Summary: [ducktests] Stabilize Ducktests tox environments by
removing shared homedir usage
Key: IGNITE-28431
URL: https://issues.apache.org/jira/browse/IGNITE-28431
Project: Ignite
Issue Type: Task
Reporter: Maksim Davydov
Assignee: Maksim Davydov
The Ducktests codestyle/test step in CI occasionally fails due to corrupted or
inconsistent tox environments stored under a shared directory:
{code}
/home/teamcity/.virtualenvs/ignite-ducktests-*
{code}
This happens because the current tox configuration uses:
{code}
envdir = {homedir}/.virtualenvs/ignite-ducktests-{envname}
{code}
Since {homedir} resolves to the global $HOME directory (e.g., /home/teamcity),
multiple builds reuse the same environments. This leads to:
* Cross-build contamination
* Broken or partially created virtualenvs
* Non-deterministic failures (e.g., “cowardly refusing to delete envdir”)
* Increased flakiness in CI
*Proposed Solution*: Update tox configuration to use an isolated, per-checkout
environment directory
