ddb: enable the use of ^C and ^S/^Q This lets one interrupt DDB's output, which is useful if paging is disabled and the output device is slow. This follows a previous implementation in svn r311952 / git 5fddef79998678d256ba30316353393b4d8ebb32 which was reverted because it broke DDB type-ahead. Now, try this again, but with a 512-byte type-ahead buffer. While there is buffer space, control input is handled and non-control input is buffered. When the buffer is exhausted, the default is to print a warning and drop further non-control input in order to continue handling control input. sysctl debug.ddb.prioritize_control_input can be set to 0 to instead preserve all input but lose immediate handling of control input. This could for example effect pasting of a large script into the ddb console.

Fixed loss of whitespace suppression at ends of lines. Whitespace suppression is only needed at ends of lines, but rev.1.32 forced it off precisely there. The --More-- prompt is now cleared by explicitly forcing out the whitespace in "\r \r". It might be better to use the line editor's clearing functions, but these are currently static and not much different.

Fixed formatting of printing of command tables. WIth the default max output width of 79, only 6 columns of width 12 each fit, but 7 columns were printed. The fix is to pass the width of the next output to db_end_line() and not assume there that this width is always 1. Related unfixed bugs: - 1 character is wasted for a space after the last column - suppression of trailing spaces used to limit the misformatting, but seems to have been lost - in db_examine(), the width of the next output is not know and is still assumed to be 1.

Simplify the pager support in DDB. Allowing different db commands to install custom pager functions didn't actually happen in practice (they all just used the simple pager and passed in a local quit pointer). So, just hardcode the simple pager as the only pager and make it set a global db_pager_quit flag that db commands can check when the user hits 'q' (or a suitable variant) at the pager prompt. Also, now that it's easy to do so, enable paging by default for all ddb commands. Any command that wishes to honor the quit flag can do so by checking db_pager_quit. Note that the pager can also be effectively disabled by setting $lines to 0. Other fixes: - 'show idt' on i386 and pc98 now actually checks the quit flag and terminates early. - 'show intr' now actually checks the quit flag and terminates early.

- Call db_setup_paging() for traceall. - Make it so one can't call db_setup_paging() if it has already been called before. traceall needs this, or else the db_setup_paging() call from db_trace_thread() will reset the printed line number, and override its argument. This is not perfect for traceall, because even if one presses 'q' while in the middle of printing a backtrace it will finish printing the backtrace before exiting, as db_trace_thread() won't be notified it should stop, but it is hard to do better without reworking the pager interface a lot more.

- Change the ddb paging "support" to use a variable (db_lines_per_page) to control the number of lines per page rather than a constant. The variable can be examined and changed in ddb as '$lines'. Setting the variable to 0 will effectively turn off paging. - Change db_putchar() to force out pending whitespace before outputting newlines and carriage returns so that one can rub out content on the current line via '\r \r' type strings. - Change the simple pager to rub out the --More-- prompt explicitly when the routine exits. - Add some aliases to the simple pager to make it more compatible with more(1): 'e' and 'j' do a single line. 'd' does half a page, and 'f' does a full page. MFC after: 1 month Inspired by: kris

Mega update for the KDB framework: turn DDB into a KDB backend. Most of the changes are a direct result of adding thread awareness. Typically, DDB_REGS is gone. All registers are taken from the trapframe and backtraces use the PCB based contexts. DDB_REGS was defined to be a trapframe on all platforms anyway. Thread awareness introduces the following new commands: thread X switch to thread X (where X is the TID), show threads list all threads. The backtrace code has been made more flexible so that one can create backtraces for any thread by giving the thread ID as an argument to trace. With this change, ia64 has support for breakpoints.

This change brings us inline with various other BSD versions. Driver writers may like to use (__FreeBSD_version == 300003) to detect this change. The prototype FreeBSD/alpha machdep will follow in a couple of days time.

Change all #includes to follow the current Berkeley style. Some of these ``changes'' are actually not changes at all, but CVS sometimes has trouble telling the difference. This also includes support for second-directory compiles. This is not quite complete yet, as `config' doesn't yet do the right thing. You can still make it work trivially, however, by doing the following: rm /sys/compile mkdir /usr/obj/sys/compile ln -s M-. /sys/compile cd /sys/i386/conf config MYKERNEL cd ../../compile/MYKERNEL ln -s /sys @ rm machine ln -s @/i386/include machine make depend make

Make everything compile with -Wtraditional. Make it easier to distribute a binary link-kit. Make all non-optional options (pagers, procfs) standard, and update LINT to reflect new symtab requirements. NB: -Wtraditional will henceforth be forgotten. This editing pass was primarily intended to detect any constructions where the old code might have been relying on traditional C semantics or syntax. These were all fixed, and the result of fixing some of them means that -Wall is now a realistic possibility within a few weeks.
