• Which terminal/shell are you running Git from? e.g Bash/CMD/PowerShell/other

Bash/CMD

• What commands did you run to trigger this issue? If you can provide a
  Minimal, Complete, and Verifiable example
  this will help us understand the issue.

git clone https://server.company.de/Repository.git

• What did you expect to occur after running these commands?

Cloning without errors.

• What actually happened instead?

I don't know where to start because the error message is unhelpful.

Randomly setting

   [http]
       postBuffer = 524288000

on the client and server has had no effect.

Setting GIT_HTTP_MAX_REQUEST_BUFFER to 100M from default 10M has no effect.

GIT_CURL_VERBOSE=1 does not reveal any helpful information to me.

A shallow clone works without error:

We are seeing the same thing:

Adding --depth=1 causes the failure to go away.

error: RPC failed; curl 56 Failure when receiving data from the peer

This error looks a bit different than

error: RPC failed; curl 56 OpenSSL SSL_read: SSL_ERROR_SYSCALL, errno 0

though.

In any case, maybe switching to the Secure Channel backend via git config http.sslBackend schannel helps?

[Balkoth]

On my client and server this is already in the C:\Program Files\Git\etc\gitconfig:

Oddly enough, I was having the same Issue when I need to clone "googletest" as part of my make file build. (cmake ..)

Failed to clone 'third-party/google-test'. Retry scheduled
Cloning into '/home/user/openfhe-development/third-party/google-test'...
error: RPC failed; curl 56 GnuTLS recv error (-110): The TLS connection was non-properly terminated.

Attempting to install the submodule with

git submodule update --init --depth=1

seems to work (bypass the GnuTLS error), yet when I proceed onwards to actually building the program files, I now obtain a sort of error (see openfheorg/openfhe-development#409) which I would have not got if everything ran smoothly from the start (I verified this by attempting to set up the program files on a different machine)

Having that version on both the server and the client.

[Balkoth]

Same with git version 2.47.1.windows.2

error: RPC failed; curl 56 schannel: server closed abruptly (missing close_notify)

[dscho]

Same with git version 2.47.1.windows.2

error: RPC failed; curl 56 schannel: server closed abruptly (missing close_notify)

This suggests to me that there is either a proxy or the server itself that enforce some sort of timeout, and that the sheer amount of data is the issue (which would be consistent with the report that shallow clones work: That reduces the amount of data to be transferred).

[Balkoth]

I don't think the Server itself hosting git-http-backend.exe is enforcing some timeout or else the complete clone would fail and not some command inside the clone chain.

As in my OP i already tried raising some limits that came up on a google search. If you have any input on what and where to configure then please advise.

Also let me know if you need more information on how to diagnose what is going on.

[dscho]

i already tried raising some limits that came up on a google search.

I suspect that there is nothing you can do locally, as it was the server that hung up unexpectedly, not the client.

I don't think the Server itself hosting git-http-backend.exe is enforcing some timeout or else the complete clone would fail and not some command inside the clone chain.

The command inside the clone chain that fails is on the local side. If it was Git itself that hung up, it would most likely send an error message first. To me, that indicates that it is the web server itself, or a proxy (such as a load-balancing proxy) that just cuts off the communication. In other words, my impression is that the problem is not at the application level, but at the transport level.

Also let me know if you need more information on how to diagnose what is going on.

Unfortunately I do not really have anything useful to say here. I would stab in the dark, just like you, for example trying to figure out whether this happens after the clone takes a specific number of seconds, or after a specific number of bytes was transferred. I would try to contact the administrator of the server and ask them to look in the server logs whether they can see anything unusual that would explain the symptoms.

[Balkoth]

The server administrator sent me this saying there is nothing in it that suggests the server itself is acting up:

[Balkoth]

So who is to ask about "fixing" this issue? How can we diagnose what the culprit might be? Sticking our head in the sand and hope this just goes away is not an option.

I understand that you want to see this problem solved, and I understand that you are so frustrated that you say things like "Sticking our head in the sand and hope this just goes away is not an option".

Unfortunately, such statements do very little to motivate people like me to set aside projects they deem more important just to assist you with your problems.

If I were you, I would try to become expert enough in Secure Channel and cURL to understand what "missing close_notify" is supposed to mean, and I would study the output of GIT_TRACE_CURL=1 to the extent that I'd understand what is going on there and hope that it will help me figure out a way to solve the problem.

This is the extent of assistance I am willing to provide here, and just to be clear: I consider it my responsibility to fix this.

[Balkoth]

This was not directed to you, rather than at me trying to help understand what is going on. GIT_TRACE_CURL=1 is new to me maybe i get better results to see what's going on than with GIT_CURL_VERBOSE=1. I really would like to help in getting this fixed.
