wiz 2afd9d4a18 Bump date for cd -P support. 2010-01-01 21:46:31 +00:00
dholland a5ced5a04b fix another typo 2010-01-01 19:51:19 +00:00
dholland cd0a6973f8 Make the cd builtin accept and ignore -P, which is a kshism that has been 
allowed to leak into POSIX and selects the behavior cd already implements.
Closes PR bin/42557 and also relevant to PR pkg/42168.

I suppose this should probably be pulled up to both -4 and -5...

gson dddcd98c78 Removed return statement in parser action that caused a memory leak with 
the new yacc, making "sh MAKEDEV -MM init" consume 27 MB of virtual memory
with the result that NetBSD could no longer be installed on a 32 MB system.

christos 40ab82d3c3 fix regression exit1: Don't exec the last command in a subshell if it has 
trap[0] (trap EXIT) set. Fork instead to give the shell a chance to execute
the trap when it is done.

apb db8f79df3d Make this slightly more portable; it has to run on arbitary host 
platforms at build time.  Previousy, some shells were confused by
some of the "[ ... ]" tests.

wiz 7d6100a52d Bump date for previous. 2009-03-29 08:54:10 +00:00
mrg fcc023545e - add new RLIMIT_AS (aka RLIMIT_VMEM) resource that limits the total 
address space available to processes.  this limit exists in most other
modern unix variants, and like most of them, our defaults are unlimited.
remove the old mmap / rlimit.datasize hack.

- adds the VMCMD_STACK flag to all the stack-creation vmcmd callers.
it is currently unused, but was added a few years ago.

- add a pair of new process size values to kinfo_proc2{}. one is the
total size of the process memory map, and the other is the total size
adjusted for unused stack space (since most processes have a lot of
this...)

- patch sh, and csh to notice RLIMIT_AS.  (in some cases, the alias
RLIMIT_VMEM was already present and used if availble.)

- patch ps, top and systat to notice the new k_vm_vsize member of
kinfo_proc2{}.

- update irix, svr4, svr4_32, linux and osf1 emulations to support
this information.  (freebsd could be done, but that it's best left
as part of the full-update of compat/freebsd.)


this addresses PR 7897.  it also gives correct memory usage values,
which have never been entirely correct (since mmap), and have been
very incorrect since jemalloc() was enabled.

tested on i386 and sparc64, build tested on several other platforms.

thanks to many folks for feedback and testing but most espcially
chuq and yamt for critical suggestions that lead to this patch not
having a special ugliness i wasn't happy with anyway :-)

roy 9fa1d120a0 el_gets now sets el_len to -1 on error so we can distinguish 
between a NULL string and an error.
This fixes sh from exiting with libedit now allowing EINTR to return.
We may need to expand this to an errno check in the future.

apb 125b7c8cbb In shell scripts run during the build, add a SED variable, defaulting 
to "sed".  SED=${TOOL_SED:Q} should be passed in the environment to
override this.

apb 9577284633 Don't try to remove trailing newlines from shell variables via 
constructs like ${var%$nl}.  Apparently this allows the Ubuntu Linux

Patch from PR 39786 by Andy Shevchenko.

dholland 7fb5a8c68e The field width passed for a %.*s printf format is supposed to be int, not 
ptrdiff_t; on 64-bit platforms the latter will be too wide.
Adjust accordingly.

dholland 72c2627f1f Wrap declaration of a STATIC function that's only conditionally defined

dholland 744c8edc4b Wrap declaration of a STATIC function that's only conditionally defined 
in a suitable ifdef, so things still compile if STATIC is defined as
"static", which is for some reason not the default.

(In the long run STATIC should go away - it might have once been a
portability hack but now definitely serves no purpose.)
