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.

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

• bigdecimal (Stub out extension build on JRuby ruby/bigdecimal#250)
• cgi (jruby support ruby/cgi#9)
• digest - we have our own impl (java version ruby/digest#20, jruby support ruby/digest#21)
• date
• dbm/gdbm (low priority, rarely used)
• etc (could possibly move to pure-FFI)
• fcntl (same)
• fiddle (not based on FFI)
• io-nonblock (Add TruffleRuby & JRuby in CI and use the correct fallback pattern for rb_io_descriptor() ruby/io-nonblock#12)
• io-wait (JRuby support ruby/io-wait#2)
• nkf (low priority)
• openssl (Stub gemspec for JRuby ruby/openssl#598)
• pathname
• readline-ext
• stringio (Import JRuby's stringio impl ruby/stringio#21)
• strscan (Import JRuby's strscan ruby/strscan#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 ruby/strscan#25.

[headius]

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

[headius]

stringio started in ruby/stringio#21

@headius Thanks for your work! Did we get the approval for relicensing JRuby libraries that are this work at ruby/digest#21 (comment) ?

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]

ruby/digest#21 (comment)

[headius]

@chrisseaton Thank you!

@hsbt That's everyone!

[headius]

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