Ahh, so you are doing your own downloading of the atom feed. In 3.9, the
engine will download the feed automatically if IDOK is returned from
OnDetectUpdateBegin and there is an <Update /> element in the BA's manifest.
It is possible that the changes I made to the engine are triggering an
unintended side effect, but I can't see a clear path for how it could happen.
In DetectUpdateBegin, are you doing anything to the result? IE, are you
modifying e.Result? It should default to IDNOACTION, but if you returned IDOK
then the engine would attempt to download and parse your Atom feed for you, and
notify your BA of what it finds for updates via a series of callbacks to
OnDetectUpdate. If you aren't modifying e.Result, then the changes I
implemented in the engine should not impact you.
A snip from the WixBA:
SyndicationFeed feed;
using (XmlReader reader =
XmlReader.Create(response.GetResponseStream()))
{
feed = SyndicationFeed.Load(reader);
}
var updates = from entry in feed.Items
from link in entry.Links
from extension in entry.ElementExtensions
where String.Equals(link.RelationshipType,
"enclosure", StringComparison.Ordinal) &&
String.Equals(extension.OuterNamespace,
this.AppSyndicationNamespace, StringComparison.Ordinal) &&
String.Equals(extension.OuterName,
"version", StringComparison.Ordinal)
select new Update()
{
Url = link.Uri.AbsoluteUri,
Size = link.Length,
Version = new
Version(extension.GetObject<string>())
};
Update update = updates.Where(u => u.Version >
WixBA.Model.Version).OrderByDescending(u => u.Version).FirstOrDefault();
if (update == null)
{
WixBA.Model.Engine.SetUpdate(null, null, 0,
UpdateHashType.None, null);
this.State = UpdateState.Current;
}
else
{
WixBA.Model.Engine.SetUpdate(null, update.Url,
update.Size, UpdateHashType.None, null);
this.State = UpdateState.Available;
}
Is it getting the right update from " Update update = updates.Where(u =>
u.Version > WixBA.Model.Version).OrderByDescending(u =>
u.Version).FirstOrDefault(); " ?
What values are you passing to SetUpdate? IE, are you passing the incremental
update, or the largest update?

Subject: Re: [WiX-users] 3.9.702 Bundle update behavior
My mba which has been working in this regard for about a year, is based on the
Wix toolset Setup\WixBA\UpdateViewModel code which implements DetectUpdateBegin
and DetectComplete. Some time ago I added some customization to these handlers
to allow our build process to place builds into a dev, test, and live area, and
allow the mba to detect whether the setup is running on a marked dev or test
system and get builds from those staging areas. But those changes have also
been working prior to seeing this new behavior.
DetectUpdateBegin spawns worker_DoWork which calls Engine.SetUpdate and return
codes. This code is the same as in the wix toolset source.
My atom feed document is generated at build time and I only include information
for the one build that I intend to post to the web site, so it surprised me
that the other intermediate bundles (other than the one the user launched) were
still around on the local system to be reused.
