Create a multiuser git repository with gitolite

Ivan Villareal — Tue, 01 Nov 2011 22:57:54 +0000

I use git for almost all my developments, is fast, it works locally, and I can even use it as a quick deployment tool, by adding hooks, but when it comes to sharing a repository to other developers, I don’t like the idea of creating a user account in the system for each developer, so the easiest and fastest way to solve this issue for me is using gitolite.

In this post I will describe the steps needed to setup a central repository for multiple users. I’m using Centos 5.5 as server and debian as a workstation

Create a user account in the server and install git

[root@bp ~]# useradd -m git 
[root@bp ~]# passwd git
[root@bp ~]# yum install git

Copy your public key from our workstation to the server

If you don’t know how to setup an ssh passwordless login, take a look here

ivan@scorpion:~$ scp ~/.ssh/id_rsa.pub git@bp.com:~/ivan.pub

Clone gitolite into the server

ivan@scorpion:~$ ssh git@bp
git@bp: ~$ git clone git://github.com/sitaramc/gitolite
git@bp: ~$ cd gitolite
git@bp: ~$ src/gl-system-install
git@bp: ~$ gl-setup ~/ivan.pub

Go to the workstation to manage the git repo

ivan@scorpion:~$ mkdir -p git/bprepo
ivan@scorpion:~$ cd git/bprepo
ivan@scorpion:~$ git clone git@bp:gitolite-admin

At this point we have 2 folders inside gitolite-admin conf/ and keydir/ the first one is used to create new repositories or add users to repositories the second one is for adding each user public key.

Once you have added new repositories and users you need to do a

git push origin master

on each new repo

NFS Mac OSX Lion

Ivan Villareal — Mon, 29 Aug 2011 19:37:57 +0000

I was in the need of sharing files from a mac osx 10.7 and some linux servers, so I tought this would be a simple process just like in linux, but I found some issues that prevented me to mount exported dirs to the mac or setup a nfsd on the mac OS, this is more a reminder to my self about how I was able to perform that.

Case 1 – Mac OSX as NFS server:

this problem with this one is that the syntax of the exports is different from what I know, but after changing some options I was able to export the Users folder on the mac with the following line:

/Users -alldirs -network 192.168.0.0 -mask 255.255.0.0

to mount the above on my linux box I used this:

ivan@orion:~$ sudo mount -t nfs macbox:Users/ivan/ ivanomac

Only problem found was the weird group and user numbers, so that needs to be mapped out, but because I was only to get some files from the mac I didn’t bother doing that.

Case 2 – Linux NFS server Mac OSX client:

This case is because I have a dev vm, and I need to do constant changes from the mac, the linux flavor of the vm is Ubuntu Server 11.04 and to get the nfs server running I did the following:

scorpion ~# apt-get install nfs-kernel-server nfs-common portmap
scorpion ~# echo “/var/www 192.168.0.0/16(rw,no_subtree_check,no_root_squash)” >> /etc/exports
scorpion ~# exportfs -a

and on the mac I ran the following:

[ivan@kunglao:~$sudo mount -t nfs -o resvport,vers=4 scorpion:/var/www scorpion

with the above I was able to view the files on the ubuntu server, however when I mounted the same export on another ubuntu machine I got the uid/gid wrong, to fix that I just ran the idmapd service on the client machine.

orion ~ # service idmapd start
orion ~# mount -t nfs scorpion:/var/www scorpion

Perl script to manage virtual hosts

Ivan Villareal — Wed, 08 Jun 2011 19:54:57 +0000

I did this script a while back, and I’ve been using it on gentoo, ubuntu and centos distros with a few changes, this can be extended to add new functionality, and it may contain bugs, but so far it has worked for me pretty well, I can add/remove virtual hosts very quickly.

To use this script you only need the packages File::Path and Getopt::Long; both of them are already on newer distros, just put the script somewhere I have it in /usr/local/bin and call it with sudo.

ivan@orion:/var/www/vhosts$ sudo vhost-updater.pl --add --domain test.orion

This is the output:

Creating docroot dir: /var/www/vhosts/test.orion/public_html 
Creating log dir: /var/www/vhosts/test.orion/logs 
Site File: /etc/apache2/sites-available/test.orion 
Creating Vhost... 
Adding host test.orion 
Run '/etc/init.d/apache2 reload' to activate new configuration!
Restarting apache 
 * Restarting web server apache2
 ... waiting    ...done.

Once it has finished, point your browser to http://test.orion, and you’re done.

Enjoy!

Dynamic multi form on same page with jQuery and PHP

Ivan Villareal — Tue, 19 Apr 2011 20:13:50 +0000

This is a little demo of a small app that allow us to have several forms displayed on the same page, organized by sections, a static multiform can be easily created by putting the form contents on divs and hiding them, then when the user clicks on a specific section we hide the previous div, and show the new one, we can wrap it up everything inside a big form, and submit that.

The approach I did for having this same functionality allows me to:

Save each section form before editing a new one
Change any form inputs depending on received data
Validate in the front and backend each section

The main disadvantage is that for each section I’ll do an ajax call, to submit and retrieve the form.

The first thing I did was to write the main html layout I did a simple 2 column layout to use the left block as a form navigator and the right block to show the actual form.

 class="left_block_box">
	 class="left_block_title">
		 Form Steps
	>
	 id="edit_step_box">
		 width="100%" cellspacing="0" cellpadding="0" border="0" style="font-size: 11px;" id="stepTable">
		 class="stepSelected">
			 class="formStep">
				 Name
			>
			 class="stepEdit">
				 id="formstep1" class="pointer placeEdit">Edit>
			>
		>
		>
			 class="formStep">
				 Address
			>
			 class="stepEdit">
				 id="formstep2" class="pointer placeEdit">Edit>
			>
		>
		>
			 class="formStep">
				 Interests:
			>
			 class="stepEdit">
				 id="formstep3" class="pointer placeEdit">Edit>
			>
		>
		>
	>
>

I’ve used a table so I can navigate more easily the DOM with jquery, but this can be changed an ul and it will work the same, the next thing I wrote was the other column wrapper the right block which will holde the actual form retrieved from the server.

 class="right_block_box">
	 class="right_block_title" id="formTitle">
		 Form 1
	>
	 class="multiform_part">
		 Aqui va la forma
	>
	 id="form_step_nav_wrap">
		 id="form_step_nav">
			 id="form_step_left">
				 type="button" value="Previous Step" id="prevStepBtn"/>
			>
			 id="form_step_right">
				 type="button" value="Next Step" id="nextStepBtn"/>
				 type="button" value="Preview Data" style="display: none" id="previewBtn"/>
			>
		>
	>
>

Once I had my basic layout I started with the javascript functionality, the first thing was to create a function that allow me to move from one form to another, passing current form values to the calling script and displaying the new form.

function selectStep(step) {
	var thisStep = $(step).children().attr('id');
	//get current form data to be passed later
	var curr = $(".stepSelected").children(':eq(1)').children().attr('id');
	var formData = $("#form_"+curr).serialize();
	//add class to selected step 
	$("#stepTable tr").removeClass('stepSelected');
	$(step).parent().addClass('stepSelected');
	//put name of step that is going to be edited 
	$("#formTitle").text($(".stepSelected :eq(0)").text());
	$(".multiform_part").html("Loading...");
	//send data to php, and draw new form
	$.post('processForm.php', {
		step: thisStep, saveData: curr, formData: formData
	}
	,function(data) {
		//draw new form
		$(".multiform_part").html(data);
	}
	);
}

This was easy, then I just binded a click event to each step

	// handle the edit  link on each step
    $(".stepEdit").each(function(index){
        $(this).click(function(e){
            selectStep(this);
            }
        );
    });

And now I have a functional multiform pane, that gets its form from php, the backend was also ver simple to make:

< ?php
session_start();
$step = $_REQUEST['step'];
$formData = $_REQUEST['formData'];
function save($step, $data) {
	//$_SESSION[$step] = $data;
	$fields = explode('&',$data);
	foreach ($fields as $field) {
		$keyVal = explode('=', $field);
		$key = urldecode($keyVal[0]);
		$val = urldecode($keyVal[1]);
		$_SESSION[$step][$key] = $val;
	}
}
if ($formData) {
	$formStep = $_REQUEST['saveData'];
	save($formStep, $_REQUEST['formData']);
}
if ($step) {
	switch ($step) {
		case 'formstep1':
					$html = <<<FORM
					<form id="form_{$step}" name="form_{$step}">
					<fieldset>
		    <legend>Personal informationlegend>
		    <div class="fm-req">
		      <label for="fm-firstname">First name:label>
		      <input name="fm-firstname" id="fm-firstname" type="text" value="{$_SESSION[$step]['fm-firstname']}"/>

		break;
		case 'formstep2':
					$html = < <<FORM

		    <div class="fm-opt">

		      <input id="fm-state" name="fm-state" type="text" value="{$_SESSION[$step]['fm-state']}"/>
		    div>
		    <div class="fm-req">
		      <label for="fm-zipcode">Zip code:label>
		      <input id="fm-zipcode" name="fm-zipcode" type="text" value="{$_SESSION[$step]['fm-zipcode']}"/>
		    div>
		    fieldset>
 
		FORM;
		echo $html;
		break;
		case 'formstep3':
					$html = < <<FORM
					<form id="form_{$step}" name="form_{$step}">
		<fieldset>
		<legend>Interests legend>
		    <div class="fm-opt">
		      <label for="fm-int1">Interest 1:label>
		      <input id="fm-int1" name="fm-int1" type="text" value="{$_SESSION[$step]['fm-int1']}"/>
		    div>
		    <div class="fm-opt">
		      <label for="fm-int2">Interest 2:label>
		      <input id="fm-int2" name="fm-int2" type="text" value="{$_SESSION[$step]['fm-int2']}"/>
		    div>
		    fieldset>
 
		FORM;
		echo $html;
		break;
		case 'getAllData':
					echo 'Saved Data
';
 
		print_r($_SESSION);
 
		break;
	}
}
?>

Finally I’ve added some css styles to make it “pretty” and add some other js functionality to navigate back and forth.

Script to copy data from MySQL to postgreSQL

This is a perl script I’ve used to move data from mysql 5.1 to postgres 9, this script doesn’t create a schema, it only grabs the data from mysql and try to put it on the same table in postgres.

Use hotkeys for switching between dual monitors

Ivan Villareal — Mon, 21 Mar 2011 18:46:57 +0000

I just got 2 Asus ML228 wide-screen monitors, this is a big update from my previous monitors resolution that were 1280×760, and they were not wide-screen, so it took me a while to get used to these wide screen display, I have them in Full HD via DVI to HDMI connector, I’m using nVidia twinview instead of Xinerama because I can use compiz with twiview and not with Xinerama, the total display I get from both monitors is 3840×1080 pixels (966×272 millimeters), so I have to move my hand a lot to switch between one monitor and the other with the mouse, I also have my netbook on the left because thats were I have my chat and email apps, so to get there from the right screen I have to move even more my hand until I get to the end of the pad.

A friend of mine recommend to use a program to switch between my two monitors with a hotkey, he told me the program he used for windows, I look for it, and I didn’t found a clone that could work in linux, because I was to busy I left that, until the past week, where I just got tired to move from one window to another to check my tests, so I checked again what were my options, and didn’t found nothing that was pretty simple.

I knew that I could leverage the commands plugin from compiz to grab the hotkeys, I just needed a way to move the cursor, so I did a quick search in the aptitude repository

ivan@orion:~$ apt-cache search input move

gave me this:

xdotool - simulate X11 keyboard/mouse input

That looked like the thing I needed, so I’ve installed xdotool and started playing with it, I quickly found that this little tool has a lot of nice choices that can be used for many, many things, so what I did to achieve my goal was the following:

ivan@orion:~$ xdotool --help
Available commands:
  getactivewindow
  getwindowfocus
  getwindowpid
  search
  help

  get_desktop_for_window
ivan@orion:~$ xdotool getmouselocation

and with that my pointer moved to a random position I moved the mouse to the center of left screen the used getmouselocation, I did the same for right screen and with all the parameters I’ve opened my compiz configuration

Decrypting SourceCop php files

Ivan Villareal — Wed, 10 Feb 2010 19:41:46 +0000

Every once in a while, I receive code that is encrypted using one of many php encoder software out there, so when I face this situation and if the project is worth it, I start playing around with the encrypted files to see how the encoding algorithm works, so far I’ve been able to successful decrypt files encoded with Zend, and ioncube, I don’t remember the versions of the encoders but I remember that the latter one took me some time, but I did it.

I must say that decoding files also becomes a personal challenge, it is like a hobby when I have the time to play with it.

Yesterday I received a couple of files encoded with an unknown encoder for me, it didn’t require any php modification or extension install, so I tough that it would be easy to break it, because at some point the code must be evaluated, so after I opened the zip file, I noticed a folder called “scopbin“, that contained only 1 php file named “911006.php“, the two encoded files were including this file so I assumed that this is were the decryption logic had to be.

I was exhausted by a long working day, and when I got this files and saw that they were encrypted I placed them in my laptop for later analysis. This analysis was done while I was waiting for the local news, I didn’t research the encoding, or did anything that give me some pointers, I just started to playing around with the code to see how far could I get.

My objective this time was getting this files decrypted, and not analysing the steps of the algorithm, so with this in mind, this is what I did:

This was the original “911006.php” file:

After a quick review of this file, I saw that it had several functions that had same logic, return an unknow variable or delete the file that this unknown variable had, appart from all this “useless” functions I quickly found what appeared to be the decryption function this was the function named y0666f0acdeed38d4cd9084ade1739498 with this information I headed to check one of the encrypted files, and this is how it looked:

eval(y0666f0acdeed38d4cd9084ade1739498('4EF6454FB298E72B 5', $REXISTHEDOG4FBI));

So what we have here is more obfuscated code, but a simple to understand, we have 2 variables and 3 functions, the variable that has the encrypted code should be the larger one so I'm assuming that is the "$REXISTHEDOG4FBI" variable, the other one apparently isn't used, so what I did at this point was to print the results of the evaluated function which corresponds to the function where the decrypt logic is (deofuscated):

function ($key, $program) {
    $result = '';
    $position = 0;
    $keyLength = strlen($key);
    $decValue = hexdec('&H' . substr($program, 0, 2));
 
    for($i = 2;$i < strlen($program);$i += 2) {
        $decProgram = hexdec(trim(substr($program, $i, 2)));
        $position   = (($position < $keyLength) ? $position + 1 : 1);
        $ascii = $decProgram^ ord(substr($key, $position-1, 1));
 
        if ($ascii <= $decValue) $ascii = 255 + $ascii - $decValue;
        else $ascii = $ascii - $decValue;
 
        $result   = $result . chr($ascii);
        $decValue = $decProgram;
    } 
    return $result;
}

unfortunately printing the result didn't work, so I did a review to check why, and I found that the other 2 functions where the problem, let me explain what happens, first a call is made to

function f0666f0acdeed38d4cd9084ade1739498($x) {
 
    return implode('', file($x));
 
}

this function receives the name of the executing file (test.php in my case), read its content in an array, then glues all lines to create a 1 line string, without any new lines, then this result is passed to the following function:

function g0666f0acdeed38d4cd9084ade1739498($s) {
 
    return (strstr($s, 'echo') == false ? (strstr($s, 'print') == false) ? (strstr($s, 'sprint') == false) ? (strstr($s, 'sprintf') == false) ? false : exit() : exit() : exit() : exit());
 
}

which are a series of nested ternary conditions, looking for the words "echo,print,sprint,sprintf", if any of this words are in the encrypted file, then the script simply exits, that's why I was unable to print the decrypted code after calling the decoding function, so simply avoiding the call to this function will fix the issue and I will get my decrypted code.
However, I didn't want to modify the original encrypted files, so a second approach I took was modifying the decryption function and echoing the output from there, so I've added a couple of lines (15 and 16) to the "y0666f0acdeed38d4cd9084ade1739498" function:

function y0666f0acdeed38d4cd9084ade1739498($x897356954c2cd3d41b221e3f24f99bba, $x276e79316561733d64abdf00f8e8ae48) {

    $x7a86c157ee9713c34fbd7a1ee40f0c5a = hexdec('&H' . substr($x276e79316561733d64abdf00f8e8ae48, 0, 2));

        $xab6389e47b1edcf1a5267d9cfb513ce5 = $xe594cc261a3b25a9c99ec79da9c91ba5 ^ ord(substr($x897356954c2cd3d41b221e3f24f99bba, $x71510c08e23d2083eda280afa650b045-1, 1));
        if ($xab6389e47b1edcf1a5267d9cfb513ce5 <= $x7a86c157ee9713c34fbd7a1ee40f0c5a)$xab6389e47b1edcf1a5267d9cfb513ce5 = 255 + $xab6389e47b1edcf1a5267d9cfb513ce5 - $x7a86c157ee9713c34fbd7a1ee40f0c5a;
        else $xab6389e47b1edcf1a5267d9cfb513ce5 = $xab6389e47b1edcf1a5267d9cfb513ce5 - $x7a86c157ee9713c34fbd7a1ee40f0c5a;
        $x0b43c25ccf2340e23492d4d3141479dc = $x0b43c25ccf2340e23492d4d3141479dc . chr($xab6389e47b1edcf1a5267d9cfb513ce5);
        $x7a86c157ee9713c34fbd7a1ee40f0c5a = $xe594cc261a3b25a9c99ec79da9c91ba5;
    } 
    echo $x0b43c25ccf2340e23492d4d3141479dc;
    die();
    return $x0b43c25ccf2340e23492d4d3141479dc;
}

And voilà, I was able to see the source code.

So in short, just print the output of the decrypt function, and kill the script to get the decrypted code, I don't know if there are any other versions of the "911006.php" file, but I guess that the same logic applies.

Ubuntu 9.10 on an hp mini 110-1125nr

Ivan Villareal — Wed, 27 Jan 2010 00:56:14 +0000

I got this new mini 110, it came with Windows 7 Starter, and after a day of using it I was very frustrated because it was very limiting, for example, I was unable to change my Desktop background, the network management is confusing and frustrating, and it had a lot of crapware, except for the hp games, that some of them are fun.

Anyway, right now I don’t have time to spend getting a new OS on this machine, I just want something that works, I don’t plan using this to work, but I would like to have some of the tools I use into this.

So my options were, trying Ubuntu remix or Windows Xp, after checking that hp had the drivers for XP, I was going to change Windows 7 to Xp, but I was reading how to create a USB boot drive, and it was too much hassle for me. (I’m very lazy for any Microsoft stuff).

My next option was Ubuntu remix, I’m not a big fan of Ubuntu, but I wanted something to just worked out of the box, also this little netbook comes with splashtop, a really nice feature for checking stuff online fast, and I didn’t want to loose this so I really didn’t knew how well this was going to work.

I started downloading Ubuntu 9.10 Karmic yesterday night, just in case, Today after more frustrating things, I decided to give Karmic a try.

I grabbed my usb pendrive, a 1gb kingston traveler, mounted the iso and ran usbinst.exe, it was pretty straightforward, my only advice to you would be to avoid saving space for your documents in the usb, my first try I set this to 30Mb and the boot failed, so I set the do not save feature.

It took about 40 minutes to finish copying the files, after it was done, I restarted the netbook with the pendrive connected, and at the first boot screen I pressed F9 key for booting options, selected the pendrive and that was it.

After testing ubuntu from the pendrive, it ran pretty well and everything but the wifi worked, I did an installation, keeping the windows partition and the hp restore partition, just in case.

The installation was pretty smooth, no issues at all, after the first boot I just installed the broadcom drivers, it was pretty easy with the driver manager in ubuntu, and the wifi was working

Update: My hp mini was stolen by a couple of elderly people, I saw the video , so I’m unable to play more with this, but the time I had this I was very happy with it, it performed well.

File Type Detection in PHP

Ivan Villareal — Fri, 25 Dec 2009 04:47:24 +0000

I’m working on a project where the users can upload files, and I need to know the type of file they are uploading, a simple solution would be to check the extensions of the files, but this has many flaws, so I was looking for a reliable way to detect the type of file, and I found a PECL extension called file info this extension is enabled by default in PHP 5.3, unfortunately I’m runing PHP 5.2.10, and the prod server also has this version.

So what I did to install this on ubuntu 9.10 karmic was the following:

root@mini:/etc/php5/apache2# apt-get install php5-dev libmagic-dev php-pear
....
root@mini:/etc/php5/apache2# pear channel-update pear.php.net
...
root@mini:/etc/php5/apache2# pecl install Fileinfo
....
Build process completed successfully
Installing '/usr/lib/php5/20060613+lfs/fileinfo.so'
install ok: channel://pear.php.net/Fileinfo-1.0.4

and finally I added the extension to php.ini

extension=fileinfo.so

I restarted the apache server, and tested with this

$fileInfo = new finfo(FILEINFO_MIME); 
$mimeType = $fileInfo->buffer(file_get_contents($uploadedFile));

Format a Mysql DateTime Field with Zend_Date

Ivan Villareal — Thu, 10 Dec 2009 19:54:41 +0000

Zend_Date is really a time saver class, I use it in almost every project I work, It handles time_zones, and date formatting pretty easy, leaving me more time to focus on other things.

The files that I need to use Zend_Date as a standalone class are:

Date.php and the Date folder from the Zend distribution package, and this is how I use it:

&lt; ?php
set_include_path('./lib' . PATH_SEPARATOR . get_include_path());
include_once 'Zend/Date.php';
$tugId = isset($_GET['tugId']) ? (int) $_GET['tugId'] : false;
 
function formatDate($date) {
    /**
     * List of supported timezones
     * http://php.net/manual/en/timezones.php
     */
    if ($date) {
        $fmtDate = new Zend_Date($date, Zend_Date::ISO_8601);
        $fmtDate-&gt;setTimezone('America/Los_Angeles');
        return $fmtDate-&gt;toString(Zend_Date::DATETIME);
    } else {
        return '';
    }
}
 
if (is_int($tugId)) {
 $sql = 'SELECT modified_date FROM tuggler WHERE tug_id = ' . $tugId;
 $result = $db-&gt;fetchAssoc($sql);
 $response = 'Last Record Update: '.formatDate($row['modified_date']) .'';
} else {
 $response "nothing to return";
}
 
echo $response;

The response from the above would be Jul 9, 2009 11:41:20 AM but I can easily change it using one of the predefined constants, or I can make my own format.
