From d1cc47b337adadf3f34ae3bcd585ef3e27258073 Mon Sep 17 00:00:00 2001 From: Sam Lantinga Date: Sun, 17 Aug 2014 15:07:00 -0700 Subject: [PATCH] Fixed 2680 - OSX: Replace NSAutoreleasePool with @autoreleasepool Tim McDaniel This patch replaces all use of NSAutoreleasePool with the Apple recommended @autoreleasepool. @autoreleasepool is supposedly more efficient, and since it is scope based it can't be accidentally not released. --- src/file/cocoa/SDL_rwopsbundlesupport.m | 8 ++---- src/filesystem/cocoa/SDL_sysfilesystem.m | 10 +++----- src/video/cocoa/SDL_cocoaclipboard.m | 24 +++++------------- src/video/cocoa/SDL_cocoaevents.m | 13 +++------- src/video/cocoa/SDL_cocoakeyboard.m | 11 +++----- src/video/cocoa/SDL_cocoamessagebox.m | 7 ++---- src/video/cocoa/SDL_cocoamodes.m | 7 ++---- src/video/cocoa/SDL_cocoamouse.m | 32 ++++++++---------------- 8 files changed, 34 insertions(+), 78 deletions(-) diff --git a/src/file/cocoa/SDL_rwopsbundlesupport.m b/src/file/cocoa/SDL_rwopsbundlesupport.m index f6a65a99a41ed..1ae399c2d7e05 100644 --- a/src/file/cocoa/SDL_rwopsbundlesupport.m +++ b/src/file/cocoa/SDL_rwopsbundlesupport.m @@ -33,6 +33,7 @@ Also, note the bundle layouts are different for iPhone and Mac. */ FILE* SDL_OpenFPFromBundleOrFallback(const char *file, const char *mode) +{ @autoreleasepool { FILE* fp = NULL; @@ -41,9 +42,6 @@ return fopen(file, mode); } - NSAutoreleasePool* autorelease_pool = [[NSAutoreleasePool alloc] init]; - - NSFileManager* file_manager = [NSFileManager defaultManager]; NSString* resource_path = [[NSBundle mainBundle] resourcePath]; @@ -57,10 +55,8 @@ fp = fopen(file, mode); } - [autorelease_pool drain]; - return fp; -} +}} #endif /* __MACOSX__ */ diff --git a/src/filesystem/cocoa/SDL_sysfilesystem.m b/src/filesystem/cocoa/SDL_sysfilesystem.m index adcebd68b7612..dab51c501389d 100644 --- a/src/filesystem/cocoa/SDL_sysfilesystem.m +++ b/src/filesystem/cocoa/SDL_sysfilesystem.m @@ -35,8 +35,8 @@ char * SDL_GetBasePath(void) +{ @autoreleasepool { - NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSBundle *bundle = [NSBundle mainBundle]; const char* baseType = [[[bundle infoDictionary] objectForKey:@"SDL_FILESYSTEM_BASE_DIR_TYPE"] UTF8String]; const char *base = NULL; @@ -62,14 +62,13 @@ } } - [pool release]; return retval; -} +}} char * SDL_GetPrefPath(const char *org, const char *app) +{ @autoreleasepool { - NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; NSArray *array = NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES); char *retval = NULL; @@ -96,9 +95,8 @@ } } - [pool release]; return retval; -} +}} #endif /* SDL_FILESYSTEM_COCOA */ diff --git a/src/video/cocoa/SDL_cocoaclipboard.m b/src/video/cocoa/SDL_cocoaclipboard.m index c2f3be73ccb87..bf3b90955a5b4 100644 --- a/src/video/cocoa/SDL_cocoaclipboard.m +++ b/src/video/cocoa/SDL_cocoaclipboard.m @@ -37,34 +37,28 @@ int Cocoa_SetClipboardText(_THIS, const char *text) +{ @autoreleasepool { SDL_VideoData *data = (SDL_VideoData *) _this->driverdata; - NSAutoreleasePool *pool; NSPasteboard *pasteboard; NSString *format = GetTextFormat(_this); - pool = [[NSAutoreleasePool alloc] init]; - pasteboard = [NSPasteboard generalPasteboard]; data->clipboard_count = [pasteboard declareTypes:[NSArray arrayWithObject:format] owner:nil]; [pasteboard setString:[NSString stringWithUTF8String:text] forType:format]; - [pool release]; - return 0; -} +}} char * Cocoa_GetClipboardText(_THIS) +{ @autoreleasepool { - NSAutoreleasePool *pool; NSPasteboard *pasteboard; NSString *format = GetTextFormat(_this); NSString *available; char *text; - pool = [[NSAutoreleasePool alloc] init]; - pasteboard = [NSPasteboard generalPasteboard]; available = [pasteboard availableTypeFromArray: [NSArray arrayWithObject:format]]; if ([available isEqualToString:format]) { @@ -82,10 +76,8 @@ text = SDL_strdup(""); } - [pool release]; - return text; -} +}} SDL_bool Cocoa_HasClipboardText(_THIS) @@ -101,13 +93,11 @@ void Cocoa_CheckClipboardUpdate(struct SDL_VideoData * data) +{ @autoreleasepool { - NSAutoreleasePool *pool; NSPasteboard *pasteboard; NSInteger count; - pool = [[NSAutoreleasePool alloc] init]; - pasteboard = [NSPasteboard generalPasteboard]; count = [pasteboard changeCount]; if (count != data->clipboard_count) { @@ -116,9 +106,7 @@ } data->clipboard_count = count; } - - [pool release]; -} +}} #endif /* SDL_VIDEO_DRIVER_COCOA */ diff --git a/src/video/cocoa/SDL_cocoaevents.m b/src/video/cocoa/SDL_cocoaevents.m index 3474d159ad926..13aeb4502f6b7 100644 --- a/src/video/cocoa/SDL_cocoaevents.m +++ b/src/video/cocoa/SDL_cocoaevents.m @@ -248,17 +248,16 @@ - (BOOL)application:(NSApplication *)theApplication openFile:(NSString *)filenam void Cocoa_RegisterApp(void) +{ @autoreleasepool { /* This can get called more than once!
