builds failing in Eclipse 3.6
All: I could use some tips about how to troubleshoot ant build problems. I'm sure this has to do with the fact that I've updated to Eclipse 3.6. I'm running the cocoa 64-bit version. I haven't been able to build any apps this evening. I'm using the conventional method: right-click on build.xml Run As Ant Build I've never run into build problems failures like this so I've never had to look into something like this.

Re: builds failing in Eclipse 3.6
Hi Tim, I don't see this behavior with 3.6. When I do the same on a project I've never built this way before (I use Hudson - it's just too awesome) it does fail, but with error messages in the console saying it can't find ERExtensions because I don't have the compiled Wonder frameworks anywhere (see: I use Hudson). 1) Is the build.xml file a stock one or do you have modifications? 2) Can you paste the contents of your build.properties file here? 3) What are the contents of the Eclipse Menu - Preferences - WOLips - Build - WOLips Properties File setting? 4) If #3 isn't blank, what are the contents of that file?

Re: Stuck on long response page... IE
While I use autolocking ECs in R-R logic, I never use autolocking ECs in any of my background tasks, just manual-locking ECs and plain old ec.lock/try/finally/ec.unlock - so always on my own there ;-) I only pass EOGlobalIDs to background tasks - so I don't have locking issues. I create all tasks as simple Callables (if I want to return a result) or Runnables (no result) and I use the java.util.concurrent Executor stuff for thread execution.

Re: ?? about opportunistic locking...
Hi! I see the point of your solution (doing whatever has to be done as soon as possible), but like Mike, I believe it has many problems: 1) Your delegate works for situations where different attributes of the same object are modified by different threads. You merge the changes made by the first thread into the second thread EC, and when you finally save, you have the object with all the changes applied. But what about the situation where both threads changed the same attribute? On the example I sent you some days ago, the attribute is a sort-of counter, so the final value depends on the initial one. If you ignore the changes made by other threads, you will be corrupting your logic. You need to be notified in the most catastrophic way possible that you WILL corrupt data if you save. Of course, you could write a specific delegate for that, but... 2) ... as said, your delegate can not throw an exception in the correct thread, which would be the best way to tell you to stop whatever you are doing and start all over again. So I add my voice to Mike's and I ask again, how can you make the second thread be notified of the problem? :) 3) You *still* have to deal with inter-instances OL exceptions, and write code for that. Why write two pieces of code in different places to do the same thing? :) 4) All this depends a lot on what you are trying to do. In Survs, for instance, there are some situations where we read a lot of objects, process them, and save them. This has to be done with all the possible guarantees that no other thread or instance is modifying the same values. The logic is so complex that I simply don't care about dealing gracefully with this. If it fails, I throw it all away and try to do everything again. So, I still would need that exception, or any other mechanism that prevented me from saving (and, by consequence, corrupting) my data. 5) Even if the delegate has some way of throwing the exception in the correct thread, you would have to be ready to catch that exception during the whole EC's existence and not only during the saving. That would lead to more complex code and error handling. And, BTW, another detail for the most curious readers... Application.Application: C1 1274149686265 Application.Application: C2 1274149686265 If this attribute was an integer or long (with the timestamp, for instance) and not a string, in this specific situation, the second commit would not produce any SQL statement. Why? :) Yours Miguel Arroz On 2010/05/18, at 03:33, Mark Ritchie wrote: Hey Mike! On 17/May/2010, at 4:24 PM, Mike Schrag wrote: so here's your challenge ... make this fail with an optimistic lock exception when EC2 saves (which is what would happen if EC1 was in another instance): But that's the point... When an EO in your application changes, you are notified via the delegate! You don't have to wait until you try to saveChanges and get the exception. I agree with what others have posted recently on this topic, getting notified of a collision at the earliest point is much preferred!

Re: ?? about opportunistic locking...
Sent from my iPhone As far as I can tell, this API seems to be one that must have come from the desktop version of EOF where you're always in-process to your changes. Those API's are all dead to me. Yes, of course this design is from 'real' EOF! ObjC EOF and AppKit on NeXTSTEP/OPENSTEP! ;-) Dead or not, it's the history which forms what we have today. No no I mean api's that presume that you're living in a single instance are dead to me. Clearly i'm a fan of the apis of our ancenstors :) This is what I've used in the past (since ObjC days) and I don't know of a case where it fails. This depends on your definition of fail. I agree that for the way you're using it it works. For the ACTUAL complaint I have, it seems insufficient. I'm also not sure you even run in the right thread to throw that exception. This responds to ObjectsChangedInStore, which probably means it runs in EC1's thread? Or does it queue up and run in EC2's thread when in performRecentChanges or something? Regardless, I suspect to make inter-instance and intra-instance behavior match, you're going to have to do a lot more work ... hence my gripe. Those two cases need to be different! If anything, the inter-instance case is broken in that it doesn't properly notify EC's in other running instances that objects they are interested in have become invalid! However, until we have EC's properly hooked into the psychic-friends network, I don't see how that's going to happen. This is my point though. That problem is close to unsolvable, which means the correct approach from a consistency standpoint would be for same-instance to work like multi-instance. If you can get an optimistic lock on ec2.saveChanges out of this technique, I'll be a fan of it (because then we can just wire this into Wonder on all EC's and have this problem fixed or at least an opt-in feature), but I'm still not convinced yet. But that's just it, I don't want to have ec2.saveChanges() fail. By the time that ec2 is back to running, it's EO's have been updated and it's good to save! No they're merged via some magical merge policy that doesn't involve the user which hid the fact that a locked attribute is being overwritten, negating the entire point of an optimistic locking system as a means of data protection. The delegate gives the application developer the control to handle this case in way specific to their application implementation. Something that I could not divine a general solution too! I see this exactly backwards from you. Optimistic lock failure is this to me. You can catch it and do everything you're describing here (see tolerant ec in wonder) but you can't implement a proper optimistic locking system with the delegate (ok ... It's probably possible ... But clearly non-obvious). Why even have lock attributes if you let a different ec stomp on them. And I still come back to the issue of presenting this conflict to the user, which is most likely what actually has to happen to make this work properly. To do that with the delegate you'd have to do a bunch of tedious work for what should be a relatively rate situation. And you still have to write all your optimistic locking code because it can still happen. So still you're left with two implementations if what is, for all intents and purposes, the exact same problem manifesting in two different api's. And yes, by the by, I'm pretty sure that you're correct that when the delegate is called, it's within the thread of the EC which posted the notification and thus throwing any exception would never make it to the handler of another EC. Nor should it! ;-) Bah humbug! Now, having said all that, I would be open to the idea of making this easier to understand for new developers however that must not come at the cost of sacrificing the notification that objects have changed from what you thought they were. M. I have an easy way to make it easier for new developers to understand. Simply make optimistic locking the single way to handle merge conflicts, and add support for core data's merge policy API to provide a default merge policy in the event that you don't want to deal with it per-ec. I'm not in favor of removing that API btw ... I just don't think it adequately addresses the issues I have. I have also decided, after much thought, that even though you are wrong, we can still remain friends. Even with your wrongness. It's a burden I shall have to carry with me ;) What in the world possessed me to take this thread on with the iPhone keyboard?

-Xmx launch parameter
Hi, I'm trying to increase the memory allocation for my application but my app won't start beyond -Xmx 2048 (8 gigs on 10.5 OS X server, WO 5.4.3). I've tried adding launch parameters in Eclipse and JavaMonitor. I can't find a reference to this value in the .woa, what else do I need to modify? Any ideas?

Re: JProfiler / WOLips integration
Hi, I have played around and tried to use JProfile 6 with WOLips for a few hours, but now it looks like it Works. I am using : OSX 10.6.3 Maclipse 3.5.1 WOLips 6049 JProfiler 6.0.3 At first after trying JProfiler 6.0.3, I got also the Error Message and nothing won't work. An internal error occurred during: Launching MyApp. com.jprofiler.integrations.eclipse.internal.ProfilingSession.createProfilingSession(Lorg/eclipse/debug/core/model/ILaunchConfigurationDelegate;Lorg/eclipse/debug/core/ILaunchConfiguration;)Lcom/jprofiler/integrations/eclipse/internal/ProfilingSession; Going back to JProfile 5 and everything was OK. Now the working solution looks like to install from JProfile 5 the Eclipse IDE to dropIns Folder (com.jprofiler.integrations.eclipse) but set in Eclipse the JProfiler executable to JProfiler 6. Now JProfiler 6 boots up and works. I have only played 40 minutes yet, but it looks fine for now. Ken Ishimoto On 2009/12/16, at 18:19, Giles Palmer wrote: Hi Trying to set up JProfiler with WOLips.

Uploading files larger than 2.1 GB fails
Hi All, We have been working on cracking the 2.1GB limit for file uploads using WebObjects, and no matter what approach we use, we are hitting an exception like this: DiskTool DEBUG NSLog (46 appendln) - com.webobjects.appserver._private.WOHttpIO Unable to parse content-length header: '2182961242'. DiskTool WARN NSLog (43 appendln) - WOWorkerThread id=7 socket=Socket[addr=/0:0:0:0:0:0:0:1%0,port=49397,localport=55566] Exception while creating request: java.lang.IllegalArgumentException: er.extensions.appserver.ERXRequest: Can not initialize a WORequest with a null method.; dropping connection [2010-5-18 12:55:50 EDT] WorkerThread7 java.lang.IllegalArgumentException: er.extensions.appserver.ERXRequest: Can not initialize a WORequest with a null method. at com.webobjects.appserver.WORequest.init(WORequest.java:242) at er.extensions.appserver.ERXRequest.init(ERXRequest.java:61) at er.extensions.appserver.ERXApplication._createRequest(ERXApplication.java:1298) at com.zenn.id.IDApplication._createRequest(IDApplication.java:50001) at com.steeplechase.disktool.Application._createRequest(Application.java:50001) at er.extensions.appserver.ERXApplication.createRequest(ERXApplication.java:1268) at com.zenn.id.IDApplication.createRequest(IDApplication.java:50001) at com.steeplechase.disktool.Application.createRequest(Application.java:50001) at com.webobjects.appserver._private.WOHttpIO.readRequestFromSocket(WOHttpIO.java:380) at com.webobjects.appserver._private.WOWorkerThread.runOnce(WOWorkerThread.java:88) at com.webobjects.appserver._private.WOWorkerThread.run(WOWorkerThread.java:226) at java.lang.Thread.run(Thread.java:637) After decompiling WOHttpIO it appears that the contentLength is still an integer in the WO 5.4.3 version of WOHttpIO. These exceptions appear to happen on the second call to WOHttpIO.readRequestFromSocket where a WORequest is initialized. With files smaller than 2.1 GB everything works fine, anything larger, and we get an immediate exception message. readRequestFromSocket is generally called a second time after the file upload finishes. We have experienced this behavior when using both WOFileUpload and AjaxFlexibleFileUpload, using the following bindings: bufferSize = $bufferSize streamToFilePath = $streamToFilePath mimeType = $mimeType filePath = $filePath finalFilePath = $finalFilePath We have experienced the same problem when using the StreamActionRequestHandler ( wis ) and getting to the contentStream directly. This is ideally how we would like to handle large files in order to keep the memory requirements as low as possible. Every one of our approaches works beautifully, unless we try to upload gigantic files. Is anyone else uploading anything larger than 2.1 GB using a WebObjects application? Thanks a lot in advance for any pointers or advice! Uli PS: we've tested with an April build of Project Wonder and the latest available Hudson build 85 and experienced the same issue with WO 5.3.3. ___ Do not post admin requests to the list.

Invalidating Objects
Hello; As part of a built-in change notification facility, I am using EOObjectStoreCoordinator.invalidateObjectsWithGlobalIDs(..) with the relevant OSC locked. All use of other editing contexts are locked and unlocked correctly. Occasionally I seem to end up with disappearing snapshots where all the values of the snapshot go to NULL -- I can only imagine this would be linked to my use of 'invalidate..'. Other new editing contexts then see the NULLed-out EO and the EO does not seem to re-fault in that instance. When that corrupted EO is used in some sort of qualifier, EOF will treat the primary-key qualifier as looking for NULL. Any ideas where to look or has anybody else had this problem and has any pointers? cheers. ___ Andrew Lindesay www.silvereye.co.nz ___ Do not post admin requests to the list. They will be ignored.
