dosemu-1.1.3.3 for testing

[Bart Oldeman]

Hi,

a new prerelease is available at http://www.dosemu.org/testing
This includes the keyboard fixes, the 30 minutes in DOS EDIT problem, the
hlist fix (255 times "dir" gave problems), various other MFS (for
lredir'ed drives) changes, some DPMI PIC fixes and some of part of the
work to get non-suid-root IPX working.

I also included Per's get PID and PPID patch and Clarence's patch to show
the current program in the xdos title bar if you run comcom.com.

See the Changelog (in the patch) for other things and more details.

It would be good to get some feedback from people who need locking (for
Clipper, FoxPro and friends) as I changed the file locking scheme to be
more like what DOS expects and also added a patch from Sergey.

Especially if it is worse than before please tell me.

If you still have problems with locking try the patch from Sergey and see
if it makes a difference. It should not go in until we understand the bit
fiddling however.

  Locking works in 1.1.3.4 under MS-DOS 6.22 and DR-DOS 7.03.
  And not works under FreeDOS with updated kernel to 1.1.26b
  (Build 2026b) and FreeCom to 0.83 Beta 44 [Jul 29 2002 22:42:06].
  I use FoxPro 2.6 for DOS.

Yes indeed, 1.1.3.4 is out now too. There was a nasty buffer overflow in
the MFS code that needed to be fixed. At the same time there were still
a lot of small patches from Stas. Sound should be next.

I know - the FreeDOS kernel loses its ("open") locking bits somewhere on
their way to the MFS. This should be fixed in kernel 2027.
There is a 2027test kernel at
http://freedos.sourceforge.net/kernel
even there is still a problem with "extended open" - int21/ah=6c. Well,
stay tuned: the final 2027 should be out later this month.

Thanks for testing
Bart

Neither 1.1.3.3 nor 1.1.3.4 don't solves the locking problems with
clipper apps. The behaviour is the same as before.
