After 'p4 init -C0 -n', the local repo should already have a stream depot named 'stream' and a mainline stream named //stream/main.

==============================================================================
Scenario 1 setup: Configure //stream/main with 'isolate Version'.
The mainline stream generated by p4 init starts with ordinary shared stream paths.
This repro edits only //stream/main and adds the SDP-style isolated Version path:
Paths:
share ...
isolate Version
Modified //stream/main stream spec:

Scenario 2: Create descendant streams after main already has 'isolate Version'.
Creating //stream/dev as a development child of //stream/main.
Stream: //stream/dev

Creating //stream/r26.1 as a release child of //stream/main.
This intentionally relies on the server's release-stream defaults rather than manually creating a noinherit stream depot or custom depot spec.
Stream: //stream/r26.1

Stream //stream/main mainline none '//stream/main'
Stream //stream/r26.1 release //stream/main 'r26.1'
==============================================================================
Scenario 3: Capture stream specs and generated views for later inspection.
The generated view output is intentionally verbose. It is often the most useful evidence when discussing stream behavior with someone who knows ViewGen internals.

==============================================================================
Scenario 4: Create one workspace per stream.
Using separate workspaces makes the file operations easier to read in the resulting log.
==============================================================================
Scenario 5: Add a different Version file in every stream.
The theory is that each Version file lives in its own stream forever and is not subject to normal Merge Down / Copy Up flow.
Adding Version in //stream/main.
Executing command: p4 add Version
//stream/main/Version#1 - opened for add
Executing command: p4 submit -d Add-main-Version
Submitting change 5.
Locking 1 files ...
add //stream/main/Version#1
Change 5 submitted.
Adding Version in stream dev.
Executing command: p4 client -s -S //stream/dev
Client ttyler-dvcs-1785246949 switched.
Executing command: p4 sync
//stream/main/Version#1 - deleted as /tmp/repro/Version
Executing command: p4 add Version
//stream/dev/Version#1 - opened for add
Executing command: p4 submit -d Add-dev-Version
Submitting change 6.
Locking 1 files ...
add //stream/dev/Version#1
Change 6 submitted.
Adding Version in stream dev_rebrand.
Executing command: p4 client -s -S //stream/dev_rebrand
Client ttyler-dvcs-1785246949 switched.
Executing command: p4 sync
//stream/dev/Version#1 - deleted as /tmp/repro/Version
Executing command: p4 add Version
//stream/dev_rebrand/Version#1 - opened for add
Executing command: p4 submit -d Add-dev_rebrand-Version
Submitting change 7.
Locking 1 files ...
add //stream/dev_rebrand/Version#1
Change 7 submitted.
Adding Version in stream r26.1.
Executing command: p4 client -s -S //stream/r26.1
Client ttyler-dvcs-1785246949 switched.
Executing command: p4 sync
//stream/dev_rebrand/Version#1 - deleted as /tmp/repro/Version
Executing command: p4 add Version
//stream/r26.1/Version#1 - opened for add
Executing command: p4 submit -d Add-r26.1-Version
Submitting change 8.
Locking 1 files ...
add //stream/r26.1/Version#1
Change 8 submitted.
==============================================================================
Scenario 6: Add ordinary shared files that should be proposed by merge previews.
To avoid a false PASS, this repro also creates ordinary shared files. The preview tests should show these ordinary files as candidates while not showing Version.
Adding SharedFromMain.txt in //stream/main.
Executing command: p4 client -s -S //stream/main
Client ttyler-dvcs-1785246949 switched.
Executing command: p4 sync
//stream/main/Version#1 - replacing /tmp/repro/Version
Executing command: p4 add SharedFromMain.txt
//stream/main/SharedFromMain.txt#1 - opened for add
Executing command: p4 submit -d Add-shared-file-from-main
Submitting change 9.
Locking 1 files ...
add //stream/main/SharedFromMain.txt#1
Change 9 submitted.
Adding SharedFromDev.txt in //stream/dev.
Executing command: p4 client -s -S //stream/dev
Client ttyler-dvcs-1785246949 switched.
Executing command: p4 sync
//stream/main/SharedFromMain.txt#1 - deleted as /tmp/repro/SharedFromMain.txt
//stream/dev/Version#1 - replacing /tmp/repro/Version
Executing command: p4 add SharedFromDev.txt
//stream/dev/SharedFromDev.txt#1 - opened for add
Executing command: p4 submit -d Add-shared-file-from-dev
Submitting change 10.
Locking 1 files ...
add //stream/dev/SharedFromDev.txt#1
Change 10 submitted.
==============================================================================
Scenario 7: Preview merges and look for Version.
A successful result is not merely that merge previews are empty.
A successful result is that ordinary shared files are proposed, while Version is not proposed.
Preview merge from parent //stream/main into child //stream/dev.
Expected: SharedFromMain.txt should appear; Version should not appear.
Executing command: p4 client -s -S //stream/dev
Client ttyler-dvcs-1785246949 not changed.
Executing command: p4 sync
File(s) up-to-date.
//stream/dev/SharedFromMain.txt#1 - sync/delete from //stream/main/SharedFromMain.txt#1
... must resolve branch from //stream/main/SharedFromMain.txt#1
Preview merge from parent //stream/dev into grandchild //stream/dev_rebrand.
Expected: SharedFromDev.txt should appear; Version should not appear.
Executing command: p4 client -s -S //stream/dev_rebrand
Client ttyler-dvcs-1785246949 switched.
Executing command: p4 sync
//stream/dev/SharedFromDev.txt#1 - deleted as /tmp/repro/SharedFromDev.txt
//stream/dev_rebrand/Version#1 - replacing /tmp/repro/Version
//stream/dev_rebrand/SharedFromDev.txt#1 - sync/delete from //stream/dev/SharedFromDev.txt#1
... must resolve branch from //stream/dev/SharedFromDev.txt#1
Preview merge from parent //stream/main into release stream //stream/r26.1.
Expected: SharedFromMain.txt should appear; Version should not appear.
Executing command: p4 client -s -S //stream/r26.1
Client ttyler-dvcs-1785246949 switched.
Executing command: p4 sync
//stream/r26.1/Version#1 - replacing /tmp/repro/Version
//stream/r26.1/SharedFromMain.txt#1 - branch/sync from //stream/main/SharedFromMain.txt#1
==============================================================================
Scenario 8: Additional inspection commands.
These commands are informational. They make the log more useful if this repro is later sent to someone else for review.
Executing command: p4 files //stream/...
//stream/dev/SharedFromDev.txt#1 - add change 10 (text)
//stream/dev/Version#1 - add change 6 (text)
//stream/dev_rebrand/Version#1 - add change 7 (text)
//stream/main/SharedFromMain.txt#1 - add change 9 (text)
//stream/main/Version#1 - add change 5 (text)
//stream/r26.1/Version#1 - add change 8 (text)
Executing command: p4 interchanges //stream/main //stream/dev
//stream/main - all revision(s) already integrated.
Executing command: p4 interchanges //stream/dev //stream/dev_rebrand
//stream/dev - all revision(s) already integrated.
Executing command: p4 interchanges //stream/main //stream/r26.1
//stream/main - all revision(s) already integrated.
==============================================================================
The Result:
Yay!
The observed behavior supports the theory being tested:
isolate Version
defined only in //stream/main was sufficient for the descendant streams created after that setting was present.
The merge previews proposed ordinary shared files, proving the merge previews were meaningful, but did not propose Version.
This supports the SDP design assumption that Version can be isolated once in main rather than redundantly isolated in every descendant development stream.
For release streams, this repro also checks the practical behavior of a release stream created after main already had the isolated path. Existing noinherit release streams created before the path change should still be reviewed separately.
