nodejs-electron
by Andreas Schneider 15 Sep '22

15 Sep '22

Hello! Over the past 8 month, I've been working on getting Electron [1] built on Fedora. Yesterday I was finally able to do the first working build for Fedora Rawhide [2]. This was possible because we finally have ffmpeg [3] in Fedora. My use for Electron is that I want to run signal-desktop [4] on Fedora. You can get electron and signal-packages packages for it at [5]. Is there interest to bring nodejs-electron into Fedora and if yes, would someone be interested to maintain it? I don't have the time to maintain it but I'm happy to help as a co-maintainer. Best regards Andreas [1] https://www.electronjs.org/ [2] https://build.opensuse.org/package/show/network:im:signal/nodejs-electron [3] https://src.fedoraproject.org/rpms/ffmpeg/ [4] https://build.opensuse.org/package/show/network:im:signal/signal-desktop [5] https://download.opensuse.org/repositories/network:/im:/signal/ Fedora_Rawhide/x86_64/

Planning to start unifying native and mingw packages
by Sandro Mani 03 Sep '22

03 Sep '22

Hi Following recent discussions and to reduce the maintenance burden, I'm planning to start merging native and mingw packages. Initially, I'll be looking at these packages where I maintain both variants: eigen3 mingw-eigen3 enchant2 mingw-enchant2 freeimage mingw-freeimage gdal mingw-gdal GeographicLib mingw-GeographicLib geos mingw-geos giflib mingw-giflib gtkspell3 mingw-gtkspell3 gtkspellmm30 mingw-gtkspellmm30 jxrlib mingw-jxrlib leptonica mingw-leptonica libgeotiff mingw-libgeotiff libimagequant mingw-libimagequant libkml mingw-libkml librttopo mingw-librttopo libspatialite mingw-libspatialite libwebp mingw-libwebp openjpeg2 mingw-openjpeg2 OpenSceneGraph mingw-OpenSceneGraph osgearth mingw-osgearth podofo mingw-podofo proj mingw-proj python-pillow mingw-python-pillow qtspell mingw-qtspell shapelib mingw-shapelib svg2svgt mingw-svg2svgt tesseract mingw-tesseract uriparser mingw-uriparser I'm performing test builds here [1]. Once I've got them all building there, if there are no objections, I plan to push to F37 and retire all the corresponding mingw repos.

F37 Change: Drop i686 builds of jdk8,11,17 and latest (18) rpms from f37 onwards (System-Wide Change)
by Ben Cotton 13 Jul '22

https://fedoraproject.org/wiki/Changes/Drop_i686_JDKs == 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: [[User:jvanek| Jiri Vanek]] * Email: <jvanek(a)redhat.com> * Product: java and java stack * Responsible WG: java-sig (java and java-maint)(which no longer exists) === 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 == 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 ==== * we will simiply stop building i686 pkg in rawhide ==== Other developers ==== * may notice the multilib i686 java missing. * it is up to them to drop i686 builds or to povide workaround (if possible) ==== Other ==== * Release engineering: https://pagure.io/releng/issue/10686 * Trademark approval: N/A (not needed for this Change) == Upgrade/compatibility impact == * The upgrade on multilib systems will lead to autoremoval of i686 javastack * which should be minimum - 99% of javastack is noarch == 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 packages * Contingency date: (not provided) == Documentation == Will be neded... == Release Notes == None yet... -- Ben Cotton He / Him / His Fedora Program Manager Red Hat TZ=America/Indiana/Indianapolis

Claim delve
by Alejandro Saez Morollon 29 Jun '22

29 Jun '22

Hi there, folks. Delve[0] (a Golang debugger) was retired due to the impossibility of building a new version of delve for dependencies issues. I would like to claim the package and fix the situation. I already have one of the dependencies[1] in the works. I already talked with the original maintainer (he's in cc) and he is OK with it. Thanks.

Wine MinGW system libraries
by Zebediah Figura 11 Jun '22

11 Jun '22

Hello all, I'm a contributor to the Wine project. To summarize the following mail, Wine needs special versions of some of its normal dependencies, such as libfreetype and libgnutls, built using the MinGW cross-compiler, and I'm sending out a mail to major distributions in order to get some feedback from our packagers on how these should be built and packaged. For a long time Wine has built all of its Win32 libraries (DLLs and EXEs) as ELF binaries. For various reasons related to application compatibility, we have started building our binaries as PE instead, using the MinGW cross-compiler. It is our intent to expand this to some of our dependencies as well. The list of dependencies that we intend to build using MinGW is not quite fixed yet, but we expect it to include and be mostly limited to the following: * libvkd3d * libFAudio * libgnutls * zlib (currently included via manual source import) * libmpg123 * libgsm * libpng * libjpeg-turbo * libtiff * libfreetype * liblcms2 * jxrlib and dependencies of the above packages (not including CRT dependencies, which Wine provides). There is currently some internal discussion about how these dependencies should be built and linked. There are essentially three questions I see that need to be resolved, and while these resolutions have a significant impact on the Wine building and development process, they also have an impact on distributions, and accordingly I'd like to get input from our packagers to ensure that their considerations are accurately taken into account. (1) Should we build via source import, or link statically, or dynamically? Static linking and source imports are dispreferred by Fedora [1] [2], as by many distributions, on the grounds that they cause duplication of libraries on disk and in memory, and make it harder to update the libraries in question (see also question 2). They also make building and bisecting harder. Note however that if they are linked dynamically, we need to make sure that we load our packages instead of MinGW builds of open-source libraries with applications ship with. Accordingly we need each library to be renamed, and to link to renamed dependencies. For example, if application X ships with its own copy of libfreetype-6.dll, we need to make sure that our gdi32.dll links to libwinefreetype-6.dll instead, and that libwinefreetype-6.dll links to libwineharfbuzz-0.dll and winezlib.dll. I think, although I haven't completely verified yet, that this can be done just with build scripts (i.e. no source patches), by using e.g. --with-zlib=/path/to/winezlib.dll. Accordingly, although static linking and source imports are generally disprefered, it may quite likely be preferable in our case. We don't get the benefits of on-disk deduplication, since Wine is essentially the only piece of software which needs these libraries. (2) If we use dynamic libraries, should dependencies be included in the main wine package, or packaged separately? This is mostly a question for packagers, although it also relates to (3). I expect that Fedora (and most distributions) want to answer "packaged separately" here, on the grounds that this lets them update (say) Wine's libgnutls separately, and in sync with ELF libgnutls, if some security fix is needed. There is a snag, though: we need libraries to be copied into the prefix (there's some internal effort to allow using something like symlinks instead, but this hard and not done yet). Normally we perform this copy every time Wine is updated, but if Wine and its dependencies aren't updated on the same schedule, we may end up loading an old version of a dependency in the prefix, thus missing the point of the update. (3) If dependencies are packaged separately, should Wine build them as part of its build tree (e.g. using submodules), or find and link (statically or dynamically) to existing binaries? Linking to existing binaries is generally preferable: it avoids duplication on disk; it reduces compile times when compiling a single package from source (especially the first time). However, we aren't going to benefit from on-disk duplication. And, most importantly, unlike with ELF dependencies, there is no standardized way to locate MinGW libraries—especially if it comes to Wine-specific libraries. We would need a way for Wine's configure script to find these packages—and ideally find them automatically, or else fall back to a submodule-based approach. If we rely on distributions to provide our dependencies, the best idea I have here would be something like a x86_64-w64-mingw32-pkg-config. And if we use shared libraries rather than static, things get worse: we need to know the exact path of each library and its dependencies so that we can copy (or symlink) them into a user's WINEPREFIX. For what it's worth, the current proposed solution (which has the support of the Wine maintainer) involves source imports and submodules. There's probably room for changing our approach even after things are committed, but I'd still like to get early feedback from distributions, and make sure that their interests are accurately represented, before we commit. In short, it's not clear whether distributions want their no-static-library policies to apply to us as well, or whether we're enough of a special case and would be enough of a pain to package that they'd rather we deal with the hard parts, and I don't want us to make any assumptions. ἔρρωσθε, Zebediah [1] https://docs.fedoraproject.org/en-US/packaging-guidelines/#packaging-static… [2] https://fedoraproject.org/wiki/Bundled_Libraries

What to do with packages that fail to install since Fedora 34 but BZs are ASSIGNED?
by Miro Hrončok 10 Jun '22

10 Jun '22

Hello, during the Fedora 34 development cycle a year ago, I've reported the following buzgillas about packages that don't install: https://bugzilla.redhat.com/buglist.cgi?bug_status=ASSIGNED&f1=blocked&f2=b… They were set to ASSIGNED by their maintainers but since then, they still don't install on Fedora 34, Fedora 35 or Fedora 36. I see no point in keeping such packages in the repositories, yet the policy does not currently allow to do anything other than keep them. Should I take some steps, or do we keep building and shipping the broken packages forever? -- Miro Hrončok -- Phone: +420777974800 IRC: mhroncok

Minizip pull requests
by Julian Sikorski 10 Jun '22

10 Jun '22

Hello, I have created two PRs against minizip which are yet to be merged: - https://src.fedoraproject.org/rpms/minizip/pull-request/3 - https://src.fedoraproject.org/rpms/minizip/pull-request/4 The first one should be a low risk one and should allow pkg-config using dependencies like (shameless self-interest plug) to build against system minizip again. The second one needs support from a provenpackager. I tried rebuilding the 18 dependencies of minizip and this is a bit tricky for two reasons: - libsmbl and libspatialite need to be rebuilt before the other dependencies - I cannot figure out how to get fedpkg srpm to work with libspatialite, I am getting a Package already exists: %package debuginfo error from the %{?mingw_debug_package} line. I am sure this is something someone familiar with mingw can fix in a shortest amount of time. Other than that, I can confirm that 13 dependencies can be rebuilt with no changes. How can we move this forward? Best regards, Julian

Hardware without AES-NI: use xchacha12/Adiantum instead of AES-XTS
by py0xc3 08 Jun '22

08 Jun '22

Good everning, I just experienced that, when setting up a new Fedora, Anaconda (both "Custom" and "Advanced Custom (Blivet-GUI)") always uses aes-xts-plain64 for disk encryption, even if the hardware does not support AES-NI. Does it make sense to use xchacha12,aes-adiantum-plain64 by default if there is no AES-NI in the hardware? For a general use case, the security advantages of Adiantum can be neglected; both aes-xts & chacha-adiantum are secure. But there are big performance disadvantages of AES when there is no AES-NI (this was the major reason for merging Adiantum into the kernel). Besides the use of system resources, netbooks and such may have strongly decreased battery life times with aes-xts (the issue is primarily aes, not xts). I tested with Fedora 35, KDE spin; but as the issue is Anaconda-centric, I expect that other Workstation installations tend to the same behavior. Adjustments would be limited to Anaconda. Regards & stay safe, Chris
