* Use strchr() and strrchr().Ed Schouten2012-01-021-1/+1
| | | | | | | | | | | It seems strchr() and strrchr() are used more often than index() and rindex(). Therefore, simply migrate all kernel code to use it. For the XFS code, remove an empty line to make the code identical to the code in the Linux kernel. Notes: svn path=/head/; revision=229272

Otherwise, there are cases where garbage may end up in the command history due to a lack of a nul terminator, or input may end up without room for a newline.

Otherwise, we may overshoot, overwriting a bit of the previous line and failing to fully overwrite the current line.

A new DDB command, "capture", is added, which accepts arguments "on", "off", "reset", and "status". A new DDB sysctl tree, debug.ddb.capture, is added, which can be used to resize the capture buffer and extract buffer contents. MFC after: 3 months Notes: svn path=/head/; revision=174910

* Add a new mechanism, cndbctl(), to tell the console driver thatKazutaka YOKOTA2000-01-111-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | ddb is entered. Don't refer to `in_Debugger' to see if we are in the debugger. (The variable used to be static in Debugger() and wasn't updated if ddb is entered via traps and panic anyway.) - Don't refer to `in_Debugger'. - Add `db_active' to i386/i386/db_interface.d (as in alpha/alpha/db_interface.c). - Remove cnpollc() stub from ddb/db_input.c. - Add the dbctl function to syscons, pcvt, and sio. (The function for pcvt and sio is noop at the moment.) Jointly developed by: bde and me (The final version was tweaked by me and not reviewed by bde. Thus, if there is any error in this commit, that is entirely of mine, not his.) Some changes were obtained from: NetBSD Notes: svn path=/head/; revision=55823

* The following patch will remove a hack introduced inKazutaka YOKOTA1999-07-141-13/+1
| | | | | | | | | | /sys/ddb/db_input.c rev 1.19 to recognize syscons's cursor keycodes. It is unnecessary now that scgetc() in syscons returns the escape sequence for the cursor keys rather than their raw, internal key codes. Notes: svn path=/head/; revision=48810
* Some fixes from John Hood:John Dyson1997-12-051-2/+1
| | | | | | | | | | | 1) Fix the initialization of malloc structure that changed due to perf opt. 2) Remove unneeded include. 3) An initialization assert added to malloc. Submitted by: John Hood <cgull@smoke.marlboro.vt.us> Notes: svn path=/head/; revision=31549

* Don't try to do anything with the input history if MALLOC() for the bufferMike Smith1997-11-071-2/+2

* Minor hack to also allow for syscons's "interesting" arrow keys.Joerg Wunsch1997-08-171-1/+13
| | | | | | | | I'm using "#if __i386__ && __FreeBSD__" to check for a ``potentially syscons-relevant environment''. Hope that's ok... Notes: svn path=/head/; revision=28330

* Make the long-awaited change from $Id$ to $FreeBSD$Jordan K. Hubbard1997-01-141-1/+1
| | | | | | | | | | | This will make a number of things easier in the future, as well as (finally!) avoiding the Id-smashing problem which has plagued developers for so long. Boy, I'm glad we're not using sup anymore. This update would have been insane otherwise. Notes: svn path=/head/; revision=21673

* Finally implement a simple commandline history in DDB.Joerg Wunsch1996-08-101-2/+71
| | | | | | | | | | | Emacs-style line editing has already been there (did anybody ever notice this? :), so i `only' had to add ^P and ^N. The approach is fairly minimalistic, with the advantage of keeping the bloat as small as 864 bytes of .text and 16 bytes of .bss, plus 10*120 bytes malloc'ed history buffer at the first use.

| | | | | | | | | | | | | to get the prototypes. Changed some `int's to `boolean_t's. boolean_t's are ints so they are hard to distinguish from ints. Converted function headers to old-style. ddb is written in K&R1 C except where we broke it. Notes: svn path=/head/; revision=12473

* Fix up some sloppy coding practices:Garrett Wollman1994-08-181-7/+7
| | | | | | | | | | | | | | | - Delete redundant declarations. - Add -Wredundant-declarations to Makefile.i386 so they don't come back. - Delete sloppy COMMON-style declarations of uninitialized data in header files. - Add a few prototypes. - Clean up warnings resulting from the above. NB: ioconf.c will still generate a redundant-declaration warning, which is unavoidable unless somebody volunteers to make `config' smarter. Notes: svn path=/head/; revision=2112
* Change all #includes to follow the current Berkeley style. Some of theseGarrett Wollman1994-08-131-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | ``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 Notes: svn path=/head/; revision=2056

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. Notes: svn path=/head/; revision=879
