|
9 | 9 | This extension provides a ``phabsend`` command which sends a stack of |
|
10 | 10 | changesets to Phabricator without amending commit messages, and a ``phabread`` |
|
11 | 11 | command which prints a stack of revisions in a format suitable |
|
12 | 12 | for :hg:`import`. |
|
13 | 13 | |
|
14 | 14 | By default, Phabricator requires ``Test Plan`` which might prevent some |
|
15 | 15 | changeset from being sent. The requirement could be disabled by changing |
|
16 | 16 | ``differential.require-test-plan-field`` config server side. |
