This document is intended to provide a comprehensive checklist of tasks before, during, and after an Arrow release.
Preparing for the release
Before creating a source release, the release manager must ensure that any resolved JIRAs have the appropriate Fix Version set so that the changelog is generated properly.
To do this, search for the Arrow project and issues with no fix version. Click the "Tools" dropdown menu in the top right of the page and select "Bulk Change". Indicate that you wish to edit the issues, then set the correct Fix Version and apply the change. Remember to uncheck the box about "send e-mail notifications" to avoid excess spam to email@example.com.
Main source release and vote
Source release and vote
- You must not have any arrow-cpp or parquet-cpp environment variables defined except
CXXif you want to build with something other than GCC by default (e.g. clang).
- Being a committer to be able to push to dist and maven repository
- A GPG key in the Apache Web of Trust (cross signed by other Apache committers/PMC members) to sign the artifacts (If you have multiple GPG keys, you must set correct GPG key ID in
- Maven configured to publish artifacts to Apache repositories (see http://www.apache.org/dev/publishing-maven-artifacts.html)
- Need to setup a master password ~/.m2/settings-securty.xml (see https://maven.apache.org/guides/mini/guide-encryption.html)
- And settings.xml (see http://www.apache.org/dev/publishing-maven-artifacts.html#dev-env)
- Test it:
mvn clean install -Papache-release(I had to
to properly prompt for passphrase)
- Have the build requirements for cpp and c_glib installed (see their README)
- Set JIRA_USERNAME and JIRA_PASSWORD environment variables
en_US.UTF-8locale (You can confirm available locales by
- Install Python 3 as
- Create your account on Bintray
dev/release/.env.example. See the comments in
dev/release/.env.examplehow to set each variable.
- Request INFRA to add you to https://bintray.com/apache/ members. See also: - INFRA-18698Getting issue details... STATUS
- Setup crossbow as described in its README
- Have Docker and docker-compose installed
To build the source release, run the following (replace 0.1.0 with version to release):
Start the vote thread on firstname.lastname@example.org and supply instructions for verifying the integrity of the release. Approval requires a net of 3 +1 votes from PMC members. A release cannot be vetoed.
To set the mvn version in the poms
Reset your workspace
Delete tag locally
How to stage maven artifacts:
artifacts get staged during the perform phase of the scripts above.
If you need to stage the artifacts again follow the instructions bellow:
Test binary package upload with your own Bintray account:
Delete binary packages for the version:
After the release vote, we must undertake many tasks to update source artifacts, binary builds, and the Arrow website.
Be sure to go through on the following checklist:
Rebasing the master branch on local release branch
WARNING: do not rebase master on maintenance branches containing cherry-picked / backported commits e.g. patch releases
The "local release branch" is the "release-0.1.0-rc0" branch in the above "Source release and vote" section.
The local release branch has some unpushed commits such as bumping to the next snapshot version. So you need to add these commits to the master branch. This needs force push. You can do all things by the following command line:
Marking the released version as "RELEASED" on JIRA
- Open https://issues.apache.org/jira/plugins/servlet/project-config/ARROW/administer-versions
- Click "..." for the release version in "Actions" column
- Select "Release"
- Set "Release date"
- Click "Release" button
Starting the new version on JIRA
- Open https://issues.apache.org/jira/plugins/servlet/project-config/ARROW/administer-versions
- Click "..." for the next version in "Actions" column
- Select "Edit"
- Set "Start date"
- Click "Save" button
Updating the Arrow website
The website is a Jekyll project in hosting in https://github.com/apache/apache-site repository. As part of updating the website, we must perform various subtasks.
- Fork the apache-site repository and clone it next to the arrow repository.
Generate the release note:
- Create a pull-request and a Jira with the links the script shows at the end.
Finally, if appropriate, write a short blog post summarizing the new release highlights. Here is an example.
site/README.md how to publish. (TODO: Should we move the document to this Wiki?)
Uploading source release artifacts to SVN
A PMC member must commit the source release artifacts to SVN:
Uploading binary release artifacts to Bintray
A PMC member must upload the binary release artifacts to Bintray:
You can test with your Bintray repository by specifying
BINTRAY_ACCOUNT environment variable:
Add relevant release data for Arrow to https://reporter.apache.org.
Write a release announcement (see example) and send to email@example.com and firstname.lastname@example.org. The announcement to email@example.com must be sent from your apache.org e-mail address to be accepted.
Updating website with new API documentation
This script assumes that a
dist directory can be created at the same level by the current user. Please note that most of the software must be built in order to create the documentation, so this step may take some time to run, especially the first time around as the Docker container will also have to be built.
To upload the updated documentation to the website, navigate to
site/asf-site and commit all changes:
After successfully creating the API documentation the website can be run locally to browse the API documentation from the top level
Documentation menu. To run the website issue the command:
The local URL for the website running inside the docker container will be shown as
Server address: in the output of the command. To stop the server press
Ctrl-C in that window.
Updating C++ and Python packages
We have been making Arrow available to C++ and Python users on the 3 major platforms (Linux, macOS, and Windows) via two package managers: pip and conda.
Updating Python Artifacts
pip binary packages (called "wheels") are built using the
crossbow tool that we used above during the release candidate creation process and then uploaded to PyPI (PYthon Package Index) under the
We use the
twine tool to upload wheels to PyPI:
Please make sure you use
twine >= 1.11.0. This supports the markdown long description in setup.py which also requires
setuptools >= 38.6.0.
You must have the correct permissions on PyPI to upload wheels; ask Wes McKinney or Uwe Korn if you need help with this.
We have been building conda packages using conda-forge. The three "feedstocks" that must be updated in-order are:
parquet-cpp-feedstock(it is a meta package which installs pyarrow, no need to update until parquet's version is bumped)
To update a feedstock, open a pull request updating
recipe/meta.yaml as appropriate. Once you are confident that the build is good and the metadata is updated properly, merge the pull request. You must wait until the results of each of the feedstocks land in anaconda.org before moving on to the next package.
Unfortunately, you cannot open pull requests to all three repositories at the same time because they are interdependent.
Updating Homebrew packages
We have been building brew packages:
In order to update the formulas, follow the Homebrew guide:
Updating Java Maven artifacts in Maven central
How to publish the staged artifacts:
Logon to the apache repository: https://repository.apache.org/#stagingRepositories
Select the arrow staging repository you just just created: orgapachearrow-100x
Click the "close" button
Once validation has passed, click the "release" button
You must set up Maven to be able to publish to Apache's repositories. Read more at https://www.apache.org/dev/publishing-maven-artifacts.html.
Updating Ruby packages
You need an account on https://rubygems.org/ to release Ruby packages.
If you have an account on https://rubygems.org/ , you need to join owners of red-arrow gem, red-arrow-cuda gem, red-plasma gem, red-gandiva gem and red-parquet gem. Existing owners can add a new account to the owners of them by the following command lines:
You can update Ruby packages when you join owners of them:
In order to publish the binary build to npm you will need to get access to the project by asking one of the current collaborators listed at https://www.npmjs.com/package/apache-arrow
When you have access you can publish releases to npm by running the npm-release.sh script inside the JS source release:
Updating .NET NuGet packages
You need an account on https://www.nuget.org/. You need to join owners of Apache.Arrow package. Existing owners can invite you to the owners at https://www.nuget.org/packages/Apache.Arrow/Manage .
You need to create an API key at https://www.nuget.org/account/apikeys to upload from command line.
Install the latest .NET Core SDK from https://dotnet.microsoft.com/download.
Updating Rust packages
You need permissions to the arrow, parquet and datafusion crates on crates.io to publish the Rust artifacts.
Updating R packages
To publish the R package on CRAN, there are a few steps we need to do first in order to ensure that binaries for Windows and macOS are available to CRAN.
All of these repositories are maintained by Jeroen Ooms <firstname.lastname@example.org>. He may notice that the Apache Arrow release has been approved and make these patches on his own; otherwise, he's the one who will need to accept the pull requests.
- Update the "autobrew" formula, a fork of Homebrew that is used in R package configure scripts to pull system dependencies on CRAN, where Homebrew is not available. Make a pull request to modify https://github.com/autobrew/homebrew-core/blob/master/Formula/apache-arrow.rb to update the version, SHA, and any changes to dependencies and build steps. Those dependency/build updates will have been already recorded in the copy we have of that formula in dev/tasks/homebrew-formulae/autobrew/apache-arrow.rb. This formula could be the same as the official Homebrew formula, but historically it has been a slimmer build of the C++ library (no Gandiva, for example). Note that making this pull request is not sufficient. The "bottles" will need to be built as well, and this is currently done on a bespoke VM that Jeroen has. But, making this pull request will give Jeroen the information he needs to do that part. If there are new dependencies, you'll also need to update the script at https://github.com/jeroen/autobrew/blob/gh-pages/apache-arrow to include any additions made to r/tools/autobrew. (These local copies of the autobrew scripts are tested in the nightly R package builds.)
- Update the analogous build scripts for Windows, found in two locations: (1) rtools-packages, https://github.com/r-windows/rtools-packages/blob/master/mingw-w64-arrow/PKGBUILD; and (2) rtools-backports, https://github.com/r-windows/rtools-backports/blob/master/mingw-w64-arrow/PKGBUILD. (These use the current and future RTools toolchains for compiling libraries on Windows for use in R. See the rtools-backports readme and things it links to for some context.) Update those PKGBUILD scripts with the latest version and SHA, and adapt any build step changes in the new release from the ci/PKGBUILD file in apache/arrow, from which these scripts are based.
- Update "rwinlib", the repository where binary packages compiled especially for R on Windows are customarily hosted, after those two rtools PRs are merged: https://github.com/rwinlib/arrow. (When the R package is installed on Windows, the rwinlib library gets downloaded in this R script, which is called in configure.win). The rtools-backports repository generates build artifacts that go into the rwinlib package. Our best understanding of how that happens is captured in ci/windows-pkg-arrow-for-r.sh, which is called in the apache/arrow Appveyor job. You may be able to download the
build\arrow-x.y.z.zipartifact (see here for an example of the Appveyor build artifacts), which that script creates, from our R Appveyor job from the release tag and use that for this submission. Most likely, Jeroen will handle this himself after the rtools-packages/backports PRs are merged.
Once these binary prerequisites have been satisfied, we can submit to CRAN. Given the vagaries of the process, it is best if the R developers on the project verify the CRAN-worthiness of the package before submitting. Our CI systems give us some coverage for the things that CRAN checks, but there are a couple of final tests we should do to confirm that the release binaries will work and that everything runs on the same infrastructure that CRAN has, which is difficult/impossible to emulate fully on Travis or with Docker.
Build the R package locally (
R CMD build . from within the
r/ directory) and do these checks:
- Use R-hub for the "usual" CRAN incoming checks. R-hub works hard to match the build environments that CRAN uses and provides a services for checking packages. From within an R session, rhub::check_for_cran() will trigger several builds, or you can specify them individually in the web app.
- It's also good to do a macOS check on R-hub (not part of the
check_for_cran()suite) to verify the "autobrew" formula. R-hub has a good approximation of the dated macOS setup that CRAN uses, which is seemingly not possible to reproduce on Travis.
- For Windows, submit the built package to the Winbuilder service and check the package for R-devel, the development version of R. R-hub has Windows infrastructure but winbuilder is the exact setup that CRAN uses and catches things that R-hub doesn't.
If those are clean, let's submit. CRAN has a web form for uploading packages. The release process requires email confirmation from the R package maintainer, currently Neal Richardson.
Updating MSYS2 package
You need to send a pull request to https://github.com/msys2/MINGW-packages to upgrade mingw-w64-arrow package. At least you need to update
sha256sums . If there are changes for build option, you may need to update CMake options and Meson options.
See https://github.com/msys2/MINGW-packages/pull/6175 for example.
Removing source artifacts for RC
Source artifacts for RC are needless when all release tasks for the version are finished. We can remove source artifacts for RC by the following command line:
