Webアプリ開発とデータベースマイグレーションには密接な関係があり、Pythonでよく採用されるDjangoやSQLAlchemyには、DBのスキーマを変更するマイグレーション機能があります。一般的に、プログラムを実装するときはリポジトリでブランチを作りそれぞれのブランチで実装作業を進めます。Webアプリの開発でも同様ですが、各ブランチでDBスキーマを変更する場合には注意が必要です。例えば、複数のブランチで同じテーブルのカラムを追加して使いたい場合や、DBスキーマの変更が競合する場合は、ブランチのマージ時に競合してしまいます。多くの機能を並行開発したり、マージするまでの期間が長い場合には、このような競合が増えてしまいます。
このトークでは、Djangoを例に、データベースマイグレーションの仕組みから、実際の開発現場で発生したトラブルとその解決方法について紹介します。

Introduction of Cybersecurity with OSS at Code Europe 2024Hiroshi SHIBATA
I develop the Ruby programming language, RubyGems, and Bundler, which are package managers for Ruby. Today, I will introduce how to enhance the security of your application using open-source software (OSS) examples from Ruby and RubyGems.
The first topic is CVE (Common Vulnerabilities and Exposures). I have published CVEs many times. But what exactly is a CVE? I'll provide a basic understanding of CVEs and explain how to detect and handle vulnerabilities in OSS.
Next, let's discuss package managers. Package managers play a critical role in the OSS ecosystem. I'll explain how to manage library dependencies in your application.
I'll share insights into how the Ruby and RubyGems core team works to keep our ecosystem safe. By the end of this talk, you'll have a better understanding of how to safeguard your code.
Long journey of Ruby Standard library at RubyKaigi 2024Hiroshi SHIBATA
Ruby has a lot of standard libraries from Ruby 1.8. I promote them democratically with GitHub today via default and bundled gems. So, I'm working to extract them for Ruby 3.4 continuously and future versions. It's long journey for me.
After that, some versions may suddenly happen LoadError at require when running bundle exec or bin/rails, for example matrix or net-smtp. We need to learn what's difference default/bundled gems with standard libraries.
In this presentation, I will introduce what's the difficult to extract bundled gems from default gems and the details of the functionality that Ruby's require and bundle exec with default/bundled gems. You can learn how handle your issue about standard libraries.

Deep dive into Ruby's require - RubyConf Taiwan 2023Hiroshi SHIBATA
Since Ruby's bundled and default gems change every year with each release, some versions may suddenly happen LoadError at require when running bundle exec or bin/rails, for example matrix or net-smtp.
In this presentation, I will introduce the details of the functionality that extends Ruby's require to provide guidance to users on what they can do to load them. And I will also show how $LOAD_PATH is build behind Ruby and Rails by Bundler.
This document contains the slides for a presentation on resolving gem dependencies in Ruby code. It discusses RubyGems and Bundler, which are package managers for Ruby that handle dependency resolution. Key terms are defined, like gem, gemspec, Gemfile, and various components involved in dependency resolution like the resolver, resolver engine, and different engines used by RubyGems and Bundler. Performance issues with RubyGems are also addressed, and how Bundler helps address them.
The document discusses resolving gem dependencies in Ruby code. It begins with an introduction to ANDPAD and then defines key terms related to package managers and gem dependency resolution. It describes the architecture of RubyGems and Bundler and some current issues, such as performance problems and cases where `bundle update` or `gem install` do not work as expected. Deep dives are provided into specific cases to explain underlying causes.
How to develop the Standard Libraries of Ruby?Hiroshi SHIBATA
I maintain the RubyGems, Bundler and the standard libraries of the Ruby language. So, I've been extract many of the standard libraries to default gems and GitHub at Ruby 3.0. But the some of libraries still remains in only Ruby repository. I will describe these situation.
The document discusses the strategy for building and testing the programming language Hiroshi. It covers:
1. The Ruby Core team which maintains the language and includes over 80 volunteers.
2. The testing strategy for Ruby which involves testing at different levels from the interpreter to libraries. Extensive tests are run on Linux, Windows and macOS.
3. The CI environments used for Ruby development including GitHub Actions, Travis CI and AppVeyor, as well as internal VM clusters. Test results are collected on Ruby CI and discussed on Slack.
Dependency Resolution with Standard LibrariesHiroshi SHIBATA
The document discusses the roadmap for RubyGems and Bundler integration with Ruby 3.0. Key points include:
1) RubyGems 3.1 and Bundler 2.1 were recently released with improvements like lazily loading default gems.
2) Future versions will continue merging the projects, with RubyGems 3.2/Bundler 2.2 integrating into Ruby 2.8.
3) Ruby 3.0 will focus on "gemifying" standard libraries by extracting them to default gems, though some may be excluded.
4) This will require addressing issues around dependency and version resolution for the new default gems.
The document discusses the roadmap for integrating RubyGems and Bundler, including gemifying standard Ruby libraries for Ruby 3. Key points include:
1) RubyGems and Bundler repositories and teams have been merged into a monorepo to more closely integrate the projects.
2) The roadmap includes releasing RubyGems and Bundler versions simultaneously and potentially bumping to RubyGems 4.0 synchronized with Ruby 3.
3) Standard libraries will be extracted to default gems for Ruby 3, aiming to publish all to default gems except those using internal APIs.
4) Issues around dependency resolution and versioning of default gems need to be addressed in the integration.
The Future of library dependency management of RubyHiroshi SHIBATA
The document discusses the integration of package management in Ruby. It provides an overview of RubyGems and Bundler, the two main tools for managing library dependencies in Ruby. It also outlines the roadmap for further integrating RubyGems and Bundler, including merging RubyGems 3.2 into Ruby 2.8 and moving Bundler's canonical repository to RubyGems.org. Additionally, it discusses challenges around dependency resolution compatibility and activation of default gems between different versions of RubyGems and Bundler.
1. The document discusses security topics related to Ruby including defining vulnerabilities, triage policies, and the RubyGems.org workflow.
2. It describes how vulnerabilities are reported and coordinated between developers, and outlines the process of code fixes, releases, and disclosure.
3. Recent attacks on RubyGems.org are reviewed, highlighting account hijacking and typo squatting issues. Solutions discussed include not reusing passwords, using strong unique passwords, and enabling two-factor authentication.
Hiroshi SHIBATA presented on OSS security at the builderscon 2019 conference. The presentation covered:
1. How Ruby handles releases on a regular schedule and processes for stable and development versions.
2. Policies for triaging vulnerabilities based on impact and developing workflow for coordinated security releases.
3. Recent attacks targeting RubyGems where malicious gems were uploaded by hijacking developer accounts or registering typosquatted gems.
4. Steps users can take to improve security like using strong unique passwords, enabling two-factor authentication, and being wary of code injections in gem installations or native extensions.
The Future of library dependency manageement of RubyHiroshi SHIBATA
The document discusses the integration of package ecosystems in Ruby. It covers RubyGems and Bundler, which are used to manage library dependencies in Ruby projects. The document outlines challenges with bundler integration and the roadmap for improvements in RubyGems 4.0, Bundler 2.1, and features coming in Ruby 3.0 like pattern matching and gamification of standard libraries.
The document discusses integrating the Bundler dependency manager into the Ruby programming language core. It covers the benefits of integrating Bundler, such as allowing developers to manage library dependencies directly within Ruby projects. It also discusses challenges faced in integrating Bundler, like ensuring Bundler test suites work properly within the Ruby core codebase. The author details steps taken to start merging Bundler code into Ruby, including adding a "make test-bundler" command to run Bundler tests during development.
1. The first step of package management integration discusses integrating Bundler into RubyGems to provide bundled gems as the default package management solution.
2. What's happened in Ruby 2.6 discusses updates to RubyGems 3 and Bundler 2 that dropped support for older Ruby versions and integrated Bundler fully into Ruby 2.6 as the default package manager.
3. BugMash after releasing Ruby 2.6 summarizes issues that came up after Ruby 2.6's release regarding path injection problems with LOAD_PATH, invalid gemspec generation by the installer, and Bundler version switching on Heroku.
RubyGems is the package manager for Ruby libraries. Hiroshi Shibata discussed recent changes to RubyGems 3 and 4, as well as integration efforts between RubyGems and Bundler. Key points included making the conservative option default in RubyGems 4, installing gems to the user directory by default, and resolving incompatibilities between dependency resolvers in RubyGems and Bundler. The team is working to merge code bases and integrate command line interfaces.
Hiroshi Shibata gave a presentation on Ruby, RubyGems, and Bundler. He discussed his work on the Ruby core team maintaining Ruby versions like 2.6. He then covered updates to RubyGems including version 3 and the upcoming version 4. Finally, he talked about Bundler 2 and efforts to better integrate RubyGems and Bundler.
1. The document discusses RubyGems, Bundler, and rbenv/ruby-build. It provides an overview of each tool's purpose and history.
2. RubyGems is the package manager for Ruby libraries. Bundler is a tool for managing dependencies of Ruby applications. Rbenv/ruby-build allow managing multiple Ruby versions and building Ruby.
3. The document outlines plans to further integrate RubyGems and Bundler, but notes Bundler 2 has not yet been released, which is needed for full integration. Security improvements have also been made to RubyGems.
