The code is based on the Go based PHaul +implementation from the CRIU repository. For easier inclusion into other Go projects the +CRIU Go bindings have been moved to this repository. + +The Go bindings provide an easy way to use the CRIU RPC calls from Go without the need +to set up all the infrastructure to make the actual RPC connection to CRIU. + +The following example would print the version of CRIU: +``` + c := criu.MakeCriu() + version, err := c.GetCriuVersion() + fmt.Println(version) +``` +or to just check if at least a certain CRIU version is installed: +``` + c := criu.MakeCriu() + result, err := c.IsCriuAtLeast(31100) +``` + +## Releases + +The first go-criu release was 3.11 based on CRIU 3.11. The initial plan +was to follow CRIU so that go-criu would carry the same version number as +CRIU. + +As go-criu is imported in other projects and as Go modules are expected +to follow Semantic Versioning go-criu will also follow Semantic Versioning +starting with the 4.0.0 release. + +4.0.0 is based on CRIU 3.14 + +## How to contribute + +While bug fixes can first be identified via an "issue", that is not required. +It's ok to just open up a PR with the fix, but make sure you include the same +information you would have included in an issue - like how to reproduce it. + +PRs for new features should include some background on what use cases the +new code is trying to address. When possible and when it makes sense, try to +break-up larger PRs into smaller ones - it's easier to review smaller +code changes. But only if those smaller ones make sense as stand-alone PRs. + +Regardless of the type of PR, all PRs should include: +* well documented code changes +* additional testcases. Ideally, they should fail w/o your code change applied +* documentation changes + +Squash your commits into logical pieces of work that might want to be reviewed +separate from the rest of the PRs. Ideally, each commit should implement a +single idea, and the PR branch should pass the tests at every commit. GitHub +makes it easy to review the cumulative effect of many commits; so, when in +doubt, use smaller commits. + +PRs that fix issues should include a reference like `Closes #XXXX` in the +commit message so that github will automatically close the referenced issue +when the PR is merged. + +Contributors must assert that they are in compliance with the [Developer +Certificate of Origin 1.1](http://developercertificate.org/). This is achieved +by adding a "Signed-off-by" line containing the contributor's name and e-mail +to every commit message. Your signature certifies that you wrote the patch or +otherwise have the right to pass it on as an open-source patch. + +### License and copyright + +Unless mentioned otherwise in a specific file's header, all code in +this project is released under the Apache 2.0 license. + +The author of a change remains the copyright holder of their code +(no copyright assignment).

If the API version specified in + the URL is not supported by the daemon, a HTTP `400 Bad Request` error message + is returned. + + If you omit the version-prefix, the current version of the API (v1.40) is used. + For example, calling `/info` is the same as calling `/v1.40/info`.

The stream consists of a series of frames, each + containing a header and a payload. + + The header contains the information which the stream writes (`stdout` or + `stderr`). It also contains the size of the associated frame encoded in + the last four bytes (`uint32`). + + It is encoded on the first eight bytes like this: + + ```go + header := [8]byte{STREAM_TYPE, 0, 0, 0, SIZE1, SIZE2, SIZE3, SIZE4} + ``` + + `STREAM_TYPE` can be: + + - 0: `stdin` (is written on `stdout`) + - 1: `stdout` + - 2: `stderr` + + `SIZE1, SIZE2, SIZE3, SIZE4` are the four bytes of the `uint32` size + encoded as big endian. + + Following the header is the payload, which is the specified number of + bytes of `STREAM_TYPE`. + + The simplest way to implement this protocol is the following: + + 1. Read 8 bytes. + 2. Choose `stdout` or `stderr` depending on the first byte. + 3. Extract the frame size from the last four bytes. + 4. Read the extracted size and output it on the correct output. + 5. Goto 1. + + ### Stream format when using a TTY + + When the TTY setting is enabled in [`POST /containers/create`](#operation/ContainerCreate), + the stream is not multiplexed.
