$NetBSD: TODO,v 1.5 2000/07/07 21:51:38 jhawk Exp $
|
|
|
|
In rough order.
|
|
|
|
Bugs to be fixed:
|
|
|
|
done command history sometimes gets slightly confused
|
|
|
|
2. uvm_fault()s can loop infinitely (kern/10016)
|
|
|
|
3. examine /m (hex + character dump) doesn't work.
|
|
|
|
4. "dot", "next", and "last" are not set properly and are usually
|
|
the same.
|
|
|
|
5. The vax port supporst decimal pids in "kill", etc. This should be
|
|
MI or not exist at all.
|
|
|
|
6. double-quote delimitted strings don't work in "print", nor do
|
|
multiple arguments (like the manpage says)
|
|
|
|
Features to be implemented:
|
|
|
|
1. Have "ps" print pids with a 0t prefix to reduce radix
|
|
confusion. This is very ugly...needs thought.
|
|
|
|
done "set" should display the old value as "write" does.
|
|
|
|
3. Support 64-bit longs in "write". /L or /q? both? long versus quad?
|
|
|
|
4. Note only some radixes are supported.
|
|
|
|
5. Allow a mechanism for DDB to not fail under X (on the i386).
|
|
Probably just skip DDB in such cases.
|
|
|
|
6. Enable DDB in GENERIC on all architectures not starved for
|
|
space.
|
|
|
|
7. Numbers starting with [a-f] should work, but symbols
|
|
of the same name should have priority.
|
|
|
|
8. Implement the unimplemented C operators, especially bitwise-OR (|).
|
|
|
|
9. "cond" -- conditionally execute a specified command on a breakpoint.
|
|
from Mach.
|
|
|
|
10. macros ("macro", "dmacro", "show macro"). from Mach.
|
|
|
|
11. !! command repitition (mostly unnecessary, just for consistency).
|
|
from Mach.
|
|
|
|
12. "continue" should honor _count as a number of breakpoints to ignore,
|
|
just as ",5:c" ignores 5 breakpoints in adb.
|
|
|
|
13. There should be a "step over" command (like :e in adb) that sets
|
|
a breakpoint at the next instruction if the current instruction
|
|
is a call (or jump?).
|
|
|
|
14. Specification of up to 4 ASCII chars as a 32-bit number
|
|
in an expression, like ' in adb:
|
|
'cccc' ASCII value of up to 4 characters.
|
|
I'm not sure what character to use for this, if the single-quote
|
|
is used for ditto, and the double-quote for strings in "print".
|
|
|
|
15. Add crossreference of gdb/ddb commands to manpage. i.e.
|
|
ddb "next" ~= gdb "finish".
|
|
|
|
16. Correct "ditto" to be a single-quote? Or something else?
|
|
|
|
17. option? To not lose system time when in ddb [reset clock on exit?]
|
|
|
|
18. Consider an XSERVER_DDB option [is it worth it?]
|
|
|
|
19. Eliminate vestigal DDB-specific kprintf() format specifiers
|
|
|
|
20. Figure out what's up with "ed_style"
|
|
|
|
21. Some sort of "immediate" step-in, step-over keybindings, like [
|
|
and ] in kadb (but not in adb):
|
|
[ Like :e in adb(1), but requires only one keys-
|
|
troke and no RETURN character.
|
|
|
|
] Like :s in adb(1), but requires only one keys-
|
|
troke and no RETURN character.
|
|
Does this make people queasy?
|
|
|
|
22. "search" should display useful output (by default? with /v?)
|
|
indicating success/failure rather than simply setting "dot".
|
|
Perhaps verbose by default unless called from a macro (ugh?).
|
|
|
|
23. kern/9544, some symbolic representation of boot flags
|
|
suitable for documentation (esp. for RB_NOSYNC).
|
|
|
|
24. Soren requests in-band symbol table storage for ddb.
|
|
"dbsym"? Needs investigation/thought.
|
|
|
|
25. Support multiple address spaces (e.g. io space).
|
|
Suggested by eeh in <Pine.NEB.4.21.0005250944210.25299-100000@ehorvath>
|
|
|
|
26. Expand help to provide usage/synopsis per-command.
|
|
|
|
27. Ensure MD commands have consistent names and factor out
|
|
common code.
|
|
|
|
28. Some way to track symbol table failures, since the message buffer
|
|
isn't available when we detect them.
