[ruby-core:92482] [Ruby trunk Bug#15810] Windows spec failure - Process.ppid returns the process id of the parent of this process - ??

[usa@garbagecollect.jp]

Issue #15810 has been updated by usa (Usaku NAKAMURA).

Status changed from Open to Closed

in `test-spec` target of make, `RUBY_EXE` constant in mspec is `RUNRUBY`.
it means that the invoked ruby process is the grandchild of the invokee, not the child.
so, this spec is never passed on Windows via `make test-spec`.

Bug #15810: Windows spec failure - Process.ppid returns the process id of the parent of this process - ??
https://bugs.ruby-lang.org/issues/15810#change-77828

* Author: MSP-Greg (Greg L)
* Status: Closed
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: 
* Backport: 2.4: UNKNOWN, 2.5: UNKNOWN, 2.6: UNKNOWN
----------------------------------------
Since being committed at 79671ec on 28-Apr, this spec has consistently failed:

```
Process.ppid returns the process id of the parent of this process FAILED
Expected "11424\n"
 to equal "13044\n"

C:/projects/ruby/spec/ruby/core/process/ppid_spec.rb:5:in `block (2 levels) in <top (required)>'
C:/projects/ruby/spec/ruby/core/process/ppid_spec.rb:3:in `<top (required)>'
```

But, testing it locally, both 'serial' & parallel, it passes.  The test also passes at ruby/spec, and it passed with ruby-loco (which doesn't use make)...

As to testing locally, if anyone wants to verify (on Windows), from the `spec/ruby` folder:

```
../mspec/bin/mspec -rdevkit  -j -T "--disable=gems" core
```
