versioning

I'm targetting IOS 4.3 and 5.0 with an app built against the 5.0 SDK and would like to add support for the Twitter functionality introduced in iOS5 only when the app runs on a iOS5 device. What is the recommended way to reliably test for the availability of these OS features at runtime without having your app crash? I know you do this using respondsToSelector in Objective-C but how is it done in C#? With recent MonoTouch versions you can use the following code: if (UIDevice.CurrentDevice.CheckSystemVersion (5, 0)) { window.RootViewController = navigation; } else { window.AddSubview (navigation

How can I edit an older revision's message to more correctly describe its changes? You cannot edit the commit message of an old revision without changing the revision id of the modified revision and all its descendants. Well... technically you can, if you try hard enough, but the technical term for the result is "corrupt repository". A repository in bzr is a replica of a distributed database of revisions, and if all replicas don't agree on the content of a revision, you have an integrity violation. Meaning, all bets are off, and the system will actively try to detect such situations and refuse

I have built an MSI that I would like to deploy, and update frequently. Unfortunately, when you install the MSI, and then try to install a newer version of the same MSI, it fails with a message like "Another version of this product is already installed. Installation of this version cannot continue..." appears. The MSI was built with a Visual Studio 2008 Setup Project. I have tried setting the "Remove Previous Versions" property to both true and false, in an effort to just make newer versions overwrite the older install, but nothing has worked. At a previous company I know I did not have this

I have a Jenkinsfile script that tests for the possibility to perform an SVN merge and then asks the user for the permission to commit the merge. I would like to know the username that answers the "input" step in order to write it into the commit message. Is this possibile? This is what hypothetically I would like to do: outcome = input message: 'Merge trunk into branch?', ok: 'Merge' echo "User that allowed merge: ${outcome.user}" The input step got an optional submitterParameter , which allows to specify the key of the returned Map that should contain the user who's submitting the input

Based on the answer here: Which, if any, recent Windows updates should I uninstall to revivify Silverlight or rectify other problems? , I uninstalled / reinstalled Silverlight and rebooted. Now, though, I get a compilation error, namely: "The imported project "C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v5.0\Microsoft.Silverlight.CSharp.targets" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk." It points to this line in a *.csproj file: <Import Project="$(MSBuildExtensionsPath32)\Microsoft\Silverlight\$(SilverlightVersion)\Microsoft
