viabtc_exchange_server's Introduction

ViaBTC Exchange Server

ViaBTC Exchange Server is a trading backend with high-speed performance, designed for cryptocurrency exchanges. It can support up to 10000 trades every second and real-time user/market data notification through websocket.

Architecture

For this project, it is marked as Server in this picture.

Code structure

Required systems

MySQL: For saving operation log, user balance history, order history and trade history.
Redis: A redis sentinel group is for saving market data.
Kafka: A message system.

Base library

network: An event base and high performance network programming library, easily supporting 1000K TCP connections. Include TCP/UDP/UNIX SOCKET server and client implementation, a simple timer, state machine, thread pool.
utils: Some basic library, including log, config parse, some data structure and http/websocket/rpc server implementation.

Modules

matchengine: This is the most important part for it records user balance and executes user order. It is in memory database, saves operation log in MySQL and redoes the operation log when start. It also writes user history into MySQL, push balance, orders and deals message to kafka.
marketprice: Reads message(s) from kafka, and generates k line data.
readhistory: Reads history data from MySQL.
accesshttp: Supports a simple HTTP interface and hides complexity for upper layer.
accwssws: A websocket server that supports query and pushes for user and market data. By the way, you need nginx in front to support wss.
alertcenter: A simple server that writes FATAL level log to redis list so we can send alert emails.

Compile and Install

Operating system

Ubuntu 14.04 or Ubuntu 16.04. Not yet tested on other systems.

Requirements

See requirements. Install the mentioned system or library.

You MUST use the depends/hiredis to install the hiredis library. Or it may not be compatible.

Compilation

Compile network and utils first. The rest all are independent.

Deployment

One single instance is given for matchengine, marketprice and alertcenter, while readhistory, accesshttp and accwssws can have multiple instances to work with loadbalancing.

Please do not install every instance on the same machine.

Every process runs in deamon and starts with a watchdog process. It will automatically restart within 1s when crashed.

The best practice of deploying the instance is in the following directory structure:

matchengine
|---bin
|   |---matchengine.exe
|---log
|   |---matchengine.log
|---conf
|   |---config.json
|---shell
|   |---restart.sh
|   |---check_alive.sh

API

HTTP Protocol and Websocket Protocol documents are available in Chinese. Should time permit, we will have it translated into English in the future.

There is also a third-party OpenRPC Document available.

Third-party Clients

Websocket authorization

The websocket protocol has an authorization method (server.auth) which is used to authorize the websocket connection to subscribe to user specific events (trade and balance events).

To accommodate this method your exchange frontend will need to supply an internal endpoint which takes an authorization token from the HTTP header named Authorization and validates that token and returns the user_id.

The internal authorization endpoint is defined by the auth_url setting in the config file (accessws/config.json).

Example response: {"code": 0, "message": null, "data": {"user_id": 1}}

Example of connecting to accessws

Hey guys, does any has the example of connecting to accessws? Having trouble in finding the origin of problem. Wireshark shows that connecting is stalling on waiting of first handshake message from accessws. @haipome

关于订单权限问题.

@haipome 你好.
正在学习您的项目,现在刚刚部署完成,
产生了新的疑问.
项目里貌似没有用户管理这一块的服务.
通过accesshttp能直接对户资产进行更改.
是否是说accesshttp不能直接对外进行服务,
所有接口只对内网的用户类webserver连接开放?
想请教下设计思路,谢谢.

Different results from market.status_today and market.status (period=86400), expected?

Hello @haipome! Could you please elaborate should the responses from market.status_today and market.status with period=86400 return different results?

./marketprice.exe: init message fail: -356: Connection refused

I got an error when I run marketprice.exe
./marketprice.exe: init message fail: -356: Connection refused

how to fix it?

database schema?

Is it possible to get some information about how the database is designed?

For instance it looks like each user in the system gets a set of their own tables (order_history_%u, order_detail_%u, deal_history_%u, user_deal_history_%u, balance_history_%u). Is there a reason for that?

Hi Haipo, have a question about authentification, authorization methods!

Can you provide some more info about the authorization, authentification user methods? Where info about user comes from. Where is it stored.

no "total" field for order.completed RPC

The order.pending RPC returns a "total" field (indicating the total number of records that one could request using the offset and limit fields) but order.completed does not have this field (same with balance.history)

Looking at the code I guess we could do a "SELECT count()" type query as well (in rh_reader.c get_user_order_finished()).. but I guess it could add a bit more load to the server

What's the source code licence terms?

Hi,

there's no license terms in your whole source code.
example, what I'm saying is MIT or Apache or GPL or LGPL or ...
Or, Your company internal license term.

It may be freely studying use now.
Source code has opened but, Licenses are still live.
So you can describe exact source code license terms in your souce code.

Good study materials.
thanks.

accessws, depth.updates, interval len("0.00000001") >= INTERVAL_MAX_LEN

Hey @haipome, I believe that in order to subscribe on depth.update in accessws with interval 0.00000001 (which is specified as available in config.json) we have to make INTERVAL_MAX_LEN a bit bigger, or am I missing something?

Is serialization questions. when using thread pool.

example in ut_dict.c ,
there's widely referenced dictionary hash table generation functions.
in mp_server.c , trade , me_main.c , they uses threadpool ,
but, I can't find dict function / balance categorie (mpdecimal use) , and several global variable doesn't protected on MT-safe condition.

where can I find serialzation code? it is exists in just thread pool add/remove functions only.

Is there any way to watch to input and to output data?

I install all of thing and operate all servers into one physical server.
After this, I don't know next steps about watching inserting data.
Is there anyone who know something like above?

include header file modification for mixing with C++ sourcecode.

in most case,
C programmers write their source code with following ways::

----------- viabtc_exchange_server/matchengine/me_cli.h -------------------

# ifndef _ME_CLI_H_
# define _ME_CLI_H_

int init_cli(void);

# endif

To modified for mixing C/C++ source code.

---------- sample of modify the code -----------------------------------------

# ifndef _ME_CLI_H_
# define _ME_CLI_H_

#ifdef __cplusplus
extern "C" {
#endif

int init_cli(void);

#ifdef __cplusplus
}
#endif

# endif

** sample link ::

viabtc_exchange_server/matchengine/me_cli.h

Line 8 in 3da9c87

限价单逻辑是否反了？

在execute_limit_ask_order里，判断

if (mpd_cmp(taker->price, maker->price, &mpd_ctx) > 0) {
break;
}

这样的话，挂买单，撮合的都是卖价大于等于买价的，买贵了。
在execute_limit_bid_order里则是

if (mpd_cmp(taker->price, maker->price, &mpd_ctx) < 0) {
break;
}
这个，挂卖单，撮合的也是买价小于等于卖价的，卖便宜了。

Some questions about the project

Hello, haipo!

I have some questions about your project https://github.com/viabtc/viabtc_exchange_server

I will be happy if you answer these questions:

Firstly, I didn't see the ViaBTC when it was working and I don't know how much people use it. My question is: why do you use MySQL?
Maybe, a preferred database will be MongoDB or another NoSQL database? I know about the persistence, so we can enable it in MongoDB.
Which was the load on the system when the ViaBTC was working?
Why did you use the C? Is it your the main programming language?

Thanks!

order.put_market, amount, inconsistency

Hey @haipome ! We have noticed inconsistency in what we have to specify in the field amount for order.put_limit and order_put_market, and I am wondering is that was done intentionally or not.

In the command order.put_limit amount corresponds to the number of stocks user wants to buy/sell.

In the command order.put_market when we use bid side amount corresponds to number of money user wants to spend on buying the stock, and when we use ask side amount corresponds to the stock user want to sell. Wouldn't it be better to make it consistent or probably I am missing something? Thanks!

Command	Side	Meaning of `amount`
order.put_limit	ask	stock
order.put_limit	bid	stock
order.put_market	ask	stock
order.put_market	bid	money

what is a "slice"?

I am trying to understand some of the terms in db.
There are a lot of tables "slice_balance_%timestamp%", "slice_order_%timestamp%" created over time. Are they meant to be deleted after a while?

Recommend log , balance server from MySQL to NoSQL DB.

I think MySQL server using the store logs, user balances, important imformation.
It will used NoSQL based backend (eg. mongodb , ... ) for scalabilities and securities .
using the sharding and replication technology.
MySQL is Popular using R-DBMS and Also secure , but it's central and websites store passwd.
It's hard to expanding and backuping the data , in realtime.

Hi Haipo, is it possible to get installation service from you ?

Hi Haipo,

Glad to see you still maintain this viabtc_exchange_server script even your exchange business was closed due to government regulation

I am working to setup my exchange business and looking for industrial standard and well tested software for the exchange server and may use via BTC

Could you please advise if possible to me to get support from your side ?, we can do good exchange business

Lookign forward for your reply

Thank you

Regards,
Sardan

Completion of error handling

Would you like to add more error handling for return values from functions like the following?

malloc ⇒ update_dict_key_dup
pthread_mutex_init ⇒ dlog_init

please give more document on this code

how can I start it up?

frontend and web api

Hi,

How can we do frontend and web API?

Newbie - compilation

I set up a Ubuntu 16.04 vm to learn this project myself. I am having trouble compiling the network module with included makefile.

Can someone post a more detailed guide on how to install / compile / use dependency libs then the server modules?
I was able to fetch some libs via apt-get, but many other libs (i.e. libev) seem to require recompilation from source with automake, which I don't have a clue.
Also, once I am able to compile the dependency lib, how do I make use of it to compile higher level modules such as "network"?

Much appreciated.

Update balance

Hello!
How to add coin daemons support to your exchange server?
Thx, max
;)

请问me_persist.c中的dump_to_db是如何保证operlog_id_start与dump的order和balance的一致性？

int dump_to_db(time_t timestamp)函数中先执行了dump_order_to_db、dump_balance_to_db然后使用update_slice_history记录当前的operlog_id。是否可能导致记录的operlog_id大于dump_order_to_db、dump_balance_to_db时的实际id，在恢复数据时导致漏执行operlog？

time difference api usage.

viabtc_exchange_server/utils/ut_log.c

Line 90 in 3da9c87

static inline uint64_t timeval_diff(struct timeval *old, struct timeval *new)

in case of unix based time api has lack of limitation, wrap-around cases happen.
at normal time , it is not a problem.
but, we don't know the future.
So, there's recommendation way and api proposed by Posix and GNU.

Here's link.

How do I insert asset data?

I got a great help from djpnewton.
However, I am in trouble to insert market data into exchange server.

I have 2 questions
one is that how to input asset data.
two is that if accessws server is the one to insert data, how do I use it? how do I install it?

Dependency configuration

Hi Haipo,

Could you please share the configuration and setup instructions for Zookeeper, Kafka, and Redis server+sentinel?

Thanks.

marketprice.exe error message

# ./marketprice.exe: init message fail: -309: Connection refused

Anyone know this messages reason?
I am not familiar with Redis db and C language. So I was in hardship.

same result , but it's not expandable code.

viabtc_exchange_server/matchengine/me_market.c

Line 42 in 3da9c87

memcpy(obj, key, sizeof(struct dict_user_key));

struct dict_order_key {
    uint64_t    order_id;
};
...

static void *dict_order_key_dup(const void *key)
{
    struct dict_order_key *obj = malloc(sizeof(struct dict_order_key));
    memcpy(obj, key, sizeof(struct dict_order_key));
    return obj;
}

no consistency of codes, some where checking null , some where not.
it's recommended the member variable copy. obj->order_id = key->order_id
in future you expand struct , then this code will be more safe and expandable easily.

reserved identifier violation

I would like to point out that identifiers like “_ME_MARKET_H_” and “_RH_SERVER_H_” do not fit to the expected naming convention of the C language standard.
Would you like to adjust your selection for unique names?

while I compiled the C files , the following errors show: /usr/lib/gcc/x86_64-linux-gnu/5/../../../x86_64-linux-gnu/libmysqlclient.a(my_default.cc.o):(.data.DW.ref.__gxx_personality_v0[DW.ref.__gxx_personality_v0]+0x0): undefined reference to __gxx_personality_v0'

Unique id in balance.update

There is rather specific problem with lack of unique id's in balance.update - it leads React application to rerender the whole array of entries because keys are not unique.
I'm convinced that besides React it might lead to problems in other cases, for example caching or logging.
Also it's a bit inconsistent with deals and orders :)

I am in trouble to install viabtc_server

Error Message
/root/exsv/matchengine/me_message.c:45: undefined reference to `rd_kafka_last_error'

Even if I do my best, I couldn't find any solutions up to now.
The list of what I do

I changed all position of options for compiling
ex) -Wl,-Bstatic -lev -ljansson -lmpdec -lmysqlclient -lz -lrt -lstdc++ -lrdkafka -lssl -lcrypto -lhiredis -Wl,-Bdynamic -lm -lpthread -ldl
I changed rdkafka.h on the last version 0.94.

There are any other ways?

balance update return repeat update

你好：
第一次运行结果
./cli.exe 192.168.0.100 7316 102 '[1, "LTC", "deposit", 10001, "100000",{}]'
{
"id": 0,
"error": null,
"result": {
"status": "success"
}
}

第二次得到
./cli.exe 192.168.0.100 7316 102 '[1, "LTC", "deposit", 10001, "100000",{}]'
{
"id": 0,
"error": {
"message": "repeat update",
"code": 10
},
"result": null
}

查看代码是下面返回了-1
int update_user_balance(bool real, uint32_t user_id, const char *asset, const char *business, uint64_t business_id, mpd_t *change, json_t *detail)
{
struct update_key key;
key.user_id = user_id;
strncpy(key.asset, asset, sizeof(key.asset));
strncpy(key.business, business, sizeof(key.business));
key.business_id = business_id;

dict_entry *entry = dict_find(dict_update, &key);
if (entry) {
    return -1;
}

..........

请问这样设计的逻辑是什么？

///////////
另外，是否有情况发生这样的事，有人攻破进入martchmachine部署的服务器,随意修改balance,然后随意下单，引起市场价格剧烈波动。

感谢。

length of order skip list hasn't been decreased

Probably I am wrong, but it seems like sometimes the length of order skip list hasn't decreased during order cancel.

Finished order, price zero.

Hey @haipome @djpnewton, sometimes we ended up with zero price in mysql for one of the finished orders, have you encountered the same situation or probably it is expected behaviour?

But in the deals the price is not equals to zero 🤔

How to add second, third main trade currency

Now in exchange server there is only one main trade currency - BCH, all assets are trading against BCH. How can I add BTC, ETH, USD, EUR or more currencies for trading pairs.
For example, now I can trade only ETH/BCH, but I want to trade ETH/USD, ETH/BTC or may be even ETH/NEO. Could anybody help ?

If you hit the issues in build and start the service, see my exp!

I added how to build and run services at the end of https://github.com/yingl/viabtc_exchange_server/blob/master/README.md. I also modified the code to make sure no fucking link issues, except the accessws, all other services get started OK.

关于安装viabtc_exchange_server的问题.

首先谢谢作者的开源.
在部署viabtc_exchange_server过程忠,目前碰到两个问题想请教一下作者.

1 marketprice中redis_sentinel_connect_master会被定时调用获取redis主节点,
代码中我并没有找到对于redis_sentinel_connect_master的定时器发起点,
所以只能猜测这个定时器只是单纯用来时刻获取主节点的.
但从netstat看来,这个连接并没有长链,都是发起一次关闭一次的.
所以想请问,这个行为是正确的吗?

2.matchengine启动时报错
[2017-11-27 10:30:37.701069] [11483] [error]me_persist.c:96(load_operlog_from_db): table operlog_20171127 not exist
这是正常的吗?
如果不正常,是否是要做个定时任务每天根据operlog_example来创建operlog_ymd表?

kafka deals数据堆积

每秒3000笔的下单时，deals数据会堆积，marketprice消费速度开始正常后面就非常慢，kafka服务器没打印错误日志。
用python写的代码消费deals数据，没有出现问题
不知道该如何定位和解决？非常感谢
