Problem with cocoa async sockets

[Samuli Lehtonen]

Hey I started using cocoa sockets sometime ago, so here is the code I got now, 
I am using the echo server example as server which was provided with the class. 
So what I am trying to do is, send a message from the server to client when the 
server receives the message, server gets the message, but client won't get the 
message that server is sending somehow. Only message client gets is the welcome 
message , I don't understand why it won't get the other messages, I've really 
struggled with this now, thanks in advance, I am more than grateful for help!

For the async socket class http://code.google.com/p/cocoaasyncsocket/

I was recommended to use this class for networking on forums, so I used it and 
it seems to be pretty simple expect my problem is pretty weird..

Here is server .m file

#import "AppController.h"
#import "AsyncSocket.h"

#define WELCOME_MSG  0
#define ECHO_MSG 1

#define FORMAT(format, ...) [NSString stringWithFormat:(format), ##__VA_ARGS__]

@interface AppController (PrivateAPI)
- (void)logError:(NSString *)msg;
- (void)logInfo:(NSString *)msg;
- (void)logMessage:(NSString *)msg;
@end


@implementation AppController

- (id)init
{
if(self = [super init])
{
listenSocket = [[AsyncSocket alloc] initWithDelegate:self];
connectedSockets = [[NSMutableArray alloc] initWithCapacity:1];

isRunning = NO;
}
return self;
}

- (void)awakeFromNib
{
[logView setString:@""];
}

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
NSLog(@"Ready");

// Advanced options - enable the socket to contine operations even 
during modal dialogs, and menu browsing
[listenSocket setRunLoopModes:[NSArray 
arrayWithObject:NSRunLoopCommonModes]];
}

- (void)scrollToBottom
{
NSScrollView *scrollView = [logView enclosingScrollView];
NSPoint newScrollOrigin;

if ([[scrollView documentView] isFlipped])
newScrollOrigin = NSMakePoint(0.0, NSMaxY([[scrollView 
documentView] frame]));
else
newScrollOrigin = NSMakePoint(0.0, 0.0);

[[scrollView documentView] scrollPoint:newScrollOrigin];
}

- (void)logError:(NSString *)msg
{
NSString *paragraph = [NSString stringWithFormat:@"%...@\n", msg];

NSMutableDictionary *attributes = [NSMutableDictionary 
dictionaryWithCapacity:1];
[attributes setObject:[NSColor redColor] 
forKey:NSForegroundColorAttributeName];

NSAttributedString *as = [[NSAttributedString alloc] 
initWithString:paragraph attributes:attributes];
[as autorelease];

[[logView textStorage] appendAttributedString:as];
[self scrollToBottom];
}

- (void)logInfo:(NSString *)msg
{
NSString *paragraph = [NSString stringWithFormat:@"%...@\n", msg];

NSMutableDictionary *attributes = [NSMutableDictionary 
dictionaryWithCapacity:1];
[attributes setObject:[NSColor purpleColor] 
forKey:NSForegroundColorAttributeName];

NSAttributedString *as = [[NSAttributedString alloc]

[as autorelease];

[[logView textStorage] appendAttributedString:as];

}

}

- (IBAction)startStop:(id)sender
{
if(!isRunning)
{
int port = [portField intValue];

if(port < 0 || port > 65535)
{
port = 0;
}

NSError *error = nil;
if(![listenSocket acceptOnPort:port error:&error])
{
[self logError:FORMAT(@"Error starting server: %@", 
error)];
return;
}

[self logInfo:FORMAT(@"Echo server started on port %hu", 
[listenSocket localPort])];
isRunning = YES;

[portField setEnabled:NO];
[startStopButton setTitle:@"Stop"];
}
else

Privileged file deletion using BetterAuthSample (factored application) : secure?

[Michaël Fortin]

Hi everyone, first mail here.

I am making a small app which needs to delete some files that require 
privileged access (log files that the user doesn't have permissions to modify).

Currently I am deleting files using NSTask with rm or srm.

I looked at the Security Services documentation and it seems to me that the 
"factored application" method is the most secure way to proceed with 
authentication to allow deletion of protected files. After further digging I 
found the BetterAuthSample code that (from what I've seen) is the recommended 
way to implement the factored application approach.

My question is as follows: Is the BAS approach secure in this particular 
context?

Let me explain my understanding of how BAS works and why I think it might be 
insecure in this case. Please correct me if I'm wrong.

My understanding is that the Helper Tool implements a protocol allowing it to 
respond to application commands. In my case I would have a command which takes 
a file path and secure deletion mode as input. This helper tool is installed in 
a privileged directory which grants the tool the right to perform privileged 
operations. *after the initial installation authentication, the tool is 
installed in the privileged folder and it always possesses the right to delete 
privileged files without further authentication*. So what that would mean is 
that any application could potentially pass a file and secure deletion mode and 
have it deleted.

I'm sure there's something wrong in that reasoning because it doesn't seem 
logical that any app could use the tool once it's installed, but by reading the 
documentation I'm not sure exactly if and how the helper tool makes sure it's 
only used by my application.

Thanks in advance for any clarification.

Regards,
Michaël Fortin

Disable exceptions in Objective-C++ files when building for x86_64?

[James Dolan]

Forgive me if this is the wrong list for this question, but I have the
strangest problem.

I just noticed that '-fno-exceptions' has no effect on .m or .mm
files, but only when '-arch x86_64' is set. In other words,
__EXCEPTIONS is raised when it shouldn't be.

It should be easy for anyone to repro... just run the following
commands in Terminal.

exceptions still enabled!
  gcc -fno-exceptions -arch x86_64 -dM -E -x objective-c++ - <<<'' |
grep __EXCEPTIONS

exceptions not enabled.
  gcc -fno-exceptions -arch i386 -dM -E -x objective-c++ - <<<'' |
grep __EXCEPTIONS
  gcc -fno-exceptions -arch x86_64 -dM -E -x c++ - <<<'' | grep __EXCEPTIONS

Highlight Text like with FIne

[Brad Stone]

I want to highlight different substrings contained in controls in a window (two 
different comboBoxes for example) programmatically when the user is searching 
for a subString.  I can do this for one comboBox but not both simultaneously.  
Here's one.

NSString *s = [titleComboBox stringValue];
NSRange r = [s rangeOfString:searchText options:NSCaseInsensitiveSearch 
range:NSMakeRange(0, [s length])];
[titleComboBox selectText:w];   
if (r.location != NSNotFound) {
// this is needed to select the substring
NSText *textEditor = [w fieldEditor:YES forObject:titleComboBox];
[textEditor setSelectedRange:r];
}

But this only highlights the text in the titleComboBox.  If I then repeat this 
to highlight the  text in the categoryComboBox by repeating the code, 
titleComboBox gets deselected and categoryComboBox gets selected.  I want to 
highlight them both simultaneously.  I'd also rather use the big yellow 
highlight like with the find panel (but that's later).

Is this possible? 

Thanks___

Oh, you probably want to go left to right, not top to bottom.

Nevertheless, it's one function call.

NSDrawThreePartImage looks like it should be very easy in this case.  In
fact, it looks like you do have a separate top image (though you could pass
nil if you didn't).

Quincey may be right that drawing the image directly is the easier approach, 
but it /is/ possible to change the offset of a pattern image by altering the 
graphics context's pattern phase.  Before you draw:

CGFloat offset = ;

CGContextSetPatternPhase((CGContextRef)[[NSGraphicsContext currentContext] 
graphicsPort], CGSizeMake(0, offset));
