Do you have something against adding this patch (I mean the core/shooting.c and include/camera.h part)? It's possible that it could be made better, but I'm not sure how.
Seems like a good idea to me.

A few comments:
I think the while (focus_busy) msleep(10) should time out eventually,  and not try to set focus in that case. A second or a few seems like it should be plenty

Rather than the ifdefs in the if statement I'd prefer something like
Code: [Select]
#ifdef PROPCASE_CONTINUOUS_AF
        if(shooting_get_prop(PROPCASE_CONTINUOUS_AF))
         return
#endif
..
You could maybe just use shooting_can_focus, shooting_set_focus will not actually try to set focus if those conditions aren't met, but the video check might be suspect (allowing focus when it wouldn't otherwise be allowed)

Finally, does this need to be a new ifdef? It seems like it should apply or be harmless for most cameras.

Thanks for the comments.

I considered that too, but seeing that it's never done in current code made me decide otherwise.

But I just thought of something. What if we added the focus_busy check (with timeout) to the beginning of lens_set_focus_pos()? That would in theory deal with set_focus crashes too (well, mostly)?

Fair point.

That seems OK to me. Should remove the need for the CONTINUOUS_AF / SERVO_AF checks in set_zoom, since lens_set_focus shouldn't be called if shooting_can_focus fails.

It would be much more helpful to have minimal reproducible cases than a bunch of romlogs with little context.

I tend to prioritize things that clearly impact real use cases. While it would be great if CHDK never crashed, the fact that spamming zoom/focus calls crashes some cameras is not unexpected.

If a pattern like this would appear, then a solution was near.
Probably it needs a year, maybe only one beer or two.
A blizzard could cat-alyze it too, depends on todo and voodoo.
Let´s look, what we can do for You.

I am far above contented how CHDK is implemented.
Far from cry & terror I try & error.
The best for the guest to rest, the rest for us to test a quest.

SX210, 230 & Ixus255 at last already got rid of distortion in Your testbuilds fast.
Some commmon Romlogs became repeatable or switchable, maybe featureable on each cam?
Seems successful somehow, with or without romlogs...
Could be continued right now or after first snow...

Next try of the focus_busy patch (debug version), with the focus_busy check moved to shooting_set_focus().

 It draws two numbers permanently on screen. First one would increase when setting focus failed due to a focus_busy timeout, second one would increase when focus was busy but did not time out. I've yet to find a camera where any of those numbers change from zero. Does anyone want test builds with this change?

Maybe yellow is the wrong color?  :P

How about sx50hs-100c testbuild?

{Finally found charger missing since #5163
...& romlogs, similar untouched sx230:
ASSERT!! FocusLensController.c Line 708
Same headline, but several different stories available...}

Is there a check (zoom_busy or focus_busy) in get_shooting() ?

PS: a list of some other distorted cams ):(( Ixus 120,125,130,230,240,310,870+980, S90,95, SX 200
      Some Zoom lever issues: SX 200,220,240,260,610
