Internal SRU team docs

Decision making

• Act for the team if you’re confident that the team would concur

• If unsure, ask, and if you need to follow up, add to the SRU team meeting agenda where we can make a team decision

Reviewing procedure and tools

If you are a member of the SRU reviewing team, you should check out the ubuntu-archive-tools scripts with

• git clone https://git.launchpad.net/ubuntu-archive-tools

which greatly simplifies the reviewing procedure. You should symlink sru-review and sru-accept somewhere to your ~/bin/ directory for easy access, or put the checkout into your $PATH.

The following review procedure is recommended:

• Open the unapproved queue for a particular release, e. g. https://launchpad.net/ubuntu/noble/+queue?queue_state=1 for noble. This shows the list of SRU uploads which have to be reviewed, commented on, and approved/accepted/rejected.

• For each package, generate the debdiff to the current version in the archive and open the corresponding bugs: sru-review -s noble gnash This opens all the bugs which are mentioned in the .changes file in the browser, and will generate a debdiff between the current archive and the unapproved upload (unless the orig.tar.gz changes this will only download the two diff.gz, so it is reasonably fast).

  • In case the SRU is a package sync instead of a standard upload, the sru-review tool will not be able to fetch the debdiff for you and will exit with an error. You will have to review the changes manually and then re-run the tool with an additional argument of –no-diff.

  • For Bileto published SRU’s you can easily fetch the relevant debdiffs by following the link to the sync’s source PPA and opening the ticket URL that’s provided in the PPA description. Each upload present there has two diffs generated for review convenience: full and packaging-only.

• Review the bugs for complete description, justification, check that they have a stable release task, are conformant to SRU rules, etc, and comment accordingly.

• Scrutinize the debdiff for matching the changes in the bugs, not having unrelated changes, etc. If you have doubts, comment on the bug.

• If you are in the ubuntu-sru team:

  • Exit the tool you are using to review the debdiff

  • If the bugs and debdiff are okay, accept the package by pressing y at the “”Accept the package into -proposed?” prompt. This will tag the bug(s) with verification-needed, verification-needed-$RELEASE, subscribe ubuntu-sru, and add a general “please test and give feedback”-like comment.

  • If the upload is broken or unsuitable for an SRU, reject it by pressing N at the “”Accept the package into -proposed?” prompt and pressing y at the “REJECT the package from -proposed?” prompt.

• If you are not in the ubuntu-sru team: Send a follow up comment to the bugs:

  • If all is okay: send an “ubuntu-sru approved and reviewed” comment and set the task to “In Progress”

  • If something is wrong: send the feedback to the bug and set the task to “Incomplete”

The pending SRUs should also be reviewed to see whether or not there are any to be released or removed from the archive. The process for dealing with these follows:

Packages in -proposed can be moved to -updates once they are approved by someone from sru-verification, and have passed the minimum aging period of 7 days. Use the sru-release script from ubuntu-archive-tools for this:

• $ ./sru-release noble kdebase

Please see –help, you can also use this tool to copy packages to -security and to the current development release. N.B. before copying a package to -security ping a member of the ubuntu-security team.

• Currently pending SRUs

If a package should be removed from -proposed, use the remove-package tool (from ubuntu-archive-tools). e.g., to remove source and binaries for the libreoffice package currently in xenial-proposed:

• $ ./remove-package -m “SRU abandoned (verification-failed)” -s noble-proposed libreoffice

Override phasing

Overriding phasing can only be performed by a member of the SRU team.

Overriding halted phasing is done in a similar way to overriding autopkgtest failures. The phased update machinery looks at phased-update-overrides.txt, which is a simple CSV file containing lines of the form source package, version, :math:`THING_TO_IGNORE where `THING_TO_IGNORE can either be an errors.ubuntu.com problem URL to ignore or increased-rate.

Adding members to the team

• Existing SRU team members identify when new team members are needed. They will privately nominate suitable candidates, with regard to their availability (eg. a discussion with their manager may be required).

• One existing team member will study a candidate’s recent SRU activity, assess them against our criteria and write a summary.

• The team will then decide whether the candidate is suitable.

• One existing team member will onboard a given new trainee, “sponsoring” privileged SRU actions such as review accept and release.

• This mentor will consult with other existing team members and the trainee will be given equivalent privileges when appropriate.

Criteria for new SRU team members

Hard requirements

• Must be able to upload all SRUs they expect to review; ie. Ubuntu Core Developer or SRU Developer. A member of the SRU team who is an SRU Developer is expected to be in the process of applying to be an Ubuntu Core Developer: the role involves exercising judgement about whether a change in the development series is good, and therefore someone in this role should be formally trusted by the project to make such decisions for the development series as well.

• Recent track record of good quality SRUs.

• Recent uploads (whether sponsored or not) either met our expectations or successfully anticipated concerns that could reasonably have been predicted by existing SRU team members.

• Few recent poor quality SRUs (nice to have: none). This includes uploads for issues that are unsuitable for SRU, as well as missing SRU information, missing bug references, poorly completed SRU information, etc. Exception: if an omission or concern is called out by the uploader and the upload was for the purpose of asking the SRU team about it.

• Can they say no?

Nice to haves

• Demonstrated familiarity across existing SRU policies and procedures (rather than just having correctly submitted good SRUs that might be limited in parts of SRU policy and procedure that they exercise)

• What about SRUs they’ve sponsored: do they successfully raise the quality of SRU submissions to our expected level before they sponsor them? If so, then this might be a good indicator that they’ll be able to do similar at SRU review time.

• Do they have a track record of spotting issues before they occur? How broadly do they look when determining “Where problems could occur”? Do they then make sure the Test Plan covers identified risks?

• Do they seek to change general policy when appropriate, rather than ignoring it? Can they identify the difference between individual exceptions and the general case?
