Hi, I've been working in what I guess is 'classical' perforce with just single depots and want to begin using streams.  I can see a benefit to this; however, I'm having some understanding troubles I believe and want to see if my implementation will not run into serious problems in the long run.

What I have typically been doing for a client/server solution is separating these two spaces as two depots and would like to combine this in future projects to a single depot having some depth in the depot for each space. e.g.:

-  //depot/client/...
     -  //depot/client/main/...
     -  //depot/client/dev1.0/...
     -  //depot/client/dev1.1/...
     -  //depot/client/rel1.0/...
-  //depot/server/...
     -  //depot/server/main/...
     -  //depot/server/dev1.0/...

I also want to start using DVCS for my local workstation(s), as I have been working with it over the past week and find it handy. On my local workstation, I will keep projects in a relatively flat hierarchy. e.g.:

- D:\Projects\Contract01\...
    - D:\Projects\Contract01\App\...
    - D:\Projects\Contract01\Server\...

In this, ContractXX will relate to a specific company which gets a dedicated depot on the server.  With DVCS, I can initialize a personal server in each sub-folder of the ContractXX hierarchy, and map this to its' related depth in the depot  (the depot stream has been configured with a depth of 2).  e.g.:

Client01 has a mobile app and server, of which both have a release, and ongoing development, with remote mappings of something like:

(dev1.0 remote mapping)
DepotMap:  //stream/dev1.0/...  //Client01/ClientApp/dev1.0/...

(dev1.1 remote mapping)
DepotMap:  //stream/dev1.1/...  //Client01/ClientApp/dev1.1/...

(mainline remote mapping)
DepotMap: //stream/main/...  //Client01/ClientApp/main/...

With DVCS I can easily switch streams locally.. it's kinda awesome.  And when I'm ready to push.. I just select which stream I want to sync with server based on my remote mappings and push.

The strange thing I've noticed though, if I use P4V to connect to the server like I would have traditionally done.  The depot and level 1 depth streams show up as I would expect (with the wave icon), but the level 2 (such as main, dev1.1, and dev1.0) just show up as traditional folders.  Which is ok, and I suppose good in some ways I can think of some benefits to that.

I believe (and have not tested it) that with DVCS, it is probably not a as much an issue as when working with it in personal server mode, the streams (main, dev, rel) all work as expected.

Am I being too concerned about the folders not being designated as actually streams for dev, main, and rel and this is how it is suppose to be as depth 1 is clearly a stream?

oh I failed to mention I'm using these versions for server (2017.1/1511680) and p4v client (2017.2/1518788)

ok, so after a bit of testing a few ideas I can see some things that could be a problem I suppose.

If I change my remote mapping(s) to just a single mapping say "//Client01/ClientApp/..."  only the latest revisions from my local 'personal' perforce will be able to be pushed.  Basically making the remote server only a mainline repository with only the latest revision (and history) of my pushes from either my local 'mainline' or 'dev1.0' streams.

I could keep a track of the local main/dev streams by extended the remote mapping, but this isn't what I imagined it should be.  I figured that it would be able to determine that I was trying to create functional streams on both local and remote servers.  Doesn't seem to be that way.

How do I do this then?  Create a stream depot on the server, then be able to create a local server with streams to work with it?

Do I need to first create all streams with P4V against the remote server, then use the local personal server somehow.  I'm not seeing this though.

If you want to check that the items showing up as folders in P4V are in fact streams, you can run:
  p4 streams

from within the working directory of the DVCS server.

If they are indeed streams, there may be a UI issue in P4V.

If your company has support I suggest contacting 'support@perforce.com', so a P4V specialist can take a
look at this.

To add to this - any chance we could get the wave icon added to the final dir in stream depth? For example, if you have stream depot with a depth of 3 (//stream-depot/1/2/3) the wave icon shows up on dir 1, not dir 3. It would be really beneficial to our end users if they saw the wave icon on dir 3 so they know that whole path is the path they need to create clients from that stream etc.
