Dear mirror admins, Due to a bug in rsync versions 3.2.0 to 3.2.3 (inclusive), the use of --delay-updates can leave behind .~tmp~ directories containing updated files that never make it out of the temporary location. [1] This issue has led to outdated repo databases and lastupdate files in the past. Last year, the syncrepo-template.sh script (linked from the wiki [2]) was updated to remove any existing .~tmp~ directories before calling rsync. This workaround is needed if you use rsync 3.2.0 - 3.2.3. Arch's rsync 3.2.3-4 package has been patched for this problem so the workaround is not required for mirrors running on Arch. The syncrepo-template.sh script was just updated again to replace --delete-after with --delete-delay (as a performance optimization) and to stop using a temporary directory for file transfers. The exact commits (with accompanying commit messages) can be found at [3] (ignore the first and last commit which are specific to Arch's infra). To avoid having mirrors with stale repositories because of the .~tmp~ issue, please rebase your syncrepo script to match the latest version of the template obtained through the link in the wiki. If you don't use rsync 3.2.0 - 3.2.3 (or use Arch's patched version), feel free to comment out the .~tmp~ workaround.
