[opensuse-packaging] New macro to limit resources allocation per thread

by Tomas Chvatal

Hello all, For use in libreoffice, chromium and others I've created macro that should allow you to limit jobs based on some constraints you can set later on in the spec to avoid OOM crashes. The usage is pretty straight forward (Once it is accepted in Tumbleweed): === BuildRequires: memory-constraints %build # require 2GB mem per thread %limit_build -m 2000 make %{?_smp_mflags} ==== Here the _smp_mflags vaule for 8GB machine would be 4 while default is number of cores (lets say 16)... Both macros %jobs and %_smp_mflags are overriden as such the integration should be really painless if you need to do something like this. Tom

[opensuse-packaging] SLE_15 vs SLE_15_backports

by Peter Czanik

Hi, Trying to compile syslog-ng in my repo both for SLE_15 and SLE_15_backports and ran into something interesting. I use the following to detect SLES, and it works fine for the SLE_15 variant. But for SLE_15_backports I get "nothing provides riemann-c-client-devel" # riemann does not compile on SLES %if !0%{?is_opensuse} %bcond_with riemann %else %bcond_without riemann %endif Any clues why the above does not work for backports?

I tried to connect to the Asset Library from within a patched Godot after deleting the bundled certificates during build, once with a build where "system certificates" was enabled (a) and once disabled (b). The system was configured to only trust the "DST Root CA X3" root CA for the "Let's Encrypt" intermediate CA.

In my opinion a major reason for openSUSE preferring to have this option is, that this will reflect the configuration of a user's system dynamically and isn't limited to the default trust settings of neither Mozilla nor the (openSUSE) Distribution. >> Whether this will survive the switch to mbedtls and if this is something >> upstream might be interested in, I'm not sure but future will tell. > > Should be quite similar for mbedTLS.

I might look into this because we would have to do it for version 3.1 anyhow but don't want to promise anything right now.

[opensuse-packaging] Packaging Godot

by cunix

Rémi Verschelde: [...] > I don't think there's much left that can be unbundled in a realistic way. > As mentioned, I'm both the upstream maintainer and a RPM packager, and I'm > very familiar with unbundling policies. While Max and me continue trying to package Godot in a form acceptable for Factory, a few other questions arose, i hope Godot experts and Factory policy interpreters can help us with. Please correct me if my assumption is false, that Godot currently isn't able to consider certificates at run time with trust settings determined from the users machine to verify server certificates used for transport encryption. Instead, Godot uses a static list of trusted certificates, hardwired during build. This list is bundled in the Godot source code. While there is no explicit option to unbundle these trusted roots, we were able to replace the Godot "bundle" with an openSUSE "bundle" [1], derived from the "ca-certificates-mozilla" package. This way i expect the Godot package to get rebuild automatically on obs, if "ca-certificates-mozilla" gets some sort of update. Questions are: 1. Is such a "replacement" enough and acceptable for Tumbleweed inclusion, or is it undesired and a reason to "decline"? 2. Is this "unbundling" or should we still include a "Provides bundled(ca-certificates-mozilla)" in the spec file? 3. Is it perhaps unacceptable from a security point of view to have a package in the openSUSE distribution, that doesn't use the users system trust settings but is configured to always rely on the openSUSE defaults? (Firefox does something similar but offers a UI to change them). 4. Should we take the same approach for some other parts of Godot? For example it might be possible to replace the bundled fonts with their openSUSE counterparts. This will be static as well and not using installed fonts dynamically as far as the fonts in /thirdparty/fonts are concerned.

[opensuse-packaging] No Leap repos anymore in devel:languages:python?

by Thomas Schraitle

Hi packagers, Stefan observed that in d:l:p no Leap repositories are available anymore. There are Arm, PowerPC, zSystems, and Tumbleweed. Are there any reasons why they completely vanished? Can the Leap repos be readded again? I think, a lot of other repositories depend on it. :) (Please keep Stefan in CC) Thanks! -- Gruß/Regards, Thomas Schraitle ---------------------------------------------------------------------- SUSE LINUX GmbH (o< Maxfeldstrasse 5 /\\ Documentation Specialist 90409 Nuernberg, Germany _\_v http://www.suse.com http://lizards.opensuse.org/author/thomas-schraitle/ GF: Felix Imendörffer, Jane Smithard, Dilip Upmanyu, Graham Norton, HRB 21284 (AG Nürnberg) -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-packaging+owner(a)opensuse.org

[opensuse-packaging] trac requires python-pygments, which cannot be found on oS Leap 15.0

by 686f6c6d

Greetings, when I try to install trac[0] on openSUSE Leap 15.0, I receive the following error: ------------------------------ 8< ------------------------------ # zypper in --dry-run trac Loading repository data... Reading installed packages... Resolving package dependencies... Problem: nothing provides python-pygments needed by trac-1.2.2-lp150.1.2.noarch Solution 1: do not install trac-1.2.2-lp150.1.2.noarch Solution 2: break trac-1.2.2-lp150.1.2.noarch by ignoring some of its dependencies Choose from above solutions by number or cancel [1/2/c] (c): ------------------------------ >8 ------------------------------ This is strange, because python-pygments should be available from the oS 15.0 base repo (as the spec[1] provides the exact spelling trac requires[2]). However, when I use OBS to display the provides of the built RPM, the provides is missing[3]. How come? Is this an OBS issue or am I misunderstanding something? What can I do?

[opensuse-packaging] Manually run repo-checker

by Todd Rme

Is there a way to manually run repo-checker on a package or repository? Specifically, I want to run the check to see if the built packages are installable. I think I fixed such an issue but I want to check it before I submit it. -- To unsubscribe, e-mail: opensuse-packaging+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-packaging+owner(a)opensuse.org

[opensuse-packaging] Repo Checker notifications for i586 kernel modules

by Matthias Bach

Hi, I have a kernel module I maintain in the hardware project. From time to time I get the following comment from the repo checker: > Repo Checker wrote in package hardware/hdjmod: > > The version of this package in openSUSE:Factory has installation issues and may not be installable: > > can't install hdjmod-kmp-default-1.28_k4.17.3_1-24.3.i586: > nothing provides kernel-uname-r = 4.17.3-1-default needed by hdjmod-kmp- default-1.28_k4.17.3_1-24.3.i586 > (we have kernel-default-base-4.17.4-1.4.i586) > (we have kernel-default-4.17.4-1.4.i586) > > can't install hdjmod-kmp-pae-1.28_k4.17.3_1-24.3.i586: > nothing provides kernel-pae needed by hdjmod-kmp- pae-1.28_k4.17.3_1-24.3.i586 > nothing provides kernel-uname-r = 4.17.3-1-pae needed by hdjmod-kmp- pae-1.28_k4.17.3_1-24.3.i586 > (we have kernel-default-base-4.17.4-1.4.i586) > (we have kernel-default-4.17.4-1.4.i586) TBH, it is completely unclear to me weather this is some transient error caused by new kernel builds or an actual problem, and repo checker not being locally runnable doesn't help the problem [1]. The problem does not show for x86_64 and the package is completely based on the standard process for building kernel packages on OBS [2]. Is there anything obvious I might be doing wrong? Any hints on what I could do to lock in the the underlying issue?

[opensuse-packaging] BuildRequires GCC7 for SLES12

by Darin Perusich

Hi All, How do I go about making GCC7 available for SLES12 in OBS? Outside OBS I just add the Toolchain repo, but it doesn't appear to be available.The application I'm trying to package requires c++17, hence the need.
