Shared Label Plugin for CCNET
Recently, i have to develop plugin to share the build label across CCNET projects depending upon previously success or failure build. So, I came up with below solution in C#- using System; using System.Collections.Generic; using System.Linq; using System.Text; using ThoughtWorks.CruiseControl.Core; using ThoughtWorks.CruiseControl.Remote; using System.IO; using Exortech.NetReflector; namespace ThoughtWorks.CruiseControl.Core.labeller { // this is the labeller name that will be used in ccnet.config [ReflectorType("sharedLabeller")] public class SharedLabeller : ILabeller { [ReflectorProperty("sharedLabelFilePath", Required = true)] public string sharedLabelFilePath { get; set; } [ReflectorProperty("buildSuccessFile", Required = true)] public string buildSuccessFile { get; set; } [ReflectorProperty("alwaysincrement", Required = true)] public string alwaysincrement { get; set; } #region ILabeller Members public string Generate(IIntegrationResult previousResult) { if (ShouldIncrementLabel(previousResult)) return IncrementLabel(); if (previousResult.Status == IntegrationStatus.Unknown) return "0"; return previousResult.Label; } public void Run(IIntegrationResult result) { result.Label = Generate(result); } #endregion private string IncrementLabel() { if (!File.Exists(sharedLabelFilePath)) return "0"; using (FileStream fileStream = File.Open(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.ASCII.GetString(bytes); // parse last build number int previousBuildNumber = int.Parse(rawBuildNumber); int newBuildNumber=0; if (File.Exists(buildSuccessFile) && alwaysincrement=="yes") newBuildNumber = previousBuildNumber + 1; else newBuildNumber=previousBuildNumber; // increment build number and write back to file bytes = Encoding.ASCII.GetBytes(newBuildNumber.ToString()); fileStream.Seek(0, SeekOrigin.Begin); fileStream.Write(bytes, 0, bytes.Length); return newBuildNumber.ToString(); } } private static bool ShouldIncrementLabel(IIntegrationResult previousResult) { return (previousResult.Status == IntegrationStatus.Success || previousResult.Status == IntegrationStatus.Unknown); } } }
