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).

vm_core.h (rb_iseq_locatoin_t): add a field `code_range`

2017-12-05T08:56:50+00:00

This change makes each ISeq keep NODE's code range.  This information is
needed for method coverage.

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`).

ext/coverage/coverage.c (rb_coverage_start): Ensure `opt` is a hash

2017-09-15T00:40:38+00:00

Ensure `opt` is a hash before using `rb_hash_lookup` to `opt`.
This will prevent SEGV when an inappropriate object (i.e. an array)
is passed to `opt`.

ext/coverage/coverage.c: use long instead of int for coverage site id

2017-09-14T10:45:04+00:00

Coverage generates unique ID numbers for each branch and each method.
Use long instead of int for the IDs.  I don't want to see 2^32 branches
and methods in one file, but just in case...
