关于PSR-0的实现以及必须从命令行执行哪些命令，我需要采取哪些步骤从Kohana 3.2升级到3.3？
答案 0 :(得分：6)
Unix命令行：
这些是我在Kohana应用程序中实现PSR-0的步骤。
我删除了以下系统/目录：
rm -rf system
在你当前的bootstrap.php中，唯一的变化就是让类以一个大写字母开头，所以最好是保留旧的引导程序，只需在文件顶部更改以下行：
// Load the core Kohana class
require SYSPATH.'classes/Kohana/Core'.EXT;
if (is_file(APPPATH.'classes/Kohana'.EXT))
{
// Application extends the core
require APPPATH.'classes/Kohana'.EXT;
}
else
{
// Load empty core extension
require SYSPATH.'classes/Kohana'.EXT;
}
从新的kohana发行目录中删除bootstrap.php。现在将3.3的所有文件粘贴到旧应用程序中：
cp -R path/to/new/kohana/* .
现在将所有控制器和模型移动到大写目录并删除旧目录：
mv application/classes/controller/* application/classes/Controller
mv application/classes/model/* application/classes/Model
rm -rf application/classes/controller application/classes/model
供应商目录在kohana目录的根目录中有固定的位置。将您的供应商目录从应用程序/供应商（如果有的话）移动到vendor /
mv application/vendor .
编辑数据库配置文件（例如application / config / database.php），all＆＃34; type＆＃34;属性应大写：
return array
(
'default' => array
(
'type' => 'MySQL',
当您使用AUTH orm驱动程序并且已覆盖application / config / auth.php中的配置时，大写驱动程序名称：
return array(
'driver' => 'ORM',
现在是棘手的部分，这些类的所有类名和文件名都应该大写。转到课程目录。
cd application/classes
复制粘贴此命令：
for SRC in `find . -depth`
do DST=`dirname "${SRC}"`/`basename "${SRC}" | sed -e 's/^./\U&/'`;
if [ "${SRC}" != "${DST}" ]
then
[ ! -e "${DST}" ] && mv -T "${SRC}" "${DST}" || echo "${SRC} was not renamed"
fi
done
（来源：http://forum.kohanaframework.org/discussion/comment/73089#Comment_73089）
此命令以递归方式检查所有目录并将文件名大写。转到应用程序目录。
cd ../
现在在模型和控制器（和帮助器）中，大写所有类名。所以Controller_template_parent必须成为Controller_Template_Parent。我有一些非常低效的命令（所以请贡献）。
find ./ -name \*.php -exec sed -i "s/helper_\([a-zA-Z]\+\)/Helper_\u\1/gI" {} \;
find ./ -name \*.php -exec sed -i "s/helper_\([a-zA-Z]\+\)_\([a-zA-Z]\+\)/Helper_\u\1_\u\2/gI" {} \;
find ./ -name \*.php -exec sed -i "s/helper_\([a-zA-Z]\+\)_\([a-zA-Z]\+\)_\([a-zA-Z]\+\)/Helper_\u\1_\u\2_\u\3/gI" {} \;
./开头是所有文件（递归目录），以.php结尾。我添加了一个＆＃34;我＆＃34;在sed命令后面使搜索大小写不敏感。 （源命令：https://askubuntu.com/questions/84007/find-and-replace-text-within-multiple-files）
第一个命令将用Helper_Some_thing_here替换helper_some_thing_here。第二个命令会将helper_some_thing_here转换为Helper_Some_Thing_here等。因此，如果您的类名称中包含超过3个下划线，则可以构建自己的命令。
对于以Model_和Controller _
开头的类，需要做同样的事情find ./ -name \*.php -exec sed -i "s/model_\([a-zA-Z]\+\)/Model_\u\1/gI" {} \;
find ./ -name \*.php -exec sed -i "s/model_\([a-zA-Z]\+\)_\([a-zA-Z]\+\)/Model_\u\1_\u\2/gI" {} \;
find ./ -name \*.php -exec sed -i "s/model_\([a-zA-Z]\+\)_\([a-zA-Z]\+\)_\([a-zA-Z]\+\)/Model_\u\1_\u\2_\u\3/gI" {} \;
find ./ -name \*.php -exec sed -i "s/controller_\([a-zA-Z]\+\)/Controller_\u\1/gI" {} \;
find ./ -name \*.php -exec sed -i "s/controller_\([a-zA-Z]\+\)_\([a-zA-Z]\+\)/Controller_\u\1_\u\2/gI" {} \;
find ./ -name \*.php -exec sed -i "s/controller_\([a-zA-Z]\+\)_\([a-zA-Z]\+\)_\([a-zA-Z]\+\)/Controller_\u\1_\u\2_\u\3/gI" {} \;
现在一些仅使用1个大写字母的类名现在用完整大写字母（Html，Url，Http，UTF8）编写。在整个应用程序中替换它们。
在application / dir中执行此命令：
find ./ -name \*.php -exec sed -i "s/Url::/URL::/gI" {} \;
find ./ -name \*.php -exec sed -i "s/Html::/HTML::/gI" {} \;
find ./ -name \*.php -exec sed -i "s/Http::/HTTP::/gI" {} \;
find ./ -name \*.php -exec sed -i "s/Utf8::/UTF8::/gI" {} \;
当您使用ORM驱动程序时，您的所有Orm :: factory（＆＃39; some_class＆＃39;）应该是大写的并且大写到ORM :: factory（＆＃39; Some_Class＆＃39;）。我使用相同的命令来大写所有ORM类并在工厂中大写类名。
find ./ -name \*.php -exec sed -i "s/orm::factory(\(\"\|'\)\([a-zA-Z_]\+\)\(\"\|'\)\(,[^,]*\)*)/ORM::factory('\u\2'\4)/gI" {} \;
find ./ -name \*.php -exec sed -i "s/orm::factory(\(\"\|'\)\([a-zA-Z]\+\)_\([a-zA-Z]\+\)\(\"\|'\)\(,[^,]*\)*)/ORM::factory('\u\2_\u\3'\5)/gI" {} \;
find ./ -name \*.php -exec sed -i "s/orm::factory(\(\"\|'\)\([a-zA-Z]\+\)_\([a-zA-Z]\+\)_\([a-zA-Z]\+\)\(\"\|'\)\(,[^,]*\)*)/ORM::factory('\u\2_\u\3_\u\4'\6)/gI" {} \;
现在我的模块从3.3开始不再兼容，并非所有模块都升级了。如果你想自己升级它们，你可能需要单独检查它们去每个模块的类目录，大写它的文件和它的类名。您可以使用以前的命令。
对我来说，这是一个升级应用程序时的清单，就像我说的那样，请随时提供帮助，以便更容易升级。

基于Daan的答案，我写了一个PHP脚本，将Kohana v3.2升级到v3.3
它可以在github上找到： https://github.com/Choufourax/upgrade-kohana-3_2-to-3_3
或以下：
#!/usr/bin/php -q
<?php
/*
A PHP SCRIPT TO UPGRADE FROM KOHANA 3.2.X TO KOHANA 3.3.X
------------------------------------------------------
Based on the works of :
=> Daan (http://stackoverflow.com/users/987864/daan)
http://stackoverflow.com/questions/13935621/how-to-upgrade-from-kohana-3-2-to-3-3-implementing-psr-0
=> Alex Cartwright <alexc223@gmail.com>
https://github.com/AlexC/kohana-upgrade-script
This script is designed to do bulk changes to your codebase that can
easily be automated, changes that would otherwise have the potential
to take a very long time for a large project. It does not provide a
fully automated migration, and it is highly recommended that you read
the official Kohana 3.3 upgrade guide before running this script.
http://kohanaframework.org/3.3/guide/kohana/upgrading
------------------------------------------------------
Be smart, be safe :
BACKUP YOUR WEBSITE BEFORE RUNNING THIS SCRIPT
------------------------------------------------------
This script handles :
- Changes in Bootstrap / database config file / auth config file
- PSR-0 support (file/class naming conventions)
- Change the file names
- Change the name of class in all files (including calls, extends...)
- Case sensitive ORM, HTTP, URL, UTF8, HTML classes
- New syntax for Browser cache checking
- New syntax for Redirects (HTTP 300, 301, 302, 303, 307)
- Apply the changes listed above in Modules too
- Moving the vendor folder
This script does not handle :
- HTTP Exceptions
- Custom Error Pages (HTTP 500, 404, 403, 401 etc)
- Query Builder Identifier Escaping
- Route Filters
Things to do :
- improve regex to prevent replacement mistakes between class and functions
HOW TO USE
------------------------------------------------------
This script is to use on your local version of your website
Do not use on your production server (as you will experiment permission issues as your server is not supose to let you modify PHP files dynamically for security reasons)
Once your local site is updated and you test everything, upload files via FTP to your production server.
1/ Backup your site
2/ Download kohana 3.3
3/ Manulay replace the following folders from Kohana 3.3 to the website to upgrade :
- system
- modules/auth
- modules/cache
- modules/codebench
- modules/database
- modules/image
- modules/minion
- modules/orm
- modules/unittest
- modules/userguide
4/ Edit the settings at the begining of the script
5/ Run this file
- if you use a Mac : the best way will be to open the php file with BBedit and chose in the '#!' menu "Run in Terminal"
- you can also open a Terminal, go to the script folder and type ./upgrade-kohana.php
- you can also just run the script from your local webserver http://localhost/website/upgrade-kohana.php but it's not recommended as you may have some permissions problem to modify the PHP files
