I didn't think the sparse directories feature would make single file
checkouts possible, and its not really that which worries me. To be
honest, I think the sparse checkout setup (I have taken a look at the
nightly builds of SVN and TSVN now) is more than sufficient for myself.
I'm just thinking of possible issues that might confront me in migrating
my company from VSS to SVN. I'm speculating somewhat as I have only
briefly discussed this with the guy in charge of our VSS installation so
I don't have a full handle on what the use cases might be. However I am
sure that one thing they will point out is the inability to easily
cherry pick from the repository structure.
Because the VSS browser is tied (and I hate that it is in general) to a
particular directory, its easy to cherry pick directories you want and
it will build the required directory structure for you (if it doesn't
already exist). This can be important for large projects will that have
deepish trees and rely on the structure as part of the build system.
I just thought it would be a nice feature if you could have a browser
which showed you the full repository view that a working copy was
connected to and allowed you to pick which bits you want (even if its
only to the directory level) and it would build any parent directories
required. So far I don't see that this is possible, you have to manually
drill down the directory structure, updating till you get to the point
you want. Or am I mising something?
If this is simply something thatis deemed unecessary for most people
then I can understand that, maybe if I get time I will see if I can
implement it myself.
For now I will just keep playing and see if I have missed something.
Here is a simple example of what I am thinking "might" be wanted. I'm
not even suggesting this is a "good" structure for a project, or that
its one we use, its just trying to show my thinking.
User A wants to have the following structure
So far, teh way I see it the user must do the following:
1. checkout trunk/ to create wc (immediate children)
2. update src
3. update lib
4. update math
5. update apps
6. update alarm1
7. update platform
8. update arm7
9. update scripts
10. update build
11. update alarm1
Personally I think it would be easier if they could do the following:
1. checkout trunk/ to create wc (only this item)
2. Use WC browser and "update / checkout the following items"
By my reckoning thats 6 less operations, and is a lot easier for some
people to understand than having to update various directories till they
have what they want. I would see this as wrapping the sparse checkout
interface. So for example I would expect the operation of doing 2a)
would probably end up with top level being updating with immediates, and
same for src and lib.
