8c24d832cd verify_pack: do not ignore return value of verification function
In verify_pack, a caller-supplied verification function is called.
The function returns an int.  If that return value is non-zero,
verify_pack should fail.

The only caller of verify_pack is in builtin/fsck.c, whose verify_fn
returns a meaningful error code (which was then ignored).  Now, fsck
might return a different error code (with more detail).  This would
happen in the unlikely event that a commit or tree that is a valid git
object but not a valid instance of its type gets into a pack.

08a3651fe7 Make error message after failing commit_lock_file() less confusing
The error message after a failing commit_lock_file() call sometimes
looks like this, causing confusion:

  $ git remote add remote git@server.com/repo.git
  error: could not commit config file .git/config
  # Huh?!
  # I didn't want to commit anything, especially not my config file!

While in the narrow context of the lockfile module using the verb
'commit' in the error message makes perfect sense, in the broader
context of git the word 'commit' already has a very specific meaning,
hence the confusion.

Reword these error messages to say "could not write" instead of "could
not commit".

While at it, include strerror in the error messages after writing the
config file or the credential store fails to provide some information
about the cause of the failure, and update the style of the error
message after writing the reflog fails to match surrounding error
messages (i.e. no '' around the pathname and no () around the error
description).

And if a branch is named "H", "HE", or "HEA" then the current if clause
erroneously considers it as matching "HEAD" because it only compares
up to the end of the branch name.

Fix that by doing the comparison using strcmp() and only after the
branch name is extracted.  This way neither too less nor too many
characters are checked.  While at it call strchrnul() to find the end
of the branch name instead of open-coding it.

8bf4becf0c add "ok=sigpipe" to test_must_fail and use it to fix flaky tests
t5516 "75 - deny fetch unreachable SHA1, allowtipsha1inwant=true" is
flaky in the following case:
1. remote upload-pack finds out "not our ref"
2. remote sends a response and closes the pipe
3. fetch-pack still tries to write commands to the remote upload-pack
4. write call in wrapper.c dies with SIGPIPE

The test is flaky because the sending fetch-pack may or may
not have finished writing its output by step (3). If it did,
then we see a closed pipe on the next read() call. If it
didn't, then we get the SIGPIPE from step (4) above. Both
are fine, but the latter fools test_must_fail.

t5504 "9 - push with transfer.fsckobjects" is flaky, too, and returns
SIGPIPE once in a while. I had to remove the final "To dst..." output
check because there is no output if the process dies with SIGPIPE.

Accept such a death-with-sigpipe also as OK when we are expecting a
failure.

4d2a3646d1 filter-branch: deal with object name vs. pathname ambiguity in tree-filter
'git filter-branch' fails complaining about an ambiguous argument, if
a tree-filter renames a path and the new pathname happens to match an
existing object name.

After the tree-filter has been applied, 'git filter-branch' looks for
changed paths by running:

  git diff-index -r --name-only --ignore-submodules $commit

which then, because of the lack of disambiguating double-dash, can't
decide whether to treat '$commit' as revision or path and errors out.

Add that disambiguating double-dash after 'git diff-index's revision
argument to make sure that '$commit' is interpreted as a revision.

7cb5f7c44d blame: fix object casting regression
Commit 1b0d400 refactored the prepare_final() function so
that it could be reused in multiple places. Originally, the
loop had two outputs: a commit to stuff into sb->final, and
the name of the commit from the rev->pending array.

After the refactor, that loop is put in its own function
with a single return value: the object_array_entry from the
rev->pending array. This contains both the name and the object,
but with one important difference: the object is the
_original_ object found by the revision parser, not the
dereferenced commit. If one feeds a tag to "git blame", we
end up casting the tag object to a "struct commit", which
causes a segfault.

Instead, let's return the commit (properly casted) directly
from the function, and take the "name" as an optional
out-parameter. This does the right thing, and actually
simplifies the callers, who no longer need to cast or
dereference the object_array_entry themselves.

c26f70ceb3 bash prompt: indicate dirty index even on orphan branches
__git_ps1() doesn't indicate dirty index while on an orphan branch.

To check the dirtiness of the index, __git_ps1() runs 'git diff-index
--cached ... HEAD', which doesn't work on an orphan branch,
because HEAD doesn't point to a valid commit.

Run 'git diff ... --cached' instead, as it does the right thing both
on valid and invalid HEAD, i.e. compares the index to the existing
HEAD in the former case and to the empty tree in the latter.  This
fixes the two failing tests added in the first commit of this series.

The dirtiness of the worktree is already checked with 'git diff' and
is displayed correctly even on an orphan branch.

There is only a single test exercising the dirty state indicator on an
orphan branch, and in that test neither the index nor the worktree are
dirty.

Add two failing tests to check the dirty state indicator while either
the index is dirty or while both the index and the worktree are dirty
on an orphan branch, and to show that the dirtiness of the index is
not displayed in these cases (the fourth combination, i.e. clean index
and dirty worktree are impossible on an orphan branch).  Update the
existing dirty state indicator on clean orphan branch test to match
the style of the two new tests, most importantly to use 'git checkout

b33a15b081 push: add recurseSubmodules config option
The --recurse-submodules command line parameter has existed for some
time but it has no config file equivalent.

Following the style of the corresponding parameter for git fetch, let's
invent push.recurseSubmodules to provide a default for this
parameter. This also requires the addition of --recurse-submodules=no to
allow the configuration to be overridden on the command line when
required.

The most straightforward way to implement this appears to be to make
push use code in submodule-config in a similar way to fetch.

7f4d4746c1 credential-cache: new option to ignore sighup
Introduce new option "credentialCache.ignoreSIGHUP" which stops
git-credential-cache--daemon from quitting on SIGHUP.  This is useful
when "git push" is started from Emacs, because all child
processes (including the daemon) will receive a SIGHUP when "git push"
exits.

42fdf86e5f show-ref: stop using PARSE_OPT_NO_INTERNAL_HELP
The flag PARSE_OPT_NO_INTERNAL_HELP is set to allow overriding the
option -h, except when it's the only one given.  This is the default
behavior now, so remove the flag and the hand-rolled --help-all
handling.  The internal --help-all handler now actually shows hidden
options, i.e. -h in this case.

8a272f291a fsck: treat a NUL in a tag header as an error
We check the return value of verify_header() for commits already, so do
the same for tags as well.

5ad0d3d526 parse-options: allow -h as a short option
Let callers provide their own handler for the short option -h even
without the flag PARSE_OPT_NO_INTERNAL_HELP, but call the internal
handler (showing usage information) if that is the only parameter.
Implement the first part by checking for -h only if parse_short_opt()
can't find it and returns -2.
