

Cloud Computing and SaaS (Software as a Service) These are two major strategic developments that will disrupt the information systems business by decoupling the Usage from the Infrastructure. ◦

USAGE = Saas (pronounced 'sass') is a model of software deployment whereby a provider licenses an application to customers for use as a service on demand.  



SaaS is pushed by:  

◦

Applications are hosted on the provider web servers Applications are loaded on demand and disabled after use or contract expiration.

Need to use/pay software license on-demand Improve application’s inter-connections by using the same tools among large groups of users

INFRASTRUCTURE = Cloud computing is a way of computing, via the Internet, that broadly shares computer resources instead of using software or storage on a local PC. 



NOTE: confusion may arise because Cloud computing providers also promote a SaaS offer to run on their infrastructure.

Cloud computing is pushed by: 

Need to improve the CADE - Corporate Average Data center Efficiency 

 

waste of energy to power large, numerous, under-used data center (be greener)

Share maintenance costs of data center Scale user infrastructure to what they really need (computing power and time slots)

GUIDELINES For QNAP QPKG system v1 development

SUMMARY

Foreword Guidelines for the QNAP QPKG system v1 Overview Development recommendations

Exercise #1 : Asterisk QPKG – IPBX Exercise #2 : XDove – All-in-one Mail Service



Use SVN for versioning ◦ Repository svn://……. ◦ Use of TRAC (TBD)



Use Bugzilla for bug tracking ◦ (TBD)



Use collaborative environment ◦ To share documents ◦ To get support from QNAP



Use QPKG template ◦ sample-qpkg-hello_qnap



There are several levels of packaging: ◦

Packaging applications as a PHP web applications (eg Joomla). The QPKG provides:   

◦

Packaging applications already existing as IPKG modules (eg Asterisk). The QPKG provides:   

◦

A folder with the binary/libs downloaded from the Deb pkg an installation/remove script to copy/remove the files and recreate the symbolic links to the libs a script to Start/Stop the application An URL link to access the Web server/GUI if any

Packaging an application from a source code exists (eg FreeSwitch). The QPKG provides:     

◦

an installation script for the IPKG a script to Start/Stop the application An URL link to access the Web server/GUI if any

Packaging an already existing Debian x86/ARMEL package (eg Mono). The QPKG provides:    

◦

an installation/remove script to copy/remove the PHP code A folder with the web files an URL link to access the application from the QPKG Interface

A folder with your compiled binaries A folder with the binary/libs downloaded from the Deb pkg an installation/remove script to copy/remove the files and recreate the symbolic links to the libs a script to Start/Stop the application An URL link to access the Web server/GUI if any

BUT most of the time you will have to (eg Plugmedia):     

Use some IPKG to install libs Compile some source code to get the application running Write/modify script for the QPKG installation/removal Write/modify script to start/stop the application Develop a PHP interface to enable the user to configure the application

Help and Documentation ◦

Code files MUST BE documented in English

◦

User help pages shall support Internationalization (selectable languages)

◦

Application user interface (web GUI) shall have help pages/pop-ups to provide additional information to the user (English, Chinese)

◦

Applications Notes for each QPKG must be accessible from QNAP website

◦

User documentation, application examples, troubleshooting sections may be gathered as wiki pages

◦

Also consider to translate the application in Chinese if not available    

Translate the Web GUI Translate the Help pages any Translate the Installer if any Optionally, you can translate (low priority)   



Full testing requires the QPKG to be created



Application testing can be done “in situ” by duplication of the QPKG src-xxx folders

◦ You may install the QPKG manually (see §3)

◦ Copy the relevant src-xxx folders for a specific NAS model under: 

/share/xx0_DATA/.qpkg/

◦ Create the symbolic links and set the permissions ◦ Run the application from this location 

Installation debugging is tricky

◦ Once the QPKG is created copy the QPKG into /share/Public ◦ Start the installation using ./your_qpkg.qpkg (self-extraction) ◦ The QPKG installs on your NAS the same way as if it was uploaded and installed from the QPKG interface ◦ Monitor the installation and check for failure ◦ qinstall_xxx.sh script debugging:     

There is no easy way to debug the installation script If the qpkg installation fails use ./built.sh debug and check the temporary folder: /mnt/HDA_ROOT/update_pkg/tmp You will find the qinstall.sh, qpkg-name.tgz, qpkg.cfg and common.sh Edit and modify the qinstall.sh to fix bug Copy the working version back to your SVN



Recommendations (TBD) ◦ Avoid folder removal (rm –R /xxx/$VAR and VAR is empty due to bug or user entry error) ◦ Log your code execution  into a log file for debugging (using a tee instruction for example)  Report critical errors using the QNAP Admin log system (/sbin/write_log)  Keep log file size under control (tail or rotation files)

◦ To improve coding, use “pair programming” on sensitive pieces of code ◦ Use code review across project teams ◦ Cross projects with your colleagues for beta tests

◦ Suggestion : Agile Software development methodology (e.g. Scrum)  List all tasks into a backlog  Extract a backlog subset which can provide in a fixed 2 weeks timeslot, a functional* product with the selected features (Sprint)  Reiterate the Sprints until the backlog gets empty * Functional means, all selected features for the Spring have been implemented,

tested and validated like in a final product



Minimum testing to be performed on a QPKG for each NAS models (series) before Alpha release ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦



If your QPKG (A) is to be used by an other QPKG (B) (eg. PostgreSQL) ◦ ◦ ◦



Test your QPKG (A) with the QPKG (B) Test that the QPKG (A) removal will not destroy data that belong to QPKG (B) For the time being there is no way to prevent the removal of QPKG (A) if QPKG (B) is still installed

Testing with IPKG modules installation ◦ ◦



Test QPKG installation – qinstall.sh script Test QPKG removal - .uninstall.sh script (and check for residue after removal such as broken symblink ) Test QPKG Enable/Disable - .sh script Test QPKG installation and upgrade Test Web GUI if any Test for security issues if the QPKG needs to support some restrictions (password, account, multiusers,…) Test cased can be user cases and may also be providing in the user’s document Any other tests to ensure the QPKG to meet the requirements

Shall you QPKG use IPKG modules, you must test the correct installation of modules If a pre-installation is enabled (see next slides for ipkg modules installation) check for failure and possible remote ipkg installation from Internet

QPKG shall be released for Production ◦

Ensure to fully passed the Alpha and Beta levels

SUMMARY

Foreword Guidelines for the QNAP QPKG system v1 Overview Development recommendations

Exercise #1 : Asterisk QPKG – IPBX Exercise #2 : XDove – All-in-one Mail Service



Standard QPKG installation procedure 1. Download the QPKG from the QNAP servers 2. Upload the QPKG on the NAS with the NAS Administration web UI 3. Install by clicking the INSTALL button



Manual QPKG installation procedure 1. Copy the QPKG on the NAS (eg /share/Public) 2. Auto-run the QPKG - ./qpkg_name_ver_model.qpkg



Once the installation has been launched, ◦

The QPKG is copied into a temporary folder

◦

The QPKG is self-launched to:

/mnt/HDA_ROOT/update_pkg/tmp

  

Extract the embedded tar archive thanks to the built-in.sh bootstrap script Execute the qinstall_xxx.sh script to proceed with the installation Remove the files from th temporary folder

◦

The qinstall.sh script has several functions to handle the different situations: 

Utils Defines section 

All bash commands used



System Defines section



QPKG Info section

 

Required by the QPKG system Source the common variables defined in config.cfg



Routines to install or check for libs required by the QPKG application

 

Routines to execute during installation The TAR file extraction is handled in the install() routine



Routines to clean-up, remove temp file, etc …



If an update is detected (QPKG already installed) this routine shall receive the code to backup data for example.



Update the application files concerned by the upgrade procedure

post-install() – Add you code here



pre-update() – Add you code here

post-update() – Add you code here



If an update is detected (QPKG already installed) this routine shall receive the code to restore the previously backup data for example. your_routine() 



You may need to add your own routine to keep the script more legible

◦

The qinstall.sh script structure – cont’d: 

_exit() – DO NOT MODIFY



find_base() – DO NOT MODIFY

  

Exit the script and return a message in the NAS log Get the shared folder in QPKG_BASE=[HDx_DATA or MDx_DATA] Set the QPKG_INSTALL_PATH and QPKG_DIR

set_req_permissions() – Add you code here



install() – DO NOT MODIFY UNLESS THERE IS A VERY GOOD REASON

   

Create the symbolic links needed by the appllication Set the permissions on files and folders Proceed with the files copy A folder for each QPKG is created under /share/xx0_DATA/.qpkg (where xx stands for HD in std mode or MD in RAID mode)

The qinstall_xxx.sh script is no longer available after installation. QPKG removal is managed by the .uninstall.sh script.



The .uninstall.sh script (Please, leave the place clean after QPKG removal) ◦ ◦ ◦

The script is stored under the QPKG src-shared folder The .uninstall.sh script is used during QPKG removal operation There is one uninstall.sh script for all NAS type (use model detection if needed)

◦

Keep in mind :  To set the QPKG name in QPKG_NAME variable – there is no easy way to retrieve safely and automatically the name  To remove dead symbolic links that you have create for your application 

Recreating over an existing symblink may cause some issues



DO NOT remove libs and/or IPKG modules you have installed. They may be used now by other QPKG applications



To remove all configuration files, temporary files or folders that you have created for the QPKG applications and which are not located under the QPKG root folder – clean your mess !



DO NOT delete database system that you have installed but only the database/tables that you have created



Be careful while removing users/groups to be sure they are not used by other applications



The . start/stop script qpkg_name.sh and qpkg_name.conts scripts ◦

The qnap_name.sh script is stored under the apps/qpkg_name/src-shared folder

◦

The qnap_name.sh script is used to  Start the application







When the user press the Enable button on the QPKG Administration page



When the NAS reboot if the QPKG has been enabled

Stop the application 

When the user press the Disable button on the QPKG Administration page



When the user press the Remove button on the QPKG Administration page

Restart the application 

◦

Proceed with a Stop and a Start

The qnap_name.sh script does not need to be modified – modifications are placed into the qnap_name.sh script  Specific code is placed into the qnap_name.conf bash file for each NAS version under the src-xxx folders  The qnap_name.conf file is sourced in the qnap_name.sh file to take into account the specific code



You may have to develop a Application interface

◦ ◦

This does NOT concern the Application PHP to be packages (e.g. Joomla PHP or PhpPgAdmin PHP interface) It is related to YOUR PHP development to create an application configuration page for example.

◦

Configuration and variable in the config.php

  ◦

No hard coded paths please (use path variable in config.php) Variables for : params (Ports, URL, IP Add, …) etc.

Recommended folders structure (to be discussed first and used by EVERYONE) ├─ /src-shared │ └─ / (web gui folder) │ ├─ index.php │ ├─ /database │ ├─ /system │ │ ├─ /_cache Smarty cache │ │ ├─ /_compiled Smarty accelerator │ │ ├─ /config configuration files │ │ ├─ /js JQuery, javascript code │ │ ├─ /libraries │ │ │ ├─ /smarty │ │ │ └─ /editors │ │ │ └─ /tiny_mce │ │ ├─ /langs folder for languages and help files │ │ ├─ /logs │ │ ├─ /inc folder for php files │ │ ├─ /themes │ │ └─ /default Default skin themes │ │ ├─ /css folder for CSS sheets │ │ ├─ /images folder for images and thumbnails │ │ ├─ /js javacript used by the default template only │ │ └─ /tpl (or inc) │ ├─ / src-xxx │ └─ /bin binaries not related to the application (eg. compiled bash) and cgi files Required by Smarty Required by TinyMCE



PHP web interface ◦

Has DOCTYPE = DTD XHTML 1.0 Transitional  

◦ ◦ ◦

Has CHARSET = UTF-8 Is W3C compliant – please submit your pages for compliance Has to support Internationalization for different languages   

◦

Get it from QNAP or mimic the v3 admin GUI Share graphics, CSS, Smarty templates between your QPKG devs

Shall you need a skinner please use Smarty ◦ ◦ ◦



Set a default language to English using a configuration variable in your config.ini Have a language drop list to enable the user selection Optional : Use browser language detection to find the language or fallback to English

Has to follow the QNAP graphical charter  



Needed with JQuery DocType experts are welcomed to address this topic then use the same for all QPKG

Default page size is 1024 x 768 px. Pages must be correctly displayed for this resolution and above. Choose one stable version and keep it for all QPKG

Shall you need a RIA (Rich Internet Application) please use JQuery ◦

Do not mods the JQuery (tweek the code) to allow future upgrades



For application that requires a user configuration ◦ ◦ ◦

Use a QSA – Quick Start Assistant (Wizard) and support internationalization 5/6 pages maximum Users are non-technical persons



PHP web interface ◦ ◦



User is seen as Guest (Apache) User cannot issue admin commands using the exec PHP instruction

A workaround exists ◦ ◦ ◦

Call a CGI code (bash) from the PHP using the wget instruction The CGI code is executed with admin privileges Execution may be incredibly slow because:  



To do ◦

Place you cgi files under the right folder:    



wget start to check for IPV6 then fallback to IPV4 after timeout Need to force IPV4 (use a variable to allow easy setup changes)

apps/qpkg-name/src-shared – for ASCII cgi files apps/qpkg-name/src-xxx – for compiled cgi files CHMOD 755 qpkg_name.cgi Create a symbolic link from qpkg_name/bin/ folder to /home/httpd/qpkg_name

For debugging – unitary tests ◦

Enable your CGI to be run from a shell command line 

PHP code ◦ ◦

Bash command as guest $ret = exec(‘’, $output); Bash command as admin $ret = exec(‘/usr/bin/wget "http://127.0.0.1:8080/’, $output); Please see code examples to log the command output for debugging



Basic restricted access control can be implemented

◦ By using .htaccess file ◦ And user from the /mnt/HDA_ROOT/.config/shadow file  Example: AuthName “This Access is Restricted" AuthType Basic AuthUserFile /mnt/HDA_ROOT/.config/shadow AuthGroupFile /dev/null require user admin



Protect the user’s data

◦ Configuration folders must be restricted access  Eg .htaccess with deny all

◦ Sensitive data must be gathered and stored in a protected folder ◦ Protect user’s data against typing errors (confirm deletion/modifications, enable rollback transactions, confirm password change, etc.) ◦ Use poke-yoke to limit user errors or check user entry consistency  All default answers are Yes but one which is inverted must be set to No  Do not display the ‘Continue’ button unless all fields are fill-in

◦ Implement backup/restore procedures for databases and sensitive data (.bak files, archive)



MySQL database system is available on QNAP NAS ◦ Recommanded by QNAP



PostgreSQL database system is available through a QPKG



SQLite is not available but through the IPKG modules



Translated strings must be able to support : ◦ HTML tags to improve the presentation ◦ Foreign characters, Quotes



There are mainly two implementations today ◦ Use of arrays (plugmedia) 

Loaded as any PHP variable $lang = array( 'TRIER_PAR' =>'Trier par', 'ORDRE_TRIS' =>'Ordre de tris‘);

◦ Use of constants (XDove, q-ext, Q-Sims)



 

Need to process the language text file (parser) Strings are gathered into sections (e.g. by pages, common, buttons, etc.)



[common] charset date_format

= iso-8859-15 = d F Y H:i:s

Translation files for the web interface and help ◦ Are 2 different files ◦ Translation of the apps interface may be used with default English help pages ◦ Do not rely on the LOCALE – NAS are seldom set to correct regionalization 

# locale –a C en_US.utf8 POSIX

◦ Q-Ext QPKG can install locales if needed but uis still Beta and for Tech. guys



Ipkg - Itsy Package Management System, ◦ ◦



is a lightweight package management system designed for embedded devices that tries to resemble Debian's dpkg. is used in the Unslung operating system for the Linksys NSLU2 (Optware), in OpenWRT, Openmoko, WebOS, Gumstix, the iPAQ, QNAP NASes, Synology NASes and elsewhere.

In normal operation ◦

IPKG modules are downloaded from the Internet

◦

IPKG modules are NAS model dependant (libs installation)





BUT we might prefer sometimes to install from a local folder   

◦

◦

x86 : arm-x19: arm-x09:

http://ipkg.nslu2-linux.org/feeds/optware/ts509/cross/unstable/ http://ipkg.nslu2-linux.org/feeds/optware/cs08q1armel/cross/unstable/ http://ipkg.nslu2-linux.org/feeds/optware/cs05q1armel/cross/stable/

Install the ipkg modules in the “correct” order to respect module’s dependencies 

◦

to speedup the installation, to avoid the need for an Internet connection to secure the ipkg modules installation (bad Internet connection)

Download and place the ipkg modules into an ipkg folder under your QPKG tree folder   

If you have not installed an ipkg module (a) when the ipkg module (b) is being installed and required the module (a), a download will be performed.

Installation from a local file: 



Ex. # ipkg install coreutils

Ex. # ipkg install coreutils_8.4-1_arm.ipk

Folder structure to use with IPKG pre-installation ◦ ◦ ◦

Store IPKG modules for each model under /apps/qpkg_name/src-xxx/ipkg folders The IPKG module pre-installation is handled in the qinstall_xxx.sh script An example of such implementation is availabe into the PosgreSQL QPKG
