explorer b59a6a8b5f return 0.0 cpu usage for zombies. closes pr bin/2693. Perhaps this should
be fixed in exit, so p->p_pctcpu is cleared when the process exits.

jtc 33849ebec9 Add the asf command for absolute tape positioning.
Some cleanup of the remote tape interface, but a lot more is needed.
Ideally, we'd have a "rmt" library which provides a remote tape API
including open, read, write, close, and ioctl.  This is useful not
only for mt, but also for programs like tar, cpio, pax, backup and
restore.

christos beb57fb35d - Add function callback capability when variables are set.
- Add setvarsafe that returns an error instead of longjmp() to the
  error code.
1996-06-25 16:49:05 +00:00
christos cc31700a92 - Add getoptsreset to be used as a callback function when OPTIND is set.
This is used to implement the POSIX behavior when OPTIND=1
- Call setvarsafe instead of setvar. If one ran
	"getopts optstr badvariable"
  where badvariable contained an illegal variable name, there was no way
  to recover, since setvar() would longjmp on the error.
1996-06-25 16:47:43 +00:00
christos 02b3c16118 change sethistsize() to take the history size as an argument so it can
be used directly by the new variable callback functions.

christos 9a738ef22d const poisoning. 1996-06-25 16:40:38 +00:00
christos 70ad20e9f1 Include header files to get function prototypes; don't use home grown ones. 1996-06-25 16:40:06 +00:00
christos 0bc88b2434 getopts fixes:
1. OPTIND value was not computed correctly when the argument was part of the
   option string (i.e. for "l:" "-l 1" was working "-l1" was not). (PR/2505).
2. OPTARG was not being unset in case of errors [in the non POSIX error case].
3. optvar could be set to random values.
4. Option string starting with a : was not treated specially as POSIX
   specifies (if the option string starts with a :, then there is no
   error printed when there are missing option arguments or illegal options,
   and OPTARG and optvar are being set specially).
5. Implemented getopts "opts" optvar [arg]. The optional argument case
   was not implemented.

To do:
- what does Posix say about resetting the getopts state? Bash does it
  by setting OPTIND=0; is that correct? Should we be doing the same thing?
- should we be using getopt(3) for everything internal to the shell? Is that
  feasible because we might need to handle multiple invocations at once.

cgd ad8b41fa2a don't spew an error message if setlocale(LC_ALL, ""); fails. This is for
consistency with other programs, and because currently it can never
actually succeeed if LANG is set to something other than "C".  Sent
in by me in PR 2486, approved by jtc).

cgd edc0ef345c Fix growstackblock() 'newlen' calculations:
(1) it needs to be ALIGNed for both halves of the 'if,' and
	(2) if you're going to claim that you now have ALIGN(newlen)
	    bytes left, you should have actually allocated
	    ALIGN(newlen), rather than just 'newlen' bytes.

cgd 6e72825941 Previous change (Use const qualifier with conversion tables) is broken.
(1) It won't compile, and (2) there's code in dd.c which actually
does modify (some, all, used?) conversion tables, so they can't _all_ be
const (if any can).
