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 == Transition of the minizip to minizip-ng as it brings much more optimization and also this change is strongly tied to the [https://fedoraproject.org/wiki/Changes/ZlibNGTransition Zlib Transition Change] as by removing zlib package it will also remove minizip-compat subpackage. == Owner == * Name: [[User:ljavorsk| Lukas Javorsky]] * Email: ljavo...@redhat.com == Detailed Description == As zlib is about to be migrated to zlib-ng, the minizip-compat subpackage will be removed as well. Thus we need to rebuild all of the packages that depend on the minizip-compat with minizip-ng-compat. Also with this, we can add the minizip-ng (without compat) to the Fedora repository as some packages might want to migrate to the more feature-rich implementation of minizip. This change is strongly related to the [https://fedoraproject.org/wiki/Changes/ZlibNGTransition Zlib Transition Change]. == Feedback == Packages that require `minizip-ng` (the current compat version) have been rebuilt with the correct `minizip-ng-compat` package with its new API of version 4 in this [https://copr.fedorainfracloud.org/coprs/ljavorsk/minizip-ng/packages/ COPR repository]. Packages that depend on the `minizip-compat` (subpackage of zlib package) will need to be rebuilt as well. There have been some attempts and only two of them are not building due to this change. Chromium; reported in [https://bugzilla.redhat.com/show_bug.cgi?id=2242271 this Bugzilla]. Libdigidocpp; reported in [https://bugzilla.redhat.com/show_bug.cgi?id=2240599 this Bugzilla]. Everything else is described in the [https://bugzilla.redhat.com/show_bug.cgi?id=2235710 minizip-ng rebase Bugzilla]. Early feedback from community in the [https://lists.fedoraproject.org/archives/list/de...@lists.fedoraproject.org/thread/AJFWDXMTJ5WOMCYO3R6UF6PZAZ6DRMXR/ fedora-devel email thread] == Benefit to Fedora == * minizip-ng has the following features ** Zlib, BZIP2, LZMA, XZ, and ZSTD compression methods. ** Password protection through Traditional PKWARE and WinZIP AES encryption. ** Buffered streaming for improved I/O performance. ** NTFS timestamp support for UTC last modified, last accessed, and creation dates. ** Disk split support for splitting zip archives into multiple files. ** Preservation of file attributes across file systems. ** Follow and store symbolic links. ** Unicode filename support through UTF-8 encoding. ** Legacy character encoding support CP437, CP932, CP936, CP950. ** Streaming interface for easy implementation of additional platforms. == Scope == * Proposal owners: ** Minizip-ng will be rebuilt with minizip-compatible API, obsoleting minizip-compat-1.3 *** Minizip-ng compat mode will be distributed in a new package called minizip-ng-compat, with its respective minizip-ng-compat-devel. *** Initially, minizip-ng-compat will provide minizip-compat = 1.2.13 and minizip-ng-compat-devel will provide minizip-compat-devel = 1.2.13. *** These versions will be updated following the support added to minizip-ng upstream. ** As minizip-ng also bumped the soname, the packages critical to this change will need to be rebuilt in the side-tag. Packages that depend on the minizip-compat will be rebuilt with the new Requires/Buildrequires to minizip-ng-compat (doesn't have to be rebuilt in side-tag). *** This may help to catch ABI-compatibility issues soon. * Other developers: Help with build failures may be requested. All of the packages that fails to build with this change have been reported in Bugzilla * Release engineering: No action required * Policies and guidelines: N/A * Trademark approval: N/A * Alignment with Objectives: N/A == Upgrade/compatibility impact == Minizip-ng has a minizip-compat mode that aims to preserve both API and ABI compatibility with the original Minizip. This is only applicable on the packages that currently require the `minizip-compat` package. Packages that require the `minizip-ng-devel` shared library will be changed to require the new name `minizip-ng-devel-compat` and also will be rebuilt in side-tag. Packages that only require the `minizip-ng` without it's shared library will be changed to `minizip-ng-compat`, so they don't end up with non-compat version of minizip-ng. Minizip-ng-compat doesn't provide the full compatible version of ioapi.h file. Function unzGetCurrentFileZStreamPos64 is not present in this header file as discussed in the [https://github.com/zlib-ng/minizip-ng/issues/447#issuecomment-1773022947 upstream issue]. Currently there are 3 packages that fails to build with new minizip-ng-compat: * Chromium: [https://bugzilla.redhat.com/show_bug.cgi?id=2242271 reported Bugzilla]; possible remediation - use bundled minizip library * Libdigidocpp: [https://bugzilla.redhat.com/show_bug.cgi?id=2240599 reported Bugzilla]; possible remediation - use bundled minizip library * OpenColorIO: [https://bugzilla.redhat.com/show_bug.cgi?id=2239262 reported Bugzilla]; possible remediation - don't upgrade minizip-ng package to the new 4th version of API (stay with minizip-ng-3.10.0). Not preferred as we want to have the latest and greatest versions in Fedora. == How To Test == Update the packages and verify they build without any issues. == User Experience == This change will increase compression efficiency and performance. == Dependencies == List of the packages from Fedora 40 === Requires (minizip-compat) === repoquery -q --repo=rawhide{,-source} --whatrequires 'minizip-compat*' | grep -v 'src$' | pkgname chromedriver chromium chromium-common chromium-headless domoticz hashcat libdigidocpp minizip-compat-devel springlobby === BuildRequires (minizip-compat) === repoquery -q --repo=rawhide{,-source} --whatrequires 'minizip-compat*' | grep 'src$' | pkgname chromium domoticz hashcat libdigidocpp springlobby === Requires (minizip-ng (currently built with compat flags)) === repoquery -q --repo=rawhide{,-source} --whatrequires 'minizip-ng*' | grep -v 'src$' | pkgname collada-dom dolphin-emu dolphin-emu-tool freexl keepassxc libnuml librasterlite2 libsbml libspatialite libxlsxwriter minizip-ng-devel OpenColorIO OpenColorIO-tools perl-LibSBML python3-libsbml qmc2 qmc2-arcade R-libSBML ruby-SBML sigil vxl widelands xiphos zfstream zfstream-devel === BuildRequires (minizip-ng (currently built with compat flags)) === repoquery -q --repo=rawhide{,-source} --whatrequires 'minizip-ng*' | grep 'src$' | pkgname collada-dom COPASI dolphin-emu freexl keepassxc libCombine libnuml librasterlite2 libsbml libsedml libspatialite libxlsxwriter OpenColorIO qmc2 sigil spatialite-gui spatialite-tools vxl widelands wordgrinder xiphos zfstream == Contingency Plan == * Contingency mechanism: Revert the change to Minizip and rebuild dependent packages. However, if we want to revert to minizip-compat, the [https://fedoraproject.org/wiki/Changes/ZlibNGTransition Zlib Transition Change] needs to be reverted as well (minizip-compat is subpackage of zlib package). * Contingency deadline: Beta freeze * Blocks release?
