mmkv's Issues

synchronize is deprecated and will be marked with the NS_DEPRECATED macro in a future release.(from Apple)

This is a great frameworks to solve the key-value read/write problems, and has great performance comparing to NSUserDefaults and SQLite。It use the mmap, protobuf and some elegant strategies。

My question is your idea is base on the NSUserDefaults's poor performance is due to synchronize call, but from apple, synchronize will be deprecated and should be remove the synchronize call. (synchronize is deprecated and will be marked with the NS_DEPRECATED macro in a future release.)

mmkv是否是线程安全的？

想问下，mmkv是否是线程安全的？

Default value was not returned when decode type and encode type mismatch

If we write some data of type A and read it as type B with the same key, unexpected value will be returned. For example:

MMKV kv = MMKV.mmkvWithID(mmapID, MMKV.SINGLE_PROCESS_MODE, cryptKey);
kv.encode("bool", true);
int val = kv.decodeInt("bool", 100);
System.out.println("decode int with key bool: " + val);

The terminal will print decode int with key bool: 1. That is kind of misleading since we never store any int value with key "bool", meanwhile there was no error or exception thrown when we are doing this implicit casting.

Is this an intentional design?

标题里面单词是不是拼错了 ?

jnilibs take up a lot of space, and Can I remove some of them?

【建议】压缩int的时候，如果是负数，现在实现中的压缩结果有点浪费空间

void CodedOutputData::writeInt32(int32_t value) { if (value >= 0) { this->writeRawVarint32(value); } else { this->writeRawVarint64(value); } }

不明白为什么要采用现在这种压缩方法。
zigzag 压缩负数的效率应该比 writeRawVarint64 的实现要好一些

支持数据监听吗？

日常开发经常会遇到对存储数据变化监听，mmkv支持数据监听吗？

进程问题

看了项目描述，初步看了下代码，有以下2点疑问点需要帮助：

protobuf文件支持自定义么
跨进程可见么

Expected NDK STL shared object file at /Users/didi/Library/Android/sdk/ndk-bundle/sources/cxx-stl/llvm-libc++/libs/armeabi/libc++_shared.so

MMKV.mmkvWithID crash

MMKV.mmkvWithID("test/hello2").encode("hello", "world")

id中使用/会导致崩溃

onDestroy方法中必须调用MMKV.onExit()方法嘛？

onDestroy方法调用MMKV.onExit是为了清除缓存嘛？还有其它作用嘛？如果不调用有什么问题？

初始化卡顿然后闪退

        var kv = MMKV.defaultMMKV()

调用这行代码，卡顿，然后就闪退了，除了这个
Fatal signal 11 (SIGSEGV) at 0x00000004 (code=1), thread 17055 (com.zxy.app)
没有看到其他的任何日志。
是我使用方式错了吗。

It looks like your repo is trending. The github_trending_videos Instgram account automatically shows the demo gifs of trending repos in Github.

Your README doesn't seem to have any demo gifs. Add one and the next time the parser runs it will pick it up and post it on its Instagram feed. If you don't want to just close this issue we won't bother you again.

- (BOOL)setObject:(id)object forKey:(NSString *)key NS_SWIFT_NAME(set(_:forKey:));

支持的类型只有 NSString/NSData/NSDate 这三种，为什么不是分成三个不同的方法而是采用通用 id 来处理呢？

- (BOOL)setString:(NSString *)string forKey:(NSString *)key NS_SWIFT_NAME(set(_:forKey:));
- (BOOL)setDate:(NSDate *)date forKey:(NSString *)key NS_SWIFT_NAME(set(_:forKey:));

OOM caused by mmkv file size too large.

What's the possible reason for actualSize much less than file size, multi-process read & write in single process mode?

Support for macOS?

[!] The platform of the target TestOfMacOS (macOS 10.13) is not compatible with MMKV (1.0.10), which does not support osx.

如果macOS App是单进程模式，MMKV现在能支持吗？

Why do you detect self == MMKV.class in initialize ?

+ (void)initialize {
	if (self == MMKV.class) {
		static dispatch_once_t onceToken;
		dispatch_once(&onceToken, ^{
			g_instanceDic = [NSMutableDictionary dictionary];
			g_instanceLock = [[NSRecursiveLock alloc] init];

			MMKVInfo(@"pagesize:%d", DEFAULT_MMAP_SIZE);
		});
	}
}

why not support NSDictionary as NSUserDefault

The language of MMKV

Objective-C

The version of MMKV

v1.0.10

The platform of MMKV

iOS

The installation of MMKV

Cocoapods

What's the issue?

For me, I often use a NSUserDefault to do some simple data persistence. And the NSDictionary is a very important one. Why is there no support for it?

About layout of the mmaped file

After calling mmkv.putInt("int", 100) several times, I got a file named after mmkv id under the app's data folder. By inspecting the file content with xxd, I am a little bit confused about the layout of the file.

The first four bytes are value of m_actualSize ，and we have 6700 0000 0x67 = 103 bytes.
Then we have 0603 696e 7401 64
- 06 is the size of the map
- 03 696e 74 represents the length(03 bytes) and content of the key (696e 74, "int")
- 01 64 represents the length(01 bytes) and the content of the value (0x64 = 100)

Why do we need to write size of the map into the mmaped file anyway? It seems that the size is of no use when decoding.
