Packaging Node.js

These instructions are applicable as of 2023-04-27, following the implementation of https://www.fedoraproject.org/wiki/Changes/NodejsRepackaging

Basic steps to update to a new release

1. Run the following command to automatically update the specfile and SOURCES:

   ./nodejs-sources 20.1.0
   

   This will download the tarball from nodejs.org, strip out the bundled OpenSSL code, extract the versions of the bundled sources, pull down the ICU data files and update the spec file with this new information, also pushing the rebuilt tarball into the Fedora lookaside cache.

2. Verify that the patches still apply by running fedpkg prep. If they do not, follow the steps under "Resolving Patch Conflicts".

3. (Preferred) Perform a scratch-build on at least one architecture

   fedpkg scratch-build [--arch x86_64] --srpm
   

   Verify that it built successfully.

4. Commit the code locally and push it to all active Fedora branches.

   git commit -sam "Update to version 20.1.0"
   

   git push origin rawhide rawhide:f38 rawhide:f37
   

5. Build for all active Fedora branches

   for i in f37 f38 rawhide ; do fedpkg --release $i build --nowait ; done
   

Basic steps to update the packaging

1. Make all changes in the packaging/nodejs.spec.j2 file.

2. When finished, run

   ./nodejs-sources 20.1.0 --no-push
   

   which will regenerate the nodejs20.spec file with the appropriate values. The --no-push argument is used to avoid uploading a new tarball to the lookaside cache.¹

3. (Preferred) Perform a scratch-build on at least one architecture

   fedpkg scratch-build [--arch x86_64] --srpm
   

   Verify that it built successfully.

4. Commit the code locally and push it to all active Fedora branches.

   git commit -sam "Update to version 20.1.0"
   

   git push origin rawhide rawhide:f38 rawhide:f37
   

5. Build for all active Fedora branches

   for i in f37 f38 rawhide ; do fedpkg --release $i build --nowait ; done
   

Resolving Patch Conflicts

1. Clone the upstream Node.js repository

   git clone -o upstream git://github.com/nodejs/node.git nodejs-upstream
   

2. Rebase the Fedora patches atop the latest release

   pushd nodejs-upstream
   

   git checkout -b fedora-v20 v20.1.0
   

   git am -3 ../nodejs-fedora/*.patch
   

   If the patches do not apply cleanly, resolve the merges appropriately. Once they have all been applied, output them again:

   git format-patch -M --patience --full-index -o ../nodejs20 v20.1.0..HEAD
   

   popd
   

3. Resume the basic process.

---

1. Due to non-deterministic behavior, stripping out the OpenSSL bits from the upstream tarball and recompressing it will result in a different checksum hash. This isn't harmful, but wastes bandwidth and storage space, so use --no-push when possible. ↩︎
