# README.md
|
||||
|
||||
This directory holds build scripts for unofficial, unsupported
|
||||
distributions of Go+BoringCrypto.
|
||||
|
||||
## Version strings
|
||||
|
||||
The distribution name for a Go+BoringCrypto release has the form `<GoVersion>b<BoringCryptoVersion>`,
|
||||
where `<GoVersion>` is the Go version the release is based on, and `<BoringCryptoVersion>` is
|
||||
an integer that increments each time there is a new release with different BoringCrypto bits.
|
||||
The `<BoringCryptoVersion>` is stored in the `VERSION` file in this directory.
|
||||
|
||||
For example, the first release is based on Go 1.8.3 is `go1.8.3b1`.
|
||||
If the BoringCrypto bits are updated, the next would be `go1.8.3b2`.
|
||||
If, after that, Go 1.9 is released and the same BoringCrypto code added to it,
|
||||
that would result in `go1.9b2`. There would likely not be a `go1.9b1`,
|
||||
since that would indicate Go 1.9 with the older BoringCrypto code.
|
||||
|
||||
## Releases
|
||||
|
||||
The `build.release` script prepares a binary release and publishes it in Google Cloud Storage
|
||||
at `gs://go-boringcrypto/`, making it available for download at
|
||||
`https://go-boringcrypto.storage.googleapis.com/<FILE>`.
|
||||
The script records each published release in the `RELEASES` file in this directory.
|
||||
|
||||
The `build.docker` script, which must be run after `build.release`, prepares a Docker image
|
||||
and publishes it on hub.docker.com in the goboring organization.
|
||||
`go1.8.3b1` is published as `goboring/golang:1.8.3b1`.
|
||||
|
||||
## Release process
|
||||
|
||||
1. If the BoringCrypto bits have been updated, increment the number in `VERSION`,
|
||||
send that change out as a CL for review, get it committed, and run `git sync`.
|
||||
|
||||
2. Run `build.release`, which will determine the base Go version and the BoringCrypto
|
||||
version, build a release, and upload it.
|
||||
|
||||
3. Run `build.docker`, which will build and upload a Docker image from the latest release.
|
||||
|
||||
4. Send out a CL with the updated `RELEASES` file and get it committed.
|
||||
|
||||
## Release process for dev.boringcrypto.go1.8.
|
||||
|
||||
In addition to the dev.boringcrypto branch, we have a dev.boringcrypto.go1.8 branch,
|
||||
which is BoringCrypto backported to the Go 1.8 release branch.
|
||||
To issue new BoringCrypto releases based on Go 1.8:
|
||||
|
||||
1. Do a regular release on the (not Go 1.8) dev.boringcrypto branch.
|
||||
|
||||
2. Change to the dev.boringcrypto.go1.8 branch and cherry-pick all
|
||||
BoringCrypto updates, including the update of the `VERSION` file.
|
||||
Mail them out and get them committed.
|
||||
|
||||
3. **Back on the (not Go 1.8) dev.boringcrypto branch**, run `build.release <commit>`,
|
||||
where `<commit>` is the latest commit on the dev.boringcrypto.go1.8 branch.
|
||||
It will build a release and upload it.
|
||||
|
||||
4. Run `build.docker`.
|
||||
|
||||
5. Send out a CL with the updated `RELEASES` file and get it committed.
|
||||
|
||||
## Building from Docker
|
||||
|
||||
A Dockerfile that starts with `FROM golang:1.8.3` can switch
|
||||
to `FROM goboring/golang:1.8.3b2` (see [goboring/golang on Docker Hub](https://hub.docker.com/r/goboring/golang/))
|
||||
and should need no other modifications.
|
||||
|
||||
## Building from Bazel
|
||||
|
||||
Using an alternate toolchain from Bazel is not as clean as it might be.
|
||||
Today, as of Bazel 0.5.3 and the bazelbuild/rules_go tag 0.5.3,
|
||||
it is necessary to define a `go-boringcrypto.bzl` file that duplicates
|
||||
some of the rules_go internal guts and then invoke its `go_repositories` rule
|
||||
instead of the standard one.
|
||||
|
||||
See https://gist.github.com/rsc/6f63d54886c9c50fa924597d7355bc93 for a minimal example.
|
||||
|
||||
Note that in the example that the Bazel `WORKSPACE` file still refers to the release as "go1.8.3" not "go1.8.3b2".
|
||||
|
||||
## Caveat
|
||||
|
||||
BoringCrypto is used for a given build only in limited circumstances:
|
||||
|
||||
- The build must be GOOS=linux, GOARCH=amd64.
|
||||
- The build must have cgo enabled.
|
||||
- The android build tag must not be specified.
|
||||
- The cmd_go_bootstrap build tag must not be specified.
|
||||
|
||||
The version string reported by `runtime.Version` does not indicate that BoringCrypto
|
||||
was actually used for the build. For example, linux/386 and non-cgo linux/amd64 binaries
|
||||
will report a version of `go1.8.3b2` but not be using BoringCrypto.
|
||||
|
||||
To check whether a given binary is using BoringCrypto, run `go tool nm` on it and check
|
||||
that it has symbols named `*_Cfunc__goboringcrypto_*`.
|
||||
|
||||
The program [rsc.io/goversion](https://godoc.org/rsc.io/goversion) will report the
|
||||
crypto implementation used by a given binary when invoked with the `-crypto` flag.

This script assumes that is is run from the root of your Go package (for
|
||||
example, "/go/src/app" if your GOPATH is set to "/go").
|
||||
|
||||
In Go 1.4, a feature was introduced to supply the canonical "import path" for a
|
||||
given package in a comment attached to a package statement
|
||||
(https://golang.org/s/go14customimport).
|
||||
|
||||
This script allows us to take a generic directory of Go source files such as
|
||||
"/go/src/app" and determine that the canonical "import path" of where that code
|
||||
expects to live and reference itself is "github.com/jsmith/my-cool-app". It
|
||||
will then ensure that "/go/src/github.com/jsmith/my-cool-app" is a symlink to
|
||||
"/go/src/app", which allows us to build and run it under the proper package
|
||||
name.
|
||||
|
||||
For compatibility with versions of Go older than 1.4, the "import path" may also
|
||||
be placed in a file named ".godir".
