t2300: "git --exec-path" is not usable in $PATH on Windows as-is
The "git" command prepends the exec-path to the PATH environment
variable for processes it spawns. That is how ". git-sh-setup" in
our scripted Porcelains can find the dot-sourced file in the
exec-path location that is not usually on user's PATH.
When t2300 runs, because it is not spawned by the "git" command, the
scriptlet being tested did not run with a realistic setting of PATH
environment. It lacked the exec-path on the PATH, and failed to
find the dot-sourced file. A recent update to t2300 attempted to
fix this, with "PATH=$(git --exec-path):$PATH", which has been the
recommended way around v1.6.0 days (a script whose original was
written before that release that survives to this day is likely to
have such a line).
However, the "git --exec-path" command outputs C:\path\to\exec\dir
(not /c/path/to/exec/dir) on Windows; the recent update failed to
consider the problem that comes from it.
Even though Git itself, when doing the equivalent internally, does
so in a platform native way (i.e. on Windows, C:\path\to\exec\dir is
prepended to the existing value of %PATH% using ';' as a component
separator), the result is further massaged by bash and gets turned
into $PATH that uses /c/path/to/exec/dir with ':' separating the
components, which is the form understood by bash, so scripted
Porcelains find commands from PATH correctly.
An end user script written in shell, however, cannot prepend
"C:\path\to\exec\dir:" to the existing value of $PATH and expect
bash to magically turn it into the form it understands. In other
words, "PATH=$(git --exec-path):$PATH" does not work as an emulation
of what "Git" internally does to the PATH on Windows.
To correctly emulate how exec-path is prepended to the PATH
environment internally on Windows, we'd need to convert
C:\git-sdk-64\usr\src\git to at least /c\git-sdk-64\usr\src\git
ourselves before prepending it to PATH.

As this developer has no access to MacOSX developer setups anymore,

When we want to know the local timezone offset at a given
timestamp, we compute it by asking for localtime() at the
given time, and comparing the offset to GMT at that time.
However, there's some juggling between time_t and "struct
tm" which happens, which involves calling our own
tm_to_time_t().
If that function returns an error (e.g., because it only
handles dates up to the year 2099), it returns "-1", which
we treat as a time_t, and is clearly bogus, leading to
bizarre timestamps (that seem to always adjust the time back
to (time_t)(uint32_t)-1, in the year 2106).
It's not a good idea for local_tzoffset() to simply die
here; it would make it hard to run "git log" on a repository
with funny timestamps. Instead, let's just treat such cases
as "zero offset".

clone: do not let --depth imply --shallow-submodules

sh-setup: enclose setting of ${VAR=default} in double-quotes
We often make sure an environment variable is set to
something, either set by the user (in which case we do not
molest it) or set it to our default value (otherwise), with
: ${VAR=default value}
i.e. running the no-op command ":" with ${VAR} as its
parameters (or the default value we supply), relying on that
":" is a no-op.
This pattern, even though it is no-op from correctness point
of view, still can be expensive if the existing value in VAR
has shell glob (because they will be expanded against
filesystem entities) and IFS whitespaces (because the value
need to be split into multiple parameters). Our invocation
of ":" command does not care if the parameter given to it is
after the value in VAR goes through these processing.
Enclosing the whole thing in double-quote, i.e.
: "${VAR=default value}"
avoids paying the unnecessary cost, so let's do so.

bisect: always call setup_revisions after init_revisions
init_revisions() initializes the rev_info struct to default
values, and setup_revisions() parses any command-line
arguments and finalizes the struct.
In e22278c (bisect: display first bad commit without forking
a new process, 2009-05-28), a show_diff_tree() was added
that calls the former but not the latter. It doesn't have
any arguments to parse, but it still should do the
finalizing step.
This may have caused other minor bugs over the years, but it
became much more prominent after fe37a9c (pretty: allow
tweaking tabwidth in --expand-tabs, 2016-03-29). That leaves
the expected tab width as "-1", rather than the true default
of "8". When we see a commit with tabs to be expanded, we
end up trying to add (size_t)-1 spaces to a strbuf, which
complains about the integer overflow.

Commit 72441af (tree-diff: rework diff_tree() to generate
diffs for multiparent cases as well, 2014-04-07) introduced
the use of alloca so that the common cases of commits with 1
or 2 parents would not be adversely affected by going
through the multi-parent code.
However, our xalloca is not ideal when the number of parents
grows very large:
1. If the requested size is too large for our stack,
alloca() has no way to tell us, and we simply segfault
while trying to access the memory.
2. It does not use our usual memory_limit_check() logic.
I measured, and alloca is indeed buying us a very small
speedup over xmalloc()/free(). So we'd want to keep
something like it.
This patch simply puts a conditional in place at each
callsite: we use alloca for common known-small numbers of
parents, and otherwise use the heap. We are technically
still vulnerable to (1), but no more so than if we simply
put a few dozen bytes on the stack, which we must do all the
time anyway. And likewise, we technically miss a memory
limit check if it is tiny, but such a limit is pointless.
An alternative to this would be implement something like:
struct tree *tp, tp_fallback[2];
if (nparent <= ARRAY_SIZE(tp_fallback))
tp = tp_fallback;
else
ALLOC_ARRAY(tp, nparent);
...
if (tp != tp_fallback)
free(tp);
That would let us drop our xalloca() portability code
entirely. But in my measurements, this seemed to perform
slightly worse than the xalloca solution.
Note in the example above, and in the patch below, I've used
ALLOC_ARRAY() to replace the manual xmalloc(nr * sizeof(*x)).
Besides being shorter, this has the bonus that one cannot
accidentally overflow a size_t during that computation.

redefinition warning for the SIZE_MAX macro. However, gcc did not issue
any such warning.
After commit 56a1a3ab, in terms of the order of #includes and #defines,
the code looked something like:
However, if you compile that file with -Wsystem-headers, then it will
also issue a warning. Having set -Wsystem-headers in CFLAGS, using the
config.mak file, then (on cygwin):
$ make compat/regex/regex.o

compat/regex/regex_internal.h:108:0: note: this is the location of the previous definition
# define SIZE_MAX ((size_t) -1)
^
$
The compilation of the compat/regex code is somewhat unusual in that the
regex.c file directly #includes the other c files (regcomp.c, regexec.c
and regex_internal.c). Commit 56a1a3ab added an #include of <stdint.h>
to the regcomp.c file, which results in the redefinition, since this is
included after the regex_internal.h header. This header file contains a
'fallback' definition for SIZE_MAX, in order to support systems which do
not have the <stdint.h> header (the HAVE_STDINT_H macro is not defined).
In order to suppress the warning, we move the #include of <stdint.h>
from regcomp.c to the start of the compilation unit, close to the top
of regex.c, prior to the #include of the regex_internal.h header.

reflog: continue walking the reflog past root commits
If a repository contains more than one root commit, then its HEAD
reflog may contain multiple "creation events", i.e. entries whose
"from" value is the null sha1. Listing such a reflog currently stops
prematurely at the first such entry, even when the reflog still
contains older entries. This can scare users into thinking that their
reflog got truncated after 'git checkout --orphan'.
Continue walking the reflog past such creation events based on the
preceeding reflog entry's "new" value.
The test 'symbolic-ref writes reflog entry' in t1401-symbolic-ref
implicitly relies on the current behavior of the reflog walker to stop
at a root commit and thus to list only the reflog entries that are
relevant for that test. Adjust the test to explicitly specify the

rev-list: disable bitmaps when "-n" is used with listing objects
You can ask rev-list to use bitmaps to speed up an --objects
traversal, which should generally give you your answers much
faster.
Likewise, you can ask rev-list to limit such a traversal
with `-n`, in which case we'll show only a limited set of
commits (and only the tree and commit objects directly
reachable from those commits).
But if you do both together, the results are nonsensical. We
end up limiting any fallback traversal we do to _find_ the
bitmaps, but the actual set of objects we output will be
picked arbitrarily from the union of any bitmaps we do find,
and will involve the objects of many more commits.
It's possible that somebody might want this as a "show me
what you can, but limit the amount of work you do" flag.
But as with the prior commit clamping "--count", the results
are basically non-deterministic; you'll get the values from
some commits between `n` and the total number, and you can't
tell which.
And unlike the `--count` case, we can't easily generate the
"real" value from the bitmap values (you can't just walk
back `-n` commits and subtract out the reachable objects
from the boundary commits; the bitmaps for `X` record its
total reachability, so you don't know which objects are
directly from `X` itself, which from `X^`, and so on).
So let's just fallback to the non-bitmap code path in this
case, so we always give a sane answer.

rev-list: "adjust" results of "--count --use-bitmap-index -n"
If you ask rev-list for:
git rev-list --count --use-bitmap-index HEAD
we optimize out the actual traversal and just give you the
number of bits set in the commit bitmap. This is faster,
which is good.
But if you ask to limit the size of the traversal, like:
git rev-list --count --use-bitmap-index -n 100 HEAD
we'll still output the full bitmapped number we found. On
the surface, that might even seem OK. You explicitly asked
to use the bitmap index, and it was cheap to compute the
real answer, so we gave it to you.
But there's something much more complicated going on under
the hood. If we don't have a bitmap directly for HEAD, then
we have to actually traverse backwards, looking for a
bitmapped commit. And _that_ traversal is bounded by our
`-n` count.
This is a good thing, because it bounds the work we have to
do, which is probably what the user wanted by asking for
`-n`. But now it makes the output quite confusing. You might
get many values:
- your `-n` value, if we walked back and never found a
bitmap (or fewer if there weren't that many commits)
- the actual full count, if we found a bitmap root for
every path of our traversal with in the `-n` limit
- any number in between! We might have walked back and
found _some_ bitmaps, but then cut off the traversal
early with some commits not accounted for in the result.
So you cannot even see a value higher than your `-n` and say
"OK, bitmaps kicked in, this must be the real full count".
The only sane thing is for git to just clamp the value to a
maximum of the `-n` value, which means we should output the
exact same results whether bitmaps are in use or not.
The test in t5310 demonstrates this by using `-n 1`.
Without this patch we fail in the full-bitmap case (where we
do not have to traverse at all) but _not_ in the
partial-bitmap case (where we have to walk down to find an
actual bitmap). With this patch, both cases just work.
I didn't implement the crazy in-between case, just because
it's complicated to set up, and is really a subset of the
full-count case, which we do cover.

t2300: run git-sh-setup in an environment that better mimics the real life
When we run scripted Porcelains, "git" potty has set up the $PATH by

dot-source shell script library like git-sh-setup with simple dot
without specifying any path.
t2300 however dot-sources git-sh-setup without adjusting $PATH like

once git-sh-setup wants to rely on the $PATH adjustment, just like
any scripted Porcelains already do, it would become one. It cannot
for example dot-source another shell library without specifying the
full path to it by prefixing $(git --exec-path).
In t5500::check_prot_host_port_path(), diagport is not a variable
used elsewhere and the function is not recursively called so this
can simply lose the "local", which may not be supported by shell
(besides, the function liberally clobbers other variables without
making them "local").
t7403::reset_submodule_urls() overrides the "root" variable used
in the test framework for no good reason; its use is not about
temporarily relocating where the test repositories are created.
This assignment can be made not to clobber the variable by moving
them into the subshells it already uses. Its value is always
$TRASH_DIRECTORY, so we could use it instead there, and this
function that is called only once and its two subshells may not be
necessary (instead, the caller can use "git -C $there config" and
set a value that is derived from $TRASH_DIRECTORY), but this is a
minimum fix that is needed to lose "local".

Junio pointed out `relative_path` was using bashisms via the
local variables. As the longer term goal is to rewrite most of the
submodule code in C, do it now.

In 48308681 (2016-02-29, git submodule update: have a dedicated helper
for cloning), the helper communicated errors back only via exit code,
and dance with printing '#unmatched' in case of error was left to
git-submodule.sh as it uses the output of the helper and pipes it into
shell commands. This change makes the helper consistent by never
printing '#unmatched' in the helper but always handling these piping
issues in the actual shell script.

is unportable when some-program is actually a shell
function, like test_must_fail (on some shells FOO remains
set after the function returns, and on others it does not).
We sometimes get around this by using env, like:
test_must_fail env FOO=BAR some-program
But that only works because test_must_fail's arguments are
themselves a command which can be run. You can't run:
env FOO=BAR test_must_fail some-program
because env does not know about our shell functions. So
there is no equivalent for test_commit, for example, and one
must resort to:
(
FOO=BAR
export FOO
test_commit
)
which is a bit verbose. Let's add a version of "env" that
works _inside_ the shell, by creating a subshell, exporting
variables from its argument list, and running the command.
Its use is demonstrated on a currently-unportable case in
t4014.

Correct faulty recommendation to use "git submodule deinit ." when
de-initialising all submodules, which would result in a strange
error message in a pathological corner case.

Merge branch 'jk/test-send-sh-x-trace-elsewhere' into maint
Running tests with '-x' option to trace the individual command
executions is a useful way to debug test scripts, but some tests
that capture the standard error stream and check what the command
said can be broken with the trace output mixed in. When running
our tests under "bash", however, we can redirect the trace output
to another file descriptor to keep the standard error of programs
being tested intact.

Merge branch 'js/name-rev-use-oldest-ref' into maint
"git describe --contains" often made a hard-to-justify choice of
tag to give name to a given commit, because it tried to come up
with a name with smallest number of hops from a tag, causing an old
commit whose close descendant that is recently tagged were not
described with respect to an old tag but with a newer tag. It did
not help that its computation of "hop" count was further tweaked to
penalize being on a side branch of a merge. The logic has been
updated to favor using the tag with the oldest tagger date, which
is a lot easier to explain to the end users: "We describe a commit
in terms of the (chronologically) oldest tag that contains the
commit."
* js/name-rev-use-oldest-ref:
name-rev: include taggerdate in considering the best name
rebase -i: remove an unnecessary 'rerere' invocation
Interactive rebase uses 'git cherry-pick' and 'git merge' to replay
commits. Both invoke the 'rerere' machinery when they fail due to merge
conflicts. Note that all code paths with these two commands also invoke
the shell function die_with_patch when the commands fail.
Since commit 629716d2 ("rerere: do use multiple variants") the second
operation of the rerere machinery can be observed by a duplicated
message "Recorded preimage for 'file'". This second operation records
the same preimage as the first one and, hence, only wastes cycles.
Remove the 'git rerere' invocation from die_with_patch.
Shell function die_with_patch can be called after the failure of
"git commit", too, which also calls into the rerere machinery, but it
does so only after a successful commit to record the resolution.
Therefore, it is wrong to call 'git rerere' from die_with_patch after
"git commit" fails.

grep: -W: don't extend context to trailing empty lines
Empty lines between functions are shown by grep -W, as it considers them
to be part of the function preceding them. They are not interesting in
most languages. The previous patches stopped showing them for diff -W.
Stop showing empty lines trailing a function with grep -W. Grep scans
the lines of a buffer from top to bottom and prints matching lines
immediately. Thus we need to peek ahead in order to determine if an
empty line is part of a function body and worth showing or not.
Remember how far ahead we peeked in order to avoid having to do so
repeatedly when handling multiple consecutive empty lines.
