https://fedoraproject.org/wiki/Changes/JdkInTreeLibsAndStdclibStatic This document represents a proposed Change. As part of the Changes process, proposals are publicly announced in order to receive community feedback. This proposal will only be implemented if approved by the Fedora Engineering Steering Committee. == Summary == This is initial step to move JDKs to be more like other JDKs, to build proper transferable images, and to lower certification burden of each binary. Long storyshort, first step in: https://fedoraproject.org/wiki/MoveFedoraJDKsToBecomePortableJDKs This first step will move, one by one, individual JDKs in F37 to be built `--with-stdc++lib=static` and against in-tree (bundeld) libraries: `--with-zlib="bundled" --with-freetype="bundled" --with-libjpeg="bundled" --with-giflib="bundled" --withlibpng="bundled" --with-lcms="bundled" --with-harfbuzz="bundled" ` We already made a heavy testing of the behavior, and user should not face negative experience. I'm not sure if this is == Owner == * Name: [[User:jvanek| Jiri Vanek]] * Email: jvanek@xxxxxxxxxx == Detailed Description == Please see https://fedoraproject.org/wiki/MoveFedoraJDKsToBecomePortableJDKs for whole picture Please see https://fedoraproject.org/wiki/MoveFedoraJDKsToBecomePortableJDKs#Move_JDKs_in_RPMs_to_become_portable for this particular step. I would rather keep the details in the main page then here. == Feedback == According to short investigations, there are already precedents, where certification is a reason to build once, certificate, and repack. According to developers, the non-portbale JDK is causing upredicted behavior different from other JDK vendors According to JDK packagers and testers, there is to much JDKs now, and the https://fedoraproject.org/wiki/MoveFedoraJDKsToBecomePortableJDKs#Move_Fedora_JDKs_to_become_single-built.2C_portable.2C_ordinary_JDKs.2C_while_keeping_comfortable.2C_usual_system_integration is the only way out == Benefit to Fedora == Please see https://fedoraproject.org/wiki/MoveFedoraJDKsToBecomePortableJDKs#Motivation for whole picture. This particular proposal's main benefit will be that Fedora's JDKs as packed in RPMs will again start to resemble upstream JDKs and other vendors build, and some platform specific issues disappear, while JDKs remain same in view of system integration and user experience == Scope == * Proposal owners: push improved version of https://src.fedoraproject.org/rpms/java-latest-openjdk/pull-request/98#request_diff to all JDKs - one by one from latest, over 17 to 11 and 8. Once settled down in F37 the backport to F36 is expected. * Other developers: really, nothing. If there will be unexpected impact to other developers, the https://fedoraproject.org/wiki/MoveFedoraJDKsToBecomePortableJDKs may need rework * Release engineering: N/A [https://pagure.io/releng/issues #Releng issue number] * Policies and guidelines: N/A (not needed for this Change) * Trademark approval: N/A (not needed for this Change) * Alignment with Objectives: == Upgrade/compatibility impact == The compatibility and upgrade path should remain completely smooth. == How To Test == Install system JDK (java-17-openjdk) and ru your favorite application or development. No regression should be noted. == User Experience == Because of in-tree libraries, minimal image or font rendering differences canbe spotted after very detailed investigations - https://fedoraproject.org/wiki/MoveFedoraJDKsToBecomePortableJDKs#Side_effects - still, no of th e https://fedoraproject.org/wiki/MoveFedoraJDKsToBecomePortableJDKs#Known_issues should be hit by this proposal. == Dependencies == No dependent packages should notice the change. == Contingency Plan == * Contingency mechanism: Revert the patches and rework https://fedoraproject.org/wiki/MoveFedoraJDKsToBecomePortableJDKs * Contingency deadline: before f37 release * Blocks release? Unless the java-stack will become completely borked then no. == Documentation == https://fedoraproject.org/wiki/MoveFedoraJDKsToBecomePortableJDKs -- Ben Cotton He / Him / His Fedora Program Manager Red Hat TZ=America/Indiana/Indianapolis _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
