1$NetBSD: TODO,v 1.11.6.5 2005/11/10 14:03:00 skrll Exp $ 2 3In rough order. 4 5Bugs to be fixed: 6 7done command history sometimes gets slightly confused 8 92. uvm_fault()s can loop infinitely (kern/10016) 10 11done examine /m (hex + character dump) doesn't work. 12 134. "dot", "next", and "last" are not set properly and are usually 14 the same. 15 165. The vax port supports decimal pids in "trace", etc. This should be 17 MI or not exist at all. 18 196. double-quote delimited strings don't work in "print", nor do 20 multiple arguments (like the manpage says) 21 22Features to be implemented: 23 24dead Have "ps" print pids with a 0t prefix to reduce radix 25 confusion. This is very ugly...needs thought. 26 27done "set" should display the old value as "write" does. 28 293. Support 64-bit longs in "write". /L or /q? both? long versus quad? 30 314. Note only some radixes are supported. 32 335. Allow a mechanism for DDB to not fail under X (on the i386). 34 Probably just skip DDB in such cases. 35 366. Enable DDB in GENERIC on all architectures not starved for 37 space. 38 39done Numbers starting with [a-f] should work, but symbols 40 of the same name should have priority. 41 428. Implement the unimplemented C operators, especially bitwise-OR (|). 43 449. "cond" -- conditionally execute a specified command on a breakpoint. 45 from Mach. 46 4710. macros ("macro", "dmacro", "show macro"). from Mach. 48 4911. !! command repitition (mostly unnecessary, just for consistency). 50 from Mach. 51 5212. "continue" should honor _count as a number of breakpoints to ignore, 53 just as ",5:c" ignores 5 breakpoints in adb. 54 5513. 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 5914. 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 6515. Add crossreference of gdb/ddb commands to manpage. i.e. 66 ddb "next" ~= gdb "finish". 67 6816. Correct "ditto" to be a single-quote? Or something else? 69 7017. option? To not lose system time when in ddb [reset clock on exit?] 71 7218. Consider an XSERVER_DDB option [is it worth it?] 73 7419. Eliminate vestigal DDB-specific kprintf() format specifiers 75 7620. Figure out what's up with "ed_style" 77 7821. 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. 82 83 ] Like :s in adb(1), but requires only one keys- 84 troke and no RETURN character. 85 Does this make people queasy? 86 8722. "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 9123. kern/9544, some symbolic representation of boot flags 92 suitable for documentation (esp. for RB_NOSYNC). 93 9424. Soren requests in-band symbol table storage for ddb. 95 "dbsym"? Needs investigation/thought. 96 9725. Support multiple address spaces (e.g. io space). 98 Suggested by eeh in <Pine.NEB.4.21.0005250944210.25299-100000@ehorvath> 99 10026. Expand help to provide usage/synopsis per-command. 101 10227. Ensure MD commands have consistent names and factor out 103 common code. 104 10528. Some way to track symbol table failures, since the message buffer 106 isn't available when we detect them. 107 10829. Make "workXX" variables work. 109 11030. Write ddb(9) to document how ports should implement the debugger, 111 and the canonical solution to some niggling annoying issues. 112 11331. Add support for cpus where sizeof(register_t) is not necessarily 114 the same as sizeof(void *). This is the case on SH5 using the 115 ILP32 ABI. On this CPU db_expr_t is, necessarily, 64-bits. 116 Unfortunately, in ILP32 mode, ddb will only display the low 32-bits 117 of any expression, including registers... 118 119done Add support for duplicating all ddb output to the message buffer for 120 those unlucky souls that don't have a serial console. 121 122
