I looked at my MIB/ASN.2 compiler I wrote in Perl, and the results are interesting. But most of the code I want to look at are CGI’ish stuff. How would I get NYTProf to profile their execution?

It’ll have to wait for a blog post though. Most of the discussion took place on the (unarchived) plsql-security list. The final patch is here if you’d like to dig that deep.

I wasn’t clear on that myself. The confusion arose because use_db_sub=1 does allow old versions of perl to record the “perl -e …” and “perl -” source code. I’ve added an update to the blog post and I’ll make a 4.01 release soon. Thanks for prompting me to clarify this!

Anyway, on perl 5.10 it works perfectly.

I’m using 5.8.8 (system perl from ubuntu hardy).

But use_db_sub=1 doesn’t seem to have any effect…

Did you read the savesrc section in the documentation and try using the use_db_sub=1 option that it recommends?

Thanks for your great work, this is a really exciting feature which i wanted for a very long time.

But it strangely doesn’t work for me, generated report contains this comment:
> No source code available for string eval (eval 50)[lib/PPB/Join/Abstract.pm:151].
> See savesrc option in documentation.
And after that, many lines with times and “spent XXX ms making XXX calls” comments, but all code lines are empty.

Am I missing something?
