• How do I get google guice to inject a custom logger, say a commons-logging or log4j logger

  - by Miguel Silva

  Google guice has a built-in logger binding (http://code.google.com/p/google-guice/wiki/BuiltInBindings). But what if I want to use a commons-logging or log4j logger? Can I get guice to inject a Log created by LogFactory.getLog(CLASS.class) But having the same behavior as in built-in binding: The binding automatically sets the logger's name to the name of the class into which the Logger is being injected.. Does it even makes sense? Or shout I simply use the built-in java Logger? Or just use commons-logging without injections?

• Pros and cons of using JSON for WCF service

  - by brz dot net

  What are the pros and cons of the following 2 cases: Case I: Traditional way: Add service reference in project. Create object and Get data from service on server side and bind to asp.net grid. Case II: Update Service for JSON behavior. Add service reference in project. Call service from javascript to get data. Bind data to jquery grid. Which one is the best approach and why?(Not developer point of view) If there is another approach which is more optimized, please explain it.

• PHP text output in clauses

  - by arik-so

  Hello. I am working on a PHP project. There, I often use following syntax to output text in a cluase: if($boolean){ ?> output text <? }else{ ?> alternative <? } On my computer, this works perfectly well. I use XAMPP foer Mac OS X. But when I send the files to my coworker, these outputs often do not work and the compiler complains about having reached an unexpected $end of file. This occurs especially often when there is a tag in the output. We have to replace the means of output with echo. What's the reason for this strange behavior of the compiler? Is the above-mention syntax of outputting text wrong?

• Tomcat gzip while chunked issue

  - by hoodoos

  I'm expiriencing some problem with one of my data source services. As it says in HTTP response headers it's running on Apache-Coyote/1.1. Server gives responses with Transfer-Encoding: chunked, here sample response: HTTP/1.1 200 OK Server: Apache-Coyote/1.1 Content-Type: text/xml;charset=utf-8 Transfer-Encoding: chunked Content-Encoding: gzip Date: Tue, 30 Mar 2010 06:13:52 GMT And problem is when I'm requesting server to send gzipped request it often sends not full response. I recieve response, see that last chunk recieved, but then after ungzipping I see that response is partial. I never seen such behavior with gzip turned off in request headers. So my question is: is it common tomcat issue? maybe one of it's mod which is doing compression? Or maybe it maybe some kind of proxy issue? I can't tell about versions of tomcat or what gzip mod they use, but feel free to ask, i'll try ask my service provider. Thanks.

• Jquery click() not behaving like user click

  - by rpiontek

  I have searched for a solution to this for the last several hours but to no avail. When I click on a button that has a return false in OnClientClick, no postback occurs to the server. When I use jquery to trigger the click function of the button, OnClientClick fires first, but regardless of the return value, a postback occurs. Here's a simple sample... So, in this example, when Button1 is clicked normally, no postback occurs. When Button2 is clicked, a postback always occurs. Is this a bug or intended behavior?

• Ruby on Rails protect_from_forgery best practice

  - by randombits

  I'm currently working on building a RESTful web api with ruby on rails. I haven't bothered putting a proper authentication scheme into the API yet as I'm ensuring that tests and the basic behavior of the API is working all locally first. Upon testing non-HTTP GET type requests such as HTTP POST/DELETE/PUT, stuff chokes because protect_from_forgery is on by default. How does this work when I'm working in practice since essentially the idea is in a RESTful API that there is no state. The client does not have a session or a cookie associated with the server. Each request is an atomic, self-executed request. The user will supply some credentials to ensure they are who they say they are, but other than that, does protect_from_forgery make sense at this point? Should it remain enabled?

• IE7 float/clear bug

  - by alex

  I am having the weirdest behavior in IE7 on this page. I have a clear: left on #moored that makes sure that #content-container will expand to the height of the float: left'd #content. Of course, Firefox and IE8 do it right. The weird thing though, is in IE7, it appears that #content-container is automatically expanding to contain the #secondary-content, which it shouldn't. Even weirder is when I view with IE8 with developer tools, the boundary boxes seem to show the that the #content-container is the expanding to the height of the #secondary-container, even though the background: #fff tells a different story. The background goes to where it should, and the void is now black. I've Googled a bit and came across heaps of similar float bugs, but I don't think I've found one which offers a fix yet for this circumstance. Can anyone please help me?

• git: 'log master..origin/master' not behaving as expected

  - by steve jaffe

  I'm trying to compare my copy of 'master' to that on the remote repository which it tracks. I thought that the following command would work, and often it seems to. However, sometimes it produces nothing and yet I know that the remote branch has many changes, which I can confirm by doing a pull. git log master..origin/master Can anyone explain this behavior and tell me what command I should be using to determine the changes between local and remote? [Another piece of data: I've had it happen that 'git log master..origin/master' produces nothing. Then I do a pull. The pull fails because I have a working copy of some file. After this, 'git log master..origin/master' does show me the differences. It seems the pull has updated some local log? If so, how could I achieve this without doing (or attempting to do) a pull?]

• !(ReferenceEquals()) vs != in Entity Framework 4

  - by Eric J.

  Unless a class specifically overrides the behavior defined for Object, ReferenceEquals and == do the same thing... compare references. In property setters, I have commonly used the pattern private MyType myProperty; public MyType MyProperty { set { if (myProperty != value) { myProperty = value; // Do stuff like NotifyPropertyChanged } } } However, in code generated by Entity Framework, the if statement is replaced by if (!ReferenceEquals(myProperty, value)) Using ReferenceEquals is more explicit (as I guess not all C# programmers know that == does the same thing if not overridden). Is there any difference that's escaping me between the two if-variants? Are they perhaps accounting for the possibility that POCO designers may have overridden ==? In short, if I have not overridden ==, am I save using != instead of ReferencEquals()?

• displaying keyboard raises memory... but it never comes down iPhone

  - by Joshep Freeman

  Hello again. I encountered a weird behavior in memory just by displaying the default keyboard. I've just created a project with an .xib file for testing purposes. This .xib file has an UITextField element in it and it's connected in the .h via: @property(nonatomic, retain) IBOutlet UITextField *sometext; The .m has no changes but: - (void)viewDidAppear:(BOOL)animated { [someText becomeFirstResponder]; } As you see it's very very simple. The problem is that once the keyboard is shown, the memory allocated for it NEVER goes down. I've tested this scenario in another project with the only difference of having two .xib files. Standar pushViewController and popViewController calls are made. Instruments show an increase of 600kb in memory allocations [which are a lot more in the actual iPhone device]. All in all, hehehe. My question is: How do I release the memory allocated for the keyboard?.

• UITableViewCellStyleDefault image size

  - by Rob Bonner

  Hello all, I am getting some odd behavior from stock table cells, or maybe not odd, maybe I am making some assumptions. I create the cells as follows: cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; Then I assign an image to the default imageView property. My image usually comes in from a user, so it might be larger than the default size. To take care of this I: [cell.imageView setContentMode:UIViewContentModeScaleAspectFit]; which I expected to scale the image for me within the control, but in reality, the images are all over the map. So, is there a proper way to constrain the image in stock cell types? Thanks in advance!

• Copying files from a Rails plugin into the application upon plugin install

  - by Lou Z.

  When someone installs this plugin, I would like a file to be copied into the config/initializers directory of the app. I could do this in install.rb by copying a template file that resides somewhere in the plugin. Another option would be to require the user to run a generator after install. I know rspec-rails makes you run a generator after you install it, is that the recommended behavior? And is there anything wrong with copying files into the application in install.rb? Thanks! Lou

• Changing view size when orientation changes

  - by Eyal Redler

  I want my UIView subclass to behave so that when it is fitted in portrait orientation is has a certain size and another size when fitted in landscape mode. Is it possible to have the view indicate to the view controller that's resizing it when the orientation changes that it has this "ideal size"? To clarify, I'm confident that this is not something that can be done with the autoresizing mask. I also thought that sizeThatFits: would be what I need but I didn't see it get called when the orientation changed. I'm also aware that I can get this done by overriding layoutSubviews of the superview (or maybe some other method of the view controller but I would like to have this behavior embedded in the view to facilitate reuse.

• java: decoding URI query string

  - by Jason S

  I need to decode a URI that contains a query string; expected input/output behavior is something like the following: abstract class URIParser { /** example input: * something?alias=pos&FirstName=Foo+A%26B%3DC&LastName=Bar */ URIParser(String input) { ... } /** should return "something" for the example input */ public String getPath(); /** should return a map * {alias: "pos", FirstName: "Foo+A&B=C", LastName: "Bar"} */ public Map<String,String> getQuery(); } I've tried using java.net.URI, but it seems to decode the query string so in the above example I'm left with "alias=pos&FirstName=Foo+A&B=C&LastName=Bar" so there is ambiguity whether a "&" is a query separator or is a character in a query component. edit: just tried URI.getRawQuery() and it doesn't do the encoding, so I can split the query string with a "&", but then what do I do? Any suggestions?

• How to treat an instance variable as an instance of another type in C#

  - by Ben Aston

  I have a simple inheritance heirarchy with MyType2 inheriting from MyType1. I have an instance of MyType1, arg, passed in as an argument to a method. If arg is an instance of MyType2, then I'd like to perform some logic, transforming the instance. My code looks something like the code below. Having to create a new local variable b feels inelegant - is there a way of achieving the same behavior without the additional local variable? public MyType1 MyMethod(MyType1 arg) { if(arg is MyType2) { MyType2 b = arg as MyType2; //use b (which modifies "arg" as "b" is a reference to it)... } return arg; }

• Multiple rows with a single INSERT in SQLServer 2008

  - by Todd

  I am testing the speed of inserting multiple rows with a single INSERT statement. For example: INSERT INTO [MyTable] VALUES (5, 'dog'), (6, 'cat'), (3, 'fish) This is very fast until I pass 50 rows on a single statement, then the speed drops significantly. Inserting 10000 rows with batches of 50 take 0.9 seconds. Inserting 10000 rows with batches of 51 take 5.7 seconds. My question has two parts: Why is there such a hard performance drop at 50? Can I rely on this behavior and code my application to never send batches larger than 50? My tests were done in c++ and ADO.

• How Moles Isolation framework is implemented?

  - by Buu Nguyen

  Moles is an isolation framework created by Microsoft. A cool feature of Moles is that it can "mock" static/non-virtual methods and sealed classes (which is not possible with frameworks like Moq). Below is the quick demonstration of what Moles can do: Assert.AreNotEqual(new DateTime(2012, 1, 1), DateTime.Now); // MDateTime is part of Moles; the below will "override" DateTime.Now's behavior MDateTime.NowGet = () => new DateTime(2012, 1, 1); Assert.AreEqual(new DateTime(2012, 1, 1), DateTime.Now); Seems like Moles is able to modify the CIL body of things like DateTime.Now at runtime. Since Moles isn't open-source, I'm curious to know which mechanism Moles uses in order to modify methods' CIL at runtime. Can anyone shed any light?

• Recursive mocking with Rhino-Mocks

  - by jaspernygaard

  Hi I'm trying to unittest several MVP implementations and can't quite figure out the best way to mock the view. I'll try to boil it down. The view IView consists e.g. of a property of type IControl. interface IView { IControl Control1 { get; } IControl Control2 { get; } } interface IControl { bool Enabled { get; set; } object Value { get; set; } } My question is whether there's a simple way to setup the property behavior for Enabled and Value on the IControl interface members on the IView interface - like recursive mocking a guess. I would rather not setup expectations for all my properties on the view (quite a few on each view). Thanks in advance

• What's the best BDD framework for working with ASP.NET MVC 2 + C# 4?

  - by Soul_Master

  I just heard about BDD when I watch video of Scott Guthrie in Sweden. One of listener asked question to Scott about How VS2010 and ASP.NET MVC do to support BDD. After that, I search about BDD (Behavior Driven Development) that focus on specification more than unit testing when compares with TDD (Test Driven Development). I found some framework that work with Ruby and Java. But I do not any famous framework for .NET. Please suggest me about BDD framework and summary PROs/CONs of it. PS. Suggested BDD framework must work great on .NET 4, C# 4.0 and ASP.NET MVC 2. Thanks,

• How to extract hhp file from a chm file

  - by Sam

  Hi, I have an A.chm file for my windows application which runs as expected. When I decompile it using HTML workshop I get set of html files, .hhc file, .hhk file. When I compile another file B.chm from these extracted files without changing any of the files.((I want to add more html contents to this file but looks like I am losing some information after decompiling)) The output file I get is 72K where as the original file was 75K. B.chm's contents look all file when viewed in the chm viewer but the behavior is lost when when used with the application. After reading around I found that if .hhp can be extracted from a .chm file then it can be re-constructed as it is without losing any mapping or aliases. Is that true? How can I extract .hhp file from a .chm file? Thanks, Sam

• Unable to encode to iso-8859-1 encoding for some chars using Perl Encode module

  - by ppant

  I have a HTML string in ISO-8859-1 encoding. I need to pass this string to HTML:Entities::decode_entities() for converting some of the HTML ASCII codes to respective chars. To so i am using a module HTML::Parser::Entities 3.65 but after decode_entities() operation my whole string changes to utf-8 string. This behavior seems fine as the documentation of the HTML::Parse. As i need this string back in ISO-8859-1 format for further processing so i have used Encode::encode("iso-8859-1",$str) to change the string back to ISO-8859-1 encoding. My results are fine excepts for some chars, a question mark is coming instead. One example is single quote ' ASCII code (’) Can anybody help me if there any limitation of Encode module? Any other pointer will also be helpful to solve the problem. Thanks

• elegant way to make directory recursively in Python?

  - by user248237

  I would like to make a directory in a "recursive" way, i.e. have a function make_directory() that behaves as follows: make_directory("a/b/c/d/") should create directory a, then child b, then c, then d. If any of the parent directories exist it should not make them. E.g. if "a" exists, then b should be a subdir of that, and then c should be made inside b, etc. how can I do this in python? os.mkdir does not have this behavior.

• C# WCF client configuration for X509 secured web service over https

  - by Kam

  Hi guys I been pulling my hair out for the past few days trying to connect to a web service using .Net 3.5 and WCF (have also tried using WSE 3.0) without much luck. The web service is hosted by a 3rd party and we can access via https. They also make use of X509 certificates for security, to sign the message. I've been given some basic info and am able to connect and test the service using SOAP UI 3.5 without any problems, so we know that this is not the issue. Just trying to get it done in code! I've added the X509 certificate into the certificate store using the mmc snap-in, and using tracing and logging i can see that the message is being signed, just unable to see which part i have got wrong. Any healp GREATLY appreciated :) I've been given an offline WSDL file, which I have imported in as a service reference is VS 2008. My calling code looks like so, simple enough: ServicePointManager.ServerCertificateValidationCallback = delegate(object sender,X509Certificate certificate,X509Chain chain, SslPolicyErrors sslErrors) { return true; }; GatewayClient gateway = new GatewayClient(); CheckStatusResponse response = gateway.CheckLineStatus(); And my config looks like so: <basicHttpBinding> <binding name="Gateway_1.0" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="8192" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <security mode="TransportWithMessageCredential"> <transport clientCredentialType="None" proxyCredentialType="None" realm="" /> <message clientCredentialType="Certificate" algorithmSuite="Default" /> </security> </binding> </basicHttpBinding> <customBinding> <binding name="Gateway_1"> <security authenticationMode="CertificateOverTransport" includeTimestamp="true" messageProtectionOrder="SignBeforeEncrypt"> <localClientSettings maxClockSkew="12:00:00" replayWindow="12:00:00" sessionKeyRolloverInterval="12:00:00" timestampValidityDuration="12:00:00" /> <localServiceSettings maxClockSkew="12:00:00" sessionKeyRolloverInterval="12:00:00" timestampValidityDuration="12:00:00" /> <secureConversationBootstrap /> </security> <textMessageEncoding messageVersion="Soap11" /> <sslStreamSecurity requireClientCertificate="true" /> <httpsTransport hostNameComparisonMode="WeakWildcard" /> </binding> </customBinding> <wsHttpBinding> <binding name="Gateway_1" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true" allowCookies="false"> <security mode="TransportWithMessageCredential"> <message clientCredentialType="Certificate" negotiateServiceCredential="false" establishSecurityContext="true" /> </security> </binding> </wsHttpBinding> </bindings> <client> <endpoint address="https://XXX.XX.XXX.XX/SOAP" behaviorConfiguration="ClientCertificateBehavior" binding="wsHttpBinding" bindingConfiguration="Gateway_1" contract="B2BService.Gateway" name="Gateway_1_HTTPSPort"> <identity> <dns value="ext.test.com" /> </identity> </endpoint> </client> <behaviors> <endpointBehaviors> <behavior name="ClientCertificateBehavior"> <clientCredentials> <clientCertificate findValue="mycertificate.com" storeLocation="CurrentUser" storeName="Root" x509FindType="FindBySubjectName" /> <serviceCertificate> <authentication certificateValidationMode="PeerOrChainTrust" /> </serviceCertificate> </clientCredentials> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> Regardless of which config I use, the code fails for one reason or another, causing internal server errors, Error processing message for security, Undefined 'badEncoding' resource property, or expected http URI given https, and a few other! Been going round and round a bit, and I am sure it is very simple once the cofig is set :( I'm sure I've missed loads out, let me know if seeing the SOAP UI generated envelope and the currect WCF generated envelope will help. many thanks.

• Why is Standard Input is not displayed as I type in Mac OS X Terminal application?

  - by BryanWheelock

  I'm confused by some behavior of my Mac OS X Terminal and my Django manage.py shell and pdb. When I start a new terminal, the Standard Input is displayed as I type. However, if there is an error, suddenly Standard Input does not appear on the screen. This error continues until I shut down that terminal window. The Input is still being captured as I can see the Standard Output. E.g. in pdb.set_trace() I can 'l' to display where I'm at in the code. However, the 'l' will not be displayed, just an empty prompt. This makes it hard to debug because I can't determine what I'm typing in. What could be going wrong and what can I do to fix it?
