jj git over ssh fails with sha-1 key #440

Description

I'm not sure if there's some magic that's happening that allows git to clone an ssh+git repo with a SHA-1 key, but jj won't, but it happens every time. Not that SHA-1 keys are good, just that enforcement seems to be different from git.

Steps to Reproduce the Problem

  1. ssh-add -L | grep ssh-rsa returns a key.
  2. jj git remote add origin git@github.com:<username>/jj.git
  3. jj git fetch

Expected Behavior

❯ jj git fetch
Nothing changed.

Actual Behavior

❯ jj git fetch 
Error: Unexpected git error when fetching: ERROR: You're using an RSA key with SHA-1, which is no longer allowed. Please use a newer client or a different key type.
Please see https://github.blog/2021-09-01-improving-git-protocol-security-github/ for more information.

; class=Ssh (23); code=Eof (-20)

git clone/git fetch with the same URL works fine.

Specifications

  • Platform: Linux
  • Version: HEAD-980004e (latest main branch as of a few minutes ago)

Thanks for the report. I'm pretty sure that's a limitation of our very naive support for authentication. That's documented here and implemented here. In short, we only support a password-less key called exactly ~/.ssh/id_rsa as well as ssh-agent. Maybe the difference between Git is that you have also have e.g. an ed25519 key that's picked up by Git?

I recommend using ssh-agent even once we've improved the authentication support.

Yep, ssh-agent forwarded remotely.

This does look like something upstream, given how thin the wrap is around authentication there. Espeically since the error message does seem to be the upstream github message. I looked at git2 and libssh2's changelogs, and nothing jumped out about SHA-1. It does look like there's two years of upsdates to libssh2's wrapper since the version in libgit2-sys's Cargo.toml.

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>
```

With a grain of salt, but most of these problems should be fixed (or at least checked if they are fixed). They are the ones listed in jj-vcs#4979 .

```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>

bsdinis added a commit to bsdinis/jj that referenced this issue Jan 18, 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 --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.
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>

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

 - 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>

bsdinis added a commit to bsdinis/jj that referenced this issue Jan 23, 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

 - 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>
