Re: Need localization-proof method of transporting dates.
On Apr 4, 2009, at 2:01 PM, Graham Cox wrote: My app encodes expiry dates for demo versions, etc. One problem I've had occasional reports of is that the expiry is prematurely detected, and it seems to be on systems with system language set other than English. I need to store and check the dates in a way that is not sensitive to this. I thought I was, yet the reports persist. Here's what I'm doing: The stored date originally comes from a NSDatePicker control, textual with stepper. I retrieve the date using its -dateValue method. The date, along with other data, is digitally signed with a SHA-1 hash, which in turn is based on the object's -hash method. As far as I could tell, the -hash method returns a value that is sensitive to the actual stored date, but not to the date localization on the system. At runtime, the date is recovered and verified by rehashing and comparing the hash, then the date value is simply compared to see if the current date is before or after it using [[NSDate date] timeIntervalSinceDate:expiryDate] (if negative, hasn't expired). Can anyone spot any problem with this approach? Note that the SHA-1 check appears to pass OK - it's the date comparison that seems to be wrong. Unfortunately I can't reproduce the bug locally so I'm relying on reports from relatively non-technical testers who aren't able to give me much to go on. --Graham I suggest encoding your dates as strings, in standard Iso Text Format (-mm-ss) --- See the amazing new SF reel: Invasion of the man eating cucumbers from outer space.

You can write your implementation file in Objective C++ , and use
std::map
Then write your header like this:
#ifdef __cplusplus
#include
#endif
@interface MyClass: NSObject
{
#ifdef __cplusplus
std::map * mymap; //All data pointers have same size,
#else
void * mymap;
#endif
}
@end
Then in your implementation file initialize your pointer:
mymap = new std::map
and use it like this:
(*mymap) [integervalue] = someid;

look for your disk image and its current mount location. Then compare
that to your bundles location.

Unfortunately, the DiskImages framework is private (no headers)
Getting the output of hdiutil is a little awkward since the NSDictionary

This last trick is not useful for telling wether the user is running
the app directly from the download
dmg.
Testing wether the Volume containing the app is removeable will match
for ANY volume except the boot volume.

If a disk image it mounted a second time (can happen in a few ways) it
won't be at /Volumes/Mother/... but at /Volumes/Mounter 1/... Also you
can mount disk images in location other then under /Volumes/...
It will be /Volumes/Mother 1/... I've tested.
This can be handled by using a regexp class for the matching instead
of a simple
equality test.
Also, while it's possible to mount a disk image at other places than
under Volumes,
that won't happen when doubleclicking a disk image or it being mounted

You can do that by just redirect standard error to a file. Since
each process has their own set of file descriptors it will only
affect your application.
int fd = creat ("/Users/marcus/my_log", S_IRUSR | S_IWUSR | S_IRGRP

The specified method don't work. The default console log don't get a
copy this way.
A similar methods works if I forks, and pipes standard error into the
tee command.
I had really hoped there would be a method to set up the standard
error fd to
echo it's data to multiple file descriptors in my process.

On 31 okt 2008, at 02.30, Peter N Lewis wrote: AI am a newbie to the cocoa world (PC -> Mac switcher). I have a fair amount of experience coding in C and C++ and I am just getting into Obj C now. Right now I am trying to learn the language idioms and patterns in the Obj C world, specifically, when do you find yourself mixing C++ code with your Obj C code in your project? How often do you do that? What's the pros and cons of doing that? Keyboard Maestro was written entirely in in C++/Carbon. There were a couple useful Cocoa classes, so I mixed them in (eg Cocoa has a method to expand ~ in file paths). When it was time to start moving to Cocoa more seriously, I just turned the compiler on to Objective C++ for the entire project, recompiled and there was essentially no change (no size or speed changes were noticeable). Then I just started writing Cocoa objects for various UI. Many of my Cocoa objects have a C interface to create them and a C++ pointer as a "delegate" to interface with. About the biggest issue is that you cannot have C++ objects in an Objective C object (their constructors and destructors wont be called). You can happily have pointers to C++ objects though, you just have to manage the creation and destruction yourself (which can be a bit of a pain in Cocoa as there is no single constructor place - but fortunately (or not) you wont be using Garbage Collection any time soon so at least dealloc is a single point for removal in most cases). You can invoke the constructors and destructors yourself, using placement new. Also, supporting GC is no big deal: simnply add a finalize method to destroy c++ objects. You also need tor read the Apple docs on mixing Carbon & Cocoa. Introduction to Carbon-Cocoa Integration Guide <http://developer.apple.com/documentation/Cocoa/Conceptual/CarbonCocoaDoc/CarbonCocoaDoc.html > But basically, "it just works". There isn't much pain with simply using Objective C++ and writing parts of your code in Cocoa. Enjoy, Peter. -- Keyboard Maestro 3 Now Available! Now With Status Menu triggers!

Re: How to check the number of pending events in the application event queue?
On 27 okt 2008, at 13.54, Oleg Krupnov wrote: In my app I'd like to perform some background task without affecting the responsiveness of the UI. To avoid multi-threading, I just postpone the task to a moment when the user becomes and stays idle for a certain time. I call NSObject's performSelector: afterDelay: and then use CGEventSourceSecondsSinceLastEventType to check if the idleness period has elapsed. If not, I wait again the remaining time, else I begin performing the task. Also, because the background task is quite lengthy, I make the task poll periodically if the user has become active during the task, and in this case postpone the task's continuation again until the user becomes idle again. This solution seems to be quite good, but for one question : how do I check if there are pending events in the application's queue right at the moment of timer firing? This would work as a double-check that there are no pending tasks for the application (e.g. other periodic events of the app) that would always have to be done before the low-priority background task. I tried NSApplication's nextEventMatchingMask, but it blocks execution if there are no events, whereas I'd like it to return nil.

One of the ways that it's broken is that it is *impossible* to correctly use it without a subprocess which will cooperate with you. The reason for this is that you *must* use wait4 or waitpid to reap the zombie that will be created when the subprocess terminates, but AEWP provides *no* way to get the pid. (You cannot use wait or wait3 because those could NOPE. As soon as the App terminates, any unreaped subprocess will become a child of, and finally reaped by launchd end up inadvertently reaping a child process spawned by a library you're using.) So your subprocess must have a way to communicate its pid back to the parent, and do so very early before it does anything that could make it crash or otherwise terminate. Correct use of AEWP is extremely weird and un-fun. I definitely recommend finding some of Apple's sample code on the subject, and then adapting it to do what you need, rather than trying to figure out how to use it on your own.

For another it will fail if the new process would exceed the user's process limit, a limit which tends to be much lower than most other resource limits and thus much easier to encounter in realistic situations. Firstly you can just increase the soft limit. Hard limits on Mac OS X is very generous. Secondly it would fail because maximum number of processes have been reached, you can simply retry later. I have never had a process break because it has reached the maximum allowed cpu-time, except in situations where I've deliberately set it very low, For the original problem, I'd recommend using something like LSCopyApplicationURLsForURL() if it's at all possible. Of course maybe you have data that isn't good for that, but if you can use it then that's the way to go. If you must search the disk, use Spotlight if you can. It will be vastly faster than anything else. The downside is that it won't work if indexing is disabled or if the desired application is in an excluded directory. Using Spotlight to search for applications won't work, because some open-source packages install apps in directories that's not searched by spotlight, For example - the default install path for Qt is in directory /usr/local/Trolltech/Qt- If you must search the whole disk without Spotlight, use NSDirectoryEnumerator.
