pipes in the shell, though the semantics is a little different: The second command is invoked whenever the first command has written a complete line. The line is passed as last argument to the second command. The new command flag B_KDEBUG_PIPE_FINAL_RERUN causes the second command to be invoked again (with NULL argument) after the first command is done. * Added kprintf_unfiltered() and kputs_unfiltered() which bypass the pipe mechanism and directly print to the bluescreen/serial output. * Moved most commands from debug.cpp to the new debug_builtin_commands.cpp. * B_KDEBUG_DONT_PARSE_ARGUMENTS commands don't get an argument anymore, if it would consist of white space only. * Added new debugger command return value B_KDEBUG_ERROR, which indicates that executing the command failed. This return code will abort a complete pipe. * Since debugger commands can nest (i.e. one command can invoke another one) the setjmp()/longjmp() mechanism to restore the stack after a page fault in a command needs more than one jump buffer. * Added abort_debugger_command(), which longjmp()s out of the currently executed command. This will also abort the current pipe. * When pagination is enabled pressing "a" will abort the running command (as opposed to "q" which only disables the blue screen output, but lets the command continue). * Added debugger commands: - "grep" which can be used to filter output by pattern. Removed the "filter" command and the underlying mechanism that did that before. - "head" which prints only the first lines of output of another command. - "wc" counts lines, words, and characters of another command's output. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25744 a95241bf-73f2-0310-859d-f6bbb57e9c96 |
