#3423 Fix release pipeline failures Pull request opened by pingsutw Tracking Issue N/A - operational fix for release pipeline Why are the changes needed? The v1.16.17 release pipeline failed due to multiple issues: 1. Transient PyPI connection error: The

flytekitplugins_dask

upload hung for 4 minutes during plugin publishing, then PyPI dropped the connection (

RemoteDisconnected

). This killed the entire

deploy

job, causing all Docker image builds to be skipped. 2. Re-runs are not idempotent: Re-running the failed workflow fails immediately because

twine upload

returns

400 Bad Request

for already-uploaded packages. 3.

build_image.yml

passes

github.sha

as VERSION: The manual image build workflow passed the commit SHA as the PyPI version, which is not a valid PEP 440 version string, causing

uv pip install flytekit==<sha>

to fail. 4. Unstable Python version:

actions/setup-python@v1

with

python-version: "3.x"

resolved to Python 3.14.3, which is brand new and potentially unstable for building release artifacts. What changes were made?

pythonpublish.yml

• Upgrade

actions/setup-python

from v1 to v5 • Pin Python to 3.12 instead of

3.x

• Add

--verbose --skip-existing

to

twine upload

so re-runs skip already-uploaded packages • Use safer shell parameter expansion (

${GITHUB_REF#refs/tags/v}

) instead of piping through

sed

build_image.yml

• Add

get-version

job that extracts the semver from the branch/tag name (strips

v

prefix) • All image build jobs now use the extracted version instead of

github.sha

as the

VERSION

build arg • Add version-based image tags alongside SHA-based tags

plugins/Makefile

• Add

--verbose --skip-existing

to both

twine upload

commands How was this tested?
