  • Albacore msbuild task problem

    - by Dejan
    Just updated albacore to version 0.14 and ran into a major problem. My current environment is: Ruby 1.9.1 Rake 0.8.7 Albacore 0.1.4 The problem is that as of now all my rake build throw a funny little exception: undefined method 'push' for #<Enumerator:0x???????> So far I have traced the problem to albacore msbuild.rb line 38 and 26. To be honest I just don't have a clue why this is happening. As a little help here is the rake task that is turning my hear Grey :) desc "Build solution" msbuild :build => :prepareOutput do |msb| msb.properties :configuration => :Release msb.targets :Clean, :Build msb.solution = "../xxx/xxx/xxx.sln" end

  • Recommendations for 'C' Project architecture guidelines?

    - by SiegeX
    Now that I got my head wrapped around the 'C' language to a point where I feel proficient enough to write clean code, I'd like to focus my attention on project architecture guidelines. I'm looking for a good resource that coves the following topics: How to create an interface that promotes code maintainability and is extensible for future upgrades. Library creation guidelines. Example, when should I consider using static vs dynamic libraries. How to properly design an ABI to cope with either one. Header files: what to partition out and when. Examples on when to use 1:1 vs 1:many .h to .c Anything you feel I missed but is important when attempting to architect a new C project. Ideally, I'd like to see some example projects ranging from small to large and see how the architecture changes depending on project size, function or customer. What resource(s) would you recommend for such topics?

  • visual studio 2005 is deleting the .svn folder in the bin\Debug directory - how to prevent this?

    - by M K Saravanan
    For some reason I need to check in a couple of files in the bin\Debug directory. For the past few weeks, I am noticing a strange behaviour from VS2005. Every time I recompile the code, it is deleting the .svn folder in the bin\Debug directory and hence svn is showing "obstructed" error. Even svn clean up doesn't help due to missing .svn folder. Is there any settings on VS2005 to prevent this? In the first place, why it is deleting .svn folder? This thread http://svn.haxx.se/tsvnusers/archive-2008-10/0019.shtml discuss about it but no useful solution to prevent this from happening. Any other suggestions?

  • Fabfiles With Command Line Arguments

    - by phasetwenty
    Is there a clean way to have your fabfile take command line arguments? I'm writing an installation script for a tool that I want to be able to specify an optional target directory via the command line. I wrote some code to test what would happen if I passed in some command line arguments: # fabfile.py import sys def install(): _get_options() def _get_options(): print repr(sys.argv[1:]) A couple of runs: $ fab install ['install'] Done. $ fab install --electric-boogaloo Usage: fab [options] <command>[:arg1,arg2=val2,host=foo,hosts='h1;h2',...] ... fab: error: no such option: --electric-boogaloo

  • Remove innerHTML from div

    - by coffeeaddict
    I'm trying to clear the div's innerHTML before repopulating it. I tried removeData() but once that's called, when I try to add the data, I get nothing from the next line after remove whereas if I remove the removeData() it's fine again. I just want to clear out any previous content in that div before I re-populate it. divToUpdate.removeData(); //clean out any existing innerHTML div content first divToUpdate.html(data); It looks like it never gets to my divToUpdate.html(data) for some reason after it calls that removeData();

  • Maven eclipse does not add a dependency

    - by Calm Storm
    I have the following snippet in my pom.xml <dependency> <groupId>aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>1.5.3</version> </dependency> and in one of my Java files I refer a class org.aspectj.lang.ProceedingJoinPoint. When I do a "mvn clean install" it compiles and builds fine but when I do an eclipse:eclipse, and import the project in eclipse it gives me an error The import org.aspectj cannot be resolved. I checked the .classpath file that was generated and it does not have an entry to this file. I tried a "mvn dependency:tree" and it lists this fine. Can someone tell me what is going wrong here?

  • Writing String.trim() in C

    - by Phoenix
    Hi guys, I was writing the String trim method in c and this is the code I came up with. I think it does the job of eliminating leading and trailing whitespaces however, I wish the code could be cleaner. Can you suggest improvements. void trim(char *String) { int i=0;j=0; char c,lastc; while(String[i]) { c=String[i]; if(c!=' ') { String[j]=c; j++; } else if(lastc!= ' ') { String[j]=c; j++; } lastc = c; i++; } Does this code look clean ??

  • Is possible to auto-import a module from a diferent subfolder in other subfolder?

    - by mamcx
    I have a kind of plugin system, with this layout: - Python -- SDK -- Plugins ---- Plugin1 ---- Plugin2 All 3 have a __init__.py file. I wonder if is possible to be able to do import SDK from any plugin (as if SDK was in the site-packages folder). I'm in a situation where need to deploy, update, delete, add or change SDK files or any of the plugins under non-admin accounts, and wonder if I can get SDK in a clean way (I could sys.path.append in all plugins but I wonder if exist a better option). I imagine that using this in the Plugins init coulkd work: import sys import os ROOT_DIR = os.path.abspath(os.path.join(os.path.dirname(__file__),'..')) print ROOT_DIR sys.path.append( ROOT_DIR ) But clearly is not executed this code (I imagine init was auto-magicalled executed in the load of the module :( )

  • Ambiguous Generic restriction T:class vs T:struct

    - by Maslow
    This code generates a compiler error that the member is already defined with the same parameter types. private T GetProperty<T>(Func<Settings, T> GetFunc) where T:class { try { return GetFunc(Properties.Settings.Default); } catch (Exception exception) { SettingReadException(this,exception); return null; } } private TNullable? GetProperty<TNullable>(Func<Settings, TNullable> GetFunc) where TNullable : struct { try { return GetFunc(Properties.Settings.Default); } catch (Exception ex) { SettingReadException(this, ex); return new Nullable<TNullable>(); } } Is there a clean work around?

  • Why do C# automatic properties not support default values like VB 2010?

    - by Rob van Groenewoud
    Looking at the new VB 2010 features, I stumbled upon support for Auto-Implemented Properties. Since I'm working with C#, this seemed quite familiar, but I noticed that VB did add a feature I would love to have in C#: setting a arbitrary default value for the auto-implemented property: I really like the clean usage of auto-properties in C#. This would save us the effort of introducing a backing field and hooking it up to the property everytime we simply need a default value, thereby cluttering up the code unnecessarily. I was wondering why this wasn't introduced in C# as well? What could be the rationale for not doing this? Is a syntax discussion going on, or are there technical limitations to implementing this?

  • What causes "java.lang.IncompatibleClassChangeError: vtable stub"?

    - by JimN
    What causes "java.lang.IncompatibleClassChangeError: vtable stub"? In our application, we have seen this error pop up randomly and very seldom (just twice so far, and we run it a lot). It is not readily reproducible, even when restarting the app, using the same jvm/jars without rebuilding. As for our build process, we clean all classes/jars and rebuild them, so it's not the same problem as others have encountered where they made a change in one class and didn't recompile some other dependent classes. This is unlike some of the other questions related to IncompatibleClassChangeError -- none of them mention "vtable stub". In fact, there are surprisingly few google results when searching for "IncompatibleClassChangeError "vtable stub"".

  • What are all the disadvantages of using files as a means of communicating between two processes?

    - by Manny
    I have legacy code which I need to improve for performance reasons. My application comprises of two executables that need to exchange certain information. In the legacy code, one exe writes to a file ( the file name is passed as an argument to exe) and the second executable first checks if such a file exists; if does not exist checks again and when it finds it, then goes on to read the contents of the file. This way information in transferred between the two executables. The way the code is structured, the second executable is successful on the first try itself. Now I have to clean this code up and was wondering what are the disadvantages of using files as a means of communication rather than some inter-process communication like pipes.Is opening and reading a file more expensive than pipes? Are there any other disadvantages? And how significant do you think would be the performance degradation. The legacy code is run on both windows and linux.

  • Find missing birth days in Apple Addressbook

    - by Felix Ogg
    I am trying to clean the holes out of my Mac address book. As a first step I want to ask all my friends for their birth day, to be able to congratulate them with cheesy Hallmark cards. I need a "group" in my address book, to mailmerge personalized messages from. This is the Applescript I came up with: tell application "Address Book" make new group with properties {name:"No Birthday"} set birthdayPeople to (get every person whose birth date is greater than date "Monday, January 1, 1900 12:00:00 AM") repeat with i from 1 to number of items in people set thePerson to item i of people if not (birthdayPeople contains thePerson) then add thePerson to group "No Birthday" end if end repeat save end tell It breaks, but from the error messages I cannot deduce what is wrong: Result: error "Can’t make «class azf4» id \"05F770BA-7492-436B-9B58-E24F494702F8:ABPerson\" of application \"Address Book\" into type vector." number -1700 from «class azf4» id "05F770BA-7492-436B-9B58-E24F494702F8:ABPerson" to vector (BTW: Did I mention this is my first AppleScript code, EVER? So, if this code can be simplified, or made more elegant, that is welcome too.)

  • Resharper Autocomplete Issue

    - by Gene
    Hi All, I've been using resharper with the resharper automplete off (just find VS better for my purposes currently), but despite trying every setting I've tried, whenever I use a resharper template (such as tab-completing an if - if block), the resharper autocomplete dialog comes up in addition to the visual studio dialog (thus if they don't autocomplete to the same thing, or I accidentally hit enter, whatever I originally typed is replaced with the wrong resharper suggestion, effectively highlighting why I turned it off in the first place). A. Has anyone every seen this before? (I ask since I might have turned on/off a number of settings in a strange/incompatible way and perhaps a clean install might clear it up.) B. Any suggestions? :) (Visual Studio 08 SP1, Resharper 4.5.2 - only other tools installed are DevExpress, but they have long since been disabled) Thanks all!

  • Android and SQLite using the SQLiteOpenHelper

    - by tunneling
    I have a SQLite database, and several tables within that database. I am developing a DBAdapter for each table within the database. (reference Reto Meier's Professional Android 2 Application Development, Listing 7.1). I am using the adb shell to interface with the database from the command line and see that the database is being populated as I expect. Occasionally, I want to drop a table so that I can ensure it's being built properly, from scratch. The problem is that SQLiteOpenHelper only checks to see if the database exists. Is there a typical solution to writing a helper to also see that the table(s) exists? Basically once I drop a table, the helper checks to see that the database exists and assumes all is well. Also, the CREATE_DATABASE string used in the reference above only creates the one table. Should I consider using the DBAdapter for an adapter to ALL of my tables? That doesn't seem as clean to me.

  • Getting Bad file descriptor when running Tornado AsyncHTTPTestCase

    - by Will
    When running a test using the Tornado AsyncHTTPTestCase I'm getting a stack trace that isn't related to the test. The test is passing so this is probably happening on the test clean up? I'm using Python 2.7.2, Tornado 2.2. The test code is: class AllServersHandlerTest(AsyncHTTPTestCase): endpoint = AllServersHandler.endpoint # '/rest/test/' def test_server_status_with_advertiser(self): on_new_host(None, '127.0.0.1') response = self.fetch(self.endpoint, method='GET') result = json.loads(response.body, 'utf8').get('data') self.assertEquals(['127.0.0.1'], result) The test passes ok, but I get the following stack trace from the Tornado server. OSError: [Errno 9] Bad file descriptor INFO:root:200 POST /rest/serverStatuses (127.0.0.1) 0.00ms DEBUG:root:error closing fd 688 Traceback (most recent call last): File "C:\Python27\Lib\site-packages\tornado-2.2-py2.7.egg\tornado\ioloop.py", line 173, in close os.close(fd) OSError: [Errno 9] Bad file descriptor Any ideas how to cleanly shutdown the test case?

  • Removing all Matching Classes in jQuery

    - by Seth Duncan
    Hi I have an li element that will have something along the lines of this for a declaration <li class="module ui-helper-fix"> And I can dynamically change the color of the module by adding on classes (That are provided dynamically through DB calls) the end result being <li class="module ui-helper-fix module-green"> or <li class="module ui-helper-fix module-default"> Well I am fine with changing the color by adding on a new module-WHATEVER class but what I would like to do is remove any class that matches module-XXXX so it starts with a clean slate and then add on the class module-crimson. So how do I remove all classes that match module-xxx first ? Keeping in mind I don't want to remove the base module class. Thanks. -Seth

  • Error messages for model validation using data annotations

    - by oneBelizean
    Given the follow classes: using System.ComponentModel.DataAnnotations; public class Book{ public Contact PrimaryContact{get; set;} public Contact SecondaryContact{get; set;} [Required(ErrorMessage="Book name is required")] public string Name{get; set;} } public class Contact{ [Required(ErrorMessage="Name is required")] public string Name{get; set;} } Is there a clean way I can give a distinct error message for each instance of Contact in Book using DataAnnotations? For example, if the name was missing from the PrimaryContact instance the error would read "primary contact name is required". My current solution is to create a validation service that checks the model state for field errors then remove said errors and add them back using the specific language I'd like.

  • Overwriting arguments object for a Javascript function

    - by Ian Storm Taylor
    If I have the following: // Clean input. $.each(arguments, function(index, value) { arguments[index] = value.replace(/[\W\s]+/g, '').toLowerCase(); }); Would that be a bad thing to do? I have no further use for the uncleaned arguments in the function, and it would be nice not to create a useless copy of arguments just to use them, but are there any negative effects to doing this? Ideally I would have done this, but I'm guessing this runs into problems since arguments isn't really an Array: arguments = $.map(arguments, function(value) { return value.replace(/[\W\s]+/g, '').toLowerCase(); }); Thanks for any input. EDIT: I've just realized that both of these are now inside their own functions, so the arguments object has changed. Any way to do this without creating an unnecessary variable?

  • Restfull authentication between two GAE apps.

    - by user259349
    Hello everyone, i am trying to write a restful google app engine application (python) that accepts requests only from another GAE that i wrote. I dont like any of the ways that i thought of to get this done, please advice if you know of something better than: Get SSL setup, and simply add the credentials on the request that my consuming app will send. I dont like it cause SSL will slow things down. Security by obsecurity. Pass a long number by my consuming app that is in Xmod0, where X is a secret number that both applications know. I just,,,, dont like this. Check the HTTP header to see where is the request coming from. This option is the one that i hate the least, not alot of processing, and spoofing an HTTP request is not really worth it, for my application's data. Is there any other clean solution for this?

  • How to do relative imports in Python?

    - by Joril
    Imagine this directory structure: app/ __init__.py sub1/ __init__.py mod1.py sub2/ __init__.py mod2.py I'm coding mod1, and I need to import something from mod2. How should I do it? I tried from ..sub2 import mod2 but I'm getting an "Attempted relative import in non-package". I googled around but found only "sys.path manipulation" hacks. Isn't there a clean way? Edit: all my __init__.py's are currently empty Edit2: I'm trying to do this because sub2 contains classes that are shared across sub packages (sub1, subX, etc.). Edit3: The behaviour I'm looking for is the same as described in PEP 366 (thanks John B)

  • deep injection - spring

    - by Bob
    What is the best way (or options) for accessing spring components at layers deep within the application that aren't managed by spring? For example, I have a low level utility POJO class into which I need to autowire/inject a spring component. I'll call it LowLevelHelper. There are multiple classes that use LowLevelHelper - most are layers away from anything that is hooked up with spring. One option would be to make all the layers in to spring components, but that seems like I'm hacking my design to force spring to help me. I have some complex things going on that won't be nearly as clean if I have to @Autowire all the pieces and don't new anything. Another option might be to manually inject the component in the low level class, but I'm not really sure if this is possible or the right solution.

  • Releasing NSData causes exception...

    - by badmanj
    Hi, Can someone please explain why the following code causes my app to bomb? NSData *myImage = UIImagePNGRepresentation(imageView.image); : [myImage release]; If I comment out the 'release' line, the app runs... but a few times calling the function containing this code and I get a crash - I guess caused by a memory leak. Even if I comment EVERYTHING else in the function out and just leave those two lines, when the release executes, the app crashes. I'm sure this must be a newbie "you don't know how to clean up your mess properly" kind of thing ;-) Cheers, Jamie.

  • jqueryForm and empty uploads

    - by Aiden Bell
    Hi All, Been scratching my head for too long on this: Using jquery.form, (http://malsup.com/jquery/form) with PHP ... my $_FILES['someimage'] gets set but the error number is always UPLOAD_ERR_NO_FILE, size is also 0. The JavaScript: $('form input[type=file]').change(function(){ $(this).clone().appendTo('#imgform'); $('#imgform').ajaxForm(); $('#imgform').ajaxSubmit( { type:'POST' } ); }); Which appends to: <form id="imgform" method="POST" action="/api/images.php" enctype="multipart/form-data"></form> From another form which has bog-standard file inputs. PHP logs are clean, but var_dumping $_FILES always shows that the index is set to the name of the form element ... but no data. Thanks guys! (Sorry, I know jQuery-like questions are too frequent round these parts).

  • How do I mock a custom field that is deleted so that south migrations run?

    - by muhuk
    I have removed an app that contained a couple of custom fields from my project. Now when I try to run my migrations I get ImportError, naturally. These fields were very basic customizations like below: from django.db.models.fields import IntegerField class SomeField(IntegerField): def get_internal_type(self): return "SomeField" def db_type(self, connectio=None): return 'integer' def clean(self, value): # some custom cleanup pass So, none of them contain any database level customizations. When I removed this code, I've created migrations so the subsequent migration all ran fine. But when I try to run them on a pre-deletion database I realized my mistake. I can re-create a bare-bones app and make these imports work, but Ideally I would like to know if South has a mechanism to resolve these issues? Or is there any best practises? It would be cool if I could solve these issues just by modifying my migrations and not touching the codebase. (Django 1.3, South 0.7.3)
