19 * All code runs under the same UID but sensitive code paths are
20 * run in a separate process with tighter pledge(2) promises.
21 * Data is communicated between processes via imsg_flush(3) and imsg_read(3).
22 * This behaviour is transparent to users of the library.
24 * We generally transmit data in imsg buffers, split across several messages
25 * if necessary. File descriptors are used in cases where this is impractical,
26 * such as when accessing pack files or when transferring large blobs.
28 * We exec(2) after a fork(2). Parts of our library functionality are
29 * accessible via separate executables in a libexec directory.
