2019-02-01Revert r63383, r63248 "compile.c: copy a short insn with leave"nobu
When copying `leave` insn, TRACE also should be copied if it is present, but this optimization is trivial and not worth the complexity. [ruby-core:91366] [Bug #15578] 4cae5353c03009beb1e0a1619422072773580609 5afd479de63b6609ddcd1510da94d2c1ac384f7f git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66977 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2019-01-01compile.c (iseq_set_sequence): fix branch coverage tablemame
Not only TRACE_ELEMENT but also INSN_ELEMENT may have events. The old pc2branchindex was created using only events of TRACE_ELEMENTs. This change uses events of INSN_ELEMENTs too for pc2branchindex table. [Bug #15476] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66676 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-12-20ext/coverage/lib/coverage.rb (Coverage.line_stub): use only line eventsmame
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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66468 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-10-20ext/coverage/: add the oneshot modemame
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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65195 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-08-22compile.c: remove tracecoverage instruction for line coveragemame
Line coverage was based on special instruction "tracecoverage". Now, instead, it uses the mechanism of trace hook [Feature #14104]. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64509 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-08-22parse.y: remove coverage-related code fragmentsmame
The code fragments that initializes coverage data were scattered into both parse.y and compile.c. parse.y allocated a coverage data, and compile.c initialize the data. To remove this cross-cutting concern, this change moves the allocation from "coverage" function of parse.y to "rb_iseq_new_top" of iseq.c. For the sake, parse.y just counts the line number of the original source code, and the number is passed via rb_ast_body_t. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64508 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-12-18iseq.c (finish_iseq_build): fix coverage leakage [Bug #14191]mame
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. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61313 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-12-05Revamp method coverage to support define_methodmame
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`). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61023 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-09-02test/coverage/test_coverage.rb: run the tests in separated processesmame
The tests had been disabled under coverage measurement (during `ENV['COVERAGE']`), since they call `Coverage.result` which stops coverage measurement. So, we couldn't measure both C-level and Ruby-level coverage of Ruby simultaneously. In short, `./configure --enable-gcov && make exam COVERAGE=true` misses some coverages. Now, the test runs in another process. They does not stop coverage measurement, so we can now enable the tests under coverage measurement. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59724 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
