Searching the installed man pages for SDL functions fails, e.g.
  man -k SDL_ |grep Video
After investigating this I found that "makewhatis", the tool that generates
the "whatis" database, reads the SDL_* man pages, but doesn't produce
entries in the "whatis" database for the SDL_* man pages.
After some more debugging I found the reason is a missing space.
After editing SDL_Init.3(.gz) and replacing
   SDL_Init\- Initializes SDL
with
   SDL_Init \- Initializes SDL
everything works fine.
After running "makewhatis" I can successfully do a
   man -k SDL_
and SDL_Init is listed in the output.

I recognized this problem from a few years back, when I encountered it while
working on the Xv blitter for xmame. The problem is that for some reason
creation the Xvport and XvImage succeeds, and failure (lack of resources / hw
capability?) is only indicated during the first XvPut[Shm]Image. I've written a
patch for SDL using the work around for this I developed for xmame (and which
is still used successfully in xmame after many years of usage).

I'll admit it isn't very pretty, but after investigating several possibilities
this was the best option, any other fixes would need changes to the SDL api and
abi.

Subject: [SDL] SDL Semaphore implementation broken on Windows?
Hi,

Over the past couple of days, I've been battling with SDL, SDL_Mixer and SMPEG to try to find an audio hang bug.  I believe I've found the problem, which I think is a race condition inside SDL's semaphore implementation (at least the Windows implementation).  The semaphore code uses Windows' built in semaphore functions, but it also maintains a separate count value.  This count value is updated with bare increment and decrement operations in SemPost and SemWaitTimeout - no locking primitives to protect them.

In tracking down the apparent audio bug, I found that at some point a semaphore's count value was being decremented to -1, which is clearly not a valid value for it to take.

I'm still not certain exactly what sequence of operations is occuring for this to happen, but I believe that overall it's a race condition between a thread calling SemPost (which increments the count) and the thread on the other end calling SemWait (which decrements it).

I will try to make a test case to verify this, but I'm not sure if I'll be able to   (threading errors being difficult to reproduce even in the best    circumstances).

However, assuming this is the cause of my problems, there is a very
simple fix:
Windows provides InterlockedIncrement() and InterlockedDecrement()
functions to perform increments and decrements which are guaranteed to be atomic.  So the fix is in thread/win32/SDL_syssem.c: replace occurrences of --sem->count with InterlockedDecrement(&sem->count); and replace occurrences of ++sem->count with InterlockedIncrement(&sem->count);

This is using SDL v1.2.12, built with VC++ 2008 Express, running on a
Core 2 duo processor.

If an app requests a 24-bit opengl mode on a machine with a 32-bit desktop with
the windib video backend, then when exiting fullscreen the desktop resolution
is not restored

The reason this is, is because the windib backend restores the desktop
resolution when exiting fullscreen in DIB_SetVideoMode when it finds that the
last request was for fullscreen by checking the original flags on the video
surface. However, if the bits per pixel requested is different than current
surface, the video surface is recreated and the original video flags are lost.
So the check to see if we were exiting fullscreen fails.

below is a patch to SDL_dibvideo.c that solves the problem by using the
original flags in all cases.

thanks!

Subject: [SDL] SDL_INPUT_LINUXEV vs SDL_JOYSTICK_LINUXEVHello all,

There seems to be a slight inconsistency between the SDL_INPUT_LINUXEV
define (used in src/joystick/linux/), and SDL_JOYSTICK_LINUXEV defined
in include/SDL_config.h.

SDL_JOYSTICK_LINUXEV is never used, and SDL_INPUT_LINUXEV is not
mentioned in SDL_config.h.in (though set by the ./configure script).
This has the unfortunate effect of breaking the joystick detection on linux
boxes where /dev/input/event* is defined, but not /dev/(input/)?js*.

Trivial patch included.

Cheers.

Fix for some Cocoa memory management problems.

OK, I think I've nailed the memory management problems with the attached patch.
Too late for the release, but oh well. It shows that I haven't done much Cocoa
lately... took me a while to figure out that NSWindows don't retain their
delegate.

I'm working on that now, thanks for reporting it.  What I'm doing is if the
width and height are the same, I'm leaving the window position alone, but if
they're different they will respect the positioning environment variables.

We do grab the system colors if the application requested fullscreen or a

This allows gamma fading, etc. to work, and is what previous versions did.

Don't crash if passed a NULL overlay.  The app crashes anyway, since
it's not checking the return value of the create call, but at least it's
not crashing in SDL anymore. :)

Created an attachment (id=229) [details]
patch to reinstate the SDL cursor after an NSApplicationActivatedEvent

Oops, you're right. My testcursor.c has diverged so far from the original that
I missed that. In fact, now that I think about it, that issue isn't even
addressed by the cursor rectangle patch - it is only concerned with windowed
mode (and fixes the problem there as a side effect). The problem in fullscreen
is still the same as before. How about the attachment for a fix? (I can confirm
that [NSCursor set] doesn't seem to have any effect when called from
QZ_DoActivate().)
