[Geoserver-devel] Revamping GSIP-45

GeoServer GeoServer Developer
1

Hi all,

We'd like to revamp the GSIP-45
http://geoserver.org/display/GEOS/GSIP+45+-+Moving+GeoServer+model+in+a+standalone+module
Here's the related R'n'D page:
http://geoserver.org/display/GEOS/Resource+*Info+beans+refactoring

There have already been some discussion about it, and the proposed
implementation changed after some ideas from Justin:
http://www.mail-archive.com/geoserver-devel@lists.sourceforge.net/msg09231.html

This refactoring is quite important for better supporting integration with
external application. Please note that also the rest-client community module
had to reimplement its own model, mirroring the existing one.

   Ciao,
   Emanuele

How does it relate to GSIP-52? http://geoserver.org/display/GEOS/GSIP+52±+Refactor+out+DAO+for+Catalog+and+Configuration

It might be easier to just make a new GSIP, that refers to 52, and proposes with regards to that, and addresses everything brought up in the gsip 45 email thread.

And what’s the timeframe you would do the work in? I was hoping we’d be moving to RC1 the first week of January, and this sounds like a potential major change that would push that back? Or did you want to target 2.2.x?

Justin’s on vacation, but I think it’s pretty important that he sound in. Hopefully he has some time to respond.

I can’t quite remember where the idea left off but I remember coming to a good consensus. The highlights of which from memory are:

  • a pure refactoring with zero behavior changes
  • the new model model interfaces maintain and identical structure to the current ones except they are 1) prefixed with “I” and 2) all dependencies for “resource loading” are removed
  • the impl classes are factored out along with the interfaces
  • the existing interfaces implement the new ones and there should be any client code changes

Anything I am missing? With that the impact in terms of code base should be minimal. A new module called “api” (or something) and changes to the core config and catalog to implement the new interfaces and extend the new implementation classes.

Ciao Chris,

as Justin has already pointed out, this will be a pure refactoring with zero
behavior changes, so I guess the description in the existing R'n'D and GSIP
pages should be enough.

We are planning to release these changes in 2.2.x , so the RC1 will not be
affected.

   Ciao,
   Emanuele

Ciao Justin,

the planned changes are exactly the ones you cited.

Dear All,
just to clarify a little bit.
In principle the changes should be minimal as pointed out by justin, although I don’t think we will have enough time to do this within the timeframe of the 2.1, therefore I wold emanuele to shoot for the 2.2 and coordinate with justin on the db work.

Simone.
