Cache fails to store large files

[vilinskiy-playdayteam]

Whenever we try to save large files (>100MB, actual size depends on device capabilities) to cache, nothing happens except console log message like

*** mach_vm_map(size=997462016) failed (error code=3)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug

The problem is in SPTPersistentCache method

- (NSError *)storeDataSync:(NSData *)data
                    forKey:(NSString *)key
                       ttl:(NSUInteger)ttl
                    locked:(BOOL)isLocked
              withCallback:(SPTPersistentCacheResponseCallback)callback
                   onQueue:(dispatch_queue_t)queue

The following code does not work for large rawDataLength
NSMutableData *rawData = [NSMutableData dataWithCapacity:rawDataLength];

One way to handle large amounts of data is to fill temporary file with relatively small blocks of data first and then writing it atomically to target filePath

Thanks I'll look into it
