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.

Most of the submodule operations work on a set of submodules.
Calculating and using this set is usually done via:
module_list "$@" | {
while read mode sha1 stage sm_path
do
# the actual operation
done
}
Currently the function `module_list` is implemented in the
git-submodule.sh as a shell script wrapping a perl script.
The rewrite is in C, such that it is faster and can later be
easily adapted when other functions are rewritten in C.
git-submodule.sh, similar to the builtin commands, will navigate
to the top-most directory of the repository and keep the
subdirectory as a variable. As the helper is called from
within the git-submodule.sh script, we are already navigated
to the root level, but the path arguments are still relative
to the subdirectory we were in when calling git-submodule.sh.
That's why there is a `--prefix` option pointing to an alternative
path which to anchor relative path arguments.

527ec39 (generate-cmdlist: parse common group commands, 2015-05-21)
replaced generate-cmdlist.sh with a more functional Perl version,
generate-cmdlist.perl. The Perl version gleans named tags from a new
"common groups" section in command-list.txt and recognizes those
tags in "command list" section entries in place of the old 'common'
tag. This allows git-help to, not only recognize, but also group
common commands.
Although the tests require Perl, 527ec39 creates an unconditional
dependence upon Perl in the build system itself, which can not be
overridden with NO_PERL. Such a dependency may be undesirable; for
instance, the 'git-lite' package in the FreeBSD ports tree is
intended as a minimal Git installation (which may, for example, be
useful on servers needing only local clone and update capability),
which, historically, has not depended upon Perl[1].
Therefore, revive generate-cmdlist.sh and extend it to recognize
"common groups" and its named tags. Retire generate-cmdlist.perl.

* hv/submodule-config:
submodule: allow erroneous values for the fetchRecurseSubmodules option
submodule: use new config API for worktree configurations
submodule: extract functions for config set and lookup
submodule: implement a config API for lookup of .gitmodules values
In a superproject some commands need to interact with submodules. They
need to query values from the .gitmodules file either from the worktree
of from certain revisions. At the moment this is quite hard since a
caller would need to read the .gitmodules file from the history and then
parse the values. We want to provide an API for this so we have one
place to get values from .gitmodules from any revision (including the
worktree).
The API is realized as a cache which allows us to lazily read
.gitmodules configurations by commit into a runtime cache which can then
be used to easily lookup values from it. Currently only the values for
path or name are stored but it can be extended for any value needed.
It is expected that .gitmodules files do not change often between
commits. Thats why we lookup the .gitmodules sha1 from a commit and then
either lookup an already parsed configuration or parse and cache an
unknown one for each sha1. The cache is lazily build on demand for each
requested commit.
This cache can be used for all purposes which need knowledge about
submodule configurations. Example use cases are:
* Recursive submodule checkout needs to lookup a submodule name from
its path when a submodule first appears. This needs be done before
this configuration exists in the worktree.
* The implementation of submodule support for 'git archive' needs to
lookup the submodule name to generate the archive when given a
revision that is not checked out.
* 'git fetch' when given the --recurse-submodules=on-demand option (or
configuration) needs to lookup submodule names by path from the
database rather than reading from the worktree. For new submodule it
needs to lookup the name from its path to allow cloning new
submodules into the .git folder so they can be checked out without
any network interaction when the user does a checkout of that
revision.

At the beginning of the rewrite of git-am.sh to C, in order to not break

environment variable _GIT_USE_BUILTIN_AM was not defined.

For the purpose of rewriting git-am.sh into a C builtin, implement a
skeletal builtin/am.c that redirects to $GIT_EXEC_PATH/git-am if the
environment variable _GIT_USE_BUILTIN_AM is not defined. Since in the
Makefile git-am.sh takes precedence over builtin/am.c,
$GIT_EXEC_PATH/git-am will contain the shell script git-am.sh, and thus
this allows us to fall back on the functional git-am.sh when running the
test suite for tests that depend on a working git-am implementation.
Since git-am.sh cannot handle any environment modifications by
setup_git_directory(), "am" is declared with no setup flags in git.c. On
the other hand, to re-implement git-am.sh in builtin/am.c, we need to
run all the git dir and work tree setup logic that git.c typically does
for us. As such, we work around this temporarily by copying the logic in
git.c's run_builtin(), which is roughly:
prefix = setup_git_directory();
trace_repo_setup(prefix);
setup_work_tree();
This redirection should be removed when all the features of git-am.sh
have been re-implemented in builtin/am.c.

GSoC project to rebuild ref listing by branch and tag based on the
for-each-ref machinery. This is its first part.
* kn/for-each-ref:
ref-filter: make 'ref_array_item' use a FLEX_ARRAY for refname
for-each-ref: introduce filter_refs()
ref-filter: move code from 'for-each-ref'
ref-filter: add 'ref-filter.h'
for-each-ref: rename variables called sort to sorting
for-each-ref: rename some functions and make them public
for-each-ref: introduce 'ref_array_clear()'
for-each-ref: introduce new structures for better organisation
for-each-ref: rename 'refinfo' to 'ref_array_item'
for-each-ref: clean up code
for-each-ref: extract helper functions out of grab_single_ref()
Move most of the code from 'for-each-ref' to 'ref-filter' to make
it publicly available to other commands, this is to unify the code
of 'tag -l', 'branch -l' and 'for-each-ref' so that they can share
their implementations with each other.
Add 'ref-filter' to the Makefile, this completes the movement of code
from 'for-each-ref' to 'ref-filter'.

For the purpose of rewriting git-pull.sh into a C builtin, implement a
skeletal builtin/pull.c that redirects to $GIT_EXEC_PATH/git-pull.sh if
the environment variable _GIT_USE_BUILTIN_PULL is not defined. This
allows us to fall back on the functional git-pull.sh when running the
test suite for tests that depend on a working git-pull implementation.
This redirection should be removed when all the features of git-pull.sh
have been re-implemented in builtin/pull.c.

We spend a lot of time in strbuf_getwholeline in a tight
loop reading characters from a stdio handle into a buffer.
The libc getdelim() function can do this for us with less
overhead. It's in POSIX.1-2008, and was a GNU extension
before that. Therefore we can't rely on it, but can fall
back to the existing getc loop when it is not available.
The HAVE_GETDELIM knob is turned on automatically for Linux,
where we have glibc. We don't need to set any new
feature-test macros, because we already define _GNU_SOURCE.
Other systems that implement getdelim may need to other
macros (probably _POSIX_C_SOURCE >= 200809L), but we can
address that along with setting the Makefile knob after
testing the feature on those systems.

The gettext N_ macro is used to mark strings for translation
without actually translating them. At runtime the string is
expected to be passed to the gettext API for translation.
If two N_ macro invocations appear next to each other with only
whitespace (or nothing at all) between them, the two separate
strings will be marked for translation, but the preprocessor
will then silently combine the strings into one and at runtime
the string passed to gettext will not match the strings that
were translated so no translation will actually occur.
Avoid this by adding parentheses around the expansion of the
N_ macro so that instead of ending up with two adjacent strings
that are then combined by the preprocessor, two adjacent strings
surrounded by parentheses result instead which causes a compile
error so the mistake can be quickly found and corrected.
However, since these string literals are typically assigned to
static variables and not all compilers support parenthesized
string literal assignments, allow this to be controlled by the
Makefile with the default only enabled when the compiler is
known to support the syntax.
For now only __GNUC__ enables this by default which covers both
gcc and clang which should result in early detection of any
adjacent N_ macros.
Although the necessary tests make the affected files a bit less
elegant, the benefit of avoiding propagation of a translation-
marking error to all the translation teams thus creating extra
work for them when the error is eventually detected and fixed
would seem to outweigh the minor inelegance the additional
configuration tests introduce.

This adds simple wrapper functions around calls to stat(), fstat(),

bits to those used by most operating systems. It also rewrites the
S_IF* macros to the common values, so all file type processing is
performed using the translated modes. This makes projects portable
across operating systems that use different file type definitions.
Only the file type bits may be affected by these compatibility
functions; the file permission bits are assumed to be 07777 and are
passed through unchanged.

If NO_PERL is not set, our perl scripts are built as
usual. If it is set, then we build "dummy" versions that
tell you git was built without perl support and exit
gracefully.
However, if you switch to NO_PERL in a directory with
existing build artifacts, we do not notice that the files
need rebuilt. We see only that they are newer than the
"unimplemented.sh" wrapper and assume they are done. So
doing:
make
make NO_PERL=Nope
would result in a git-add--interactive script that uses perl
(and running the test suite would make use of it).
Instead, we should trigger a rebuild of the perl scripts
anytime NO_PERL changes.

Use libcurl's high-level API functions to implement git-imap-send
instead of the previous low-level OpenSSL-based functions.
Since version 7.30.0, libcurl's API has been able to communicate with
IMAP servers. Using those high-level functions instead of the current
ones would reduce imap-send.c by some 1200 lines of code. For now,
the old ones are wrapped in #ifdefs, and the new functions are enabled
by make if curl's version is >= 7.34.0, from which version on curl's
CURLOPT_LOGIN_OPTIONS (enabling IMAP authentication) parameter has been
available. The low-level functions will still be used for tunneling
into the server for now.
As I don't have access to that many IMAP servers, I haven't been able to
test the new code with a wide variety of parameter combinations. I did
test both secure and insecure (imaps:// and imap://) connections and
values of "PLAIN" and "LOGIN" for the authMethod.
In order to suppress a sparse warning about "using sizeof on a
function", we use the same solution used in commit 9371322a6
("sparse: suppress some "using sizeof on a function" warnings",
06-10-2013) which solved exactly this problem for the other commands
using libcurl.

Technically this could still be used to find a dependency

Most modern platforms will use automatically computed header
dependencies to figure out when a C file needs rebuilt due
to a header changing. With old compilers, however, we
fallback to a static list of header files. If any of them
changes, we recompile everything. This is overly
conservative, but the best we can do on older platforms.
It is unfortunately easy for our static header list to grow
stale, as none of the regular developers make use of it.
Instead of trying to keep it up to date, let's invoke "find"
to generate the list dynamically.
Since we do not use the value $(LIB_H) unless either
COMPUTE_HEADER_DEPENDENCIES is turned on or the user is
building "po/git.pot" (where it comes in via $(LOCALIZED_C),
make is smart enough to not even run this "find" in most
cases. However, we do need to stop using the "immediate"
variable assignment ":=" for $(LOCALIZED_C). That's OK,
because it was not otherwise useful here.

po/git.pot is normally used as-is and not regenerated by people
building git, so it is okay if an explicit "make po/git.pot" always
automatically regenerates it. Depend on the magic FORCE target
instead of explicitly keeping track of dependencies.
This simplifies the makefile, in particular preparing for a moment
when $(LIB_H), which is part of $(LOCALIZED_C), can be computed on the
fly. It also fixes a slight breakage in which changes to perl and shell
scripts did not trigger a rebuild of po/git.pot.
We still need a dependency on GENERATED_H, to force those files to be

Since 5d7fd6d we run the perf tests as part of "make

Add a getnanotime() function that returns nanoseconds since 01/01/1970 as
unsigned 64-bit integer (i.e. overflows in july 2554). This is easier to
work with than e.g. struct timeval or struct timespec. Basing the timer on
the epoch allows using the results with other time-related APIs.
To simplify adaption to different platforms, split the implementation into
a common getnanotime() and a platform-specific highres_nanos() function.
The common getnanotime() function handles errors, falling back to
gettimeofday() if highres_nanos() isn't implemented or doesn't work.
getnanotime() is also responsible for normalizing to the epoch. The offset
to the system clock is calculated only once on initialization, i.e.
manually setting the system clock has no impact on the timer (except if
the fallback gettimeofday() is in use). Git processes are typically short
lived, so we don't need to handle clock drift.
The highres_nanos() function returns monotonically increasing nanoseconds
relative to some arbitrary point in time (e.g. system boot), or 0 on
failure. Providing platform-specific implementations should be relatively
easy, e.g. adapting to clock_gettime() as defined by the POSIX realtime
extensions is seven lines of code.
This version includes highres_nanos() implementations for:
* Linux: using clock_gettime(CLOCK_MONOTONIC)
* Windows: using QueryPerformanceCounter()
Todo:
* enable clock_gettime() on more platforms
* add Mac OSX version, e.g. using mach_absolute_time + mach_timebase_info

Profile feedback always failed for me with -jN. The problem
was that there was no implicit ordering between the profile generate
stage and the profile use stage. So some objects in the later stage
would be linked with profile generate objects, and fail due
to the missing -lgcov.
This adds a new profile target that implicitely enforces the
correct ordering by using submakes. Plus a profile-install target
to also install. This is also nicer to type that PROFILE=...
Plus I always run the performance test suite now for the full
profile run.
In addition I also added a profile-fast / profile-fast-install
target the only runs the performance test suite instead of the
whole test suite. This significantly speeds up the profile build,
which was totally dominated by test suite run time. However
it may have less coverage of course.

We used to disable threaded "git index-pack" on platforms without
thread-safe pread(); use a different workaround for such
platforms to allow threaded "git index-pack".

index-pack: work around thread-unsafe pread()
Commit signatures can be verified using "git show -s --show-signature"
or the "%G?" pretty format and parsing the output, which is well suited
for user inspection, but not for scripting.
Provide a command "verify-commit" which is analogous to "verify-tag": It
returns 0 for good signatures and non-zero otherwise, has the gpg output
on stderr and (optionally) the commit object on stdout, sans the
signature, just like "verify-tag" does.

This split-index mode is designed to keep write cost proportional to
the number of changes the user has made, not the size of the work
tree. (Read cost is another matter, to be dealt separately.)
This mode stores index info in a pair of $GIT_DIR/index and
$GIT_DIR/sharedindex.<SHA-1>. sharedindex is large and unchanged over
time while "index" is smaller and updated often. Format details are in
index-format.txt, although not everything is implemented in this
patch.
Shared indexes are not automatically removed, because it's unclear if
the shared index is needed by any (even temporary) indexes by just
looking at it. After a while you'll collect stale shared indexes. The
good news is one shared index is useable for long, until
$GIT_DIR/index becomes too big and sluggish that the new shared index
must be created.
The safest way to clean shared indexes is to turn off split index
mode, so shared files are all garbage, delete them all, then turn on
split index mode again.

Update the logic to compute the display width needed for utf8
strings and allow us to more easily maintain the tables used in

Instead of running N pair-wise diff-trees when inspecting a
N-parent merge, find the set of paths that were touched by walking
N+1 trees in parallel. These set of paths can then be turned into
N pair-wise diff-tree results to be processed through rename
detections and such. And N=2 case nicely degenerates to the usual
2-way diff-tree, which is very nice.

The function git_wcwidth() returns for a given unicode code point the
width on the display:
-1 for control characters,
0 for combining or other non-visible code points
1 for e.g. ASCII
2 for double-width code points.
This table had been originally been extracted for one Unicode
version, probably 3.2.
We now use two tables these days, one for zero-width and another for
double-width. Make it easier to update these tables to a later
version of Unicode by factoring out the table from utf8.c into
unicode_width.h and add the script update_unicode.sh to update the
table based on the latest Unicode specification files.

It turns out that some platforms do ship without curl-config even
though they build with the hardcoded default -lcurl and rely on it
to work.
* db/make-with-curl:
Makefile: default to -lcurl when no CURL_CONFIG or CURLDIR
The original implementation of CURL_CONFIG support did not match the
original behavior of using -lcurl when CURLDIR was not set. This broke
implementations that were lacking curl-config but did have libcurl
installed along system libraries, such as MSysGit. In other words, the
assumption that curl-config is always installed was incorrect.
Instead, if CURL_CONFIG is empty or returns an empty result (e.g. due
to curl-config being missing), use the old behavior of falling back to
-lcurl.

When extract l10n messages, we use "--add-comments" option to keep
comments right above the l10n messages for references. But sometimes
irrelevant comments are also extracted. For example in the following
code block, the comment in line 2 will be extracted as comment for the
l10n message in line 3, but obviously it's wrong.
{ OPTION_CALLBACK, 0, "ignore-removal", &addremove_explicit,
NULL /* takes no arguments */,
N_("ignore paths removed in the working tree (same as
--no-all)"),
PARSE_OPT_NOARG, ignore_removal_cb },
Since almost all comments for l10n translators are marked with the same
prefix (tag): "TRANSLATORS:", it's safe to only extract comments with
this special tag. I.E. it's better to call xgettext as:
xgettext --add-comments=TRANSLATORS: ...
Also tweaks the multi-line comment in "init-db.c", to make it start with
the proper tag, not "* TRANSLATORS:" (which has a star before the tag).

Multi-threaing of index-pack was disabled with c0f8654
(index-pack: Disable threading on cygwin - 2012-06-26), because
pread() implementations for Cygwin and MSYS were not thread
safe. Recent Cygwin does offer usable pread() and we enabled
multi-threading with 103d530f (Cygwin 1.7 has thread-safe pread,
2013-07-19).
Work around this problem on platforms with a thread-unsafe
pread() emulation by opening one file handle per thread; it
would prevent parallel pread() on different file handles from
stepping on each other.
Also remove NO_THREAD_SAFE_PREAD that was introduced in c0f8654
because it's no longer used anywhere.
This workaround is unconditional, even for platforms with
thread-safe pread() because the overhead is small (a couple file
handles more) and not worth fragmenting the code.

curl-config should always be installed alongside a curl distribution,
and its purpose is to provide flags for building against libcurl, so
use it instead of guessing flags and dependent libraries.
Allow overriding CURL_CONFIG to a custom path to curl-config, to
compile against a curl installation other than the first in PATH.
Depending on the set of features curl is compiled with, there may be
more libraries required than the previous two options of -lssl and
-lidn. For example, with a vanilla build of libcurl-7.36.0 on Mac OS X
10.9:
$ ~/d/curl-out-7.36.0/lib/curl-config --libs
-L/Users/dborowitz/d/curl-out-7.36.0/lib -lcurl -lgssapi_krb5 -lresolv -lldap -lz
Use this only when CURLDIR is not explicitly specified, to continue
supporting older builds.

Most gmtime implementations return a NULL value when they
encounter an error (and this behavior is specified by ANSI C
and POSIX). FreeBSD's implementation, however, will simply
leave the "struct tm" untouched. Let's also recognize this
and convert it to a NULL (with this patch, t4212 should pass
on FreeBSD).
