Description

I'm currently unable to clone or fetch from repos hosted on Sourcehut with JJ on my Windows device using SSH, but it works without JJ. I thought this might be due to #3322 as I was previously getting the same error with Gituhb, but I was able to bypass it by first connecting with ssh -o HostKeyAlgorithms=ssh-rsa "[email protected]" to force it to populate a known_hosts entry with RSA. After that, jj git clone and others worked fine.

This workaround does not work for Sourcehut. It appears that ssh-rsa isn't a valid host key algorithm for Sourcehut:

PS C:\Users\Kelly\Projects> ssh -o HostKeyAlgorithms=ssh-rsa "[email protected]"
Unable to negotiate with 46.23.81.155 port 22: no matching host key type found. Their offer: rsa-sha2-512,rsa-sha2-256,ecdsa-sha2-nistp256,ssh-ed25519

I've tried all of the offered key algorithms (wiping known_hosts again every time) and none of them seem to let jj successfully clone. I'm not sure if this is related to #1419 and is a regression with RSA keys for Sourcehut, or whether it's the same issue as #3322 and that none of the algos offered by Sourcehut are valid workarounds.

Please let me know if there's any other information I can provide or any workarounds I can try. I'll try to find time later to test out #3554 as well and see if it resolves this issue.

Steps to Reproduce the Problem

  1. (Optional, gives a different error message) Run ssh -o HostKeyAlgorithms=rsa-sha2-512 "[email protected]" to add a ssh-rsa entry for Sourcehut to known_hosts
  2. Try to clone a repo hosted at [email protected].

Expected Behavior

Repo should clone

Actual Behavior

Without an entry:

Error: invalid or unknown remote ssh hostkey; class=Ssh (23); code=Certificate (-17)
Hint: Jujutsu uses libssh2, which doesn't respect ~/.ssh/config. Does `ssh -F /dev/null` to the host work?

With an entry in known_hosts:

Error: failed to start SSH session: Unable to exchange encryption keys; class=Ssh (23)
Hint: Jujutsu uses libssh2, which doesn't respect ~/.ssh/config. Does `ssh -F /dev/null` to the host work?

Specifications

From the version string it looks like you're using a self-compiled version of jj? Can you try using the jj.exe found on the 0.23.0 release page from Wednesday? By default the releases are built against OpenSSL so they should have support for ECDSA/Ed25519, while compiling yourself results in a binary that links against Windows CNG subsystem, which does not support Ed25519 at the very least (though I'd expect ECDSA to work...)

I got this version from the jj.exe in the jj-v0.23.0-x86_64-pc-windows-msvc.zip file on the release page. I copied it directly over the jj.exe obtained from winget install martinvonz.jj. The 0.18 version from the winget install gave me the same results.

Like most SSH issues (and some others), this should be fixed by #5228. You could trying with a build from that PR (don't forget to set the config mentioned there).

bsdinis added a commit to bsdinis/jj that referenced this issue Jan 10, 2025
Reasoning:

`jj` fails to push/fetch over ssh depending on the system.
Issue jj-vcs#4979 lists over 20 related issues on this and proposes spawning
a `git` subprocess for tasks related to the network (in fact, just push/fetch
are enough).

This PR implements this.
Users can either enable shelling out to git in a config file:

```toml
[git]
subprocess = true
```

Implementation Details:

This PR implements shelling out to `git` via `std::process::Command`.
There are 2 sharp edges with the patch:
 - it relies on having to parse out git errors to match the error codes
   (and parsing git2's errors in one particular instance to match the
   error behaviour). This seems mostly unavoidable

 - to ensure matching behaviour with git2, the tests are maintained across the
   two implementations. This is done using test_case, as with the rest
   of the codebase

Testing:

Run the rust tests:
```
$ cargo test
```

Build:
```
$ cargo build
```

Clone a private repo:
```
$ path/to/jj git clone --shell <REPO_SSH_URL>
```

Create new commit and push
```
$ echo "TEST" > this_is_a_test_file.txt
$ path/to/jj describe -m 'test commit'
$ path/to/jj git push --shell -b <branch>
```

bsdinis added a commit to bsdinis/jj that referenced this issue Jan 12, 2025
Reasoning:

`jj` fails to push/fetch over ssh depending on the system.
Issue jj-vcs#4979 lists over 20 related issues on this and proposes spawning
a `git` subprocess for tasks related to the network (in fact, just push/fetch
are enough).

This PR implements this.
Users can either enable shelling out to git in a config file:

```toml
[git]
subprocess = true
```

Implementation Details:

This PR implements shelling out to `git` via `std::process::Command`.
There are 2 sharp edges with the patch:
 - it relies on having to parse out git errors to match the error codes
   (and parsing git2's errors in one particular instance to match the
   error behaviour). This seems mostly unavoidable

 - to ensure matching behaviour with git2, the tests are maintained across the
   two implementations. This is done using test_case, as with the rest
   of the codebase

Testing:

Run the rust tests:
```
$ cargo test
```

Build:
```
$ cargo build
```

Clone a private repo:
```
$ path/to/jj git clone --shell <REPO_SSH_URL>
```

Create new commit and push
```
$ echo "TEST" > this_is_a_test_file.txt
$ path/to/jj describe -m 'test commit'
$ path/to/jj git push --shell -b <branch>
```

bsdinis added a commit to bsdinis/jj that referenced this issue Jan 15, 2025
Reasoning:

`jj` fails to push/fetch over ssh depending on the system.
Issue jj-vcs#4979 lists over 20 related issues on this and proposes spawning
a `git` subprocess for tasks related to the network (in fact, just push/fetch
are enough).

This PR implements this.
Users can either enable shelling out to git in a config file:

```toml
[git]
subprocess = true
```

Implementation Details:

This PR implements shelling out to `git` via `std::process::Command`.
There are 2 sharp edges with the patch:
 - it relies on having to parse out git errors to match the error codes
   (and parsing git2's errors in one particular instance to match the
   error behaviour). This seems mostly unavoidable

 - to ensure matching behaviour with git2, the tests are maintained across the
   two implementations. This is done using test_case, as with the rest
   of the codebase

Testing:

Run the rust tests:
```
$ cargo test
```

Build:
```
$ cargo build
```

Clone a private repo:
```
$ path/to/jj git clone --shell <REPO_SSH_URL>
```

Create new commit and push
```
$ echo "TEST" > this_is_a_test_file.txt
$ path/to/jj describe -m 'test commit'
$ path/to/jj git push --shell -b <branch>
```

a `git` subprocess for tasks related to the network (in fact, just push/fetch
are enough).

This PR implements this.
Users can either enable shelling out to git in a config file:

```toml
[git]
subprocess = true
```

Implementation Details:

This PR implements shelling out to `git` via `std::process::Command`.
There are 2 sharp edges with the patch:
 - it relies on having to parse out git errors to match the error codes
   (and parsing git2's errors in one particular instance to match the
   error behaviour). This seems mostly unavoidable

 - to ensure matching behaviour with git2, the tests are maintained across the
   two implementations. This is done using test_case, as with the rest
   of the codebase

Testing:

Run the rust tests:
```
$ cargo test
```

Build:
```
$ cargo build
```

Clone a private repo:
```
$ path/to/jj git clone --config='git.subprocess=true' <REPO_SSH_URL>
```

Create new commit and push
```
$ echo "TEST" > this_is_a_test_file.txt
$ path/to/jj describe -m 'test commit'
$ path/to/jj git push --config='git.subprocess=true' -b <branch>
```

 - to ensure matching behaviour with git2, the tests are maintained across the
   two implementations. This is done using test_case, as with the rest
   of the codebase

Testing:

Run the rust tests:
```
$ cargo test
```

Build:
```
$ cargo build
```

Clone a private repo:
```
$ path/to/jj git clone --config='git.subprocess=true' <REPO_SSH_URL>
```

Create new commit and push
```
$ echo "TEST" > this_is_a_test_file.txt
$ path/to/jj describe -m 'test commit'
$ path/to/jj git push --config='git.subprocess=true' -b <branch>

bsdinis added a commit to bsdinis/jj that referenced this issue Jan 20, 2025
Reasoning:

`jj` fails to push/fetch over ssh depending on the system.
Issue jj-vcs#4979 lists over 20 related issues on this and proposes spawning
a `git` subprocess for tasks related to the network (in fact, just push/fetch
are enough).

This PR implements this.

Implementation Details:

This PR implements shelling out to `git` via `std::process::Command`.
There are 2 sharp edges with the patch:
 - it relies on having to parse out git errors to match the error codes
   (and parsing git2's errors in one particular instance to match the
   error behaviour). This seems mostly unavoidable

   (and parsing git2's errors in one particular instance to match the
   error behaviour). This seems mostly unavoidable

 - to ensure matching behaviour with git2, the tests are maintained across the
   two implementations. This is done using test_case, as with the rest
   of the codebase

Testing:

Run the rust tests:
```
$ cargo test
```

Build:
```
$ cargo build
```

Clone a private repo:
```
$ path/to/jj git clone --config='git.subprocess=true' <REPO_SSH_URL>
```

Create new commit and push
```
$ echo "TEST" > this_is_a_test_file.txt
$ path/to/jj describe -m 'test commit'
$ path/to/jj git push --config='git.subprocess=true' -b <branch>
```

Reasoning:

`jj` fails to push/fetch over ssh depending on the system.
Issue jj-vcs#4979 lists over 20 related issues on this and proposes spawning
a `git` subprocess for tasks related to the network (in fact, just push/fetch
are enough).

This PR implements this.

Implementation Details:

This PR implements shelling out to `git` via `std::process::Command`.

Just wanted to confirm that this is now working with the latest version, downloadable from the releases! Thank you :D

Note that currently the version of jj installed from winget install martinvonz.jj is 0.24, which doesn't have the aforementioned fixes. The earliest version that does is 0.26. For now I've just dropped it over the jj.exe provided by winget and that seems to work fine.
