CVS log for floppy-darwin/fd.h

Checking in leak-debugging code, along with a fix for a nasty bug where
we leaked semaphores like a sieve.


dgatwood@mklinux.org

Fix for the random stack corruption panic.  The panic occurred when
doAsyncReadWrite requests were handled synchronously.  Changing back
to spawning a thread made the panic go away.  Dunno.  :-)


dgatwood@mklinux.org

Fixed broken build style changes.  I didn't notice this before because
pbxbuild appears to ignore them....


dgatwood@mklinux.org

Moved REVISIONSTRING into a file that's included from the C++ files so
that this thing will actually build again.  D'oh!


dgatwood@mklinux.org

Okay, calling it 0.7.

dgatwood@mklinux.org

Updated some copyrights and stuff.

Major hack.  I've replaced the printf statements en masse in one particular
file with a delay(100) followed by the printfs.  The driver works much
better now.  Apparently, some printf statement happens to be in a spot
where a delay is needed, but is missing.  I'm not sure where.  In any
case, it works now, and that's what matters, right?  ;-)

Turned debugging back on.

Apparently, either I wrapped a bit too much code with a "#if (MACH_DEBUG)"
directive (unlikely, since I don't think I added any this round) or there
is a depressingly timing-sensitive bug in this code.  Either way, the
driver works when all the debug printfs are turned on and fails when they
aren't.  Miserably.  I'll try to debug this more soon.

Until then, enjoy the driver, and sorry for all the noise in your syslog.
In the words of God (and indeed, the final words of God to man), "We
apologize for the Inconvenience."  (Obscure HGG reference.)


dgatwood@mklinux.org

re-disabled most of the debugging output.  Apparently missed a little bit.
Will try back later.

Turns out the write support issues were a hardware problem.  While
really noisy, this code reads and writes.  Cleanup pending.


dgatwood@mklinux.org

Fixed a double free (IOFree).  Fixed a number of subtle timing bugs that
turned out to be caused by a small error in the design of WaitForOSEvent
(or more accurately, the design of the Mac OS X rewrite of the above).
Added a warning around debugging code that was royally hosing the ability
to do certain things.  (Ironically, it allowed MS-DOS disks to work, but
caused HFS disks to fail.)

Remaining bug count: 1 (read-only problem)


dgatwood@mklinux.org

Hideously messy stuff.  This was "working" before the latest changes --
it couldn't quite eject, though, because the event was occurring before
the wait.  Moved to semaphores to get preposting behaviour.  Praying.


dgatwood@mklinux.org

Added locking for hardware lock section.  Bloody MkLinux code worked on a
wing and a frigging prayer.  I'm going to fix this in the MkLinux source
when I get done with this.  :-)


dgatwood@mklinux.org

Major changes to get around lack of the bsd sleep() function.  Wrote my own.


dgatwood@mklinux.org

Updated pieces.

Initial revision

My pet project.  Working on porting MkLinux's floppy driver to Mac OS X
to support the beige G3 machines, the Wallstreet PowerBook, and any older
machines as appropriate.  This is the first import.  It builds, but does
not actually do anything yet.
