Drop i686 builds of jdk8,11,17 and latest (18) rpms from f37 onwards

Summary

java-1.8.0-openjdk, java-11-openjdk, java-17-openjdk and java-latest-openjdk packages will no longer build i686 subpackages

Owner

Name: Jiri Vanek
Email: <jvanek@redhat.com>
Product: java and java stack
Responsible WG: java-sig (java and java-maint)(which no longer exists)

Current status

Targeted release: Fedora 37
Last updated: 2022-07-04
devel thread
FESCo issue: #2772
Tracker bug: #2083750
Release notes #835

Expected schedule

during march, drop i686 builds from all jdks in fedora rawhide

Detailed Description

Fedora currently ships:

java-1.8.0-openjdk (LTS)
java-11-openjdk (LTS)
java-17-openjdk (LTS)
java-latest-openjdk (STS, jdk18).

All those builds on all architectures except jdk8, where arm32 with jit is built by different package. Unluckily, the i686 bit builds of jdk are rotten in upstream. The recent breakage of i686 JIT just before branching nearly killed jdk17 as system jdk feature. The rotting have main visibility with newer GCCs. If GCC bump, and it does, it always triggers new issues in i686 JIT, and there is less and less people to somehow workaround them. Unluckily, there is probably no longer anyone willing to really fix them

Although there is https://fedoraproject.org/wiki/Changes/EncourageI686LeafRemoval , this proposal have nothign to do with it, not even inspiration. People about OpenJDK learned about after this jdk one was announced.

Benefit to Fedora

The i686 builds are rotten in usptream, and to patch them localy had become pain. We may be introducing very bugy i686 jdk. Better then to do so, we would rather not ship that at all. This will untie hands of both JDK and GCC developers, who will no longer need to dive into nasty legacy code.

Scope

Change owners

After recursive dependency scan was done, i was discovered that the change affects moreover whole system
- initial recursive scan pkg requiring or build requiring java and friends (https://github.com/judovana/FedoraSystemJdkBump/blob/1f126a2d7a4235593b1575467f420b185e5ecb13/scritps/listPkgs/recursiveGlue.sh#L54) pulled in automake and few others, which n second recursive round pulled in moreover whole system
  - I do no have record of this search as it was useless
- Second run was run without automake. Still second round took in automake and thus third and fourth recursion run into morevoer whole system.
  - those results are already parse able. I even generated the chart, but that was pretty flat pointng to automake and autoconf
  - Reuslts: https://jvanek.fedorapeople.org/i686Deps/withAutconf.tar.gz
- third run was run again with autoconf and automake, however all build time requires for noarch results were omitted, as those have no real impact in real usage
  - unluckily during recursion, automake and autoconf were hit again on level 3 and four, so later whole system got pulled in
  - results: https://jvanek.fedorapeople.org/i686Deps/withNoarcBrOff.tar.gz
- final sane scan was done with all build time requires for noarch packages ommited, together with big blacklist of already known trouble makers: https://github.com/judovana/FedoraSystemJdkBump/blob/1f126a2d7a4235593b1575467f420b185e5ecb13/scritps/listPkgs/recursiveGlue.sh#L142
- results https://jvanek.fedorapeople.org/i686Deps/withNoarcBrOffWithBlacklist.tar.gz
- those results are already sane (70 000 edges in unreadable chart)

Workflow

new macro %{java_arches} which will be of value : aarch64 ppc64le s390x x86_64
- will be declared
Once done,
- All most crucial affected pkg - the blacklist + few others, eg R,graphviz (suggestions welcomed, bottom of sorted by dependent children list) will get filled bugzilla -listing - eg:

adapt [cairo] to removal of java on i686

Dear maintainer, we are going to drop i686 java-openjdk packages in f37 - https://fedoraproject.org/wiki/Changes/Drop_i686_JDKs
Your package (maybe jsut soem subpakcage) is transitively affected by this change:

[cairo<-libxcb<-doxygen<-git<-subversion<-java-11-openjdk-devel
cairo<-libxcb<-graphviz<-ruby<-git<-subversion<-java-11-openjdk-devel
cairo<-libxcb<-graphviz<-R-devel<-R-java-devel<-java-17-openjdk-devel
...
cairo<-gtk-doc<-docbook-utils<-gawk<-git<-gawk<-git<-subversion<-java-11-openjdk-devel
Shown 50 from 568]

This package was selected as one of the most crucial, which when missing, will burn distro down.
Please take care, and adapt  your package to exclude java on i686. For  your convenience, there was added macro %{java_arches}, including all arches java is available on,  which you can use to ifarch-out java specific features out in i686 (on non-java arches). Although for plain java package, the change is as simple as https://src.fedoraproject.org/rpms/maven/c/520942645bfd1e4721dacd536a6ccbf80495a8ae?branch=rawhide, you can not use it. The ExclusiveArch: %{java_arches} is not going to work for you, because your package is not simple java application, and also non-java world depends on it (even if you are one of dozen noarchs in this set)
See exemplar PR: https://src.fedoraproject.org/rpms/graphviz/pull-request/9#request_diff
See more details eg in:: https://bugzilla.redhat.com/show_bug.cgi?id=2102298
See why in : https://pagure.io/fesco/issue/2772
Please read carefully proposal: https://fedoraproject.org/wiki/Changes/Drop_i686_JDKs
Please see tracking bug for most up to date informations: https://bugzilla.redhat.com/show_bug.cgi?id=2083750

I'm terribly sorry to report this bug so late in f37 lifecycle. If you can, please handle this with priority.

- all native (not noarch) direct dependencies of javas', maven ant (as in here and here (to be generated) will get filled bugzilla -listing - eg:

native [libreoffice] depends on to be removed i686 java-openjdk packages

Dear maintainer, we are going to drop i686 java packages in f37 - https://fedoraproject.org/wiki/Changes/Drop_i686_JDKs
your package (or maybe jsut some subpackage)  is directly depending on java and is native.

Please take care, and adapt  your package to exclude java on i686. For  your convenience, there was added macro %{java_arches}, including all arches java is available on,  which you can use to ifarch-out java specific features out in i686 (on non-java arches). Although for plain java package, the change is as simple as https://src.fedoraproject.org/rpms/maven/c/520942645bfd1e4721dacd536a6ccbf80495a8ae?branch=rawhide, you can not use it. The ExclusiveArch: %{java_arches} is not going to work for you, because your package is not simple java application, and also non-java world depends on it.

- all noarch direct java, amven ant... dependencies will -listing - get auto injected ExclusiveArch: %{java_arches} noarch if not present, or appended by %{java_arches} if ExclusiveArch already there
- all bugs will block this feature main bug
if all goes ok, we will simply stop building i686 java pacakges in rawhide
I'm not sure if there is any sense in creating copr for this, as there is no proper i686 there...

Other developers

may notice the multilib i686 java missing.
it is up to them to drop i686 builds or to povide workaround (if possible)
all the bugreports should contain precisse instructions what to do:

If you are using %{ix86} or i686 ExclusiveArch, in the java depending subpkg, you ahve to drop it.
You should declare  ExclusiveArch: %{java_arches} noarch in your noarch java depending subpkgs
You should declare  ExclusiveArch: %{java_arches} in your archdull java depending pkgs
Note that you really have to ifarch the depndece out, so you do not randomly fail because of BR not satisfied if your builder wil be i686, which can happen.
See examples: 
https://src.fedoraproject.org/rpms/graphviz/pull-request/9
https://src.fedoraproject.org/rpms/maven/c/520942645bfd1e4721dacd536a6ccbf80495a8ae?branch=rawhide
todo automake once https://bugzilla.redhat.com/show_bug.cgi?id=2102298 is done

Other

Release engineering: #10686
- mass rebuild will NOT be required for this change

Trademark approval: N/A (not needed for this Change)
Bug assignees will need to verify the impact of i686

Upgrade/compatibility impact

The upgrade on multilib systems will lead to autoremoval of i686 javastack
which should be minimum if above bugzillas are properly handled

How To Test

install i686 java will result to not packages found

User Experience

User experience on multilib systems will be bad. Bad reasonable.

Dependencies

There are is unknown number of multilib java consumers. I expect some of them may rise voice, but that will have to handled one by one.

Contingency Plan

Contingency mechanism: return i686 java packages
Contingency date: (not provided)

Documentation

Will be needed...

Release Notes

None yet...

final listings

All those packages vere identified as live, valid rpm top level components - non subpackages, not dead.pcakcage.

Automake is handled individually: https://bugzilla.redhat.com/show_bug.cgi?id=2102298 note, that more packages can be added to this basic set, but the number of dependent pkgs was goind down with exponential speed.
