Bug #4991: Add a method to retrieve raw data from GC::Profiler

• Status: Closed
• Assignee: ko1 (Koichi Sasada)

[drbrain (Eric Hodel)]

GC::Profiler.result gives a String report but there is no access to the raw profile data. There is no way to extract data for automatic comparison without parsing the output String.

The attached patch adds GC::Profile.data which exposes gc_profile_record_get.

This allows tools that can automatically compare profile runs to be written without parsing.

Hi.

In fact, i proposed GC::Profiler.data at 2008/7/26 on ruby-core ML.
But it's rejected, because matz said "more appropriate name" to me.

Ok, some other ideas then:

records
stats
runs
results (although there is result already)
log
history
raw_data
raw

Any sound good?

I like GC::Profiler.raw_data.

Matz, What do you think?
