[Bug in 7.8] VW keeps on breaking on OSX

Hi,

My 7.8 images keep on breaking without reason (once every 15 minutes), It often happen when doing (starting) some database operations (PostgreSQL in this case) but nothing is really clear about it. I use Cairo but it doesn't necessarily seem to be related to that either.

Just report it, enclosed is the OSX report, maybe someone else has similar experiences ?

@+Maarten,

Well, the dump clearly shows that is the the cairo library that called abort()....

13 com.cincom.vw7.8 0x0000bafa primCallVarArgC + 332 (exCallC.c:507)

Can it be that your image holds stale cairo objects (that in turn could contain stale pointers not cleaned by the image/dllcc startup code)?

Re: [Bug in 7.8] VW keeps on breaking on OSX

I'm at SPLASH/OOPSLA right now (like.. RIGHT now), but I'll try and take a look this week if Travis doesn't beat me to it (I suspect he will, he's pretty darn fast).

Please let us know what version of CairoGraphics you're using in 7.8 -- both the smalltalk package version and which libraries you're using (the ones Travis shipped or your own compiled ones).

Re: [Bug in 7.8] VW keeps on breaking on OSX

SPLASH/OOPSLA that must be a cool place to be !!

Anyway this a plain 7.8 image with Cairo 7.9 - 2, I did not install any specific Cairo/Pango Library so I suppose it uses the ones which are shipped with the product.

I'am upgrading to 7.9 sta oct 11.3 right now to see wheter this makes a difference.

Re: [Bug in 7.8] VW keeps on breaking on OSX

You're going to need to track down the place where you're drawing text with Cairo, because, at a glance, it looks like it must be an invalid font name or font name / style / size combination causing the problem.

Re: [Bug in 7.8] VW keeps on breaking on OSX

Well the font type is set either through:

selectFontFace: aFaceName

selectFontFace: aFaceName slant: aFontSlant weight: aFontWeight

If I apply something like:

selectFontFace: aFaceName slant: aFontSlant weight: aFontWeight

" LibCairo

cairo_select_font_face: handle

with: aFaceName

with: aFontSlant

with: aFontWeight .

self checkStatus "

Cairo is normally obliged to take its default font everywhere in my App.

Just notice that in the current version of Cairo it is not yet possible to query the system for its available fonts and I have no idea what fonts are actually supported by Quartz.

Anyway the above doesn't help, it still breaks after some time.

Re: [Bug in 7.8] VW keeps on breaking on OSX

In reply to this post by Maarten Mostert

Ok, I now tried the following override for a while.

In CairoContext

fontSize: aFontSize

LibCairo cairo_set_font_size: handle with: (11) dllccDouble.

self checkStatus

selectFontFace: aFaceName slant: aFontSlant weight: aFontWeight

LibCairo

cairo_select_font_face: handle

with: 'Arial'

with: aFontSlant

with: aFontWeight .

self checkStatus

This seems to work a little bit longer but I started from a fresh image. I think my image lasted for almost 2 hours before breaking down.

Very difficult however to specify something more common then an Arial 11 font....
