Libraries that need to be gemified

[headius]

Updated: Many gems have been incorporated (on our 3.0 branch) and some are in progress, so I am updating this description to include a complete list of the remaining gems needed to match Ruby 3 (in JRuby 9.4). See #4875 for earlier discussion about gemification.

Default Gems, pure-ruby

Most of the pure-Ruby libraries have been updated to use the gems. The exceptions below may not install or may have other native library dependencies that do not yet support JRuby.

• [x] english: refused to install through mavengems for some reason
• [ ] debug: out of sync in CRuby repo and missing JRuby tweaks
• [x] net/ftp: tweaks for missing jruby-openssl functionality
• [x] net/http: tweaks for JDK proxy properties
• [x] net/protocol: depends on C extension gems that do not currently have JRuby support
• [x] open3: we have custom logic that needs to be merged with the gem (https://github.com/ruby/open3/pull/3)
• [ ] readline: need to get JRuby support into readline-ext before we can remove our version
• [ ] resolv: needs some JRuby tweaks in the gem
• [x] securerandom: we have a custom version that uses a native extension
• [ ] set: ours is all native and needs to be merged with the gem
• [x] tempfile: switching to the gem in JRuby 10 (#7973)
• [ ] tmpdir: minor tweaks to our version that needed to be merged
• [x] weakref: ours is all native and needs to be merged with the gem

Default gems, native extensions

All of these gems need native JRuby support, or some workaround:

• [x] bigdecimal (https://github.com/ruby/bigdecimal/pull/250)
• [x] cgi (https://github.com/ruby/cgi/pull/9)
• [x] digest - we have our own impl (ruby/digest#20, ruby/digest#21)
• [ ] date
• [ ] dbm/gdbm (low priority, rarely used)
• [ ] etc (could possibly move to pure-FFI)
• [ ] fcntl (same)
• [ ] fiddle (not based on FFI)
• [x] io-nonblock (https://github.com/ruby/io-nonblock/pull/12)
• [x] io-wait (https://github.com/ruby/io-wait/pull/2)
• [ ] nkf (low priority)
• [ ] openssl (https://github.com/ruby/openssl/pull/598)
• [ ] pathname
• [ ] readline-ext
• [x] stringio (https://github.com/ruby/stringio/pull/21)
• [x] strscan (https://github.com/ruby/strscan/pull/25)
• [ ] syslog
• [ ] win32ole
• [ ] zlib

Bundled gems, not default but with native requirements

• [ ] rbs: includes a large native extension for CRuby that we do not have
• [ ] typeprof: depends on rbs

👍 I'll support this.

strscan gemification is started in https://github.com/ruby/strscan/pull/25.

[headius]

See ruby/digest#20 / ruby/digest#21 for the gemification of Digest.

[headius]

stringio started in https://github.com/ruby/stringio/pull/21

@headius Thanks for your work! Did we get the approval for relicensing JRuby libraries that are this work at https://github.com/ruby/digest/pull/21#issuecomment-861015401 ?

I'm not sure what we should get the approval for that each pull requests.

[headius]

@hsbt I believe we got approval from everyone except @chrisseaton in that PR and updated my comment to be a checklist.

@chrisseaton You responded affirmatively to the PR, but could you add something along the lines of "I consent to having my contributions relicensed etc etc"?

[headius]

@hsbt FWIW having talked with legal-ish folks about license changes, as long as everyone publicly states that they are ok with it that is generally enough, legally-speaking.

[chrisseaton]

[headius]

@chrisseaton Thank you!

@hsbt That's everyone!

[headius]

I will try to make sure the other PRs can get relicensed as well.

[headius]

I have updated the description with a complete list of Ruby 3.0 gemified libraries and links to current issues and PRs.

[headius]

complete list

At least a complete list of the gemified libraries that we could not trivially incorporate. Several like fileutils and rdoc already worked fine and have just been switched to default gems.

[headius]

The io-wait, stringio, and strscan gems now support JRuby since the last time I updated this.

[headius]

The english, net-ftp, net-http, net-protocol, securerandom, and weakref libraries are also now sourced from gems.

[headius]

bigdecimal and openssl have merged JRuby gem configs for stub gems that depend on our own libraries:

• https://github.com/ruby/bigdecimal/pull/250
• https://github.com/ruby/openssl/pull/598

These have not yet been released in gems.

I add JRuby in the io-nonblock CI in https://github.com/ruby/io-nonblock/pull/12
