This output format prevents format-patch output from breaking
readers if somebody copy+pasted an mbox into a commit message.
Unlike the traditional "mboxo" format, "mboxrd" is designed to
be fully-reversible. "mboxrd" also gracefully degrades to
showing extra ">" in existing "mboxo" readers.
This degradation is preferable to breaking message splitting
completely, a problem I've seen in "mboxcl" due to having
multiple, non-existent, or inaccurate Content-Length headers.
"mboxcl2" is a non-starter since it's inherits the problems
of "mboxcl" while being completely incompatible with existing
tooling based around mailsplit.

"make DEVELOPER=1" worked as expected; setting DEVELOPER=1 in
config.mak didn't.
* mm/makefile-developer-can-be-in-config-mak:

This does not change the behavior, but allows the user to tweak
DEVELOPER_CFLAGS on the command-line or in a config.mak* file if
needed.
This also makes the code somewhat cleaner as it follows the pattern
<initialisation of variables>
<include statements>
<actual build logic>
by specifying which flags to activate in the first part, and actually
activating them in the last one.

The DEVELOPER knob was introduced in 658df95 (add DEVELOPER makefile
knob to check for acknowledged warnings, 2016-02-25), and works well
when used as "make DEVELOPER=1", and when the configure script was not
used.
However, the advice given in CodingGuidelines to add DEVELOPER=1 to
config.mak does not: config.mak is included after testing for
DEVELOPER in the Makefile, and at least GNU Make's manual specifies
"Conditional directives are parsed immediately", hence the config.mak
declaration is not visible at the time the conditional is evaluated.
Also, when using the configure script to generate a
config.mak.autogen, the later file contained a "CFLAGS = <flags>"
initialization, which overrode the "CFLAGS += -W..." triggered by
DEVELOPER.
This patch fixes both issues.

Backticks are emphasized through monospaced styling in the HTML
version of Git documentation. But they were left unstyled in the
manual pages.
To make the man pages more comfortably read, `MAN_BOLD_LITERAL` was
added by 5121a6d (Documentation: option to render literal text as
bold for manpages, 2009-03-27). It allowed the user to build the
manpages with literals in bold style.
For precaution it was not set by default back then.
Since 79c461d (docs: default to more modern toolset, 2010-11-19), it
is assumed ASCIIDOC 8 and at least docbook-xsl 1.73 are used, so the
need for compatibility concern is much lessor now.
Remove `MAN_BOLD_LITERAL`, and typeset literals as bold by default .
Add `NO_MAN_BOLD_LITERAL`, a new Makefile option, disabling this
feature when defined.

"git rebase -i", after it fails to auto-resolve the conflict, had
an unnecessary call to "git rerere" from its very early days, which
was spotted recently; the call has been removed.

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.

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.

"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."

Ideally, each test should be responsible for setting up state it needs
rather than relying upon transient global state. Toward this end, teach
test_rev_parse() to accept a "-g <dir>" option to allow callers to
specify the value of the GIT_DIR environment variable explicitly. Take
advantage of this new option to avoid polluting the global scope with
GIT_DIR assignments.
Implementation note: Typically, tests avoid polluting the global state
by wrapping transient environment variable assignments within a
subshell, however, this technique doesn't work here since test_config()
and test_unconfig() need to know GIT_DIR, as well, but neither function
can be used within a subshell. Consequently, GIT_DIR is instead cleared
manually via test_when_finished().

Ideally, each test should be responsible for setting up state it needs

test_rev_parse() to accept a "-b <value>" option to allow callers to set
"core.bare" explicitly or undefine it. Take advantage of this new option
to avoid setting "core.bare" outside of tests.
Under the hood, "-b <value>" invokes "test_config -C <dir>" (or
"test_unconfig -C <dir>"), thus git-config knows explicitly where to
find its configuration file. Consequently, the global GIT_CONFIG
environment variable required by the manual git-config invocations
outside of tests is no longer needed, and is thus dropped.

Implementation note: test_rev_parse() passes "-C <dir>" along to
git-rev-parse with <dir> properly quoted. The natural and POSIX way to
do so is via ${dir:+-C "$dir"}, however, with some older broken shells,
this expression evaluates incorrectly to a single argument ("-C <dir>")
rather than the expected two (-C and "<dir>"). Work around this problem
with the slightly ungainly expression: ${dir:+-C} ${dir:+"$dir"}

Tests run by test_rev_parse() are nearly identical; each invokes
git-rev-parse with a single option and compares the result against an
expected value. Such duplication makes it onerous to extend the tests
since any change needs to be repeated in each test. Avoid the
duplication by parameterizing the test and driving it via a for-loop.

The final batch of git-rev-parse tests work against a non-local object
database named repo.git. This is done by renaming .git to repo.git and
pointing GIT_DIR at it, but the name is never restored to .git at the
end of the script, which can be problematic for tests added in the
future. Be more friendly by instead making repo.git a copy of .git.
Furthermore, make it clear that tests in repo.git will be independent
from the results of earlier tests done in .git by initializing repo.git
earlier in the test sequence.
Likewise, bundle remaining preparation (such as directory creation) into
a common setup test consistent with modern practice.

Traditionally cat-file's batch-mode does not do any output
buffering. The reason is that a caller may have pipes
connected to its input and output, and would want to use
cat-file interactively, getting output immediately for each
input it sends.
This may involve a lot of small write() calls, which can be
slow. So we introduced --buffer to improve this, but we
can't turn it on by default, as it would break the
interactive case above.
However, when --batch-all-objects is used, we do not read
stdin at all. We generate the output ourselves as quickly as
possible, and then exit. In this case buffering is a strict
win, and it is simply a hassle for the user to have to
remember to specify --buffer.
This patch makes --buffer the default when --batch-all-objects
is used. Specifying "--buffer" manually is still OK, and you
can even override it with "--no-buffer" if you're a
masochist (or debugging).
For some real numbers, running:
git cat-file --batch-all-objects --batch-check='%(objectname)'
on torvalds/linux goes from:
real 0m1.464s
user 0m1.208s
sys 0m0.252s
to:
real 0m1.230s
user 0m1.172s
sys 0m0.056s
for a 16% speedup.

It is not unreasonable to ask cat-file for a batch-check
format of simply "%(objectname)". At first glance this seems
like a noop (you are generally already feeding the object
names on stdin!), but it has a few uses:
1. With --batch-all-objects, you can generate a listing of
the sha1s present in the repository, without any input.
2. You do not have to feed sha1s; you can feed arbitrary
sha1 expressions and have git resolve them en masse.
3. You can even feed a raw sha1, with the result that git
will tell you whether we actually have the object or
not.
In case 3, the call to sha1_object_info is useful; it tells
us whether the object exists or not (technically we could
swap this out for has_sha1_file, but the cost is roughly the
same).
In case 2, the existence check is of debatable value. A
mass-resolution might prefer performance to safety (against
outputting a value for a corrupted ref, for example).
However, the object lookup cost is likely not as noticeable
compared to the resolution cost. And since we have provided
that safety in the past, the conservative choice is to keep
it.
In case 1, though, the object lookup is a definite noop; we
know about the object because we found it in the object
database. There is no new information gained by making the
call.
This patch detects that case and optimizes out the call.
Here are best-of-five timings for linux.git:
[before]
$ time git cat-file --buffer \
--batch-all-objects \
--batch-check='%(objectname)'
real 0m2.117s
user 0m2.044s
sys 0m0.072s
[after]
$ time git cat-file --buffer \
--batch-all-objects \
--batch-check='%(objectname)'
real 0m1.230s
user 0m1.176s
sys 0m0.052s
There are two implementation details to note here.
One is that we detect the noop case by seeing that "struct
object_info" does not request any information. But besides
object existence, there is one other piece of information
which sha1_object_info may fill in: whether the object is
cached, loose, or packed. We don't currently provide that
information in the output, but if we were to do so later,
we'd need to take note and disable the optimization in that
case.
And that leads to the second note. If we were to output
that information, a better implementation would be to
remember where we saw the object in --batch-all-objects in
the first place, and avoid looking it up again by sha1.
In fact, we could probably squeeze out some extra
performance for less-trivial cases, too, by remembering the
pack location where we saw the object, and going directly
there to find its information (like type, size, etc). That
would in theory make this optimization unnecessary.
I didn't pursue that path here for two reasons:
1. It's non-trivial to implement, and has memory
implications. Because we sort and de-dup the list of
output sha1s, we'd have to record the pack information
for each object, too.
2. It doesn't save as much as you might hope. It saves the
find_pack_entry() call, but getting the size and type
for deltified objects requires walking down the delta
chain (for the real type) or reading the delta data
header (for the size). These costs tend to dominate the
non-trivial cases.
By contrast, this optimization is easy and self-contained,
and speeds up a real-world case I've used.

Certain lines of the marks file might be corrupted (or the objects
missing due to a garbage collection), but that's no reason to truncate
the file and essentially destroy the rest of it.
Ideally missing objects should not cause a crash, we could just skip
them, but that's another patch.

In t0008, we have

and expect that the backslash-dq is passed through literally.
ksh88 eats the backslash and produces a wrong expect file to
compare the actual output with.
Using \\" works this around without breaking other POSIX shells
(which collapse backslash-backslash to a single backslash), and
ksh88 does so, too.
It makes it easier to read, too, because the reason why we are
writing backslash there is *not* because we think dq is special and
want to quote it (if that were the case we would have two more
backslashes on that line). It is simply because we want a single
literal backslash there. Since backslash is treated specially in
unquoted here-document, explicitly doubling it to quote it expresses
our intent better than relying on the character that immediately
comes after it (i.e. '"') not being a special character.

test_patch_id_file_order shell function uses $name variable to hold
one filename, and calls another shell function calc_patch_id as a
downstream of one pipeline. The called function, however, also uses
the same $name variable. With a shell implementation that runs the
callee in the current shell environment, the caller's $name would
be clobbered by the callee's use of the same variable.
This hasn't been an issue with dash and bash. ksh93 reveals the
breakage in the test script.
Fix it by using a distinct variable name in the callee.
