by Michal Čihař 21 Mar '13

21 Mar '13

Hi all as Google has started to accept organization applications, I've updated our page on wiki to match this year's questions: https://wiki.phpmyadmin.net/pma/GSoC_2013_Mentoring_Organization_Application I've used past applications and answered some new questions, but help is definitely welcome :-). PS: Dieter, I need your username there (shown as link_id once you login to the GSoC site). -- Michal Čihař | http://cihar.com | http://blog.cihar.com

[Phpmyadmin-devel] Blowfish implementation might be broken
by Michael Hamann 21 Mar '13

21 Mar '13

Hi, I'm part of the developer team of DokuWiki and we are using the same Blowfish implementation in DokuWiki that you are using in PHPMyAdmin so I think you might be interested in what I found out about this Blowfish implementation. I was alerted that something might be wrong in the Blowfish implementation when a user complained that he couldn't decrypt a text that was encrypted on another system. I found that the ciphertext depends on the system (even if both systems are 64 bit systems). I dug a bit deeper into the code and added debug output. After some tests I found that the problem is that the algorithm is adding large integers. The expected result is an integer overflow, however PHP gives a float as result. This float is then used in a binary XOR with an int, I think this results in a cast back to int, but as it is explained in the PHP documentation for floats beyond the integer range this cast is undefined as the float doesn't have enough precision. This loss of precision happens in the calculation of the S-boxes which means that these S-boxes are most probably less random than they should be. I think the security of the algorithm might be flawed because of this but I'm not sure. However at least one thing is clear: this is not Blowfish. Another thing I found strange is that the key setup routine is called after every chunk. I couldn't find any documentation which suggests this as algorithm, what I found is that the p and s-boxes remain the same during the encryption of multiple blocks. We don't plan to fix the implementation, instead we deprecated it and want to replace it after the current release, http://phpseclib.sourceforge.net/ (AES) is a possible candidate. I assume that regardless which library we choose the ciphertext will be different so it doesn't matter if we also switch the block cipher. Regards, Michael Hamann

Hello Everyone, I am Viraj, a fourth year Computer Science student studying here in Manipal in India. I was going through the wiki page for GSOC 2013 idea list.I liked the idea of Automated Testing . I have developed the college website using Php and also done my internship with a start-up company Babajob Services Pvt. Ltd. in India where I had use selenium to write all the tests including Functional Tests, Unit Tests, Integration Tests.So I feel that this is a right fit for me and would love to work on this project. -- Regards Viraj Sinha Dept of Comp Sc MIT,Manipal

Michael Cihar wrote: >Anyway this really does not look like project for whole summer, try proposing something bigger or use some of our ideas. Well that was the first idea. The second one is to develop a Web App based on FireFox OS, as the apps can be run on any system who has FireFox installed on it(even on Android). So the one I would like to develop will have following features: 1. Multiple PMA instances e.g. one of xyz.com another of abc.com. 2. A local cache and Saving queries locally so if someone want to retrieve something later(even without internet he/she can). 3. No need of css and js to be send through request as the app will have them locally. 4. A sweet UI that give a real touch of pma. 5. The app will be a packaged App, so we will be able to trigger an update when we want to do so. It will be truly an Ajax based app, so we need to port new php codes with the next version to make it working but we will be having a support for later versions too. For those who are not familiar with FireFox OS, its a Linux based OS working on b2g(Boot to Gecko) project of mozilla. The app only require FireFox 16 or newer to work. The new upcoming market for mobiles is all set by Mozilla. The apps have their own icon, there dedicated folder and prefs. Regards Dron Rathore

[Phpmyadmin-devel] Gsoc 2013
by Dron Rathore 07 Mar '13

07 Mar '13

Hi all, I am back from my mozilla drive and just going to stick back to pma. I got this idea for Gsoc: Refactorig the Front End Deliverables, Currently we are serving the Js+Css in sprited mode but on the other hand we are not able to Cut down the Bandwidth usage of our users I.e. We can have them served with Cache headers. Also the current scheme is somepage.php?files[]=file1&file2&....[...] As per the web standards any url with query string is never cached. So I would like to turn this into something like this in individual rendering: somefolder/file1 somefolder/file2 Now we will be keeping a gz on server side so that we won't have to gzip the files every time. The files will the served with a cache header so we will be responding back only if the header value IF-MODIFIED-SINCE and will check that with timestamp of the file, in case its smaller then we will gz again else we will just say 301 Not Modified. This will save a lot bandwidth usage and a php5 memory Lekage bug. Regards Dron Rathore 3rd Yr. Computer Engg. Jaipur National University, Jaipur, India

[Phpmyadmin-devel] Abou the GSOC 2013
by Andun Sameera 02 Mar '13

02 Mar '13

Hi All, I am a final year undergraduate who is willing to participate in GSOC 2013. Because of my earlier experience and future interests, it will great if I can do a project in phpMyAdmin. So read the ideas wiki provided by you. I am specially interested in these ideas, Refactoring: Designer/schema integration Refactoring: SQL executor, Column's structure manipulation Refactoring: Server view Can you provide me further steps to continue to work in these ideas? Also If I talk about myself a bit, I had the chance to complete my software engineering internship at WSO2 Lanka Pvt Ltd(www.wso2.com), which is a leading middle-ware solutions development company. Since they are using lot of open source projects, had many chances to get a good exposure to the projects and there code-bases. Also I have did lot of projects in developing those FOSS products. You can find more about those from my LinkedIn profile - lk.linkedin.com/pub/andun-s-l-gunawardana/34/646/703/ or from my blog http://www.insightforfuture.blogspot.com/ Specially I want highlight the project Streaming XPath Parser for WSO2 ESB (http://wso2.org/library/articles/2013/01/streaming-xpath-parser-wso2-esb) which mainly built on top of AXIOM and Data Streams. This implementation provides a high performance XPath parser to the ESB. Also the project of Entitlement Servlet Filter implementation for WSO2 Application Server. http://wso2.org/library/tutorials/2012/12/providing-xacml-fine-grained-auth… So I think the above highlighted experiences makes me a good candidate to do a project in GSOC. Thanks & Regards Andun S.L. Gunawardana Undergraduate Department of Computer Science And Engineering University of Moratuwa, Sri Lanka
