from a revision, i.e. the former index_is_dirty() behavior can now be
achieved by index_differs_from("HEAD", 0).

The second argument "diff_flags" allows to set further diff option
flags like DIFF_OPT_IGNORE_SUBMODULES. See DIFF_OPT_* macros in diff.h
for a list.

index_differs_from() seems to be useful for more than builtin-revert.c,
so it is moved into diff-lib.c and also used in builtin-commit.c.

Yet to mention:

 - "rev.abbrev = 0;" can be safely removed.
   This has no impact on performance or functioning of neither
   setup_revisions() nor run_diff_index().

 - rev.pending.objects is free()d because this fixes a leak.

relative one (e.g. share/git-core/templates) but it was done by checking
if $(abspath $(template_dir)) and $(template_dir) yield the same string.

This was wrong in at least two ways.

 * The user can give template_dir with a trailing slash from the command
   line to invoke make or from the included config.mak.  A directory path
   ought to mean the same thing with or without such a trailing slash but
   use of $(abspath) means an absolute path with a trailing slash fails
   the test.

 * Versions of GNU make older than 3.81 do not have $(abspath) to begin

builtin-remote: make rm operation safer in mirrored repository

"git remote rm <repo>" happily removes non-remote refs and their reflogs.
This may be okay if the repository truely is a mirror, but if the user
had done "git remote add --mirror <repo>" by accident and was just
undoing their mistake, then they are left in a situation that is
difficult to recover from.

After this commit, "git remote rm" skips over non-remote refs. The user
is advised on how remove branches using "git branch -d", which itself
has nice safety checks wrt to branch removal lacking from "git remote rm".
Non-remote non-branch refs are skipped silently.

15 years agofilter-branch: Fix fatal error on bare repositories
Eric Kidd [Tue, 3 Feb 2009 18:27:03 +0000 (13:27 -0500)]
filter-branch: Fix fatal error on bare repositories

When git filter-branch is run on a bare repository, it prints out a fatal
error message:

  $ git filter-branch branch
  Rewrite 476c4839280c219c2317376b661d9d95c1727fc3 (9/9)
  WARNING: Ref 'refs/heads/branch' is unchanged
  fatal: This operation must be run in a work tree

Note that this fatal error message doesn't prevent git filter-branch from
exiting successfully. (Why doesn't git filter-branch actually exit with an
error when a shell command fails? I'm not sure why it was designed this
way.)

This error message is caused by the following section of code at the end of
git-filter-branch.sh:

  if [ "$(is_bare_repository)" = false ]; then
          unset GIT_DIR GIT_WORK_TREE GIT_INDEX_FILE
          test -z "$ORIG_GIT_DIR" || {
                  GIT_DIR="$ORIG_GIT_DIR" && export GIT_DIR
          }
          ... elided ...
          git read-tree -u -m HEAD
  fi

The problem is the call to $(is_bare_repository), which is made before
GIT_DIR and GIT_WORK_TREE are restored.  This call always returns "false",
even when we're running in a bare repository.  But this means that we will
attempt to call 'git read-tree' even in a bare repository, which will fail
and print an error.

This patch modifies git-filter-branch.sh to restore the original
environment variables before trying to call is_bare_repository.
