KO Myung-Hun 01648d4495 scriptexec: cosmetic 2015-06-11 22:44:00 +09:00
KO Myung-Hun df2cf83f8b scriptexec: preserve original shell/interpreter path 
For example,

When failing to execute the script which starts with the above line,
an error message does not contain information for /path/to/name.
Instead, it contains only name. In addition, if /path/to/dir/, an error
message contains empty string for a name of a failed script.
 2015-06-11 22:16:17 +09:00
KO Myung-Hun b27e10a32e scriptexec: try to use shell/interpreter name as well on OS/2 
If specified path does not exist, try to use shell/interpreter name
without directory.

On OS/2, directory structures of distribution is quite different. And
Some scripts have hard coded shell/interpreter. To overcome this, allow
to use shell/interpreter name if specified path does not exist.

KO Myung-Hun 89324074c4 Prepend /@unixroot to rooted paths on OS/2

$UNIXROOT at runtime.

KO Myung-Hun 759b6ec59f Consider OS/2-style path

KO Myung-Hun 9b30ce1a6d Support extproc on OS/2

KO Myung-Hun 5127457319 Read in text mode, write in binary mode on OS/2 
This enables to convert CR+LF to LF when reading, but disables to
convert LF to CR+LF when writing.

Instead, however, CR+LF are not passed into mksh as is.

KO Myung-Hun a3fdbc6802 Make all the files executable on OS/2 
On OS/2, an executable status is determined by an extension such as .exe
not real executable mode.

Script files without executable extensions such as .exe, cannot be
executed.

tg e1cda74d04 SECURITY: fix integer overflows related to file descriptor parsing 
bug initially found by Pawel Wylecial (LP#1440685)
additional bug found and suggested fix by enh (elliott hughes)

This commit also renames struct ioword.flag to ioflag to disambiguate
it from other members named “flag”, changes it to an unsigned type,
and packs ioflag and unit into shorts each, to make the struct smaller
(aligned even: 16 bytes on 32-bit systems) and reviews some of the
code involved in fd handling, though there wasn’t much to be found.

tg 1248a0a521 basically unbreak use of $*/$@ in here documents 
a bit funny:
with NUL IFS, $* behaves like dash ('ab') and $@ like bash/ksh93 ('a b')

with WS or NWS IFS, all shells behave alike though
