[sca-assembly] [ISSUE 138] Assembly specification unclear on Contributionvs Deployment - when can errors in artifacts be reported? - UpdatedProposal 2

[Mike Edwards <mike_edwards@uk.ibm.com>]

Here is a proposal based on discussions
that have taken place on the email list and in prevoous TC calls:



Proposal:  

Add a new section to the spec after
line 3649 as follows:  

11.3. States of Artifacts in the Domain
 

Artifacts in the SCA domain are in one
of 3 states:  

1. Installed  
2. Deployed  
3. Running  

Installed artifacts are artifacts that
are part of a Contribution that is installed into the Domain.  
Installed artifacts are available for
use by other artifacts that are deployed, See "install Contribution"
 
and "remove Contribution"
to understand how artifacts are installed and uninstalled.  

Deployed artifacts are artifacts that
the SCA runtime is given to execute. Artifacts are deployed  
either through explicit deployment actions
or through deployment actions that act through  
<deployable/> elements present
in a sca-contribution.xml file within a Contribution. If an artifact is
deployed 
which has dependencies on other artifacts,
then those dependent artifacts are also deployed.  

When the SCA runtime has one or more
deployed artifacts, the runtime attempts to put those artifacts  
and any artifacts they depend on into
the Running state. This can fail due to errors in one or more of the artifacts
 
or the process can be delayed until
all dependencies are available.  

11.3.1  

Checking for errors in artifacts MAY
be done for artifacts when they are Installed (ie where the artifacts are
 
simply part of installed contributions]
[ASM120xx]  

Errors in artifacts SHOULD be detected
during the Deployment of the artifacts. [ASM120xx]


Errors in artifacts MUST be detected
no later than the process of putting the  
artifacts into the Running state, [ASM120xx]
