• Java Play Mustache NPE Error

  - by zanedev

  We are getting a mustache play error in production (amazon linux EC2 AMI) but not in development (MACs) and we have tried upgrading the jvm, using the jdk instead, and changing from a tomcat deploy model to match our development environments as much as possible but nothing is working. Please any help would be greatly appreciated. We have lots of shared code in java and javascript using mustache and it would be a big deal to rewrite everything if we had to ditch mustache on the java side. 20:48:52,403 ERROR ~ @6al2dd0po Internal Server Error (500) for request GET /mystuff/people Execution exception (In {module:mustache-0.2}/app/play/modules/mustache/MustacheTags.java around line 32) NullPointerException occured : null play.exceptions.JavaExecutionException at play.templates.BaseTemplate.throwException(BaseTemplate.java:90) at play.templates.GroovyTemplate.internalRender(GroovyTemplate.java:257) at play.templates.Template.render(Template.java:26) at play.templates.GroovyTemplate.render(GroovyTemplate.java:187) at play.mvc.results.RenderTemplate.<init>(RenderTemplate.java:24) at play.mvc.Controller.renderTemplate(Controller.java:660) at play.mvc.Controller.renderTemplate(Controller.java:640) at play.mvc.Controller.render(Controller.java:695) at controllers.MyStuff.people(MyStuff.java:183) at play.mvc.ActionInvoker.invokeWithContinuation(ActionInvoker.java:548) at play.mvc.ActionInvoker.invoke(ActionInvoker.java:502) at play.mvc.ActionInvoker.invokeControllerMethod(ActionInvoker.java:478) at play.mvc.ActionInvoker.invokeControllerMethod(ActionInvoker.java:473) at play.mvc.ActionInvoker.invoke(ActionInvoker.java:161) at Invocation.HTTP Request(Play!)

• Multiple Solution Layout for ASP.NET Web Portal?

  - by Jared S

  At work, we've developed a custom ASP.NET Web Portal (That's very similar to iGoogle). We have "Apps" (self-contained, large web forms) and "Modules" (similar to Google Gadgets). Currently, we use a single-solution model. Right now, we have: 3 core projects 60 application projects 80 module projects To reduce copy and pasting between projects, we're going to factor out common functionality (Data Access, Business Logic) into separate projects. I'd also like to introduce Unit Tests, which is going to increase the number of projects even more. We've already reached the point where Visual Studio is choking on the number of projects. We generally only load the 3 core projects and then whatever app's/module's project we're working on. Would a different solution structure help us out? Our number of projects is only going to increase. In general, an app or module only references the 3 core projects. Soon, apps/modules may start referencing the Data Access/Business Logic projects. But in general, apps and modules do not make references between themselves. So to recap, what is the best practice for solution structure when there are MANY projects that use a small number of core projects?

• MEF instance management

  - by Lawrence A. Contreras

  I am working on application that has multiple modules and sub modules. Here's what I need to do: ModuleA has a sub module SubModuleA, SubModuleB, SubModuleC. I want to export ModuleA, SubModuleA, SubModuleB, SubModuleC. ModuleA can have multiple instances. Whenever I import ModuleA inside the sub modules, I want to get the correct instance and also when I import SubModuleA,SubModuleB and SubModuleC inside other classes. How can I manage that scenario using MEF? Do I really need to use MEF. Updated: Here's a quick example: public class School { List<Classroom> classRooms { get; set; } } [Export] public class Classroom { List<Teacher> teachers { get; set; } } public class Teacher { List<Student> students { get; set; } } public class Student { [Import] Classroom classroom { get; set; } } As you can see, I want to export the classroom class because I need to import it in the Student class, let's just say that I really need the classroom class inside the student class. I want to skip the part where we pass the classroom to the teacher and from the teacher we'll pass it to the student. But when I import classroom, I want to have the correct instance where that class room contains the teacher of the student.

• Wordpress paths issue

  - by Martin

  I have set a crawler up in wordpress which grabs stocks data and writes to file which when a user enters a symbol/ticker the variable is read and if it matches the data of a previous crawl for that particular companies data will echo the text file on page, if no data is found the crawler then sets off grabs it and writes to file to save for the next time that symbol is used. The problem im having is that everything works groovey apart from one thing, when the content is written to file it saves it in the WP root and not inside a subfolder of the theme, basicaly this means that root becomes untidy very quickly and also should the theme be used on another site then its not practical as some important info is missing. I have tried bloginfo and absolute both return the same failure. This is the code i am using to write to file, like i say it works apart from writing the file into root. <?php $CompDetails = "http://www.devserverurl.com/mattv1/wp-content/themes/stocks/tools/modules/Stock_Quote/company_details/$Symbol.txt"; if (file_exists($CompDetails)) {} else { include ('crawler_file.php'); $html = file_get_html("http://targeturl.com/research/stocks/snapshot/snapshot.asp?ticker=$Symbol:US"); $es = $html->find('div[class="detailsDataContainerLt"]'); $tickerdetails = ("$es[0]"); $FileHandle2 = fopen($CompDetails, 'w') or die("can't open file"); fwrite($FileHandle2, $tickerdetails); fclose($FileHandle2); } ?> edit below, have also tried this and the same happens as above <?php if (file_exists($_SERVER['DOCUMENT_ROOT'] . "/wp-content/themes/stocks/tools/modules/Stock_Quote/company_details/$Symbol.txt")) {} else { include ('crawler_file.php'); $html = file_get_html("http://targeturl.com/research/stocks/snapshot/snapshot.asp?ticker=$Symbol:US"); $es = $html->find('div[class="detailsDataContainerLt"]'); $tickerdetails = ("$es[0]"); $FileHandle2 = fopen($_SERVER['DOCUMENT_ROOT'] . "/wp-content/themes/stocks/tools/modules/Stock_Quote/company_details/$Symbol.txt", 'w') or die("can't open file"); fwrite($FileHandle2, $tickerdetails); fclose($FileHandle2); } ?>

• is there a signal emiter/consumer engine (like in Django) for .NET (C#)

  - by user118657

  Has .NET (C#) anything like Django's Signals engine? Our business logic become really complicated over few years of adding new features. I'm going to re-architecture it. Currently all features are very coupled that makes regression errors while changing something one one place - some other place may be broken. I really like Django's apps idea where separate applications introduce new functionality and are absolutely separate. Communication between apps is implemented though signals. I wounder if there is something in .NET that allows to divide project business to many separated "apps" (plug-ins, zones, modules, you name it) and make communication using some kind of "signals". For example we have simple order flow. We can add "coupon app" that if exists in the project adds abilities to use discount coupon. We can add "cross sale" module that if exists adds abilities to offer cross-sale products Email notification module that if exists adds abilities to send order email notifications. But in the same time all this modules are "self-contained" means that communication between them is done using emitting signals (ORDER_PROCCESS_START, ORDER_SUCCESS, etcs) and other modules can subscribe to this signals and process them in required way. This architecture is not related to web, all business logic is processed on the server side like without working with HTTP directly. I wonder if it's good architecture from code maintaining and testing point of few, is it possible to do this in .NET? Any drawbacks that I don't realize now?

• "The breakpoint will not currently be hit" error while debugging a mixed mode application (c# and unmanaged c++)

  - by user1678403

  While debugging a mixed mode application in VS2010, the breakpoint set on a line of code contained in an unmanaged c++ dll source file (called from a managed c# wrapper class) shows the infamous "The breakpoint will not currently be hit. No symbols have been loaded for this document" info message when hovering the mouse over the breakpoint on the line in question. The breakpoint itself is a red circle with a yellow info triangle instead of the usual solid red orb. Of course, the breakpoint isn't hit when the debugger is executed. Most answers I've found for this warning indicate the breakpoint hasn't been set properly, or that the expected dll is not being loaded, or that the associated pdb file is not located in the correct location, etc. etc. This is not the problem. The application does load and execute the referenced dll correctly. I've verified that the correct pdb file, with the same file date as its dll, is located in the executable's working directory along with the target dll itself. The debugger simply doesn't load the symbols for the dll, and the dll doesn't show in the Modules list. None of the solutions I've found online work for this problem. The dll doesn't show in the modules list available from 'Debug-Windows-Modules' menu selection... even though it is, in fact, loaded. Breakpoints set in the wrapper class work correctly. Deleting the bin and obj directories, cleaning and rebuilding the solution also doesn't help.

• Need a VM for running a PHP Sandbox

  - by Phani

  I am working on Web application honeypot. It collects PHP files it receives (as part of an RFI attack) and runs them in order to return the result back to the attacker. The aim is to coax the bad guy into going further into his attack. Based on the answers to my SO question, I am looking at using VMs for running the PHP Sandbox. The honeypot itself consists of Python code and will be running in a Linux environment (preferably Ubuntu-like). These are some of the requirements: The VM should be a light weight as possible. We are going to distribute the code around and many people are going to use the VM along with the Python based honeypot. So, the installation and configuration should not be too difficult. The guest system would also be Linux as we are going to distribute the VM image around. It should be possible for the Python code outside to talk to the guest system. It would be passing on the PHP file to the guest system and will get the output result from it. It should be possible to automate the initial configuration of the VM (such as allocation of RAM etc.) I would like to randomize these settings in order to make the sandbox less 'fingerprintable' I have looked at OpenVZ and KVM so far. Are there any other VMs that I might look at? What do you recommend?

• Using bind (named) as a public proxy server

  - by TrentDavis

  We have a Python DNS server that does a bunch of stuff to figure out values it should return for various DNS records. This works nicely, however as it is Python, the performance under high load won't be great. What I would like to do is have a "proxy" bind server sit in front of it to return results to the public internet. This will cache the results (typically 15 minutes, some records are a few seconds), so the load on the Python server will be greatly reduced as it will only see one look up per domain (only about 100 domains) every 15 minutes. The data in these domains changes a lot, so using a master won't work as it will constantly be changing. I have something setup that looked like it would work great (using a forwarder for the zone), and tested it with dig etc, all going great. However when we went to go live with it, things weren't working, and we figured out that named is not setting the "Authoritative" bit (fair enough, it is a forwarder). So my question is, can we tell bind to set the Authoritative bit for forwarded domains? I have looked at all the doco I can find, and can't find anything about doing things this way. Most of the doco about using it as a proxy if for a LAN to the internet. Ideally I would like to use bind as it is there and installed (CentOS 5 servers). But at a pinch we could look at a different name server to do the work if it just can't be done with bind. Thanks.

• PostgreSQL lots of large Arrays and Writes

  - by strife911

  Hi, I am running a python program that spawns 8 threads and as each thread launch its own postmaster process via psycopg2. This is to maximize the use of my CPU-cores (8). Each thread call a series of SQL Functions. Most of these functions go through many thousands of rows each associated to a large FLOAT8[] Array (250-300) values by using unnest() and multiplying each FLOAT8 by an another FLOAT8 associated to each row. This Array approach minimized the size of the Indexes and the Tables. The Function ends with an Insert into another Table of a row of the same form (pk INT4, array FLOAT8[]). Some SQL Functions called by python will Update a row of these kind of Tables (with large Arrays). Now I currently have configured PostgreSQL to use most of the memory for cache (effective_cache_size of 57 GB I think) and only a small amount of it for shared memory (1GB I think). First, I was wondering what the difference between Cache and Shared memory was in regards to PostgreSQL (and my application). What I have noticed is that only about 20-40% of my total CPU processing power is used during the most Read intensive parts of the application (Select unnest(array) etc). So secondly, I was wondering what I could do to improve this so that 100% of the CPU is used. Based on my observations, it does not seem to have anything to do with python or its GIL. Thanks

• emacs, writing custom commands which use term-mode

  - by valya

  Hello, I'm using Emacs and M-x term for a terminal. Since my typical workflow looks like this: edit some code C-x C-o to the terminal buffer (or C-x b term[Enter] or something) press Up key to use the last command press Enter to run it C-x C-o to go back I want to bind all of these (except the first step... maybe) to one command, I believe Emacs is awesome enough to do that :-) So, a command must: go to the buffer with terminal (maybe it shouldn't change any windows at all, maybe it should split the window vertially (if it weren't split already) and use the right sid) run a last command what've been run there go back to the last buffer/part of the screen Thank you! I'm not really used to the Emacs scripting system, and I hope someone will help me and someone else will be able to use the answer to improve his workflow, since I believe this is a pretty common one Examples of commands: python manage.py test python manage.py test stats python solve.py # for project-euler puzzles :-) the first and the second runs over a ssh (in a terminal) sometimes (I like developing with vagrant) I understand that it's easy to bind the first and the third ones, but the second changes too often - I'd just like to "run last command"

• How to start using twill?

  - by brilliant

  How do I start using twill? I have just downloaded it, unpacked it and clicked on the setup .py file in the folder. The black window (terminal) appeared for a moment and vanished. (I do have Python 2.5 installed on my computer - along with SDK from Google App Engine) In the twill documentation section it says: Downloading twill The latest release of twill is twill 0.9, released Thursday, December 27th, 2007; it is available for download at http://darcs.idyll.org/~t/projects/twill-0.9.tar.gz. You can also use Python's easy_install to install or upgrade twill. twill works with Python 2.3 or later. To start using twill, install it and then type twill-sh. At the prompt type: go http://www.slashdot.org/ show showforms showhistory I am not clear from this passage what I am supposed to type (only "twill-sh" or "twill-sh" and all the words under that line) and where (I tried typing it in the command prompt window of my computer - to no avail) Can, anyone, please, help me out here? Thank You in advance.

• Apache2 Segmentation fault with wsgi_module

  - by a coder

  Apache 2.2.3 is running as an existing web server under RHEL 5. Attempting to set up Trac using wsgi_module. RHEL 5 ships with python 2.4, so in order to use the current version of Trac (1.0) I needed to install it with easy_install-2.6. Trac works with the default mod_python, however users strongly encourage not using this module as it is officially dead. Using RHEL's package manager, I downloaded/installed python26-mod_wsgi.so. I backed up the httpd.conf, then made the following additions: LoadModule wsgi_module modules/python26-mod_wsgi.so #...# WSGIScriptAlias /trac /www/virtualhosts/trac/deploy/cgi-bin/trac.wsgi <Directory /www/virtualhosts/trac/deploy/cgi-bin> WSGIApplicationGroup %{GLOBAL} Order deny,allow Allow from all </Directory> Next I moved trac.conf to trac.conf.bak (contains mod_python calls). I tested the configuration using: apachectl configtest Syntax is OK. So I reloaded the server config using: service httpd reload At this time, all virtualhosted sites stopped responding. I restored my backup copy of httpd.conf, reloaded the server config, and the virtualhosted sites are being served again. A quick look at the httpd error_log shows: [Mon Oct 08 10:20:04 2012] [info] mod_wsgi (pid=28282): Initializing Python. [Mon Oct 08 10:20:04 2012] [info] mod_wsgi (pid=28280): Attach interpreter ''.

• Django apache + mod_wsgi with virtualenv

  - by ArgsKwargs

  I have some questions running multiple Django sites on a VPS I have a server that uses openPanel to automatically create VirtualHosts within apache2. My ideal situation is that I would have multiple virtualenvs with different dependencies installed so the python dist-packages directory isn't contaminated for different Django sites. For example: /home/user/virtualenv1 /home/user/virtualenv2 My django applications reside at /var/www, so For example: /var/www/djangosite1 /var/www/djangosite2 Now I've read upon openPanel docs and figured out the best thing todo is create a django.conf file inside the mydomain.com.inc folder, which looks something like: /etc/apache2/openpanel.d/mydomain.com.inc/django.conf DocumentRoot /var/www/djangosite1/project WSGIScriptAlias / /var/www/djangosite1/project/wsgi.py WSGIDaemonProcess mydomain python-path=/home/user/virtualenv1/lib/python2.6/site-packages <Directory /var/www/djangosite1/project> Order allow,deny Allow from all </Directory> Alias /static /var/www/djangosite1/project/static-root Now my problem is that this setup seems unable to find the virtualenv site-packages thus not recognizing any dependencies available in the given virtualenv Also, commenting out this line doesn't seem to break or change a thing: WSGIDaemonProcess mydomain python-path=/home/user/virtualenv1/lib/python2.6/site-packages For example: > service apache2 start ImportError: No module named South When I install South outside the virtualenv everything works

• Faking a Linux environment without chroot

  - by Pascal

  For a university project I want to test a C++11 program on a 32-core machine. Unfortunately the machine has Ubuntu 12.04 with GCC 4.6 installed (we need GCC 4.7 because of some C++11 threading features). In such an environment I would normally run a chroot with a custom linux (say a debootstrap with Ubuntu 12.10). Since we don't get root access on the machine we can't use chroot. So far I have prepared a run-time environment using debootstrap for our code, I compiled it in the debootstrap environemnt. Then copied it onto the server (using rsync). In order to run our C++ code I set the LD_LIBRARY_PATH to export LD_LIBRARY_PATH=~/debootstrap/usr/lib/:~/debootstrap/lib64/:~/debootstrap/usr/lib/x86_64-linux-gnu/:~/debootstrap/lib/x86_64-linux-gnu/:$LD_LIBRARY_PATH and so far our code seems to run. I'm however stuck with our python code. It doesn't seem to be sufficient to set the paths manually. export PYTHONPATH=~/debootstrap/usr/lib/python2.7/dist-packages:~/debootstrap/usr/lib/python2.7:~/debootstrap/usr/lib/python2.7/plat-linux2:~/debootstrap/usr/lib/python2.7/lib-tk:~/debootstrap/usr/lib/python2.7/lib-dynload:~/debootstrap/usr/local/lib/python2.7/dist-packages:~/debootstrap/usr/lib/pymodules/python2.7:~/debootstrap/usr/lib/python2.7/dist-packages/PIL:~/debootstrap/usr/lib/python2.7/dist-packages/gtk-2.0:~/debootstrap/usr/lib/python2.7 Executing our script results in ImportError: No module named _path Is there an easier way to accomplish a "fake"-chroot than just overriding and creating environment variables? Note I need python since we created a custom C++-Python module in order to run our tests. Maybe I should create two questions from this.

• Nagios send mail when server is down

  - by tzulberti

  I am using nagios 3.06 to monitor the servers. When a service is critical, it sends a mail, but when a server is down no mail is sent. Even if all the services go to critical state, no mail is sent. I have the following configuration: define command {     command_name notify-host-by-email     command_line python /etc/nagios3/send_mail.py "[Nagios] $HOSTNAME$" "******** Nagios ****\n\n Host: $HOSTNAME$\n Description: the server is down" } define command{     command_name notify-service-by-email     command_line python /etc/nagios3/send_mail.py "[Nagios] $HOSTNAME$: $SERVICEDESC$ ($NOTIFICATIONTYPE$)" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\nDate/Time: $LONGDATETIME$\nAdditional Info:$SERVICEOUTPUT$" } The python script is a script to sent a mail. It works if I execute it from the command line, but it doesn't sents an email from nagios. What I am doing wrong? UPDATE: The contact data is: define contact{     contact_name root     alias Root     service_notification_period 24x7     host_notification_period 24x7     service_notification_options w,u,c,r     host_notification_options d,r     service_notification_commands notify-service-by-email     host_notification_commands notify-host-by-email     email [email protected] } define contactgroup{     contactgroup_name admins     alias Nagios Administrators     members root }

• Upgrade of Ubuntu 8.10 distribution fails due to missing packages

  - by Tim

  I have a server that I've forgotten to upgrade for ages, which is still running Intrepid (8.10). I'd like to upgrade it to a newer version of the distribution, so that I can get security patches etc. I found some instructions that tell me to install the package update-manager-core. I tried the following: $ sudo apt-get install update-manager-core but this fails since some of the necessary packages can't be found: ... Err http://archive.ubuntu.com intrepid/main python-apt 0.7.7.1ubuntu4 404 Not Found [IP: 91.189.88.40 80] Err http://archive.ubuntu.com intrepid-updates/main update-manager-core 1:0.93.34 404 Not Found [IP: 91.189.88.40 80] Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/p/python-apt/python-apt_0.7.7.1ubuntu4_amd64.deb 404 Not Found [IP: 91.189.88.40 80] Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/u/update-manager/update-manager-core_0.93.34_amd64.deb 404 Not Found [IP: 91.189.88.40 80] ... I know that Intrepid is no longer supported, and so I guess some of the necessary files may no longer be maintained. But this seems rather unhelpful: I can't upgrade because it's too old, and the only way to fix this would be to upgrade it. Is there a way round this? Is something else wrong?

• Nagios send mail when server is down

  - by tzulberti

  I am using nagios 3.06 to monitor the servers. When a service is critical, it sends a mail, but when a server is down no mail is sent. Even if all the services go to critical state, no mail is sent. I have the following configuration: define command {     command_name notify-host-by-email     command_line python /etc/nagios3/send_mail.py "[Nagios] $HOSTNAME$" "******** Nagios ****\n\n Host: $HOSTNAME$\n Description: the server is down" } define command{     command_name notify-service-by-email     command_line python /etc/nagios3/send_mail.py "[Nagios] $HOSTNAME$: $SERVICEDESC$ ($NOTIFICATIONTYPE$)" "***** Nagios *****\n\nNotification Type: $NOTIFICATIONTYPE$\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddress: $HOSTADDRESS$\nState: $SERVICESTATE$\nDate/Time: $LONGDATETIME$\nAdditional Info:$SERVICEOUTPUT$" } The python script is a script to sent a mail. It works if I execute it from the command line, but it doesn't sents an email from nagios. What I am doing wrong? UPDATE: The contact data is: define contact{     contact_name root     alias Root     service_notification_period 24x7     host_notification_period 24x7     service_notification_options w,u,c,r     host_notification_options d,r     service_notification_commands notify-service-by-email     host_notification_commands notify-host-by-email     email [email protected] } define contactgroup{     contactgroup_name admins     alias Nagios Administrators     members root }

• PHP 5.3.1 Undefined Symbol: OnUpdateLong error on Apache Startup

  - by docgnome

  I'm running Ubuntu 8.04 on this server. I had PHP 5.2 installed via the package manager. I removed it to install PHP 5.3.1 by hand. I built the packages like so ./configure --prefix=/opt/php --with-mysql --with-curl=/usr/bin --with-apxs2=/usr/bin/apxs2 make make install This installed PHP 5.3.1 in /opt/php/ $ php -v PHP 5.3.1 (cli) (built: Dec 7 2009 10:51:14) Copyright (c) 1997-2009 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2009 Zend Technologies However, when I try to start Apache I get this. # /etc/init.d/apache2 restart * Restarting web server apache2 apache2: Syntax error on line 185 of /etc/apache2/apache2.conf: Syntax error on line 1 of /etc/apache2/mods-enabled/php5.load: Cannot load /usr/lib/apache2/modules/libphp5.so into server: /usr/lib/apache2/modules/libphp5.so: undefined symbol: OnUpdateLong [fail] Any ideas what's causing this error? All the references I can see have to do with building php5 packages for php4 or the like. PHP4 has never been installed on this machine.

• WWW::Mechanize for Objective C / iPhone?

  - by dan

  Hi, I want to port a python app that uses mechanize for the iPhone. This app needs to login to a webpage and using the site cookie to go to other pages on that site to get some data. With my python app I was using mechanize for automatic cookie management. Is there something similar for Objective C that is portable to the iPhone? Thanks for any help.
