[ruby-core:114184] [Ruby master Feature#19351] Promote bundled gems at Ruby 3.3

Issue #19351 has been updated by deivid (David Rodr=EDguez).





I guess we can try to predict via codesearch which libraries will be affect=
ed by this and fix them in advance?

Feature #19351: Promote bundled gems at Ruby 3.3

----------------------------------------

In Ruby 3.2, the default gems and bundled gems are changed only adding `syn=
tax_suggest`. I and some committers are considering promote default gems to=
 bundled gems again for Ruby 3.3+.



We hope to keep the current developer experience with dependency resolution=
 and ignore the additional work like "Put gem "xxx" into your Gemfile" for =
developers.



### Proposal for Ruby 3.3.0-preview2



I propose the following libraries will promote default gems to bundled gems=
 at Ruby 3.3.0-preview2



```

abbrev

getoptlong

observable

resolv-replace

rinda

nkf (C-ext)

syslog (C-ext)

base64

drb

mutex_m

csv

```



Other default gems depends on `make test-all` or other standard libraries. =
It's hard to promote in this time. And I submit a PoC of bypass feature for=
 Bundler and bundled gems: https://github.com/rubygems/rubygems/pull/6811



This feature add `load_paths` defined by `Gem.bundled_gems` that is pair li=
st of Gem name and version under the Bundler environment. This mean user ca=
n `require` bundled gems like `csv` without `gem "csv"` on Gemfile.



And we need to warn like "'csv' is loaded without Gemfile, add "gem 'csv'" =
in your Gemfile" in `require` or other place. I have no idea how notice thi=
s yet.

### Proposal



I propose the following libraries will promote default gems to bundled gems=
 at Ruby 3.3. They are not the dependencies of Rails and RubyGems/Bundler.



```

abbrev

getoptlong

observable

resolv-replace

rinda

nkf (C-ext)

syslog (C-ext)

```



Update: I removed `optparse` and `un` from above list. Because they are use=
d by Ruby build process.



```

optparse

un

```



Update 2: I also removed the following libraries. `resolv` and `fcntl` are =
used by test of Ruby internal like `test_io.rb`. And we don't have built pr=
ocess of C extension at Windows platform. I gave up to extract `win32ole` i=
n this time.



```

resolv

fcntl (C-ext)

win32ole (C-ext)

```



### Additional works



I also propose to promote rails dependencies without rubygems/bundler deps:



```

base64

drb

mutex_m

```



Update: `delegate` is used by `tempfile`. We need to keep `delegate` as def=
ault gems for build process. and I added `reline` into above list.



Update 2: The following libraries used by tests of `ruby/ruby` and other li=
braries like psych. I need to remove their dependency from `ruby/ruby`.



```

benchmark

forwardable

ipaddr

irb

reline

ostruct

rdoc

singleton

tsort

weakref

bigdecimal (C-ext)

date(datetime) (C-ext)

```



And gems maintained by @kou=20



```

csv

```



Following gems also maintained by @kou, but they are used on RubyGems/Bundl=
er or MJIT. Maybe, We couldn't promote them because RubyGems/Bundler couldn=
't bundle C-ext gems.



```

fiddle (C-ext): used by MJIT

stringio (C-ext) used by RubyGems/Bundler

strscan (C-ext) used by RubyGems/Bundler

```



### Follow-up feature



But if we promote them to bundled gems, many of users need to add like `gem=
 "csv"` into their Gemfile. I'm considering avoiding this situation.



Can we introduce the specific feature of bundled gems to RubyGems or Bundle=
r? Example, bundler have allowed list for bundled gems. So, listed gems cou=
ld be require without Gemfile under the bundle exec.
