The constructor has been modified to set the Web service URL, which has to be the subscriber URL.</p><a name="toc7"><h3><font class="Heading-3">Global.asax.cs</font></h3></a><p>Global class contains two static members, subRep, a RepoSubs singleton and archRep, a RepoArchs singleton. Global restores archRep and subRep at the first request performed on the Repository application in Application_BeginRequest.</p>
<p></p>
<p>Application_BeginRequest calls restore to restore subRep and archRep.</p>
<p>restore uses RepoArchs and RepoSubs's constructors with an XmlReader to restore subRep and archRep from subscribers.xml and archives.xml.</p>
<p></p>
<p>Global class contains two methods, saveSubRep to save subRep on subscribers.xml and saveArchRep to save archRep on archives.xml. These methods call the WriteXml methods of RepoSubs and RepoArchs.</p><a name="toc8"><h3><font class="Heading-3">subcriber.aspx.cs</font></h3></a><p>The SubscriberWF class manages a form that</p>
<ul><li><p>Lists the Repository subscribers using a DataGrid</p></li>

</ul>
<p></p>
<p>The bind method binds an ArrayList to the Datagrid. This ArrayList contains SubscriberEntry objects.</p>
<p>bind populates the ArrayList from RepoSubs.subscribers.</p>
<p>bind is called by Page_Load, subscriberDB_unsubscribe, Form1_subscribe, Form1_unsubscribe, Form1_force, Form1_refresh.</p>
<p></p>
<p>subscriber.aspx provides two buttons to remove subscribers Unsubscribe and Force and a button to refresh the Datagrid, refresh. When the user clicks one of these buttons, Form1_subscribe, Form1_unsubscribe, Form1_force or Form1_refresh is invoked.</p>
<p>Form1_subscribe invokes RepoSubs.subscribe.</p>
<p>Form1_unsubscribe and Form1_force invoke RepoSubs.unsubscribe.</p>
<p></p>
<p>Force allows removing a PageBox that doesn't exist (anymore) whereas Unsubscribe keeps the subscriber in "pending unsubscribe" state. In that state the subscriber doesn't receive new archives.</p>
<p></p>
<p>The Datagrid rows have also two buttons, unsub and force.</p>
<p>In InitializeComponent we added subscriberDB_unsubscribe to the Datagrid's ItemCommand as DataGridCommandEventHandler. When the user clicks either on unsub or force buttons, subscriberDB_unsubscribe is called. subscriberDB_unsubscribe calls RepoSubs.unsubscribe.</p><a name="toc9"><h3><font class="Heading-3">publisher.aspx.cs</font></h3></a><p>The publisher class manages a form that</p>
<ul><li><p>Lists the uploaded presentations and batchs using a Datagrid.</p></li>
<li><p>Allows uploading and removing presentations and batchs.</p></li>
</ul>
<p></p>
<p>If you put authentication in place then only publishers and administrators can use that form and a publisher can only see the presentations and batchs that she or he has published.</p>
<p>A user is a publisher if its user id is defined in RepoArchs.publishers.</p>
<p>A user is an administrator if its user id is defined in RepoArchs.administrators.</p>
<p>RepoArchs restores publishers and administrators from authorization.xml. Here is an example of authorization.xml:</p>
<p></p>
<table class="cuckoo-table"><tr name="tr0"><td class="cuckoo-td" valign="top"><p><authorization></p><p>  <administrators></p><p>    <user>admin</user></p><p>  </administrators></p><p>  <publishers></p><p>    <user>publisher1</user></p><p>    <user>publisher2</user></p><p>  </publishers>  </p><p></authorization></p></td></tr></table>
<p></p>
<p>authorization.xml handles role authorizations. Authentication is defined in web.config. By default we use Form based authentication with login-form.aspx:</p>
<p></p>
<table class="cuckoo-table"><tr name="tr0"><td class="cuckoo-td" valign="top"><p>    <authentication mode="Forms"></p><p>          <forms loginUrl="login-form.aspx"></p><p>              <credentials passwordFormat="Clear"></p><p>                 <user name="admin" password="admin" /></p><p>                 <user name="subscriber1" password="subscriber" /></p><p>                 <user name="subscriber2" password="subscriber" /></p><p>                 <user name="publisher1" password="publisher" /></p><p>                 <user name="publisher2" password="publisher" /></p><p>              </credentials></p><p>          </forms></p><p>    </authentication></p><p>    <authorization></p><p>          <deny users="?" /></p><p>    </authorization></p></td></tr></table>
<p></p>
<p>It is very important to define the <authorization> element and to forbid unauthenticated access to the Repository application.</p>
<p></p>
<p>When authentication is in place:</p>
<ol><li><p>In case of publication, publisher registers the user id as the owner of the presentation</p></li>
<li><p>A user B cannot publish a presentation with the same name as a presentation previously published by a user A</p></li>
<li><p>update.aspx displays the owner of deployed archives</p></li>
</ol>
<p></p>
<p></p>
<p>The bind method binds an ArrayList to the Datagrid. This ArrayList contains PublisherEntry objects.</p>
<p>bind populates the ArrayList from RepoArchs.archives and RepoArchs.docs.</p>
<p>bind is called by Page_Load, archUpload, refresh, archiveDB_delete.</p>
<p></p>
<p>publisher.aspx provides a button to upload archives Upload and a button to refresh the Datagrid, Refresh. When the user clicks one of these buttons, archUpload or refresh is invoked.</p>
<p></p>
<p>archUpload processes POST method upload as defined in RFC 1867. The upload code is quite simple:</p>
<p></p>
<table class="cuckoo-table"><tr name="tr0"><td class="cuckoo-td" valign="top"><p>string arch = archFile.PostedFile.FileName;</p><p>int pos = arch.LastIndexOf("\\");</p><p>arch = arch.Substring(pos + 1);</p><p>if (!Directory.Exists(Global.archRep.downloadPath))</p><p>	Directory.CreateDirectory(Global.archRep.downloadPath);</p><p>archFile.PostedFile.SaveAs(Global.archRep.downloadPath + arch);</p><p>LabStatus.Text = Global.archRep.add(arch, owner, docURL.Value);</p><p>bind();</p></td></tr></table>
<p></p>
<p>archUpload saves the uploaded file in downloadPath, which is Repository-Directory\..\download as defined in Global.asax.cs with a Repository  name which is the same as the uploaded file (arch). Then it calls RepoArchs.add to add the archive to RepoArchs.archives and trigger the deployment of the presentation/batch on subscribers.</p>
<p></p>
<p>Beside the presentation location, publisher.aspx allows specifying the URL of the presentation documentation. archUpload retrieves it in docURL.value. </p>
<p></p>
<p>The Datagrid rows have also two buttons, Delete and Force.</p>
<p>In InitializeComponent we added archiveDB_delete to the Datagrid's ItemCommand as DataGridCommandEventHandler. When the user clicks either on Delete or Force buttons, archiveDB_delete is called. archiveDB_delete calls RepoArchs.delete.</p>
<p></p>
<p>In both cases publisher send an undeploy(<font class="test-style2">presentation</font><font class="Normal">) to all subscribers and removes the presentation file from the repository. If the undeploy succeeds, the presentation is removed from the archive list of the subscriber.</font></p>
<p></p>
<p>If the undeploy fails for one subscriber:</p>
<ul><li><p>The presentation is removed from the archive list of the subscriber in case of Force</p></li>
<li><p>The presentation is kept in the archive list of the subscriber in case of Delete</p></li>
</ul><a name="toc10"><h3><font class="Heading-3">asubscriber.aspx.cs</font></h3></a><p>The asubscriber class is very similar to subscriber.aspx.cs. It manages a form that</p>

</ul>
<p></p>
<p>The bind method binds an ArrayList to the Datagrid. This ArrayList contains SubscriberEntry objects.</p>
<p>bind populates the ArrayList from RepoSubs.subscribers.</p>
<p>bind is called by Page_Load, subscriberDB_handle, Form1_subscribe, Form1_unsubscribe, Form1_force, Form1_refresh.</p>
<p></p>
<p>asubscriber.aspx provides two buttons to remove subscribers Unsubscribe and Force and a button to refresh the Datagrid, refresh. When the user clicks one of these buttons, Form1_subscribe, Form1_unsubscribe, Form1_force or Form1_refresh is invoked.</p>
<p>Form1_subscribe invokes RepoSubs.asubscribe.</p>
<p>Form1_unsubscribe and Form1_force invoke RepoSubs.unasubscribe.</p>
<p></p>
<p>Force allows removing a PageBox that doesn't exist (anymore) whereas Unsubscribe keeps the subscriber in "pending unsubscribe" state. In that state the subscriber doesn't receive new archives.</p>
<p></p>
<p>The Datagrid rows have also two buttons, unsub and force.</p>
<p>In InitializeComponent we added subscriberDB_handle to the Datagrid's ItemCommand as DataGridCommandEventHandler. When the user clicks either on unsub or force buttons, subscriberDB_handle is called. subscriberDB_handle calls RepoSubs.unasubscribe.</p>
<p></p>
<p>The Datagrid rows also contain a link to the aselect page. This link is created in asubscriber.aspx by</p>
<p><asp:HyperLinkColumn HeaderText=" " ItemStyle-Width="7%" Text="Archives" DataNavigateUrlField="PageBox" DataNavigateUrlFormatString="aselect.aspx?subscriber={0}"/></p>
<p>When you click on such a link, aselect is invoked in GET mode with a subscriber parameter containing the URL of the PageBox Web service.</p><a name="toc11"><h3><font class="Heading-3">aselect.aspx.cs</font></h3></a><p>aselect.aspx.cs manages a form that:</p>
<ul><li><p>Lists the repository archives with a checkbox checked when the archive is deployed on this Archive subscriber</p></li>
<li><p>Allows adding or removing archives on the subscription</p></li>
</ul>
<p></p>
<p>The form operates by delta:</p>
<ul><li><p>If you check a checkbox the corresponding archive is deployed</p></li>
<li><p>If you uncheck a checkbox the corresponding archive is undeployed</p></li>
<li><p>You can make multiple changes before submitting the changes</p></li>
</ul>
<p></p>
<p>To support this feature we use a MultiGrid class that extends DataGrid.</p>
<p>MultiGrid is based on the <a href="http://msdn.microsoft.com/msdnmag/issues/02/01/cutting/cutting0201.asp">article</a><font class="Normal"> of Dino Esposito published in the MSDN issue of January 2002.</font></p>
<p>It includes two changes:</p>
<ol><li><p>The BindName method of SelectColumnTemplate sets the checkbox after the archive status (deployed/not deployed)</p></li>
<li><p>The SelectedItems property of MultiGrid returns an array of SelectedEntry objects. A SelectedEntry object contains the checkbox status and the row number</p></li>
</ol>
<p>
</p>
<p>The bind method binds an ArrayList to the MultiGrid. This ArrayList contains SelectorEntry objects.</p>
<p>bind populates the ArrayList from RepoArchs.archives and RepoArchs.docs.</p>
<p>bind is called by Page_Load and Form1_refresh.</p>
<p></p>
<p>Form1_refresh reads SelectedItems, enumerates the archives and adds or remove archives on the subscription list accordingly.</p><a name="toc12"><h3><font class="Heading-3">download.aspx.cs</font></h3></a><p>download.aspx allows downloading presentations from Repositories without subscription:</p>
<p>When the presentation is updated, it is not deployed on the download site.</p>
<p>The download site doesn't need a PageBox.</p>
<p></p>
<p>The download class manages a form that lists the uploaded presentations and batches using a Datagrid.</p>
<p>It implements one method, Page_Load that populates an ArrayList from RepoArchs.archives and RepoArchs.docs and binds it to the Datagrid. This ArrayList contains DownloadEntry objects.</p>
<p>A DownloadEntry contains both the presentation name (Archive) and download URL (ArchiveURL).</p>
<p></p>

<p>The audit class implements two methods, clear and include.</p>
<p>Both methods first check that the user is an administrator.</p>
<p>clear removes the log.rep file.</p>
<p>include calls Response.WriteFile("log.rep")</p>
<p></p>
<p>clear is invoked through the Clear button.</p>
<p>include is invoked by <% include(); %>.</p><a name="toc15"><h3><font class="Heading-3">Retry.asmx</font></h3></a><p>If it is properly configured, RepoCleanup calls the Retry.asmx every 30 minutes to retry pending deploys and undeploys. With this mechanism PageBox for .NET can cope with transient conditions such as Pagebox server reboot.</p>
<p></p>
<p>Because Retry.asmx is implemented as a Web Service a single RepoCleanup can monitor a set of Repositories on different machines.</p>
<p></p>
<p>Retry.asmx invokes the cleanup method of RepoSubs.cs.</p>
<p></p>
<p>Form based authentication, which is the preferred authentication scheme for the Repository, is not suitable for Web services. Therefore Retry.asmx is installed on a WebServices subdirectory of the repository.</p>
<p>WebServices contains a specific web.config that disables form-based authentication:</p>
<p></p>
<table class="cuckoo-table"><tr name="tr0"><td class="cuckoo-td" valign="top"><p><configuration>   </p><p>  <system.web></p><p>    <authorization></p><p>       <allow users="?" /></p><p>    </authorization></p><p>  </system.web></p><p></configuration></p></td></tr></table>
<p></p>
<p class="FormGet">Retry.asmx implements a custom authentication and authorization mechanism consistent with the rest of the Repository: only Repository administrators are allowed to issue cleanup requests. This mechanism is quite simple.</p>

<p></p>
<ol><li><p>Retry.asmx has a single method, Cleanup whose parameters are the user name and password to check</p></li>
<li><p>Cleanup uses  FormsAuthentication.Authenticate to check if the user is defined and if its password is correct</p></li>

<li><p>If the user credentials are OK, Cleanup calls the RepoSub's cleanup method</p></li>
</ol><a name="toc16"><h3><font class="Heading-3">RepoQuery.asmx</font></h3></a><p>RepoQuery has two methods:</p>
<ol><li><p>GetSubscribers, the single method of the RepoQuery Web service. GetSubscribers returns an array that contains the URL of all subscribers and archive subscribers to a presentation but the requesting subscriber. GetSubscriber is called by the Query Web service of PageBox. GetSubscribers invokes the populate method to retrieve subscribers or archive subscribers.</p></li>
<li><p>populate enumerates the subscribers or archive subscribers and select the subscribers to the presentation</p></li>
</ol><a name="toc17"><h2><font class="Heading-2">PageBox</font></h2></a><a name="toc18"><h3><font class="Heading-3">PbArch.cs</font></h3></a><p>The PbArch class describes presentations and batchs deployed on a PageBox.</p>

<li><p>inflate. inflate contains InstallCommand objects and describes supported extensions and how to install a presentation with a given extension</p></li>
<li><p>remove. remove also contains InstallCommand objects and describes how to uninstall a presentation with a given extension</p></li>
</ul>
<p></p>
<p>The InstallCommand class has three fields:</p>
<ul><li><p>cmd</p></li>
<li><p>paramPrefix</p></li>
<li><p>useShell</p></li>
</ul>
<p></p>
<p>To process a command, PbArch uses a ProcessStartInfo object:</p>
<p></p>
<table class="cuckoo-table"><tr name="tr0"><td class="cuckoo-td" valign="top"><p>ProcessStartInfo psi = new ProcessStartInfo();</p><p>psi.FileName = ic.cmd;</p><p>psi.UseShellExecute = ic.useShell;</p><p>psi.Arguments = ic.paramPrefix + Global.path + "\\" + a;</p><p>Process p = Process.Start(psi);</p></td></tr></table>
<p></p>
<p>A command has a mandatory parameter, which is the archive path.</p>
<p>The parameter string is built like this:</p>
<p></p>
<table class="cuckoo-table"><tr name="tr0"><td class="cuckoo-td" valign="top"><p>Parameter-prefix + archive-directory + "\\" + archive-name</p></td></tr></table>

<p>You can put more than one parameter in Parameter-prefix but they must be followed by the archive full path.</p>
<p></p>
<p>restorePbCmd restores inflate and remove associative tables from pbCmd.xml. To restore inflate or remove, it invokes the restoreHash method.</p>

<p>The archives associative table contains Archive objects.</p>
<p>The Archive class maintains the download location, the owner, size, upload time, documentation URL and state of the archive. Archive has a constructor to create a new Archive object, a constructor to restore an Archive object from PbArchives.xml (with a XmlReader parameter) and a method WriteXml to serialize onto  PbArchives.xml.</p>

<p>ThreadRun waits 30 minutes or for a pulse. Then it checks a toStop Boolean. It toStop is true, it terminates. OnStop just sets toStop and issues the pulse to gracefully terminate the worker thread.</p><a name="toc27"><h3><font class="Heading-3">CleanupThread.cs</font></h3></a><p>CleanupThread implements</p>
<ul><li><p>A constructor that restores the configuration from cleanup.xml</p></li>
<li><p>Two logging methods, error and log</p></li>
<li><p>ThreadRun</p></li>
</ul>
<p></p>
<p>Here is an example of cleanup.xml:</p>
<p></p>
<table class="cuckoo-table"><tr name="tr0"><td class="cuckoo-td" valign="top"><p><cleanup></p><p><repository></p><p><url>http://localhost/PageBox/Repository/WebServices/Retry.asmx</url></p><p><user>admin</user></p><p><password>admin</password></p><p></repository></p><p><repository></p><p><url>http://localhost/PageBox/Repository2/WebServices/Retry.asmx</url></p><p><user>admin</user></p><p><password>admin</password></p><p></repository></p><p></cleanup></p></td></tr></table>
<p></p>
<p>For each Repository, cleanup.xml contains</p>
<ol><li><p class="FormGet">The URL of its Retry Web Service</p></li>
<li><p class="FormGet">A user name and password of a valid administrator account on that Repository</p></li>
</ol>
<p></p>
<p>The CleanupThread restores cleanup.xml on an ArrayList of RepositoryEntry.</p>
<p>At each loop, ThreadRun enumerates the ArrayList and calls for each Repository the Cleanup method of the Retry proxy.</p>
<p></p>
<p>error writes an error entry on the Application Event log with a RepoCleanup source.</p>
<p>log writes an information entry on the Application Event log with a RepoCleanup source if the logging mode, toLog is true.</p><a name="toc28"><h3><font class="Heading-3">Retry.cs</font></h3></a><p>Retry.cs is a SOAP proxy. It has been generated from the Retry Web service of the Repository using wsdl.exe. The constructor has been modified to set the Web service URL, which has to be the Repository URL.</p><a name="toc29"><h3><font class="Heading-3">ProjectInstaller.cs</font></h3></a><p>ProjectInstaller.cs is a generated class responsible for the installation and de-installation of the Windows service.</p>
<p></p>
<p>In .NET beta 2, we must set the service user and password. Even in Release version, because RepoCleanup can invoke Retry on other machines, we should use a network-enabled account with write access to the registry.</p>
<p></p>
<p>To avoid hard coding the user and password, during installation and de-installation, ProjectInstaller prompts for the user name and password.</p><a name="toc30"><h2><font class="Heading-2">TestRepoCleanup</font></h2></a><p>TestRepoCleanup was designed to test RepoCleanup functions.</p>
<p>Therefore it includes the same classes as RepoCleanup:</p>
<ul><li><p>CleanupThread.cs</p></li>
<li><p>Retry.cs</p></li>
</ul>
<p></p>
<p>You can use it to test your modifications.</p>
<p>It is also user-friendlier than regedit and the Windows service startup parameters to set the registry entries.</p>
<p></p>
<p>TestRepoCleanup uses a Windows form, TestCleanup.</p><a name="toc31"><h3><font class="Heading-3">TestCleanup.cs</font></h3></a><p>The TestCleanup form contains two buttons, Start and Stop.</p>
<p>The TestCleanup class contains three methods:</p>
<ul><li><p>The constructor that retrieves the cleanup.xml path and the logging mode from the registry. It also sets a text box and a check box accordingly</p></li>
<li><p>OnStart called when you click on the Start button. It retrieves the content of the text box and the check box, updates the registry and creates a CleanupThread and a worker thread where the ThreadRun method of CleanupThread will run</p></li>
<li><p>OnStop called when you click on the Stop button. It sets toStop and issues a pulse to gracefully terminate the worker thread</p></li>
</ul>
