Wordpress 2.5.1 500 错误解决方法

2008年5月1日

随时听人讲有500错误。
今天在楚云blog上重现了。
抓住机会debug。
结果很快出来：
当你第二次用同样的标题并且标题中含有多字节文字时，有很大机会触发wp一个死循环，然后服务器cpu直接到100%，当运行时间超过max_execution_time时候出现500错误。
死循环在这里：wp-include/post.php

<?php
......
if ( 'draft' != $post_status ) {
    $post_name_check = $wpdb->get_var($wpdb->prepare("SELECT post_name FROM $wpdb->posts WHERE post_name = %s AND post_type = %s AND ID != %d AND post_parent = %d LIMIT 1", $post_name, $post_type, $post_ID, $post_parent));

    if ($post_name_check || in_array($post_name, $wp_rewrite->feeds) ) {
        $suffix = 2;
        do {
            $alt_post_name = substr($post_name, 0, 200-(strlen($suffix)+1)). "-$suffix";
            // expected_slashed ($alt_post_name, $post_name, $post_type)
            $post_name_check = $wpdb->get_var($wpdb->prepare("SELECT post_name FROM $wpdb->posts WHERE post_name = '$alt_post_name' AND post_type = '$post_type' AND ID != %d AND post_parent = %d LIMIT 1", $post_ID, $post_parent));
            $suffix++;
        } while ($post_name_check);
        $post_name = $alt_post_name;
    }
}

死循环触发点：wp-include/wp-db.php

<?php
......
/**
 * Prepares a SQL query for safe use, using sprintf() syntax
 */
function prepare($args=NULL) {
    if ( NULL === $args )
    return;
    $args = func_get_args();
    $query = array_shift($args);
    $query = str_replace("'%s'", '%s', $query); // in case someone mistakenly already singlequoted it
    $query = str_replace('"%s"', '%s', $query); // doublequote unquoting
    $query = str_replace('%s', "'%s'", $query); // quote the strings
    array_walk($args, array(&$this, 'escape_by_ref'));
    return @vsprintf($query, $args);
}

post_name 中的的多字节文字被 urlencode 成这样 "%e6%88%91%e6%93%8d%ef%bc%81"，只要 % 后面跟了 bcdeufFosxX 中任意一个（覆盖了大半个中文区域），就造成 vsprintf 函数调用失败，返回 false，而上层的循环一直在等它返回一个非false的值，直到程序死掉。

解决方法很简单：
修改 wp-include/wp-db.php
用下面的代码替换掉之前贴出的代码：

<?php
......
/**
 * Prepares a SQL query for safe use, using sprintf() syntax
 */
function prepare($args=NULL) {
    if ( NULL === $args )
    return;
    $args = func_get_args();
    $query = array_shift($args);
    $query = str_replace("'%s'", '%s', $query); // in case someone mistakenly already singlequoted it
    $query = str_replace('"%s"', '%s', $query); // doublequote unquoting
    $query = str_replace('%s', "'%s'", $query); // quote the strings
    array_walk($args, array(&$this, 'escape_by_ref'));

    // 旧的方法会引起其他问题
    // $query = preg_replace("#(%[0-f]{2})#sie", "urldecode('$1')", $query);
    // $query = @vsprintf($query, $args);
    // $query = preg_replace("#([\x80-\xff])#se", "strtolower(urlencode('$1'))", $query);

    // 新的方法只针对重复标题时的死循环问题
    $reg = "#post_name = '((?:%[0-9a-f]{2})+.+)'#Usi";
    if (preg_match($reg, $query, $match)) {
        $he = $match[1];
        $hd = urldecode($he);
        $query = str_replace($he, $hd, $query);
        $query = @vsprintf($query, $args);
        $query = str_replace($hd, $he, $query);
    } else {
        $query = @vsprintf($query, $args);
    }

    return $query;
}

后来楚云坚持认为wp可以不用修改任何原始代码解决所有问题，所以找到了下面的方法：
下载这个文件：db.tgz 解压后得到 db.php 将它放到 wp-content/ 下。
---------
或许这只是其中一个造成500的原因，下次遇到再说吧。
--------- update --------
补充，此db.php为2.5.1的，后来才知道2.5.1比2.5.0也有更新，不保证其他版本没有意外情况。
--------- update 2008/05/10 --------
发现bug，更新了方法以及db.php下载链接。以前的方法太粗暴，一些其他的查询也被强制转码造成数据错误。
解决方法：重新下载db.php或按照前文代码重新修改wp-db.php。已经出错的数据，可重新编辑保存。已知会引发错误的地方：http://yourwpuri/wp-admin/widgets.php （也就是说你使用了之前的 db 文件后，有设置过 widgets 功能，最好重新设置一遍）

Leopard 编译 universal php5

2007年12月11日
没有评论

因为自带的php没有gd所以要重编
因为服务器用的是x86_64 httpd+php5所以要编 x86_64
因为自带的httpd+php是 universal ，所以要这样做
自带的httpd很好，所以不搞它了
参考:
ppc就不要了

export MACOSX_DEPLOYMENT_TARGET=10.5
export ARCHFLAGS='-arch i386 -arch x86_64'
export CFLAGS='-arch i386 -arch x86_64 -O3 -pipe'
export CXXFLAGS='-arch i386 -arch x86_64 -O3 -pipe'
export LDFLAGS='-arch i386 -arch x86_64 -bind_at_load'

make时候可能出现这样的提示：

gcc-4.0: -E, -S, -save-temps and -M options are not allowed with multiple -arch flags

在 configure 的时候加上 --disable-dependency-tracking

'./configure' \
'--prefix=/usr' \
'--with-config-file-path=/private/etc' \
'--sysconfdir=/private/etc' \
'--with-apxs2=/usr/sbin/apxs' \
'--with-iconv=/usr/local' \
'--with-mhash=/usr/local' \
'--with-gettext=/usr/local' \
'--with-mysql=/usr/local' \
'--with-mysqli=/usr/local/bin/mysql_config' \
'--with-pdo-mysql=/usr/local' \
'--with-openssl=/usr' \
'--with-zlib=/usr' \
'--with-curl=/usr' \
'--with-gd' \
'--with-png-dir=/usr/X11' \
'--with-jpeg-dir=/usr/local' \
'--with-freetype-dir=/usr/X11' \
'--with-xpm-dir=/usr/X11' \
'--enable-gd-native-ttf' \
'--enable-mbstring' \
'--enable-sockets' \

已有的库就不重装了，只需自己安装 gawk, libiconv, mhash, gettext, mysql, jpeg
需要特别注意：系统自带的liviconv有问题，需要自己编一份到/usr/local(小心不要覆盖以前的，否则可能连sh都不能执行了)，php在configure时就算指定了 --with-iconv=/usr/local 它还是首先找到 /usr/include/iconv.h ,而且 --help 里只提到 --with-iconv-dir=，应该使用 --with-iconv=
解决方法：

sh#mv /usr/include/iconv.h /usr/include/iconv.h.bak

iPhone的通讯录以拼音排序

2007年10月6日

在iphone中安装php
将代码保存为py.php
ssh 登陆iphone或者在iphone安装Term-vt100
执行 php py.php 等待重启完成
结束

支持的中文貌似很有限，拼音表的处理看来要自己搞一个了，这个在网上找的。

py.php

再谈 jre / ZendStudio 中文字体问题

2007年1月23日
没有评论

找了若干资料，终于有了结果
原来如此简单：

把 Courier New 的几个字体文件 copy 到 jre/lib/fonts/

cd xxx/jre/lib/fonts
mkfontscale
cp fonts.scale fonts.dir
cd ../
cp fontconfig.properties.src fontconfig.properties
vi fontconfig.properties

修改相关位置：

monospaced.plain.latin-1=-monotype-courier new-medium-r-normal--0-0-0-0-m-0-iso8859-1
monospaced.bold.latin-1=-monotype-courier new-bold-r-normal--0-0-0-0-m-0-iso8859-1
monospaced.italic.latin-1=-monotype-courier new-medium-i-normal--0-0-0-0-m-0-iso8859-1
monospaced.bolditalic.latin-1=-monotype-courier new-bold-i-normal--0-0-0-0-m-0-iso8859-1

最后再 cp 一个你喜欢的中文字体到 xxx/jre/fonts/fallback/
打开 ZDE，设置字体为 monospaced
这下爽了，我顶你个肺！

注意：此方法只在 Ubuntu 下测试通过，另外 Windows 是不适用的，如果是suse或者redhat之类的系统，主意看 xxx/jre/lib 下面的fontconfig.xxxx 文件，与当前系统相关做相应的修改就可以（没试过）

再说关于jre的字体问题

2007年1月22日
没有评论

其实最简单的解决ZendStudio中文问题方法就是：
(ZDE自带了JRE)
Zendxxx/jre/lib/fonts/
目录下面建一个叫 fallback 的目录，然后 ln 或干脆 cp 一个中文字体进去就OK了，以前还去改什么字体配置文件，真傻B了！
同样sun-jre也是一样的，建立 fallback 目录。
这种方法对 jre1.5 一上版本有效，其他版本据说要修改 lib 下面某个 font开头的文件。

另外说一下，jre1.6 对文字的处理看上去好像调用了操作系统的东西，例如平滑效果。

不知道有没有高人能把 ZendStudio 里的文字效果做成和平果一样的，Courier New 的英文，黑体中文，平滑处理。平果唯一让我怀念的就是这个东西，写代码的时候心情高很多。

Ubuntu 6.10 Edgy 下ZendStudio不能运行的问题。

升级完发现系统速度居然比6.06更快！
其他都还不错，只是ZDE不能运行了，出现以下错误信息：

Configuring the installer for this system's environment...

尝试手动链接 /usr/lib/ 下的文件也不行，发现原来这些文件在 /lib/ 下都是存在的，google以后找到问题所在，然后看到 http://192.150.14.120/cfusion/knowledgebase/index.cfm?id=tn_18831 写的好像是叫修改版本号，具体的搞不懂 echo $LD_ASSUME_KERNEL 也是空的，最后还是注释刁解决问题：

修改 ZDE 把第1488行注释掉（可能是其他行）。

1448 #export LD_ASSUME_KERNEL=2.2.5

另外安装文件也有同样的问题，看引用文写了个脚本：

#!/bin/bash
if [ "x$1" == "x" ]
then
echo "usage: $0 filename";
fi
newfile="new_$1";
cat $1 | sed "s/export LD_ASSUME_KERNEL/#xport LD_ASSUME_KERNEL/" > $newfile;
chmod +x $newfile;
echo $newfile;

保存为例如 newglibc

$chmod +x newglibc

以后遇到这种问题直接：

$ ./glibcFix ZendStudio-xxx.bin
new_ZendStudio-xxx.bin
$ ./new_ZendStudio-xxx.bin

就可以运行了

好像写得有点白痴，太无聊了吧，想多写两个字。

一个常见的xml解析错误解决方法

2006年10月9日
没有评论

反正就是莫名其妙的错误，特别是utf-8的页面，出现这种情况的原因大概因为utf-8的编码格式是变长的，规则比较烦，中途少了一个字节或者多了一个字节就容易出现这类问题，后来用ultraedit查看，发现很诡异，都是那种单字节的字符引起的，一些控制码，反正不管怎样，替换掉这些东西就可以了，这些字符本来也不是用来看的。

$xml = preg_replace('#[\x00-\x08\x0e-\x1f\x7f]+#', ", $xml);
