get call drops off silently without crashing or returning

[ThinkDigitalSoftware]

I'm trying to run http.get("http://audio.livekingdomhall.com:27219/stream") and the function never returns when awaited or when using a .then() call. It stops at line 171 of base_client.dart. When stepping through the debugger, that's the last line it calls before the program resumes. Any code in the function afterwards is not run, and any code in the .then() does not run either. If I don't await the call, the code after the get call runs.

Experiencing something similar as well. Sometimes it works, sometimes it doesn't....You come to any sort of resolution?

I think there could be an issue with this when using breakpoints. It seems that when I use breakpoints, http.get() will drop off silently, however, when I remove all of the breakpoints, the code seems to run fine. I'm using intelliJ. Can you confirm this ThinkDigitalRepair?

What Dart version are you using? I had similar issues that the app hung until I set/removed a breakpoint, then it continued, but I'm sure that's entirely unrelated to the http package.

The version has changed by now, I'm sure. 2.something though

Unfortunately I don't see enough information here to debug this issue.

If you can provide a minimal reproducing example feel free to re-open this issue and we can look into what is going on.

@cskau-g We are facing a similar issue and can be reproduced as below.

1. Set [HttpClient.maxConnectionsPerHost] to a non-null value n.
2. Disable all network connections.
3. Make HTTP calls. The first n calls will receive [SocketException] errors.
4. After the first n failed calls, all following calls to the same host will be dropped silently.
5. Enable network connection.
6. Calls to the same host are still being dropped silently.

A demo can be found here: https://github.com/microdog/call_dropping

After tracing into the library, I found that this might be a bug in the dart SDK:

https://github.com/dart-lang/sdk/blob/0ccdc3e/sdk/lib/_http/http_impl.dart#L1940

_connecting is increased before connectionTask.then(), and the error of connectionTask is not handled. I think _connecting should be decreased when connectionTask completed with error.

Thank you very much for the investigation, @microdog.
I see you also filed dart-lang/sdk#34477 to track this upstream, so I'll leave this issue closed (as a dupe of the upstream issue).
