
    w.Flush();
}

Resumed Orchestration Instances are not processed

Today, in BizTalk 2009 I runned into the following problem: I resumed orchestration instances. They get a processing server, but they are not processed. The orchestration debugger showed, that nothing has happened. Restarting host instance does not change anyhting. Running the MsgBoxViewer showed a MsgBox database integrity problem. The text said

Missing Restart Msg in Spool table (can prevent some svc instances to be resumed, terminated or suspended) !!

Missing Suspend Msg in Spool table (can prevent some svc instances to be resumed, terminated or suspended) !!

Missing Terminate Msg in Spool table (can prevent some svc instances to be resumed, terminated or suspended) !!

Missing ResumeInDebugMode Msg in Spool table (can prevent some svc instances to be resumed, terminated or suspended) !!

Following the hint to run the Terminator tool is not necessary. Just do THIS. Afterwards, restart the host instances. All running, but not processed orchestration instances are processed.
