How to share CCNET label across multiple projects and get incremented for each success build
There is already one post below where I have implemented this but it also increment for failure build also-
How to share CCNET label across multiple projects and get incremented for each build
Now here's how you can stop it to increment during failure builds-
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using Exortech.NetReflector;
using ThoughtWorks.CruiseControl.Core;
using ThoughtWorks.CruiseControl.Remote;
namespace ccnet.SharedLabeller.CruiseControl.plugin
{
[ReflectorType("sharedLabeller")]
public class SharedLabeller : ILabeller
{
///
/// The path where the file that holds the shared label should be located
///
/// none
[ReflectorProperty("sharedLabelFilePath", Required = true)]
public string SharedLabelFilePath { get; set; }
///
/// Any string to be put in front of all labels.
///
[ReflectorProperty("prefix", Required = false)]
public string Prefix { get; set; }
///
/// If true, the label will be incremented even if the build fails. Otherwise it will only be incremented if the build succeeds.
///
[ReflectorProperty("incrementOnFailure", Required = false)]
public bool IncrementOnFailure { get; set; }
///
/// Allows you to set the initial build number.
/// This will only be used when on the first build of a project, meaning that when you change this value,
/// you'll have to stop the CCNet service and delete the state file.
///
/// 0
[ReflectorProperty("initialBuildLabel", Required = false)]
public int InitialBuildLabel { get; set; }
public SharedLabeller()
{
IncrementOnFailure = false;
InitialBuildLabel = 0;
}
#region ILabeller Members
public string Generate(IIntegrationResult integrationResult)
{
if (ShouldIncrementLabel(integrationResult.LastIntegration))
{
return Prefix + IncrementLabel();
}
else
{
return integrationResult.LastIntegration.Label;
}
}
public void Run(IIntegrationResult integrationResult)
{
integrationResult.Label = Generate(integrationResult);
}
#endregion
private string IncrementLabel()
{
ThoughtWorks.CruiseControl.Core.Util.Log.Debug("About to read label file. Filename: {0}", SharedLabelFilePath);
using (FileStream fileStream = File.Open(this.SharedLabelFilePath,
FileMode.OpenOrCreate,
FileAccess.ReadWrite,
FileShare.None))
{
// read last build number from file
var bytes = new byte[fileStream.Length];
fileStream.Read(bytes, 0, bytes.Length);
string rawBuildNumber = Encoding.UTF8.GetString(bytes);
// parse last build number
int previousBuildNumber;
if (!int.TryParse(rawBuildNumber, out previousBuildNumber))
{
previousBuildNumber = InitialBuildLabel - 1;
}
int newBuildNumber = previousBuildNumber + 1;
// increment build number and write back to file
bytes = Encoding.UTF8.GetBytes(newBuildNumber.ToString());
fileStream.Seek(0, SeekOrigin.Begin);
fileStream.Write(bytes, 0, bytes.Length);
return newBuildNumber.ToString();
}
}
private bool ShouldIncrementLabel(IntegrationSummary integrationSummary)
{
return integrationSummary == null || integrationSummary.Status == IntegrationStatus.Success || IncrementOnFailure;
}
}
}
This is how you can implement in ccnet.config under project-
<sharedLabelFilePath>E:\Program Files\CruiseControl.NET\server\buildnumber.txtsharedLabelFilePath>
