hangs (hot) when selecting large character string temps in debugger ... #47

Open dalehenrich opened 7 years ago

dalehenrich commented 7 years ago

I actually cannot tell how big the string is .. yet, but I assume that it is large, because I ran out of memory in the gem when I first tried selecting auditResult ... I've tried trimming the size to 2000 characters and it still hangs ...

I also bumped the temp obj cache to a large size (2G) ... hmmmm now I see that pharo is running hot ...

dalehenrich commented 7 years ago

The original auditResult string is 1092571 characters in size ..

Looks like gt4gemstone might be in an infinite loop for some kind or error. Here's as much of the pharo stack that gets copied when I interrupt the client:

It is entirely possible that the original server-side auditResult string is a Unicode32 string. We are auditing unicode indexes with randomly generated strings ... got to go to plan B right now, because I need to see the audit result string...

This is the output that I get from topaz (truncated at some point), but it doesn't look like unicode is involved:

Just tried the following and the Inspector&Debugger look fast so the error seems to be related to the actual String:

 | string |  
 string := String new: 1092571.
 1 to: 1092571 do: [ :index |
      string at: index put: $a ].
 self halt.
 string.

When I need to debug recursion errors I usually put a self halt at the beginning of GtGsMinimalClient>>#debuggerRequested:. The fist time I hit proceed and the second time the error will be related to the debugger. Now manually executing GtGsGenericStackDebugger openBasicStackViewerFor: gsNotification from: self (like if GtGsGenericStackDebugger useBasicStackViewer answers true) should just open with a transcript showing the stack frames. If you could paste that output it will help to understand what is the error in the debugger.

second halt yields: a MessageNotUnderstood occurred (error 2010), a QuadByteString does not understand #'truncateWithElipsisTo:' ... this looks like a method that is available in GsDevKit/GLASS/tODE, but not the base ...

chisandrei commented 7 years ago

Ahh, yes that's the bug. The inspector extension for String objects (CharacterCollection>>gtGsInspectorAATextIn:) uses it. I guess I'll add a CharacterCollection>>#gtGsTruncateWithElipsisTo:
