ml-challenge

Program created for MercadoLibre coding challenge. It fetches emails from a Gmail account using POP3 protocol and persists those with the word DevOps in the subject or body.

Setup dev environment

• Install rust/cargo (https://www.rust-lang.org/es/learn/get-started)
• Install OpenSSL:
  • For linux/macOS:

    # macOS
    $ brew install [email protected]
    
    # Arch Linux
    $ sudo pacman -S pkg-config openssl
    
    # Debian and Ubuntu
    $ sudo apt-get install pkg-config libssl-dev
    
    # Fedora
    $ sudo dnf install pkg-config openssl-devel
  

  • For windows: Either install through vcpkg or download the pre-compiled binaries (https://wiki.openssl.org/index.php/Binaries)

Building/Running

To test the program you will need to have a gmail account that has POP3 enabled in the configurations and that also allows less secure apps (https://myaccount.google.com/lesssecureapps)

To build the project you can either run cargo build and use it as a console application. Running ml-challenge.exe --user <email> --pass <password> You can run it with --help to get a full description of the args.

You can also run it directly with cargo using cargo run -- --user <email> --pass <password> (Yes, you need to put two standalone dashes in the middle)

You can configure the final SQLite db name with --dbname <name>

Note for Windows users

Sometimes in windows, having OpenSSL installed is not enough for the Rust openssl-sys crate to detect the install path. Also, the binaries don't usually come with the certificates, so you can download the Mozilla CA in PEM format at https://curl.haxx.se/docs/caextract.html

If you're experiencing SSL problems, you can tell openssl-sys where to look with the following environmental variables:

OPENSSL_DIR=<dir_path>
SSL_CERT_FILE=<file_path>
