BSON

An implementation of the BSON specification in Ruby.

BSON can be installed via RubyGems:

> gem install bson

Or by adding it to your project's Gemfile:

gem 'bson'

Each release of the BSON library for Ruby after version 5.0.0 has been automatically built and signed using the team's GPG key.

To verify the bson gem file:

1. Download the GPG key.
2. Import the key into your GPG keyring with gpg --import ruby-driver.asc.
3. Download the gem file (if you don't already have it). You can download it from RubyGems with gem fetch bson, or you can download it from the releases page on GitHub.
4. Download the corresponding detached signature file from the same release. Look at the bottom of the release that corresponds to the gem file, under the 'Assets' list, for a .sig file with the same version number as the gem you wish to install.
5. Verify the gem with gpg --verify bson-X.Y.Z.gem.sig bson-X.Y.Z.gem (replacing X.Y.Z with the actual version number).

You are looking for text like "Good signature from "MongoDB Ruby Driver Release Signing Key packaging@mongodb.com" in the output. If you see that, the signature was found to correspond to the given gem file.

(Note that other output, like "This key is not certified with a trusted signature!", is related to web of trust and depends on how strongly you, personally, trust the ruby-driver.asc key that you downloaded from us. To learn more, see https://www.gnupg.org/gph/en/manual/x334.html)

RubyGems' own gem signing is problematic, most significantly because there is no established chain of trust related to the keys used to sign gems. RubyGems' own documentation admits that "this method of signing gems is not widely used" (see https://guides.rubygems.org/security/). Discussions about this in the RubyGems community have been off-and-on for more than a decade, and while a solution will eventually arrive, we have settled on using GPG instead for the following reasons:

1. Many of the other driver teams at MongoDB are using GPG to sign their product releases. Consistency with the other teams means that we can reuse existing tooling for our own product releases.
2. GPG is widely available and has existing tools and procedures for dealing with web of trust (though they are admittedly quite arcane and intimidating to the uninitiated, unfortunately).

Ultimately, most users do not bother to verify gems, and will not be impacted by our choice of GPG over RubyGems' native method.

BSON is tested against MRI (2.7+) and JRuby (9.3+).

Current documentation can be found here.

To report a bug in the bson gem or request a feature:

1. Visit our issue tracker and login (or create an account if you do not have one already).
2. Navigate to the RUBY project.
3. Click 'Create Issue' and fill out all of the applicable form fields, making sure to select BSON in the Component/s field.

When creating an issue, please keep in mind that all information in JIRA for the RUBY project, as well as the core server (the SERVER project), is publicly visible.

PLEASE DO:

• Provide as much information as possible about the issue.
• Provide detailed steps for reproducing the issue.
• Provide any applicable code snippets, stack traces and log data.
• Specify version numbers of the bson gem and/or Ruby driver and MongoDB server.

PLEASE DO NOT:

• Provide any sensitive data or server logs.
• Report potential security issues publicly (see 'Security Issues' below).

If you have identified a potential security-related issue in the bson gem (or any other MongoDB product), please report it by following the instructions here.

To request a feature which is not specific to the bson gem, or which affects more than the bson gem and/or Ruby driver alone (for example, a feature which requires MongoDB server support), please submit your idea through the MongoDB Feedback Forum.

New library functionality is generally added in a backwards-compatible manner and results in new minor releases. Bug fixes are generally made on master first and are backported to the current minor library release. Exceptions may be made on a case-by-case basis, for example security fixes may be backported to older stable branches. Only the most recent minor release is officially supported. Customers should use the most recent release in their applications.

As of 2.0.0, this project adheres to the Semantic Versioning Specification.
