Re: Pharo 6.0 and 6.1 64 bit freeze on MacMini

Aha! similar here! Didn't do that before: resizing after freezing. So almost sure it has to do with resizing only?
1: after maximizing to full screen parts are not redrawn but still can drag windows around:

2: then after coming back and reentering full screen the everthing is redrawn again,(can't
remembering opening a Test Window probably clicked on a non refreshed part in window)
But when dragging windows parts are not redrawn (you can see almost exactly where I dragged
because the gradient background reveals differences if you'd look closely.
Still, Pharo is still alive. but doesn't redraw the parts when e.g. evaluating
something in a Playground as can be seen in the last 3rd screen dump.

So, in summary: resizing the screen in any way can freeze/unfreeze Pharo again and
screen redrawing is in error.

Please try starting your Pharo image with a new squeak vm. I remember Tobias posting something on a full screen bug fix about a year ago, and don't know what happened with it. It was around the same time as his hiDPI fix, which triggered some garbage collection issue at the time. Some part of that was then reverted.

anything that is in the squeak vm is also in the pharo vm now (since we merged).
so this recommendation is obsolete (thanks to the gods :P).

Re: Pharo 6.0 and 6.1 64 bit freeze on MacMini

ok, thanks, is there a difference in the 32 and 64 bit vm behaviour? it seemed to me they both had this error,

but I am a byte confused now.

Anyway, for the time being it is not a problem to continue with Pharo 5.0.

Re: Pharo 6.0 and 6.1 64 bit freeze on MacMini

In reply to this post by TedVanGaalen

Yesterday 23 Aug, I completely deleted all Pharo 6.1 64 bit and then downloaded and reinstalled it, but the same problems are still present.

Then I installed Squeak5.1-16549-64bit, which works without problems.
(I don't know if it uses the same VM as Pharo 6.1 64 bit?, if that is true,
then the problem could be within the image, not the VM?)

However, I do prefer using Pharo.
As written before, I'll use Pharo 5.0 until 6.x
runs ok on my mac mini.

kind regards

Re: Pharo 6.0 and 6.1 64 bit freeze on MacMini

it may have something to do with FreeType.
Can you try removing/renaming Pharo.app/Contents/MacOS/Plugins/libFT2Plugin.dylib ?

(just to test)

thanks,

Re: Pharo 6.0 and 6.1 64 bit freeze on MacMini

Hi Esteban,

unfortunately that doesn’t make any difference.

What I did:

extension temporarily renamed to …..wasAdylib

Started Pharo app by clikcing on it (gets the downloaded maiden image)

then:

“FT2Error:Freetype2 primitive failed [error -1][can’t get error string]”

this screen dump is after maximizing Pharo

(as can be seen only dragging window redraws areas it’s been on)

didn’t freeze this time but mostly after some time it will and have to force quite Pharo.

Hi Ben,

Did the following

- restoring Pharo.app/Contents/MacOS/Plugins/libFT2Plugin.dylib (by renaming its extension back to .dylib)

- started Pharo

-setting use Free type ON

-setting Update fonts at start ON

it then immediately starts loading fonts, (which I thought might be a good idea

because perhaps fonts were not completely loaded in the image,

but that didn’t make any difference)

-saved and quit

-fired up Pharo again.

didn’t help. Same problems occur

then: (as you have asked)

- started Pharo again

-setting use Free type OFF

-setting Update fonts at start OFF

-saved and quit

-fired up Pharo again.

didn’t help either

I have no idea what the cause might be,

but if you have other suggestions to test

I be glad to help. (if not a thousand attempts :o)

in the mean time I use 5 until a next release comes out 7 ? that works ok.

Hi John,

… thanks. another wild, wild guess:

it could then perhaps be, (if Pharo uses Open GL) that my graphics

card has Open GL incompatibility? or that Pharo 6.1 uses Open GL

calls not implemented on an Intel HD Graphics 4000 chip as in my mac mini?

In reply to this post by John Pfersich

I don't think it's just on Mac Mini - my MacBook Pro late 13" 2016 retina will show similar symptoms if I try and resize the window to full screen (not the maximise button, but try and drag the bottom corner of the world to the last 5-10 pixels at the bottom of the screen).

I think Ted noticed similar in that it looks frozen but it's actually the screen not redrawing as you can fiddle to get it back (can't recall what I did - maybe drag a window on top?)

note btw in the screenshot that that some text in the dialogue boxes are not completely drawn, like

That's what I'm thinking. I'm going to do some research tonight. I'll report back what I find out.

Hi John,
… thanks. another wild, wild guess:
it could then perhaps be, (if Pharo uses Open GL) that my graphics
card has Open GL incompatibility? or that Pharo 6.1 uses Open GL
calls not implemented on an Intel HD Graphics 4000 chip as in my mac mini?

kind regards

Hi Ted,

You might consider building a debug VM. There is a random chance it provides useful insight.

At its simplest all you need to do is...

$ git clone https://github.com/OpenSmalltalk/opensmalltalk-vm.git

$ cd opensmalltalk-vm/build.macos32x86/pharo.cog.spur

$ ./mvm -A

taken from...

https://github.com/OpenSmalltalk/opensmalltalk-vm/blob/Cog/build.macos32x86/HowToBuild

First confirm the problem still exists in each of three generated VMs started normally,

then later try using lldb to trace what methods are executed.

(though I'm not familiar with lldb - you'll need to google some tutorials)

Re: Pharo 6.0 and 6.1 64 bit freeze on MacMini

But it is a freeze or a screen refresh problem?
Can you try to command . heavily on your frozen image?

Re: Pharo 6.0 and 6.1 64 bit freeze on MacMini

Within WorldState>>doOneCycle,

try writing to a file every second,

and at the command line use... tail -f ...

to see if it keeps writing when the screen is frozen.

And also try writing to a file in a forked process.

Re: Pharo 6.0 and 6.1 64 bit freeze on MacMini

Hi Stephane, Ben

In the Smalltalk world, you could value me as a relatively "simple" application developer

as a first attempt after a long time, I am trying to make
a dentist's app with Pharo Smalltalk.
(The intend is to use Smalltalk (Pharo) with Seaside and Postgress whenever possible,
because today, Smalltalk is fast enough for most applications)

At deeper levels, like working or even adequately understanding the inner workings of VMs
I virtually have no knowledge. This is not my terrain. Although this might be interesting too,
it would cost me weeks to get into that, before being able to do things like debugging VM's...

So also due to time constraints , I'd have to refrain from that, sorry,
also because I am currently working on a new version of my app RavelNotes.
This is in Swift ( i can live with that) btw, because Smalltalk is not available
for making native apps for iOS iPad. Would be an extremely daunting task
to link all iOS libs etc into Smalltalk...

cheers TedvG
