network volume names changing etc.
I've noticed that Mac OS sometimes silently changes the UNIX mount name of network volumes. For example, if I mount a network volume of Media, it would normally be /Volumes/Media, but sometimes it isn't. For example, if another user on the same machine mounts Media first, then you might end up having it mounted as /Volumes/Media-1 or some such. Is there any document that discusses it? And what is the recommended way to store paths in this case? I don't know if its right, but I'm in the habit of storing UNIX paths, but this doesn't work very well for network shares because the UNIX path keeps changing because of the above. How can I store a path and get it back in a way that takes into account the above? Also as an aside, is there a way to have network volumes mounted for all users at once instead of just one user at a time? ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Bindings don't work with cut and paste
I have a NSTextView's value bound to an object. I do not have Continuous update turned on. The binding works when I type into the field and exit the field. However if I *paste* text into the field, then exit the field, the binding set: method is never called.

encoding of file names
If I take a string from an NSTextField with an accented character: café and I make this into a file name and write a file, then I read that file name back in (using NSFileManager contentsOfDirectoryAtPath), then the string read back in, still looks the same: an accented café, but the strings don't compare anymore. The one in the text field was unichars: 99,97,102,233 and the one in the file name is now99,97,102,101,769.

Joining App Developer Program
Sorry if this is a little off topic, but I don't know who to ask and I can't get any sense out of Apple. I attempted to join the Mac dev program the day Steve Jobs announced it. A couple of days later I was asked to submit some company documents, which I did, and which was acknowledged. Now I've been waiting a week with no word, and I'm eager to start making any necessary changes to my app to support the app store. When I go to the site it says we are trying to contact the legal representative of your company, which kind of contradicts a separate email which says they are processing my documentation. How long should this process take? When should I get worried? Is there any way to get access to technical documentation without waiting?

Multiple instances of [NSUserDefaults standardUserDefaults]

Re: Multiple instances of [NSUserDefaults standardUserDefaults]
Some stuff on the net seems to indicate that NSUserDefaults does support KVO. If it doesn't, how would NSUserDefaultsController accurately notify of all changes to NSUserDefaults?

Are you observing an instance of NSUserDefaults or NSUserDefaultsController? NSUD doesn't support KVO – perhaps that's the problem? Also, for testing at least, you might as well allocate your own NSUserDefaultsController instance and stick it in an ivar.

core data could not merge changes
I've done a lot of core data development, but all using the XML file format. Now I'm trying to work with sqlite. I've got an app that was working, but when I change to sqllite I get errors. I've got a really basic application, nothing particularly special about it as far as I see, and when I change something and hit save, I get the sheet The document blah etc could not be saved.

Re: Stealing settings from Mail.app
Hi,
I personally use smtp.me.com as my server, so I think you need to add that.
As far as I see, [@macdonald.org rangeOfString:@mac].location would be a
wrong match. I think you need to look for
[hostName hasSuffix:@.me.com] || [hostName hasSuffix:@.mac.com]
Right now I'm using http://github.com/tcurdt/edmessage to send mails.

There's no bug in the code, so far as I know (I can be wrong), the smtp server
for a MobileMe account remains smtp.mac.com. The userName must be the user name

Reordered columns and [tableView editColumn:0 row:ind withEvent:nil select:YES];
I've got some code that uses editColumn:0 to force the user into edit mode on the first column. But I've noticed that if user column reordering is allowed, this no longer edits the correct column. This seems odd to me because I thought Cocoa pretty much shielded the programmer from all the user reordering stuff. Even more oddly, if the user puts a checkbox as the first column, the checkbox seems to start behaving like a text box, albeit with invisible characters. Could I be doing something wrong, or is this some kind of bug? And do I have to somehow translate column 0 to find out the real column? I know Java tables have methods to translate between model and view column numbers because of user reordering, but I haven't noticed such a thing in Cocoa. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Tricky binding and continuous update problem
I've got a problem that I had working, but my app suddenly seems broken, and I'm not sure if I did something or what. All I know is old versions of my app work, but now my code base doesn't. I've got a UI with a NSTableView at the top, and some individual fields at the bottom. Typical UI where you click on a table row and it shows you the values in the fields. Now one of the fields shown in the table is a derived value from the base fields. I have continuous update values set in the NSTextField at the bottom. So what I expect as you type in the field, the value in the table gets continuously updated also. (I'm using keyPathsForValuesAffecting etc for the derived field). But what's happening is if I type in the lower field, the value gets sent to the derived field in the table, but then Text field gets immediately set back to the original value. So the effect is you type one character and it is lost as far as the lower field is concerned, but the derived value in the table is updated. You can only ever change one character. And also the lower text field loses focus. I've put break points in all the setters and getters, and there seems like no reason for this odd behavior. I can't see how the field would get set back to the old value. If I turn off Continuously Update Value, it works sensibly, albeit not as nice since you've got to exit the field to have everything in synch.

Look at any of Apple's Sample Code.

That's the way most apps work. You did not mention using an array controller. To insure data integrity in case user tabs out, abruptly closes the window, etc., do not bind directly to the model. Instead, bind your text fields (detail views) to an NSArrayController to which the table columns are also bound. As a matter of fact, if you didn't use an array controller, you'd better look at Apple's DepartmentAndEmployees sample code and be prepared for a little re-work. There may be a way to make your design paradigm work, but why bother? The way I understand it, the NSArrayController superclass NSObjectController fulfills the same purpose of data integrity if you can't bind to an array controller, for example if you have an Inspector in another nib. NSObjectController seems like a heavy weight for this purpose, but it works. For an example of this, in DepartmentAndEmployees's MyDocument.nib, look at the NSObjectController named 'Department Controller'. It seems like it's useless but it's not. Probably someone else can give a more in-depth explanation. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Tricky binding and continuous update problem
How does it wreak havoc with undo? Undo seems to work still. In something like TextExpander, you change the textfield where your expansion goes, and the table in the left hand side changes as you type. That's what I was aiming for. But I've found why it suddenly stopped working. I stumbled upon the URL below. Apparently the Automatically rearrange content for the NSArrayController makes this all go awry. It seems like I can choose between auto rearrange content, or continuously update values, but not both. Don't know if this is a bug or if there is some reason for it. http://stackoverflow.com/questions/1028700/core-data-strange-bindings-error-on-re-opening-a-document-help - Original Message From: Kyle Sluder kyle.slu...@gmail.com To: Chris Idou idou...@yahoo.com Cc: Jerry Krinock je...@ieee.org; cocoa-dev@lists.apple.com Sent: Wed, 7 April, 2010 11:21:28 AM Subject: Re: Tricky binding and continuous update problem On Tue, Apr 6, 2010 at 5:28 PM, Chris Idou idou...@yahoo.com wrote: I don't know, it seems to me like having everything always in synch is nicer.

SetFrontProcessWithOptions and NSPanel
I've got a NSPanel HUD that I need to be able to pop up above other applications, but I need to pop only the HUD, and not other windows in my application. So naturally I'm using: SetFrontProcessWithOptions(psn, kSetFrontProcessFrontWindowOnly); However, it still pops up all my windows, and not just the HUD panel. I notice this doesn't happen when it is a regular window. I notice the documentation says that kSetFrontProcessFrontWindowOnly only works for non-floating windows so I've set on the window: [self.windowsetLevel:NSNormalWindowLevel]; and: [(NSPanel *)self.window setFloatingPanel:NO]; But to no avail.

FSEventStreamCreate and File System Events Wierdness
I'm trying to use the file system events api, but what I'm seeing seems wierd. Firstly, the documentation as I read it says you can store the last event id, and pass that to FSEventStreamCreate next time to carry on where you left off. However what I'm seeing if I do that, is it immediately resends me that event. So lets say I process event 877921818. I store that and exit the program. Next time I pass 877921818 to FSEventStreamCreate and I immediately get another callback with event id 877921818, so I end up processing it again. So I'm thinking to myself, maybe what it really wants is the lastevent+1. So I pass 877921819 to FSEventStreamCreate instead. But then what happens is I immediately get a callback with event 877921819. This despite that nothing has changed. (I'm actually monitoring an empty folder, and nothing is changing, not even so much as timestamps or anything). If I pass lastEvent+10 I immediately get a callback with that id, even though nothing has changed. Interestingly, if I monitor multiple folders, it seems to only callback with whichever one is passed in first. It seems like if you pass an explicit event id into FSEventStreamCreate in absolutely insists on giving you an immediate callback that something changed with whichever is the first folder in the list, even though in fact nothing has changed. It seems to be broken in a major way, but its hard to believe something like is is *that* broken. Any comments?

Re: FSEventStreamCreate and File System Events Wierdness
Firstly, I don't think that actually makes sense, given the whole point of the lastEventId. Secondly, it only does it for the first folder you pass in, so it isn't even consistent.

No, I'm not using FSEventStreamCreateRelativeToDevice, I'm using FSEventStreamCreate. What you quote is only relevant to FSEventStreamCreateRelativeToDevice.

Clients can store this value persistently as long as they also store the UUID for the device (obtained via FSEventsCopyUUIDForDevice()). Clients can then later supply this event ID as the sinceWhen parameter to FSEventStreamCreateRelativeToDevice(), as long as its UUID matches what you stored. This works because the FSEvents service stores events in a persistent, per-volume database. In this regard,the stream of event IDs acts like a global, system-wide clock, but bears no relation to any particular timebase. So, are you also storing the UUID and using FSEventStreamCreateRelativeToDevice?

Re: tiffs on pasteboard
Well... now that in 10.6 the pasteboard types are UTI types, I'm not sure that one can say anymore that there is no mapping from files to pasteboard types. And 10.6 Finder puts a public.tiff into the pasteboard in this case, but I would argue it is the wrong tiff.

At least that's what I find documented by Apple. You're correct that promises would overcome some of the inefficiencies (although I can envision other situations where the size would be a problem.) I suspect the real reason is that there isn't a straightforward mapping between file types and pasteboard types. There is not in general any table that says a file with extension .foo contains data that can be stored in a pasteboard using type 'FooPasteboardType'; so the Finder would not be able to decide in all cases what pasteboard type to use for the contents of the dragged/copied file.* You could argue that images are a useful special case; but I suspect that the engineers responsible decided that it was better to remain consistent..

tiffs on pasteboard
I'm trying to read a TIFF off the pasteboard, but it doesn't seem to work for me. What I'm doing is going into Finder, finding a TIFF file and Command-C it. Among other types I then find on the pasteboard are: NeXT TIFF v4.0 pasteboard type and public.tiff If I take either of those from the pasteboard and write the NSData object to a file: [content writeToFile:@/tmp/foo.tiffatomically:YES]; or else if I make an NSImage from the data: [[NSImagealloc] initWithData:content] and display it in an NSImageView then I always see the generic TIFF icon, i.e. the one with a photo of a child scattered on the table, with a loupe on top of it. The same thing happens for JPEGs, GIFS and PNGs, but not for com.apple.icns. If I take the com.apple.icns, it displays correctly.

Re: tiffs on pasteboard
But what are the rules and conventions? Why would Finder put the icon in the pasteboard on the assumption that is what the user wants, but TextEdit would paste in the actual file on the assumption that is what the user wants? It seems schizophrenic. I just want a list of rules of how to use the Pasteboard in a way that conforms to what users expect. If I start ignoring the TIFF part of the pasteboard in favor of the URL on the assumption that is what the user wants, why is the tiff there anyway? And will that get me into trouble in other cases?

The Finder also puts the location of the file on the pasteboard, and I believe TextEdit sees that, recognizes that it's an image file, and reads the file into an image.

Of FontManagers and responder chains
I am trying to implement choosing default fonts, as found in the OS-X 10.6 version of TextEdit's Preferences dialog. i.e., you press a button, and it brings up the Font Chooser, and you select a font and it shows the name of the font in the dialog. Now I thought I had it all working, but the trouble is I have the option in System Preferences, Keyboard prefs called Full Keyboard Access to allow focus in all controls. When I turn that option off, nothing in my dialog has explicit focus, and so it seems, changeFont: is never called, presumably because my delegate object for the window is not in the responder chain. I've tried to explicitly make my window the first responder, and to make the button the first responder, but apparently no dice, they are not allowed to be first responder, or even in the responder chain, because they have no focusable objects. I could change the action for NSFontManager, but this breaks things for other uses of the NSFontManager, and seems like a bad idea. I notice that TextEdit when you press a change font in TextEdit Preferences it explicitly makes the text fields to NOT be first responder, so it seems like it is also using the first responder mechanism to make it work. But I can't seem to. __ Get more done like never before with Yahoo!7 Mail.

Odd window behavior LSUIElement=1
I have an app running without dock icon, and it exhibits odd behavior. Let's say I have existing applications running, A with a window on top of application B. My program pops up a window and forces it to the front. So I have MyApp on top of A on top of B. Now I click on Application A, bringing it to the front. Now I have A on top of MyApp on top of B. Now I quit A. As I quit A, MyApp suddenly pops behind B. The same thing happens whether I programmatically forced MyApp to the front, or whether I bring it to the front by clicking on it. It doesn't happen when I run LSUIElement=0 Can anyone tell me what is going on? __ Get more done like never before with Yahoo!7 Mail.

One change to the NSPointerFunction based collection classes (which support a
number of things that NSArray the like do not) between Leopard and Snow
Leopard was to tighten up the validation of the pointer function validation
such that a handful of non-sensical configurations are detected that weren't
before.
I.e. RKCache is trying to create a set of pointer functions that doesn't make
sense (and for whose behavior is undefined).
As someone else pointed out, RK is most likely RegexKit and, thus, the source
is available and can be fixed. Given the relatively common use of RK*, please
provide a patch to the author so it can be fixed upstream.

It happens twice on startup, and below are the stack traces when it happens:
What does it all mean?

#10x7fff84ac84d1 in +[NSConcretePointerFunctions

#40x10004b633 in +[RKCache load]
One change to the NSPointerFunction based collection classes (which support a
number of things that NSArray the like do not) between Leopard and Snow
Leopard was to tighten up the validation of the pointer function validation
such that a handful of non-sensical configurations are detected that weren't
before.
I.e. RKCache is trying to create a set of pointer functions that doesn't make
sense (and for whose behavior is undefined).
As someone else pointed out, RK is most likely RegexKit and, thus, the source
is available and can be fixed. Given the relatively common use of RK*, please
provide a patch to the author so it can be fixed upstream.

NSDocumentController didCloseAllSelector
The doco for closeAllDocumentsWithDelegate:didCloseAllSelector:contextInfo: says that it should call the didCloseAllSelector. How would one do that?

Re: NSWindowController and GC
The right way is to make sure something in your program retains a pointer to your window controller. Sometimes there will be an obvious place, like a member of the object that created the window controller. That is most typical. Worst case is you retain a pointer in some global variable or similar, but that also has a greater danger that you will forget to zero it out when you are finished with it, and it won't get collected. Some of my temporary dialog box controllers inherit from a class that puts itself in a global dictionary when created, and removes itself when the window closes. From: Bryan Matteson brysco...@gmail.com To: cocoa-dev@lists.apple.com Sent: Thursday, 1 October, 2009 9:20:16 AM Subject: NSWindowController and GC I was just reminded of something. I use GC in my app, and unless I specifically disable collection for a window controller, it's destroyed as soon as it loses key. I solved it by setting the controller as the delegate of the window, disabling collection for the window controller in windowDidLoad, and re-enabling it in windowWillClose:.

Re: NSDocumentController didCloseAllSelector
What I have is a document based app, but it automatically saves everything - I don't want to ask the user. So I'm saving all my documents in closeAllDocumentsWithDelegate. It's working pretty good, the only major hassle is the app doesn't die on machine shutdown, presumably because I wasn't calling didCloseAllSelector. I agree the whole setup is pretty confusing but after ponding it extensively, I think it is more or less sensible, given the need for the RunLoop and so on. (albeit, poorly documented). I'm not sure what you mean you can invoke the method easily enough. Maybe the right way to do it is with NSInvocation. But knowing what I know about objective-c, I can't see how setArgument:atIndex: would be able to know that the second argument is a BOOL which is one byte. Maybe it does know and it all just works.

You don't necessarily have to call anything - looking at the byzantine interactions between all these methods all I can say is, if you can avoid it, do so! What do you want to do? Unless you're overriding - (void)canCloseDocumentWithDelegate:(id)delegate shouldCloseSelector:(SEL)shouldCloseSelector contextInfo:(void *)contextInfo to do something in a non-standard way there's nothing to do. If you are overriding it, you need to handle the whole kit-n-kaboodle, including presenting the alert to the user and saving the document to disk, and finally invoking the mysterious callback selector. I can't actually see an easy way to invoke the callback selector with the signature as given - you need to pass it the document (self), a BOOL and the contextInfo. You can invoke the method directly on the delegate easily enough, but since you're supposed to use the callback supplied, that might not work. The only way I can see to do it is to create an NSInvocation with the selector, set each argument and call invokeWithTarget: passing the delegate.

Snow Leopard, core data, read only and multiple threads
I've got an app that worked on Leopard. I ported it to Snow Leopard SDK 10.6, and now it works on Snow Leopard, but it doesn't work correctly on Leopard anymore. I haven't changed anything that ought to affect this. It's an app with a foreground gui that writes an XML coredata store. A background thread reads the repository and takes action. Both threads have the full core data stack with their own coordinators. As soon as I activate the background thread, the XML store gets set to zero bytes. When I encountered the problem I read the doco and I added the NSReadOnlyPersistentStoreOption when calling addPersistentStoreWithType in the background thread, but that hasn't helped. It wasn't necessary before. Has anyone got any thoughts? And also, how am I going to debug this? Xcode 3.2 doesn't run on 10.5 does it?

Re: building and running on Snow Leopard
Ok, so if I don't desire bug for bug 10.5 compatibility, but I do want it to run on 10.5, then I select 10.6 SDK and 10.5 deployment target, is that right? I'm curious what happens if you use some external frameworks that were built against 10.5 SDK, yet your main app is 10.6 - I assume it will have to go with what your app says, I guess? Also, since I'd like to take advantage of Snow Leopard bug fixes, but I don't want to blow up on Leopard, what is the correct way to test whether you are running on Leopard so that the code at runtime can implement Leopard specific work arounds?

Not quite either. At runtime, your app can only use the frameworks provided on the host system. Just because you linked against the 10.5 SDK doesn't change the fact that Snow Leopard only provides Snow Leopard's frameworks. In general, your app will get the benefit of bug fixes in the Snow Leopard frameworks when running on Snow Leopard. However, there are some bug fixes which Apple has determined would break backward compatibility with apps built and tested on Leopard or earlier. For those fixes, they test which SDK the app was built against. For those built against the pre-Snow Leopard SDK, they continue to provide the old, compatible-bug-buggy behavior. This is documented in the release notes for the affected frameworks. Note that this tests for the SDK that the app was built against. You mentioned deployment target. That's not the same thing. If you build against the 10.6 SDK but with a 10.5 deployment target, it is expected that you will be testing on both 10.6 and 10.5. It is then your code's responsibility to handle both the old framework behavior the new behavior. The Snow Leopard frameworks _do not_ go out of their way to maintain the old behavior in this case.

Re: building and running on Snow Leopard
From: Ken Thomases k...@codeweavers.com Don't test whether you're running on Leopard. Just write your code to cope with either behavior of the framework. Read the release notes for the frameworks on which you rely for more guidance. I think when you see the sorts of bugfixes which are special-cased in this way, it will be obvious how you should code in response. Well I'm thinking of a particular bug on Leopard with MDItemCreate where you have to choose between your program crashing and leaking memory. Apple tells me it is fixed in Snow Leopard.

Re: GC pros and cons
From: James Gregurich bayoubenga...@mac.com I have read up on GC, and I don't like the idea of introducing non-deterministic behavior into my code base. I would question the assertion that GC introduces non-deterministic behavior, unless you consider the time it takes for particular code to execute to be behavior. In which case standard malloc/free is not deterministic either, since algorithms for amalgamating free areas in the heap are not exactly predictable, and the time they take will not be constant across different calls.

I suspect it is for performance reasons. The Objective-C garbage collector is designed to run in a separate thread on the Mac, which means it can run on its own CPU core separate to the main thread. In single-core systems, even on the Mac, performance of Garbage Collected code is very poor because the collector has to share CPU time with the main thread. When Xcode 3 (a GC app) was first released in the Leopard betas there were still quite a few people with single-CPU PowerPC laptops who found that Xcode could barely keep up with their typing. On dual-core machines it was fine. The iPhone has a single-core CPU and a slow one at that, so while I am sure that GC could be turned on, it would probably make developers very unhappy. -- Rob Keniger ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Opinion on managed memory and garbage collection
I've written a reasonably non-trivial app using GC and using a fairly wide range of APIs. I've found several GC bugs in the Apple frameworks, which naturally enough are pretty annoying (as all memory problems are), but I don't think the annoyance is still anywhere near that of having to write memory release code, and then hunt down memory leaks. I haven't noticed GC pauses. It seems to me that the GC collects memory extremely quickly, relative to when it becomes unreachable. Given that it apparently does a lot of work in another thread, I wouldn't expect there to be much pausing in normal applications.

If you were writing a new Cocoa application from scratch, would garbage collection be the preferred method over the reference counting (retain/release) method. Having spent years in Java I would prefer a GC'd approach but I have also seen the great improvement of GC in Java over the years. Therefore, I am also curious on how the new Objective-C design for GC compares. The applications I have in mind are mostly graphic (Quartz 2D) oriented and likely also some OpenGL work. Thanks for your opinions and comments. IMO there are three major reasons to avoid GC at this point: 1) In 10.5 there are still significant bugs in the GC and, more importantly, the GC support in the system frameworks. The GC bugs are generally obscure and hard to hit, the frameworks are much easier to hit and harder to work around. If you search the list archives you'll probably turn up various posts where Apple people tell developers that you can't use this API under GC, or it has some huge speed hit, or the only way to avoid a crash is to deliberately leak an object, etc. Hopefully 10.6 is better, but as always, the people who know can't say and the people who can say don't know. 2) The GC pauses your threads at nondeterministic intervals and for an unknown amount of time in order to scan its stack. If this pause is significant enough, it could cause occasional visible stutter in your graphics output. I have no idea what the chances are of this causing problems for you, but it's something to watch out for. 3) By its very nature of trying to coexist in a C-based language, the GC doesn't cover everything. This is by design. The GC covers ObjC objects (including bridged CoreFoundation objects allocated in the default zone) and raw memory that you explicitly allocate with the collector. Anything that's allocated with raw malloc/free stays outside the garbage collector. This is a big advantage in that any raw C code that you happen to have (or load) will almost certainly Just Work in a garbage collected environment, which I'm sure is a big part of why the Apple GC guys chose to make it work this way. The downside is that your interactions with the collector often become more manual than you might like if you drop out of the Ideal Pure Objective-C World and into the guts of C. The code you write here will offset your savings from not having to write retain/release code, and worse, this code is usually much more complex and error-prone. I have not done a lot of serious work with GC, although I have a half-completed project and some toy projects that use it. My personal impression is that if you're doing a conventional, straightforward OS X program which never colors outside the lines, you're likely to have a good experience with it. If you're after high performance or are doing anything tricky then you're likely to run afoul of it and perhaps wish that you had gone the other way. Retain/release has a long history, is very well understood, and doesn't really require much mental (or typing) overhead once you know it. With GC you're much more like a test pilot at this stage in the game, especially since there are a lot of frameworks deficiencies under GC which are known to Apple but which they haven't actually put into the documentation. (List archives are your friend here.) GC has more risk and potentially more reward. If you can aim for 10.6+, the risk/reward ratio is probably going to be quite a bit lower, although that's just speculation. Obviously the ultimate choice is yours.

Databases on Cocoa (was Re: Invoice program made in Objective c/Cocoa)
The database situation on Cocoa is not great. Apple should spend some of that cash hoard building or buying an object database. If anyone wants an interesting project, the db4o object database which is written in Java and GPLed comes with a program called Sharpen which translates Java into C#. It occurs to me that translating it into C or objective-c would be possible. Nobody would give a rip about core-data if there was a real object database available. On another note, Versant which seems to now run db4o has a very nice object database with c bindings that would probably be really easy to write objective-c bindings for, but its commercial and much too heavy weight for most of our purposes.

Re: Databases on Cocoa (was Re: Invoice program made in Objective c/Cocoa)
Core Data solves that through the use of a SQLite backing store. SQL based data storage is the standard means of achieving incremental retrieval and storage of data in our industry. If Core Data talked to standard databases like Oracle etc, then I can see that as a selling point. But since it doesn't, and since it tries to hide SQLite, it's hard to see how it is much of a selling point. That SQL is pervasive is irrelevant if you're hiding the existence of SQL. If you're going to make it look like an object database, but not talk to widely deployed SQL databases, then you really should make it an object database. I don't know how core-data handles inheritance, but all the ways of doing it with an SQL database make performance suck if you want to do anything serious, and they also make writing SQL queries intractable if one wanted to get some benefits of having an SQL back end. I guess some people don't want to use any inheritance because their problems are simple, and it *can* work for them, but having a proper object database with a query facility or SQL front to it could work for them too. We're in an object world now, and SQL databases can't cut it for many many problems. Accounting style applications, yes they *can* work. But there are vast areas of computing where its just too inefficient. Goto the web site of an object database like Versant and look at the wide variety of customers they have. They don't buy it because they are geeky, but because SQL databases can't do it. At that point, the choices are to fully document the schema and implement a whole bunch more code that tries to detect when someone has done something wrong in the database. Combined with the need to provide some kind of a means of making access to many different vendor's databases transparent -- some of which have notoriously odd implementations of the SQL spec -- make implementing (3) extremely costly both in $$$ and engineering hours spent. It's not *that* hard. Java tools like Hibernate do it. They still have the sucky performance implied by mapping object graphs to relational databases, but it at least gives you the ability to talk to any SQL database you want to, while still having a core-data like object access. Anybody else looking for an interesting project to work on could well port Hibernate to objective-c. In the case of (3), the assumption would be that -- like with the SQLite database -- Core Data would manage the entire schema of the database on the server. Certainly, that would be useful to a subset of developers, but how many? In studying the problem, I come up with not that many. In almost cases where I have looked at problems that required client/server database access, one of the requirements was to interface with some kind of a reporting engine, web service/server, or something else that wants to go trolling through the data store and, more likely, edit stuff. Nobody wants multi-user access unless they can interface with some 3rd party report engine? Firstly, that's not even nearly true. Tons of companies are buying object databases, and a relatively small group of them actually use them with reporting engines. Secondly an object database has the ability to upload object schemas derived from the object source code to a server without any difficulty. This is easy stuff for an object database. Thirdly, any decent object database can offer a legacy SQL interface that 3rd party reporting engines can talk to. So that brings up (4). (4) is a really really really hard problem to solve. It's not even an issue for object databases, and it's not *that* hard to solve for SQL databases as Hibernate shows. Need a Holiday? Win a $10,000 Holiday of your choice.

Re: Packages vs bundles vs folders etc
I'm surprised that frameworks act like folders in Finder, yet don't conform to public.folder. To be more explicit, I'm writing some code that synchronises two folders. If directory A contains file X and directory B contains file Y, then synchronising them depends on what kind of directory it is. If it is a package, then a resulting package containing files X and Y would be wrong, it could be a corrupt package. Folders should be synchronised and have both X and Y. But I'm not sure about frameworks being neither a folder nor a package. What would users expect? Hmm, I see that bundle, package and folder are the three decendents of public.directory. framework conforms to bundle rather than package and appears in the finder like a folder.

But isn't a framework a package, thus making my statement correct? If a framework is not a package, then what specifically makes a package a package that a framework doesn't fit? Frameworks are not packages. A package is a directory that is presented as a single file to the user, but frameworks are shown as folders and are browsable like other folders. You can check the UTI hierarchy in the UTCoreTypes.h header (try open -h UTCoreTypes.h). Perhaps I should state my question more explicitly. I'm trying to figure out what things should be copied atomically. When a directory is really a bundle (is a bundle == package?), then it must be considered as one unit. If it's just a folder, then the files therein have their own unique reasons for existing. But I'm not sure which API exactly will give me the distinction I want to make. If you copy two folders, Finder reports the total number of items contained within them; but if you copy two applications, Finder reports only two items. Is that the sort of distinction you want to make? If so, I think you're on the right track. On Leopard, I would get the UTI of a file via -[NSWorkspace typeOfFile: error:], and then see if it conforms to kUTTypeFolder via -[NSWorkspace type:fileType conformsToType:(NSString *)kUTTypeFolder]. If it does NOT conform, it should be treated as a single item. If you need Tiger compatibility, you can do the same thing, except you would use LaunchServices functions like LSCopyItemAttribute(). -Peter ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: Packages vs bundles vs folders etc
Would it be fair to say that if a path is a directory, and if the kMDItemContentType != public.folder then NSWorkspace.isFilePackageAtPath would return YES? No. A non-package directory may not even conform to public.folder. For example, volume mount points have the type ID public.volume, which does conform; but frameworks have the type ID public.framework, which does not conform. But isn't a framework a package, thus making my statement correct? If a framework is not a package, then what specifically makes a package a package that a framework doesn't fit? Perhaps I should state my question more explicitly. I'm trying to figure out what things should be copied atomically. When a directory is really a bundle (is a bundle == package?), then it must be considered as one unit. If it's just a folder, then the files therein have their own unique reasons for existing. But I'm not sure which API exactly will give me the distinction I want to make. And conversely if a path is not a directory or the kMDItemContentType == public.folder, then NSWorkspace.isFilePackageAtPath would return NO? I'm pretty sure this is true. All packages are directories, and no package type conforms to public.folder, or ever will. -Peter ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Garbage collector related crash
I've got an object that holds onto a CF ref:
mdref= MDItemCreate(nil, (CFStringRef)path);
[NSMakeCollectable(mdref) autorelease];
I think I'm doing the right thing in the class declaration:
@interface MetadataItem : NSObject {
__strongMDItemRefmdref;
@end
But every now and then:
CFTypeRefres = MDItemCopyAttribute(mdref, (CFStringRef)key);
this makes it crash horribly. It's got to have something to do with garbage
collection, but it seems like I'm doing things right. Any thoughts?

Re: NSLog fixes output, but why?
Should we assume you have eliminated the obvious, that the arguments to NSLog don't have any method calls with side effects? Or are there multiple threads whose timing could be changed by the logging? From: James Maxwell jbmaxw...@rubato-music.com To: Cocoa Dev cocoa-dev@lists.apple.com Sent: Thursday, 19 March, 2009 9:05:31 AM Subject: NSLog fixes output, but why? I've got a really frustrating, and really silly problem. I have some fairly complex machine learning code I'm working on. I've noticed inconsistent output from a particular method. I'm doing some fairly nasty array and matrix stuff, which is all done in C, and I pass the arrays around wrapped in NSData objects. What's really strange is that, in this particular method, if I place an NSLog after calling and unwrapping a particular 2D matrix, then the output is as expected. If I remove the NSLog, the output is incorrect (or at least, unexpected). The system is pretty complex, and involves 4 different classes, so I won't post it here, and obviously I don't expect any magical help. But does anybody have any experience with something this flaky? Whereby literally adding a single NSLog (and thus obviously slowing things down a fair bit) makes the method run correctly?... It's just bizarre, to me. Maybe somebody here has worked their way into a similar corner? Obviously I've done something stupid somewhere, but I don't really know how to go about finding it. It was weird enough to realize that the NSLog could make or break my output - tracking down the actual reason why is just baffling... Everything being done in these classes is basically procedural stuff, so it doesn't seem like timing should dramatically influence the output. But I am doing *lots* of iterations over this data. Does that suggest anything? Any thoughts very much appreciated. cheers, J. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: At what point during loading can NSPersistentDocument fetch?
readFromURL is the appropriate place to start populating the document.
From: Jerry Krinock je...@ieee.org
To: Cocoa Developers cocoa-dev@lists.apple.com
Sent: Tuesday, 17 February, 2009 12:49:44 PM
Subject: At what point during loading can NSPersistentDocument fetch?
My NSPersistentDocument subclass contains a singular managed object which I'd
like to make an observer immediately after the document is loaded. So I
invoked my little fetcher method to get it during -init, after invoking super,
but was surprised to find that the fetch returned empty at this point.
I found the same behavior in Apple's DepartmentAndEmployees [1] sample project
by adding these two methods to the MyDocument implementation:
- (void)logDepartment {
// -department fetches the singular 'department' [2]
NSLog(@ 'Department': %p, [self department]) ;
}
- (id)init {
self = [super init] ;
NSLog(@Fetch during init:) ;
[self logDepartment] ;
NSLog(@Fetched after delay) ;
[self performSelector:@selector(logDepartment)
withObject:nil
afterDelay:0] ;
return self ;
}
Here's the console log I get upon opening an existing document file:
17:06:02.259 Fetch during init:
17:06:02.268'Department': 0x0
17:06:02.269 Fetched after delay
17:06:02.388'Department': 0x1dc730
Besides the fact that it's a kludge, the performSelector:withObject:afterDelay
occurs too late for my purposes. So, I've got one fetch that's too early and
one that's too late. I looked in the debugger's call stack but don't see any
other intermediate method I could legally hook in to.
There are other ways I could set my observer, but I'm quite surprised that
executing a fetch in an initialized NSPersistentDocument doesn't return a
qualified object which is definitely in there, and understanding this might
help me with other issues. Note that executeFetchRequest:error: is happy to
return the incorrect answer of an empty array -- it does not set an NSError.
Can someone please explain at what point, during loading, an
NSPersistentDocument becomes ready to fetch and return correct results?
Thanks as always,
Jerry Krinock
Note: In MyDocument.m, there is an implementation of -initWithType:error: which
inserts a 'Department', but that method only runs for new documents and is not
involved here. I'm trying to fetch a 'Department' from the store/file.
[1] http://developer.apple.com/samplecode/DepartmentAndEmployees/index.html
[2] The following method is right out of the box of MyDocument.m, reproduced
here for convenience.
- (NSManagedObject *)department
{
// Apparently, 'department' is cached as an ivar for efficiency.
if (department != nil)
{
return department;
}
// The remainder of this method, executing a fetch, only executes
// the first time this method is invoked on a document.
NSManagedObjectContext *moc = [self managedObjectContext];
NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
NSError *fetchError = nil;
NSArray *fetchResults;
@try
{
NSEntityDescription *entity = [NSEntityDescription
entityForName:@Department
inManagedObjectContext:moc];
[fetchRequest setEntity:entity];
fetchResults = [moc executeFetchRequest:fetchRequest error:fetchError];
} @finally
{
[fetchRequest release];
}
if ((fetchResults != nil) ([fetchResults count] == 1) (fetchError ==
nil))
{
[self setDepartment:[fetchResults objectAtIndex:0]];
return department;
}
if (fetchError != nil)
{
[self presentError:fetchError];
}
else {
// should present custom error message...
}
return nil;

Re: Network communications help
From what you are saying, I would get the classic intro to UNIX network programming and read the part on sockets: http://www.amazon.com/UNIX-Network-Programming-Richard-Stevens/dp/0139498761 From: gumbo...@mac.com gumbo...@mac.com To: Cocoa-Dev List cocoa-dev@lists.apple.com Sent: Wednesday, 11 February, 2009 12:44:30 PM Subject: Network communications help I currently have a RealBasic application that manages a furnace temperature controller. Using the TCPSocket class in RB the app listens to a port and I can query this application from other computers on the LAN and set parameters of the temperature controller, by passing strings. What I would like to be able to do, is the same thing from my iPhone with a Cocoa application. I have only 3 years experience with Cocoa and none with network comms. Can someone please explain what would be the best way to achieve this and where I should start reading.

FSExchangeObjects / FSReplaceObject
As I understand it, we are supposed to use FSReplaceObject because FSExchangeObjects does not properly retain all meta-data. But it seems like FSReplaceObject is not actually documented. Sure it is mentioned here and there in release notes and so forth, but there is no actual proper API documentation for it. Is this correct? Is it an oversight on Apple's part, or should I read more into it? Make Yahoo!7 your homepage and win a trip to the Quiksilver Pro.

Re: Advanced NSTextView use
That didn't seem to help. I tried overriding selectedRanges, and that makes you delete the whole range when you are clicked in it (good), but nothing seems to help the case of trying to simply backspace from the end of the range. In this case the selected range is not relevant because you are not inside the range yet as far as the existing range, and you can't predict in advance the user intends to backspace into it, and for the same reason, neither is the rangeForUserTextChange. On Feb 3, 2009, at 5:24 PM, Chris Idou wrote: So I want it that if you try and delete any character that is part of a token, it deletes the entire token. So I'm overriding rangeForUserTextChange to return a different range if the current range includes any part of a token. This seems to work if the user tries to type in any part. For example, clicking on the token and pressing space bar or a letter. However, it doesn't work if you press backspace or delete, even though rangeForUserTextChange is still called. I don't think you really want to override that method. Instead override -[NSTextView selectionRangeForProposedRange:granularity:] which should be called for every selection the user makes. ~Martin Make Yahoo!7 your homepage and win a trip to the Quiksilver Pro.

Advanced NSTextView use
I'm trying to use NSTextView so that it has tokens in the text (kind of like NSTokenField). So I want it that if you try and delete any character that is part of a token, it deletes the entire token. So I'm overriding rangeForUserTextChange to return a different range if the current range includes any part of a token. This seems to work if the user tries to type in any part. For example, clicking on the token and pressing space bar or a letter. However, it doesn't work if you press backspace or delete, even though rangeForUserTextChange is still called. In this case it does nothing if the range is zero length, or it does the normal thing and ignores my range, if the user starts off with a range selected. Has anyone got any other ideas how to achieve this? Stay connected to the people that matter most with a smarter inbox.

Triggering NSTextView changes and bindings
I've got an NSTextView whose attributeValue is bound to a core-data object. I've got a menu item which programmatically modifies the NSTextView's contents. The programmatic changes don't trigger a modification to the underlying object unless the user tabs to and exits the NSTextView manually. What is the correct way, when programmatically modifying an NSTextView, to make sure the system propagates changes to underlying bindings?
