  • Python unittest with expensive setup

    - by Staale
    My test file is basically: class Test(unittest.TestCase): def testOk(): pass if __name__ == "__main__": expensiveSetup() try: unittest.main() finally: cleanUp() However, I do wish to run my test through Netbeans testing tools, and to do that I need unittests that don't rely on an environment setup done in main. Looking at http://stackoverflow.com/questions/402483/caching-result-of-setup-using-python-unittest - it recommends using Nose. However, I don't think Netbeans supports this. I didn't find any information indicating that it does. Additionally, I am the only one here actually writing tests, so I don't want to introduce additional dependencies for the other 2 developers unless they are needed. How can I do the setup and cleanup once for all the tests in my TestSuite? The expensive setup here is creating some files with dummy data, as well as setting up and tearing down a simple xml-rpc server. I also have 2 test classes, one testing locally and one testing all methods over xml-rpc.

  • Physical Cores vs Virtual Cores in Parallelism

    - by Code Curiosity
    When it comes to virtualization, I have been deliberating on the relationship between the physical cores and the virtual cores, especially in how it effects applications employing parallelism. For example, in a VM scenario, if there are less physical cores than there are virtual cores, if that's possible, what's the effect or limits placed on the application's parallel processing? I'm asking, because in my environment, it's not disclosed as to what the physical architecture is. Is there still much advantage to parallelizing if the application lives on a dual core VM hosted on a single core physical machine?

  • Scala Eclipse IDE suddenly ignoring breakpoints

    - by malsmith
    I've been using Scala 2.8RC1 and Scala Eclipse plugin for 2.8 RC1 happily for a few days. However, last night after adding a couple jar files to my environment (apache http client jars) the debugger just stopped stopping at breakpoints in scala code. Java code stops fine at breakpoints. I tried creating a new mimimal scala app breakpoints don't stop. I've tried switching to sun-jre-1.6.0.20 from the openjdk-1.6.18 I had been using. I've switched to the scala 2.8 nightly and also eclipse plugin for scala nightly builds. No luck. I would greatly appreciate ideas for fixes. Rather frustrating as the initial experience with 2.8 was really great.

  • Is this a possible way to get Drupal AD SSO?

    - by JollyRogers
    I'm currently building a Drupal website in an Active Directory environment. One of the site's requirements is Single Sign On, which to date seems to be impossible because there is no Kerberos SPNEGO/GSSAPI auth module for drupal. I've come up with an idea on how SSO could be attempted on IIS. Since IIS has the option to require Kerberos authentication, we can let IIS handle authentication and use the AUTH_USER server variable to pass the authorized user name to the an 'improved' LDAP_auth module. The LDAP_auth module would then check the user name (but not password since it doesn't know or need to know the password) against LDAP to get the user's roles. (AD groups) Does anyone know if this is possible? If so, does anyone have any ideas on how to implement this?

  • Error 500 on template.render() with jinja2

    - by Asperitas
    I am working on playing with some Python to create a webapp. At first I put the HTML in a string, using %s to fill certain elements. That all worked perfectly. Now I want to put the HTML in a template, so I followed this tutorial. My code looks like this (I deleted irrelevant code for this error): import codecs import cgi import os import jinja2 jinja_environment = jinja2.Environment(loader=jinja2.FileSystemLoader(os.path.join(os.path.dirname(__file__)))) class Rot13Handler(webapp2.RequestHandler): def get(self): template = jinja_environment.get_template('rot13.html') self.response.out.write(template.render({'text': ''})) When I replace just template.render({'text': ''}) a random string, the program works fine. I did add the latest jinja2 library to my app.yaml, and naturally my rot13.html does exist with the {{ text }} added. So could anyone please help me in the right direction? I don't know why it's going wrong.

  • What files to be included under VSS 6.0

    - by kheat
    For our .net 3.5 web project, what are the files which needs to be included under VSS 6.0? We have a distributed team of three vendors working on separate modules of our .net portal and all of them maintain their own setup and during release they send across the final build. No surprises that this has caused much headache and we have decided that we will keep this environment under our control and checkout the files when required. This is a multi-part questionnaire and to clear some basics first, we would like to know which are the important files to be kept under VSS6.0. Yes we know VSS 6.0 is outdated but we are playing a catchup game and till we move either to TFS or Subversion( atleast six months down the line) we need a VSS strategy. TIA

  • Scrapy + Eclipse PyDev : how to setup the debugger?

    - by AsTeR
    I've successfully setup Eclipse with my Scrapy project. I did it by setting a new Run/Debug configuration : Whose main module links to Scrapy /usr/local/bin/scrapy for me (I've found suggestion to use cmdline.py but that failed on my computer (OSX Lion & scrapy installed through easy_install) Defining the arguments to send "crawl ny" in my case as I would if I used the Scrapy command line Setting the correct working directory (${workspace_loc:My Project/src} in my case) Eclipse can successfully launch my project, but I've no debbuger. I'm missing my breakpoints and variable inspection, does anyone know how to setup the debbugger with this environment ?

  • Why is GXHC_gx_session_id appended to URLs?

    - by Nariman
    Based on my limited understanding of this parameter [1] it seems to be used in representing cookieless session IDs in java applications... but strangely, we're now noticing that a 3-year-old .NET stack is now appearing in Bing SERPs with GXHC_gx_session_id appended to the domain - and we're not alone: http://www.bing.com/search?q=GXHC_gx_session_id http://www.google.ca/#hl=en&q=GXHC_gx_session_id When comparing Google SERPs to Bing SERPs there are some inconsistencies in whether a particular site carries this parameter - is it then a bing-specific issue only? What else could cause this parameter to be appended to indexed URLs if the target environment (anything behind the load balancers) isn't running java?

  • Using netbeans as IDE for Python

    - by morpheous
    I am about to embark on learning Python (largely for the purposes of using it as scripting glue between my applications). I use Netbeans (6.8) for both my C++ and PHP development work. Ideally, I would like to use the same IDE for Python - and there is a Python plugin for Netbeans (admittedly, its still in Beta). Does anyone have any experience using Python with Netbeans? Shall I use Netbeans (for the reasons stated above - i.e. already familiar environment), or is there a [GOOD] reason why I should use a different IDE?

  • How to set tab stops after whitespaces in latex?

    - by humble coffee
    I'm trying to set tab stops in latex in the tabbing environment. My problem is that I want to set a tab stop after a number of whitespaces. The problem is that latex of course ignores multiple whitespaces, and it seems to only support setting tab stops after actual text. I'm trying to create something like this: A -> B CD -> A The problem is that the extra space after the 'A' is ignored for the purposes of setting the tab stop.

  • Can I change the datsource of report model at runtime

    - by Manab De
    I've some adhoc reports developed on some report models which are published on Report Server (we're using SSRS 2008). Everything is running well. Now in our production environment we've near about forty (40) customers who have their own database (each have the same table structures and other database objects). Now the challenge is whenever a customer will log into the report server using windows authentication and trying to view those reports we need to get the SQL data from the proper database only. Reports are designed using the report model and each model has a valid data source which is connected to particular database. We can create forty separate data sources each will be connected to specific database. My question is, is there any way through which we can change the report model data source name dynamically or during runtime based on the customer name so that during execution of the report, SSRS would fetch the data from the correct database but not from any other database. Please help me.

  • How can I detect endianness on a system where all primitive integer sizes are the same?

    - by Joe Wreschnig
    (This question came out of explaining the details of CHAR_BIT, sizeof, and endianness to someone yesterday. It's entirely hypothetical.) Let's say I'm on a platform where CHAR_BIT is 32, so sizeof(char) == sizeof(short) == sizeof(int) == sizeof(long). I believe this is still a standards-conformant environment. The usual way to detect endianness at runtime (because there is no reliable way to do it at compile time) is to make a union { int i, char c[sizeof(int)] } x; x.i = 1 and see whether x.c[0] or x.c[sizeof(int)-1] got set. But that doesn't work on this platform, as I end up with a char[1]. Is there a way to detect whether such a platform is big-endian or little-endian, at runtime? Obviously it doesn't matter inside this hypothetical system, but one can imagine it is writing to a file, or some kind of memory-mapped area, which another machine reads and reconstructs it according to its (saner) memory model.

  • Automatically update audit information on Entity

    - by Nix
    I have an entity model that has audit information on every table (50+ tables) CreateDate CreateUser UpdateDate UpdateUser Currently we are programatically updating audit information. Ex: if(changed){ entity.UpdatedOn = DateTime.Now; entity.UpdatedBy = Environment.UserName; context.SaveChanges(); } But I am looking for a more automated solution. During save changes, if an entity is created/updated I would like to automatically update these fields before sending them to the database for storage. Any suggestion on how i could do this? Let me know if any more information is needed.

  • GEM Version Requirements Depreciated

    - by Kevin Sylvestre
    When creating a new Rails project using: rails sample Then creating a model using: script/generate model person first_name:string last_name:string Everything is fine. However, if I add any gems to my environment.rb: config.gem "authlogic" And run the same generator, I get the following: /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/rails/gem_dependency.rb:119:Warning: Gem::Dependency#version_requirements is deprecated and will be removed on or after August 2010. The warning just recently appeared (I think), but I would like to fix it if possible. Any hints or similar experiences? Thanks.

  • py2app generates .app with no errors but .app crashes and quits unexpectedly

    - by user3705730
    I am trying to use py2app and it generates .app with no errors but .app crashes and quits unexpectedly. I am trying to do this in virtualenv so I am not sure if that is an issue with all the paths. It works on my computer when all the virtual environments exist but as soon as I close them down, the .app no longer works. The virtual environment I am using has python 2.7.5 Here is my setup.py: """ This is a setup.py script generated by py2applet Usage: python setup.py py2app """ from setuptools import setup APP = ['myApp.py'] DATA_FILES = [] OPTIONS = {'argv_emulation': True, 'packages': ['pulp']} setup( app=APP, data_files=DATA_FILES, options={'py2app': OPTIONS}, setup_requires=['py2app'], )

  • How can I do these operations in C?

    - by Juan Antonio
    Hello, I'm converting some assembly code to C to be able to use it with the current compiler environment I have to work with. I've reached 2 operations I don't know how to translate to C. Anyone know how to do it? In both, offset is an unsigned 32-bit integer and shift is a signed integer value. C_FLAG is a bool. OP1: __asm { __asm mov ecx, shift __asm ror offset, cl } OP2: __asm { __asm bt dword ptr C_FLAG, 0 __asm rcr offset, 1 } Thank you very much for your expertise. P.S.: I'm not the original developer, nor I have seen many x86 assembly code...

  • TextBox loses text when InvokeRequired == false

    - by Tom
    This is modified code I found on this site. When appending text to a TextBox and InvoveRequired is false the text will display in the box but the next time the function is called and InvokeRequired is true the text string placed by the first call is lost (""). Multiple calls when InvokeRequired is true work as expected. comBox is a type TextBox with multline = true. Any help would be appreciated. public void LogComText(string comText, bool newline) { if (comBox.InvokeRequired) { comBox.BeginInvoke(new Action(delegate { LogComText(comText, newline); })); return; } comBox.AppendText(comText); if (newline) comBox.AppendText(Environment.NewLine); }

  • Understanding CGI and SQL security from the ground up

    - by Steve
    This question is for learning purposes. Suppose I am writing a simple SQL admin console using CGI and Python. At http://something.com/admin, this admin console should allow me to modify a SQL database (i.e., create and modify tables, and create and modify records) using an ordinary form. In the least secure case, anybody can access http://something.com/admin and modify the database. You can password protect http://something.com/admin. But once you start using the admin console, information is still transmitted in plain text. So then you use HTTPS to secure the transmitted data. Questions: To describe to a learner, how would you incrementally add security to the least secure environment in order to make it most secure? How would you modify/augment my three (possibly erroneous) steps above? What basic tools in Python make your steps possible? Optional: Now that I understand the process, how do sophisticated libraries and frameworks inherently achieve this level of security?

  • Port a Rails App from Windows to Mac

    - by Ryan Max
    Hello I've been a Rails developer on Windows for quite some time now, but I recently completed my biggest project yet (it's quite extensive, took me over a year to build) but I am having trouble deploying it. The combination of it's size, complexity and a windows environment is making it needlessly complex to deploy. I am thinking about getting an old mac mini and using it just for rails development. Is there any way I can port my app to this mac, without having to start over? I can't find any resources on the internets about this.

  • Processing large recordsets in Rails

    - by japancheese
    Hello, I'm trying to perform a daily operation on a larger than normal dataset (2m+ records). However, Rails seems to take a very long time performing operations on such a dataset. Operations like Dataset.all.each do |data| ... end take a very long time to complete (I assume this is because it can't fit all the items into memory at once, right?). Does anyone have any strategies on how I could handle this situation? I know SQL would probably speed up the process, but I'm looking to use the Rails environment as I can do many more complicated things to the data than I can with just SQL statements.

  • finding out memory allocation hotspots in java

    - by Zamir
    Our GC is working hard and we have some pauses that we want to decrease. We have some memory allocation issues that we want to solve before or while we are tweaking with the actual JVM GC args. I would like to know which objects are making the GC sweat: is there a way to know which objects are evacuated every time the GC is working? is there a way to know which objects are moved between areas every time the GC is working? Is there a way to know which objects are in Eden area? I am working extensively with Jprofiler and Memory Analyzer. I would like to get this information on a running application in my staging environment.

  • Capistrano SSH::AuthenticationFailed, not prompting for password

    - by Sparkmasterflex
    I've been using capistrano successfully for a while now and all of a sudden in every project I've lost the ability to deploy. Environment: os X (Mavericks) ruby 1.9.3p194 rvm (locally, not on server) rails 3.2 and up RubyGems 1.8.25 I'm not using rsa_keys or anything I want capistrano to prompt for user and password. Suddenly it has decided not to ask for a password, but does ask for user. Then it rolls back and gives me the following error. [deploy:update_code] exception while rolling back: Capistrano::ConnectionError, connection failed for: sub.example.com (Net::SSH::AuthenticationFailed: Authentication failed for user [email protected]) connection failed for: sub.example.com (Net::SSH::AuthenticationFailed: Authentication failed for user [email protected]) This has occurred on my personal laptop and my iMac at work. It occurs when deploying to two different servers (both linux) I'm completely at a loss here. Any ideas?

  • Automating SSRS Report Deployment

    - by MikeTWebb
    Hello....I have a web site in 3 environments (DEV/TEST/PROD). The Web Site uses SSRS which also has 3 different environments(DEV/TEST/PROD). Currently, I am deploying the reports using the Manual Deployment mechanism provided in the SSRS Solution (i.e., right click a report and click "Deploy"). I have to manually change the Deployment URLs for each environment. Is there a way to Automate this so that reports are automatically deployeed to PROD and TEST if a change occurs in DEV? I've seen some info on RSScripter but it looks a little tricky/clunky...I was hoping for a more succinct/streamlined solution. Thanks MikeTWebb

  • Which JavaScript Libraries do not rely on a document and navigator object?

    - by Julian Weimer
    I'm currently looking for some libraries which might help me during iPhone Development using Appcelerator Titanium. I've heard that since version 1.0 it isn't dependant on webkit anymore and it makes app-development more exiting of course, please correct me if i'm wrong. As many people out there i love Javascript Frameworks such as JQuery and Mootools much, but they were build specifically to do a great job within a browser and most of the functionality is not needed within the environment Titanium now provides (DOM-Manipulation etc). Is there any other small library of useful functions i can use for development? Thx in advance.
