Changelog
=========
Release 2019-02-18:
- libgetopt: The undocumented variable "_sp" from SVr4 has been renamed
to "opt_sp" and (on platforms that support "#pragma weak") there
is a weak reference _sp to that new variable, giving backwards
compatibility.
The reason for doing this is to make sure that people on Illumos
or Oracle Solaris, who still have an outdated version of getopt()
in their local libc, do not try to link the Bourne Shell only
against their old getopt(). If they did this, they would not get
the documented enhanced getopt() features from the Bourne Shell.
- Bourne Shell: The shell now uses "opt_sp" as the name for the
undocumented additional getopt() interface from AT&T. This has
been done to avoid being able to link the Bourne Shell on
Illumos or Oracle Solaris without using our libgetopt. If this
was done, we could not support UNIX/MULTICS style long options
and we could not support -help/--help, since the latter is
implemented via long options that are not an alias to short
options.
- Bourne Shell: added a new timestamp to the Bourne Shell version.
Release 2018-11-21:
- Bourne Shell: make it exit the whole shell with set -e after a command
substitution failed on the right side of a variable assignment
that has no command. This is required by POSIX.
- Bourne Shell: added a unit tests for the above case.
- Bourne Shell: New version date set to 2018-12-08 the this change.
Release 2019-01-22:
- bsh / Bourne Shell / star: the function hop_dirs() no longer checks
for p2 != NULL before calling *p2 = '/' as p2 has
been granted to be != NULL from a break with
strchr(p, '/') == NULL
Thanks to Pavel Raiskup for poiting to a related
Coverity message.
- Bourne Shell: Added a missing /* FALLTHROUGH */ comment..

message.
- Bourne Shell: added a range check for $OPTIND to tge getopts(1)
implementation
Thanks to Pavel Raiskup for poiting to a related Coverity

- Bourne Shell: Removed a nonsense variable in expand() that caused
Coverity not to understand that a directory was correctly
closed()
Thanks to Pavel Raiskup for poiting to a related Coverity
message.
- Bourne Shell: Added a paranoia comparison to make Coverity quiet.
Thanks to Pavel Raiskup for poiting to a related Coverity

- Bourne Shell: avoid to call catpath() with a NULL pointer for path
Thanks to Pavel Raiskup for poiting to a related Coverity
message.
- Bourne Shell: check the write() return code in io.c
Thanks to Pavel Raiskup for poiting to a related Coverity
message.
- Bourne Shell: Added a paranopia check for "test -o" to make Coperity
quiet.
Thanks to Pavel Raiskup for poiting to a related Coverity
message.
- Bourne Shell: Added (void) before fcntl() in hope to make Coverity
quiet.
Thanks to Pavel Raiskup for poiting to a related Coverity
message.
- Bourne Shell: Removed dead code from readwc()
Thanks to Pavel Raiskup for poiting to a related Coverity
message.
- Bourne Shell: Cstyle changes to xec.c
- Bourne Shell: "builtin -d ..." did access free()d memory.
Thanks to Pavel Raiskup for poiting to a related Coverity
message.
- Bourne Shell: expand.c: added a check for fd == -1 to avoid calling
openat() with that fd.
Thanks to Pavel Raiskup for poiting to a related Coverity
message.
-Bourne Shell: func.c: added a check for fd == -1 to avoid calling
read()/close() with that fd.
Thanks to Pavel Raiskup for poiting to a related Coverity
message.
- Bourne Shell: jobs.c: enlarged a buffer to be of same size as
numbuf[] to avoid a potential buffer overflow.
Thanks to Pavel Raiskup for poiting to a related Coverity
message.
- Bourne Shell: print.c::prt_cntl() had a very old (AT&T) bug with
printing byte sequences that get an error with mbtowc() and it
did not print byte sequences correctly that refer to legal but
"nonprintable" multi byte characters.
Thanks to Pavel Raiskup for poiting to a related Coverity
message.
- Bourne Shell: xec.c: the reserved word "time" could cause to
access uninitialized memory if the string in $TIMEFORMAT
contains the format %J
Thanks to Pavel Raiskup for poiting to a related Coverity
message.
- Bourne Shell: xec.c: added a paranoia check on whether
findnam("funcname") returns NULL even though the existence of
a function with that name already has been verified via the
hash service.

message.
Release 2019-02-18:
- Bourne Shell: Another vfork() problem has been fixed. "trap cmd EXIT"
has incorrectly called "cmd" after a non-existing command was.
called by the shell. This was a result of the shared data from
vfork().
Thanks to Martijn Dekker for reporting.
- Bourne Shell: A unit test case for the above bug has been added.
- Bourne Shell: __growstak() now always uses realloc() on modern
platforms. This may speed up things up to 15%.
Thanks to Jan Engelhardt for reporting.
Release 2019-03-11:
- libgetopt/Bourne Shell: added an #ifndef __CYGWIN__ in order to avoid
overwriting non-standard definitions by standard
definitions on Cygwin for the global getopt()
variables.
Thanks to Heiko Ei[eszett]feldt for proposing this
fix.
- Bourne Shell: better comment in bltin.c
