I'm not so sure. this is not related. the source code management right now mixes source code log of modification. EPICEA is about replacing the recovering crash kind of the tool (and more of course) but it is not about source. > > Thierry > -- > Thierry Goubier > CEA list > Laboratoire des Fondations des SystÃ¨mes Temps RÃ©el EmbarquÃ©s > 91191 Gif sur Yvette Cedex > France > Phone/Fax: +33 (0) 1 69 08 32 92 / 83 95 >

When I scan for method versions, I do, given a commitID, get the method + metadata. If the method path is dependent on which commitID I select, it becomes significantly more complex.

Why not just have a directory for the methods, and a single metadata file for categorising methods? We've talked on and off over the years about turning categories into tags (so a method could be in multiple categories), which this would allow. It would _also_ mean that recategorising a method wouldn't touch the file containing the method. frank > Thierry > -- > Thierry Goubier > CEA list > Laboratoire des Fondations des SystÃ¨mes Temps RÃ©el EmbarquÃ©s > 91191 Gif sur Yvette Cedex > France > Phone/Fax: +33 (0) 1 69 08 32 92 / 83 95 >
