Hello all,
I am developing Dtrace Support on JRUby as my GSOC project. In my project I
am planning to add following DTrace probes to JRuby.
· 1. Object-create -: fired when an object is about to allocated
· 2. Array-create -: fired when an Array is about to be allocated
· 3. Hash-create -: fired when an Hash is about to allocated
· 4. String-create -: fired when String is about to allocated
· 5. Symbol-create -: fired when symbol is about to be allocated
· 6. Parse-begin -: fired just before parsing and compiling a
source file
· 7. Parse-end –: fired just after parsing and compiling a source
file
· 8. method-entry -: Fired just before a method is entered.
· 9. method-return -: Fired just after a method has returned.
· 10. Load-entry -: fired when calls to “load” are made
· 11. Load-return -: fired when load returns.
· 12. Raise –: fired when an exception is raised
· 13. Java-method-entry -: fired just before a Java method is
entered
· 14. Java-method-return -: fired just before Java method is
returned
· 15. Require-entry -: fired on calls to rb_require_safe
· 16. Require-return -: fired just before rb_require_safe returns
· 17. Find-require-entry -: fired just before search_required is
called
· 18. Find-require-return -: fired just after search_required
returns
· 19. Gc-mark-begin -: fired at beginning of mark phase
· 20. Gc-mark-end -: fired at the end of mark phase
· 21. Gc-sweep-begin -: fired at the beginning of a sweep phase
· 22. Gc-sweep-end -: fired at end of sweep phase.
To add these probes I need to find places in JRuby codes to add these
probes, so they will execute their desired task. Since I am not much
familiar with JRuby code, if you can give me some help to find the places
to add these probes, it will be very helpful for getting this to work
quickly.
-Regards
