Proposed Fedora packaging guideline: Forge-hosted projects packaging automation
by nicolas.mailhot＠laposte.net 07 Feb '18

07 Feb '18

Hi, I am proposing for inclusion a macro set aimed at automating the packaging of forge-hosted projects. — Packaging draft: https://fedoraproject.org/wiki/Forge-hosted_projects_packaging_automation — FPC ticket: https://pagure.io/packaging-committee/issue/719 (without the “hasdraft” tag because I don't know how to add it in pagure) — fedora-rpm-macros RFE with the macro file: https://bugzilla.redhat.com/show_bug.cgi?id=1523779 What it does: conversion of a forge url, version, tag, commit set to the values expected in rpm specfiles, in optional rpm variables. Computation of the corresponding %{dist}. Objective: centralize forge structure know-how in a single technical place, deprecate all the complex manual forge URL handling spread over many Fedora spec files, simplify packaging and spend time on more interesting stuff. What's currently implemented: definitions for github.com and code.googlesource.com (I didn't want to propose stuff I didn't use myself. Adding more definitions is trivial. The macros are in Lua which is change-friendly, no arcane rpm syntax knowledge is needed). Please consult packaging draft for full information. This is a spin-off of the work I'm currently doing on Go packaging, as Go is heavily forge-oriented. I took the time to extract the generic non-Go-specific forge knowledge in a separate macro file. The macros have been heavily tested on real-life Go projects with quite a lot of variance, on EL7 and rawhide. That's why they come with built-in error handling. Regards, -- Nicolas Mailhot

short spec file of binary package
by Germano Massullo 01 Feb '18

01 Feb '18

Hi, I am studying packaging guidelines of binary software written in Go language. Actually am studying https://src.fedoraproject.org/rpms/syncthing/blob/master/f/syncthing.spec but I would like to read a shorter spec file. Which one do you recommend me to take as example in order to make some comparisons? Thank you

De: "Jakub Cajka" > Very nice list, it would be nice to have it as sub-wiki page of guidelines. I have took liberty to add > few points. Ok, I put it here so people have a place to work on it https://fedoraproject.org/wiki/More_Go_packaging#Go_developer_guidance:_mak… It can be moved later wherever you feel is more appropriate Regards, -- Nicolas Mailhot

Go 1.10 and PPC64LE builds
by esm＠logic.net 17 Jan '18

17 Jan '18

So like a lot of folks, I got an FTBFS when Go 1.10 landed in rawhide. After fixing things (some net/url changes bit this package's test suite), I have things building again, except on ppc64le: ``` + go test -compiler gc -ldflags ' -extldflags '\''-Wl,-z,relro -specs=/usr/lib/rpm/redhat/redhat-hardened-ld '\''' github.com/asaskevich/govalidator /tmp/go-build843430853/b001/govalidator.test: error while loading shared libraries: R_PPC64_ADDR16_HA reloc at 0x000000013c40ba9c for symbol `' out of range ``` From: https://koji.fedoraproject.org/koji/taskinfo?taskID=24219288 All other arches build fine. This smells like a problem with the ppc64le builder (or the go compiler on that platform), but wanted to bounce it off the list before I spend too much time digging into it. -Ed
