• IHttpModule not being applied to virtual directory

  - by arthurdent510

  I have a network folder that is mapped to my iis app as a virtual directory and I'm trying to do some authentication for files that are located there with an ihttpmodule. I've verified that the ihttpmodule is firing properly for anything else in my app, just not the files located in virtual directory. Most of what I've found is that the directory can't be listed as an application (which it isn't), and everything should work. The other solution that I found was to add the the module tag to the tag, but that didn't seem to help either. Everything that I've found talks about stopping this from happening. So my question is what could be set that is causing this to not work? Is there a certain execute permission that needs to be set? Any other iis settings that could cause this? It is an mvc app, and this is how my directory structure is laid out: server/app <- my application folder server/app/content/downloads <- downloads is the virtual directory Do I have to add the virtual directory directly under my app directory? Is that part of the problem? I don't have direct control of the server my code is running on, so testing things out is a bit of a pain... so I was looking for some more thoughts before starting to send emails off to my operations people. Thanks!

• Gradle fails injecting dependencies into subprojects using fileTree

  - by Matthias

  Maybe I'm missing something about the way Gradle works. What I have here is a parent project, which only contains configuration, i.e. there won't be any artifact being built when building it, it merely manages and builds all its subprojects. Now the subprojects share some dependency configuration, so I figured what I would do in the root project's build.gradle is: subprojects { dependencies { compile fileTree(dir: 'lib', includes: ['*.jar']) } } that, however, does not work, it fails with a rather obscure error message: A problem occurred evaluating root project 'qype-android' Cause: No signature of method: org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.compile() is applicable for argument types: (org.gradle.api.internal.file.DefaultConfigurableFileTree) values: [file set 'lib'] Possible solutions: module(java.lang.Object) after some trial and error, I could "fix" this issue by applying the 'java' plugin to the parent project. How come? I don't see anywhere from the Gradle docs that a fileTree dependency requires the Java plugin. Even so, why would I need it on the project that is injecting the configuration, as opposed to on the project that is being configured (note that the subprojects all apply the Java plugin themselves)? Does this mean that if I have N different subprojects that are all of varying natures, and apply different plugins, that the parent projects must always apply the set of all plugins beings used somewhere to itself, too?

• ASP.NET: disabling authentication for a single aspx page (custom error page)?

  - by Richard Collette

  I am using a custom error page: <customErrors redirectMode="ResponseRedirect" mode="On" defaultRedirect="Error2.aspx"/> I want to disable authentication for the custom error page because the error being raised is related to an authentication module and I don't want to get into an infinite loop and I want to display a clean error page to the user. I have been trying the following configuration to do that. <location path="Error2.aspx"> <system.web> <authentication mode="None"/> <authorization> <allow users="?"/> <allow users="*"/> </authorization> </system.web> </location> I am getting a System.Configuration.ConfigurationErrorsException for the line that sets the authentication mode. It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS. I have verified that there are no other web.config files in subdirectories under the application's folder. The applications folder is configured as an application in IIS and the error page is at the application's root. File permissions set for the error page in IIS include anonymous and windows authentication (I have tried just anonymous as well).

• Return a list of imported Python modules used in a script?

  - by Jono Bacon

  Hi All, I am writing a program that categorizes a list of Python files by which modules they import. As such I need to scan the collection of .py files ad return a list of which modules they import. As an example, if one of the files I import has the following lines: import os import sys, gtk I would like it to return: ["os", "sys", "gtk"] I played with modulefinder and wrote: from modulefinder import ModuleFinder finder = ModuleFinder() finder.run_script('testscript.py') print 'Loaded modules:' for name, mod in finder.modules.iteritems(): print '%s ' % name, but this returns more than just the modules used in the script. As an example in a script which merely has: import os print os.getenv('USERNAME') The modules returned from the ModuleFinder script return: tokenize heapq __future__ copy_reg sre_compile _collections cStringIO _sre functools random cPickle __builtin__ subprocess cmd gc __main__ operator array select _heapq _threading_local abc _bisect posixpath _random os2emxpath tempfile errno pprint binascii token sre_constants re _abcoll collections ntpath threading opcode _struct _warnings math shlex fcntl genericpath stat string warnings UserDict inspect repr struct sys pwd imp getopt readline copy bdb types strop _functools keyword thread StringIO bisect pickle signal traceback difflib marshal linecache itertools dummy_thread posix doctest unittest time sre_parse os pdb dis ...whereas I just want it to return 'os', as that was the module used in the script. Can anyone help me achieve this?

• Ruby Fileutils.cp_r Permission Denied when :preserve => true

  - by slawley

  Hello, I am trying to implement a poor-man's backup/mirroring script and am having some trouble. I am on Windows-XP, using Ruby's FileUtils module to recursively copy files. So long as I don't set the :preserve flag to true, everything works fine. Works: FileUtils.cp_r('Source_dir', 'Dest_dir', :verbose => true) Doesn't work: FileUtils.cp_r('Source_dir', 'Dest_dir', :verbose => true, :preserve => true) I have full permissions on the Dest_dir as it's on the desktop of my local machine and I just created it. I can copy and delete files and folders, but apparently changing, or maintaining the file attributes with :preserve isn't working. I haven't had a chance to try this on a Mac or linux box, but from reading around online the :preserve flag is a normal stumbling block to come up against in a Windows environment. In a similar line of questioning, what is the default behavior for FileUtils.cp_r when it encounters an existing file at the destination directory? Simply overwrite and replace everything in Destination with whatever is in Source, or can I skip a file with conflicts and just log it for resolution later? (If this should be a separate question, just let me know and I'll make it one.) Thanks, Spencer

• MediaFileUpload of HTML in UTF-8 encoding using Python and Google-Drive-SDK

  - by Victoria

  Looking for example using MediaFileUpload has a reference to the basic documentation for creating/uploading a file to Google Drive. However, while I have code that creates files, converting from HTML to Google Doc format. It works perfectly when they contain only ASCII characters, but when I add a non-ASCII character, it fails, with the following traceback: Traceback (most recent call last): File "d:\my\py\ckwort.py", line 949, in <module> rids, worker_documents = analyze( meta, gd ) File "d:\my\py\ckwort.py", line 812, in analyze gd.mkdir( **iy ) File "d:\my\py\ckwort.py", line 205, in mkdir self.create( **( kw['subop'])) File "d:\my\py\ckwort.py", line 282, in create media_body=kw['media_body'], File "D:\my\py\gdrive2\oauth2client\util.py", line 120, in positional_wrapper return wrapped(*args, **kwargs) File "D:\my\py\gdrive2\apiclient\http.py", line 676, in execute headers=self.headers) File "D:\my\py\gdrive2\oauth2client\util.py", line 120, in positional_wrapper return wrapped(*args, **kwargs) File "D:\my\py\gdrive2\oauth2client\client.py", line 420, in new_request redirections, connection_type) File "D:\my\py\gdrive2\httplib2\__init__.py", line 1597, in request (response, content) = self._request(conn, authority, uri, request_uri, method, body, headers, redirections, cachekey) File "D:\my\py\gdrive2\httplib2\__init__.py", line 1345, in _request (response, content) = self._conn_request(conn, request_uri, method, body, headers) File "D:\my\py\gdrive2\httplib2\__init__.py", line 1282, in _conn_request conn.request(method, request_uri, body, headers) File "C:\Python27\lib\httplib.py", line 958, in request self._send_request(method, url, body, headers) File "C:\Python27\lib\httplib.py", line 992, in _send_request self.endheaders(body) File "C:\Python27\lib\httplib.py", line 954, in endheaders self._send_output(message_body) File "C:\Python27\lib\httplib.py", line 812, in _send_output msg += message_body UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 370: ordinal not in range(128) I don't find any parameter to use to specify what file encoding should be used by MediaFileUpload (My files are using UTF-8).

• Delphi App has "No Debug Info" when Debugging

  - by James L.

  We have built an application that uses packages and components. When we debug the application, the "Event Log" in the IDE often shows the our BPLs are being loaded without debug information ("No Debug Info"). This doesn't make sense because all our packages and EXEs are built with debug. _(each project) | Options | Compiling_ [ x ] Assertions [ x ] Debug information [ x ] Local symbols Symbol reference info = "Reference info" [ ] Use debug .dcus [ x ] Use imported data references _(each project) | Options | Linking_ [ x ] Debug information Map file = Detailed We have 4 projects, all built with runtime pacakges: Core.bpl Components.bpl Plugin.bpl (uses both #1 & #2) MainApp.exe (uses #1) Problems Observed 1) Many times when we debug, the Components.bpl is loaded with debug info, but all values in the "Local Variables" window are blank. If you hover your mouse over a variable in the code, there is no popup, and Evaluate window also shows nothing (the "Result" pane is always blank). 2) Sometimes the Event Log shows "No Debug Info" for various BPLs. For instance, if we activate the Plugin.bpl project and set it's Run | Parameter's Host Application to be the MainApp.exe, and then press F9, all modules seems to load with "Has Debug Info" except for the Plugin.bpl module. When it loads, the Event Log shows "No Debug Info". However, if we close the app and immediately press F9, it will run it again without recompiling anything and this time Plugin.bpl is loaded with debug ("Has Debug Info"). Questions 1) What would cause the "Local Variables" window to not display the values? 2) Why are BPLs sometimes loaded without debug info when the BPL was complied with debug and all the debug files (dcu, map, etc.) are available?

• stuck with enable session state

  - by Shrewd Demon

  hi i have an application wherein i am accessing the Session object in the CommonCode.cs file that resides in the App_Code folder. But when the session object is accessed the application throws me an error: Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \\ section in the application configuration. Now i have already enabled the session state property in the web.config file, here is my code from the web.config file: <pages enableSessionState="true" autoEventWireup="true"> <controls> <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> <add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/> </controls> </pages> I dont understand why am i still getting that error !! please help ! thanks a lot.

• Python - Open default mail client using mailto, with multiple recipients

  - by victorhooi

  Hi, I'm attempting to write a Python function to send an email to a list of users, using the default installed mail client. I want to open the email client, and give the user the opportunity to edit the list of users or the email body. I did some searching, and according to here: http://www.sightspecific.com/~mosh/WWW_FAQ/multrec.html It's apparently against the RFC spec to put multiple comma-delimited recipients in a mailto link. However, that's the way everybody else seems to be doing it. What exactly is the modern stance on this? Anyhow, I found the following two sites: http://2ality.blogspot.com/2009/02/generate-emails-with-mailto-urls-and.html http://www.megasolutions.net/python/invoke-users-standard-mail-client-64348.aspx which seem to suggest solutions using urllib.parse (url.parse.quote for me), and webbrowser.open. I tried the sample code from the first link (2ality.blogspot.com), and that worked fine, and opened my default mail client. However, when I try to use the code in my own module, it seems to open up my default browser, for some weird reason. No funny text in the address bar, it just opens up the browser. The email_incorrect_phone_numbers() function is in the Employees class, which contains a dictionary (employee_dict) of Employee objects, which themselves have a number of employee attributes (sn, givenName, mail etc.). Full code is actually here (http://stackoverflow.com/questions/2963975/python-converting-csv-to-objects-code-design) from urllib.parse import quote import webbrowser .... def email_incorrect_phone_numbers(self): email_list = [] for employee in self.employee_dict.values(): if not PhoneNumberFormats.standard_format.search(employee.telephoneNumber): print(employee.telephoneNumber, employee.sn, employee.givenName, employee.mail) email_list.append(employee.mail) recipients = ', '.join(email_list) webbrowser.open("mailto:%s?subject=%s&body=%s" % (recipients, quote("testing"), quote('testing')) ) Any suggestions? Cheers, Victor

• drupal form textfield #default_value not working

  - by alvin.ng

  I am working on a custom module with multi-page form on drupal 6. I found that #default_value is not working when my '#type' = 'textfield'. However, when '#type'='textarea', it displays correctly with the '#default_value' specified. Basically, I wrote a FormFactory to return different form definition ($form) based on the post parameter received. Initially, it returns the display of directories list, user then selects from radio buttos until a specific directory contains a xml file, it will become edit form. The edit form will have text fields display the data (#default_value) inside the xml file, however the type 'textarea' works here rather than 'textfield'. How can I make my '#default_value' work in this case? Below is the non-working field definition: $form['pageset']['newsTitle'] = array( '#type' => 'textfield', '#title' => 'News Title', '#default_value' => "{$element->newsTitle}", '#rows' => 1, '#required' => TRUE, ); Then I changed it to textarea as shown below to make it work: $form['pageset']['newsTitle'] = array( '#type' => 'textarea', '#title' => 'News Title', '#default_value' => "{$element->newsTitle}", '#rows' => 1, '#required' => TRUE, );

• Displaying progressbar using threading in win 32 applicaition!

  - by kiddo

  In my application I have a simple module were I will read files for some process that will take few seconds..so I thought of displaying a progress bar(using worker thread) while the files are in progress.I have created a thread (code shown below) and also I designed a dialog window with progress control.I used the function MyThreadFunction below to display the progressbar but it just shows only one time and disappears,I am not sure how to make it work.I tried my best inspite of the fact that I am new to threading. reading files void ReadMyFiles() { for(int i = 0; i < fileCount ; fileCount++) { CWinThread* myThread = AfxBeginThread((AFX_THREADPROC)MyThreadFunction,NULL); tempState = *(checkState + index); if(tempCheckState == NOCHECKBOX) { //my operations } else//CHECKED or UNCHECKED { //myoperation } myThread->PostThreadMessage(WM_QUIT,NULL,NULL); } } thread functions UINT MyThreadFunction(LPARAM lparam) { HWND dialogWnd = CreateWindowEx(0,WC_DIALOG,L"Proccessing...",WS_OVERLAPPEDWINDOW|WS_VISIBLE, 600,300,280,120,NULL,NULL,NULL,NULL); HWND pBarWnd = CreateWindowEx(NULL,PROGRESS_CLASS,NULL,WS_CHILD|WS_VISIBLE|PBS_MARQUEE,40,20,200,20, dialogWnd,(HMENU)IDD_PROGRESS,NULL,NULL); MSG msg; PostMessage( pBarWnd, PBM_SETRANGE, 0, MAKELPARAM( 0, 100 ) ); PostMessage(pBarWnd,PBM_SETPOS,0,0); while(PeekMessage(&msg,NULL,NULL,NULL,PM_NOREMOVE)) { if(msg.message == WM_QUIT) { DestroyWindow(dialogWnd); return 1; } AfxGetThread()->PumpMessage(); Sleep(40); } return 1; }

• heterogeneous comparisons in python3

  - by Matt Anderson

  I'm 99+% still using python 2.x, but I'm trying to think ahead to the day when I switch. So, I know that using comparison operators (less/greater than, or equal to) on heterogeneous types that don't have a natural ordering is no longer supported in python3.x -- instead of some consistent (but arbitrary) result we raise TypeError instead. I see the logic in that, and even mostly think its a good thing. Consistency and refusing to guess is a virtue. But what if you essentially want the python2.x behavior? What's the best way to go about getting it? For fun (more or less) I was recently implementing a Skip List, a data structure that keeps its elements sorted. I wanted to use heterogeneous types as keys in the data structure, and I've got to compare keys to one another as I walk the data structure. The python2.x way of comparing makes this really convenient -- you get an understandable ordering amongst elements that have a natural ordering, and some ordering amongst those that don't. Consistently using a sort/comparison key like (type(obj).__name__, obj) has the disadvantage of not interleaving the objects that do have a natural ordering; you get all your floats clustered together before your ints, and your str-derived class separates from your strs. I came up with the following: import operator def hetero_sort_key(obj): cls = type(obj) return (cls.__name__+'_'+cls.__module__, obj) def make_hetero_comparitor(fn): def comparator(a, b): try: return fn(a, b) except TypeError: return fn(hetero_sort_key(a), hetero_sort_key(b)) return comparator hetero_lt = make_hetero_comparitor(operator.lt) hetero_gt = make_hetero_comparitor(operator.gt) hetero_le = make_hetero_comparitor(operator.le) hetero_ge = make_hetero_comparitor(operator.gt) Is there a better way? I suspect one could construct a corner case that this would screw up -- a situation where you can compare type A to B and type A to C, but where B and C raise TypeError when compared, and you can end up with something illogical like a > b, a < c, and yet b > c (because of how their class names sorted). I don't know how likely it is that you'd run into this in practice.

• .NET 4.0 Forms Authentication change?

  - by James Koch

  I'm seeing some new behavior in Forms Authentication after upgrading to .NET 4.0. This occurs only on IIS 6, not on 7. Background - In web.config, we configure Forms Authentication, and then use <authorization tags to globally deny anonymous/unauthenticated users access. Then we explicitly allow access to a login.aspx page using a <location tag. Generally, this works fine, as it did when we were on .NET 2.0 (3.5). The issue only occurs when we visit the root path of the site, ie "http://myserver/". Our default document is configured in IIS to be login.aspx. Under .NET 4.0, upon visiting that URL, we're redirected to "http://myserver/login.aspx?ReturnUrl=/". If you log in from here, you're logged in and returned back at the log in page (yuck). Just wanted to post this here to see if anyone else is experiencing this. It's not listed on any "breaking changes" documentation I've been able to find. Either I'm missing something, or the UrlAuthorization module has changed and is no longer "smart" about IIS default documents.

• Best practises for Magento Deployment

  - by Spongeboy

  I am looking setting up a deployment process for a highly customised Magento site, and was wondering how other people do this. I will be setting up dev, UAT and prod environments. All the Magento files will be in source control (SVN). At this stage, I can't see any requirements for changing the DB, so the 3 databases will be manually maintained. Specifically, How do you apply Magento upgrades? (Individually in each env, or on dev then roll out, or just give up on upgrades?) What files/folders do leave alone in each environment (e.g. magento/app/etc/local.xml) Do you restrict developers to editing specific files/folders? Do you restrict theme designers to editing specific files/folders? How do you manage database changes? Theme Designer Files/Folders Designers can restricted to editing the following folders- app/design/frontend/your_interface/your_theme/layout/ app/design/frontend/your_interface/your_theme/template/ app/design/frontend/your_interface/your_theme/locale/ skin/frontend/your_interface/your_theme/ Extension Developer Files/Folders Extension developers can edit the following folders/files- /app/code/local /app/etc/modules/<Namespace>_<Module>.xml Database environment management As the store's base URL is stored in the database, you cannot just copy databases between environments. Options include- Overriding the base url in php. Blog article on setting up dev and staging databases Changing the base url in the database after copying. (Where is this stored?) Doing a MySQLDump or backup, then doing a replace on the URL in the SQL file.

• Python and Unicode: How everything should be Unicode

  - by A A

  Forgive if this a long a question: I have been programming in Python for around six months. Self taught, starting with the Python tutorial and then SO and then just using Google for stuff. Here is the sad part: No one told me all strings should be Unicode. No, I am not lying or making this up, but where does the tutorial mention it? And most examples also I see just make use of byte strings, instead of Unicode strings. I was just browsing and came across this question on SO, which says how every string in Python should be a Unicode string. This pretty much made me cry! I read that every string in Python 3.0 is Unicode by default, so my questions are for 2.x: Should I do a: print u'Some text' or just print 'Text' ? Everything should be Unicode, does this mean, like say I have a tuple: t = ('First', 'Second'), it should be t = (u'First', u'Second')? I read that I can do a from __future__ import unicode_literals and then every string will be a Unicode string, but should I do this inside a container also? When reading/ writing to a file, I should use the codecs module. Right? Or should I just use the standard way or reading/ writing and encode or decode where required? If I get the string from say raw_input(), should I convert that to Unicode also? What is the common approach to handling all of the above issues in 2.x? The from __future__ import unicode_literals statement? Sorry for being a such a noob, but this changes what I have been doing for a long time and so clearly I am confused.

• Assembly unavailable after Web.config change

  - by tags2k

  I'm using a custom framework that uses reflection to do a GetTypeByName(string fullName) on the fully-qualified type name that it gets from the database, to create an instance of said type and add it to the page, resulting in a standard modular kind of thing. GetTypeByName is a utility function of mine that simply iterates through Thread.GetDomain().GetAssemblies(), then performs an assembly.GetType(fullName) to find the relevant type. Obviously this result gets cached for future reference and speed. However, I'm experiencing some issues whereby if the web.config gets updated (and, in some scarier instances if the application pool gets recycled) then it will lose all knowledge of certain assemblies, resulting in the inability to render an instance of the module type. Debugging shows that the missing assembly literally does not exist in the current thread assemblies list. To get around this I added a second check which is a bit dirty but recurses through the /bin/ directory's DLLs and checks that each one exists in the assemblies list. If it doesn't, it loads it using Assembly.Load and fixing the context issue thanks to 'Solving the Assembly Load Context Problem'. This would work, only it seems that (and I'm aware this shouldn't be possible) some projects still have access to the missing assembly, for example my actual web project rather than the framework itself - and it then complains that duplicate references have been added! Has anyone ever heard of anything like this, or have any ideas why an assembly would simply drop out of existence on a config change? Short of a solution, what is the most elegant workaround to get all the assemblies in the bin to reload? It needs to be all in one "hit" so that the site visitors don't see any difference other than a small delay, so an app_offline.htm file is out of the question. Programatically renaming a DLL in the bin and then naming it back does work, but requires "modify" permissions for the IIS user account, which is insane. Thanks for any pointers the community can gather!

• Turbogears 2.0 with Python 2.6

  I've tried to install TurboGears 2.0 with Python 2.6 on both Windows 7 and Windows XP, but both give the same error: File "D:\PythonProjects\tg2env\Scripts\paster-script.py", line 8, in <module> load_entry_point('pastescript==1.7.3', 'console_scripts', 'paster')() File "D:\PythonProjects\tg2env\lib\site-packages\pastescript-1.7.3-py2.6.egg\paste\script\command.py", line 73, in run commands = get_commands() File "D:\PythonProjects\tg2env\lib\site-packages\pastescript-1.7.3-py2.6.egg\paste\script\command.py", line 115, in get_ plugins = pluginlib.resolve_plugins(plugins) File "D:\PythonProjects\tg2env\lib\site-packages\pastescript-1.7.3-py2.6.egg\paste\script\pluginlib.py", line 81, in res pkg_resources.require(plugin) File "D:\PythonProjects\tg2env\lib\site-packages\setuptools-0.6c9-py2.6.egg\pkg_resources.py", line 626, in require File "D:\PythonProjects\tg2env\lib\site-packages\setuptools-0.6c9-py2.6.egg\pkg_resources.py", line 524, in resolve pkg_resources.DistributionNotFound: zope.sqlalchemy>=0.4: Not Found for: City_Guide (did you run python setup.py develop?) Now, according to the documentation on the main site, TurboGears 2.0 supports Python 2.6 in this page: TurboGears works with any version of python between 2.4 and 2.6. The most widely deployed version of python at the moment of this writing is version 2.5. Both python 2.4 and python 2.6 require additional steps which will be covered in the appropriate sections. But they never mention those steps in the documentation.

• backbone.js Model.get() returns undefined, scope using coffeescript + coffee toaster?

  - by benipsen

  I'm writing an app using coffeescript with coffee toaster (an awesome NPM module for stitching) that builds my app.js file. Lots of my application classes and templates require info about the current user so I have an instance of class User (extends Backbone.Model) stored as a property of my main Application class (extends Backbone.Router). As part of the initialization routine I grab the user from the server (which takes care of authentication, roles, account switching etc.). Here's that coffeescript: @user = new models.User @user.fetch() console.log(@user) console.log(@user.get('email')) The first logging statement outputs the correct Backbone.Model attributes object in the console just as it should: User _changing: false _escapedAttributes: Object _pending: Object _previousAttributes: Object _silent: Object attributes: Object account: Object created_on: "1983-12-13 00:00:00" email: "[email protected]" icon: "0" id: "1" last_login: "2012-06-07 02:31:38" name: "Ben Ipsen" roles: Object __proto__: Object changed: Object cid: "c0" id: "1" __proto__: ctor app.js:228 However, the second returns undefined despite the model attributes clearly being there in the console when logged. And just to make things even more interesting, typing "window.app.user.get('email')" into the console manually returns the expected value of "[email protected]"... ? Just for reference, here's how the initialize method compiles into my app.js file: Application.prototype.initialize = function() { var isMobile; isMobile = navigator.userAgent.match(/(iPhone|iPod|iPad|Android|BlackBerry)/); this.helpers = new views.DOMHelpers().initialize().setup_viewport(isMobile); this.user = new models.User(); this.user.fetch(); console.log(this.user); console.log(this.user.get('email')); return this; }; I initialize the Application controller in my static HTML like so: jQuery(document).ready(function(){ window.app = new controllers.Application(); }); Suggestions please and thank you!

• Python socket error on UDP data receive. (10054)

  - by Charles

  I currently have a problem using UDP and Python socket module. We have a server and clients. The problem occurs when we send data to a user. It's possible that user may have closed their connection to the server through a client crash, disconnect by ISP, or some other improper method. As such, it is possible to send data to a closed socket. Of course with UDP you can't tell if the data really reached or if it's closed, as it doesn't care (atleast, it doesn't bring up an exception). However, if you send data and it is closed off, you get data back somehow (???), which ends up giving you a socket error on sock.recvfrom. [Errno 10054] An existing connection was forcibly closed by the remote host. Almost seems like an automatic response from the connection. Although this is fine, and can be handled by a try: except: block (even if it lowers performance of the server a little bit). The problem is, I can't tell who this is coming from or what socket is closed. Is there anyway to find out 'who' (ip, socket #) sent this? It would be great as I could instantly just disconnect them and remove them from the data. Any suggestions? Thanks.

• Is NUnit's ExpectedExceptionAttribute only way to test if something raises an exception?

  - by Dariusz Walczak

  Hello, I'm completely new at C# and NUnit. In Boost.Test there is a family of BOOST_*_THROW macros. In Python's test module there is TestCase.assertRaises method. As far as I understand it, in C# with NUnit (2.4.8) the only method of doing exception test is to use ExpectedExceptionAttribute. Why should I prefer ExpectedExceptionAttribute over - let's say - Boost.Test's approach? What reasoning can stand behind this design decision? Why is that better in case of C# and NUnit? Finally, if I decide to use ExpectedExceptionAttribute, how can I do some additional tests after exception was raised and catched? Let's say that I want to test requirement saying that object has to be valid after some setter raised System.IndexOutOfRangeException. How would you fix following code to compile and work as expected? [Test] public void TestSetterException() { Sth.SomeClass obj = new SomeClass(); // Following statement won't compile. Assert.Raises( "System.IndexOutOfRangeException", obj.SetValueAt( -1, "foo" ) ); Assert.IsTrue( obj.IsValid() ); } Edit: Thanks for your answers. Today, I've found an It's the Tests blog entry where all three methods described by you are mentioned (and one more minor variation). It's shame that I couldn't find it before :-(.

• spam and dirty words comment post filtering in python (django)

  - by sintaloo

  Hi All, My basic question is how to filter spam and dirty words in a comment post system under python (django). I have a collection of phrases (approximately 3000 phrases) to be filtered. Question (1), are there any existing open source python (or django) package/module/plugin which can handle this job? I knew there was one called Akismet. But from what I understood, it will not solve my problem. Akismet is just a web service and filter the words dictionary defined by Akismet. But I have my own collection of words. Please correct me if I am wrong. Question (2), If there is no such open source package I can use, how to create my own one? The only thing I can think of it's to use regular expression and join all the word phrases with 'or' in a regular expression. but I have 3000 phrases, I think it won't work in term of performance and filter every comment post. any suggestions where should I start from? Thank you very much for your help and time.

• Could Python's logging SMTP Handler be freezing my thread for 2 minutes?

  - by Oddthinking

  A rather confusing sequence of events happened, according to my log-file, and I am about to put a lot of the blame on the Python logger, which is a bold claim. I thought I should get some second opinions about whether what I am saying could be true. I am trying to explain why there is are several large gaps in my log file (around two minutes at a time) during stressful periods for my application when it is missing deadlines. I am using Python's logging module on a remote server, and have set-up, with a configuration file, for all logs of severity of ERROR or higher to be emailed to me. Typically, only one error will be sent at a time, but during periods of sustained problems, I might get a dozen in a minute - annoying, but nothing that should stress SMTP. I believe that, after a short spurt of such messages, the Python logging system (or perhaps the SMTP system it is sitting on) is encountering errors or congestion. The call to Python's log is then BLOCKING for two minutes, causing my thread to miss its deadlines. (I was smart enough to move the logging until after the critical path of the application - so I don't care if logging takes me a few seconds, but two minutes is far too long.) This seems like a rather awkward architecture (for both a logging system that can freeze up, and for an SMTP system (Ubuntu, sendmail) that cannot handle dozens of emails in a minute**), so this surprises me, but it exactly fits the symptoms. Has anyone had any experience with this? Can anyone describe how to stop it from blocking? ** EDIT: I actually counted. A little under 4000 short emails in two hours. So far more than I suggested, sorry. But enough to over-fill a Sendmail's buffers?
