I was having an issue when upgrading a Rust project from 1.46 to 1.65. The motivation for the upgrade was only to have a working build for Mac M1/M2.
First, I started by just updating to the Rust version that I setup already (that being version 1.65). I didn’t want to downgrade or install multiple versions.
I poked around at build errors and googled if anyone had a similar issue.
Prior to upgrading, the project dependencies looked like this:
[dependencies]
dirs = "2.0.2"
docopt = "1"
port_scanner = "0.1.5"
rusoto_core = "0.44.0"
rusoto_credential="0.44.0"
rusoto_ec2_instance_connect="0.44.0"
rusoto_s3 = "0.44.0"
rusoto_opsworks = { version = "0.44.0", features = ["serialize_structs"] }
tokio = "0.2.21"
serde = { version = "1", features = ["derive"] }
serde_yaml = "0.8"
serde_json = "1.0"
ssh2 = "0.5"
After:
[dependencies]
dirs = "2.0.2"
docopt = "1"
port_scanner = "0.1.5"
rusoto_core = "0.48.0"
rusoto_credential="0.48.0"
rusoto_ec2_instance_connect="0.48.0"
rusoto_s3 = "0.44.0"
rusoto_opsworks = { version = "0.48.0", features = ["serialize_structs"] }
tokio = "0.2.21"
serde = { version = "1", features = ["derive"] }
serde_yaml = "0.8"
serde_json = "1.0"
ssh2 = "0.5"
After some flailing, I noticed that somehow in the upgrading of libraries
rusoto_s3 didn’t get bumped to 0.48.0, even though the other rusoto libraries
were bumped.
After changing that, now it builds.
New error means progress!
thread 'main' panicked at 'there is no reactor running, must be called from the context of a Tokio 1.x runtime',
.cargo/registry/src/github.com-1ecc6299db9ec823/hyper-0.14.26/src/client/connect/dns.rs:121:24
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
It looks like based off of this result we need to update to tokio 1.28.
I also updated ssh2 to 0.9.4. I don’t think I hit any errors here, just updating to later versions to integrate changes and not need to do it later.
Final Cargo.toml dependencies.
[dependencies]
dirs = "2.0.2"
docopt = "1"
port_scanner = "0.1.5"
rusoto_core = "0.48.0"
rusoto_credential="0.48.0"
rusoto_ec2_instance_connect="0.48.0"
rusoto_s3 = "0.48.0"
rusoto_opsworks = { version = "0.48.0", features = ["serialize_structs"] }
tokio = "1.28"
serde = { version = "1", features = ["derive"] }
serde_yaml = "0.8"
serde_json = "1.0"
ssh2 = "0.9.4"
Build works and it’s runnable!
This was my first time upgrading a Rust project to a new Rust version, I’m happy to write that it was a relatively pain free experience after I got past the self inflicted rusoto version mismatch.
