Caching Modules on PrestaShop

Caching PrestaShop

6 Replies

hello everybody. actually i’m working for a webagency and i used prestashop to develop an ecommerce with over 3700 products and over 250 categories. pretty huge uh?

well prestashop it’s easy to develop and extend, but it’s not so optimized.. so it’s easy to run into slow queries and server freezes with over 1300 visitors per day. So i had to cache some of biggest queries, like categories tree and subcategories, blocks and products. With those expedients i lowered the number of queries from 200 per page to nearly 40 (there are a lot, i know.. but it’s prestashop, not my fault.)
so let’s start with the fixes! 🙂

first of all, let’s define two variable for our caching system, like the directory path of our cached content. open defines.inc.php and declare a variable, like i did

define('_SQL_CACHING_',  true); //set it to true to enable caching!
define('_PS_CACHE_DIR_',  __PS_BASE_URI__.'cache/'); //cache path!

then make that directory and give it write permissions.

then, let’s introduce some cache functions inside the Tools class file.

	static public function setCache($var,$data,$dir='sql/')
	{
		if (!_SQL_CACHING_) return;

		$path=_PS_CACHE_DIR_;

		$dir.=($var%100).'/'.$var.'/';
		$data=serialize($data);

		$path.=$dir;
		@mkdir($path,0777,true);
		@chmod($path,0777);
		$file=$path.$var.'.cache';

		@file_put_contents($file,$data);
		@chmod($file,0777);
	}

	static public function getCache($var,$dir='sql/')
	{
		if (!_SQL_CACHING_) return false;

		$path=_PS_CACHE_DIR_;

		$dir.=($var%100).'/'.$var.'/';
		$path.=$dir;
		$file=$path.$var.'.cache';

		if (file_exists($file))
		{
			$data=@file_get_contents($file);
			return unserialize($data);
		}
		else return false;
	}

	static public function delCache($var,$dir='sql/')
	{
		if (!_SQL_CACHING_) return false;

		if(!function_exists('rmdirr'))
		{
			function rmdirr($dir)
			{
				if (@file_exists($dir))
				{
					if (@is_dir($dir))
					{
						foreach(glob($dir."/*") as $obj)
							@is_dir($obj)? rmdirr($obj) : @unlink($obj);
						@rmdir($dir);
					}
					else @unlink($dir);
				}
			}
		}

		$path=_PS_CACHE_DIR_.$dir.($var%100).'/'.$var.'*';
		foreach(glob($path) as $filename)
			rmdirr($filename);
	}

let’s examine that functions.. we have:

setCache($var,$data,$dir=’sql/’): write cached data to disk
getCache($var,$dir=’sql/’): read cached data from disk
delCache($var,$dir=’sql/’): delete cached data from disk

how to use those function (parameters explaination)

$var: it’s the variable/file-on-disk name. it must be unique or a cached content will replace another one!
$data: it’s the data that we want to cache. it can be anything: simple variable, array, object..
$dir: it’s the subdirectory of cache path. I use it to differentiate caching path of blocks from main pages, for example.

where to use those functions?
well we have exactly three points where to use these functions: modules (on blocks), pages, single objects.

modules: we have to act inside the module files. normally the main file (same name of module’s directory)
pages: we have to act inside the files of prestashop’s root, like product.php or category.php and interact with smarty (the template engine)
objects: we have to act inside the ObjectModel class

On next posts i will show some examples that describes how to apply these kind of cache!

How to install latest nsmiracle.

51 Replies

nsmiracle is apparently stuck at version 1.2.2 published in 11-07-2008 as shown on his official website.

but that’s not true because is still in development and a currently updated version can be retrieved by using subversion (svn).

let’s see how to proceed.

1) install subversion if miss it and litbool too. libtool is an automated tool that create makefile and configures. open terminal and type

sudo apt-get install subversion libtool

2) download the latest version (actually rev 97) from nsmiracle repository

svn co --username nsmiracle-dev-guest --password nsmiracleguest https://telecom.dei.unipd.it:/tlcrepos/nsmiracle-dev/trunk

3) go inside trunk: main is the nsmiracle latest release and inside addon folder there are sandbox, umts, wimax and other supplementary modules
4) copy main folder and paste wherever you want (i put it inside ns-allinone directory). i suggest to rename main folder to something that you can easily remember (“nsmiracle” for example)
5) open terminal and inside nsmiracle directory type in order (configure need your actually paths. i left mine just for example)

$ ./autogen.sh
$ ./configure --with-ns-allinone=/home/lotti/Scrivania/ns/ns-allinone-2.34 --prefix=/home/lotti/Scrivania/ns/ns-allinone-2.34 --disable-static --with-dei80211mr=/home/lotti/Scrivania/ns/ns-allinone-2.34/dei80211mr-1.1.4
$ make
$ make install

6) now you’re ready to use nsmiracle

if you need to use also addons here there is an example

1) copy the wanted addon directory inside nsmiracle directory
2) open a terminal and go to the addon freshly pasted directory
3) type (always use your actual paths!):

$ ./autogen.sh
$ ./configure --with-ns-allinone=/home/lotti/Scrivania/ns/ns-allinone-2.34 --with-nsmiracle=/home/lotti/Scrivania/ns/ns-allinone-2.34/nsmiracle
$ make

that’s all.

run some samples to check if everything works. (some samples are broken – most errors are on loading libraries because of wrong paths)

Install ns-allinone-2.34 on ubuntu karmic koala 9.10 and ubuntu lucid lynx 10.04

13 Replies

i wrote this tutorial because official ns installation problems website actually return a blank useless page. all the credits goes to nsnam.isi.edu people.
the googled cache copy of the page is here.

WARNING: apply point 3-4 only if you noticed the error while installing ns-allinone-2.34 the first time.

 otcl.o: In function `OTclDispatch':
 /home/ns/ns-allinone-2.34/otcl/otcl.c:495: undefined reference to `__stack_chk_fail_local'
 otcl.o: In function `Otcl_Init':

 ld: libotcl.so: hidden symbol `__stack_chk_fail_local' isn't defined
 ld: final link failed: Nonrepresentable section on output
 make: *** [libotcl.so] Error 1

otcl-1.13 has some compatibility issues with latest g++ (>=4.4) but ns-allinone-2.34 need it.

all you have to do to fix issues and make a successfull installation is:

sudo apt-get install build-essential autoconf automake libxmu-dev

1) extract ns-allinone wherever you want. open directory, go to otcl-1.13.

2) open configure file (the one without extension)

3) search for:

    Linux*)
        SHLIB_CFLAGS=&quot;-fpic&quot;
        SHLIB_LD=&quot;ld -shared&quot;
        SHLIB_SUFFIX=&quot;.so&quot;
        DL_LIBS=&quot;-ldl&quot;
        SHLD_FLAGS=&quot;&quot;
        ;;

and replace it with

    Linux*)
        SHLIB_CFLAGS=&quot;-fpic&quot;
        SHLIB_LD=&quot;gcc -shared&quot;
        SHLIB_SUFFIX=&quot;.so&quot;
        DL_LIBS=&quot;-ldl&quot;
        SHLD_FLAGS=&quot;&quot;
        ;;

4) save configure file

5) go back to ns-allinone-2.34 main directory and launch install.

6) remember to add to your .bash file (hided inside your home directory) with path variables. here there are mine for example

# LD_LIBRARY_PATH
OTCL_LIB=/home/lotti/Scrivania/ns/ns-allinone-2.34/otcl-1.13
NS2_LIB=/home/lotti/Scrivania/ns/ns-allinone-2.34/lib
X11_LIB=/usr/X11R6/lib
USR_LOCAL_LIB=/usr/local/lib
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB:$X11_LIB:$USR_LOCAL_LIB

# TCL_LIBRARY
TCL_LIB=/home/lotti/Scrivania/ns/ns-allinone-2.34/tcl8.4.18/library
USR_LIB=/usr/lib
export TCL_LIBRARY=$TCL_LIB:$USR_LIB

# PATH
XGRAPH=/home/lotti/Scrivania/ns/ns-allinone-2.34/bin:/home/lotti/Scrivania/ns/ns-allinone-2.34/tcl8.4.18/unix:/home/lotti/Scrivania/ns/ns-allinone-2.34/tk8.4.18/unix
NS=/home/lotti/Scrivania/ns/ns-allinone-2.34/ns-2.34/
NAM=/home/lotti/Scrivania/ns/ns-allinone-2.34/nam-1.13/
PATH=$PATH:$XGRAPH:$NS:$NAM

7) test it: close actual terminal and open a new one (to reload changed .bash file) and type “ns”. if a % appear, your actually on ns2 console.

Finish!

jquery: igoogle box-set like script

2 Replies

hello world! (sounds familiar..)

lr1 parser is complete! woooah. it takes me 3 weeks of work and now i will have a printed permanent smile on my face for at least 1 month. well i will post source codes, but not for now :).

today i’d like to show you a nice work made with jquery, a powerful javascript library that i discovered two days ago.

This is a tutorial that will show how to make a simple but nice customizable blocks-made interface/homepage, with jquery. the script is based on this other tutorial.

Here it is the demo: http://www.valerioriva.it/jquery/lotti-block.html
how to use the demo: you will see 6 blocks. click on the wrench to enter customization mode, a dialog will appear. click on every boxes’ icon (click and drag to move blocks with 4 arrow cross) and customize your layout. save or restore states/order/everything if you don’t like the customization.

features:

movable blocks
closable blocks
minimizable blocks
save blocks’ state and order into cookies

let’s start with the html template.

build your html layout.. with divs! made 1 or 2 or 3 or how many you need div “columns”. i’ll choose 3. then, you have to put inside each columns some divs that will be acting as boxes with some simply css commands.

here it is my example [remember to include always jquery library, jquery cookie plugin, jquery ui theme script and of course, my script (lotti-block)]
there is also a css example for people that doesn’t know how to make divs act as blocks

download the demo files!

<div id="customize-dialog" title="Reset Layout Page">
<p>Now you can customize your page.<br /> Move boxes from column to another, minimize/close them or get back to default settings by clicking on these buttons:</p>
</div>


<div id="left">
 <div align="center">PLACEHOLDER</div>
 <div id="b1"><h3>Block 1</h3>
 <div>Block 1</div>
 </div>
 <div id="b2"><h3>Block 2</h3>
 <div>Block 2</div>
 </div>
</div>
<div id="center" >
 <div align="center">PLACEHOLDER</div>
 <div id="b3"><h3>Block 3</h3>
 <div>Block 3</div>
 </div>
 <div id="b4"><h3>Block 4</h3>
 <div>Block 4</div>
 </div>
</div>
<div id="right" >
 <div align="center">PLACEHOLDER</div>
 <div id="b5"><h3>Block 5</h3>
 <div>Block 5</div>
 </div>
 <div id="b6"><h3>Block 6</h3>
 <div>Block 6</div>
 </div>
</div>


 </body>
</html>

ok. now let’s examine this page. every column (they have IDs: left, center and right) must have the class identifier “sortable” and each block must have a different ID (in this example from b1 to b6). then placeholder divs (class=”placeholder”) blocks are used only to facilitate boxes drag’n’drop inside each column.
Every box have some special class that are: customizer, movable, minimizable, closable. each of those words adds an ability to the block. There must be at least 1 customizer (and preferably it doesn’t have to be closeable). you can use every combinations of those class identifier.

Then, a box is defined, as you can see, by this code (for example, i took the last block)

<div id="b3"><h3>Block 3</h3>
 <div>Block 3</div>
 </div>

REMEMBER! there must be a tag with class identifier “portlet-header” (i used h3 but it could be a div too) and another tag (preferably a div) with class identifier “portlet-content”

there is a “dialog” div too (it will act as a dialog box) that will appear when the customizer icon is clicked. it contains buttons to save or restore the homepage configuration/style.

now let’s see something about the js code

//configurable variables

jQuery('.customizer').find('.portlet-header').find('.ui-icon-wrench').click(function() { //and add his action
enableCustomization();
});

jQuery('.sortable').sortable({ //instiate columns as sortable to fetch order from cookie
    				handle: '.ui-icon-arrow-4',
    				tolerance: 'pointer',
items: '.movable',
    				connectWith: '.sortable',
    });

 		getCookie(); //read the cookie

jQuery('.sortable').sortable( 'refresh' ) //refresh columns status
 		jQuery('.sortable').sortable('destroy'); //lock columns

});

well, i commented every function, i hope you will understand. if not, go to jQuery documentation or view the linked tutorials on top of this post.
however, inside the cookie the order is save with strings like this: b1,b2;b3,b4;b5,b6 where the ; stands for “end of column” so it is most important to put ids in the correct order inside getCookie e setCookie functions. the blocks’ state is saved like this: b1=1,b2=2,b4=1 where 1 stands for minimized and 2 for closed. no need to save “normal state” because we already have it by default (everytime you load the page, every is on default order/state). that’s all. hope you liked! feel free to ask questions!
