[OPEN-ILS-DEV] Evergreen debugged tutorial for your evaluation

[Kivilahti Olli-Antti]

Hi all.

I have been cracking my head to OpenSRF these past few days trying to 
bring the Perl debugger to debug OpenSRF's Evergreen services, like 
open-ils.serial.
with success...

Thanks to the help of community members and divine justification, I have 
been writing a tutorial about my experiences so others could aim their 
debuggers at Evergreen.
You can read and comment here:

Currently it has been marginally tested, but it works for me as well as 
a perl -d can.

I hope you find something to nag about.

Sincerely yours,
Olli-Antti Kivilahti

I then I use "dropdb evergreen" and then pg_restore[2] on the test VMs. On occasion I get an error message of "segmentation fault" when I try to run pg_restore[2] on the test VM, but usually I don't have any issues. Before I got this error today, I did a pg_dump of the concerto data that was already on the VMs postgres, and as a test I successfully used pg_restore to reload the concerto data with out any problems. Except for some warning I usually get when I successfully run pg_restore[3]. Finally, I checked /var/log/postgresql/postgresql-9.1-main.log and only saw entries for the warnings I just mentioned from when I restored up the concerto data as a test.
