  • How to solve concurrency problems in ASP.NET Windows-Workflow and ActiveRecord/NHibernate?

    - by Famous Nerd
    I have found that ActiveRecord uses the Session-Scope object within the ASP.NET application and that if the web-site is read-write we can have a tug-o-war between the Workflow's own Data-Access SessionScope and that of the ASP.NET site. I would really like to have the WindowsWorkflow Runtime use the same object session as the web-site however, they have different lifetimes. Sometimes, a web-request may save a very simple piece of data which would execute quickly however, if the web-site kicks off a workflow process.. how can that workflow make data-modifications while still allowing the Appliaction_EndRequest to dispose the ASP.NET SessionScope ... it's like ownership of the SessionScope should be shared between the workflow runtime and the ASP.NET website. Manual Workflow Scheduler may be the Savior... if a workflow is synchronous and merely uses CallExternalMethod to interact with the Host then we could constrain all the data-access to the host.. then the sessionScope can exist once. This however, won't solve the problem of a delay activity... if this delay fires, we could need to update data... in this case we'd need an isolated Session Scope and concurrency may arise. This however, differs from SharePoint workflows where it seems that the SharePoint workflow can save data from the web and the workflow and that concurrency is handled through other means. Can anyone offer any suggestions on how to allow the workflow to manage data and play nice with ASP.NET web sites?

  • Rails named_scope across multiple tables

    - by wakiki
    I'm trying to tidy up my code by using named_scopes in Rails 2.3.x but where I'm struggling with the has_many :through associations. I'm wondering if I'm putting the scopes in the wrong place... Here's some pseudo code below. The problem is that the :accepted named scope is replicated twice... I could of course call :accepted something different but these are the statuses on the table and it seems wrong to call them something different. Can anyone shed light on whether I'm doing the following correctly or not? I know Rails 3 is out but it's still in beta and it's a big project I'm doing so I can't use it in production yet. class Person < ActiveRecord::Base has_many :connections has_many :contacts, :through => :connections named_scope :accepted, :conditions => ["connections.status = ?", Connection::ACCEPTED] # the :accepted named_scope is duplicated named_scope :accepted, :conditions => ["memberships.status = ?", Membership::ACCEPTED] end class Group < ActiveRecord::Base has_many :memberships has_many :members, :through => :memberships end class Connection < ActiveRecord::Base belongs_to :person belongs_to :contact, :class_name => "Person", :foreign_key => "contact_id" end class Membership < ActiveRecord::Base belongs_to :person belongs_to :group end I'm trying to run something like person.contacts.accepted and group.members.accepted which are two different things. Shouldn't the named_scopes be in the Membership and Connection classes? One solution is to just call the two different named scope something different in the Person class or even to create separate associations (ie. has_many :accepted_members and has_many :accepted_contacts) but it seems hackish and in reality I have many more than just accepted (ie. banned members, ignored connections, pending, requested etc etc)

  • Is there a default way to get hold of an internal property in jQueryUi widget?

    - by prodigitalson
    Im using an existing widget from the jquery-ui labs call selectmenu. It has callback options for the events close and open. The problem is i need in these event to animate a node that is part of the widget but not what its connected to. In order to do this i need access to this node. for example if i were to actually modify the widget code itself: // ... other methods/properties "open" : function(event){ // ... the original logic // this is my animation $(this.list).slideUp('slow'); // this is the orginal call to _trigger this._trigger('open', event, $this._uiHash()); }, // ... other methods/properties However when in the scope of the event handler i attach this is the orginal element i called the widget on. I need the widget instance or specifically the widget instance's list property. $('select#custom').selectmenu({ 'open': function(){ // in this scope `this` is an HTMLSelectElement not the ui widget } }); Whats the best way to go about getting the list property from the widget?

  • Declaring an enum within a class

    - by bporter
    In the following code snippet, the Color enum is declared within the Car class in order to limit the scope of the enum and to try not to "pollute" the global namespace. class Car { public: enum Color { RED, BLUE, WHITE }; void SetColor( Car::Color color ) { _color = color; } Car::Color GetColor() const { return _color; } private: Car::Color _color; }; (1) Is this a good way to limit the scope of the Color enum? Or, should I declare it outside of the Car class, but possibly within its own namespace or struct? I just came across this article today, which advocates the latter and discusses some nice points about enums: http://gamesfromwithin.com/stupid-c-tricks-2-better-enums. (2) In this example, when working within the class, is it best to code the enum as Car::Color, or would just Color suffice? (I assume the former is better, just in case there is another Color enum declared in the global namespace. That way, at least, we are explicit about the enum to we are referring.) Thanks in advance for any input on this.

  • python interactive mode module import issue

    - by Jeff
    I believe I have what would be called a scope issue, perhaps name space. Not too sure I'm new to python. I'm trying to make a module that will search through a list using regular expressions. I'm sure there is a better way of doing it but this error that I'm getting is bugging me and I want to understand why. here's my code: class relist(list): def __init__(self, l): list.__init__(self, l) def __getitem__(self, rexp): r = re.compile(rexp) res = filter(r.match, self) return res if __name__ == '__main__': import re listl = [x+y for x in 'test string' for y in 'another string for testing'] print(listl) test = relist(listl) print('----------------------------------') print(test['[s.]']) When I run this code through the command line it works the way I expect it to; however when I run it through python interactive mode I get the error >>> test['[s.]'] Traceback (most recent call last): File "<stdin>", line 1, in <module> File "relist.py", line 8, in __getitem__ r = re.compile(rexp) NameError: global name 're' is not defined While in the interactive mode I do import re and I am able to use the re functions, but for some reason when I'm trying to execute the module it doesn't work. Do I need to import re into the scope of the class? I wouldn't think so because doesn't python search through other scopes if it's not found in the current one? I appreciate your help, and if there is a better way of doing this search I would be interested in knowing. Thanks

  • Session scoped bean as class attribute of Spring MVC Controller

    - by Sotirios Delimanolis
    I have a User class: @Component @Scope("session") public class User { private String username; } And a Controller class: @Controller public class UserManager { @Autowired private User user; @ModelAttribute("user") private User createUser() { return user; } @RequestMapping(value = "/user") public String getUser(HttpServletRequest request) { Random r = new Random(); user.setUsername(new Double(r.nextDouble()).toString()); request.getSession().invalidate(); request.getSession(true); return "user"; } } I invalidate the session so that the next time i got to /users, I get another user. I'm expecting a different user because of user's session scope, but I get the same user. I checked in debug mode and it is the same object id in memory. My bean is declared as so: <bean id="user" class="org.synchronica.domain.User"> <aop:scoped-proxy/> </bean> I'm new to spring, so I'm obviously doing something wrong. I want one instance of User for each session. How?

  • Pro/con of using Angular directives for complex form validation/ GUI manipulation

    - by tengen
    I am building a new SPA front end to replace an existing enterprise's legacy hodgepodge of systems that are outdated and in need of updating. I am new to angular, and wanted to see if the community could give me some perspective. I'll state my problem, and then ask my question. I have to generate several series of check boxes based on data from a .js include, with data like this: $scope.fieldMappings.investmentObjectiveMap = [ {'id':"CAPITAL PRESERVATION", 'name':"Capital Preservation"}, {'id':"STABLE", 'name':"Moderate"}, {'id':"BALANCED", 'name':"Moderate Growth"}, // etc {'id':"NONE", 'name':"None"} ]; The checkboxes are created using an ng-repeat, like this: <div ng-repeat="investmentObjective in fieldMappings.investmentObjectiveMap"> ... </div> However, I needed the values represented by the checkboxes to map to a different model (not just 2-way-bound to the fieldmappings object). To accomplish this, I created a directive, which accepts a destination array destarray which is eventually mapped to the model. I also know I need to handle some very specific gui controls, such as unchecking "None" if anything else gets checked, or checking "None" if everything else gets unchecked. Also, "None" won't be an option in every group of checkboxes, so the directive needs to be generic enough to accept a validation function that can fiddle with the checked state of the checkbox group's inputs based on what's already clicked, but smart enough not to break if there is no option called "NONE". I started to do that by adding an ng-click which invoked a function in the controller, but in looking around Stack Overflow, I read people saying that its bad to put DOM manipulation code inside your controller - it should go in directives. So do I need another directive? So far: (html): <input my-checkbox-group type="checkbox" fieldobj="investmentObjective" ng-click="validationfunc()" validationfunc="clearOnNone()" destarray="investor.investmentObjective" /> Directive code: .directive("myCheckboxGroup", function () { return { restrict: "A", scope: { destarray: "=", // the source of all the checkbox values fieldobj: "=", // the array the values came from validationfunc: "&" // the function to be called for validation (optional) }, link: function (scope, elem, attrs) { if (scope.destarray.indexOf(scope.fieldobj.id) !== -1) { elem[0].checked = true; } elem.bind('click', function () { var index = scope.destarray.indexOf(scope.fieldobj.id); if (elem[0].checked) { if (index === -1) { scope.destarray.push(scope.fieldobj.id); } } else { if (index !== -1) { scope.destarray.splice(index, 1); } } }); } }; }) .js controller snippet: .controller( 'SuitabilityCtrl', ['$scope', function ( $scope ) { $scope.clearOnNone = function() { // naughty jQuery DOM manipulation code that // looks at checkboxes and checks/unchecks as needed }; The above code is done and works fine, except the naughty jquery code in clearOnNone(), which is why I wrote this question. And here is my question: after ALL this, I think to myself - I could be done already if I just manually handled all this GUI logic and validation junk with jQuery written in my controller. At what point does it become foolish to write these complicated directives that future developers will have to puzzle over more than if I had just written jQuery code that 99% of us would understand with a glance? How do other developers draw the line? I see this all over Stack Overflow. For example, this question seems like it could be answered with a dozen lines of straightforward jQuery, yet he has opted to do it the angular way, with a directive and a partial... it seems like a lot of work for a simple problem. Specifically, I suppose I would like to know: how SHOULD I be writing the code that checks whether "None" has been selected (if it exists as an option in this group of checkboxes), and then check/uncheck the other boxes accordingly? A more complex directive? I can't believe I'm the only developer that is having to implement code that is more complex than needed just to satisfy an opinionated framework.

  • iPack -The iOS Application Packager

    - by user13277780
    iOS applications are distributed in .ipa archive files. These files are regular zip files which contain application resources and executable-s. To protect them from unauthorized modifications and to provide identification of their sources, the content of the archives is signed. The signature is included in the application executable of an.ipa archive and protects the executable file itself and the associated resource files. Apple provides native Mac OS tools for signing iOS executable-s (which are actually generic Mach-O code signing tools), but these tools are not generally available on other platforms. To provide a multi-platform development environment for JavaFX based iOS applications, we ported iOS signing and packaging to Java and created a dedicated ipack tool for it. The iPack tool can be used as a last step of creating .ipa package on various operating systems. Prototype has been tested by creating a final distributable for JavaFX application that runs on iPad, all done on Windows 7. Source Code The source code of iPac tool is in OpenJFX project repository. You can find it in: <openjfx root>/rt/tools/ios/Maven/ipack To build the iPack tool use: rt/tools/ios/Maven/ipack$ mvn package After building, you can run the tool: java -jar <path to ipack.jar> <arguments>  Signing keystore The tool uses a java key store to read the signing certificate and the associated private key. To prepare such keystore users can use keytool from JDK. One possible scenario is to import an existing private key and the certificate from a key store used on Mac OS: To list the content of an existing key store and identify the source alias: keytool -list -keystore <src keystore>.p12 -storetype pkcs12 -storepass <src keystore password> To create Java key store and import the private key with its certificate to the keys store: keytool -importkeystore \ -destkeystore <dst keystore> -deststorepass <dst keystore password> \ -srckeystore <src keystore>.p12 -srcstorepass <src keystore password> -srcstoretype pkcs12 \ -srcalias <src alias> -destalias <dst alias> -destkeypass <dst key password> Another scenario would be to generate a private / public key pair directly in a Java key store and create a certificate request from it. After sending the request to Apple one can then import the certificate response back to the Java key store and complete the signing certificate entry. In both scenarios the resulting alias in the Java key store will contain only a single (leaf) certificate. This can be verified with the following command: keytool -list -v -keystore <ipack keystore> -storepass <keystore password> When looking at the Certificate chain length entry, the number next to it is 1. When an executable file is signed on Mac OS, the resulting signature (in CMS format) includes the whole certificate chain up to the Apple Root CA. The ipack tool includes only the chain which is stored under the alias specified on the command line. So to have the whole chain in the signature we need to replace the single certificate entry under the alias with the corresponding full certificate chain. To do that we need first to create the chain in a separate file. It is easy to create such chain when working with certificates in Base-64 encoded PEM format. A certificate chain can be created by concatenating PEM certificates, which should form the chain, into a single file. For iOS signing we need the following certificates in our chain: Apple Root CA Apple Worldwide Developer Relations CA Our signing leaf certificate To convert a certificate from the binary DER format (.der, .cer) to PEM format: keytool -importcert -noprompt -keystore temp.ks -storepass temppwd -alias tempcert -file <certificate>.cer keytool -exportcert -keystore temp.ks -storepass temppwd -alias tempcert -rfc -file <certificate>.pem To export the signing certificate into PEM format: keytool -exportcert -keystore <ipack keystore> -storepass <keystore password> -alias <signing alias> -rfc -file SigningCert.pem After constructing a chain from AppleIncRootCertificate.pem, AppleWWDRCA.pem andSigningCert.pem, it can be imported back into the keystore with: keytool -importcert -noprompt -keystore <ipack keystore> -storepass <keystore password> -alias <signing alias> -keypass <key password> -file SigningCertChain.pem To summarize, the following example shows the full certificate chain replacement process: keytool -importcert -noprompt -keystore temp.ks -storepass temppwd -alias tempcert1 -file AppleIncRootCertificate.cer keytool -exportcert -keystore temp.ks -storepass temppwd -alias tempcert1 -rfc -file AppleIncRootCertificate.pem keytool -importcert -noprompt -keystore temp.ks -storepass temppwd -alias tempcert2 -file AppleWWDRCA.cer keytool -exportcert -keystore temp.ks -storepass temppwd -alias tempcert2 -rfc -file AppleWWDRCA.pem keytool -exportcert -keystore ipack.ks -storepass keystorepwd -alias mycert -rfc -file SigningCert.pem cat SigningCert.pem AppleWWDRCA.pem AppleIncRootCertificate.pem >SigningCertChain.pem keytool -importcert -noprompt -keystore ipack.ks -storepass keystorepwd -alias mycert -keypass keypwd -file SigningCertChain.pem keytool -list -v -keystore ipack.ks -storepass keystorepwd Usage When the ipack tool is started with no arguments it prints the following usage information: -appname MyApplication -appid com.myorg.MyApplication     Usage: ipack <archive> <signing opts> <application opts> [ <application opts> ... ] Signing options: -keystore <keystore> keystore to use for signing -storepass <password> keystore password -alias <alias> alias for the signing certificate chain and the associated private key -keypass <password> password for the private key Application options: -basedir <directory> base directory from which to derive relative paths -appdir <directory> directory with the application executable and resources -appname <file> name of the application executable -appid <id> application identifier Example: ipack MyApplication.ipa -keystore ipack.ks -storepass keystorepwd -alias mycert -keypass keypwd -basedir mysources/MyApplication/dist -appdir Payload/MyApplication.app -appname MyApplication -appid com.myorg.MyApplication

  • Variable scoping and the jQuery.getJSON() method

    - by jerome
    The jQuery.getJSON() method seems to ignore the normal rules of scoping within JavaScript. Given code such as this... someObject = { someMethod: function(){ var foo; $.getJSON('http://www.somewhere.com/some_resource', function(data){ foo = data.bar; }); alert(foo); // undefined } } someObject.someMethod(); Is there a best practice for accessing the value of the variable outside of the getJSON scope?

  • Can I access Spring session-scoped beans from application-scoped beans? How?

    - by Corvus
    I'm trying to make this 2-player web game application using Spring MVC. I have session-scoped beans Player and application-scoped bean GameList, which creates and stores Game instances and passes them to Players. On player creates a game and gets its ID from GameList and other player sends ID to GameList and gets Game instance. The Game instance has its players as attributes. Problem is that each player sees only himself instead of the other one. Example of what each player sees: First player (Alice) creates a game: Creator: Alice, Joiner: Empty Second player (Bob) joins the game: Creator: Bob, Joiner: Bob First player refreshes her browser Creator: Alice, Joiner: Alice What I want them to see is Creator: Alice, Joiner: Bob. Easy way to achieve this is saving information about players instead of references to players, but the game object needs to call methods on its player objects, so this is not a solution. I think it's because of aop:scoped-proxy of session-scoped Player bean. If I understand this, the Game object has reference to proxy, which refers to Player object of current session. Can Game instance save/access the other Player objects somehow? beans in dispatcher-servlet.xml: <bean id="userDao" class="authorization.UserDaoFakeImpl" /> <bean id="gameList" class="model.GameList" /> <bean name="/init/*" class="controller.InitController" > <property name="gameList" ref="gameList" /> <property name="game" ref="game" /> <property name="player" ref="player" /> </bean> <bean id="game" class="model.GameContainer" scope="session"> <aop:scoped-proxy/> </bean> <bean id="player" class="beans.Player" scope="session"> <aop:scoped-proxy/> </bean> methods in controller.InitController private GameList gameList; private GameContainer game; private Player player; public ModelAndView create(HttpServletRequest request, HttpServletResponse response) throws Exception { game.setGame(gameList.create(player)); return new ModelAndView("redirect:game"); } public ModelAndView join(HttpServletRequest request, HttpServletResponse response, GameId gameId) throws Exception { game.setGame(gameList.join(player, gameId.getId())); return new ModelAndView("redirect:game"); } called methods in model.gameList public Game create(Player creator) { Integer code = generateCode(); Game game = new Game(creator, code); games.put(code, game); return game; } public Game join(Player joiner, Integer code) { Game game = games.get(code); if (game!=null) { game.setJoiner(joiner); } return game; }

  • Mixed declarations and code in open source projects?

    Why is still C99 mixed declarations and code not used in open source C projects like the Linux kernel or GNOME? I really like mixed declarations and code since it makes the code more readable and prevents hard to see bugs by restricting the scope of the variables to the narrowest possible. This is recommended by Google for C++. For example, Linux requires at least GCC 3.2 and GCC 3.1 has support for C99 mixed declarations and code
