pagehelper project pagehelper UPGRADE

Affected: >= 1.0 and <= 3.7.0 · >= 4.0.0 and <= 5.0.0 · >= 5.1.0 and <= 5.3.0

Fixed in: newer than 5.3.0

Safe to downgrade to: a release before 1.0

1. Check installed version

apt-cache policy pagehelper || rpm -q pagehelper || pagehelper --version

2. UPGRADE to newer than 5.3.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade pagehelper

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade pagehelper

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 1.0 (Debian / Ubuntu)

apt-cache madison pagehelper sudo apt install pagehelper=<VERSION_BEFORE_1.0> sudo apt-mark hold pagehelper

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list pagehelper sudo dnf downgrade pagehelper-<VERSION_BEFORE_1.0> sudo dnf versionlock add pagehelper

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
