Feature proposal : package diff

[borisschapira]

It could be interesting, in order to optimize faster deployments, to be able to package a version with another package as parameter : the newly constructed version would only contains files which are different from the ones provided in this package.
We could reduce drastically the size of the update packages, mainly composed of little bugfixes or evolutions (but on the server-side, a full release would be created, copying the specified one and overwriting only what's need to be overwritten).

Yeah i totally agree with this idea.

But one big question are still open 👍

• How the packager system may generate the diff? Keep all previously generated package? Use an option to take an existing package and generate the diff with it? Use vcs system?...

• Packaging-side : take an existing package and generate the diff with it.
• Server-side : search for the release to copy and overwrite. If not found, extraction would be impossible.

Let's hope nobody will alter releases directly on the server, because he or she could jeopardize the future releases based on diff...
