For example, when PAGER quits and git detects it with

Portable alloca for Git
In the next patch we'll have to use alloca() for performance reasons,
but since alloca is non-standardized and is not portable, let's have a
trick with compatibility wrappers:
1. at configure time, determine, do we have working alloca() through
alloca.h, and define
This way, for systems, where alloca is available, we'll have optimal
on-stack allocations with fast executions. On the other hand, on
systems, where alloca is not available, this gracefully fallbacks to
xmalloc/free.
Both autoconf and config.mak.uname configurations were updated. For
autoconf, we are not bothering considering cases, when no alloca.h is
available, but alloca() works some other way - its simply alloca.h is
available and works or not, everything else is deep legacy.
For config.mak.uname, I've tried to make my almost-sure guess for where
alloca() is available, but since I only have access to Linux it is the
only change I can be sure about myself, with relevant to other changed
systems people Cc'ed.

SunOS and Windows had explicit -DHAVE_ALLOCA_H in their configurations.

diff_tree
show_path
diff_tree_sha1
diff_tree

The downside is that try_to_follow_renames(), if active, we cause
re-reading of 2 initial trees, which was negligible based on my timings,
and which is outweighed cogently by the upsides.

tree-diff: remove special-case diff-emitting code for empty-tree cases
While walking trees, we iterate their entries from lowest to highest in
sort order, so empty tree means all entries were already went over.
If we artificially assign +infinity value to such tree "entry", it will
go after all usual entries, and through the usual driver loop we will be
taking the same actions, which were hand-coded for special cases, i.e.
t1 empty, t2 non-empty
pathcmp(+∞, t2) -> +1
show_path(/*t1=*/NULL, t2); /* = t1 > t2 case in main loop */
t1 non-empty, t2-empty
pathcmp(t1, +∞) -> -1
show_path(t1, /*t2=*/NULL); /* = t1 < t2 case in main loop */
In other words when we have t1 and t2, we return a sign that tells the
caller to indicate the "earlier" one to be emitted, and by returning the
sign that causes the non-empty side to be emitted, we will automatically
cause the entries from the remaining side to be emitted, without
attempting to touch the empty side at all. We can teach
tree_entry_pathcmp() to pretend that an empty tree has an element that
sorts after anything else to achieve this.
Right now we never go to when compared tree descriptors are both
infinity, as this condition is checked in the loop beginning as
finishing criteria, but will do so in the future, when there will be
several parents iterated simultaneously, and some pair of them would run
to the end.

apply --ignore-space-change: lines with and without leading whitespaces do not match
The fuzzy_matchlines() function is used when attempting to resurrect
a patch that is whitespace-damaged, or when applying a patch that
was produced against an old codebase to the codebase after
indentation change.
The patch may want to change a line "a_bc" ("_" is used throught
this description for a whitespace to make it stand out) in the
original into something else, and we may not find "a_bc" in the
current source, but there may be "a__bc" (two spaces instead of one
the whitespace-damaged patch claims to expect). By ignoring the
amount of whitespaces, it forces "git apply" to consider that "a_bc"
in the broken patch meant to refer to "a__bc" in reality.
However, the implementation special cases a run of whitespaces at
the beginning of a line and makes "abc" match "_abc", even though a
whitespace in the middle of string never matches a 0-width gap,
e.g. "a_bc" does not match "abc". A run of whitespace at the end of
one string does not match a 0-width end of line on the other line,
either, e.g. "abc_" does not match "abc".
Fix this inconsistency by making the code skip leading whitespaces
only when both strings begin with a whitespace. This makes the
option mean the same as the option of the same name in "diff" and
"git diff".
Note that I am not sure if anybody sane should use this option in
the first place. The fuzzy match logic may be able to find the
original line that the patch author may have meant to touch because
it does not fully trust what the original lines say (i.e. context
lines prefixed by " " and old lines prefixed by "-" does not have to
exactly match the contents the patch is applied to). There is no
reason for us to trust what the replacement lines (i.e. new lines
prefixed by "+") say, either, but with this option enabled, we end
up copying these new lines with suspicious whitespace distributions
literally into the patched result. But as long as we keep it, we
should make it do its insane thing consistently.
We need to consider that a remote-tracking branch may match more than
one rhs of a fetch refspec. In such a case, it is not enough to stop at
the first match but look at all of the matches in order to determine
whether a head is stale.
To this goal, introduce a variant of query_refspecs which returns all of
the matching refspecs and loop over those answers to check for
staleness.

userdiff: have 'cpp' hunk header pattern catch more C++ anchor points
The hunk header pattern 'cpp' is intended for C and C++ source code, but
it is actually not particularly useful for the latter, and even misses
some use-cases for the former.
The parts of the pattern have the following flaws:
- The first part matches an identifier followed immediately by a colon
and arbitrary text and is intended to reject goto labels and C++
access specifiers (public, private, protected). But this pattern also
rejects C++ constructs, which look like this:
- The second part matches an identifier followed by a list of qualified
names (i.e. identifiers separated by the C++ scope operator '::')
separated by space or '*' followed by an opening parenthesis (with
space between the tokens). It matches function declarations like
struct item* get_head(...
int Outer::Inner::Func(...
Since the pattern requires at least two identifiers, GNU-style
function definitions are ignored:
void
func(...
Moreover, since the pattern does not allow punctuation other than '*',
the following C++ constructs are not recognized:
. template definitions:
template<class T> int func(T arg)
. operator definitions:
Value operator+(Value l, Value r)
- The third part of the pattern finally matches compound definitions.
But it forgets about unions and namespaces, and also skips single-line
definitions
struct random_iterator_tag {};
because no semicolon can occur on the line.
Change the first pattern to require a colon at the end of the line
(except for trailing space and comments), so that it does not reject
constructor or destructor definitions.
Notice that all interesting anchor points begin with an identifier or
keyword. But since there is a large variety of syntactical constructs
after the first "word", the simplest is to require only this word and
accept everything else. Therefore, this boils down to a line that begins
with a letter or underscore (optionally preceded by the C++ scope
operator '::' to accept functions returning a type anchored at the
global namespace). Replace the second and third part by a single pattern
that picks such a line.
This has the following desirable consequence:
- All constructs mentioned above are recognized.
and the following likely desirable consequences:
- Definitions of global variables and typedefs are recognized:
but also the following possibly undesirable consequence:
- When a label is not on a line by itself (except for a comment) it is
no longer rejected, but can appear as a hunk header if it occurs at
the beginning of a line:
next:;

large margin.

t0001: make symlink reinit test more careful
In the final test of t0001, we have a repo whose .git is a
symlink to a directory "here", and we use
"--separate-git-dir" to migrate that to a .git file pointing
to a different directory. We check that the data is migrated
to the new directory and that .git looks like a git-file.
We also check that "here" is not a directory, which is
slightly misleading. It should not be a directory, but
neither should it be gone. It is the actual resting place of
the git-file, and .git remains a symlink to it.
Let's check that more explicitly, both to make our test more
robust, and to make further cleanups in this area more
obvious.

t: prefer "git config --file" to GIT_CONFIG
Doing:
GIT_CONFIG=foo git config ...
is equivalent to:
git config --file=foo ...
The latter is easier to read and slightly less error-prone,
because of issues with one-shot variables and shell
functions (e.g., you cannot use the former with
test_must_fail).
Note that we explicitly leave one case in t1300 which checks
the same operation on both GIT_CONFIG and "git config
--file". They are equivalent in the code these days, but
this will make sure it remains so.

Some tests want to check or set config in another
repository. E.g., t1000 creates repositories and makes sure
that their core.bare and core.worktree settings are what we

GIT_CONFIG=$repo/.git/config git config ...

(cd $repo && git config ...)

t: drop useless sane_unset GIT_* calls
Several test scripts manually unset GIT_CONFIG and other
GIT_* variables. These are generally taken care of for us by
test-lib.sh already.
Unsetting these is not only useless, but can be confusing to
a reader, who may wonder why some tests in a script unset
them and others do not (t0001 is particularly guilty of this
inconsistency, probably because many of its tests predate
the test-lib.sh environment-cleansing).
Note that we cannot always get rid of such unsetting. For
example, t9130 can drop the GIT_CONFIG unset, but not the
GIT_DIR one, because lib-git-svn.sh sets the latter. And in
t1000, we unset GIT_TEMPLATE_DIR, which is explicitly
initialized by test-lib.sh.

t/Makefile: stop setting GIT_CONFIG
Once upon a time, the setting of GIT_CONFIG in the

setting config variables with an alternative GIT_CONFIG,
2006-06-20) unconditionally set GIT_CONFIG in the Makefile
when running tests to give us a known starting point.
This is insufficient for running the tests outside of the
Makefile, however, and 8565d2d (Make tests independent of
global config files, 2007-02-15) later set GIT_CONFIG
directly in test-lib.sh. At that point the Makefile setting

It does, but we'll be reworking it in the next patch after it won't, and
besides it is better to stick to standard
strcmp/memcmp/base_name_compare/etc... convention, where comparison
function returns <0, =0, >0
Regarding performance, comparing for <0, =0, >0 should be a little bit
faster, than switch, because it is just 1 test-without-immediate
instruction and then up to 3 conditional branches, and in switch you
have up to 3 tests with immediate and up to 3 conditional branches.
No worry, that update_tree_entry(t2) is duplicated for =0 and >0 - it
will be good after we'll be adding support for multiparent walker and
will stay that way.

tree-diff: consolidate code for emitting diffs and recursion in one place
Currently both compare_tree_entry() and show_entry() invoke opt diff
callbacks (opt->add_remove() and opt->change()), and also they both have
code which decides whether to recurse into sub-tree, and whether to emit
a tree as separate entry if DIFF_OPT_TREE_IN_RECURSIVE is set.
I.e. we have code duplication and logic scattered on two places.
Let's consolidate it - all diff emiting code and recurion logic moves
to show_entry, which is now named as show_path, because it shows diff
for a path, based on up to two tree entries, with actual diff emitting
code being kept in new helper emit_diff() for clarity.
What we have as the result, is that compare_tree_entry is now free from
code with logic for diff generation, and also performance is not
affected as timings for
`git log --raw --no-abbrev --no-renames`
for navy.git and `linux.git v3.10..v3.11`, just like in previous patch,
