Subject RES: Libraries and projects into SVN
Date Tue, 14 Aug 2012 14:05:30 GMT

The system here is a bit complex and I will try to explain it.

We have two main projects (P1 and P2). They are compiled in separated
environments, generating *.exe different files, but they use the same source
code allocated into a module (M1), that contains some functionalities like
file system, file transfer, etc.

We have also one library (L1) with 80% of source code equivalent of P1, and
it is compiled separated from P1, generating a L1.dll file.

The library L1 is used by three other application projects (A1, A2 and A3). 

So, three main situations:
1) When source code from P1 changes module M1, the P2 must have access to
it, and vice-versa. 
2) When source code from P1 changes shared code from L1, the L1 source code
must be actualized, and vice-versa.   
3) When L1.dll changes, A1, A2 and A3 should automatically start to use the
new L1 created.

I'm still a bit lost here how to share the codes into SVN. I think I may
create one repository to each one (P1, P2, M1, L1, A1, A2 and A3). The
problem is doing all svn commands for each one. 

For example, If I will change L1, I must to check out P1 and M1 to compile
it. Then, after changes, I must commit P1, M1 and L1, for source code and
commit the L1.dll file for A1, A2 and A3. It's unlikelly doing this

In other hand, I also think it's unlikelly to create only one repository for
all these projects.  
Finally, our system is a bit more complex than it, but the main structure is

Thanks again for your suggestions.

Okay, so there is a component (a library) that is shared between 
different projects, right? Or is it that you check in the compiled .DLLs 
or .LIBs separately to the source code?

This question is very important because of the different implications 
and strategies for approaching it. Reading the rest of your mail also 
doesn't make it clear, so it is impossible to give you proper advise 
without you answering that part first.

Note that what Peter suggested mostly deals with how to share the 
content between different projects using it and not so much with how to 
store it. In any case, svn:externals are a good tool but they are not 
always the right one.
