Introduce 'struct refspec', an abstraction around a collection of
'struct refspec_item's much like how 'struct pathspec' holds a
collection of 'struct pathspec_item's.
A refspec struct also contains an array of the original refspec strings
which will be used to facilitate the migration to using this new
abstraction throughout the code base.

The short and sweet PREFIX can be confused when used in many places.
Rename both usages to better describe their purpose. EXEC_CMD_PREFIX is
used in full to disambiguate it from the nearby GIT_EXEC_PATH.
The PREFIX in sideband.c, while nominally independant of the exec_cmd
PREFIX, does reside within libgit[1], so the definitions would clash
when taken together with a PREFIX given on the command line for use by
exec_cmd.c.
Noticed when compiling Git for Windows using MSVC/Visual Studio [1] which
reports the conflict beteeen the command line definition and the
definition in sideband.c within the libgit project.
[1] the libgit functions are brought into a single sub-project
within the Visual Studio construction script provided in contrib,
and hence uses a single command for both exec_cmd.c and sideband.c.

gettext: avoid initialization if the locale dir is not present
The runtime of a simple `git.exe version` call on Windows is currently
dominated by the gettext setup, adding a whopping ~150ms to the ~210ms
total.
Given that this cost is added to each and every git.exe invocation goes
through common-main's invocation of git_setup_gettext(), and given that
scripts have to call git.exe dozens, if not hundreds, of times, this is
a substantial performance penalty.
This is particularly pointless when considering that Git for Windows
ships without localization (to keep the installer's size to a bearable
~34MB): all that time setting up gettext is for naught.
To be clear, Git for Windows *needs* to be compiled with localization,
for the following reasons:
- to allow users to copy add-on localization in case they want it, and
- to fix the nasty error message
BUG: your vsnprintf is broken (returned -1)
by using libgettext's override of vsnprintf() that does not share the
behavior of msvcrt.dll's version of vsnprintf().
So let's be smart about it and skip setting up gettext if the locale
directory is not even present.
Since localization might be missing for not-yet-supported locales, this
will not break anything.

Makefile: quote $INSTLIBDIR when passing it to sed
f6a0ad4b (Makefile: generate Perl header from template file,
2018-04-10) moved code for generating the 'use lib' lines at the top
of perl scripts from the $(SCRIPT_PERL_GEN) rule to a separate
GIT-PERL-HEADER rule.
This rule first populates INSTLIBDIR and then substitutes it into the
GIT-PERL-HEADER using sed:
INSTLIBDIR=... something ...
sed -e 's=@@INSTLIBDIR@@='$$INSTLIBDIR'=g' $< > $@
Because $INSTLIBDIR is not surrounded by double quotes, the shell
splits it at each space, causing errors if INSTLIBDIR contains an $IFS
character:
Junio noticed that this variable is not quoted correctly when it is
passed to sed. As a shell-quoted string, it should be inside
single-quotes like $(perllibdir_relative_SQ), not outside them like
$INSTLIBDIR.
In fact, this substitution variable is not used. Simplify by removing
it.

This is a follow-up to a6c786fce8 (Mark http-fetch without -a as
deprecated, 2011-08-23). For more than six years, we have been warning
when `-a` is not provided, and the documentation has been saying that
`-a` will become the default.
It is a bit unclear what "default" means here. There is no such thing as
`http-fetch --no-a`. But according to my searches, no-one has been
asking on the mailing list how they should silence the warning and
prepare for overriding the flipped default. So let's assume that
everybody is happy with `-a`. They should be, since not using it may
break the repo in such a way that Git itself is unable to fix it.
Always behave as if `-a` was given. Since `-a` implies `-c` (get commit
objects) and `-t` (get trees), all three options are now unnecessary.
Document all of these as historical artefacts that have no effect.
Leave no-op code for handling these options in http-fetch.c. The
options-handling is currently rather loose. If someone tightens it, we
will not want these ignored options to accidentally turn into hard
errors.
Since `-a` was the only safe and sane usage and we have been pushing
people towards it for a long time, refrain from warning when it is used
"unnecessarily" now. Similarly, do not add anything scary-looking to the
man-page about how it will be removed in the future. We can always do so
later. (It is not like we are in desperate need of freeing up
one-letter arguments.)

This is an attempt to resolve an issue I experience with people that are
new to Git -- especially colleagues in a team setting -- where they miss
that their push to a remote location failed because the failure and
success both return a block of white text.
An example is if I push something to a remote repository and then a
colleague attempts to push to the same remote repository and the push
fails because it requires them to pull first, but they don't notice
because a success and failure both return a block of white text. They
then continue about their business, thinking it has been successfully
pushed.
This patch colorizes the errors and hints (in red and yellow,
respectively) so whenever there is a failure when pushing to a remote
repository that fails, it is more noticeable.

So far, we only ever asked whether stdout wants to be colorful. In the
upcoming patches, we will want to make push errors more prominent, which
are printed to stderr, though.
So let's refactor the want_color() function into a want_color_fd()
function (which expects to be called with fd == 1 or fd == 2 for stdout
and stderr, respectively), and then define the macro `want_color()` to
use the want_color_fd() function.
And then also add a macro `want_color_stderr()`, for convenience and
for documentation.

config.c: introduce 'git_config_color' to parse ANSI colors
In preparation for adding `--type=color` to the `git-config(1)` builtin,
let's introduce a color parsing utility, `git_config_color` in a similar
fashion to `git_config_<type>`.
Signed-off-by: Taylor Blau <me@ttaylorr.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
For some use cases, callers of the `git-config(1)` builtin would like to
fallback to default values when the variable asked for does not exist.
In addition, users would like to use existing type specifiers to ensure
that values are parsed correctly when they do exist in the
configuration.
For example, to fetch a value without a type specifier and fallback to
`$fallback`, the following is required:
$ git config core.foo || echo "$fallback"
This is fine for most values, but can be tricky for difficult-to-express
`$fallback`'s, like ANSI color codes.
This motivates `--get-color`, which is a one-off exception to the normal
type specifier rules wherein a user specifies both the configuration
variable and an optional fallback. Both are formatted according to their
type specifier, which eases the burden on the user to ensure that values
are correctly formatted.
This commit (and those following it in this series) aim to eventually
replace `--get-color` with a consistent alternative. By introducing
`--default`, we allow the `--get-color` action to be promoted to a
`--type=color` type specifier, retaining the "fallback" behavior via the
`--default` flag introduced in this commit.
Values filled by `--default` behave exactly as if they were present in
the affected configuration file; they will be parsed by type specifiers
without the knowledge that they are not themselves present in the
configuration.
Specifically, this means that the following will work:
The former is because the function is not prepared to see arg==NULL
(for "--no-expire", it is a norm; "--expire" at the end of the
command line could be made to pass NULL, if it is told that the
argument is optional, but we don't so we do not have to worry about
that case).
The latter is because it does not check the value returned from the
underlying parse_expiry_date().
This seems to be a recent regression introduced while we attempted
to avoid spewing the entire usage message when given a correct
option but with an invalid value at 3bb0923f ("parse-options: do not
show usage upon invalid option value", 2018-03-22). Before that, we
didn't fail silently but showed a full usage help (which arguably is
not all that better).
Also catch this error early when "git gc --prune=<expiration>" is
misspelled by doing a dummy parsing before the main body of "gc"
that is time consuming even begins. Otherwise, we'd spend time to
pack objects and then later have "git prune" first notice the error.
Aborting "gc" in the middle that way is not harmful but is ugly and
can be avoided.

fast-export: fix regression skipping some merge-commits
7199203937 (object_array: add and use `object_array_pop()`, 2017-09-23)
noted that the pattern `object = array.objects[--array.nr].item` could
be abstracted as `object = object_array_pop(&array)`.
Unfortunately, one of the conversions was horribly wrong. Between
grabbing the last object (i.e., peeking at it) and decreasing the object
count, the original code would sometimes return early. The updated code
on the other hand, will always pop the last element, then maybe do the
early return without doing anything with the object.
The end result is that merge commits where all the parents have still
not been exported will simply be dropped, meaning that they will be
completely missing from the exported data.
Re-add a commit when it is not yet time to handle it. An alternative
that was considered was to peek-then-pop. That carries some risk with it
since the peeking and popping need to act on the same object, in a
concerted fashion.
Add a test that would have caught this.

builtin/config.c: support `--type=<type>` as preferred alias for `--<type>`
`git config` has long allowed the ability for callers to provide a 'type
specifier', which instructs `git config` to (1) ensure that incoming
values can be interpreted as that type, and (2) that outgoing values are
canonicalized under that type.
In another series, we propose to extend this functionality with
`--type=color` and `--default` to replace `--get-color`.
However, we traditionally use `--color` to mean "colorize this output",
instead of "this value should be treated as a color".
Currently, `git config` does not support this kind of colorization, but
we should be careful to avoid squatting on this option too soon, so that
`git config` can support `--color` (in the traditional sense) in the
future, if that is desired.
In this patch, we support `--type=<int|bool|bool-or-int|...>` in
addition to `--int`, `--bool`, and etc. This allows the aforementioned
upcoming patch to support querying a color value with a default via
`--type=color --default=...`, without squandering `--color`.
We retain the historic behavior of complaining when multiple,
legacy-style `--<type>` flags are given, as well as extend this to
conflicting new-style `--type=<type>` flags. `--int --type=int` (and its
commutative pair) does not complain, but `--bool --type=int` (and its
commutative pair) does.
