Avoid multiple PREFIX definitionsPhilip Oakley Sat, 21 Apr 2018 11:18:42 +0000 (13:18 +0200)

Avoid multiple PREFIX definitions

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:

sed: 1: "s=@@INSTLIBDIR@@=/usr/l ...": unescaped newline inside substitute pattern

Add back the missing double-quotes to make it work again.

walker: drop fields of `struct walker` which are always 1

After the previous commit, both users of `struct walker` set `get_tree`,
`get_history` and `get_all` to 1. Drop those fields and simplify the
walker implementation accordingly.

Let's hope that any out-of-tree users will not mind this change. They
should notice that the compilation fails as they try to set these
fields. (If they do not set them, note that `get_http_walker()` leaves
them undefined, so the behavior will have been undefined all the time.)

http-fetch: make `-a` standard behaviourMartin Ågren Sun, 22 Apr 2018 18:12:49 +0000 (20:12 +0200)

http-fetch: make `-a` standard behaviour

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.)

push: colorize errorsRyan Dammrose Sat, 21 Apr 2018 10:10:00 +0000 (12:10 +0200)

push: colorize errors

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.

[jes: fixed a couple bugs, added the color.{advice,push,transport}
settings, refactored to use want_color_stderr().]

color: introduce support for colorizing stderr

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.

builtin/config: introduce `color` type specifier

As of this commit, the canonical way to retreive an ANSI-compatible
color escape sequence from a configuration file is with the
`--get-color` action.

This is to allow Git to "fall back" on a default value for the color
should the given section not exist in the specified configuration(s).

With the addition of `--default`, this is no longer needed since:

$ git config --default red --type=color core.section

will be have exactly as:

$ git config --get-color core.section red

For consistency, let's introduce `--type=color` and encourage its use
with `--default` together over `--get-color` alone.
