続: インスタンス オブジェクトを消したい

インスタンス オブジェクトを消したい - よくきたはてダ でいろいろコメントをいただいたので，ご提示いただいたサンプルをなぜ使わなと考えるかを一応書いておきます．

元ネタは「インスタンス オブジェクトを今すぐ消したいんだけど!!」という話です．

っで，いただいたコメントから取り上げるのはこの辺．

見返してみると何かプロパティとして入れておかないと有難味は分からないですね。この技は明示的に循環参照を切るときに使います。

結論から言うと，すみませんが今のところオブジェクトを消すためにご提示いただいた手法は個人的には公私共に利用することはないと思います#特に仕事だと何らかの権限の方から「使え」といわれるとまた別の判断もあると思いますけど

今回改めて取り上げるのはいただいたコードのひとつ，

use Data::Dumper;

package foo;
sub new { $class = shift; bless {}, $class;}
sub DESTROY { print "bye!\n"; }

package main;
$obj = new foo;
print Dumper($obj);
%$obj = ();
print Dumper($obj);

です．たぶん上鍵の推測ではこれは(上鍵の)期待通りに動いていないと思ったので，検証するために簡単に編集してみました。

#ちなみにこの「期待通り」は「こういう結果であってほしい」であって厳密にはperlの仕様どおりとしての期待通りという意味ではないです．念のため

use Data::Dumper;

package foo;
sub new { $class = shift; bless {}, $class;}
sub DESTROY { print "bye!\n"; }

package main;
$obj = new foo;
print Dumper($obj);
%$obj = ();
print Dumper($obj);

こちら差分．

$ perl p9b.pl
$VAR1 = bless( {}, 'foo' );
$VAR1 = bless( {}, 'foo' );
foo

予想通り実行できてしまいました．ちなみに別にご提案いただいたundefだとエラーになります．

use Data::Dumper;

sub DESTROY { print "bye!\n"; }

こちら期待通りです

$ perl p9c.pl
$VAR1 = bless( {}, 'foo' );
bye!
$VAR1 = undef;
Can't call method "foo" on an undefined value at p9c.pl line 13.

ということで簡単ですがこれにて．

インスタンス オブジェクトを消したい

そろそろPerl暦1ヶ月になりそうです．たぶん初めてのPerlエントリー!! さてメモ．
Perlでインスタンスしたオブジェクトをとある事情で明示的に消したいと思ったわけですよ．

#その後こういう実装は不要になるようにしたわけですが

@elf undef $object;で解決では？

試してみた．

$ perl -e 'use Data::Dumper; package foo; sub new { $class = shift; bless {}, $class;} sub DESTROY { print "bye!\n"; }package main; $obj = new foo; print Dumper($obj); undef $obj; print Dumper($obj);'
$VAR1 = bless( {}, 'foo' );
bye!
$VAR1 = undef;

表面的には期待通りの挙動に見える．これ以上深耕するスキルがないのが悔しい．しいていうとperldocいわく

undef EXPR

undef
Undefines the value of EXPR, which must be an lvalue. Use only on a
scalar value, an array (using @
), a hash (using %
), a subroutine
(using &
), or a typeglob (using *
).

だそうな．オブジェクトについては明記されていないように見える．

@elf %$self = ()

コードとしてないわーですが，

#ふつーオブジェクトの削除ではなく，ハッシュの初期化として読むでしょ(んなことないのがPerlの世界?

$ perl -e 'use Data::Dumper; package foo; sub new { $class = shift; bless {}, $class;} sub DESTROY { print "bye!\n"; }package main; $obj = new foo; print Dumper($obj); %$obj = {}; print Dumper($obj);'
$VAR1 = bless( {}, 'foo' );
$VAR1 = bless( {
                 'HASH(0x9cd90ac)' => undef
               }, 'foo' );
bye!

挙動としてもないわー．

とりあえず記載されていなそうだし実際問題既に不要な話なんだけど，どこの辺をぼちぼち読んでみます

Cacti Plugin Architecture Upgrade Information

Change to global.php and config.php

For legacy plugins, those that must be installed in global.php, we have moved the plugins array out of global.php and into config.php. This was done to insure that global.php remains pristine. It is a file that is not intended to be modified, so with the PIA installed, you should not have to.

The variable "URL_PATH" has also been moved from global.php to config.php for the same reason as the plugins array. For those of you upgrading from very old Plugin Architectures you should know that in the past, we attempted to "detect" this path. However, the process was not reliable. Therefore, you have to specify that path in config.php.

Visual Changes in Cacti

Visual changes will not impact the functionality of existing plugins. However, due to some poor practices, some of the page rendering may be a bit off.

To address this issue, The Cacti Group has prepared releases of approximately 17 existing plugins in our stable of addon's to maintain a consistent look and feel.

There has been quite a bit of work put into these updated plugins. If you find that there is a feature that you want or need that did not make it into an updated plugin, please open a feature request at http://www.cacti.net/bugs.php .

Changes to Cacti's Core

There are two changes in the Core of Cacti that will affect some plugins. The first change is that we have provided RRDtool segfault detection and correction in Cacti 0.8.7g. What this means to plugins that leverage our rrdtool_function_* functions is that for graphing and certain other functions, those plugins will require a minor change. To date, the plugins that we know of, are THold, Boost, and Realtime. We have not performed a comprehensive audit off all plugins, if you experience problems you should seek out your Plugins' developers to determine the impact.

The other core change in Cacti 0.8.7g, is Cacti's ability to detect SNMP time-outs in the core SNMP functions. So, if you are using cmd.php or you are using things like MacTrack, that leverage the SNMP API in Cacti, you will have much more capabilities to detect problems in the behaviour of Cacti by simply going to the Cacti log file.

Functional Changes in the PIA

When you go to the Plugin Management page, you will notice a fairly significant change. In this release, we tuned up the Plugin Management interface to make it a bit easier to understand how your plugins are loaded and controlled. There is now the concept of a System plugin and a General plugin. You can also define the load order of your PIA 2.x plugins. This is important in that some plugins require other plugins be loaded first in order to work properly. We still do not have an API to control this. That will be delivered in the next release of Cacti. However, for those of your who have been locked down to having your plugins in PIA 1.x due to the load ordering issue, that barrier will be removed in this release.

Reporting Bugs

It's important that you use the forums to have a discussion with amongst the members of the Cacti Community. However, when you find a bug, you need to make sure that you use the appropriate forum to open and bring those bugs to a close. That forum is the Cacti bug tracker ( http://www.cacti.net/bugs.php ). All the developers use this tool religiously. So, we need you to do that as well.

We understand that people where expecting a release of 0.8.7g yesterday June 7th.

If all looks good over the course of the next 2 weeks, we will be making an official release of Cacti 0.8.7g, Spine 0.8.7g and Plugin Arch 2.8.

Cacti 0.8.7fは使うなとのこと

よく読んだら「Cacti 0.8.7fは使うな」メールが来ていた．
多分こんな感じかと．

• LDAP 認証でのログインで未定義インデックスの警告が発生する (LDAP authentication for login produces a warning about an undefined index)
• (nowはnoじゃないのかな) グラフビューの自動ページ再表示が機能しない (Automatic page refresh on graph views does now function)
• ユーザー管理のグラフ権限で保存ボタンが処理できない (Save button on user management graph permissions does not work)
• プラグイン アーキテクチャをインストールしたとき，グラフ ツリーの削除が処理できない (Deleting a graph tree does not work with Plugin Architecture installed)
• SNMP バイナリーを使用したとき，いくつかの SNMP 取得リクエストに失敗する (If using snmp binaries some snmp get requests will fail)

6月7日に0.8.7gをリリースするのでマテとのこと．

We are currently advising people to not install Cacti 0.8.7f due to the
following issues:

- LDAP authentication for login produces a warning about an undefined
index
- Automatic page refresh on graph views does now function
- Save button on user management graph permissions does not work
- Deleting a graph tree does not work with Plugin Architecture installed
- If using snmp binaries some snmp get requests will fail

If you have already upgraded to 0.8.7f, you can simple move back to 0.8.7e.

Cacti 0.8.7g will be release on June 7th to address these issues.
