| Description | Too much Unix code is dangerously copied and not shared. There are lots of almost the same files: prot*.c lock*.c vm*.c Maybe others. |
| Analysis | Historically many Unixes were almost the same but not quite. In the 21st century those Unixes have either died, evolved into, or been replaced by Unixes that implement a common interface, usually some sort of POSIX interface or an evolution thereof. See what code can be shared across different unixes and share it. Use the platform code ix for implementations that are shared across more than one Unix-like operating system. 2007-03-09 DRJ: protix.c, protsgix.c now used on Intel Darwin and FreeBSD. protix.c now also used on Linux. protli.c removed. 2007-03-12 DRJ: lockix.c now used on Darwin and FreeBSD. lockfr.c removed. vmix.c now used on Darwin and FreeBSD. vmfr.c and vmxc.c removed. 2007-07-20 DRJ: vmix.c now used on Linux. vmli.c removed. |
