# zrepl
|
||||
zrepl is a one-stop ZFS backup & replication solution.
|
||||
|
||||
## User Documentation
|
||||
|
||||
**User Documentation** can be found at [zrepl.github.io](https://zrepl.github.io).
|
||||
|
||||
## Bug Reports
|
||||
|
||||
1. If the issue is reproducible, enable debug logging, reproduce and capture the log.
|
||||
2. Open an issue on GitHub, with logs pasted as GitHub gists / inline.
|
||||
|
||||
## Feature Requests
|
||||
|
||||
1. Does your feature request require default values / some kind of configuration?
|
||||
If so, think of an expressive configuration example.
|
||||
2. Think of at least one use case that generalizes from your concrete application.
|
||||
3. Open an issue on GitHub with example conf & use case attached.
|
||||
4. **Optional**: [Post a bounty](https://www.bountysource.com/teams/zrepl) on the issue, or [contact Christian Schwarz](https://cschwarz.com) for contract work.
|
||||
|
||||
The above does not apply if you already implemented everything.
|
||||
Check out the *Coding Workflow* section below for details.
|
||||
|
||||
## Building, Releasing, Downstream-Packaging
|
||||
|
||||
This section provides an overview of the zrepl build & release process.
|
||||
Check out `docs/installation/compile-from-source.rst` for build-from-source instructions.
|
||||
|
||||
### Overview
|
||||
|
||||
zrepl is written in [Go](https://golang.org) and uses [Go modules](https://github.com/golang/go/wiki/Modules) to manage dependencies.
|
||||
The documentation is written in [ReStructured Text](http://docutils.sourceforge.net/rst.html) using the [Sphinx](https://www.sphinx-doc.org) framework.
|
||||
|
||||
Install **build dependencies** using `./lazy.sh devsetup`.
|
||||
`lazy.sh` uses `python3-pip` to fetch the build dependencies for the docs - you might want to use a [venv](https://docs.python.org/3/library/venv.html).
|
||||
If you just want to install the Go dependencies, run `./lazy.sh godep`.
|
||||
|
||||
The **test suite** is split into pure **Go tests** (`make test-go`) and **platform tests** that interact with ZFS and thus generally **require root privileges** (`sudo make test-platform`).
|
||||
Platform tests run on their own pool with the name `zreplplatformtest`, which is created using the file vdev in `/tmp`.
|
||||
|
||||
For a full **code coverage** profile, run `make test-go COVER=1 && sudo make test-platform && make cover-merge`.
|
||||
An HTML report can be generated using `make cover-html`.
|
||||
|
||||
**Code generation** is triggered by `make generate`. Generated code is committed to the source tree.
|
||||
|
||||
### Build & Release Process
|
||||
|
||||
**The `Makefile` is catering to the needs of developers & CI, not distro packagers**.
|
||||
It provides phony targets for
|
||||
* local development (building, running tests, etc)
|
||||
* building a release in Docker (used by the CI & release management)
|
||||
* building .deb and .rpm packages out of the release artifacts.
|
||||
|
||||
**Build tooling & dependencies** are documented as code in `lazy.sh`.
|
||||
Go dependencies are then fetched by the go command and pip dependencies are pinned through a `requirements.txt`.
|
||||
|
||||
**We use CircleCI for continuous integration**.
|
||||
There are two workflows:
|
||||
|
||||
* `ci` runs for every commit / branch / tag pushed to GitHub.
|
||||
It is supposed to run very fast (<5min and provides quick feedback to developers).
|
||||
It runs formatting checks, lints and tests on the most important OSes / architectures.
|
||||
Artifacts are published to minio.cschwarz.com (see GitHub Commit Status).
|
||||
|
||||
* `release` runs
|
||||
* on manual triggers through the CircleCI API (in order to produce a release)
|
||||
* periodically on `master`
|
||||
Artifacts are published to minio.cschwarz.com (see GitHub Commit Status).
|
||||
|
||||
**Releases** are issued via Git tags + GitHub Releases feature.
|
||||
The procedure to issue a release is as follows:
|
||||
* Issue the source release:
|
||||
* Git tag the release on the `master` branch.
|
||||
* Push the tag.
|
||||
* Run `./docs/publish.sh` to re-build & push zrepl.github.io.
|
||||
* Issue the official binary release:
|
||||
* Run the `release` pipeline (triggered via CircleCI API)
|
||||
* Download the artifacts to the release manager's machine.
|
||||
* Create a GitHub release, edit the changelog, upload all the release artifacts, including .rpm and .deb files.
|
||||
* Issue the GitHub release.
|
||||
* Add the .rpm and .deb files to the official zrepl repos, publish those.
|
||||
|
||||
**Official binary releases are not re-built when Go receives an update. If the Go update is critical to zrepl (e.g. a Go security update that affects zrepl), we'd issue a new source release**.
|
||||
The rationale for this is that whereas distros provide a mechanism for this (`$zrepl_source_release-$distro_package_revision`), GitHub Releases doesn't which means we'd need to update the existing GitHub release's assets, which nobody would notice (no RSS feed updates, etc.).
|
||||
Downstream packagers can read the changelog to determine whether they want to push that minor release into their distro or simply skip it.
|
||||
|
||||
### Additional Notes to Distro Package Maintainers
|
||||
|
||||
* Use `sudo make test-platform-bin && sudo make test-platform` **on a test system** to validate that zrepl's abstractions on top of ZFS work with the system ZFS.
|
||||
* Ship a default config that adheres to your distro's `hier` and logging system.
|
||||
* Ship a service manager file and _please_ try to upstream it to this repository.
|
||||
* `dist/systemd` contains a Systemd unit template.
|
||||
* Ship other material provided in `./dist`, e.g. in `/usr/share/zrepl/`.
|
||||
* Have a look at the `Makefile`'s `ZREPL_VERSION` variable and how it passed to Go's `ldFlags`.
|
||||
This is how `zrepl version` knows what version number to show.
|
||||
Your build system should set the `ldFlags` flags appropriately and add a prefix or suffix that indicates that the given zrepl binary is a distro build, not an official one.
|
||||
* Make sure you are informed about new zrepl versions, e.g. by subscribing to GitHub's release RSS feed.
|
||||
|
||||
|
||||
## Contributing Code
|
||||
|
||||
* Open an issue when starting to hack on a new feature
|
||||
* Commits should reference the issue they are related to
|
||||
* Docs improvements not documenting new features do not require an issue.
|
||||
|
||||
### Breaking Changes
|
||||
|
||||
Backward-incompatible changes must be documented in the git commit message and are listed in `docs/changelog.rst`.
|
||||
|
||||
### Glossary & Naming Inconsistencies
|
||||
|
||||
In ZFS, *dataset* refers to the objects *filesystem*, *ZVOL* and *snapshot*. <br />
|
||||
However, we need a word for *filesystem* & *ZVOL* but not a snapshot, bookmark, etc.
|
||||
|
||||
Toward the user, the following terminology is used:
|
||||
|
||||
* **filesystem**: a ZFS filesystem or a ZVOL
|
||||
* **filesystem version**: a ZFS snapshot or a bookmark
|
||||
|
||||
Sadly, the zrepl implementation is inconsistent in its use of these words:
|
||||
variables and types are often named *dataset* when they in fact refer to a *filesystem*.
|
||||
|
||||
There will not be a big refactoring (an attempt was made, but it's destroying too much history without much gain).
|
||||
|
||||
However, new contributions & patches should fix naming without further notice in the commit message.
|
||||
ZFS dataset replication. Not a shell script.

// Package hooks implements pre- and post snapshot hooks.

// The Hook interface requires a hook to provide a Filesystems() filter, which doesn't make sense for

//
|

// Then create a CallbackHook using NewCallbackHookForFilesystem().
|

//
|

// Pass all of the above to NewPlan() which provides a Report() and Run() method:
|
||||
//
|
||||
// Plan.Run(ctx context.Context,dryRun bool) executes the plan and take a context as argument that should contain a logger added using hooks.WithLogger()).
|

// The value of dryRun is passed through to the hooks' Run() method.
|
||||
// Command hooks make it available in the environment variable ZREPL_DRYRUN.
|

//
|

// Plan.Report() can be called while Plan.Run() is executing to give an overview of plan execution progress (future use in "zrepl status").
