9. Federated Architecture for Distributed Teams
• Commit/Edge modes for server
• Local metadata with edge
services
• Submits propagated to commit
service
• Other commands execute locally

14. Sync Performance
• Sync Performance Increased
– Network window size optimization
– Transfer multiple times at a time – aka Parallel Sync

SERVER OPTIMIZATIONS

18. Sync Performance Results
• Network window size optimization
– 1/16th the amount of network round trips
• Parallel Sync
– 1/4th the amount of time
• Results of both
– Syncs up to 20 times faster
SERVER OPTIMIZATIONS

19. LDAP For User Authentication
• Perforce provides Authentication Trigger entry points for lookup into
third party user database (including LDAP)
• auth_check trigger works well, but ...
– Needs to be installed separately
– No standard (Python, Perl, C++ implementations)
– One more headache for administrators
• Most common request on P4Ideax:
– Perforce should provide built-in LDAP integration
SERVER OPTIMIZATIONS

20. Native LDAP support

21. Native LDAP support
• Increases Security
– Consistent Authentication and Authorization
• Simplifies Policy Management
– Access granted/revoked by LDAP group membership

23. Solution: External Index
P4 Search
SERVER OPTIMIZATIONS
store
search
Search engine indexes content
Stores it in its own database
Users search the index first
Index returns a depot path
Permissions applied to index
results
Returns results to user

24. P4Search
• File content
• P4 Metadata
• P4 attributes
• And the common
metadata if
desired

30. Streams
• Model the flow of change for
the entire product lifecycle
• Visual roadmap for users
• Remove the fear/overhead
of branching and merging
END USERS

31. Streams – 2014 Features
• Streams allows “import”
paths to include
components from one
Stream into another.
– Import is by reference (not a
END USERS
copy)
– Import path is Read Only

32. Streams – 2014 Features
Top Requests of Streams to
facilitate managing Components
with Streams:
– “I want to lock an import a
specific version of my
component.”
– “I want to submit changes to a
referenced component.”
• Makes managing components
END USERS
simpler

33. Streams – Frozen Imports
Paths:
import import/... //depot/import/…@1000
• Freezes the import path (component) at a point in time.
• p4 sync import/…#head behaves like p4 sync import/…@1000
END USERS

34. Streams – Writeable Imports
Paths:
import+ import/... //depot/import/…
• Functions like standard import, enabling you to map a path or
Component from outside the stream.
• But unlike a standard import path, you can submit changes to the
files in an import+ path.
END USERS

35. Streams – 2014 Features
• Frozen Imports and Writeable
Imports
– Simplifies the management of
Components within a Stream
