サーバー移転で、Perlがエラー

らら
らら

はじめに

いままでのPerlは後方互換性が取れていて移転しやすかったんですが・・・

最近、ここ数年Perl 5.14でjcodeの対応、そして5.26でエラーが出て、引っ越し作業がPHPみたいになってきて・・・

まぁ　CentOS 6から7、8毎にエラーでる感じですね。

正直・リニューアルしてほしい。

ディストリビューションごとのバージョン

CentOS 9 AlmaLinux


Perl		5.32 remiで
MariaDB		10.5
MySQL		8.0

CentOS 8 実行カレントディレクトリ。連想配列の%の定義・改行コードなど・・・


Perl		5.26

jcode エラー


efined(%hash) is deprecated at ../perllib/jcode.pl line 684.
       (Maybe you should just omit the defined()?)
defined(%hash) is deprecated at ../perllib/jcode.pl line 693.
       (Maybe you should just omit the defined()?)

jcode.plをエディターで開いて。下記の箇所を変更　unless defined %→　if !%


sub z2h_euc {
   local(*s, $n) = @_;
   &init_z2h_euc unless defined %z2h_euc_inited;
   $s =~ s/($re_euc_c|$re_euc_kana)/
   $z2h_euc{$1} ? ($n++, $z2h_euc{$1}) : $1
   /geo;
   $n;
}
sub z2h_sjis {
   local(*s, $n) = @_;
   &init_z2h_sjis unless defined %z2h_sjis_inited;
   $s =~ s/($re_sjis_c)/$z2h_sjis{$1} ? ($n++, $z2h_sjis{$1}) : $1/geo;
   $n;
}

下記に変更


sub z2h_euc {
   local(*s, $n) = @_;
   &init_z2h_euc if !%z2h_euc;
   $s =~ s/($re_euc_c|$re_euc_kana)/$z2h_euc{$1} ? ($n++, $z2h_euc{$1}) : $1/geo;
   $n;
}
sub z2h_sjis {

   &init_z2h_sjis if !%z2h_sjis;
   $s =~ s/($re_sjis_c)/$z2h_sjis{$1} ? ($n++, $z2h_sjis{$1}) : $1/geo;
   $n;
}

Perl 5.26

■@INCから.が削除された。

これは、いままで下記の書き方でもOKだったのが・・・・


require "xxxxx.pl";

下記のようにしないとだめになった...


require "./xxxxx.pl";

require以外もopenなどファイルを指定する場所は、注意が必要

もしくは、修正するファイルの量・修正箇所が多い場合、下記とかでも

ライブラリのみは。


use lib ".";

または。。。


BEGIN { push @INC, "." if $INC[-1] ne "."; }

カレントディレクトリを使用しているソース先頭に・・


#!/usr/bin/perl
BEGIN { push @INC, "." if $INC[-1] ne "."; }

■連想配列%で、下記のバグぽい記述もNGで動作していたものが動作しない


	%XXXX->{'test'}[1]		= "";

下記、が正解・・


	$XXXX{'test'}[1]		= "";

■ソースの改行コード　CR+LFでもエラーにならなかったが、エラーになる。LFに置き換えて正常になる

実行カレントディレクトリ確認してみた

perl 5.16の設定

@INCの最後に.があります。

変更するソースコードが沢山とか・・他社の書いたコードだから触りたくないという感じの方は・・

セキュリティ面で下がってしまいますが・・・


perl -V:usesitecustomize
usesitecustomize='define';


perl -V:sitelib
sitelib='/usr/local/share/perl5';

上記で判明した/usr/local/share/perl5からsitecustomize.plをさがす・・


ls /usr/local/share/perl5

sitecustomize.plがなければ

sitecustomize.plを作成して下記を追加して、パーミッション変更でOKです。下記1行でOKです。


push @INC, "." if $INC[-1] ne ".";

Perl 5.30

■ File::Slurp 9999.23 read_fileでエラー

Perl 5.30 で、:utf8 ハンドルでバイトを読み書きするために sysread(), recv(), syswrite(), send() を使うことはできなくなります。

ライブラリ最新で問題解決

5.30からかなり・・・詳細は下記から

https://perldoc.jp/docs/perl/5.30.0/perldeprecation.pod

こちらは、再度移転の時・・・わすれないで・・・

さいごに

5.16の方もアプデきちんとされてるんですね。。

RHEL Patch95とかRHEL Patch97の辺がネックなんですかね。。5.26は。。

他社が作ったものは・・・・時間がかかるね。。

あと、Movable Typeもperlなので、centos6から7とか8にアップグレードする場合は、旧サイトでMT ver 6.2以降か最終の6.8とかでバージョンアップしたほうがよいです。

MT年間ライセンス費用は掛かりますが・・・
