assar 8422fba5ab repair command-line parsing so that an error is generated if no pid or
program is given (or input file for ktruss)

simonb 0f134bcc0b Don't assume pipes are implemented as sockets -- don't call setsockopt()
on the pipe descriptors.

matt fcd0fb118f Make gcc 2.96 (and maybe earlier) happier. Include <stdlib.h>,<string.>,
etc. as appropriate to get exit,srncmp,abs,abort,etc.
Add -I${.CURDIR} to a few Makefiles

sommerfeld d4ddc11a83 Two tweaks:
- For cleaner subprocess traces, malloc something before
spawning, so the syscalls malloc does while initializing don't gunk up
the trace.
	- Increase pipe buffer sizes.

itohy 0af9894f2f [ktruss] Use fork(2), not vfork(2).
The child process of do_ktrace() does return and the stack is
changed by another function call (execvp()).
By using vfork() (my previous change), the execution of the parent
process resumes on the modified stack.  Oops.
We could use vfork() carefully, but for now use fork().

Problem reported and investigated by Ethan Solomita <ethan@geocast.com>.
Thanks.

jdolecek 0cdfde1cbc DTRT vs setemul() (for ktruss, similar to kdump.c) 2000-04-10 09:32:03 +00:00

itohy 2f4c0d5e74 Make ktrace(1) not affect interactions between processes.
Following examples show the cases.

    % ktrace -f - false >/dev/null && echo wrong
    wrong
    % ktrace -f - -i /usr/sbin/update >/dev/null
    (does not return to command line)

That is, back out last change and restore the roles of parent/child for
ktrace(1).  The ktruss(1) stuff still remains.
Yes, ktruss(1) has the problems.  Better implementation is expected.

darrenr c1f203f8b5 Change behaviour from running the command as the parent and ktrace/ktruss as
the child to be ktruss/ktrace is the parent.  This fixes a problem with ktruss
where the prompt would be returned in the middle of output.

itohy 99624b0b6d Fix fowllowing problems:
1. If fork()ing, the program is executed twice.
2. If the ktruss(1) output is bufferd, the final output is not flushed
   (because it is executing).

    % ktrace -f - rm >/dev/null

kleink 3ed4fcf61e In userland, pull in <errno.h> instead of <sys/errno.h> for the declaration
of errno.
