a cli tool to ease Fedora Packager workflow

Fed Brunch (pronounced "F br{a,u}nch")

fbrnch: Fedora branches packaging tool

  • list, create and update package reviews from spec files
    • repo request and import directly from bugzilla review
  • build packages
    • merging branches & pushing updates to Bodhi
  • handles both dist-git and non-distgit:
    • koji scratch builds
    • prep/local/srpm/install/mock packages locally
  • automated parallel koji builds in dependency layers
  • diff local changes (when changing many packages)
  • show package status and bugs
  • push incremental Copr builds

History

  • started off as "fedbrnch"

    • (harder to type and complete)

  • simple initial goal of building fedora packages across branches

    • repetitive work which can be largely automated

  • then added support for Package Review workflow

  • and automatic bodhi updates

  • many of the build related features were initially implemented in fedora-haskell-tools

Use case: Package Reviews (1)

Package Review creation:

[pkg]$ fbrnch create-review
  • check package name same as specfile
  • pre-checks for any existing reviews
  • creates srpm from spec file (prevents out of sync)
  • runs rpmlint and optionally mock
  • uploads spec & srpm and creates review bug (like fedora-create-review)

Use case: Package Reviews (2)

Package Review update:

[pkg]$ fbrnch update-review
  • creates srpm from spec
  • runs rpmlint and optionally mock
  • uploads spec & srpm and updates the review bug

Use case: Package Reviews (3)

Package Reviews status:

$ fbrnch reviews

lists your open package reviews

Also: find-review

Use case: Building

$ fbrnch build -B pkg1 pkg2 pkg3

builds packages over all their active branches

  • offers to merge newer branch and push
  • checks against existing Koji build
  • checks for krb5 ticket
  • creates Bodhi update (except Rawhide)
  • optionally does override tag and waitrepo
$ fbrnch build -b master -b f32 mypkg

Local actions (both dist-git and not)

[pkg]$ fbrnch local

$ fbrnch install pkg1 pkg2 pkg3

Other local actions:

  • clone, merge, commit, pull
  • srpm, sort, prep, mock, install-deps, diff

Demos - done

Full disclosure

fbrnch is written in Haskell

"Reads" (queries) Fedora services natively

  • (pending release) pagure, koji, bodhi, copr
  • (released) bugzilla-redhat

But currently still "writes" through the python clients

  • fedpkg, bodhi, koji, copr

Parallel building

  • uses Haskell async library

  • rpmbuild-order handles dependency graphs, sorting, and layers

$ fbrnch parallel -b master -t f33-build-side-345 *

sorts and builds packages in dependency layers

You may also like

cobrnch for staggered copr builds

So I added it as a copr command to fbrnch

$ fbrnch copr -b master -b f32 project mypkg

Thanks

😃 Thank you to the early adopters and testers:

  • Tristan de Cacqueray (tristanC)
  • Mike Fabian (mfabian)
  • Elliott Sales de Andrade (qulogic)
  • Dan Čermák (defolos)
  • and others

What's next

package fbrnch for Fedora
