* Document Different Coverage ModesKevin Murphy2020-11-201-1/+111
| | | | | | | This commits adds in documentation to illustrate the different modes you can start coverage with. Examples are provided to show how to start each of these modes, along with an explanation of the mode and a description of the output.

* RHASH_TBL: is now ext-only卜部昌平2020-08-191-1/+2
| | | | | It seems almost no internal codes use RHASH_TBL any longer. Why not just eliminate it entirely, so that the macro can be purely ext-only.
* compile.c: Improve branch coverage instrumentation [Bug #16967]Yusuke Endoh2020-06-201-26/+52
| | | | | | | | | | | | | | Formerly, branch coverage measurement counters are generated for each compilation traverse of the AST. However, ensure clause node is traversed twice; one is for normal-exit case (the resulted bytecode is embedded in its outer scope), and the other is for exceptional case (the resulted bytecode is used in catch table). Two branch coverage counters are generated for the two cases, but it is not desired. This changeset revamps the internal representation of branch coverage measurement. Branch coverage counters are generated only at the first visit of a branch node. Visiting the same node reuses the already-generated counter, so double counting is avoided.
* decouple internal.h headers卜部昌平2019-12-261-1/+3
| | | | | | | | | | | | | | | | | | Saves comitters' daily life by avoid #include-ing everything from internal.h to make each file do so instead. This would significantly speed up incremental builds. We take the following inclusion order in this changeset: 1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very first thing among everything). 2. RUBY_EXTCONF_H if any. 3. Standard C headers, sorted alphabetically. 4. Other system headers, maybe guarded by #ifdef 5. Everything else, sorted alphabetically. Exceptions are those win32-related headers, which tend not be self- containing (headers have inclusion order dependencies).
* Revert https://github.com/ruby/ruby/pull/2486卜部昌平2019-10-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commits: 10d6a3aca7 8ba48c1b85 fba8627dc1 dd883de5ba 6c6a25feca 167e6b48f1 7cb96d41a5 3207979278 595b3c4fdd 1521f7cf89 c11c5e69ac cf33608203 3632a812c0 f56506be0d 86427a3219 . The reason for the revert is that we observe ABA problem around inline method cache. When a cache misshits, we search for a method entry. And if the entry is identical to what was cached before, we reuse the cache. But the commits we are reverting here introduced situations where a method entry is freed, then the identical memory region is used for another method entry. An inline method cache cannot detect that ABA. Here is a code that reproduce such situation: ```ruby require 'prime' class << Integer alias org_sqrt sqrt def sqrt(n) raise end GC.stress = true Prime.each(7*37){} rescue nil # <- Here we populate CC class << Object.new; end # These adjacent remove-then-alias maneuver # frees a method entry, then immediately # reuses it for another. remove_method :sqrt alias sqrt org_sqrt end Prime.each(7*37).to_a # <- SEGV ```
* refactor constify most of rb_method_entry_t卜部昌平2019-09-301-1/+1
| | | | | | | | | | | Now that we have eliminated most destructive operations over the rb_method_entry_t / rb_callable_method_entry_t, let's make them mostly immutabe and mark them const. One exception is rb_export_method(), which destructively modifies visibilities of method entries. I have left that operation as is because I suspect that destructiveness is the nature of that function.

* ext/coverage/: add the oneshot modemame2018-10-201-12/+49
| | | | | | | | | | | | 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

* Revamp method coverage to support define_methodmame2017-12-051-21/+74
| | | | | | | | | | | | | | 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

* [EXPERIMENTAL] Extend the API of `Coverage.start` and `result`mame2017-09-141-8/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | The old API: Coverage.start load "foo.rb" p Coverage.result #=> {"foo.rb" => [1, 2, nil]} The new API: ENV["COVERAGE_EXPERIMENTAL_MODE"] = "true" Coverage.start(lines: true) load "foo.rb" p Coverage.result #=> {"foo.rb" => {:lines => [1, 2, nil]}} This new API allows us to add other measuring target types. Notes: * To keep compatibility, the old interface is still remained; passing no optional argument makes `Coverage.result` return the old format. * This feature is still experimental. So, to enable the new API, the environment variable `COVERAGE_EXPERIMENTAL_MODE` must be set. I plan to activate this feature by Ruby 2.5. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59874 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | | | To prepare new measuring targets: branch and method coverages. So far, iseq->coverage was an array of counts executed for line coverage. Now, it is a three-element array for each measuring target, whose first element is an array for line coverage.

This change is a part of RGENGC branch [ruby-trunk - Feature #8339]. * object.c: add new function rb_obj_reveal(). This function reveal interal (hidden) object by rb_obj_hide(). Note that do not change class before and after hiding.

TODO: modify constified variables using cast may be harmful for compiler's analysis and optimizaton. Any idea to prohibt inserting RBasic::klass directly? If rename RBasic::klass and force to use RBASIC_CLASS(obj), then all codes such as `RBASIC(obj)->klass' will be compilation error. Is it acceptable?
