iseq.c (finish_iseq_build): fix coverage leakage [Bug #14191]

2017-12-18T02:44:36+00:00

Before this change, coverage.so had failed to measure some multiple-line
code fragments.  This is because removing trace instructions (#14104)
changed TracePoint's lineno (new lineno), and coverage counter array was
based on old lineno.
This change initializes coverage counter array based on new lineno.

ext/coverage/coverage.c: method coverage has column info. of method def.

2017-12-05T08:56:51+00:00

This change makes method coverage result have not only first lineno of
method defintion, but also code range (i.e. first lineno, first column,
last lineno, and last column).

Revamp method coverage to support define_method

2017-12-05T07:16:42+00:00

Traditionally, method coverage measurement was implemented by inserting
`trace2` instruction to the head of method iseq.  So, it just measured
methods defined by `def` keyword.

This commit drastically changes the measuring mechanism of method
coverage; at `RUBY_EVENT_CALL`, it keeps a hash from rb_method_entry_t*
to runs (i.e., it counts the runs per method entry), and at
`Coverage.result`, it creates the result hash by enumerating all
`rb_method_entry_t*` objects (by `ObjectSpace.each_object`).
