From f54318853b7d0b2d58809841c05768bc42e1f5b7 Mon Sep 17 00:00:00 2001 From: "masaru.terada" Date: Tue, 7 Nov 2023 08:54:15 +0900 Subject: [PATCH 01/14] Make it loose coupling between RubyGems and RDoc MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit \### Problems There are following problems because of tight coupling between RubyGems and RDoc. 1. If there are braking changes in RDoc, RubyGems is also broken. 2. When we maintain RDoc, we have to change RubyGems. The reason why they are happened is that RubyGems creates documents about a gem with installing it. Note that RubyGems uses functions of RDoc to create documents. Specifically, - Creating documents is executed by `rubygems/lib/rubygems/rdoc.rb`. - `::RDoc::RubygemsHook` which is defined by RDoc is called by the file. \### Solution RubyGems has the plugin system. If a gem includes `rubygems_plugin.rb`, RubyGems loads it. RubyGems executes a process defined in it while installing gems, uninstalling gems or other events. We can use the system to solve the problems. The root cause is RubyGems directly references the class of RDoc. We can remove the root cause by making RDoc RubyGems plugin. Alternatively `rubygems_plugin.rb` creates documents about gems. \### FAQ Q1. Do we need to change codes of RubyGems? A. No, we don't. This change keeps compatibility of API used from RubyGems. Q2. Is it better to delete existing codes related to RDoc in RubyGems? No, it isn't. If we change codes of RubyGems, we can't keep a compatibility. Example: If we delete codes that uses `RDoc::RubygemsHook` in `rubygems/lib/rubygems/rdoc.rb`, documentations are not created with old RDoc. Q3. When can we delete `rubygems/lib/rubygems/rdoc.rb`? A. We can delete it when all users use RDoc including `rubygems_plugin`. Next ruby version is 3.4. If it includes the RDoc including `rubygems_plugin`, we can delete `rubygems/lib/rubygems/rdoc.rb` after ruby 3.3 is EOL. Q4. Is it a breaking change that Rubygems creates documents with rubygems_plugin not RDoc::RubygemsHook? A. No, it isn't. If we simply implement this approach, we move the implementation from `rdoc/lib/rdoc/rubygems_hook.rb` to `rubygems_plugin.rb`. This way can be breaking change. It seems to be fine that we just need to delete `rdoc/rubygems_hook.rb` but it doesn't work. It generates multiple documents. `rubygems/lib/rubygems/rdoc.rb` has the following code. ``` begin require "rdoc/rubygems_hook" # ... rescue LoadError end ``` This code ignores RDoc related processes when `rdoc/rubygems_hook` can't be required. But, this 'require' is not failed. This is because Ruby installs Rdoc as a default gem. So, Rdoc installed as a default gem generates documents and one installed as a normal gem does it too. If you think that this behavior is accectable, we can just delete `rdoc/rubygems_hook.rb`. What do you think about this approach? In this change, we take another approach to solve the problem that creates multiple documents. If `Gem.done_installing(&Gem::RDoc.method(:generation_hook))` in `rubygems/rdoc.rb` doesn't create documents, we can solve the problem. We have some options. * We change `rubygems/rdoc.rb` and then don't execute `Gem.done_installing`. (This is a change for RubyGems.) * We change `rdoc/rubygems_hook.rb` and then make `generation_hook` a no-op method. (This is a change for RDoc.) We choose the latter to avoid changing for RubyGems. \### Test \#### Preparation Install Rdoc which including our changes by executing `rake install`. ❯ rake install We confirmed that Rdoc which including our changes was installed. ❯ gem list | grep rdoc rdoc (6.6.0, default: 6.4.0) \#### Check point We tested to check compatibility. How to chack the compatibility? We tested creating same documents by our RDoc and old RDoc with latest RubyGems. We used following versions to test. ``` ❯ ruby -v ruby 3.1.0p0 (2021-12-25 revision fb4df44d16) [arm64-darwin22] ❯ gem list | grep rdoc rdoc (default: 6.4.0) ❯ ruby -I rubygems/lib rubygems/exe/gem --version 3.5.14 ``` Here is a result of test with old RDoc. We can see that the document is created correctlly with `Parsing...` and `Done installing...`. ``` ❯ ruby -I rubygems/lib rubygems/exe/gem install pkg-config Successfully installed pkg-config-1.5.6 Parsing documentation for pkg-config-1.5.6 Done installing documentation for pkg-config after 0 seconds 1 gem installed ``` Here is a result of test with our RDoc. We can see that the document is created correctlly with `Parsing...` and `Done installing...`. ``` ❯ ruby -I rubygems/lib rubygems/exe/gem install pkg-config Successfully installed pkg-config-1.5.6 Parsing documentation for pkg-config-1.5.6 Done installing documentation for pkg-config after 0 seconds 1 gem installed ``` As you can see we got the same results, our RDoc keeps compatibility. --- lib/rdoc/rubygems_hook.rb | 255 ++---------------------- lib/rubygems_plugin.rb | 277 +++++++++++++++++++++++++++ test/rdoc/test_rdoc_rubygems_hook.rb | 10 +- 3 files changed, 294 insertions(+), 248 deletions(-) create mode 100644 lib/rubygems_plugin.rb diff --git a/lib/rdoc/rubygems_hook.rb b/lib/rdoc/rubygems_hook.rb index 3160072e53..76ec328620 100644 --- a/lib/rdoc/rubygems_hook.rb +++ b/lib/rdoc/rubygems_hook.rb @@ -1,248 +1,17 @@ -# frozen_string_literal: true -require 'rubygems/user_interaction' -require 'fileutils' -require_relative '../rdoc' - -## -# Gem::RDoc provides methods to generate RDoc and ri data for installed gems -# upon gem installation. # -# This file is automatically required by RubyGems 1.9 and newer. - -class RDoc::RubygemsHook - - include Gem::UserInteraction - extend Gem::UserInteraction - - @rdoc_version = nil - @specs = [] - - ## - # Force installation of documentation? - - attr_accessor :force - - ## - # Generate rdoc? - - attr_accessor :generate_rdoc - - ## - # Generate ri data? - - attr_accessor :generate_ri - - class << self - - ## - # Loaded version of RDoc.
