Eelco Dolstra	e25fad691a	* Move addTempRoot() to the store API, and add another function ... syncWithGC() to allow clients to register GC roots without needing write access to the global roots directory or the GC lock.	2006-12-02 16:41:36 +00:00
Eelco Dolstra	a824d58b56	* Merge addToStore and addToStoreFixed. ... * addToStore now adds unconditionally, it doesn't use readOnlyMode. Read-only operation is up to the caller (who can call computeStorePathForPath).	2006-12-01 20:51:18 +00:00
Eelco Dolstra	0565b5f2b3	* More remote operations. ... * Added new operation hasSubstitutes(), which is more efficient than querySubstitutes().size() > 0.	2006-11-30 22:43:55 +00:00
Eelco Dolstra	765bdfe542	* When NIX_REMOTE is set to "slave", fork off nix-worker in slave ... mode. Presumably nix-worker would be setuid to the Nix store user. The worker performs all operations on the Nix store and database, so the caller can be completely unprivileged. This is already much more secure than the old setuid scheme, since the worker doesn't need to do Nix expression evaluation and so on. Most importantly, this means that it doesn't need to access any user files, with all resulting security risks; it only performs pure store operations. Once this works, it is easy to move to a daemon model that forks off a worker for connections established through a Unix domain socket. That would be even more secure.	2006-11-30 19:54:43 +00:00
