[grpc-io] Re: gRPC Java - async client waiting forever after the server closes the connection

['Chengyuan Zhang' via grpc.io]

Can you post some code snippet for how you implement it? Also, at what 
event is "server connection has been established" you are referring to?

[grpc-io] gRPC Java - async client waiting forever after the server closes the connection

['Sri' via grpc.io]

I think I am doing something very obvious wrong. I have a bidi streaming 
grpc async client. It isn't closing the connection and waiting forever even 
after the server closed connection.
Also any messages sent on the stream before the server connection has been 
established are not received on the server after the connection is 
established.

Re: [grpc-io] Large Files not able to upload even as chunks

[vigneshdhanraj]

Thanks Thomas,

Thought like upload request needs to be bytes and for reply used int, that 
is the issue thanks a lot. Issue solved :)

Thanks Team, it is my mistake.

Re: [grpc-io] Large Files not able to upload even as chunks

[Thomas Mercier]

The maximum value of an int32 is 2,147,483,647. Why are you using a signed
type for length in the first place though?

Re: [grpc-io] Re: gRPC C++ Installation Issue

[Patrice Chalin]

+Jan Tattermusch , Eric and I discussed
the following during our Docs WG meeting: to avoid users facing this
problem again, how about if we changed the min version of cmake from the
current 3.5.1 to, say, 3.13

cmake_minimum_required(VERSION 3.13)


in either the C++ hello world cmake config:

   -
   
https://github.com/grpc/grpc/blob/master/examples/cpp/helloworld/CMakeLists.txt#L20

and/or to the (top-level) grpc cmake config?

   - https://github.com/grpc/grpc/blob/master/CMakeLists.txt#L25

(and maybe the other C++ examples too?)

Re: [grpc-io] Large Files not able to upload even as chunks

[Michael Webster]

Do you have any snippets you can share from your code?  I use python-grpc 
in another project for transferring files and I've never had an issue with 
files > 2gb, with 1mb chunks (local network operations).

Re: [grpc-io] Large Files not able to upload even as chunks

['Mya Pitzeruse' via grpc.io]

Is there an associated error on the server? The error message suggests a
server error with an index out of bounds exception: 2^31. Only way I could
see something like that happening is if the file was being buffered on the
server side in memory.

[grpc-io] Large Files not able to upload even as chunks

[grpc-io] CompletionQueue life time in a async server

[afshin . pir]

Hi all

I was wondering if I should extend lifetime of a CompletionQueue according 
to lifetime of a rpc call in a async server or it has been checked 
internally. As an example, let's check the the simple async helloworld 
server here 
.
 
Now if we assume that processing phase takes a lot of time, two situation 
may happen:

   1. Application may go into stopping phase before we try to write back 
   results. From stopping phase, I mean when Shutdown() method is called for 
   Server and CompletionQueue. What happens if I write in a CompletionQueue 
*after 
   *it is shutdown? Will they just be ignored? I found in Shutdown() docs 
   that application should not enqueue anything after shutdown is called (and 
   I suppose Write() or Finish() enqueues). Does this mean that I should 
   manually check if a CompletionQueue is shutting down via a secondary 
   flag(because I could not find anything that shows a completion queue is 
   shutting down) before doing anything? 
   2. If I have set an Alarm on my CompletionQueue, should I cancel it 
   before shutting down the CompletionQueue? Because an alarm may expire after 
   I started shutting down the queue.
   
Since grpc samples are primitive, there are a lot of conditions that is not 
checked in them and I'm not sure what exactly happens in these case. Is 
these any example for a simple rpc request that handles these conditions 
better?
