The code to pick up and execute command alias definition from the
configuration used to switch to the top of the working tree and
then come back when the expanded alias was executed, which was
unnecessarilyl complex. Attempt to simplify the logic by using the
early-config mechanism that does not chdir around.
* js/alias-early-config:
alias: use the early config machinery to expand aliases
t7006: demonstrate a problem with aliases in subdirectories
t1308: relax the test verifying that empty alias values are disallowed
help: use early config when autocorrecting aliases
config: report correct line number upon error
discover_git_directory(): avoid setting invalid git_dir
We are about to change the way aliases are expanded, to use the early
config machinery.
This machinery reports errors in a slightly different manner than the
cached config machinery.
Let's not get hung up by the precise wording of the message mentioning
the line number. It is really sufficient to verify that all the relevant
information is given to the user.

When fopen() returns NULL, it could be because the given path does not
exist, but it could also be some other errors and the caller has to
check. Add a wrapper so we don't have to repeat the same error check
everywhere.

In many places, Git warns about an inaccessible file after a fopen()
failed. To discern these cases from other cases where we want to warn
about inaccessible files, introduce a new helper specifically to test
whether fopen() failed because the current user lacks the permission to
open file in question.

This variable is added [1] with the assumption that on a sane system,
fopen(<dir>, "r") should return NULL. Linux and FreeBSD do not meet this
expectation while at least Windows and AIX do. Let's make sure they
behave the same way.
I only tested one version on Linux (4.7.0 with glibc 2.22) and
FreeBSD (11.0) but since GNU/kFreeBSD is fbsd kernel with gnu userspace,
I'm pretty sure it shares the same problem.

Many tests want to run a command outside of any git repo;
with the nongit() function this is now a one-liner. It saves
a few lines, but more importantly, it's immediately obvious
what the code is trying to accomplish.
This doesn't convert every such case in the test suite; it
just covers those that want to do a one-off command. Other
cases, such as the ones in t4035, are part of a larger
scheme of outside-repo files, and it's less confusing for
them to stay consistent with the surrounding tests.

When we tried to fix in 58461bd (t1308: do not get fooled by symbolic
links to the source tree, 2016-06-02) an obscure case where the user
cd's into Git's source code via a symbolic link, a regression was
introduced that affects all test runs on Windows.
The original patch introducing the test case in question was careful to
use `$(pwd)` instead of `$PWD`.
This was done to account for the fact that Git's test suite uses shell
scripting even on Windows, where the shell's Unix-y paths are
incompatible with the main Git executable's idea of paths: it only
accepts Windows paths.
It is an awkward but necessary thing, then, to use `$(pwd)` (which gives
us a Windows path) when interacting with the Git executable and `$PWD`
(which gives the shell's idea of the current working directory in Unix-y
form) for shell scripts, including the test suite itself.
Obviously this broke the use case of the Git maintainer when changing
the working directory into Git's source code directory via a symlink,
i.e. when `$(pwd)` does not agree with `$PWD`.
However, we must not fix that use case at the expense of regressing
another use case.
Let's special-case Windows here, even if it is ugly, for lack of a more
elegant solution.

t4153: fix negated test_i18ngrep call
t9003: become resilient to GETTEXT_POISON
tests: unpack-trees: update to use test_i18n* functions
...
The test functions test_i18ncmp and test_i18ngrep pretend success if run
under GETTEXT_POISON. By using those functions to test output which is
correctly marked as translatable, enables one to detect if the strings
newly marked for translation are from plumbing output. If they are
indeed from plumbing, the test would fail, and the string should be
unmarked, since it is not seen by users.
Thus, it is productive to not have false positives when running the test
under GETTEXT_POISON. This commit replaces normal test functions by
their i18n aware variants in use-cases know to be correctly marked for
translation, suppressing false positives.

When your $PWD does not match $(/bin/pwd), e.g. you have your copy
of the git source tree in one place, point it with a symbolic link,
and then "cd" to that symbolic link before running 'make test', one
of the tests in t1308 expects that the per-user configuration was
reported to have been read from the true path (i.e. relative to the
target of such a symbolic link), but the test-config program reports
a path relative to $PWD (i.e. the symbolic link).
Instead, expect a path relative to $HOME (aka $TRASH_DIRECTORY), as
per-user configuration is read from $HOME/.gitconfig and the test
framework sets these shell variables up in such a way to avoid this
problem.

A config callback passed to git_config() doesn't know very
much about the context in which it sees a variable. It can
ask whether the variable comes from a file, and get the file
name. But without analyzing the filename (which is hard to
do accurately), it cannot tell whether it is in system-level
config, user-level config, or repo-specific config.
Generally this doesn't matter; the point of not passing this
to the callback is that it should treat the config the same
no matter where it comes from. But some programs, like
upload-pack, are a special case: we should be able to run
them in an untrusted repository, which means we cannot use
any "dangerous" config from the repository config file (but
it is OK to use it from system or user config).
This patch teaches the config code to record the "scope" of
each variable, and make it available inside config
callbacks, similar to how we give access to the filename.
The scope is the starting source for a particular parsing
operation, and remains the same even if we include other
files (so a .git/config which includes another file will
remain CONFIG_SCOPE_REPO, as it would be similarly
untrusted).

When 473166b (config: add 'origin_type' to config_source
struct, 2016-02-19) added accessor functions for the origin
type and name, it taught them only to look at the "cf"
struct that is filled in while we are parsing the config.
This is sufficient to make it work with git-config, which
uses git_config_with_options() under the hood. That function
freshly parses the config files and triggers the callback
when it parses each key.
Most git programs, however, use git_config(). This interface
will populate a cache during the actual parse, and then
serve values from the cache. Calling current_config_filename()
in a callback here will find a NULL cf and produce an error.
There are no such callers right now, but let's prepare for
adding some by making this work.
We already record source information in a struct attached to
each value. We just need to make it globally available and
then consult it from the accessor functions.
