Remove 'l'. Those who do not learn from history are doomed to repeat it.

Many users needlessly maintain the alias 'l' (or 'll') for 'ls -l'. We
should ease the burden on our users and supply a default system which is
modern and has a full complement of the features they expect (or even some
they don't -- more features don't hurt any one after all).

Suggested by perry@ in <87wt2uxhbx.fsf@snark.piermont.com> and submitted
for discussion to some NetBSD developers, who suggested that rather than
my own idiosyncratic 'll', 'l' was a much better name.

It may prove possible to merge this code with 'ls' in the future.

lint: suppress "used but not defined" for bin, sbin, usr.bin, usr.sbin

These diagnostics are emitted by lint2, and like all diagnostics from
lint2, they don't affect the exit status.

In libc, lint cannot handle the renamings from namespace.h, generating
many false positive diagnostics since 'libc_function' is used but
'_libc_function' is defined. Until this situation is handled properly,
suppress this diagnostic.

{usr.,}{s,}bin: replace LINT_SUPPORTED with the standard NOLINT

sprinkle a little const, and now everything compiles with WARNS=3

Revert previous; the change that required it will be done differently.

Only use the MKDYNAMICROOT semantics (i.e. -rpath=/lib,/usr/lib and
-dynamic-linker=/libexec/ld.elf_so) if the BINDIR of the program being
built is /bin or /sbin.

The reason we do this is because now all programs *except* those in
/bin and /sbin (i.e. the "special cases") match the default the compiler
uses, which is what is used for things in e.g. xsrc, pkgsrc, and other
random 3rd party programs.

Implement MKDYNAMICROOT, which currently defaults to "no", but will
be changed in the future to "yes".

If MKDYNAMICROOT == "no", there is no change from existing behaviour
of a static /bin and /sbin (and a few programs in elsewhere).

If MKDYNAMICROOT == "yes", the following changes occur:
in <bsd.own.mk>:
SHLIBDIR?= /lib
SHLINKDIR?= /lib
in various Makefiles, the following entry is DISABLED.
LDSTATIC?=-static
This results in all programs (except those "standalone" programs built
in sys/arch/*/stand) are linked dynamically, the shared linker is moved
from /usr/libexec to /lib (with a compat symlink), and the shared
libraries used by /bin and /sbin programs are moved from /usr/lib to
/lib (with compat symlinks).

change from WARNS?=1 to WARNS?=2 for bin/

pull bsd.own.mk in before LDSTATIC?=-static, so that LDSTATIC can be
overridden by bsd.own.mk/mk.conf.

Remove unused code left over from temporary printescaped functionality.
Noted by Jeff Ito in PR bin/23966.

Overhaul how `build.sh tools' are used:

* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h

* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.

These changes should make it easier to "tool-ify" a program by adding:
#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif
to the top of the source files (for the general case).

Fix the "dne" handling and chmod behaviour properly: values of dne
need to be on a stack instead of being a single variable since
directories are processed depth-first. Otherwise dne randomly
depends on the previously processed entry.

This fixes both chmod of non-created directories (they used to be
chmod'd even when not created if their last child element did not
exist in the target subtree) and a "foo exists" bug exposed by my
last commit which removed directory sorting.

all regression tests passed

Remove fts sorting. It was originally put there to copy files
before directories since files (usually) are in the same cylinder
group and subdirectories aren't. However, this mostly changed with
the new ffs dirpref algorithm in 2001.

No sorting has two effects:
1) copy appears to be somewhat faster (e.g. on my laptop cp'ing build
objdir to tmpfs is 7% faster after the change)
2) source file parameters no longer get randomly shuffled due to
fts doing an unstable sort of them. this means that
"cp 1 2 3 4 dest/" will copy the files in that order instead
of e.g. 3 4 1 2.

Remove the \n and tabs from the __COPYRIGHT() strings.

Distinguish "this file failed" from "any file failed", to make cp -v
output behave itself. PR bin/37018 from Dieter Roelants.

(I used a slightly different patch to make sure "any file failed"
didn't get lost in the shuffle, and renamed the variables in the name
of greater clarity.)

Disable mmap path. With the current vnode locking scheme it has
a very annoying property: if the source media is slow (like a slow
network), the target file will be locked for the duration of the
entire max 8MB write and cause processes attempting to e.g. stat()
it to "tstile" (for several minutes in the worst case). Revisit
this if/when vnode locking gets a little smarter.

Don't remove the destination file if there is a write error. This is

Rework how dependency generation is performed:

* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
This is a change of behaviour. If a Makefile wants the clean semantics
it must specifically append to CLEANFILES.
Resolves PR toolchain/5204.

* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
that have a suffix of: .c .m .s .S .C .cc .cpp .cxx

* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES

* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}

* Deprecate the (short lived) DEPENDSRCS


Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.

Tested with "make -j 8 distribution" and "make distribution".

PR/45856: Bernhard "Burnhard" Riedel: Infinite loop on &nbsp; input. Sending
char 160 in the input to csh, lead it to an infinite loop, because tcsh tables
counted this as a space character, but the word logic switch does not. Change
that character tables, so that this does not count as a spacing character
anymore, by syncing the table with the one from tcsh.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22249, verified by myself.

ANSIfication and KNF improvements by Petri Koistinen in bin/13689,
with some fixes by me.

Rename err.h to errnum.h to avoid collision with err.h
Fix compiler warnings.

convert to new RCS id conventions.

Merge 4.4-Lite version.

Add RCS identifiers.

changed "Id" to "Header" for rcsids

added rcs ids to all files

there.

csh(1): Nix trailing whitespace in man page.

No functional change intended.

Improve the description of the jobs built-in.

branches: 1.57.4;
Change back various occurrences of \*[Le], \*[Ge] (less/greater equal)
and \*(ua (upwards arrow) to literal "<=", ">=" and "^" whenever
appropriate (e.g., in code examples).

csh(1): fix punctuation at the end of an .Xr line

like zsh, have jobs -Z do setproctitle

Remove workaround for ancient HTML generation code.

C Shell appeared in 2BSD, not 3BSD

Bump date for previous.

Remove alloc builtin, it did not work anyway since most modern malloc
implementation use a combination of sbrk/mmap.

branches: 1.50.2;
Fix whitespace nits. Suggested by Bug Hunting.

branches: 1.49.4;
Fix sub-section references.

Use .In instead of .Aq .Pa for signal.h.

Bump date for previous.

- 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 :-)

Use .Rs/.Re for reference to C shell introduction.

Remove weird backslash that somehow must have crept in.
