Subject [jira] Commented: (GERONIMO-4130) Unable to preserve comments from plan.xml into config.xml
Date Thu, 20 May 2010 21:09:18 GMT


Jay D. McHugh commented on GERONIMO-4130:

This ticket has two parts.  The original issue was enabling and disabling services.  The issue
of comments came up because that used to be the way to accomplish enabling and disabling services.

I think that the issue of enabling and disabling services is already handled by the 'load'
attribute of the 'module' entities.  If I am mistaken about using the load attribute to control
whether a particular module starts or not then this ticket is valid.  And we need to make
sure that there is a simple and straight forward way to determine which modules are started
(we also need to make sure that the title of this ticket is changed to reflect the actual

If the load attribute does control which modules actually start, then the use of comments
in the config.xml file is a completely separate issue.  And, it should get it's own (new)

Here is a discussion of how comments are being handled in the config.xml and why.  If anyone
thinks that it would be worthwhile to handle 'true XML comments' then we should open a new
ticket to track that.

There is a problem with using 'real' comments.  And that problem is that the tools that are
being used to parse the XML files completely ignore them.

So, whenever one of these files are parsed and then recreated - the comment would be lost.
 That is why the <comment> tag was used in the first place.  Comments are normally 'for
human consumption' only.  We needed to put them into the actual XML data in order to tell
the parser that they really are a part of the data and not just fluff for people to read.

The config.xml file is read in during server start up and recreated from scratch during shutdown.
 Real XML style comments (and their location within the file) do not appear to be maintained
by the parser/builder.  We would need to make our own XML parser that internally converted
the comments into XML data and a new XML builder that would re-convert that special comment
data back into actual comments.

Sorry that it took so long for me to realize that I was answering a different problem than
the real issue.  


Have I finally seen the problem that you were trying to bring up (modifying which services

Do you still think that there is a problem with how comments are being handled?

> It was easy in previous releases, as we could provide comment in config.xml and tell
the users to "To disable accesslogging uncomment the following section...".   However, with
our new config.xml, we don't preserve any comments, which makes hard for users to config things.
