PHP sessions across sub domains

Params:
PHP-5.3, Apache-2.2

Problem:
I need a single session for mysite.com and admin.mysite.com domains. I would login on main domain mysite.com, and will be already authorized on sub domains like admin.mysite.com.

Solution:
In script before session start need too setup this session parameters:
session.cookie_path = "/"
session.cookie_domain = ".mysite.com" - dot at the beginning is important, it specify use same sessions on sub domains

Example:
Example for Zend Framework application.

Define site domain name value:
*** public/index.php ***
...
defined('SITE_DOMAIN_NAME')
|| define('SITE_DOMAIN_NAME', (getenv('SITE_DOMAIN_NAME') ? getenv('SITE_DOMAIN_NAME') : 'mysite.com'));
...
It seems, if server value SITE_DOMAIN_NAME is not defined, craete it. We will use it in config file.

You can define SITE_DOMAIN_NAME in .htaccess file, Anyway he need to be configured on every server separately.

*** public/.htaccess ***
...
SetEnv SITE_DOMAIN_NAME mysite.com
...

Further I set session values in config file
*** application/configs/application.ini ***
[production]
...
local.session.cookie_path = "/"
local.session.cookie_domain = "." SITE_DOMAIN_NAME
...
This line "." SITE_DOMAIN_NAME is equal to ".mysite.com"

And in Bootstrap.php wee initialize session.
*** application/Bootstrap.php ***
...
protected function _initSession()
{
$localCfg = new Zend_Config($this->getOption('local'), true);
Zend_Session::setOptions($localCfg->session->toArray());
Zend_Session::start();
}

Zend Framework, bind subdomains to modules

Params:

Zend Framework 1.11, PHP-5.3, Apache 2.2, local pc with Gentoo on board.

Problem:

I want to bind subdomains to certain module of Zend Framework application.

Example:

http://mysite.com - follow to default module of my app.

http://admin.mysite.com - follow to admin module.

Controllers, actions and params may be various(global variables also):
http://admin.mysite.com/index/index/foo/bar/......

etc.

Solution:

1) Create site with default Zend Framework module structure.

/var/www/mysite.com/

application/

configs/

modules/

admin/

controllers/

views/

default/

......

Bootstrap.php

......

2) Bind DocumentRoot folder of mysite.com, www.mysite.com, admin.mysite.com to the same folder. In my case it's:
/var/www/mysite.com/public

3) In Bootstrap.php file init application router:

protected function _initRouter()

{

$router = Zend_Controller_Front::getInstance()->getRouter();

$hostnameDefaultRoute = new Zend_Controller_Router_Route_Hostname(':module.mysite.com' , array('module' => 'default'));

$router->addRoute('default', $hostnameDefaultRoute->chain(new Zend_Controller_Router_Route(':lang/:controller/:action/*', array('lang' => 'en', 'controller'=>'index', 'action'=>'index'))));

$hostnameDefaultRoute = new Zend_Controller_Router_Route_Hostname('mysite.com' , array('module' => 'default'));

$router->addRoute('www', $hostnameDefaultRoute->chain(new Zend_Controller_Router_Route(':lang/:controller/:action/*', array('lang' => 'ru', 'controller'=>'index', 'action'=>'index'))))

->addRoute('login' , $hostnameDefaultRoute->chain(new Zend_Controller_Router_Route_Static('login', array('controller' => 'user', 'action'=>'login'))));

// routes for admin area

$hostnameAdminRoute = new Zend_Controller_Router_Route_Hostname('admin.mysite.com', array('module' => 'admin'));

$router->addRoute('admin' , $hostnameAdminRoute->chain(new Zend_Controller_Router_Route(':lang/:controller/:action/*', array('lang' => 'en', 'controller'=>'index', 'action'=>'index'))))

->addRoute('settings' , $hostnameAdminRoute->chain(new Zend_Controller_Router_Route_Static('settings', array('controller' => 'config', 'action' => 'list'))));

}

==================================================================

In a result will work this url's:

mysite.com/ -> Module: default, IndexController, indexAction, lang: en

mysite.com/en/index/index -> Module: default, IndexController, indexAction, lang: en

mysite.com/en/index/index/foo/bar -> Module: default, IndexController, indexAction, lang: en , params: foo = bar

mysite.com/login -> Module: default, UserController, loginAction

admin.mysite.com -> Module: admin, indexController, indexAction, lang: en

admin.mysite.com/en/ -> Module: admin, indexController, indexAction, lang: en

admin.mysite.com/settings -> Module: admin, configController, listAction

4) Also you can use route names in view helper URL. In view script:

echo $this->url(array(), 'www') will output 'mysite.com/en/index/index'

echo $this->url(array('foo' => 'bar'), 'www') will output 'mysite.com/en/index/index/foo/bar'

echo $this->url(array(), 'login') will output 'mysite.com/login'

echo $this->url(array('page' => 1), 'admin') will output 'admin.mysite.com/en/index/index/page/1'

echo $this->url(array(), 'settings') will output 'admin.mysite.com/settings'

Also you can specify controllers and actions

echo $this->url(array('controller' => 'post', 'action' => 'list'), 'www') will output 'mysite.com/en/post/list'

echo $this->url(array('action' => 'print', 'id' => 2), 'admin') will output 'admin.mysite.com/en/index/print/id/2'

Magento, change emails count in newsletter queue

Params:
Magento 1.6.0

Problem:
When cron execute newsletters, the count of emails which will be send is limited to 20 per request.

Solution:
Notice: This is bad solution!
Edit script app/code/core/Mage/Adminhtml/controllers/Newsletter/QueueController.php
Find string :
$countOfSubscritions = 20;
and set the value which you need. For me is "8" - limit of my hosting (emails count per request).

Gentoo emerge: "A file is not listed in the Manifest ..."

Params:

Linux moon 2.6.39-gentoo-r3 #4 SMP Wed Aug 31 17:44:51 EEST 2011 i686 AMD Athlon(tm) XP 2000+ AuthenticAMD GNU/Linux

Problem:

When I do emerge <some_package> or upgrade my gentoo, emerge give me bulk of messages like this:

!!! A file is not listed in the Manifest '<package_ebuild>'
also have this warning:
Digest verification failed ...

Solution:

1) Download latest-portage snapshot from some gentoo mirrors:

> cd /

> wget ftp://gentoo.kiev.ua/snapshots/portage-20111214.tar.xz

2) Move /usr/portage directory for backup purposes:
> mkdir /root/temp

> mv /usr/portage /root/temp/

3) Extracting the portage snapshot:

> tar xvjf /portage-20111214.tar.xz -C /usr

> rm /portage-20111214.tar.xz

4) Sync new portage:
> emerge --sync

That's all now you can update the system or .....

I don't know if this is correct solution, but it working for me.

LDOCE5 no sound solution.

Params:
Linux solar 2.6.38-gentoo-r6 #21 SMP Wed Nov 9 21:29:55 EET 2011 x86_64 AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ AuthenticAMD GNU/Linux
You must had installed and configured 'alsa-oss'

Problem:
No sound in LDOCE5 application.

Solution:
Add 'aoss' to exec ldoce5 command.
Desktop link:
Edit desktop file ldoce5.desktop. Add 'aoss' in the command on Exec line
Exec=aoss '/<path_to_ldoce5_install_dir>/ldoce5//ldoce5'

Also you can create command in user '~/.bashrc' file. Add this line in your .bashrc file
alias ldoce5="aoss /<path_to_ldoce5_install_dir>/ldoce5/ldoce5"
And after reboot you can use 'ldoce5' command to execute application with fixed sound.

May be you have "aoss32" instead "aoss", it also working, trying.

PHP sendmail, save mails in local filesystem folder

Params:
OS: Gentoo
Language: PHP 5.3.8

Problem:
Save mails sended from PHP script in local filesystem folder.
View them by KMail

Solution:
Make all changes relative to your distro.
1) Create script fakesendmail.sh

#!/bin/sh
prefix="/home/<my_username>/temp/sendmail/new"
numPath="/home/<my_username>/temp/sendmail" if [ ! -f $numPath/num ]; then
echo "0" > $numPath/num
fi
num=`cat $numPath/num`
num=$(($num + 1))
echo $num > $numPath/num name="$prefix/letter_$num.txt"
while read line
do
echo $line >> $name
done chmod 777 $name

/bin/true

I saved it in folder /home/<my_username>/Applications/

Don't forget set appropriate pathes in script.

2) Make this script executable: console> chmod +x fakesendmail.sh

3) Create folders for mails:

console> mkdir

/home/<my_username>/temp/sendmail/

console> mkdir

/home/<my_username>/temp/sendmail/cur

console> mkdir

/home/<my_username>/temp/sendmail/new

console> mkdir

/home/<my_username>/temp/sendmail/tmp

4) Change folder properties: console> chmod 777 -R

/home/<my_username>/temp/sendmail/

5) Make changes in php.ini file (on gentoo: /etc/php/apache2-php5.3/php.ini)

Change path to sendmail script to our new script:

sendmail_path = /home/<my_username>/Applications/fakesendmail.sh
6) Open KMail and create new incoming account.
Kontact->Settings->Configure KMail->Accounts->Add Account
In opened window choose "Maildir mailbox" and set appropriate folder "

/home/<my_username>/temp/sendmail"

Magento database add table prefix

Problem:
Store setup was without database table prefix.
Now I need to move magento database to existing db with tables from another application.

Parameters:
Magento version 1.6.0

Solution:
Create script "add_db_prefix.php" in your store public catalog. Listing:

<?php
$database_host = "localhost"; // Here database server, ip or domain name
$database_user = "<your_db_user>";
$database_password = "<your_db_user_password>";
$magento_database = "<your_db_name>";
$table_prefix = "mage_"; // Table prefix wich you want!!!

$db = mysql_connect($database_host, $database_user, $database_password);
mysql_select_db($magento_database);
$result = mysql_query("SHOW TABLES") or die('Err');
while (($row = mysql_fetch_array($result)) != false) {
$old_table = $row[0];
if (preg_match('/'.$table_prefix.'/', $old_table)) {
echo "Table $old_table already done<br/>\n";
continue;
}

$new_table = $table_prefix.$old_table;
echo "Renaming $old_table to $new_table<br/>\n";
$query = "RENAME TABLE `$old_table` TO `$new_table`";
mysql_query($query);
}
?>

Do not forget change db conection data in script!
Follow to the url: http://<your_store_domain_name>/add_db_prefix.php
Now all tables in db with new prefix.
And of course you need setup table prefix in your store config file.
Edit config: "app/etc/local.xml"
Find string: "<table_prefix><![CDATA[]]></table_prefix>"
Put there your new table prefix: "<table_prefix><![CDATA[mage_]]></table_prefix>"

Magento Admin Notification bugfix

Magento v.1.6
Trouble:
Every time when I am login to the admin panel see this message:"Reminder: Change Magento`s default phone numbers and callouts before site launch"
It's really damn annoying.

Sollution:
Copy the file app/code/core/Mage/AdminNotification/Model/Resource/Inbox.php
to app/code/local/Mage/AdminNotification/Model/Resource
Create these folders if they does not exists.
And edit this php script.
Line 102. Find:
$select = $adapter->select()
->from($this->getMainTable())
->where('url=?', $item['url']);
Replace it by:$select = $adapter->select()
                ->from($this->getMainTable())
                ->where('url=? OR url IS NULL', $item['url'])
                ->where('title=?', $item['title']);
Delete all your notifications.

Drivers SN9C1* - not for my camera
Kernel configuration by this tutorial http://en.gentoo-wiki.com/wiki/Webcam
But without support of GSPCA drivers.
My driver is "USB Video Class (UVC)" (uvcdriver)
Also enable all v4l and v4l2 support in kernel
And no other devices can't be pluged to the same bus with webcamera (there is some driver bug, I hope developers fix that)
