Pull request followup
=====================

Once a patch has been submitted gerrit can be used to track progress.

Find your patch
---------------

| Begin by viewing the history for your patch in gerrit.
| A patch can be accessed in a few different ways.

Item of Note:

- A Gerrit Change-Id is required to interact with a patch. This hashed
  value will be distinct from the underlying git checksum used when
  changes are stored in a repository.

Capture commit message output
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Gerrit commit hash and a URL are readily available in output.

git log can be used to search for them.

  - View all open/unmerged patches
  - Scroll down through the list until something of interest is found.
  - Under the # column (2nd column on left hand side) right click and open to view the patch.

Patch history and jenkins jobs
------------------------------

While viewing a patch (`repo:voltha-system-tests <https://gerrit.opencord.org/c/voltha-system-tests/+/33380>`_)
scroll down to the 'Change Log' section at the bottom.
| Line items represent historical comments, code review messages and
processed job status.

Entries prefixed with ``Jenkins Technical User`` contain jenkins job
information.  Jenkins pipeline jobs are constructed by performing
several atomic tasks each of which will generate a log with status.

To view job logs click on an entry to expand (Verified +1, 4th entry from
the bottom) to view a set of clickable jenkins URLs.
