FreeBSDのportsにSquirrelmailが入るようになってからずっとports版のSquirrelmailを使っていました。でも、php5.4の環境でインストールしようとするとportsが
/usr/ports/mail/squirrelmail# make configure ===> squirrelmail-1.4.22_3 cannot be installed: doesn't work with lang/php5 port (<span style="color: #ff0000;">doesn't support PHP 5.4</span>). *** [configure] Error code 1 Stop in /usr/ports/mail/squirrelmail.
と怒ってインストールさせてくれません。仕方が無いのphp 5.3 (php53-*)のportsを入れてやり過ごしてきました。
最近になって、Squirrelmail本家のサイトを見てみると、
ANNOUNCE: PHP 5.4 & 5.5 Compatibility
May 30, 2013 by Paul Lesniewski
PHP 5.4 and PHP 5.5 compatibility fixes are live in our nightly snapshots, and we strongly encourage those who’d like to help test or those who are having problems with version 1.4.22 to download a snapshot and report any problems.
と出てたのでｐｈｐ 5.4でこのsnapshotはどうなるのか試してみました。
http://snapshots.squirrelmail.org/squirrelmail-20130825_0200-SVN.stable.tar.gz
Squirrelmailのsnapshotをサーバーにダウンロードして、/usr/local/www/squirrelmailに展開します。ports版で使っていた./config/config.phpをそのまま使ってもよかったのですが、今回は新規で設定し直しました。 ./configureで環境に合わせて設定します。

Command >>D Set pre-defined settings for specific IMAP servers
SquirrelMail Configuration : Read: config.php --------------------------------------------------------- While we have been building SquirrelMail, we have discovered some preferences that work better with some servers that don't work so well with others. If you select your IMAP server, this option will set some pre-defined settings for that server. Please note that you will still need to go through and make sure everything is correct. This does not change everything. There are only a few settings that this will change. Please select your IMAP server: bincimap = Binc IMAP server courier = Courier IMAP server cyrus = Cyrus IMAP server dovecot = Dovecot Secure IMAP server exchange = Microsoft Exchange IMAP server hmailserver = hMailServer macosx = Mac OS X Mailserver mercury32 = Mercury/32 uw = University of Washington's IMAP server gmail = IMAP access to Google mail (Gmail) accounts quit = Do not change anything Command >> quit imap_server_type = dovecot default_folder_prefix = trash_folder = Trash sent_folder = Sent draft_folder = Drafts show_prefix_option = false default_sub_of_inbox = true show_contain_subfolders_option = false optional_delimiter = detect delete_folder = false Press enter to continue...
以上の設定で結果的に元々の./config/config.phpと新規との違いは
# diff ./config/config.php-ports ./config/config.php 68c68 < $force_username_lowercase = false; --- > $force_username_lowercase = true; 189a190,193 > $theme[52]['PATH'] = SM_PATH . 'themes/solarized_light.php'; > $theme[52]['NAME'] = 'Solarized Light'; > $theme[53]['PATH'] = SM_PATH . 'themes/solarized_dark.php'; > $theme[53]['NAME'] = 'Solarized Dark'; 220a225 > $browser_rendering_mode = 'quirks';
これだけでした。
httpd.confの設定はこんな感じ。
Alias /webmail "/usr/local/www/squirrelmail"
<Directory /usr/local/www/squirrelmail>
AllowOverride All
Options FollowSymLinks ExecCGI Includes
Allow from All
</Directory>
Apacheを再起動してwebmailとしてアクセスしてみると、
Strict Standards: Non-static method Message::parseStructure() should not be called statically in /usr/local/www/squirrelmail/functions/mime.php on line 36
Strict Standards: Non-static method Message::parseBodyStructure() should not be called statically in /usr/local/www/squirrelmail/class/mime/Message.class.php on line 296
Warning: Cannot modify header information – headers already sent by (output started at /usr/local/www/squirrelmail/functions/mime.php:36) in /usr/local/www/squirrelmail/functions/page_header.php on line 31
こんな感じで新規にメールを開くときにエラー(警告)が出てきて画面が乱れます。調べてみると、php 5.4からより厳格に書式をチェックして警告を出すようになったみたいで、以下のようにphp.iniでエラー表示レベルを変更することでこれらのメッセージを消すことができました。
; - Show all errors except for notices and coding standards warnings ; ;error_reporting = E_ALL & ~E_NOTICE error_reporting = E_ALL & ~E_STRICT ; Print out errors (as a part of the output). For production web sites, ; you're strongly encouraged to turn this feature off, and use error logging
ざっくりですが、日本語で使ってみても大丈夫のようです。以前、php 5.4対応をするという記事で書かれていたhtmlspecialcharsに対する修正内容相当のコードが入っているみたいです。
./functions/strings.php
/**
* Wrapper for PHP's htmlspecialchars() that
* attempts to add the correct character encoding
*
* @param string $string The string to be converted
* @param int $flags A bitmask that controls the behavior of htmlspecialchars()
* (See http://php.net/manual/function.htmlspecialchars.php )
* (OPTIONAL; default ENT_COMPAT)
* @param string $encoding The character encoding to use in the conversion
* (OPTIONAL; default automatic detection)
* @param boolean $double_encode Whether or not to convert entities that are
* already in the string (only supported in
* PHP 5.2.3+) (OPTIONAL; default TRUE)
*
* @return string The converted text
*
*/
function sm_encode_html_special_chars($string, $flags=ENT_COMPAT,
$encoding=NULL, $double_encode=TRUE)
{
if (!$encoding)
{
global $default_charset;
if ($default_charset == 'iso-2022-jp')
$default_charset = 'EUC-JP';
$encoding = $default_charset;
}
if (check_php_version(5, 2, 3))
return htmlspecialchars($string, $flags, $encoding, $double_encode);
return htmlspecialchars($string, $flags, $encoding);
}
