Git server doesn't work with Win32-OpenSSH. Enclosed, please find three defects which I isolated and worked around..

[razrjk]

I pulled version: 0.0.14.0 on May 19. I just fetched version: 0.0.15.0 (June 4) today to compare. I don't believe the below issues have been corrected.

Git using Win32-OpenSSH ssh server runs as a nopty service. There are two defects in the nopty code:

1) shell-host.c passes through to cmd.exe, single quotes as literals. The literal single quotes become part of the file path name, resulting in an incorrect file path. 2) The service loop in shell-host.c, which passes its stdin to the child stdin is coded with incorrect file handles. Part of the input is currently passed back to sshd.

A temporary workaround for issue 1 is to replace all single quotes with double quotes just before the call to invoke cmd /c:

Finally, there is defect and debug issue in signal_sigchld.c. The zombied children count can become too large, which causes a seg fault. When debugging sshd.exe /ddd, debug3() is writing during signal processing which corrupts the stack. Debug3() should not write while running on an exception frame.

I'm running on Windows 10 and Windows 7 systems.

Extreme care must be taken with search paths when debugging a git server using ssh protocol on Windows, especially if cygwin and mingw, etc., are also installed on the system This is true for the client and server side. Multiple executables for ssh, sshd, and git commands can cause problems if close attention is not paid to search paths.

[manojampalam]

Thanks for the detailed report and proposed changes. Found some details here on how to setup Git server using over SSH - https://www.systutorials.com/366/set-up-git-server-through-ssh-connection/

[razrjk]

Re: shell-host.c Git push was still failing.

It appears that the whole nopty implementation assumes a pty control stream. Yet nopty may be a binary data stream. While I'm uncertain about the defaults and all the possible options of ssh (for instance, assuming pty control for a nopty connection), tty control should not be processed on a binary data stream.

After removing the pty processing from: start_withno_pty(wchar_t *command) Git push works.

I can now clone repos over ssh and push changes to them. I will continue to test.

The whole send to child inner loop simplifies to:

        while(rd){
            GOTO_CLEANUP_ON_FALSE(WriteFile(child_pipe_write, buf + i, rd, &wr, NULL));
            rd = rd - wr;
            i = i + wr;     
        }

[manojampalam]

What repo are you working on? There were changes around this logic as part of fixing https://github.com/PowerShell/Win32-OpenSSH/issues/658 Take a look at the PR, binary streaming over stdin should work with the latest changes included in v0.0.15.0.

[razrjk]

The repo is git@github.com:PowerShell/Win32-OpenSSH.git. I cloned, built, and tried to test v.0.0.15.0.

Issue 1) from my initial post is still a problem. The file path sent by git contains literal single quote characters which become part of the file path, so the path is invalid.

The remote repo in the following case is: localhost:D:\work\git_repo.git. Note the single quotes below. They may look like a double quote, but they are single quotes around single quotes. The inside single quotes are literals in the file path.

$ git ls-remote
fatal: ''d:/work/git_repo.git'' does not appear to be a git repository
fatal: Could not read from remote repository.

I also originally tried powershell.exe and bash.exe. None of the command line interpreters liked the literal single quotes when passed with the "/c" or "-c" option. cmd.exe works okay with double quotes, so I stopped looking for another solution to the problem.

Regarding issue 2) of my original post: I do see quite a few changes, but the writes to pipe_out are still going back to the sshd process, not the child process child_pipe_write handle. Next, unless ssh options are mapped directly to cmd.exe options, I don't see how you can possibly detect any sub-mode of nopty, When the pipe is nopty, it's binary. A shell with tty capabilities would need to look at the binary stream and implement any tty escapes, not shell-host.c. After starting the process (cmd.exe), shell-host.c must simply get out of the way and let the binary data flow, in both directions.

Also, sshd.exe /ddd is still broken.

[razrjk]

I finally resolved another problem with large binary transfers, typical of a big git push.

shell-host.c is currently using cmd.exe. cmd.exe was dropping the end of large binary streams over slow network connection. I tried bash.exe and powershell.exe as command interpreters and they do not drop any of the stream. It took quite a long time to discover that cmd.exe was the problem.

I settled on using powershell.exe because it acts like cmd.exe for gitExtension file path resolution and resolves the common forms of path for Windows:

ssh://<host1>://<host2>/<repo-path>
<host2>:<drive>:/<repo-path>

[joeyaiello]

@razrjk as an FYI, we do code work out of https://github.com/PowerShell/openssh-portable, and only take drops back to this repo when we do releases.

[manojampalam]

@razrjk please submit a PR on https://github.com/PowerShell/openssh-portable for the proposed changes. Also open a new issue for sshd.exe -ddd

Also add details on where you installed Git for Windows from.

[diogocp]

To work around this issue, you can run the following commands in your local repository:

git config --local remote.origin.receivepack "powershell git receive-pack"
git config --local remote.origin.uploadpack "powershell git upload-pack"

Replace origin with the name of the Windows-hosted remote.

After this you should be able to pull and push normally (works for me, anyway).

Make sure you don't select "Use Git from Git Bash only" when installing Git on the Windows server, otherwise Git won't be in the PowerShell path.

[diogocp]

After further testing, I still get an error (early EOF) when pushing binary files. This is with v0.0.17.0.

[razrjk]

That's  because it went through cmd to call powershell. I spent a day isolating the problem. My powershe'll bases ssh git server is working great!

[bingbing8]

@razrjk, I start looking this. Could you please share more information so I can try it from end to end?

1. Can you share the steps you setup the git client? Are you using the git client for window from this link? or a unix client?
2. Can you share the steps you set up git server over win32_openssh?(steps to setup git server and steps to config sshd so it talk to the git server)
3. The git commands you repro the problems ( connect from your client to the git server over sshd)

[razrjk]

1) Yes. Git for Windows with the mingw unix tools also installed. The ssh client doesn't matter (except to know which one is being used for debugging purposes). I've used several different combinations: OpenSSH, cygwin, Git ssh, Git putty. 2) It has been a while since I got everything working. Attached are my raw notes, there is some random information in these notes. notes.txt 3) With the fixes I described in this thread, my systems have been working, so I have no problems. I'm responding to let you know that the fixes worked, and similar fixes need to be added to the OpenSSH repo. We use OpenSSH sshd with Git now, all the time in our production development.

Above, I described three problems with the sshd nopty path (as of the date above - some of these problems may have been resolved. I have not pulled and rebuilt for a long time): 1) File/path escapes did not work for Windows files/paths. The problem was corrected as described above. 2) Data was being echoed back to sshd from cmd.exe because some file handles were incorrect. 3) Finally, cmd.exe does not work for large streamed data. The pipe breaks under heavy traffic load. This is a difficult problem to isolate. I finally decided to use Powershell instead of cmd.exe to work around this problem (for nopty), and it is working great.

My Git repo paths take the form:

> ssh://<opensshd-host>:<port>//<git-host>/<Git_Repo>
ssh://<opensshd-host>:<port>//<git-host>/<Git_Repo>

This supports efficient transfer between sites using Git compression over ssh, and yet the sshd server can use all the different types of Windows file path syntax. The double "//" in the path looks unusual, but it works.

My systems are using Windows Active Directory and all accounts are domain accounts, validated by the Domain Controller.

Interactive ssh/sshd work as well.

[bingbing8]

@razrjk, my remote repo is setup at d:\testgit\myrepo.git on hostmachine. How do you specify the url for the path to your repo. I always see a '/' prefix at my URL. How do you remove it? I use this command:

git clone ssh://username@domain@hostmachine/D:/testgit/myrepo.git
Cloning into 'myrepo'...
fatal: ''/D:/testgit/myrepo.git'' does not appear to be a git repository
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Here is the ssh log: debug1: Sending command: git-upload-pack '/D:\testgit\myrepo.git' debug2: channel 0: request exec confirm 1 debug3: send packet: type 98 debug2: callback done debug2: channel 0: open confirm rwindow 0 rmax 32768 debug2: channel 0: rcvd adjust 2097152 debug3: receive packet: type 99 debug2: channel_input_status_confirm: type 99 id 0 debug2: exec request accepted on channel 0 debug2: channel 0: rcvd ext data 73 fatal: ''/D:\testgit\myrepo.git'' does not appear to be a git repository

[diogocp]

Try git clone username@domain@hostmachine:D:/testgit/myrepo.git.

You will probably continue to get the "does not appear to be a git repository" error after that, because of the way that cmd.exe handles single quotes (notice that there are two sets of single quotes around ''/D:/testgit/myrepo.git'' in the error message). That is the first problem that @razrjk identified.

If you want to try my workaround, you can do it this way:

git init myrepo
cd myrepo
git remote add origin username@domain@hostmachine:D:/testgit/myrepo.git
git config --local remote.origin.uploadpack "powershell git upload-pack"
git fetch origin

[bingbing8]

@diogocp Thanks. yes, git clone username@domain@hostmachine:D:/testgit/myrepo.git works. your workaround works too. I am looking at the first issue @razrjk reported.

[bingbing8]

@diogocp how do you specify the port if you are not using the default 22? git clone username@domain@hostmachine:47003:D:/testgit/myrepo.git does not work.

[diogocp]

@bingbing8 I would set it in ~/.ssh/config. Another alternative would be to set the environment variable GIT_SSH_COMMAND="ssh -p 47003". I didn't test that, but it should work.

[bingbing8]

@diogocp, I don't repro the issues when pushing binary files (I use an executable file). I add the path to git-upload-pack to the system environment variable %Path% on host machine. Did you try on 0.0.20.0?

[diogocp]

Yes, I tried on 0.0.20.0. However, this does not happen with all binary files.

@razrjk seems to think it is related to the size of the data ("cmd.exe does not work for large streamed data. The pipe breaks under heavy traffic load."). I have some doubts about this theory because:

1. I have seen it succeed when pushing tens of megabytes and fail on pushes of less than 1 MB.
2. When it fails, it seems to fail consistently, no matter how many times you retry. It also doesn't seem to be affected by network speeds.

You should be able to consistently reproduce it this way (at least I can):

git clone https://github.com/PowerShell/Win32-OpenSSH.git
git init newrepo
cd Win32-OpenSSH
git remote add newrepo localhost:path/to/newrepo
git config --local remote.newrepo.receivepack "powershell git receive-pack"
git push newrepo

[diogocp]

Here is a simpler alternative. Try pushing this 28K file: https://repo.gradle.org/gradle/libs-releases-local/org/gradle/gradle-wrapper/4.1/gradle-wrapper-4.1.jar

[razrjk]

Diogo, By "heavy traffic load" I mean large transfer over a weak internet connection.  This is why it was difficult to isolate the problem.  cmd.exe did not work, powershell.exe does.  When you isolate the problem down to seeing that the pipe is breaking in cmd.exe for no apparent reason, then you will know. Consider that you may have another problem if it is failing all the time.

[razrjk]

I want to clarify a point. I'm not sure how the development has proceeded recently. To use powershell in the nopty path, you must change the sshd source code use use it. The shell is specified in shell-host.c. If you do not do this, and instead pass powershell as the shell on a command line, then cmd.exe will invoke powershell.exe and you will not have removed cmd.exe from the workflow.

[diogocp]

After doing some more testing, it looks like the failures are not consistent after all. The file that I meantioned above (gradle-wrapper-4.1.jar) failed every time, but after trimming it to around 4100-4200 bytes it starts failing randomly. Less than that and it always succeeds. It's really weird. The transfer seems to always complete in any case, the error is during the unpacking.

@razrjk this happens even when pushing to a remote on localhost. Also, do you have any idea why Git behaves like this while scp works perfectly?

[bingbing8]

@diogocp, did you repro the binary push with powershell launched in shell-host or the cmd?

[diogocp]

I didn't patch anything, I just installed it using chocolatey.

[bingbing8]

@diogocp my question is that did you set the following config to use powershell when repro the issue? I assume yes; otherwise you will see the single quotes issue. git config --local remote.origin.receivepack "powershell git-receive-pack" git config --local remote.origin.uploadpack "powershell git-upload-pack"

[diogocp]

@bingbing8 yes, that's what I did.

[bingbing8]

@diogocp, after that config to use powershell, push of file gradle-wrapper-4.1.jar works for me. I will try more variation.

[diogocp]

That's interesting. I've tried it dozens of times, creating new repositories (local and remote) each time, and it always fails. I've also tried this on two different machines, one running Windows Server 2008 R2 and the other Windows 10.

I'll see if I can reproduce it in a VM later.

[bingbing8]

@razrjk, could you share your code changes to launch powershell in shell-host.c? I don't see the difference between pass "powershell git receive-pack" as command. The code path this line. Did you pass "C:\Windows\System32\WindowsPowerShell\v1.0" as the module name of CreateProcessW? ret = CreateProcessW(NULL, command, NULL, NULL, TRUE, 0, NULL, NULL, &si, &pi);

[razrjk]

The short answer is yes. Invoke Powershell instead of cmd.exe.

The code changed in this area since my last pull. This code is/was in start_withno_pty(). You want to avoid having cmd.exe in variable cmd (which is variable command in your version), or you will "cmd.exe powershell.exe", which leaves cmd.exe in the execution pipeline.

    /*TODO - pick this up from system32*/
    cmd[0] = L'\0';
    GOTO_CLEANUP_ON_ERR(wcscat_s(cmd, MAX_CMD_LEN, L"powershell.exe"));
    if (command) {
        GOTO_CLEANUP_ON_ERR(wcscat_s(cmd, MAX_CMD_LEN, L" /c"));
        GOTO_CLEANUP_ON_ERR(wcscat_s(cmd, MAX_CMD_LEN, L" "));
        //GOTO_CLEANUP_ON_ERR(wcscat_s(cmd, MAX_CMD_LEN, L"'\\''"));

        int i = 0;
        while (command[i] != L'\0')
        {
            if (command[i] == L'\'' )
                command[i] = L'\"';
            i++;
        }

        GOTO_CLEANUP_ON_ERR(wcscat_s(cmd, MAX_CMD_LEN, command));
        //GOTO_CLEANUP_ON_ERR(wcscat_s(cmd, MAX_CMD_LEN, L"'\\''"));

//      fflush(stderr);
    }

    GOTO_CLEANUP_ON_FALSE(CreateProcess(NULL, cmd, NULL, NULL, TRUE, 0, NULL, NULL, &si, &pi));

[bingbing8]

@razrjk, the code block you share won't be hit in the latest code in this scenario because even no matter set "powershell git receive-pack" workaround or not, it will launch command as is first without adding any prefix. run_under_cmd is set to false so it won't reach the code you changed.

/* Try launching command as is first */
if (command) {      
    ret = CreateProcessW(NULL, command, NULL, NULL, TRUE, 0, NULL, NULL, &si, &pi); 
    if (ret == FALSE) {
        /* it was probably this case - ssh user@target dir */
        if (GetLastError() == ERROR_FILE_NOT_FOUND)
            run_under_cmd = TRUE;
        else
            goto cleanup;
    }
}
else
    run_under_cmd = TRUE;

/* if above failed with FILE_NOT_FOUND, try running the provided command under cmd*/

@bingbing8, Okay. That should resolve the cmd.exe issue. If you are still having problems, attached is my shell-host.c file. It is working for me.

@diogocp, after setting the workaround, pushing of the file gradle-wrapper-4.1.jar always works no matter single box or multi-machines. I also tried two physical machines. What is your client setting? I tried both $env:GIT_SSH_COMMAND = '"C:\OpenSSH\ssh.exe" -T' $env:GIT_SSH_COMMAND = '"C:\OpenSSH\ssh.exe" ' I want to find out you are using tty or notty on shellhost when you repro the issue What error do you get? I see this error once when push a 900k file, but the file is uploaded successfully. re-push the same file works fatal: protocol error: bad line length character: ok

warning: remote reported status on unknown ref: refs/heads/m0000un fatal: protocol error: bad line length character: pack

Is this the error you see?

[bingbing8]

@razrjk, thanks for the details issues reported and steps to help to identify the problems.

1. For the single quotes issue, we are still thinking different approach to fix on server. We recommend people to apply the temporary workaround before the fix on server.
2. I reviewed the handle you mentioned in file shell-host, some lines pass its stdin to the pipe_out, they are on purpose. This is for echo the input to client. especially when interop with putty, which does not echo the input in client side. If you review the code, all the stdin eventually pass to child write handle too.
3. sshd.exe /ddd issue got fixed and will be available in 0.0.21.0.
4. we need the control stream in no pty. for the case where run "cmd /c XXXX", we need to echo the input back and process those input before pass to child write handle.

@diogocp I made some changes in shell-host.c. Please let me know if you still repro the big binary push issue after the fix.

I posted a Setting up a Git server on Windows using Git for Windows and Win32_OpenSSH. please let me know if you see any other issue.

[HrochL]

Hi All, about "single quotes issue" - recomended workaround must be applied on each client. This is not good thing for a common use. I would argue for some solution on the server ... ideally for the option to choosing the shell.

[bingbing8]

@HrochL , yes, it is a temporary workaround until we have a good fix on the server.

[bingbing8]

@benvindo which step? this? To check out a repository, go to where you want to put your local repo,

 cd c:\mygitrepros
 # initialize a local repo folder
 git init mylocalrepo
 cd mylocalrepo
 # add the remote repro
 git remote add origin user@domain@servermachine:C:/test/myrepo.git
 # work around the known issue by launching powershell to run the git commands
 git config --local remote.origin.uploadpack "powershell git-upload-pack"
 git config --local remote.origin.receivepack "powershell git-receive-pack"
 git fetch origin

[bingbing8]

Move this issue to Beta until we have a proper fix on server

[benvindo]

@bingbing8 I don't understand first step in server. I tried following some steps for configuration my remote git but unsuccessful. when add remote like this and run git push: git remote set-url --add--push origin ssh://bruno.costa@b2t.corp@R2D2:/C:/web/multiprodutos/repo/homol.git

The cause of error above was I don't put environment 'git\mingw64\bin' in my variables env in server, however I got other error: fatal: '/C:/web/multiprodutos/repo/homol.git' does not appear to be a git repository fatal: Could not read from remote repository.

**When I put remote without slash in the start as recommended git remote set-url --add--push origin ssh://bruno.costa@b2t.corp@R2D2:C:/web/multiprodutos/repo/homol.git I can't even log in

There is no ssh:// in the instructions.

Hi, sorry for my lack of attention, I was focused on connecting the apps and forgetting the minimally details, Now its work perfectly. Thanks!!

@diogocp, can you try the [latest release] (https://github.com/PowerShell/Win32-OpenSSH/releases/tag/v0.0.21.0) if you can repro early EOF error.

[diogocp]

@bingbing8 yes, same error with 0.0.21.0.

[bingbing8]

@diogocp, I really can't repro it. what do you get in the client log?

[benvindo]

I have a similar error to @diogocp, at some point when a member of my team sends commits to a TFS repository and after some time we try to send all the commits to the production happens the error:

`git push serve_prod homol:prod

@benvindo which step? this? To check out a repository, go to where you want to put your local repo,

 cd c:\mygitrepros
 # initialize a local repo folder
 git init mylocalrepo
 cd mylocalrepo
 # add the remote repro
 git remote add origin user@domain@servermachine:C:/test/myrepo.git
 # work around the known issue by launching powershell to run the git commands
 git config --local remote.origin.uploadpack "powershell git-upload-pack"
 git config --local remote.origin.receivepack "powershell git-receive-pack"
 git fetch origin

I follow your approach but I still get the fatal: ''/C:/git/A.git'' does not appear to be a git repository when I try to git clone the remote repository from another server. I am really confused about this ....

[diogocp]

@larry191994 you cannot use git clone directly. You have to follow those instructions every time you want to fetch the repository.

@larry191994 , @diogocp , after supporting default shell, you don't need the above workaround if you can set up Default Shell. Please refer to the link.
