Phantom OS is anorthogonally persistentmanaged code general-purposeoperating system. It is based on a concept of persistentvirtual memory, and executesbytecode in avirtual machine. It is one of a few OSes not based on the classic concepts ofUnix-like systems. Phantom is based on the principle that "Everything is anobject", in contrast to theUnix-like approach of "Everything is a file".[1]
Phantom was founded byDmitry Zavalishin [ru][1] and is being developed mostly by Russian programmers. It isfree and open-source software (FOSS) released under aGNU Lesser General Public License (LGPL).
Managed code – Memory protection on object level, rather thanprocess level; absence ofpointer arithmetic in managed code avoids many problems that exist and occur in unmanaged code.[2]
Global address space – Inexpensiveinter-process communication (IPC).Single (flat) address space allows transfer of objects from one process (application) to another by transferring links to that object. Security is achieved by the absence of pointer arithmetic and the inability of an application to get linked to an object other than by calling a public method.[2]
Persistence – Application code does not see OS restarts and can live forever—this does not use the concept of a file and any variable or data structure can be stored forever and at the same time be available directly through a pointer. Contrary to hibernation, which is done in other OSs, persistence lies in the very core principles of the Phantom OS core. The implementation creates snapshots continuously and transparently to the applications maintaining consistent internal state without pausing applications.[1]
Two ways to migrate code are offered:[2]
As of October 2019[update], the system exists as an alpha version forx86IA-32 processors. Porting toARM architecture is underway (currently being tested, not yet ready for use) and porting toMIPS architecture andx86-64 (AMD64) has begun. Kernel operation has been demonstrated at the biggest Russian IT-conferences RIT 2011, ADD 2010,[3] CC 2010,[4] and 2009.
AGenode-based fork has been in development since 2020.[2]
