this change
- makes panic() variadic, doing full printf() formatting -
no more NO_NUM, and no more separate printf() statements
needed to print extra info (or something in hex) before panicing
- unifies panic() - same panic() name and usage for everyone -
vm, kernel and rest have different names/syntax currently
in order to implement their own luxuries, but no longer
- throws out the 1st argument, to make source less noisy.
the panic() in syslib retrieves the server name from the kernel
so it should be clear enough who is panicing; e.g.
panic("sigaction failed: %d", errno);
looks like:
at_wini(73130): panic: sigaction failed: 0
syslib:panic.c: stacktrace: 0x74dc 0x2025 0x100a
- throws out report() - printf() is more convenient and powerful
- harmonizes/fixes the use of panic() - there were a few places
that used printf-style formatting (didn't work) and newlines
(messes up the formatting) in panic()
- throws out a few per-server panic() functions
- cleans up a tie-in of tty with panic()
merging printf() and panic() statements to be done incrementally.
Test Program for Safecopy with or without COW How to run ========== Test safecopy with COW: 1. Set USE_COW_SAFECOPY to 1 in /usr/src/kernel/system/do_safecopy.c 2. Type `make run` to prepare and run test. 3. When done testing, type `make clean` to clean up. Test safecopy without COW: 1. Set USE_COW_SAFECOPY to 0 in /usr/src/kernel/system/do_safecopy.c 2. Type `make run` to prepare and run test. 3. When done testing, type `make clean` to clean up. If you want to modify the test buffer size: 1. Modify TEST_PAGE_NUM in inc.h 2. Modify TEST_PAGE_SHIFT in inc.h
