Renumber copyright clause 4 Renumber cluase 4 to 3, per what everybody else did when BSD granted them permission to remove clause 3. My insistance on keeping the same numbering for legal reasons is too pedantic, so give up on that point.

sh: Perform pathname generation during the first expansion phases. This avoids the need to add and remove CTLESC bytes if pathname generation will not be performed (set -f). Side effect: the order of operations is slightly different: pathname generation in ${$+* $(CMD)} will not see filesystem changes from CMD.

sh: Make struct arglist an array instead of a linked list. This simplifies the code (e.g. allowing use of qsort(3) instead of a hand-rolled mergesort) and should have better cache properties. The waste of unused args arrays after resizes is approximately the same as the savings from getting rid of the next pointers. At the same time, remove a piece of global state and move some duplicated code into a function.

sh: Expand here documents in the current process. Expand here documents at the same point other redirections are expanded but use a non-fork subshell environment (like simple command substitutions) for compatibility. Substitition errors result in an empty here document like before. As a result, a fork is avoided for short (<4K) expanded here documents. Unexpanded here documents (with quoted end marker after <<) are not affected by this change. They already only forked when >4K. Side effects: * Order of expansion is slightly different. * Slow expansions are not executed in parallel with the redirected command. * A non-fork subshell environment is subtly different from a forked process.

sh: Save/restore changed variables in optimized command substitution. In optimized command substitution, save and restore any variables changed by expansions (${var=value} and $((var=assigned))), instead of trying to determine if an expansion may cause such changes. If $! is referenced in optimized command substitution, do not cause jobs to be remembered longer. This fixes $(jobs $!) again, simplifies the man page and shortens the code.

sh: Don't do optimized command substitution if expansions have side effects. Before considering to execute a command substitution in the same process, check if any of the expansions may have a side effect; if so, execute it in a new process just like happens if it is not a single simple command. Although the check happens at run time, it is a static check that does not depend on current state. It is triggered by: - expanding $! (which may cause the job to be remembered) - ${var=value} default value assignment - assignment operators in arithmetic - parameter substitutions in arithmetic except ${#param}, $$, $# and $? - command substitutions in arithmetic This means that $((v+1)) does not prevent optimized command substitution, whereas $(($v+1)) does, because $v might expand to something containing assignment operators. Scripts should not depend on these exact details for correctness. It is also imaginable to have the shell fork if and when a side effect is encountered or to create a new temporary namespace for variables. Due to the $! change, the construct $(jobs $!) no longer works. The value of $! should be stored in a variable outside command substitution first.

sh: Do IFS splitting on word in ${v+word} and ${v-word}. The code is inspired by NetBSD sh somewhat, but different because we preserve the old Almquist/Bourne/Korn ability to have an unquoted part in a quoted ${v+word}. For example, "${v-"*"}" expands to $v as a single field if v is set, but generates filenames otherwise. Note that this is the only place where we split text literally from the script (the similar ${v=word} assigns to v and then expands $v). The parser must now add additional markers to allow the expansion code to know whether arbitrary characters in substitutions are quoted. Example: for i in ${$+a b c}; do echo $i; done Exp-run done by: pav (with some other sh(1) changes)

Create the altix project branch. The altix project will add support for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting is a two-module system, consisting of a base compute module and a CPU expansion module. SGI's NUMAFlex architecture can be an excellent platform to test CPU affinity and NUMA-aware features in FreeBSD.

Be more consistent with handling of quote mark control character. Don't output double-quotes inside variable expansion/arithmetic expansion region in here-documents. When leaving the arithmetic expansion syntax mode, adjust the dblquote flag according to previous syntax, in order to avoid splitting of quoted variables.

Better handling of word splitting. Don't record the same region multiple times when performing nested variable expansion, and preserve some quoting information in order to avoid removing apparently empty expansion result.

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.. Submitted by: Steve Price <steve@bonsai.hiwaay.net>, peter
