Best HTTP Released

@BestHTTP Hi, I'm using best http 2 for my game. There is strange issue in receiving broadcast.
There are 2 players on the table when 2nd player joins the table for the first time he doesn't get any broadcast he has to rejoin the table but 1st player gets all broadcast he doesn't have to rejoin.

 

@hermit_021

It would be very valuable to know what protocol are you using (socket.io, signalr, etc.), and how do you send your broadcasts.

 

@BestHTTP, I'm using socket.io. and let me describe it bit more. as I said second player is not getting broadcast but the case is, there are two classes for both i have subscribe the broadcast in onenable one of them is called but not the other one. Both are active in scene in debug i get logs for onenable method from both classes from both players but both methods of that broadcast is called for 1st joined player only 2nd player have to rejoin in order to get call both methods.

 

@hermit_021 Could you show your code?

 

Both game objects are active and both scripts are also enabled.

 

@hermit_021 I couldn't replicate your issue, and in this case verbose logging wouldn't help as On and Off cals aren't logged. So could you send a minimal repro project?

Also, please note that calling Off removes all callbacks for that event name!

 

@BestHTTP
hi, here's my context.
i'm using socketio3 to send my webcamtexture to python server.
i have a texture which has a resolution about 640x480, and i encoded it to JPG format, and then send it through socketio.
i profiled with my tablet Lenovo P11, and i'd like to know how to optimize this.
it seems that zlib take a lot of time.
is there way not to compress my data before sending?
any other solution will save me
thanks in advance.

 

@gawoon The new version in the works can help solving it by
1. giving a way to disable websocket extensions
2. moving extension and websocket frame creation to the sender thread

In your case both will be helpful as JPG already a compressed format, further compression can be only a waste of CPU time, so disabling the per-message deflate extension is a good step to consume less cpu.

If you drop me a mail at besthttp@gmail.com i can send a package with the new version.

 

awesome!
here's my email, choigawoon@gmail.com
also wonder if when do you think new version is released on the package manager?
oops, i sent the mail to you also.

 

hi again.
your solution work perfectly. thanks a lot!
before about 100ms -> now about 1-2ms

 

Hello，How to Authentication by password and username？

 

@1002711414 Depends on what kind of authentication the server expects, but HTTP Basic and Digest authentication can be done using the Credentials property: https://benedicht.github.io/BestHTT...best_http2/protocols/http/Authentication.html

 

@BestHTTP
Hello,
I have been experiencing a problem with the BestHTTP package for some time, on some Android devices the HTTPRequest functions and requests with SignalR (HubConnection when sending) crash the application. I did several tests but the application crashes without any particular message on the Play Store (except a SIGBUS and SIGSEGV message and more recently a "[libil2cpp.so] BestHTTP47.cpp - FastChaCha7539Engine_DoFinal_mB94251F11244EE9C50414238F8C1CF04D467191A" message related to a SIGBUS error). I changed the HTTPRequest functions to UnityWebRequest and it works but I haven't found an alternative for SignalR.

(I would like to point out that this crash only happens to 1% of our users and they all use a Samsung Galaxy A13)

Thanks in advance for your help!

Edit : I'm using Unity 2021.3.16f1

 

@JosephEgens What version of the plugin and Unity are you using?

 

I'm using Unity 2021.3.16f1 and BestHTTP/2 V 2.8.2

 

@JosephEgens I saw nothing suspicious in the FastChaCha7539Engine's DoFinal method, however under Unity 2021.2 or newer it uses BouncyCastle's new Span based APIs.
Drop me a mail at besthttp@gmail.com (or you can join to the plugin's discord server and send a private message) and will send a new package that will disable the Span based APIs so we can see whether it makes any change.

 

Hello,
Thank you for your reactivity, with the plugin that you sent me, the requests do not cause any more crashes and work properly.
Thank you again for your help !

 

I made it as an echo server with WebsocketSharp, and made it as a BestHTTP.WebSocket client and tested it, but the following error occurred.
This is for a simple test to send and receive 38,553 bytes. please tell me how to solve it
Request Finished with Error! Exception: TCP Stream closed unexpectedly by the remote server

@darydol What version of the plugin are you using? You can check it by printing out HTTPManager.UserAgent (or just check it in the source).

 

Hi @BestHTTP !
We have a question regarding your TLS plugin.
Can't we get any problem with security if anybody on Android can access the folder where you store the metadata? Any sensitive data there?

 

Indeed, HTTPManager.GetRootCacheFolder returns with UnityEngine.Application.persistentDataPath that uses
getExternalFilesDir: "any application holding Manifest.permission.WRITE_EXTERNAL_STORAGE can write to these files."

While i think risks are low, you can use HTTPManager.RootCacheFolderProvider to set a custom value.
I'm going to check how i could use getDir instead under Android.

 

Hi @BestHTTP.
When I try to make an HTTP/2 GET request on the device with the Turkish language as a default, it is declined by the server. The client error is

Code (CSharp):

1. Exception: System.Exception: RST_STREAM frame received! Error code: PROTOCOL_ERROR(1)

The server error is invalid_headers.

The headers from Charles are provided in the image below, and two of the headers have strange symbols instead of the letter "I". I do not modify these 2 headers anywhere in my app, but I see that they are used in the BestHttp plugin. Do you know how I can fix this?

 

@unity_ci
Thanks for the details! The plugin used ToLower instead of ToLowerInvariant in a few places. Sent a link to an updated package in private.

 

Hey BestHTTP team, we're devloping an AR app that initially loads textures over HTTP to put them on objects around you. We implemented a job system that schedules the texture downloads based on how close those objects are to the user, so not all of them are being loaded at once.

We were still seeing frame drops when using Unity's texture download, so we switched to BestHTTP's download implemention hoping that we can get rid of these frame drops as it is multi-threaded.

However, we noticed that the frame drops still occur. When profiling, we saw that in each performance spike around 95% of the time is spent on the HTTPUpdateDelegator. Below that node, we see a lot of GC.Alloc calls for around 62mb of data. Is there any chance to speed up things here?

EDIT: The problem was caused by another library which I called in the callback. So all good, sorry for bothering.

 

@waldgeist

HTTPUpdateDelegator is the link between the plugin and Unity. Its Update function is called by Unity, and that's where all the callbacks are called. Because of this, everyhing you do in the HTTPRequest's callback will be show up under HTTPUpdateDelegator in the profiler.
Also, all memory for the downloaded content is allocated outside of the Unity main thread, if you access the content through HTTPResponse's Data property, the plugin doesn't allocate any additonal memory. If you use DataAsTexture2D, then the plugin only creates the Texture2D:

Code (CSharp):

1. public Texture2D DataAsTexture2D
2. {
3.     get
4.     {
5.         if (Data == null)
6.             return null;
7.  
8.         if (texture != null)
9.             return texture;
10.  
11.         texture = new Texture2D(0, 0, TextureFormat.RGBA32, false);
12.         texture.LoadImage(Data, true);
13.  
14.         return texture;
15.     }
16. }

The plugin also has an internal BufferPool to reuse allocated byte[]s, and there's a very high chance that after the first download the plugin only allocates memory for the final downloaded content (except the headers of course).

 

Hello, sorry to bother but it seems I'm having some issue with BestHTTP when my Managed Stripping Level is set to minimal. When it's on disabled everything is working fine but when it's on minimum I'm getting this error :

Unfortunately since we are releasing our project on IL2CPP plateform we can't disable Managed Stripping Level.
I've tried putting BestHTTP and other things in a link.xml file to prevent them for being stripped but it didn't work.

Code (csharp):

1. <linker>
2.   <assembly fullname="System">
3.     <type fullname="System" preserve="all" />
4.   </assembly>
5.   <assembly fullname="UnityEngine">
6.     <type fullname="UnityEngine" preserve="all" />
7.   </assembly>
8.   <assembly fullname="BestHTTP">
9.     <type fullname="BestHTTP" preserve="all" />
10.   </assembly>
11. </linker>

It might come from a different script being stripped but at this point I'm stuck and only see this.

 

@Ludogram

The exception happened in MMatchmaking.Match (DirectoryGame game, System.Boolean host) [0x0002d] in C:\\[path]\\MMatchmaking.Command.cs:22 \r\n at MMatchmaking.<_NewOnlineGame>b__55_0 (BestHTTP.HTTPRequest req, BestHTTP.HTTPResponse res) [0x00034] in C:\\[path]\\MMatchmaking.Directory.cs:128.

You might have to add a few of your own classes too (like DirectoryGame, _NewOnlineGame, etc.) to preserve by managed stripping.

 

@BestHTTP thanks for the quick answer.

Unfortunately, I used the attribute [UnityEngine.Scripting.Preserve] in several script and I'm getting the same error.
I used it in : RequestEvents, HTTPUpdateDelegator, HTTPManager and two personnal script that are in the error, MMatchmaking.Directory and MMatchmaking.Command (which include MMatchmaking.Match)

 

@Ludogram The plugin doesn't require any more Preserve attributes, it already have it where would problems.

The exception happens in a HTTPRequest callback where most probably you try to parse the downloaded content (json). I don't know what's your classes look like, so i can't help too much, but you might have to add Preserve to fields/properties too. Or alternately, add the assembly+namespace to the link.xml.

 

Hi, How I can set websocket No Delay? I see webSocket.InternalRequest.TryToMinimizeTCPLatency is removed

 

@vuthang The plugin sets NoDelay for all TCP connection. WebSocket frames are sent out as soon as possible.

but not works

awaiting for response

Thanks

 

@hermit_021 Wrote a reply on Discord.

 

is it possible to have a signalr server in unity? i need to make my clients directly connect to server that can run unity features.

 

@virtouso No, not with the plugin.
