PR bin/48875 (is related, and ameliorated, but not exactly "fixed")
Import a whole set of tree evaluation enhancements from FreeBSD.
With these, before forking, the shell predicts (often) when all it will have to do after forking (in the parent) is wait for the child and then exit with the status from the child, and in such a case simply does not fork, but rather allows the child to take over the parent's role.
This turns out to handle the particular test case from PR bin/48875 in such a way that it works as hoped, rather than as it did (the delay there was caused by an extra copy of the shell hanging around waiting for the background child to complete ... and keeping the command substitution stdout open, so the "real" parent had to wait in case more output appeared).
As part of doing this, redirection processing for compound commands gets moved out of evalsubshell() and into a new evalredir(), which allows us to properly handle errors occurring while performing those redirects, and not mishandle (as in simply forget) fd's which had been moved out of the way temporarily.
evaltree() has its degree of recursion reduced by making it loop to handle the subsequent operation: that is instead of (for any binop like ';' '&&' (etc)) where it used to evaltree(node->left); evaltree(node->right); return; it now does (kind of) next = node; while ((node = next) != NULL) { next = NULL;
if (node is a binary op) { evaltree(node->left); if appropriate /* if && test for success, etc */ next = node->right; continue; } /* similar for loops, etc */ } which can be a good saving, as while the left side (now) tends to be (usually) a simple (or simpleish) command, the right side can be many commands (in a command sequence like a; b; c; d; ... the node at the top of the tree will now have "a" as its left node, and the tree for b; c; d; ... as its right node - until now everything was evaluated recursively so it made no difference, and the tree was constructed the other way).
if/while/... statements are done similarly, recurse to evaluate the condition, then if the (or one of the) body parts is to be evaluated, set next to that, and loop (previously it recursed).
There is more to do in this area (particularly in the way that case statements are processed - we can avoid recursion there as well) but that can wait for another day.
While doing all of this we keep much better track of when the shell is just going to exit once the current tree is evaluated (with a new predicate at_eof() to tell us that we have, for sure, reached the end of the input stream, that is, this shell will, for certain, not be reading more command input) and use that info to avoid unneeded forks. For that we also need another new predicate (have_traps()) to determine of there are any caught traps which might occur - if there are, we need to remain to (potentially) handle them, so these optimisations will not occur (to make the issue in PR 48875 appear again, run the same code, but with a trap set to execute some code when a signal (or EXIT) occurs - note that the trap must be set in the appropriate level of sub-shell to have this effect, any caught traps are cleared in a subshell whenever one is created).
There is still work to be done to handle traps properly, whatever weirdness they do (some of which is related to some of this.)
These changes do not need man page updates, but 48875 does - an update to sh.1 will be forthcoming once it is decided what it should say...
Once again, all the heavy lifting for this set of changes comes directly (with thanks) from the FreeBSD shell.

An initial attempt at implementing LINENO to meet the specs.
Aside from one problem (not too hard to fix if it was ever needed) this version does about as well as most other shell implementations when expanding $((LINENO)) and better for ${LINENO} as it retains the "LINENO hack" for the latter, and that is very accurate.
Unfortunately that means that ${LINENO} and $((LINENO)) do not always produce the same value when used on the same line (a defect that other shells do not share - aside from the FreeBSD sh as it is today, where only the LINENO hack exists and so (like for us before this commit) $((LINENO)) is always either 0, or at least whatever value was last set, perhaps by LINENO=${LINENO} which does actually work ... for that one line...)
This could be corrected by simply removing the LINENO hack (look for the string LINENO in parser.c) in which case ${LINENO} and $((LINENO)) would give the same (not perfectly accurate) values, as do most other shells.
POSIX requires that LINENO be set before each command, and this implementation does that fairly literally - except that we only bother before the commands which actually expand words (for, case and simple commands). Unfortunately this forgot that expansions also occur in redirects, and the other compound commands can also have redirects, so if a redirect on one of the other compound commands wants to use the value of $((LINENO)) as a part of a generated file name, then it will get an incorrect value. This is the "one problem" above. (Because the LINENO hack is still enabled, using ${LINENO} works.)
This could be fixed, but as this version of the LINENO implementation is just for reference purposes (it will be superseded within minutes by a better one) I won't bother. However should anyone else decide that this is a better choice (it is probably a smaller implementation, in terms of code & data space then the replacement, but also I would expect, slower, and definitely less accurate) this defect is something to bear in mind, and fix.
This version retains the *BSD historical practice that line numbers in functions (all functions) count from 1 from the start of the function, and elsewhere, start from 1 from where the shell started reading the input file/stream in question. In an "eval" expression the line number starts at the line of the "eval" (and then increases if the input is a multi-line string).
Note: this version is not documented (beyond as much as LINENO was before) hence this slightly longer than usual commit message.

Fixes from David Laight: - ansification - format of output of jobs command (etc) - job identiers %+, %- etc - $? and $(...) - correct quoting of output of set, export -p and readonly -p - differentiation between nornal and 'posix special' builtins - correct behaviour (posix) for errors on builtins and special builtins - builtin printf and kill - set -o debug (if compiled with DEBUG) - cd src obj (as ksh - too useful to do without) - unset -e name, remove non-readonly variable from export list. (so I could unset -e PS1 before running the test shell...)

An initial attempt at implementing LINENO to meet the specs.
Aside from one problem (not too hard to fix if it was ever needed) this version does about as well as most other shell implementations when expanding $((LINENO)) and better for ${LINENO} as it retains the "LINENO hack" for the latter, and that is very accurate.
Unfortunately that means that ${LINENO} and $((LINENO)) do not always produce the same value when used on the same line (a defect that other shells do not share - aside from the FreeBSD sh as it is today, where only the LINENO hack exists and so (like for us before this commit) $((LINENO)) is always either 0, or at least whatever value was last set, perhaps by LINENO=${LINENO} which does actually work ... for that one line...)
This could be corrected by simply removing the LINENO hack (look for the string LINENO in parser.c) in which case ${LINENO} and $((LINENO)) would give the same (not perfectly accurate) values, as do most other shells.
POSIX requires that LINENO be set before each command, and this implementation does that fairly literally - except that we only bother before the commands which actually expand words (for, case and simple commands). Unfortunately this forgot that expansions also occur in redirects, and the other compound commands can also have redirects, so if a redirect on one of the other compound commands wants to use the value of $((LINENO)) as a part of a generated file name, then it will get an incorrect value. This is the "one problem" above. (Because the LINENO hack is still enabled, using ${LINENO} works.)
This could be fixed, but as this version of the LINENO implementation is just for reference purposes (it will be superseded within minutes by a better one) I won't bother. However should anyone else decide that this is a better choice (it is probably a smaller implementation, in terms of code & data space then the replacement, but also I would expect, slower, and definitely less accurate) this defect is something to bear in mind, and fix.
This version retains the *BSD historical practice that line numbers in functions (all functions) count from 1 from the start of the function, and elsewhere, start from 1 from where the shell started reading the input file/stream in question. In an "eval" expression the line number starts at the line of the "eval" (and then increases if the input is a multi-line string).
Note: this version is not documented (beyond as much as LINENO was before) hence this slightly longer than usual commit message.

Deal with \newline line continuations more correctly. They can occur anywhere (*anywhere*) not only where it happens to be convenient to the parser...
This fix from FreeBSD (thanks again folks).
To make this work, pushstring()'s signature needed to change to allow a const char * as its string arg, which meant sprinkling some const other places for a brighter appearance (and handling fallout).
All this because I wanted to see what number would come from
echo $\ {\ L\ I\ N\ E\ N\ O\ }
and was surprised at the result! That works now...
The bug would also affect stuff like
true &\ & false
and all kinds of other uses where the \newline occurred in the "wrong" place.
An ATF test for sh syntax is coming... (sometime.)

Fixes from David Laight: - ansification - format of output of jobs command (etc) - job identiers %+, %- etc - $? and $(...) - correct quoting of output of set, export -p and readonly -p - differentiation between nornal and 'posix special' builtins - correct behaviour (posix) for errors on builtins and special builtins - builtin printf and kill - set -o debug (if compiled with DEBUG) - cd src obj (as ksh - too useful to do without) - unset -e name, remove non-readonly variable from export list. (so I could unset -e PS1 before running the test shell...)

VFork()ing shell: From elric@netbsd.org: Plus my changes: - walking process group fix in foregrounding a job. - reset of process group in parent shell if interrupted before the wait. - move INTON lower in the dowait so that the job structure is consistent. - error check all setpgid(), tcsetpgrp() calls. - eliminate unneeded strpgid() call. - check that we don't belong in the process group before we try to set it.

Doing the vfork work on ash on a branch to try to shake out the problems before I expose everyone to them. This checkin represents a merge of the prior work, which I backed out a while ago, to the HEAD only and does not incorporate any additional bugfixes. The additional bugfixes and code-cleanup will occur in later checkins.
For reference the patches that were used are: cvs diff -kk -r1.51 -r1.55 eval.c | patch cvs diff -kk -r1.27 -r1.28 exec.c | patch cvs diff -kk -r1.15 -r1.16 exec.h | patch cvs diff -kk -r1.32 -r1.33 input.c | patch cvs diff -kk -r1.10 -r1.11 input.h | patch cvs diff -kk -r1.32 -r1.35 jobs.c | patch cvs diff -kk -r1.9 -r1.11 jobs.h | patch cvs diff -kk -r1.36 -r1.37 main.c | patch cvs diff -kk -r1.20 -r1.21 redir.c | patch cvs diff -kk -r1.10 -r1.11 redir.h | patch cvs diff -kk -r1.10 -r1.12 shell.h | patch cvs diff -kk -r1.22 -r1.23 trap.c | patch cvs diff -kk -r1.12 -r1.13 trap.h | patch cvs diff -kk -r1.23 -r1.24 var.c | patch cvs diff -kk -r1.16 -r1.17 var.h | patch
All other changes were simply the resolution of the resulting conflicts, which occured only in the merge of jobs.c.
Begins to address PR: bin/5475
