[Glass] tools/objectLog web tool and stack traces?

I use Jade (on Windows) to look at the object log. There is a menu option on the Transcript for ‘Browse Object Log (<Ctrl>+<L>)’. This opens a debugger on the stack so you can inspect the stack frames. You can’t however, edit and continue.

Hi guys,

I was quite amazed with GemTools and how I could debug my local gemstone. But when I tried to connect to a remote instance, I understood what you said it was slow ;)

So for the "porting" of my app, I have no problem because I can do everything with my local gemstone and then with topaz and metacello I load stuff in my remote gemstone.

But there is one thing I miss about GemTools and a remote instance: debug problems. I know I could copy the extents to my machine and debug it here, but moving the extents over the wire can take me several hours. 

So....I wonder, which are all possibilities we have to debug a problem in a remote GemStone? Say a typical seaside walkback. 

1) I guess logs. I am still a bit lost in which log the stack traces of an error is stored. I checked in /opt/gemstone and I don't seem to find them. I am talking about something like the PharoDebug.log

2) ObjectLog. I saw there is a web tool WAObjectLog but I can see only the log..I cannot seem to see the stack traces

Since I am still porting the app, it is likely most of my problems will be DNUs or something like that. So it is likely that a simple stack trace would help.

But...say that at some point I would really like to really debug it, which options do I have besides copying the extens to my local gemstone?

Dale, is it tODE ready for this? (debug from the Object Log)

Thanks in advance for any help!

tODE can't debug and restart errors that happened in other gems that are on
the object log.  See this issue:

https://github.com/dalehenrich/tode/issues/39

You can inspect the stack though.



I sometimes use GemTools on the remote server and use ssh -X forwarding to
get the GUI.  Its faster than local GemTools + remote GemStone because only
the X11 stuff is sent over the wire.  See here:

Its tolerable for sure.
