[wix-users] Switching Bundle Runtime during Update

Tue May 24 09:05:32 PDT 2016

I used the WixToolset implementation WixBA as my guide and other than implementing the InstallationViewModel and UpdateViewModel in a similar manner I did not need to do any additional downloads.  When the url is authored in the bundle using the Update/@Location I don't think I even had to add any call to SetUpdate as the code similar to that used by WixBA already handles all this behavior.  Once it detects a new version it sets UpdateState.Available, which the View uses to prompt the user.  If the user decides to do the update, then the UpdateCommand calls Engine.Plan with LaunchAction.UpdateReplace, which is what triggers Burn to manage starting the new bundle and terminating the current bundle, at least in my understanding.  (It may also be the case that in certain situations you may want to alter the url from that authored in the bundle Update/@Location, and then in that case when in DetectUpdateBegin you determine that a different url is needed, that is when I call SetUpdate to set a non-default url.  but that is a side issue that I would work on after the basic functionality of using the url authored I the bundle is working for you.)

I would add Engine.Log messages to each handler of concern and dump the EventArgs values into the log as you investigate the scenarios you are working with.

So within OnDetectComplete() in BaFunctions.dll I sucessfully download the update and then call the following.

m_pEngine->SetUpdate(NULL, updateExeFilePath.GetString(), size.QuadPart, BOOTSTRAPPER_UPDATE_HASH_TYPE_NONE, NULL, 0);

The updated executable does not get executed and the current active Bundle continues to install, why?

Thank you for the response.  Could you explain how you "inject a custom update on top of current WixStdBA"?

I've never done it from a BA function, as I've always injected my custom update handling on top of the current WixStdBA.

Since we do pass the engine to CreateBootstrapperBAFunction the BAF would have the engine pointer, however we don't have hooks for the OnDetectUpdate* events.  I'm guessing you could call it from OnDetectComplete.

How does this work within bafunctions.dll (hr = m_pEngine-->SetUpdate(...)?

At runtime the BA detects a new version is available and downloads, how is the Burn Engine informed of the new bundle?  So, now the value of WixBundleOriginalSource is obsolete and the new downloaded Bundle needs to be executed.

What is a "Bundle Runtime"? The Burn engine?

What is the proper procedure for switching the Bundle runtime after an update is detected and downloaded?
