vclock — A Go Vector Clock Implementation

This repository is a stripped-down version of the brilliant DistributedClocks/GoVector library. Unfortunately, the original library is outdated and has a few bugs that make its use impossible. This library is created as a drop-in replacement for github.com/DistributedClocks/GoVector/govec/vclock. Other functionality of the package is not implemented.

As of now, these are the major changes:

• include a working go.mod file with a specific tag
• fix a bug where ReturnVCString is non-deterministic (see this PR)
• fix a subtle bug in the vector clock comparison function (see this issue)
• introduce an Order() function that returns the relationship of two vector clocks, based on the Voldemort implementation of vector clocks
• improve documentation

To use this package in your code, download the latest version:

go get git.tu-berlin.de/mcc-fred/vclock

Then replace your import directives from

import (
    "github.com/DistributedClocks/GoVector/govec/vclock"
)

to

import (
    "git.tu-berlin.de/mcc-fred/vclock"
)

All code continues to be licensed under the MIT license.

Note that most development is done on the TU Berlin GitLab instance. A GitHub mirror is provided for convenience.
