- A Go environment with a recent 64-bit version of the toolchain. Note that

the Makefile enforces the specific version required, as it is updated

frequently.

- XZ Utils (5.2.3+ is known to work), except on macOS, where xz support is
16
built in to `tar`.

- Optional: NodeJS 6.x and Yarn 0.22.0+. Required when compiling protocol

buffers.

version excluding enterprise functionality, use `make buildoss`. See this

When you're ready to commit, be sure to write a Good Commit Message™. Consult
103
https://github.com/erlang/otp/wiki/Writing-good-commit-messages if you're
104
not sure what constitutes a Good Commit Message™.
105
In addition to the general rules referenced above, please also prefix your
106
commit subject line with the affected package, if one can easily be chosen.
107
For example, the subject line of a commit mostly affecting the
108
`server/serverpb` package might read: "server/serverpb: made great again".
109
Commits which affect many packages as a result of a shared dependency change
110
should probably begin their subjects with the name of the shared dependency.
111
Finally, some commits may need to affect many packages in a way which does
112
not point to a specific package; those commits may begin with "*:" or "all:"
113
to indicate their reach.

123
+ When you’re ready for review, groom your work: each commit should pass tests
124
and contain a substantial (but not overwhelming) unit of work. You may also

want to `git fetch origin` and run

+ Then [create a pull request using GitHub’s UI](https://help.github.com/articles/creating-a-pull-request). If you know of
133
another GitHub user particularly suited to reviewing your pull request, be
134
sure to mention them in the pull request body. If you possess the necessary
135
GitHub privileges, please also [assign them to the pull request using
136
GitHub's UI](https://help.github.com/articles/assigning-issues-and-pull-requests-to-other-github-users/).
139
+ If you get a test failure in CircleCI, check the Test Failure tab to see why
140
the test failed. When the failure is logged in `excerpt.txt`, you can find
141
the file from the Artifacts tab and see log messages. (You need to sign in to

+ Address feedback by amending your commits. If your change contains multiple
145
commits, address each piece of feedback by amending that commit to which the
146
particular feedback is aimed. Wait (or ask) for new feedback on those
147
commits if they are not straightforward. An `LGTM` ("looks good to me") by
148
someone qualified is usually posted when you're free to go ahead and merge.
