Please try running it directly, with NSZombieEnabled=1.

[lmjabreu]

I'm also having this problem, VERY frequent crashes,

I should add NSZombieEnabled to the growl prefpane plist right?

Nope. It's an environment variable. You'd do something like this in
the Terminal (/Applications/Utilities/Terminal.app):

NSZombieEnabled=1 /Library/PreferencePanes/Growl.prefPane/\
Contents/Resources/GrowlHelperApp.app/Contents/MacOS/GrowlHelperApp

Then you watch the Console (/Applications/Utilities/Console.app) for
output from GrowlHelperApp. When it goes to touch a dead object, the
object records lines in the Console, which you copy and send to us.

[Evan Schoenberg]

You need to quit GrowlHelperApp via Activity Monitor before executing
the above command.

If you don't quit GHA first, your request to run it won't do anything
useful.
If you quit GHA via the System Preferences pain [sic] ("stop growl"),
you'll tell Growl not to run at all, and your request to run it won't
do anything useful.

Thanks you all.

Fortunately it crashed for the 20th time today in no time.

You're pasting Console output. If you followed the steps Peter
specified to run GrowlHelperApp from the Terminal with
NSZombieEnabled, you will have output in that Terminal window. That's
the important part for this issue, as all the crashes submitted are
while releasing memory.

Actually, what would be more relevant is a crash log, since we don't
know that you're having the same crashes that dkocher is.

If it is, *then* you should run with NSZombieEnabled.

Could you please:
1) Paste the actual output, from when you entered the command in the
Terminal until GrowlHelperApp quit?
2) Not top-post? It makes an already hard-to-follow thread even
harder. Your replies to emails should go underneath the quoted text to
which you are replying.

His posted crash logs all show:

which is indeed the same crash as dkocher's by binary offsets

1 com.Growl.GrowlHelperApp 0x000228ac 0x1000 + 137388

Both traces are consistent with an over-released object crashing as it
hits its NSAutorelease pool being released.

Interesting. That's nowhere near where atos says 0x000228ac is. I'm
beginning to think that my build with debug symbols doesn't have the
same addresses as the release build…

Is there a reason we aren't simply sending ourselves an event every 30
seconds or so? That seems much less fragile than forcibly draining
(or, worse, releasing) Cocoa's autorelease pool out from under it.

Interesting, indeed. I got the address using otx on the buld
downloaded from the site directly.

We're not actually calling drain; we're just releasing. Same
difference, though. It does seem like a mistake to change autorelease
pools in the middle of a run loop, which is what we end up doing with
a normal NSTimer.

I think the correct solution is to use a run loop observer. The
attached patch does this; if it looks okay to you, I'll commit it.

Well, for one thing, watching for kCFRunLoopExit is going to get us
only called at the end of the program, if that. kCFRunLoopAfterWaiting
would be better.

But this still doesn't resolve my original objection: Draining or
releasing Cocoa's autorelease pool. Even after this patch,
GrowlApplication would still do that; it would just do it differently.

What we should do is post an event periodically, in order to provoke
Cocoa to drain/release its own pool. I thought we were already doing
this, but apparently not.

Not true. The run loop is considered exited when all sources are
handled. Our callback is called at the end of every run loop which
does anything, and is not called continuously in the absence of
anything needing handling (so it doesn't idly release and recreate the
pool continuously).

I did, of course, test this before sending it to the list.

We're not messing with Cocoa's own autorelease pool; we set up a new
one within the run method.
Differently in that it's done at a safe time instead of a potentially
dangerous one.

*shrug* As long as Growl doesn't retain memory as it used to, I have
no desire to argue over the implementation. Sending a periodic event
means that we will (1) not idle at no-activity, because we'll wake up
to send an event every X seconds and (2) still have the bizarre effect
of building up autoreleased objects for a period of time before our
pool gets emptied.

The CFRunLoopObserver documentation says:

kCFRunLoopExit
The exit of the run loop, after exiting the event processing loop.
This activity occurs once for each call to CFRunLoopRun and
CFRunLoopRunInMode.

If -[NSApplication run] is calling CFRunLoopRun repeatedly, I would
call that a bug in NSApplication; it probably should use one of the
CFRunLoop* classes for whatever it's doing.

Around Cocoa's -run method. If processing an event resets the
autorelease pool, that suggests that Cocoa creates its pool during -
run, which puts its autorelease pool inside our autorelease pool—
which means that when we release ours, we also drain/release Cocoa's.

It doesn't seem any safer.

Doing anything on a timer has those results.

I suggest combining the two solutions: When our observer is called for
kCFRunLoopAfterWaiting (or kCFRunLoopExit, if that really is more
appropriate), post an NSEvent.

My guess is that it calls CFRunLoopRunInMode() with a 'seconds' parameter of 0:

seconds

The length of time to run the run loop. If 0, only one pass is made through the run loop before returning; if multiple sources or timers are ready to fire immediately, only one (possibly two if one is a version 0 source) will be fired, regardless of the value of returnAfterSourceHandled.

That does seem reasonable.

We're releasing the pool when everything is done instead of when an arbitrary timeout is called at some point during the run loop... I had assumed that all available sources were handled in the same run loop, but the documentation for CFRunLoopRunInMode() does say that if 0 is passed for seconds, only one source would be handled.. given that, perhaps it's the same level of safety.  The timing definitely seems safer to me, though...

...safer isn't the same as safe.

(2) still have the bizarre effect of building up autoreleased

True.  The event solution is no worse in this regard than our previous implementation.  My point was that using a run loop observer eliminated the timer aspect entirely.

I suggest combining the two solutions: When our observer is called for  
kCFRunLoopAfterWaiting (or kCFRunLoopExit, if that really is more  
appropriate), post an NSEvent.

Thinking about this, it seems quite wasteful to create and produce an extra NSEvent for every iteration of the run loop.  Furthermore, wouldn't this produce an infinite loop?

I'd say we're better off with the existing timer posting an NSEvent rather than draining the pool.

Premature optimization. If we have to spend a few bytes per (30
seconds|run loop) to safely keep memory from exploding, I'm fine with
that.

> Furthermore, wouldn't this produce an infinite loop?

Hm. I'm not sure. Worth a test app.

If it does, I'd guess that it's because of the aforementioned Cocoa bug.

Could be.
