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.

When importing from multiple perforce paths - we may attempt to
import a changelist that contains files from two (or more) of these
depot paths. Currently, this results in multiple git commits - one
containing the changes, and the other(s) as empty commit(s). This
behavior was introduced in commit 1f90a64891 ("git-p4: reduce number
of server queries for fetches", 2015-12-19).
Reproduction Steps:
1. Have a git repo cloned from a perforce repo using multiple
depot paths (e.g. //depot/foo and //depot/bar).
2. Submit a single change to the perforce repo that makes changes
in both //depot/foo and //depot/bar.
3. Run "git p4 sync" to sync the change from #2.
Change is synced as multiple commits, one for each depot path that
was affected.
Using a set, instead of a list inside p4ChangesForPaths() ensures
that each changelist is unique to the returned list, and therefore
only a single commit is generated for each changelist.

t0021.15 creates files, adds them to the index, and commits them. All
this usually happens in a test run within the same second and Git cannot
know if the files have been changed between `add` and `commit`. Thus,
Git has to run the clean filter in both operations. Sometimes these
invocations spread over two different seconds and Git can infer that the
files were not changed between `add` and `commit` based on their
modification timestamp. The test would fail as it expects the filter
invocation. Remove this expectation to make the test stable.

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() is not prepared to keep the double-slash of a

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

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.
Signed-off-by: Jeff King <peff@peff.net>
Signed-off-by: Junio C Hamano <gitster@pobox.com>
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.

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

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.
