# registry-backup
A command line utility for downloading all .crate files hosted by a Cargo registry server.
Use cases:
- **Backup:** retrieve a registry server's files for backup storage
- **Export:** pull the files so you can host them at another registry server
## Runtime Options
```console
$ ./target/release/registry-backup --help
registry-backup 0.2.0
Jonathan Strong <jstrong@shipyard.rs>
Download all .crate files from a registry server
USAGE:
registry-backup [OPTIONS]
OPTIONS:
--index-url <INDEX_URL>
URL of the registry index we are downloading .crate files from. The program expects that
it will be able to clone the index to a local temporary directory; the user must handle
authentication if needed
--index-path <INDEX_PATH>
instead of an index url, just point to a local path where the index is already cloned
-p, --output-path <PATH>
Directory where downloaded .crate files will be saved to [default: output]
-u, --user-agent <USER_AGENT>
Value of user-agent HTTP header [default: registry-backup/v0.2.0]
--requests-per-second <REQUESTS_PER_SECOND>
Requests to registry server will not exceed this rate [default: 25]
--max-concurrent-requests <MAX_CONCURRENT_REQUESTS>
Independent of the requests per second rate limit, no more than
`max_concurrent_requests` will be in flight at any given moment [default: 10]
-a, --auth-token <AUTH_TOKEN>
If registry requires authorization (i.e. "auth-required" key is set to `true` in the
`config.json` file), the token to include using the Authorization HTTP header
-c, --config-file <CONFIG_FILE>
Specify configuration values using the provided TOML file, instead of via command line
flags. The values in the config file will override any values passed as command line
flags. See config.toml.sample for syntax of the config file
-h, --help
Print help information
-V, --version
Print version information
```
## Configuration File
A toml configuration file may be used instead of command line flags. A sample file (`config.toml.sample`) is included. From the example file:
```toml
# index repo url
index-url = "ssh://git@ssh.shipyard.rs/shipyard-rs-public/crate-index.git"
# alternatively, specify a local dir
# index-path = "/path/to/cloned/index"
[http]
user-agent = "registry-backup/v0.1.0"
requests-per-second = 40
max-concurrent-requests = 20
[output]
path = "output"
format = "/{crate}/{version}/download"
# auth-token = "xxx"
```
## Justfile
The repository includes a `justfile` with functionality for building, testing, etc.
Included commands:
```console
$ just --list
Available recipes:
cargo +args='' # cargo wrapper; executes a cargo command using the settings in justfile (RUSTFLAGS, etc.)
check +args='' # cargo check wrapper
debug-build +args='' # cargo build wrapper - builds registry-backup in debug mode
generate-readme # generate updated README.md
get-crate-version
pre-release # check, run tests, check non-error output for clippy, run rustfmt
release
release-build +args='' # cargo build --release wrapper - builds registry-backup in release mode
release-prep
test +args='' # cargo test wrapper
verify-clean-git # verify no uncommitted changes
```
The commands that mirror cargo commands (e.g. `just test`) are included for the purpose of convenience, so that various options (e.g. `RUSTFLAGS='-C target-cpu=native`) can be included without typing them out each time.
There are several variables defined in the `justfile` which pertain to rust build settings:
```
rustc-version
## Generating README.md
This file is generated using a template (`doc/README.tera.md`) rendered using updated outputs of the CLI menu, config sample, and other values.
This version of README.md was generated at `Thu, 08 Sep 2022 21:32:44 +0000` based on git commit `a6d6f5a0`.
To (re-)generate the README.md file, use the justfile command:

registry-backup 0.2.0
Jonathan Strong <jstrong@shipyard.rs>
Download all .crate files from a registry server
USAGE:
registry-backup [OPTIONS]
OPTIONS:
--index-url <INDEX_URL>
URL of the registry index we are downloading .crate files from. The program expects that
it will be able to clone the index to a local temporary directory; the user must handle
authentication if needed
--index-path <INDEX_PATH>
instead of an index url, just point to a local path where the index is already cloned
-p, --output-path <PATH>
Directory where downloaded .crate files will be saved to [default: output]
-u, --user-agent <USER_AGENT>
Value of user-agent HTTP header [default: registry-backup/v0.2.0]
--requests-per-second <REQUESTS_PER_SECOND>
Requests to registry server will not exceed this rate [default: 25]
--max-concurrent-requests <MAX_CONCURRENT_REQUESTS>
Independent of the requests per second rate limit, no more than
`max_concurrent_requests` will be in flight at any given moment [default: 10]
-a, --auth-token <AUTH_TOKEN>
If registry requires authorization (i.e. "auth-required" key is set to `true` in the
`config.json` file), the token to include using the Authorization HTTP header
-c, --config-file <CONFIG_FILE>

flags. The values in the config file will override any values passed as command line
flags. See config.toml.sample for syntax of the config file
