Subject: [ruby-dev:50622] [Ruby trunk Bug#14817] TracePoint#parameters for bmethod's return event should return the same value as its Method#parameters
Date: Thu, 23 Aug 2018 07:10:51 +0000 (UTC) [thread overview]
Message-ID: <redmine.journal-73669.20180823071050.625a68cccd740c5d@ruby-lang.org> (raw)
In-Reply-To: redmine.issue-14817.20180603144747@ruby-lang.org
Issue #14817 has been updated by ko1 (Koichi Sasada).
見逃してました。
これ、実装見てたら、どーしょーもない気がするんで、制限のある仕様、ってことで駄目でしょうか。駄目かなあ。実装アイディア募集。
----------------------------------------
Bug #14817: TracePoint#parameters for bmethod's return event should return the same value as its Method#parameters
https://bugs.ruby-lang.org/issues/14817#change-73669
* Author: ktsj (Kazuki Tsujimoto)
* Status: Assigned
* Priority: Normal
* Assignee: ko1 (Koichi Sasada)
* Target version: 2.6
* ruby -v: ruby 2.6.0dev (2018-06-03 master 63562) [x86_64-linux]
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN
----------------------------------------
define_methodしたメソッド(bmethod)のcall/returnイベント中にTracePoint#parametersを呼び出すと
以下の結果となります。
```
$ cat t.rb
define_method(:bm) {|a|}
p method_parameters: method(:bm).parameters
trace = TracePoint.new(:call, :return){|tp|
mid = tp.method_id
if mid == :bm
p mid: mid, event: tp.event, tp_parameters: tp.parameters
end
}
trace.enable{
bm(0)
}
$ ruby -v t.rb
ruby 2.6.0dev (2018-06-03 master 63562) [x86_64-linux]
{:method_parameters=>[[:req, :a]]}
{:mid=>:bm, :event=>:call, :tp_parameters=>[[:req, :a]]}
{:mid=>:bm, :event=>:return, :tp_parameters=>[]} #=> expected: {:mid=>:bm, :event=>:return, :tp_parameters=>[[:req, :a]]}
```
現状、callイベントに限ってその戻り値がbmethodのMethod#parametersの呼び出し結果と一致しますが
returnイベント時も同様となるべきだと思います。
