Annotation of src/sys/ddb/TODO, Revision 1.10
1.10 ! simonb 1: $NetBSD: TODO,v 1.9 2002/01/05 01:48:10 jhawk Exp $
1.1 jhawk 2:
3: In rough order.
4:
5: Bugs to be fixed:
6:
1.3 jhawk 7: done command history sometimes gets slightly confused
1.1 jhawk 8:
9: 2. uvm_fault()s can loop infinitely (kern/10016)
10:
1.7 jmc 11: done examine /m (hex + character dump) doesn't work.
1.1 jhawk 12:
13: 4. "dot", "next", and "last" are not set properly and are usually
14: the same.
15:
1.7 jmc 16: 5. The vax port supports decimal pids in "kill", etc. This should be
1.1 jhawk 17: MI or not exist at all.
18:
19: 6. double-quote delimitted strings don't work in "print", nor do
20: multiple arguments (like the manpage says)
21:
22: Features to be implemented:
23:
24: 1. Have "ps" print pids with a 0t prefix to reduce radix
1.4 jhawk 25: confusion. This is very ugly...needs thought.
1.1 jhawk 26:
1.4 jhawk 27: done "set" should display the old value as "write" does.
1.1 jhawk 28:
29: 3. Support 64-bit longs in "write". /L or /q? both? long versus quad?
30:
31: 4. Note only some radixes are supported.
32:
33: 5. Allow a mechanism for DDB to not fail under X (on the i386).
1.10 ! simonb 34: Probably just skip DDB in such cases.
1.1 jhawk 35:
36: 6. Enable DDB in GENERIC on all architectures not starved for
37: space.
38:
1.6 eeh 39: done Numbers starting with [a-f] should work, but symbols
1.1 jhawk 40: of the same name should have priority.
41:
42: 8. Implement the unimplemented C operators, especially bitwise-OR (|).
43:
44: 9. "cond" -- conditionally execute a specified command on a breakpoint.
45: from Mach.
46:
47: 10. macros ("macro", "dmacro", "show macro"). from Mach.
48:
49: 11. !! command repitition (mostly unnecessary, just for consistency).
50: from Mach.
51:
52: 12. "continue" should honor _count as a number of breakpoints to ignore,
53: just as ",5:c" ignores 5 breakpoints in adb.
54:
55: 13. There should be a "step over" command (like :e in adb) that sets
56: a breakpoint at the next instruction if the current instruction
57: is a call (or jump?).
58:
59: 14. Specification of up to 4 ASCII chars as a 32-bit number
60: in an expression, like ' in adb:
61: 'cccc' ASCII value of up to 4 characters.
62: I'm not sure what character to use for this, if the single-quote
63: is used for ditto, and the double-quote for strings in "print".
64:
65: 15. Add crossreference of gdb/ddb commands to manpage. i.e.
66: ddb "next" ~= gdb "finish".
67:
68: 16. Correct "ditto" to be a single-quote? Or something else?
69:
70: 17. option? To not lose system time when in ddb [reset clock on exit?]
71:
72: 18. Consider an XSERVER_DDB option [is it worth it?]
73:
74: 19. Eliminate vestigal DDB-specific kprintf() format specifiers
75:
76: 20. Figure out what's up with "ed_style"
77:
78: 21. Some sort of "immediate" step-in, step-over keybindings, like [
79: and ] in kadb (but not in adb):
80: [ Like :e in adb(1), but requires only one keys-
81: troke and no RETURN character.
1.10 ! simonb 82:
1.1 jhawk 83: ] Like :s in adb(1), but requires only one keys-
84: troke and no RETURN character.
85: Does this make people queasy?
86:
87: 22. "search" should display useful output (by default? with /v?)
88: indicating success/failure rather than simply setting "dot".
89: Perhaps verbose by default unless called from a macro (ugh?).
90:
91: 23. kern/9544, some symbolic representation of boot flags
92: suitable for documentation (esp. for RB_NOSYNC).
93:
94: 24. Soren requests in-band symbol table storage for ddb.
95: "dbsym"? Needs investigation/thought.
96:
97: 25. Support multiple address spaces (e.g. io space).
98: Suggested by eeh in <Pine.NEB.4.21.0005250944210.25299-100000@ehorvath>
99:
100: 26. Expand help to provide usage/synopsis per-command.
101:
102: 27. Ensure MD commands have consistent names and factor out
103: common code.
1.5 jhawk 104:
105: 28. Some way to track symbol table failures, since the message buffer
106: isn't available when we detect them.
1.8 jhawk 107:
108: 29. Make "workXX" variables work.
1.9 jhawk 109:
110: 30. Write ddb(9) to document how ports should implement the debugger,
111: and the canonical solution to some niggling annoying issues.
