When contributing to this repository, please feel free to first start a discussion either via issue or our mailing list [email protected] before working on the change.
- Ensure all tests pass on your forked branch prior to submitting the PR; if necessary add words flagged by the 01-spellcheck.sh test to the dictionary
- All pull requests should be made against the develop branch
- Update the help and man pages with any additional functionality being added by the PR; try to do this in independent commits to make reviewing easier
- Update the file list in 01-spellcheck.sh if adding a new documentation file
- Don't bump version numbers - this will be done during a release
We adhere to Google's shell style guide. One of the current exceptions is to declare all variables in capitals, not just global variables.
For all changes, the following should be considered the bare minimum to be tested:
auter --disable # deletes /var/lib/auter/enabled, prints "auter disabled"
auter --status # prints "auter is currently disabled"
auter --enable # touches /var/lib/auter/enabled, prints "auter enabled"
auter --status # prints "auter is currently enabled and not running"
auter --help # shows help message
auter --version # prints "auter VERSIONNUMBER"
man auter # check the contents of the man page reflect the relevant changes
man auter.conf # if relevant, check the contents of the man page reflect the changesIf no updates are available, try downgrading a package like openssl or curl which often has several versions available.
RHEL based distributions:
$ yum --showduplicates list curl
$ yum downgrade curl libcurlDebian based distributions:
# This will give you a list of packages that have multiple versions available in the repos:
for PKG in $(dpkg --list | awk '{print $2}'); do
VERSIONS="$(apt-cache showpkg $PKG | awk '/Versions:/,/^Reverse Depends:/ {if ($1 ~ /^[0-9]/) print $1}' | xargs)"
[[ $(echo ${VERSIONS} | wc -w) -gt 1 ]] && echo "$PKG -% $VERSIONS"
done | column -t -s "%"
$ apt-get update
$ apt-get install <PACKAGE>=<VERSION>Note: You may need to also downgrade dependencies.
Use the following to setup the pre/post scripts:
echo 'logger custom pre prep script ran' > /etc/auter/pre-prep.d/pre_prep_script
echo 'logger custom post prep script ran' > /etc/auter/post-prep.d/post_prep_script
echo 'logger custom pre apply script ran' > /etc/auter/pre-apply.d/pre_apply_script
echo 'logger custom post apply script ran' > /etc/auter/post-apply.d/post_apply_script
echo 'logger custom pre reboot script ran' > /etc/auter/pre-reboot.d/pre_reboot_script
echo 'logger custom post reboot script ran' > /etc/auter/post-reboot.d/post_reboot_script
chmod +x /etc/auter/*.d/*script- Run the base commands directly via command line testing for both positive and negative outcomes
- Run the base commands via
atjob, again testing both positive and negative outcomes - Test the effects of the change in the function. Again, if possible, test success and failure conditions
- Test all functionality in Auter that is affected by the code changes.
- A new issue should be raised with the title of "Prep for Release"
- Ensure all required pull requests for the new release have been merged to the develop branch
- A maintainer with admin rights to the master branch in rackerlabs/auter should create a new branch based from the develop branch:
git clone --branch=develop https://github.com/rackerlabs/auter.git rackerlabs/auter
cd rackerlabs/auter
git checkout -b Release-<NEW_VERSION>
git push origin Release-<NEW_VERSION>- Any new pull requests should be made to the develop branch. The only changes to the Release-<NEW_VERSION> should be fixing of any review issues for that branch.
- Full testing for all supported distributions should be carried out and tracked in a github project created for the release. Example: https://github.com/rackerlabs/auter/projects/1
- Once all testing has been completed for Release-<NEW_VERSION>, the reviewer should merge the Release-<NEW_VERSION> branch to both master and develop branches.
- Tag a new release named <NEW_VERSION> using template <major_version>.<minor_version> (Eg: Release 0.11)
This should be completed for all supported distributions in all pull requests to the master branch before being merged.
