CoreFoundation is a cross-platform C-based API that provides reference-counted data structures, IPC facilities, run loops, etc. A subset of it is open-sourced as "CF-Lite".
This framework also provides some crucial Objective-C classes such as NSObject, NSString, NSArray, etc.
Environment variables
Application built with CoreFoundation will recognize the following environment variables
| Name | Purpose |
|---|---|
| NSZombieEnabled[1] NSDeallocateZombies CFZombieLevel[2] |
Use "zombies" for easier detection on misusing deallocated objects. |
| __CF_DEBUG_EXPANDED_SET CFCharacterSetCheckForExpandedSet |
Enable check for expanded character sets. When an expanded set is detected, a message "An expanded CFMutableCharacter has been detected. Recommend to compact with CFCharacterSetCreateCopy" will be printed. |
| CFBundleUseDYLD | Use low-level dyld(3) functions instead of dlopen(3)/etc. to check if a bundle is loaded or not. |
| CFProcessPath | Manually set the process path. |
| OAKeepAllocationStatistics[3] | ? |
| CFBundleDisableStringsSharing | Do not share .strings files. (?) |
| CFPropertyListAllowImmutableCollections | Force collections (array, dictionary) parsed from property lists to be immutable. |
| USER HOME PATH DYLD_IMAGE_SUFFIX |
Various CF functions depend on these info. |
| CFFIXED_USER_HOME | Manually set the home directory. |
| CFUUIDVersionNumber[4] | UUID version to use. Only supports 1 or 4. |
| CFLOG_FORCE_STDERR | Stream error from CFLog to stderr too. |
| TZFILE TZ |
Timezone info. |
| CFNETWORK_LIBRARY_PATH | Manually set the path of the CFNetwork binary. |
