Gentoo repository for Precizer

Русская версия

This repository is an external Gentoo ebuild repository for installing Precizer through Portage

Precizer is a lightweight, high-performance CLI tool written in C for file integrity verification and comparison. It walks directory trees, calculates SHA512 checksums, and stores the results in an SQLite database. Databases can be compared with each other to find missing files and files with different contents

The tool is useful for validating synchronization results, backups, and Disaster Recovery scenarios. Precizer does not modify, delete, or move the files being checked. All working data is written only to the Precizer database

Enable the Repository

Run the commands as root

emerge --ask --noreplace dev-vcs/git
install -d /etc/portage/repos.conf
cat >/etc/portage/repos.conf/precizer.conf <<'EOF'
[precizer]
location = /var/db/repos/precizer
sync-type = git
sync-uri = https://github.com/precizer/gentoo-overlay.git
auto-sync = yes
EOF
emaint sync --repo precizer

Install

emerge --ask app-forensics/precizer
precizer --version

Install with Tests

To build the package and run the tests from the ebuild, enable the test USE flag and the test Portage feature for this invocation

USE="test" FEATURES="test" emerge --ask app-forensics/precizer
precizer --version

USE=test allows the test phase for app-forensics/precizer, and FEATURES=test tells Portage to actually run tests during the build

Update

To update only this repository, use

emaint sync --repo precizer

After syncing, update the package in the usual way

emerge --ask --update app-forensics/precizer

emerge --sync will also synchronize this repository because auto-sync = yes is enabled for it

Disable

emerge --ask --depclean app-forensics/precizer
rm -f /etc/portage/repos.conf/precizer.conf
rm -rf /var/db/repos/precizer
