When read, a commit_graft will be constructed, which has nr_parent < 0 to make it easier to discern from user provided grafts. +Note that the shallow feature could not be changed easily to +use replace refs: a commit containing a `mergetag` is not allowed +to be replaced, not even by a root commit. Such a commit can be +made shallow, though. Also, having a `shallow` file explicitly +listing all the commits made shallow makes it a *lot* easier to +do shallow-specific things such as to deepen the history. + Since fsck-objects relies on the library to read the objects, it honours shallow commits automatically. |
