Don't know if this may be related to the leak, but worth heeding anyway 
- apparently WebKit has some serious issues, including an uncommonly 
nasty vulnerability:



   Apple releases emergency update for iPhones, iPads, and Apple Watch
   ...
   The vulnerability, discovered by Google's Threat Analysis Group,
   affects Apple's WebKit browser engine, and what makes this an
   urgent update is the fact that Apple claims the vulnerability
   is being actively exploited.

Re: [bug] strange memory leak in LC

[Andre Garzia via use-livecode]

Hi Panos,

The stack that was opened is a project that has many mainstacks in it’s 
stackfiles. Some of those stacks make use of the browser widget but the stacks 
that were open during the problem were not using it. I don’t recall the 
dictionary being open at that time either. I simply killed LC and kept going 
on, I wish I took some more time to try to investigate it but the IDE was not 
responding.

I don’t use Safari so I can really tell anything about it leaking.

Best
A

Re: [bug] strange memory leak in LC

[panagiotis merakos via use-livecode]

Hello all,

After a brief Google search it seems there are some other apps that have a
similar memory leak after upgrading to Big Sur:

https://discussions.apple.com/thread/252276774
https://discussions.apple.com/thread/252090206

The issue folks here (in this list) have mentioned does not seem to be
specific to M1 macs. It seems specific to Big Sur, since Andrew mentioned
he saw that in an iMac, and there are no M1 iMacs so far.

In the previous links people mention memory leaks in Safari. Do you also
see a memory leak with Safari? Also, did you use a stack with a browser
widget, when you experienced this issue? These 2 might be related.

Also, did you use (or did you leave open) the Dictionary stack? The
Dictionary does use a browser widget.

So far we are not able to reproduce the issue, because we either run Big
Sur on Parallels, and the VM is suspended when you choose "Sleep", or we
connect to a remote M1 Mac mini via VNC, and the connection will be lost if
we choose "Sleep" for this Mac.

Kind regards,
Panos

Big Sur 11.0.1, LC 9.6rc3

LiveCode seems to become unresponsive when my iMac goes to sleep and then wakes 
up and logs in. Don’t have any recipe for it, but when I when I left it 
overnight it had completely taken over my machine this morning.

I have 40GB of physical RAM, but LC was trying to use almost 300GB (virtual?)

Re: [bug] strange memory leak in LC

[Phil Davis via use-livecode]

I created a little "leak test" stack that runs the "leaks" shell command
against the processID of the LC engine that runs the stack. It checks
for new leaks every 60 seconds and lists the number and size of each new
leak found. I'm running it in LC 9.6.1 on 3 Macs right now - Catalina,
High Sierra and Big Sur.

After about 30 minutes:
- LC on Big Sur (M1) has 10 leaks for a total of 688 bytes.
- LC on Catalina (Intel) has no leaks.
- LC on High Sierra (Intel) has no leaks.

Just FYI -
Phil Davis

 I wonder if this is more an issue with Rosetta2 in this instance. Maybe
 something in LC leaks because of the Rosetta transformation of the binary.
 Perhaps, as a test, open the same stack on a non-AppleSilicon Mac and watch
 them both for how much memory they expend over a period of time.

 All the best with that.

Re: [bug] strange memory leak in LC

[Andre Garzia via use-livecode]

Sean,

The stack was not running anything. It was simply opened. I don’t believe it 
would leak like that. Anyway, I’m monitoring to see if it happens again.

Re: [bug] strange memory leak in LC

[Sean Cole (Pi) via use-livecode]

Wow, Andre, that's impressive. That amounts to about 34MB per minute over
48hrs. I've had a pretty massive stack (226MB file at the moment) on my Mac
sitting here over the last week. Looking in the activity monitor, LC has
987MB associated with it. and watching it over a period of time it remains
stable and even went down a tiny bit.

I wonder if this is more an issue with Rosetta2 in this instance. Maybe
something in LC leaks because of the Rosetta transformation of the binary.
Perhaps, as a test, open the same stack on a non-AppleSilicon Mac and watch
them both for how much memory they expend over a period of time.

All the best with that.

Sean

[bug] strange memory leak in LC

[Andre Garzia via use-livecode]

I have no idea what happened. I’m running LC 9.6.2-rc-3 on macOS Big Sur on M1 
ISA (so it is running under Rosetta 2). I kept the IDE opened for a couple 
days, I was working on a gaziliion stacks at the same time and was not yet 
ready to close them.

The stacks were not doing anything, they were not running “send in time” 
commands or doing any kind of processing, they were just opened. Then macOS 
showed me a dialog I have never ever seen on macOS 10.x, a memory exhaustion 
dialog. Looking closer at it, LiveCode was using 100 GB of memory, as in 
Gigabyte, as can be seen on this screenshot:

I remember things like the “default button” causing leaks due to the animation 
and so on, but all I had was a bunch of custom stacks open and the script 
editor focused. Thats it. It was open since yesterday.
