(iggy) branch ci/path-gate-coverage-baseline updated (1f14401ea -> e1bd5060d)
This is an automated email from the ASF dual-hosted git repository.
hubcio pushed a change to branch ci/path-gate-coverage-baseline
in repository https://gitbox.apache.org/repos/asf/iggy.git
omit 1f14401ea ci: skip unaffected language jobs in coverage baseline
new e1bd5060d ci: skip unaffected language jobs in coverage baseline
This update added new revisions after undoing existing revisions.
That is to say, some revisions that were in the old version of the
branch are not in the new version. This situation occurs
when a user --force pushes a change and generates a repository
containing something like this:
* -- * -- B -- O -- O -- O (1f14401ea)
\
N -- N -- N refs/heads/ci/path-gate-coverage-baseline (e1bd5060d)
You should already have received notification emails for all of the O
revisions, and so the following emails describe only the N revisions
from the common base, B.
Any revisions marked "omit" are not gone; other references still
refer to them. Any revisions marked "discard" are gone forever.
The 1 revisions listed above as "new" are entirely new to this
repository and will be described in separate emails. The revisions
listed as "add" were already present in the repository and have only
been added to this reference.

ci: skip unaffected language jobs in coverage baseline
Every master push ran all 7 language coverage suites plus the
macOS cache warm (~55 runner-minutes) even when the push touched
a single SDK or only docs. Every Codecov flag has carryforward
enabled and all statuses are informational, so re-measuring
untouched languages re-uploads identical data.
A detect job now diffs the push range and gates each job on the
paths feeding its Codecov flag; untouched flags carry forward
their previous master report. The differ fails open to a full
run on any uncertainty (initial push, force push, CI or tooling
changes), and a new workflow_dispatch trigger forces a full
baseline on demand. The macOS cache warm follows the rust gate
since that cache only goes stale when Rust sources change.
