Qt 5 Maintainer's Notes

Minor Updates

Let $major be the major version number, e.g. 5.9.

  1. Change the version number in the $major/fetch.sh.
  2. Run ./maintainers/scripts/fetch-kde-qt.sh pkgs/development/qt-5/$major from the top of the Nixpkgs tree.

See below if it is necessary to update any patches.

Major Updates

Let $major be the new major version number, e.g. 5.10.

  1. Copy the subdirectory from the previous major version to $major.
  2. Change the version number in $major/fetch.sh.
  3. Run ./maintainers/scripts/fetch-kde-qt.sh pkgs/development/qt-5/$major from the top of the Nixpkgs tree.
  4. Add a top-level attribute in pkgs/top-level/all-packages.nix for the new major version.
  5. Change the qt5 top-level attribute to point to the new major version.
  6. If the previous major version is not a long-term support release, remove it from Nixpkgs.

See below if it is necessary to update any patches.

Patches

Nixpkgs maintains several patches for Qt which cannot be submitted upstream. To facilitate maintenance, a fork of the upstream repository is created for each patched module:

In each repository, the patches are contained in a branch named nixpkgs/$major for each major version. Please make a pull request to add or update any patch which will be maintained in Nixpkgs.

The forked repository for each module is used to create a single patch in Nixpkgs. To recreate the patch for module $module (e.g. qtbase) at version $version (e.g. 5.9.1) in the branch $major (e.g. 5.9),

  1. Clone the fork for $module from the list above.
  2. Checkout the active branch, git checkout nixpkgs/$major.
  3. Compare the patched branch to the release tag, git diff v$version > $module.patch.
  4. Copy $module.patch into the Nixpkgs tree.

Minor Version Updates

To update module $module to version $version from an older version in the same branch $major,

  1. Clone the fork for $module from the list above.
  2. Checkout the active branch, git checkout nixpkgs/$major.
  3. Merge the new version into the active branch, git merge --no-ff v$version.
  4. Fix any conflicts.
  5. Open a pull request for the changes.
  6. Follow the instructions above to recreate the module patch in Nixpkgs.

Major Version Updates

To update module $module from $oldversion in branch $oldmajor to version $version in branch $major,

  1. Clone the fork for $module from the list above.
  2. Checkout a new branch for the new major version, git checkout -b nixpkgs/$major nixpkgs/$oldmajor.
  3. Rebase the patches from $oldversion onto the new branch, git rebase v$oldversion --onto v$version.
  4. Fix any conflicts.
  5. Open a pull request for the changes.
  6. Follow the instructions above to recreate the module patch in Nixpkgs.
