Pharo 6 vm crashed when pasting a big file

by tdupriez＠ens-paris-saclay.fr

Hi, The pharo 6 vm crashed when I pasted a long text file in the body of a method. Surprisingly, the vm did not crashed when I pasted a file of approximately the same size but only containing a single string ('adafcawa' copy-pasted on 8000 lines). The crash occured after I: - Opened a fresh image (60450) - Created a package, with a single class, with a single method - Tried to paste the content of the attached file into the methods body (the vm froze for 20-30 seconds then crashed) Ubuntu 16.04 LTS 64 bits vm obtained from http://get.pharo.org/ (the '60+vm' package) image 60450 Thomas

More Windows VM Crashing -_-

by Peter Uhnak

Hi, Originally I thought my VM is crashing because of FT, so I applied some fix from FogBugz (that is now part of Pharo 6), but that didn't help. So I disabled FT in settings and changed fonts to non-FT ones; didn't help. So I completely removed FT2Plugin.dll (now settings just states that FT fonts are not available), but that didn't help either. And obviously there is no crash.dmp whatsoever (this is latest Windows VM). This crash is extremely frustrating because the crash happens _during saving_, which means I am losing code all the time and have to constantly recover them, which really makes my blood boil. Without crash dump I don't even know where and how to start investigating. Windows kindly opens Visual Studio when Pharo crashes, but all it shows to me is assembly, which is not very useful to me. I can somewhat orient myself in the C code of the VM (as I've alredy fixed some other issues in the VM), but here I am lost. <SNIP> 00407D7F ret 00407D80 mov eax,dword ptr ds:[00596E44h] 00407D85 test al,3 00407D87 jne 00407DB2 00407D89 mov ecx,dword ptr ds:[596E08h] 00407D8F lea edx,[ecx-1] 00407D92 cmp eax,edx 00407D94 jb 00407DB2 00407D96 cmp dword ptr ds:[596E10h],eax 00407D9C jb 00407DB2 00407D9E mov ecx,dword ptr ds:[5B89D0h] 00407DA4 cmp dword ptr [eax-4],ecx 00407DA7 jb 00407DB2 00407DA9 mov eax,dword ptr ds:[00596E28h] ---> 00407DAE movzx eax,byte ptr [eax] 00407DB1 ret eax = 00000000 ecx = 04700000 </SNIP> So my question I guess is: How can we fix this? How can I help fix this? Because I've lost countless days of time and energy on this f***ing problem... Peter

Collecting of event data still needed?

by Pavel Krivanek

>From a Slack discussion: Alexandre Bergel [6:03 PM] @uko : Do we still need the usage data ? Alexandre Bergel [6:03 PM] Having this large red bar is a bit aggressive Yuriy Tymchuk [6:06 PM] Data is always useful. Now as I end my Ph.D. I will not have time to investigate the collected data any more, so the question is does anybody else care about the collected data, because yes, I can just remove it. By the way, I just reuse the morph from Spotter, so it is up to them to define the style :slightly_smiling_face: - So the question is: do we still need to display appeal for sending usage data in Pharo 7? Is anyone analyzing it or do we only irritate users? Such request can be in the Welcome window. Cheers, -- Pavel
