At the moment, the git-fsck's integrity checks are targeted toward the
end user, i.e. the error messages are really just messages, intended for
human consumption.

Under certain circumstances, some of those errors should be allowed to
be turned into mere warnings, though, because the cost of fixing the
issues might well be larger than the cost of carrying those flawed
objects. For example, when an already-public repository contains a
commit object with two authors for years, it does not make sense to
force the maintainer to rewrite the history, affecting all contributors
negatively by forcing them to update.

This branch introduces an internal fsck API to be able to turn some of
the errors into warnings, and to make it easier to call the fsck
machinery from elsewhere in general.

I am proud to report that this work has been sponsored by GitHub.


Johannes Schindelin (18):
  Introduce fsck options
  Introduce identifiers for fsck messages
  Provide a function to parse fsck message IDs
  Offer a function to demote fsck errors to warnings
  Allow demoting errors to warnings via receive.fsck.<key> = warn
  fsck: report the ID of the error/warning
  Make fsck_ident() warn-friendly
  Make fsck_commit() warn-friendly
  fsck: handle multiple authors in commits specially
  Make fsck_tag() warn-friendly
  Add a simple test for receive.fsck.*
  Disallow demoting grave fsck errors to warnings
  Optionally ignore specific fsck issues completely
  fsck: allow upgrading fsck warnings to errors
  Document the new receive.fsck.* options.
  fsck: support demoting errors to warnings
  Introduce `git fsck --quick`
  git receive-pack: support excluding objects from fsck'ing
