Hello all,
Platform and Client team of XWiki SAS find interesting the idea of having
XWiki version written as comment in the top of xwiki.cfg (no need for
particular location though).
When an upgrade is performed, it would permit to know if this configuration
file has been merged (new xwiki version) or directly moved (first/previous
xwiki version) from the old webapp.
Do you think it would be feasible?
Thank you in advance.

Yes, it's quite easy to do. This file is already being generated by
Maven during the build.

How do you think it would work?
* Imagine you have version N installed.
* Now you've upgraded your WAR to version N+1
* You merge the xwiki configuration files
. If you don't edit their versions you still have version N mentioned and it's
even worse than before because the next person that comes will see and *trust* that
you're at version N when you're actually at version N+1.
I don't see how having a comment with the current version will help… I fear it might
do the opposite...
Actually the config file is supposed to stay stable as you're supposed to use the same
config version across xwiki versions. In the future it'll need to be in the data dir
(except for the location of the data dir which should be something defined in the startup
script as it is now btw ;)).
OTOH we could offer first some tools to upgrade the configuration files. We use sdiff for
example to upgrade myxwiki.org:
sudo mv xwiki.new/WEB-INF/web.xml xwiki.new/WEB-INF/web.xml.ori; sudo sdiff
xwiki/WEB-INF/web.xml xwiki.new/WEB-INF/web.xml.ori -B -W -E -o xwiki.new/WEB-INF/web.xml
sudo mv xwiki.new/WEB-INF/xwiki.cfg xwiki.new/WEB-INF/xwiki.cfg.ori; sudo sdiff
xwiki/WEB-INF/xwiki.cfg xwiki.new/WEB-INF/xwiki.cfg.ori -B -W -E -o
xwiki.new/WEB-INF/xwiki.cfg
sudo mv xwiki.new/WEB-INF/xwiki.properties xwiki.new/WEB-INF/xwiki.properties.ori; sudo
sdiff xwiki/WEB-INF/xwiki.properties xwiki.new/WEB-INF/xwiki.properties.ori -B -W -E -o
xwiki.new/WEB-INF/xwiki.properties
sudo mv xwiki.new/WEB-INF/struts-config.xml xwiki.new/WEB-INF/struts-config.xml.ori; sudo
sdiff xwiki/WEB-INF/struts-config.xml xwiki.new/WEB-INF/struts-config.xml.ori -B -W -E -o
xwiki.new/WEB-INF/struts-config.xml
sudo mv xwiki.new/templates/admin.vm xwiki.new/templates/admin.vm.ori; sudo sdiff
xwiki/templates/admin.vm xwiki.new/templates/admin.vm.ori -B -W -E -o
xwiki.new/templates/admin.vm
sudo mv xwiki.new/WEB-INF/classes/logback.xml xwiki.new/WEB-INF/classes/logback.xml.ori;
sudo sdiff xwiki/WEB-INF/classes/logback.xml xwiki.new/WEB-INF/classes/logback.xml.ori -B
-W -E -o xwiki.new/WEB-INF/classes/logback.xml
That makes it quite easy to upgrade.
For a further future, we could imagine offering a UI in an upgrade wizard (just before the
distribution wizard runs) to let the user discover new configuration options, deprecated
ones and removed ones. We would just need to add some metadata somewhere in XWiki to
indicate that.

Thank you in advance.

The first idea was to merge old configuration lines to the new xwiki.cfg,
which means the version is correct when files are correctly merged. The
issue is also that some lines need to be remove from xwiki.cfg (like
workdir, which is useless in 5.x for example).
Being able to follow the version number could be useful in this case.
Upgrade wizard sounds nice BTW :)

It is not wrong doc for our distributed configuration files. So nothing to
fear, this why I do not understand why you seems to be against that
comment. What will be done with it later is up to the user, and you cannot
prevent him to do stupid things.

I don't see how having a comment with the current version will help… I
fear it might do the opposite...
I do not understand what you fear, a comment saying "Configuration file
distributed with XWiki version x.y.z" could not really cause an issue to
the merge process, and could help the way Guillaume said without causing
any misinformation from our side anyway.
Administrators could do tons of stupid things while merging, it does not

And to reiterate on what I mentioned in my first reply, a much better

But I fail to see how adding the version would help for this, except if the user updates
the version comment himself after he merges with the new version. But he can do already by
adding a comment…

I do not understand what you fear, a comment saying "Configuration file
distributed with XWiki version x.y.z" could not really cause an issue to
the merge process, and could help the way Guillaume said without causing
any misinformation from our side anyway.
Administrators could do tons of stupid things while merging, it does not
matter.
I explained the risk in my mail but I was probably not clear.
Summary:
Having wrong doc is worse than having no doc. Details:
Having a "Configuration file distributed with XWiki version x.y.z"
information is pretty much useless since this file is **mean*t* to be
modified so the information is only valid if you **don't** modify the file.
As soon as you make one modification it's no longer valid and
wrong/misleading for anyone who comes after and read it.
And to reiterate on what I mentioned in my first reply, a much better
solution IMO is:
* Look for xwiki configuration files first in the permanent dir
* If not found there, use the default config files provided with the WAR

In production, since currently configuration files are in the war and
should be customized, we need to unzip the war, and therefore the
configuration file does not have anymore a version the way you seems to
expect.
I still do not understand why you fear that much to state in a file what is
it really.

Summary:
Having wrong doc is worse than having no doc.
fear, this why I do not understand why you seems
to be against that
comment. What will be done with it later is up to the user, and you
cannot
prevent him to do stupid things.
This file is not distributed separately. We always distribute it with our
WAR and thus it already has a version: the one of the WAR. I don't see what
would be provided more by adding a version info in it. However I can easily
see what can go wrong by doing that.
Guillaume said:
"When an upgrade is performed, it would permit to know if this
configuration
file has been merged (new xwiki version) or directly moved (first/previous
xwiki version) from the old webapp."
But I fail to see how adding the version would help for this, except if
the user updates the version comment himself after he merges with the new
version. But he can do already by adding a comment…
If you proceed to an automated tree-way merge, based on, let say:
"Configuration file distributed with XWiki version a.b.c" in the original
war for version n-1
"Customized configuration file for XWiki version a.b.c" in your old webapp
"Configuration file distributed with XWiki version x.y.z" in the new war
for version n
You will surely god what Guillaume expects, which would be "Customized
configuration file for XWiki version x.y.z", and will allow
to differentiate this file from the simple copy of the file from the old
webapp. So, the point of Guillaume is not that bad when used properly.

As soon

For sure, this is what we want. And the default file could keep a comment
like the one I suggested, this is just the next step.
