running it on “~/.” (must be a directory) in a global readonly variable
• if readlink fails, use some more or less sane values (no idea what csh(1)
does in these cases, maybe some feedback here?)
• optimise, while here
• dirs, pushd, popd like ports/shells/csh (Berkeley C shell)
• precmd, chpwd like ports/shells/zsh (Z shell)
and implement keeping ${DIRSTACK[0]} up to date via chpwd()
instead of doing it on entry of pushd and dirs (so that it
can be used directly)
this is slow compared to earlier, but people seem to want it
i.e. uint32_t and uint64_t
• faking <stdint.h>: u_int32_t is not part of ISO C99, so
do not add it there
• add a test if u_int32_t is declared, for the sake of the
fucked up OpenBSD standard arc4random(3) declaration, and
define it to uint32_t if the former type is not available,
e.g. on Solaris or if we fake <stdint.h>
• fix detection of arc4random_pushb(3) and the prototypes
if one of the things above applied to our system
• fix detection of arc4random function suite prototypes if
they are added via an arc4random.c file in the srcdir, and
copy that file into builddir (if it does not already exist)
to keep these isolated from each other
based on a real-life bug report by cnuke@ at the Croatian restaurant ☺☻
unbreaks “set ±o arc4random” on Solaris, both SUNpro and GCC
from netbsd via oksh
we had the NULL pointer deref already fixed
• avoid a bogus not-setting the return value of edit.c:x_file_glob()
introduced by the above change in oksh
• escape ? as well (but not ] because that’s wrong)
reminded by cbiere@netbsd via oksh
• Unsetting a non-existent variable is not an error. See
http://www.opengroup.org/onlinepubs/009695399/utilities/unset.html
report from Arkadiusz Miskiewicz; fixed based on
http://cvs.pld-linux.org diff via oksh but modified slightly
• Be more smart waiting for input for non-interactive scripts. Fix
based on a diff from debian: see their bug#296446 (via oksh)
modified slightly
this also fixes cnuke@’s “mksh busy loop” problem, for which I never
received a bug report, but the Debian bug page contains a set of two
scripts to reproduce this before (and no longer after) this commit
• some KNF
• bump version
In contrast to AT&T ksh93, its semantics are like GNU bash in that it ap-
pends the current working directory to the search path; it is implemented
as a shell alias instead of enhancing funcs.c:shbuiltins[] like in ksh93.
so that archite@midnightbsd won’t have to add evil kludges to oksh again if
they switch their ksh to mksh ☺
both “clear-screen” and “error” aren’t bound; default binding for ^L stays,
as usual, “redraw” (principle of least surprise); however GNU bash converts
also might want to put “bind ^L=clear-screen” into their ~/.mkshrc.
