Perforce helix server setup1/26/2024 ![]() Revisions that are branches or copies of other revisions are virtual copies within the repository. The encoding used for text files in the repository is either ASCII or UTF-8, depending on Perforce server configuration. Text file revisions are stored as RCS deltas and binary file revisions are stored in their entirety. Versioned file content is stored in a master directory hierarchy whose top levels are called “depots”. Administrators must plan for disaster recovery by configuring database journaling and setting up regular checkpoints. A database that has been corrupted by hardware failure or other catastrophe can be recovered from the most recent journal and checkpoint. Checkpoints and journals are written as text files that can be compressed and offloaded. ![]() MD5 hashes of file content are stored in the database, however, and can be used to verify repository file integrity.ĭatabase tables are stored as binary files. File content itself is not stored in the database. Files are identified by namespace (i.e., by OS-neutral filenames). It stores system-related metadata (file state, file attributes, branching and merging history, changelists, change descriptions, users, groups, labels, etc.). The Perforce database is proprietary, preconfigured, and self-installed. Users submit changed files together in changelists, which are applied as atomic commits. A Git client can communicate with the Perforce server over SSH or HTTPS, and other Perforce clients communicate with the server via TCP/IP using a proprietary RPC and streaming protocol. Perforce supports both Git clients and clients that use Perforce’s own protocol. The Perforce server manages a central database and a master repository of file versions. Perforce is a commercial, proprietary revision control system developed by Perforce Software, Inc.
