libs-base's Introduction

GNUstep Base Library

The GNUstep Base Library is a library of general-purpose, non-graphical Objective C objects. For example, it includes classes for strings, object collections, byte streams, typed coders, invocations, notifications, notification dispatchers, moments in time, network ports, remote object messaging support (distributed objects), and event loops.

It provides functionality that aims to implement the non-graphical portion of the Apple's Cocoa frameworks (the Foundation library) which came from the OpenStep standard.

Initial reading

The file NEWS has the library's feature history.

The files INSTALL or GNUstep-HOWTO (from the web site) gives instructions for installing the library.

libs-base's Issues

It is currently not possible to use non-strings as keys...

Steps to recreate...

Create an NSArray
Create an NSDictionary
use the NSArray as a key for something in the NSDictionary.

Result: you will get an exception complaining about hasPrefix: (this is called in NSDictionary.m) to remove "@" from the string...
EXPECTED: This should work.

Please see my example test here: https://github.com/gcasa/NSDictionary_test

build failed with ARC(clang -fobjc-arc) option

checking whether objc really works... no
I don't seem to be able to use your Objective-C compiler to produce
working binaries!  Please check your Objective-C compiler installation.
If you are using gcc-3.x make sure that your compiler's libgcc_s and libobjc
can be found by the dynamic linker - usually that requires you to play
with LD_LIBRARY_PATH or /etc/ld.so.conf.
Please refer to your compiler installation instructions for more help.

how to support ARC in GNUstep base library?

NSTimer with blocks doesn’t work (but with @selector works)

Hi,

When I use NSTimer with a @selector it works fine, but when I use it with a block it doesn’t work:

  self.nstimer1 = [NSTimer scheduledTimerWithTimeInterval:1.0
                                                  repeats:YES
                                                   block:^(NSTimer* t) {
                                                           NSLog(@"NSTimer1");
                                                         }];
  self.nstimer2 = [NSTimer scheduledTimerWithTimeInterval:1.0
                                                   target:self
                                                 selector:@selector(timer2callback:)
                                                 userInfo:nil
                                                  repeats:YES];

    NSLog(@"NSTimer1 is %@", self.nstimer1);
    NSLog(@"NSTimer2 is %@", self.nstimer2);
}

-(void)timer2callback:(NSTimer*)timer {
    NSLog(@"NSTimer2");
}

Note that the block that should be called by NSTimer1 is not called (and, in fact, is printed out as (null)).

[NSCharacterSet invertedSet] doesn't contain all the characters it should

NSCharacterSet *everythingExceptNewlines = [[NSCharacterSet newlineCharacterSet] invertedSet];
BOOL a = [everythingExceptNewlines characterIsMember:0x0061];
BOOL ö = [everythingExceptNewlines characterIsMember:0x00f6];

a is YES
ö is NO

Both BOOLs should be YES.
(When I tested in January this worked as expected)

WSAStartup() should not be called from DllMain

Running our Windows app using GNUstep Base through Application Verifier leads to the following warning:

VERIFIER STOP 000000000000E100: pid 0x3E40: Illegal networking API called from DllMain 

	00007FFEC14203B0 : Networking function being called from DllMain
	000001F4678A3FCC : Name of Dll making invalid call if not NULL
	0000000000000000 : Not used
	0000000000000000 : Not used

This seems to be caused by WSAStartup() being called from DllMain in gnustep_base_socket_init().

The WSAStartup() documentation says:

The WSAStartup function typically leads to protocol-specific helper DLLs being loaded. As a result, the WSAStartup function should not be called from the DllMain function in a application DLL. This can potentially cause deadlocks. For more information, please see the DLL Main Function.

Given that gnustep_base_socket_init() is also called from +[NSObject initialize], do we actually need to also call it from DllMain?

NSCalendar rangeOfUnit:inUnit:forDate: not implemented

Hello, I've a different behavior of NSCalendar that makes my little App to work on OS X 10.10, 10.6.8, but not on GNUstep.

I wrote the App on 10.10, then ported on 10.6.8 to make compatible GNUstep nibs/xibs, then ported on GNUstep.

The problem seems to come from the line 59 in AppDelegate.m, when trying to calculate an NSRange:

NSRange range = [gregorian rangeOfUnit:NSDayCalendarUnit inUnit:NSMonthCalendarUnit forDate:      [gregorian dateFromComponents:components]];
monthDays = range.length;
NSLog(@"Numbers of Days %ld", monthDays);

From the NSLog I can see that monthDays is "0", insted on OS X is 28 (for february, 31 for Jan, and so on).

What I wrong?

You can look the code on github:

https://github.com/AlessandroSangiuliano/Calendar

In the OSX directory there is the OS X version of the App.

Best Regards,

Alex.

P.S: I sent this mail two times on the discuXX-gnustXX mailing list, one yesterday and one this morning, but seems my mails are no more accepted by the server for some reason.

NSFileManager _copyFile:toFile:handler should handle source file size change gracefully

An application of mine recently went into an infinite loop when it called NSFileManager's copyPath method. The problem was that the source file was modified by a different process during the copy. The NSFileManager code contains a loop up to the size of the source file (currently at line 2821), where the loop counter is incremented by the number of bytes read from the source file and the file size is computed at the start of the copy. There is a race condition here: if the file gets smaller during the copy, then read will hit EOF before the loop counter reaches the previous size, and the read will keep returning 0, resulting in an infinite loop.

I suggest that if the read operation returns 0 more than once in the loop, the method should throw an exception stating that the source file was possibly modified.

Please add base/Resources/Languages file for various languages in Switzerland locale

we don't have EUR, but CHF, and four languages Swiss German (no https://de.wikipedia.org/wiki/%C3%9F, but it's ss always in Switzerland German), Swiss French, and Swiss Italian (the fourth is minor).

What should it be called for Switzerland? The currency is the same for all four official languages. One file for Switzerland would make sense.

Error using __block storage type modifier due to NSXPCConnection.h undefining it

With the recent change in NSXPCConnection I am no longer able to use the __block storage type modifier on variable definitions, because the change is undefining the __block built-in.

When I remove the #ifdef/#undef in NSXPCConnection.h, I get the following output showing the original built-in definition:

NSXPCConnection.h:41:9: warning: '__block' macro redefined [-Wmacro-redefined]
#define __block __gs_unistd_block
        ^
<built-in>:66:9: note: previous definition is here
#define __block __attribute__((__blocks__(byref)))

This is using the Android toolchain with the 2.0 runtime and blocks.

Tests don't set rpath

The GNUstep Base test suite doesn't set the rpath to point to the built library. This means that you need to juggle LD_LIBRARY_PATH directives if you want to run the tests against the just-build -base, without having to install it.

Calling 'mutableBytes' on NSMutableData

Calling 'mutableBytes' on NSMutableData fails with the following message:

NSInvalidArgumentException, reason: NSDataStatic(instance) does not recognize mutableBytes

The following sample reproduces the problem:

#import <Foundation/Foundation.h>

int main( int argc, const char* argv[] )
{

	char* pStore = malloc( 1024 );

	NSMutableData* dataStore =
		[NSMutableData dataWithBytesNoCopy:pStore
						length:1024
					freeWhenDone:YES];

    // getting bytes.
	char* theData = [dataStore mutableBytes];

	return 0;
}

do these just need updating expected test results?

retain count overflow

After running for about 12 hours, my program dies with this uncaught exception:

Uncaught exception NSInternalInconsistencyException, reason: NSIncrementExtraRefCount() asked to increment too far for <NSIntNumber: 0xefd560> - 1

I searched around my code for any extra retains but couldn't find the problem, plus the odd thing is that while I use NSNumber, I'm using doubles and not integers. Anyways, I ran the program so I could get a stack trace when the exception was raised.

Note that none of this is my own code, so it seems to be a bug in base library. I browsed the code but I'm not sure if this is a bug in NSOperation or in the KeyValueObserver.

My code uses NSOperation and NSOperationQueue excessively to parallelize a bunch of compute-intensive calculations. I don't free the NSOperationQueue until the end of the program, here is the inner loop that creates the NSOperation and adds to the queue. This code snippet is also about 3 for loops deep so I eventually run enough operations to hit the retain count.

        for (i = 0; i < numOfObservations; ++i) {
            // snip other stuff
            id io = [[[NSInvocationOperation alloc] initWithTarget: optJob selector: @selector(doVariableOptimize) object: nil] autorelease];
	    [operationQueue addOperation: io];
        }
        [operationQueue waitUntilAllOperationsAreFinished];

I use NSAutoreleasePools at every for loop level because the data I'm processing is quite large, and I watched the retain counts with -autoreleaseCount as part of tracking this down but everything looks fine. I'm using the latest libs-base code from the repository, and this same code runs fine Mac OSX.

I imagine a simple test case that does > 0xfffffe NSOperations might reproduce the bug, but I'm wondering if anybody familiar with the code might have an idea.

Configure failure during check for whether "objc really works"

Hello,

I'm running into an error while building libs-base under Alpine linux using Clang 10. (Libobjc2 installed fine.) During ./configure for libs-base, I get the following error: checking whether objc really works... no

But there's no further indication on what the problem is. Can anyone provide insight?

Complete logs attached.

Thank you,
Patryk

I don't seem to be able to use your Objective-C compiler to produce
working binaries!  Please check your Objective-C compiler installation.
If you are using gcc-3.x make sure that your compiler's libgcc_s and libobjc
can be found by the dynamic linker - usually that requires you to play
with LD_LIBRARY_PATH or /etc/ld.so.conf.
Please refer to your compiler installation instructions for more help.

Undefined reference to 'CFStringConvertEncodingToNSStringEncoding'

I am trying to work with CHCSVParser (https://github.com/davedelong/CHCSVParser/tree/master/CHCSVParser). GNUstep can't compile a file that is referencing CFStringConvertEncodingToNSStringEncoding(), failing with the error

"Undefined reference to 'CFStringConvertEncodingToNSStringEncoding'"

Build is broken on Ubuntu 16.04

Was building fine recently (1-2 months ago).
Using the script from http://wiki.gnustep.org/index.php/GNUstep_under_Ubuntu_Linux#16.04.2C_16.10.2C_.26_17.04

Trying to build with earlier commits now seems to be also broken, so either I'm doing something wrong (but the script definitely worked before) or one of package updates broke it. Not sure how to deal with this.

NSJSONSerialization serializes all integral NSNumbers as signed numbers

Per https://github.com/gnustep/libs-base/blob/master/Source/NSJSONSerialization.m#L944:

  else if ([obj isKindOfClass: NSNumberClass])
    {
      const char        *t = [obj objCType];

      if (strchr("cCsSiIlLqQ", *t) != 0)
        {
          long long     i = [(NSNumber*)obj longLongValue];

          [output appendFormat: @"%lld", i];
        }
      else
        {
          [output appendFormat: @"%.17g", [(NSNumber*)obj doubleValue]];
        }
    }

Regardless of whether the NSNumber has been created a signed or unsigned variant of numberWith(sign)(size), it'll be JSON-serialized as an unsigned number. This is a problem, because negative numbers can be equal to positive numbers mostly only in C-family languages, and JSON interops with much higher-level languages.

Deadlock in NSOperationQueue

If -[NSThread detachNewThread...] fails (due, say, to running out of memory), it raises an exception. -[NSOperationQueue _execute] contains this snippet:

          [internal->cond lock];
          pending = [internal->starting count];
          [internal->starting addObject: op];

          /* Create a new thread if all existing threads are busy and                                                               
           * we haven't reached the pool limit.                                                                                     
           */
          if (0 == internal->threadCount
            || (pending > 0 && internal->threadCount < POOL))
            {
              internal->threadCount++;
              [NSThread detachNewThreadSelector: @selector(_thread)
                                       toTarget: self
                                     withObject: nil];
            }
          /* Tell the thread pool that there is an operation to start.                                                              
           */
          [internal->cond unlockWithCondition: 1];

Clearly, if detachNewThread... raises an exception, internal->cond is left locked. Hilarity ensues:

dispatch cannot be used

Os:Centos 6.7
Is there any way to using dispatch on centos or change os to ubuntu or freebsd!

thanks!

GNUstep.conf in wrong location on FreeBSD

Guessing this is the right repository to report this issue.

GNUstep.conf is located in /usr/local/GNUstep/ when installed via FreeBSD packages. It seems likely that this should actually be /usr/local/etc/GNUstep/

NSOrderedSet -- Add hashing mechanism to speed up lookup

fredkiefer 2 days ago Member
This method could be moved to the abstract class.

@fredkiefer
fredkiefer 20 hours ago Member
Or rather not. We should make this method really fast by using a hashing structure in addition to the array. This is the main difference between this class and NSArray, so this may actually be the most important part of the class.

@gcasa
gcasa 18 hours ago Author Member
Okay, cool.

Since implementing the hashing structure is more involved I'm going to submit a change request for it.

NSStream should not require subclasses to implement streamError

Apple's documentation says the only methods required to be implemented by subclasses are:

NSInputStream: read:maxLength:, getBuffer:length:, and hasBytesAvailable
NSOutputStream: write:maxLength: and hasSpaceAvailable

streamError is not on either of these lists, so NSStream should provide a stub that returns nil.

Please use pkg-config to detect icu

icu-config has been deprecated by its upstream developers for some years now. In icu 63.1, icu-config is optional to install, but installed by default. In the next version, icu-config will no longer be installed by default.

The developers recommend downstream packages use pkg-config to detect the icu libraries.

Please let me know if you need any help with this change.

NSURL -resourceDataUsingCache: seems to ignore the flag...

NSURL -resourceDataUsingCache: seems to ignore the flag... is this on purpose?

Unable to change NSFileModificationDate to '2019-06-28 19:35:09 -0400' - Not a directory, English.lproj/MainMenu.nib

NSFileManager method:

		 toPath: (NSString*)dst
		  error: (NSError**)error

Is failing to copy nib files in buildtool because of this error...

2020-07-09 01:31:59.997 buildtool[1221:1221] ERROR: Unable to change NSFileModificationDate to '2019-06-28 19:35:09 -0400' - Not a directory, English.lproj/MainMenu.nib -> build/Bean/Products/Bean.app/Resources/English.lproj/MainMenu.nib

I don't believe that this should be preventing the copy operation to finish. Updating the creation date should not be a critical failure.

CI currently broken on NSURLConnection tests

It looks like ccb8594 has broken the build on CI. At least build starts to fail there, and changes to NSURLProtocol might be related to breaking NSURLConnection tests.

Perhaps something to do with the use of protocol syntax? All of clang and gcc buids seem to be failing on NSURLConnection related tests.

base/NSURLConnection/basic.m:
Failed file:     basic.m aborted without running all tests!
base/NSURLConnection/test01.m:
Failed file:     test01.m aborted without running all tests!
base/NSURLConnection/test04.m:
Failed file:     test04.m aborted without running all tests!
base/NSURLConnection/test05.m:
Failed file:     test05.m aborted without running all tests!

Unfortunately I cannot see more detailed output.

I suppose it's best to assign to @rfm as this was his push.

Support gnustep-2.0 ABI in GSPrivateSymbolPath()

GSPrivateSymbolPath currently maps from classes into defining objects by looking for the __objc_class_name_* symbol. This fails with the gnustep-2.0 ABI, which uses _OBJC_CLASS as the prefix.

NSDictionary keysSortedByValueUsingComparator: does not return keys sorted by the corresponding value in the dictionary

NSDictionary keysSortedByValueUsingComparator: appears to have a bug. It does not actually return the keys sorted by the values. (Instead it appears to be sorting the keys based on their own value rather than the value each maps to in the dictionary...)

A test illustrating the failure is provided as part of #68

For reference here is what Apple's docs say
"keysSortedByValueUsingComparator:
Returns an array of the dictionary’s keys, in the order they would be in if the dictionary were sorted by its values using a given comparator block."

objc exception atExit handler: NSDecrementExtraRefCount

Hello,

I am trying to use ObjC with ARC, libdispatch and blocks on Linux. I believe I am seeing a problem where the atExit of NSUserDefaults is decrementing a reference count below 0. I have tried to reduce the problem to a very small example.

Last year, using Ubuntu 12.04 and clang 3.4 I built and used ObjC and libobjc2 successfully. I am trying to recreate a similar working environment on Debian 8. I installed clang from 'apt-get'. It is version 3.5.

Two days ago, I received information to use commit 6b28593 in libobjc2 to get past an ivar aliasing problem. That commit fixed the problem I reported there regarding libobjc2.

Here is the program that illustrates the GNUstepBase problem. The arrays are there to illustrate that gnustep-base seems to be working, and that ARC is releasing the arrays. I've added a dispatch timer that waits for 5 seconds and then exits the program. On my old installation, this use of exit() cleanly closes down the program.

The recipe I've followed for building libobjc2 and libdispatch are as follows. I've repeated this a few times.

export LD_LIBRARY_PATH=/usr/local/lib:/usr/GNUstep/Local/Library/Libraries

Now build the program. Note the use of the -DOS_OBJECT_USE_OBJC=0 - this seems to be necessary to inform the dispatch headers.

Any ideas or pointers are appreciated.

pldes and friends should have a NSPropertyListGNUstepFormat output option

pldes and related utilities currently perform plist dumps by using the description family of properties on the parsed object. Doing so causes information loss for NSValue and NSDate entries, a scenario that NSPropertyListGNUstepFormat was exactly invented for. It is my opinion that if a utility is described as a tool for "format conversion", they should get an option for trying to not lose too much data.

There are many screenfuls of this output. The generated documentation is lacking in actual classes being documented:

I have no good theory about what is broken; the lines affected seem rather standard to me. However, I think it's only polite towards the users to consider this a release blocker.

NSURLResponse does not allow for multiple Set-Cookie headers in the same response

According to RFC6265 response headers can contain multiple Set-Cookie headers. However, the [NSURLResponse _setHeaders:] method converts the array of headers into a dictionary keyed by header name. This results in only getting the latest cookie when the server tries to set multiple cookies in the same response.

Perhaps, if it's valid, it would be possible to fold multiple Set-Cookie headers, RFC2956 mentions folding multiple Set-Cookie headers, but RFC6256 says they should not be folded...

And is there a current workaround for this? Perhaps some method I'm missing that would allow me to get the full array of headers having made a request, not just the NSDictionary.

Thanks!

-[NSArray indexOfObject: inSortedRange: options:0 usingComparator:] raises range exception when object is not found

The following very simple program raises an index error:

#import <Foundation/Foundation.h>

int main() {
        NSArray* ints = @[@(1), @(2)];
        [ints indexOfObject:@(3) inSortedRange:NSMakeRange(0,2) options:0 usingComparator:^(id left, id right) { 
                int diff = [left intValue] - [right intValue];
                if (diff < 0) return NSOrderedAscending;
                if (diff > 0) return NSOrderedDescending;
                return NSOrderedSame;
        }];
}

$ ./obj/index
./obj/index: Uncaught exception NSRangeException, reason: Index 2 is out of range 2 (in 'objectAtIndex:')

It seems to happen because NSArray.m:1211 assumes that GSLeftInsertionPointForKeyInSortedRange returns an index within the collection.

Richard just changed the behaviour of this method in the main branch. You may need to have a look at that change.

I can look at that. I'm trying to make the method more automated (so people mostly don't need to override it in subclasses), and while the current code in the main branch works I'm not yet finished with it (I'm wondering whether to use malloc_usable_size() on non-object pointer ivars in the default code).

NSTask fails to show text message on command prompt

The issue may be unrelated to NSTask itself but come from the command prompt environment. Here is a small sample that repeats the issue:

#import <Foundation/Foundation.h>


int main(void)
{
    NSAutoreleasePool *pool = \
        [[NSAutoreleasePool alloc] init];
    if (!pool)
        return 1;

    NSTask *task = nil;

    NSString *command = \
        [NSString stringWithString: @"cmd.exe"];

    NSArray *arguments = \
        [NSArray arrayWithObjects: \
            @"/c", @"dir", nil];

    task = [[[NSTask alloc] init] autorelease];
    if (!task)
        goto ERROR_MAIN;

    [task setLaunchPath: command];
    [task setArguments: arguments];

    [task launch];

    /* Block current program. */
    [task waitUntilExit];

    int status = [task terminationStatus];

    [pool drain];

    return status;

ERROR_MAIN:
    [pool drain];

    return 1;
}

On MinGW console of MSYS2, the program successes to show the message emitted by dir. Nevertheless, on command prompt, the same program fails to show the message emitted by dir.

-[NSURL URLByAppendingPathComponent:] only works if URL had a path component to begin with

#include <Foundation/Foundation.h>

int main() {
        NSURL* url = [NSURL URLWithString:@"http://www.example.com"];
        NSURL* next = [url URLByAppendingPathComponent:@"example_path"];
        NSLog(@"%@", next);
}

This outputs "http://www.example.com/". Using this base URL instead:

NSURL* url = [NSURL URLWithString:@"http://www.example.com/"];

(notice the trailing forward slash)

then we actually get "http://www.example.com/example_path".

Apple's implementation returns "http://www.example.com/example_path" for both.

Windows 2000 experience.

Hello.

Stated that the previous version works on Windows 2000

http://www.gnustep.org/windows/installer.html

I managed build current release version gnustep on Windows 2000.

https://imgur.com/a/0yIvjoj

(gnustep-make-2.7.0
gnustep-base-1.26.0
gnustep-gui-0.27.0
gnustep-back-0.27.0
plugins-themes-WinUXTheme-master)

I only had a couple of problems.

1 ICU 50 didn't support Windows 2000.

ICU 50 uses GetGeoInfoW
https://github.com/unicode-org/icu/blob/4509ab7d96fe996d528ce5db650a031cefee7435/icu4c/source/common/wintz.cpp#L71
GetGeoInfoW : Minimum supported client Windows XP
https://msdn.microsoft.com/en-us/windows/desktop/dd318099?f=255&MSPPError=-2147217396
ICU 49 works.
I changed only two lines in gnustep source.
instead 949 and 950 lines

libs-base/Source/NSDateFormatter.m

Line 949 in ea95ff1

timeStyle = pat ? UDAT_PATTERN : NSToUDateFormatStyle (internal->_timeStyle);

libs-base/Source/NSDateFormatter.m

Line 950 in ea95ff1

dateStyle = pat ? UDAT_PATTERN : NSToUDateFormatStyle (internal->_dateStyle);

I used:

timeStyle = NSToUDateFormatStyle (internal->_timeStyle);
dateStyle = NSToUDateFormatStyle (internal->_dateStyle);

2 Configure issues

I changed configure here and in libs-gui to work with icu 49.
instead of harcoded libs (https://github.com/gnustep/libs-gui/blob/master/configure.ac#L464) I used pkg-config

3 Themes didn't work on Windows 2000

The issue because Windows 2000 doesn't have uxtheme.dll.
But I found the site: https://kzar.co.uk/blog/2010/10/06/fixing-spotify-uxtheme.dll-error-on-windows-2000/
It works with the dll.

Give us feedback! Tell us what you like; tell us what you think could be better.

Thank you, few toolkits work in 2019 on Windows 2000.

I saw that: https://groups.google.com/forum/#!topic/gnu.gnustep.discuss/d4CSDyz29Rk

I don’t know if ifdef is needed in your code, maybe such a note will be enough for those who need to build gnustep to work on Windows 2000

I built gnustep with support Windows 2000 just for fun, not for real need.

Performance improvements in NSOrderedSet

RFM Commented:

I have to apologise for taking so very long before I had a chance to look at this issue at all. even now I've really only had a quick look, concentrating on the concrete implementation. I also had a quick skim of the Apple documentation.
One paragraph from the intro of the documentation struck me:

You can use ordered sets as an alternative to arrays when the order of elements is important and performance in testing whether an object is contained in the set is a consideration—testing for membership of an array is slower than testing for membership of a set.

This suggests to me that the current concrete class implementation (based on GSIArray) may be a problematic approach: perhaps the representation should fundamentally be a hash-map to rapid testing of membership, rather than an array for rapid enumeration and access by index (or both data structures could be used to hold the same objects).

If we assume that it's acceptable for access by index to be really slow for very large collections, it would be possible to implement this based on an extended version of GSIMap (or some other hash table implementation), since this contains a linked list of nodes (and of course the linked list would be used to provide ordering and access by index). The modification required would be having an alternative version of the node addition code to maintain the linked list ordering, as well as a version of the code to resize the GSIMap (so it maintains the list ordering).

Alternatively, (simplest code approach giving high performance for both forms of access, but higher memory footprint), I'd use both a GSIMap and a GSIArray and store objects in both. In that case it would make sense to configure one data structure to manage retain/release and the other data structure to refrain from doing retain/release.

Write tests for the "passingTest" methods in NSOrderedSet

Source/NSOrderedSet.m
options:(NSEnumerationOptions)opts
passingTest:(GSPredicateBlock)predicate
{
return [[self objectsAtIndexes: indexSet]
@fredkiefer
fredkiefer 18 days ago Member
I would expect that this yields the wrong result, as the index will be from the wrong set.

I will write a test on macOS and compare output when the test is moved over to GNUstep

Add plutil(1)

Since its introduction in Mac OS X 10.2, many users of the said system have started to seen plutil(1) as the only plist command-line editor. plutil(1) is a program that does most of pldes(1) and friend does, but all put in one tool. Around macOS 10.15, plutil(1) seems to have received a lot of editing capabilities that are not found in online manpages.

I am currently working on a version of plutil for GNUstep, sans the programming language and JSON literal features for now. This issue is really just for a future pull request reference.

plutil(1) manpage in macOS 10.14: https://www.unix.com/man-page/mojave/1/plutil
plutil(1) manpage in macOS 10.15: plutil.1.gz

A related utility found on macOS but not yet in GS is PlistBuddy. Both utilities have a MIT/Expat licensed C++ implementation by Facebook at https://github.com/facebook/xcbuild/tree/master/Libraries/plist/Tools. I am mainly writing plutil(1) from scratch for the new 10.15 features.
