22ea47ec90 sh: Fix compiler warnings related to duplicate or missing declarations. 2015-03-01 21:46:55 +00:00

7696168706 sh: Allow kill %job on jobs started without job control.
When killing a %job started without job control, kill all processes in it.
As with process groups and zombies, if any process in the job can be killed
or has already terminated, the command is successful.

This also fixes occasional failures of the builtins/kill1.0 test.

454a02b372 sh: Fix duplicate prototypes for builtins.
Have mkbuiltins write the prototypes for the *cmd functions to builtins.h
instead of builtins.c and include builtins.h in more .c files instead of
duplicating prototypes for *cmd functions in other headers.

0a62a9caa9 sh: Add kill builtin.
This allows specifying a %job (which is equivalent to the corresponding
process group).

Additionally, it improves reliability of kill from sh in high-load
situations and ensures "kill" finds the correct utility regardless of PATH,
as required by POSIX (unless the undocumented %builtin mechanism is used).

Side effect: fatal errors (any error other than kill(2) failure) now return
exit status 2 instead of 1. (This is consistent with other sh builtins, but
not in NetBSD.)

Code size increases about 1K on i386.

5fe9123ff5 sh: Add a function to print warnings (with command name and newline).
This is like error() but without raising an exception.
It is particularly useful as a replacement for the warnx macro in
bltin/bltin.h.

6a6760db7f sh: Make warnings in the printf builtin non-fatal, like in the program.
The #define for warnx now behaves much like the libc function (except that
it uses sh command name and output).

Also, it now uses C99 __VA_ARGS__ so there is no need for three different
macros for 0, 1 or 2 parameters.

7f39c0011f sh: Remove unused man page for echo builtin.
The information in sh(1) about the echo builtin is equivalent, though less
extensive.

The echo(1) man page (bin/echo/echo.1) is different.

Unfortunately, sh's echo builtin and /bin/echo have gone out of sync and
this probably cannot be fixed any more.

3b53d3803e Fixed warnx format errors in printf and csh, and snprintf format errors
in sh, by using separate macros for the 1, 2 and 3-arg calls to warnx.
(The 3-arg warnx macro in sh/bltin/bltin.h used to require bogus dummy
args.)

4417f6297d Fix for PR#1287. This makes sh behave sensibly in case statements in the
face of aliases.  Note, bash doesn't do aliases while running scripts, but
"real" ksh does..

Also:
  Reduce redundant .Nm macros in (unused) bltin/echo.1
  nuke error2, it's hardly used.
  More -Wall cleanups
  dont do certain history operations if NO_HISTORY defined
  handle quad_t's from resource limits

aa9caaf657 Merge of 4.4-Lite2 sh source, plus some gcc -Wall cleaning. This is a
merge of parallel duplicate work by Steve Price and myself. :-]

There are some changes to the build that are my fault...  mkinit.c was
trying (poorly) to duplicate some of the work that make(1) is designed to
do.  The Makefile hackery is my fault too, the depend list was incomplete
because of some explicit OBJS+= entries, so mkdep wasn't picking up their
source file #includes.

This closes a pile of /bin/sh PR's, but not all of them..
