[ruby-dev:50095] [Ruby trunk Bug#13489][Open] "make test-all" fails on macOS with case-sensitive filesystem

Issue #13489 has been updated by watson1978 (Shizuo Fujita).

Status changed from Closed to Open

まだ、以下のテストが  case-sensitive filesystem で通らないのでチケットを再オープンいたします。
(該当箇所は https://github.com/ruby/ruby/blob/9c5c31c8b70106989a218e41935c0ab75f631b34/test/ruby/test_file_exhaustive.rb#L743-L757 です)

```
$ make test-all -j 8

make: *** [yes-test-all] Error 1
```

どうやら Kernel.open の振る舞いが case-sensitive と非 case-sensitive で違うようです。

```ruby
regular_file = "file.test"
system "touch #{regular_file}"

c = "\u{feff}"
file = regular_file + c
begin
  open(file) {}
  puts "** Success **"
rescue
  puts "** Exception **"
end
```

外付けのドライブを 非 case-sensitive でフォーマットしそこで実行すると、以下のようにファイルがオープンできています。

```
$ ruby -v test_file.rb
ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-darwin16]
** Success **
```


case-sensitive な内蔵ディスク上で実行すると、以下のようにファイルに失敗しています。

```
$ ruby -v test_file.rb
ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-darwin16]
** Exception **
```

この振る舞いの違いは Kernel.open の不具合なのかと推測しておりますが、いかがでしょうか。

https://bugs.ruby-lang.org/issues/13489#change-64434

* Author: watson1978 (Shizuo Fujita)

----------------------------------------
普段使用している macOS は HFS+ case-sensitive でフォーマットしています。
"make test-all" をそのマシン上で実行すると以下のようなエラーが発生し、
どうやら conftest.c でのコンパイルエラーが原因のようです。

conftest.c には

~~~
#include <Ruby/Ruby.h>
~~~

 という行が生成されるらしいのですが、
case-sensitive なファイルシステムではそのファイルパスを見つけることができません。

~~~
#include <ruby/ruby.h>
~~~
と生成されるべきかと思います。

https://github.com/ruby/ruby/blob/3e92b635fb5422207b7bbdc924e292e51e21f040/test/mkmf/test_framework.rb#L24-L33
の have_framework("Ruby") でinclude文が生成されているのかと思われます。
