mailinfo.c: move side-effects outside of assertKyle J. McKay Mon, 19 Dec 2016 23:13:00 +0000 (15:13 -0800)

mailinfo.c: move side-effects outside of assert

Since 6b4b013f18 (mailinfo: handle in-body header continuations,
2016-09-20, v2.11.0) mailinfo.c has contained new code with an
assert of the form:

assert(call_a_function(...))

The function in question, check_header, has side effects. This
means that when NDEBUG is defined during a release build the
function call is omitted entirely, the side effects do not
take place and tests (fortunately) start failing.

Since the only time that mi->inbody_header_accum is appended to is
in check_inbody_header, and appending onto a blank
mi->inbody_header_accum always happens when is_inbody_header is
true, this guarantees a prefix that causes check_header to always
return true.

Therefore replace the assert with an if !check_header + DIE
combination to reflect this.

index-pack: skip collision check when not in repository

You can run "git index-pack path/to/foo.pack" outside of a
repository to generate an index file, or just to verify the
contents. There's no point in doing a collision check, since
we obviously do not have any objects to collide with.

The current code will blindly look in .git/objects based on
the result of setup_git_env(). That effectively gives us the
right answer (since we won't find any objects), but it's a
waste of time, and it conflicts with our desire to
eventually get rid of the "fallback to .git" behavior of
setup_git_env().

normalize_path_copy(): fix pushing to //server/share... Johannes Sixt Wed, 14 Dec 2016 19:37:38 +0000 (20:37 +0100)

normalize_path_copy(): fix pushing to //server/share/dir on Windows

normalize_path_copy() is not prepared to keep the double-slash of a
//server/share/dir kind of path, but treats it like a regular POSIX
style path and transforms it to /server/share/dir.

The bug manifests when 'git push //server/share/dir master' is run,
because tmp_objdir_add_as_alternate() uses the path in normalized
form when it registers the quarantine object database via
link_alt_odb_entries(). Needless to say that the directory cannot be
accessed using the wrongly normalized path.

Fix it by skipping all of the root part, not just a potential drive
prefix. offset_1st_component takes care of this, see the
implementation in compat/mingw.c::mingw_offset_1st_component().

t: use nongit() function where applicable

Many tests want to run a command outside of any git repo;
with the nongit() function this is now a one-liner. It saves
a few lines, but more importantly, it's immediately obvious
what the code is trying to accomplish.

This doesn't convert every such case in the test suite; it
just covers those that want to do a one-off command. Other
cases, such as the ones in t4035, are part of a larger
scheme of outside-repo files, and it's less confusing for
them to stay consistent with the surrounding tests.

The index-pack builtin is marked as RUN_SETUP_GENTLY,

filesystem outside of any repository. However, --stdin mode
will write the result to the object database, which does not
make sense outside of a repository. Doing so creates a bogus

pack and its index.

To perform the test case on Windows in a way that corresponds to the

Typically, an absolute POSIX style path, such as the one in $PWD, is
translated into a Windows style path by bash when it invokes git.exe.
However, the presence of the semicolon suppresses this translation;
but the untranslated POSIX style path is useless for git.exe.
Therefore, instead of $PWD pass the Windows style path that $(pwd)

tmp-objdir: quote paths we add to alternatesJeff King Mon, 12 Dec 2016 19:53:55 +0000 (14:53 -0500)

tmp-objdir: quote paths we add to alternates

Commit 722ff7f87 (receive-pack: quarantine objects until
pre-receive accepts, 2016-10-03) regressed pushes to
repositories with colon (or semi-colon in Windows in them)
because it adds the repository's main object directory to
GIT_ALTERNATE_OBJECT_DIRECTORIES. The receiver interprets
the colon as a delimiter, not as part of the path, and
index-pack is unable to find objects which it needs to
resolve deltas.

The previous commit introduced a quoting mechanism for the
alternates list; let's use it here to cover this case. We'll
avoid quoting when we can, though. This alternate setup is
also used when calling hooks, so it's possible that the user
may call older git implementations which don't understand
the quoting mechanism. By quoting only when necessary, this
setup will continue to work unless the user _also_ has a
repository whose path contains the delimiter.

alternates: accept double-quoted pathsJeff King Mon, 12 Dec 2016 19:52:22 +0000 (14:52 -0500)

alternates: accept double-quoted paths

We read lists of alternates from objects/info/alternates
files (delimited by newline), as well as from the
GIT_ALTERNATE_OBJECT_DIRECTORIES environment variable
(delimited by colon or semi-colon, depending on the
platform).

There's no mechanism for quoting the delimiters, so it's
impossible to specify an alternate path that contains a
colon in the environment, or one that contains a newline in
a file. We've lived with that restriction for ages because
both alternates and filenames with colons are relatively
rare, and it's only a problem when the two meet. But since
722ff7f87 (receive-pack: quarantine objects until
pre-receive accepts, 2016-10-03), which builds on the
alternates system, every push causes the receiver to set
GIT_ALTERNATE_OBJECT_DIRECTORIES internally.

It would be convenient to have some way to quote the
delimiter so that we can represent arbitrary paths.

The simplest thing would be an escape character before a
quoted delimiter (e.g., "\:" as a literal colon). But that
creates a backwards compatibility problem: any path which
uses that escape character is now broken, and we've just
shifted the problem. We could choose an unlikely escape
character (e.g., something from the non-printable ASCII
range), but that's awkward to use.

Instead, let's treat names as unquoted unless they begin
with a double-quote, in which case they are interpreted via
our usual C-stylke quoting rules. This also breaks
backwards-compatibility, but in a smaller way: it only
matters if your file has a double-quote as the very _first_
character in the path (whereas an escape character is a
problem anywhere in the path). It's also consistent with
many other parts of git, which accept either a bare pathname
or a double-quoted one, and the sender can choose to quote
or not as required.

mingw: intercept isatty() to handle /dev/null as Git expects it

When Git's source code calls isatty(), it really asks whether the
respective file descriptor is connected to an interactive terminal.

Windows' _isatty() function, however, determines whether the file
descriptor is associated with a character device. And NUL, Windows'
equivalent of /dev/null, is a character device.

Which means that for years, Git mistakenly detected an associated
interactive terminal when being run through the test suite, which
almost always redirects stdin, stdout and stderr to /dev/null.

This bug only became obvious, and painfully so, when the new
bisect--helper entered the `pu` branch and made the automatic build & test
time out because t6030 was waiting for an answer.

rebase: add --quit to cleanup rebase, leave everything else untouched

There are occasions when you decide to abort an in-progress rebase and
move on to do something else but you forget to do "git rebase --abort"
first. Or the rebase has been in progress for so long you forgot about
it. By the time you realize that (e.g. by starting another rebase)
it's already too late to retrace your steps. The solution is normally

rm -r .git/<some rebase dir>

and continue with your life. But there could be two different
directories for <some rebase dir> (and it obviously requires some
knowledge of how rebase works), and the ".git" part could be much
longer if you are not at top-dir, or in a linked worktree. And
"rm -r" is very dangerous to do in .git, a mistake in there could
destroy object database or other important data.

Provide "git rebase --quit" for this use case, mimicking a precedent
that is "git cherry-pick --quit".

sequencer: remove useless get_dir() function

This function is used only once, for the removal of the

sequencer: make sequencer abort safer

In contrast to "git am --abort", a sequencer abort did not check
whether the current HEAD is the one that is expected. This can lead
to loss of work (when not spotted and resolved using reflog before
the garbage collector chimes in).

This behavior is now changed by mimicking "git am --abort". The
abortion is done but HEAD is not changed when the current HEAD is
not the expected HEAD.

A new file "sequencer/abort-safety" is added to save the expected
HEAD.

The new behavior is only active when --abort is invoked on multiple
picks. The problem does not occur for the single-pick case because
it is handled differently.

The behavior is now documented; more importantly, rewarding the user
with a "Wow, you are clever" praise afterwards is not an effective
way to advertise the feature--at that point the user already knows.

diff: handle --no-abbrev in no-index caseJack Bates Tue, 6 Dec 2016 16:56:14 +0000 (09:56 -0700)

diff: handle --no-abbrev in no-index case

There are two different places where the --no-abbrev option is parsed,
and two different places where SHA-1s are abbreviated. We normally parse
--no-abbrev with setup_revisions(), but in the no-index case, "git diff"
calls diff_opt_parse() directly, and diff_opt_parse() didn't handle
--no-abbrev until now. (It did handle --abbrev, however.) We normally
abbreviate SHA-1s with find_unique_abbrev(), but commit 4f03666 ("diff:
handle sha1 abbreviations outside of repository, 2016-10-20) recently
introduced a special case when you run "git diff" outside of a
repository.

setup_revisions() does also call diff_opt_parse(), but not for --abbrev
or --no-abbrev, which it handles itself. setup_revisions() sets
rev_info->abbrev, and later copies that to diff_options->abbrev. It
handles --no-abbrev by setting abbrev to zero. (This change doesn't
touch that.)

Setting abbrev to zero was broken in the outside-of-a-repository special
case, which until now resulted in a truly zero-length SHA-1, rather than
taking zero to mean do not abbreviate. The only way to trigger this bug,
however, was by running "git diff --raw" without either the --abbrev or
--no-abbrev options, because 1) without --raw it doesn't respect abbrev
(which is bizarre, but has been that way forever), 2) we silently clamp
--abbrev=0 to MINIMUM_ABBREV, and 3) --no-abbrev wasn't handled until
now.

The outside-of-a-repository case is one of three no-index cases. The
other two are when one of the files you're comparing is outside of the
repository you're in, and the --no-index option.

difftool: fix dir-diff index creation when in a subdire... David Aguilar Wed, 7 Dec 2016 10:16:08 +0000 (02:16 -0800)

difftool: fix dir-diff index creation when in a subdirectory

9ec26e7977 (difftool: fix argument handling in subdirs, 2016-07-18)
corrected how path arguments are handled in a subdirectory, but
it introduced a regression in how entries outside of the
subdirectory are handled by dir-diff.

When preparing the right-side of the diff we only include the
changed paths in the temporary area.

The left side of the diff is constructed from a temporary
index that is built from the same set of changed files, but it
was being constructed from within the subdirectory. This is a
problem because the indexed paths are toplevel-relative, and
thus they were not getting added to the index.

Teach difftool to chdir to the toplevel of the repository before
preparing its temporary indexes. This ensures that all of the
toplevel-relative paths are valid.

Add test cases to more thoroughly exercise this scenario.

am: change safe_to_abort()'s not rewinding error into a warning

The error message tells the user that something went terribly wrong
and the --abort could not be performed. But the --abort is performed,
only without rewinding. By simply changing the error into a warning,
we indicate the user that she must not try something like
"git am --abort --force", instead she just has to check the HEAD.
