[Glass] How to debug a not responding server?

Tue Nov 12 13:44:01 PST 2013

Fist off, let's see what your server is doing, then we can discuss techniques ... 

`kill -USR1 <topaz-pid>` will cause topaz to dump a smalltalk stack so if you do this a couple of times, you'll get a sampling of what the topaz server is doing ... 

If you are not using the github repo version of Zinc, that might be your best next course of action ...

| Hi guys,

| I am trying my app for the first time. I am trying to execute the
| server start. So either from topaz or GemTools I execute (in this
| example Topaz):

| topaz 1> run

| MyRootTask initialize.
| (ZnZincServerAdaptor port: 4040)
| start.
| %
| aZnZincServerAdaptor

| But then if I try to access localhost:4040/myApp the request never
| get answered...I get no response. So...I suspect that there was an
| error in GemStone (I expect that)... but how can I see that error?
| how can I debug it?

| What I don't understand is that other type of errors I get either a
| stack pring in topaz or a debugger in GemTools, like where I was
| loading the code and there was some compiling issue...but this time
| I get nothing. What is the difference to the previous example?

| The other case is that maybe ZnZincServerAdaptor is simply frozen
| somewhere for some reason.

| If this is explained in some chapter/tutorial/post please let me
| know!

| Thanks,
