* compile.c: avoid newarraykwsplat for argumentsv2_7_0_rc2Yusuke Endoh2019-12-221-0/+6
| | | | | | | | | | | | | | `foo(*rest, post, **empty_kw)` is compiled like `foo(*rest + [post, **empty_kw])`, and `**empty_kw` is removed by "newarraykwsplat" instruction. However, the method call still has a flag of KW_SPLAT, so "post" is considered as a keyword hash, which caused a segfault. Note that the flag cannot be removed if "empty_kw" is not always empty. This change fixes the issue by compiling arguments with "newarray" instead of "newarraykwsplat". [Bug #16442]
* Should return "." for File.extname("file.") also on WindowsNAKAMURA Usaku2019-12-222-8/+4

* Kernel#lambda: return forwarded block as non-lambda procAlan Wu2019-12-211-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | Before this commit, Kernel#lambda can't tell the difference between a directly passed literal block and one passed with an ampersand. A block passed with an ampersand is semantically speaking already a non-lambda proc. When Kernel#lambda receives a non-lambda proc, it should simply return it. Implementation wise, when the VM calls a method with a literal block, it places the code for the block on the calling control frame and passes a pointer (block handler) to the callee. Before this commit, the VM forwards block arguments by simply forwarding the block handler, which leaves the slot for block code unused when a control frame forwards its block argument. I use the vacant space to indicate that a frame has forwarded its block argument and inspect that in Kernel#lambda to detect forwarded blocks. This is a very ad-hoc solution and relies *heavily* on the way block passing works in the VM. However, it's the most self-contained solution I have. [Bug #15620]

* Make super in instance_eval in method in module raise TypeErrorJeremy Evans2019-12-121-0/+23
| | | | | | | | | | | | | | | | | | | | | | | This makes behavior the same as super in instance_eval in method in class. The reason this wasn't implemented before is that there is a check to determine if the self in the current context is of the expected class, and a module itself can be included in multiple classes, so it doesn't have an expected class. Implementing this requires giving iclasses knowledge of which class created them, so that super call in the module method knows the expected class for super calls. This reference is called includer, and should only be set for iclasses. Note that the approach Ruby uses in this check is not robust. If you instance_eval another object of the same class and call super, instead of an TypeError, you get super called with the instance_eval receiver instead of the method receiver. Truly fixing super would require keeping a reference to the super object (method receiver) in each frame where scope has changed, and using that instead of current self when calling super.

* Fix Enumerator::Lazy#with_indexJeremy Evans2019-12-111-2/+15
| | | | | | | | | | | | | | | | * Make it correctly handle lambdas * Make it iterate over the block if block is given The original implementation was flawed, based on lazy_set_method instead of lazy_add_method. Note that there is no implicit map when passing a block, the return value of the block passed to with_index is ignored, just as it is for Enumerator#with_index. Also like Enumerator#with_index, when called with a block, the return value is an enumerator without the index. Fixes [Bug #16414]
* test/ruby/test_keywords.rb: suppress a warningYusuke Endoh2019-12-101-1/+1
| | | | | | | https://rubyci.org/logs/rubyci.s3.amazonaws.com/ubuntu1604/ruby-master/log/20191210T003005Z.log.html.gz ``` .../test/ruby/test_keyword.rb:2711: warning: `*' interpreted as argument prefix ```
* Add Proc#ruby2_keywordsJeremy Evans2019-12-091-0/+39
| | | | | | | | | | | | This allows passing keywords through a normal argument splat in a Proc. While needing ruby2_keywords support for methods is more common, there is code that delegates keywords through normal argument splats in procs, including code in Rails. For that reason, it makes sense to expose this for procs as well. Internally, ruby2_keywords is not tied to methods, but iseqs, so this just allows for setting the ruby2_keywords for the iseq related to the proc.

* Make Enumerator::Chain#each treat lambdas as lambdaJeremy Evans2019-12-031-0/+16
| | | | | | | | Previously, lambdas were converted to procs because of how rb_block_call works. Switch to rb_funcall_with_block, which handles procs as procs and lambdas as lambdas. Fixes [Bug #15613]
* Do not lose existing constant visibility when autoloadingJeremy Evans2019-12-031-0/+60
| | | | | | | | | | This copies the private/deprecate constant visibility across the autoload. It still is backwards compatible with setting the private/deprecate constant visibility in the autoloaded file. However, if you explicitly set public constant in the autoloaded file, that will be reset after the autoload. Fixes [Bug #11055]
