ext/coverage/lib/coverage.rb (Coverage.line_stub): use only line events

2018-12-20T10:17:37+00:00

It wrongly used all linenos of ISeq#trace_points which includes not only
line events but also call, return, and other events.  So, the result
included some linenos that can not be covered at all by line coverage.

ext/coverage/: add the oneshot mode

2018-10-20T05:33:04+00:00

This patch introduces "oneshot_lines" mode for `Coverage.start`, which
checks "whether each line was executed at least once or not", instead of
"how many times each line was executed".  A hook for each line is fired
at most once, and after it is fired, the hook flag was removed; it runs
with zero overhead.

See [Feature #15022] in detail.

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`).
