Re: RFC: File vitality

Looking at that forum thread, I have seen something similar, and it only affects the “Files-In-Use” dialog, NOT the actual file (that is not in use). The “affected” file never (in the instances I have seen, when I told Files-In-Use to ignore) was either a source of a conflict dialog nor a cause of actual reboot.

The only two types of support calls we received from this scenario are 1) from those that see Files-In-Use and freak out, calling support to ask why uninstall and/or upgrade should require a reboot when they had shut down the application already, and 2) from those that clicked Ignore and then called Support to log a bug because there was no reboot (since they expected one).

I was a long time ago surprised that the Vital setting wasn’t on by default. I would vote for on by default, and revert the default setting to off via candle command-line switch.

I would suggest this presumes that the person doing the install knows what they are doing! In a corporate environment that may be true and in that case you could build installs with vital off (having said that most of our installs are run silently so failing is a better option). I think the install failing is preferable to having a support call because one “vital” file is missing.

There is a recent PSDK.MSI thread where Simon Scott suspects a FilesInUse pattern bug:

 

http://groups.google.com/group/microsoft.public.platformsdk.msi/browse_thread/thread/17f76202ee2b2742/dc061211ad4db61a?lnk=raot

He thinks MSI is having a false positive on a locked file and that pressing ignore results in a successful instalation.  In this scenario, making all component files vital by default would actually result in a blocked installation.

 

It would be difficult to predict in advance of shipping a product which files might trip this possible bug so IMHO it might be best to leave vital not set and let the administrator roll the dice when choosing to hit ignore, retry or cancel.  If you don't, you'll be getting the support call anyways since the install rolled back.

occasions when making a file optional would be ok. I would guess that a
lot of installs (mine included) don't set this but that clicking
"ignore" would actually break the install.

I just posted a request for comments on my blog, to ask about a change
we're considering to simplify WiX authoring. You can see the post here:

http://www.joyofsetup.com/2008/05/03/rfc-vitality/

The short version is that we're considering marking all files with the
msidbFileAttributesVital bit set by default. That's a behavior change
and we wanted to get feedback before deciding either way. Please read
the whole post and let us know what you think, either via blog post
comments or mail on this list.
