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. Should your needs expand to the point where more than one person needs to get at your information at the same time, you can always convert your Helix Personal Server to a Helix Workgroup Server by purchasing additional seats.Perforce is a commercial, proprietary revision control system developed by Perforce Software, Inc. Log in to the QSA Web Store to purchase your Helix Client/Server Toolkit. The Helix Client/Server Toolkit is priced according to concurrent access (CA). Helix Server keeps all your information in one location while you move around, working on a laptop, a machine at work, while your information is stored at home. This means that a Helix Client/Server Toolkit workgroup user can access his or her Helix Collection from anywhere in the house or office to anywhere in the world. The Client application can be distributed without restriction, allowing access from any machine with internet access.ĭedicated server hardware is not required. Helix Server is licensed for simultaneous access that is, according to the number of Clients that will be accessing the collection at any given time. Even so, Helix Server features built-in record locking, making sure two users can not edit the same record at the same time. Helix Client/Server Toolkit for macOS is a Helix Server that provides unlimited access to a single user.Ĭomprised of Helix Server and Helix Client, these products allow any Helix Collection that is set up to operate in User Mode to run on a variety of network configurations.ĭesigned for workgroups from 2 to 200, the Client/Server model guarantees that every user has simultaneous access to the data, unlike file sharing, where each user must wait for the others to finish their work before even being able to see the data, no less edit it.
