I'm hoping to pick your brains about version control - not in its
general use, but in how to organise projects. Let me try and explain...
I have a product which, like any other, get upgraded over time and new
releases (tags) are made. Some clients use the "standard" version,
but they'll almost certainly require customisation to a couple of
files. E.g. language terminology and a logo:
* Clients don't need to be foreign speaking to require changes to this
file, they may simply use different terminology for the same objects
in the system. This can be quite a large dictionary of changes, not
just half a dozen key words.
The problem I'm having is managing all these different variations in
Subversion (or any folder system for that matter). This problem
doesn't really disappear by moving the customised data to the database
as I'd just end up storing SQL files. I've effectively ended up with
a branch for each client, with their own trunk, and their own tags.
So much of each client version is common to the standard trunk and I
end up doing a lot of manual replication to ensure all the client
trunks are kept in sync with the "standard" trunk, and that all
clients have their own tags marked accordingly. E.g.
This can be further complicated when certain clients require even
heavier customisation. In these instances, the majority of the code
is shared with the standard project, but they may require some
database changes on key tables, and a few screen changes to
accommodate this. I've ended up adopting a version scheme which is
essentially records both the client version and the standard version
on which it is based, i.e:
And in Subversion:
This isn't really a big burden when I'm managing only a few clients
(although it does seem unnecessarily repetitive), but as this numbers
grow it becomes more a more unwieldy. I'm thinking there may be a
For example, by having one project for the whole of the standard code
base and versions, and a second project for managing the few files
that are likely to change between clients. E.g.
When making a release, I then merge the two together using a tool such
Does anyone manage a similar scenario? I'd be interested to know how
they do it, and where I can ease the maintenance burden.
