• RuntimeException from xmlbeans - can't find compiled schema

  - by findango

  I'm getting a RuntimeException while executing some code that depends on generated xmlbeans classes. I can't figure out if this is: me missing something during code-generation or packaging a runtime dependency missing a misleading error message, and I should be looking elsewhere. The xbean.jar version is the same in the build and execution environment. Anyone seen this before or have any ideas? Thanks. ...snip...

• heroku time zone problem

  - by Ole Morten Amundsen

  Why does Time.now yield the server local time when I have set the another time zone in my environment.rb config.time_zone = 'Copenhagen' I've put this in a view <p> Time.zone <%= Time.zone %> </p> <p> Time.now <%= Time.now %> </p> <p> Time.now.utc <%= Time.now.utc %> </p> <p> Time.zone.now <%= Time.zone.now %> </p> <p> Time.zone.today <%= Time.zone.today %> </p> rendering this result on my app at heroku Time.zone (GMT+01:00) Copenhagen Time.now Mon Apr 26 08:28:21 -0700 2010 Time.now.utc Mon Apr 26 15:28:21 UTC 2010 Time.zone.now 2010-04-26 17:28:21 +0200 Time.zone.today 2010-04-26 Time.zone.now yields the correct result. Do I have to switch from Time.now to Time.zone.now, everywhere? Seems cumbersome. I truly don't care what the local time of the server is, it's giving me loads of trouble due to extensive use of Time.now. Am I misunderstanding anything fundamental here?

• OpenEjb DeploymentLoader.getWebDescriptors NullPointerException

  - by jwmajors81

  I am currently getting the following error when I try to startup an EAR that includes OpenEJB. The error is: java.lang.NullPointerException at org.apache.openejb.config.DeploymentLoader.getWebDescriptors(DeploymentLoader.java:1057) at org.apache.openejb.config.DeploymentLoader.discoverModuleType(DeploymentLoader.java:1162) at org.apache.openejb.config.DeploymentsResolver.processUrls(DeploymentsResolver.java:294) at org.apache.openejb.config.DeploymentsResolver.loadFromClasspath(DeploymentsResolver.java:248) at org.apache.openejb.spring.ClassPathApplication.loadApplications(ClassPathApplication.java:56) at org.apache.openejb.spring.AbstractApplication.deployApplication(AbstractApplication.java:106) at org.apache.openejb.spring.OpenEJB.deployApplication(OpenEJB.java:342) at org.apache.openejb.spring.AbstractApplication.start(AbstractApplication.java:94) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:79) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:618) at org.springframework.beans.factory.annotation.InitDestroyAnnotationBeanPostProcessor$LifecycleElement.invoke(InitDestroyAnnotationBeanPostProcessor.java:340) The environment consists of: - Spring 3.0 - OpenEJB 3.1 - WebSphere 6.1 (Without EJB/Web Service feature packs) - OpenEJB-Spring jar The app-config.xml that configures Spring and OpenEJB looks like: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd" Also please note that I do have a JUnit test that runs against the app-config.xml specified above that can successfully load the application context file.

• Parsing XML with the PHP XMLReader

  - by coffeecoder

  Hi Guys, I am writing program that reads in some XML from the $_POST variable and then parses using the PHP XMLReader and the data extracted input into a database. I am using the XMLReader as the XML supplied will more than likely be too big to place into memory. However I am having some issues, my XML and basic code as are follows: '<?xml version="1.0"?> <data_root> <data> <info>value</info> </data> <action>value</action> </data_root>' $request = $_REQUEST['xml']; $reader = new XMLReader(); $reader->XML($request); while($reader->read()){ //processing code } $reader->close() My problem is that the code will work perfectly if the XML being passed does not have the <?xml version="1.0"?> line, but if i include it, and it will be included when the application goes into a live production environment, the $reader->read() code for the while loop does not work and the XML is not parsed within the while loop. Has anyone seen similar behaviour before or knows why this could be happening? Thanks in advance.

• emacs indentation problem

  - by Gauthier

  I'm really trying to switch to emacs, but learning to setup the environment is a real pain. Everybody says it's worth it, so I just continue. I want my c code to be implemented that way: if(asdf) { asdr = 1; } Depending on the current standard (I know, don't get me started), could be: if(asdf) { asdr = 1; } I can't seem to change the indentation size from 2, it always looks like the GNU standard: if(asdf) { asdr = 1; } , which I dislike. Here is what I have put in my .emacs: ; Warn in C for while();, if(x=0), ... (global-cwarn-mode 1) ; no electric mode in c (c-toggle-electric-state -1) ; indent the current line only if the cursor is at the beginning of the line (setq-default c-tab-always-indent nil) (setq-default c-indent-level 4) (setq-default tab-width 4) (setq-default indent-tabs-mode nil) (setq-default c-basic-offset 4) (setq-default c-basic-indent 4) ; These commands I read about on the web, but they don't work? ;(highlight-tabs) ;(highlight-trailing_whitespace) This did not help, I have still the GNU indent. Anyone?

• How do I escape a LIKE clause using NHibernate Criteria?

  - by Jon Seigel

  The code we're using is straight-forward in this part of the search query: myCriteria.Add( Expression.InsensitiveLike("Code", itemCode, MatchMode.Anywhere)); and this works fine in a production environment. The issue is that one of our clients has item codes that contain % symbols which this query needs to match. The resulting SQL output from this code is similar to: SELECT ... FROM ItemCodes WHERE ... AND Code LIKE '%ItemWith%Symbol%' which clearly explains why they're getting some odd results in item searches. Is there a way to enable escaping using the programmatic Criteria methods? Addendum: We're using a slightly old version of NHibernate, 2.1.0.4000 (current as of writing is 2.1.2.4853), but I checked the release notes, and there was no mention of a fix for this. I didn't find any open issue in their bugtracker either. We're using SQL Server, so I can escape the special characters (%, _, [, and ^) in code really easily, but the point of us using NHibernate was to make our application database-engine-independent as much as possible. Neither Restrictions.InsensitiveLike() nor HqlQueryUtil.GetLikeExpr() escape their inputs, and removing the MatchMode parameter makes no difference as far as escaping goes.

• Axis2 webservice (aar archive) properties file

  - by XpiritO

  Hi there, guys. I'm currently developing a set of SOAP webservices over Axis2, deployed over a clustered WebLogic 10.3.2 environment. My webservices use some user settings that I want to be editable without the need for recompiling and regenerating the AAR archive. With this in mind, I chose to put them into a properties file that is loaded and consumed in runtime. Unfortunately, I'm having some questions about this: As far as I know, to achieve what I want, the only option is to put the properties file into the ../axis2/WEB-INF/classes directory of each one of the deployments (on each WebLogic instance) I currently have on my clustered configuration, and then load the file, as follows (or equivalent, this has not been verified for optimization): InputStreamReader fMainProp = new InputStreamReader(this.getClass().getResourceAsStream("myfile.properties")); Properties mainProp = new Properties(); mainProp.load(fMainProp); This is not as practical as I wanted it to be, because each time I want to alter some setting on the properties file, I have to edit each one of the files (deployed over different WebLogic instances) and there is a high probability of modifying one of these files without modifying the others. What I would like to know is if there is any (better) alternative to accomplish what I want, minimizing the potential conflict of configuration that is created by distributing and replicating the properties file through multiple WebLogic instances.

• Why does the the Java VM not recover after "Too many open files" errors?

  - by Michael

  In certain well-understood circumstances, our application will open too many sockets (database connections) and reach the maximum open files that the OS allows. We understand this; we are fixing the issue and also bumping up the limit. What we can't explain is why parts of our application don't recover even after the number of connections abates and we're well within the limit. In this case, it's an application running under Tomcat. When this happens, we first start seeing "Too many open files" errors: SEVERE: Socket accept failed java.net.SocketException: Too many open files at java.net.PlainSocketImpl.socketAccept(Native Method) at java.net.PlainSocketImpl.accept(PlainSocketImpl.java:390) at java.net.ServerSocket.implAccept(ServerSocket.java:453) at java.net.ServerSocket.accept(ServerSocket.java:421) at org.apache.tomcat.util.net.DefaultServerSocketFactory.acceptSocket(DefaultServerSocketFactory.java:61) at org.apache.tomcat.util.net.JIoEndpoint$Acceptor.run(JIoEndpoint.java:310) at java.lang.Thread.run(Thread.java:619) Eventually, we start seeing NoClassDefFoundErrors inside an application thread that's trying to open HTTP connections: java.lang.NoClassDefFoundError: org/apache/commons/httpclient/protocol/ControllerThreadSocketFactory at org.apache.commons.httpclient.protocol.DefaultProtocolSocketFactory.createSocket(DefaultProtocolSocketFactory.java:128) at org.apache.commons.httpclient.HttpConnection.open(HttpConnection.java:707) at org.apache.commons.httpclient.MultiThreadedHttpConnectionManager$HttpConnectionAdapter.open(MultiThreadedHttpConnectionManager.java:1349) [...] Caused by: java.lang.ClassNotFoundException: org.apache.commons.httpclient.protocol.ControllerThreadSocketFactory at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1387) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1233) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) ... 8 more When the errant connections go away, the server starts accepting connections again, and everything seems ok, but we're left with the latter error constantly being spewed to stderr. Although the application typically logs unloaded classes to stdout, I don't see any such logs just before, during or after the "Too many open files" errors. My initial theory was that the Hotspot JVM would unload seemingly unused classes when it encounters "Too many open files," but if so, it doesn't log the fact. I'd also expect it to recover if that were the case. Platform details: Java(TM) SE Runtime Environment (build 1.6.0_14-b08) Java HotSpot(TM) 64-Bit Server VM (build 14.0-b16, mixed mode) Apache Tomcat Version 6.0.18

• Circular file references not allowed

  - by Program.X

  Hi, I am having a problem in building my solution in VS2008. Normally, it compiles fine in the environment. Sometimes, it fails with: /xxx_WEB/secure/CMSManagedTargetPage.aspx(1): error ASPPARSE: Circular file references are not allowed. I rebuild and it works fine. Now, however, I am in the middle of setting up a CruiseControl.NET system and am testing my checked out code with MSBuild before I integrate the build into CC. Now, everytime I MSBuild, I get: "Q:\cc\xxx\checked out from svn\xxx.sln" (default target) (1) -> (xxx_WEB target) -> /xxx_WEB/secure/CMSManagedTargetPage.aspx(1): error ASPPARSE: Circular file references are not allowed. Problem is, I can't see where this reference is. I have searched for the reference across the entire solution and canf ind no references to the page itself (CMSManagedTargetPage) anywhere other than in the page or its codebehind, or within a string, eg: C:\dev2008\xxx\IWW.xxx.ASPNET\AspxHttpHandler.cs(82): inputFile = context.Server.MapPath("~/secure/CMSManagedTargetPage.aspx"); C:\dev2008\xxx\IWW.xxx.ASPNET\AspxHttpHandler.cs(83): virtualPath = "~/secure/CMSManagedTargetPage.aspx"; My assembly references are also fine (as far as I know). My Web Application is at the "top" of the dependencies, and nothing references it and therefore the faulting page so cannot cause a circular reference. Of course, the page itself may reference something such as a UserControl within the same assembly/web site, but as mentioned earlier, a search on CMSManagedTargetPage yielded no results so this is not happening. Changing the batch attribute in web.config had no effect on MSBuild. I find it very odd that it "sometimes" fails in VS and always fails in MSBuild. Am I missing some subtlety?

• Remove ActiveRecord in Rails 3 (beta)

  - by Splash

  Now that Rails 3 beta is out, I thought I'd have a look at rewriting an app I have just started work on in Rails 3 beta, both to get a feel for it and get a bit of a head-start. The app uses MongoDB and MongoMapper for all of its models nad therefore has no need for ActiveRecord. In the previous version, I am unloading activerecord in the following way: config.frameworks -= [ :active_record ] # inside environment.rb In the latest version this does not work - it just throws an error: /Library/Ruby/Gems/1.8/gems/railties-3.0.0.beta/lib/rails/configuration.rb:126:in `frameworks': config.frameworks in no longer supported. See the generated config/boot.rb for steps on how to limit the frameworks that will be loaded (RuntimeError) from *snip* Of course, I have looked at the boot.rb as it suggested, but as far as I can see, there is no clue here as to how I might go about unloading AR. The reason I need to do this is because not only is it silly to be loading something I don't want, but it is complaining about its inability to make a DB connection even when I try to run a generator for a controller. This is because I've wiped database.yml and replaced it with connection details for MongoDB in order to use this gist for using database.yml for MongoDB connection details. Not sure why it needs to be able to initiate a DB connection at all just to generate a controller anyway.... Is anyone aware of the correct Rails 3 way of doing this?

• Setting WPF RichTextBox width and height according to the size of a monospace font

  - by oxeb

  I am trying to fit a WPF RichTextBox to exactly accommodate a grid of characters in a particular monospace font. I am currently using FormattedText to determine the width and height of my RichTextBox, but the measurements it is providing me with are too small--specifically two characters in width too small. Is there a better way to perform this task? This does not seem to be an appropriate way to determine the size of my control. RichTextBox rtb; rtb = new RichTextBox(); FontFamily fontFamily = new FontFamily("Consolas"); double fontSize = 16; char standardizationCharacter = 'X'; String standardizationLine = ""; for(long loop = 0; loop < columns; loop ++) { standardizationLine += standardizationCharacter; } standardizationLine += Environment.NewLine; String standardizationString = ""; for(long loop = 0; loop < rows; loop ++) { standardizationString += standardizationLine; } Typeface typeface = new Typeface(fontFamily, FontStyles.Normal, FontWeights.Normal, FontStretches.Normal); FormattedText formattedText = new FormattedText(standardizationString, CultureInfo.CurrentCulture, FlowDirection.LeftToRight, typeface, fontSize, Brushes.Black); rtb.Width = formattedText.Width; rtb.Height = formattedText.Height;

• SerializationException Occurring Only in Release Mode

  - by Calvin Nguyen

  Hi, I am working on an ASP.NET web app using Visual Studio 2008 and a third-party library. Things are fine in my development environment. Things are also good if the web app is deployed in Debug configuration. However, when it is deployed in Release mode, SerializationExceptions appear intermittently, breaking other functionality. In the Windows event log, the following error can be seen: "An unhandled exception occurred and the process was terminated. Application ID: DefaultDomain Process ID: 3972 Exception: System.Runtime.Serialization.SerializationException Message: Unable to find assembly 'MyThirdPartyLibrary, Version=1.234.5.67, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89'.

Using FUSLOGVW.exe (i.e., Assembly Binding Log Viewer), I can see the problem is that IIS attempts to find MyThirdPartyLibrary in directory C:\windows\system32\inetsrv. It refuses to look in the bin folder of the web app, where the DLL is actually located. Does anyone know what the problem is? Thanks, Calvin

• Linux Kernel programming: trying to get vm_area_struct->vm_start crashes kernel

  - by confusedKid

  Hi, this is for an assignment at school, where I need to determine the size of the processes on the system using a system call. My code is as follows: ... struct task_struct *p; struct vm_area_struct *v; struct mm_struct *m; read_lock(&tasklist_lock); for_each_process(p) { printk("%ld\n", p->pid); m = p->mm; v = m->mmap; long start = v->vm_start; printk("vm_start is %ld\n", start); } read_unlock(&tasklist_lock); ... When I run a user level program that calls this system call, the output that I get is: 1 vm_start is 134512640 2 EIP: 0073:[<0806e352] CPU: 0 Not tainted ESP: 007b:0f7ecf04 EFLAGS: 00010246 Not tainted EAX: 00000000 EBX: 0fc587c0 ECX: 081fbb58 EDX: 00000000 ESI: bf88efe0 EDI: 0f482284 EBP: 0f7ecf10 DS: 007b ES: 007b 081f9bc0: [<08069ae8] show_regs+0xb4/0xb9 081f9bec: [<080587ac] segv+0x225/0x23d 081f9c8c: [<08058582] segv_handler+0x4f/0x54 081f9cac: [<08067453] sig_handler_common_skas+0xb7/0xd4 081f9cd4: [<08064748] sig_handler+0x34/0x44 081f9cec: [<080648b5] handle_signal+0x4c/0x7a 081f9d0c: [<08066227] hard_handler+0xf/0x14 081f9d1c: [<00776420] 0x776420 Kernel panic - not syncing: Kernel mode fault at addr 0x0, ip 0x806e352 EIP: 0073:[<400ea0f2] CPU: 0 Not tainted ESP: 007b:bf88ef9c EFLAGS: 00000246 Not tainted EAX: ffffffda EBX: 00000000 ECX: bf88efc8 EDX: 080483c8 ESI: 00000000 EDI: bf88efe0 EBP: bf88f038 DS: 007b ES: 007b 081f9b28: [<08069ae8] show_regs+0xb4/0xb9 081f9b54: [<08058a1a] panic_exit+0x25/0x3f 081f9b68: [<08084f54] notifier_call_chain+0x21/0x46 081f9b88: [<08084fef] __atomic_notifier_call_chain+0x17/0x19 081f9ba4: [<08085006] atomic_notifier_call_chain+0x15/0x17 081f9bc0: [<0807039a] panic+0x52/0xd8 081f9be0: [<080587ba] segv+0x233/0x23d 081f9c8c: [<08058582] segv_handler+0x4f/0x54 081f9cac: [<08067453] sig_handler_common_skas+0xb7/0xd4 081f9cd4: [<08064748] sig_handler+0x34/0x44 081f9cec: [<080648b5] handle_signal+0x4c/0x7a 081f9d0c: [<08066227] hard_handler+0xf/0x14 081f9d1c: [<00776420] 0x776420 The first process (pid = 1) gave me the vm_start without any problems, but when I try to access the second process, the kernel crashes.

• SSIS Intermittent variable error: The system cannot find the file specified

  - by Ben

  Our SSIS pacakges a structured as one Control package and many child packages (about 30) that are invoked from the control package. The child packages are invoked with Execute Package Task. There is one Execute Package Task per child package. Each Execute Package Task uses File Connection Manager to specify path to the child package dtsx file. There is one File Connection Manager per child package. Each File Connection Manager has an expression defined for ConnectionString property. This expression looks like this: @[Template::FolderPackages]+"MyPackage.dtsx", the file name is different for each package. The variable (FolderPackages) is specified in the SSIS package configuration file. The error that is generated during run time is "Error 0x80070002 while loading package file "MyPackage.dtsx". The system cannot find the file specified." The package that fails is different from run to run and sometimes no packages fail at all. This is when run on exactly the same environment/data etc. I ran FileMon during this error and found out that when the error happens SSIS tries to read the dtsx file from a wrong place, namely from system32. I checked that this is identical to what would happen if @[Template::FolderPackages] variable were empty, but because the very same variable is used for every child package and works for some but doesn't work sometimes for others, I have no expalnation to this fact. Anything obvious, or time to raise a support call with Microsoft?

• How to produce an HTTP 403-equivalent WCF Message from an IErrorHandler?

  - by Andras Zoltan

  I want to write an IErrorHandler implementation that will handle AuthenticationException instances (a proprietary type), and then in the implementation of ProvideFault provide a traditional Http Response with a status code of 403 as the fault message. So far I have my first best guess wired into a service, but WCF appears to be ignoring the output message completely, even though the error handler is being called. At the moment, the code looks like this: public class AuthWeb403ErrorHandler : IErrorHandler { #region IErrorHandler Members public bool HandleError(Exception error) { return error is AuthenticationException; } public void ProvideFault(Exception error, MessageVersion version, ref Message fault) { //first attempt - just a stab in the dark, really HttpResponseMessageProperty property = new HttpResponseMessageProperty(); property.SuppressEntityBody = true; property.StatusCode = System.Net.HttpStatusCode.Forbidden; property.StatusDescription = "Forbidden"; var m = Message.CreateMessage(version, null); m.Properties[HttpResponseMessageProperty.Name] = property; fault = m; } #endregion } With this in place, I just get the standard WCF html 'The server encountered an error processing the request. See server logs for more details.' - which is what would happen if there was no IErrorHandler. Is this a feature of the behaviours added by WebServiceHost? Or is it because the message I'm building is simply wrong!? I can verify that the event log is indeed not receiving anything. My current test environment is a WebGet method (both XML and Json) hosted in a service that is created with the WebServiceHostFactory, and Asp.Net compatibility switched off. The service method simply throws the exception in question.

• Need help troubleshooting why Solr wont start (or why solr admin page wont show)

  - by Camran

  I can't get Solr working. I have Jetty, and my server OS is Ubuntu 9.10. It is a VPS server. So, when I execute the java -jar start.jar everything seems fine. I even do a netstat to check if there are any listeners on the port before the start and after the start, and it seems solr is starting. However, I cant access the admin page. I have even turned off the firewall. Here is some info about my server: I have changed DocumentRoot to var/www/SV/ I have Apache2, PHP5, MySql installed I have "disabled" iptables firewall I have removed the htaccess files (I used them to passw protect my site under develop) I have installed JRE (NOT JDK) on my server. I use the "example" which comes with Solr, so I use Jetty as container on my Server. My Server has 768MB RAM Doing a java -version command shows this: java version "1.6.0_15" Java(TM) SE Runtime Environment (build 1.6.0_15-b03) Java HotSpot(TM) Client VM (build 14.1-b02, mixed mode) And in the terminal the last lines when executing start.jar is: May 29, 2010 1:30:03 PM org.apache.solr.core.SolrCore registerSearcher INFO: [] Registered new searcher Searcher@1dc64a5 main NOTE: Also before this last line, there is a line which makes me suspicious: Started SocketConnector @ 0.0.0.0:8983 // Should this be with leading zeros? Is there any ways you know to troubleshoot this? Memory issue maybe? Thanks

• PHP SoapClient() function returning a single XML string

  - by gjb

  I am having difficulty with the PHP SoapClient() function. The SOAP request is successful, but the response is returned as an object containing a single XML string with the key "any". For example: <?php $params = array('strUsername' => 'Test', 'strPassword' => 'Test'); $client=new SoapClient('http://www.example.com/webservice.asmx?wsdl', array('features' => SOAP_SINGLE_ELEMENT_ARRAYS)); $result = $client->strExampleCall($params); print_r($result); ?> This outputs the following: stdClass Object ( [strExampleCallResult] => stdClass Object ( [any] => <Response xmlns="" release="1.0.0" environment="Production" lang="en-GB"><ApplicationArea><Sender><SenderId>0</SenderId><ReferenceId>0</ReferenceId></Sender><Destination><DestinationId>1</DestinationId></Destination></ApplicationArea><DataArea><Result>1</Result></DataArea></Response> ) ) Subsequently, I cannot access properties of the object as I'd expect to: echo $result->strExampleCallResult->Response->DataArea->Result; Why isn't PHP parsing the SOAP response into properties of the returned object? I am using PHP 5.3.0 and believe the SOAP server is running .NET. Any suggestions will be much appreciated.

• How to get stack trace information for logging in production when using the GAC

  - by Jonathan Parker

  I would like to get stack trace (file name and line number) information for logging exceptions etc. in a production environment. The DLLs are installed in the GAC. Is there any way to do this? This article says about putting PDB files in the GAC: You can spot these easily because they will say you need to copy the debug symbols (.pdb file) to the GAC. In and of itself, that will not work. I know this article refers to debugging with VS but I thought it might apply to logging the stacktrace also. I've followed the instructions for the answer to this question except for unchecking Optimize code which they said was optional. I copied the dlls and pdbs into the GAC but I'm still not getting the stack trace information. Here's what I get in the log file for the stack trace: OnAuthenticate at offset 161 in file:line:column <filename unknown>:0:0 ValidateUser at offset 427 in file:line:column <filename unknown>:0:0 LogException at offset 218 in file:line:column <filename unknown>:0:0 I'm using NLog. My NLog layout is: layout="${date:format=s}|${level}|${callsite}|${identity}|${message}|${stacktrace:format=Raw}" ${stacktrace:format=Raw} being the relevant part.

• How to resolve deprecation warnings for OpenSSL::Cipher::Cipher#encrypt

  - by Olly

  I've just upgraded my Mac to Snow Leopard and got my Rails environment up and running. The only difference -- OSX aside -- with my previous install is that I'm now running ruby 1.8.7 (2008-08-11 patchlevel 72) [universal-darwin10.0] (Snow Leopard default) rather than 1.8.6. I'm now seeing deprecation warnings relating to OpenSSL when I run my code: warning: argumtents for OpenSSL::Cipher::Cipher#encrypt and OpenSSL::Cipher::Cipher#decrypt were deprecated; use OpenSSL::Cipher::Cipher#pkcs5_keyivgen to derive key and IV Example of my code which is causing these warnings (it decodes an encrypted string) on line 4: 1. def decrypt(data) 2. encryptor = OpenSSL::Cipher::Cipher.new('DES-EDE3-CBC') 3. key = "my key" 4. encryptor.decrypt(key) 5. text = encryptor.update(data) 6. text << encryptor.final 7. end I'm struggling to understand how I can resolve this, and Google isn't really helping. Should I try and downgrade to Ruby 1.8.6 (and if so, what's the best way of doing this?), should I try and just hide the warnings (bury my head in the sand?!) or is there an easy fix I can apply in the code?
