f285a2d7ed Replace calls to strbuf_init(&foo, 0) with STRBUF_INIT initializer
Many call sites use strbuf_init(&foo, 0) to initialize local
strbuf variable "foo" which has not been accessed since its
declaration. These can be replaced with a static initialization
using the STRBUF_INIT macro which is just as readable, saves a
function call, and takes up fewer lines.

de056402fd config.c: Tolerate UTF8 BOM at the beginning of config file
Unfortunately, the abomination of Windows Notepad likes to scatted
non-sensical UTF8 BOM marks across text files it edits. This is
especially troublesome when editing the Git configuration file,
and it does not appear to be particularly harmful to teach Git
to deal with this poo in the configfile.

1ce4790bf5 Make use of stat.ctime configurable
A new configuration variable 'core.trustctime' is introduced to
allow ignoring st_ctime information when checking if paths
in the working tree has changed, because there are situations where
it produces too much false positives.  Like when file system crawlers
keep changing it when scanning and using the ctime for marking scanned
files.

The default is to notice ctime changes.

2de9de5e4a Move code interpreting path relative to exec-dir to new function system_path()
Expanding system paths relative to git_exec_path can be used for
creating an installation that can be moved to a different directory
without re-compiling.  We use this approach for template_dir and the
system wide gitconfig.  The Windows installer (msysgit) is an example
for such a setup.

This commit moves common code to a new function system_path().  System
paths that are to be interpreted relative to git_exec_path are passed to
system_path() and the return value is used instead of the original path.
system_path() prefixes a relative path with git_exec_path and leaves
absolute paths unmodified.  For example, we now write

    template_dir = system_path(DEFAULT_GIT_TEMPLATE_DIR);

[j6t: moved from path.c to exec_cmd.c]

dc87183189 Only use GIT_CONFIG in "git config", not other programs
For everything other than using "git config" to read or write a
git-style config file that isn't the current repo's config file,
GIT_CONFIG was actively detrimental. Rather than argue over which
programs are important enough to have work anyway, just fix all of
them at the root.

Also removes GIT_LOCAL_CONFIG, which would only be useful for programs
that do want to use global git-specific config, but not the repo's own
git-specific config, and want to use some other, presumably
git-specific config. Despite being documented, I can't find any sign that
it was ever used.

aafe9fbaf4 Add config option to enable 'fsync()' of object files
As explained in the documentation[*] this is totally useless on
filesystems that do ordered/journalled data writes, but it can be a
useful safety feature on filesystems like HFS+ that only journal the
metadata, not the actual file contents.

It defaults to off, although we could presumably in theory some day
auto-enable it on a per-filesystem basis.

9ed36cfa35 branch: optionally setup branch.*.merge from upstream local branches
"git branch" and "git checkout -b" now honor --track option even when
the upstream branch is local.  Previously --track was silently ignored
when forking from a local branch.  Also the command did not error out
when --track was explicitly asked for but the forked point specified
was not an existing branch (i.e. when there is no way to set up the
tracking configuration), but now it correctly does.

The configuration setting branch.autosetupmerge can now be set to
"always", which is equivalent to using --track from the command line.
Setting branch.autosetupmerge to "true" will retain the former behavior
of only setting up branch.*.merge for remote upstream branches.

Includes test cases for the new functionality.

ea5105a5e3 config: add 'git_config_string' to refactor string config variables.
In many places we just check if a value from the config file is not
NULL, then we duplicate it and return 0. This patch introduces the new
'git_config_string' function to do that.

This function is also used to refactor some code in 'config.c'.
Refactoring other files is left for other patches.

Also not all the code in "config.c" is refactored, because the function
takes a "const char **" as its first parameter, but in many places a
"char *" is used instead of a "const char *". (And C does not allow
using a "char **" instead of a "const char **" without a warning.)

21e5ad50fc safecrlf: Add mechanism to warn about irreversible crlf conversions
CRLF conversion bears a slight chance of corrupting data.
autocrlf=true will convert CRLF to LF during commit and LF to
CRLF during checkout.  A file that contains a mixture of LF and
CRLF before the commit cannot be recreated by git.  For text
files this is the right thing to do: it corrects line endings
such that we have only LF line endings in the repository.
But for binary files that are accidentally classified as text the
conversion can corrupt data.

If you recognize such corruption early you can easily fix it by
setting the conversion type explicitly in .gitattributes.  Right
after committing you still have the original file in your work
tree and this file is not yet corrupted.  You can explicitly tell
git that this file is binary and git will handle the file
appropriately.

Unfortunately, the desired effect of cleaning up text files with
mixed line endings and the undesired effect of corrupting binary
files cannot be distinguished.  In both cases CRLFs are removed
in an irreversible way.  For text files this is the right thing
to do because CRLFs are line endings, while for binary files
converting CRLFs corrupts data.

This patch adds a mechanism that can either warn the user about
an irreversible conversion or can even refuse to convert.  The
mechanism is controlled by the variable core.safecrlf, with the
following values:

 - false: disable safecrlf mechanism
 - warn: warn about irreversible conversions
 - true: refuse irreversible conversions

The default is to warn.  Users are only affected by this default
if core.autocrlf is set.  But the current default of git is to
leave core.autocrlf unset, so users will not see warnings unless
they deliberately chose to activate the autocrlf mechanism.

The safecrlf mechanism's details depend on the git command.  The
general principles when safecrlf is active (not false) are:

 - we warn/error out if files in the work tree can modified in an
   irreversible way without giving the user a chance to backup the
   original file.

 - for read-only operations that do not modify files in the work tree
   we do not not print annoying warnings.

There are exceptions.  Even though...

 - "git add" itself does not touch the files in the work tree, the
   next checkout would, so the safety triggers;

 - "git apply" to update a text file with a patch does touch the files
   in the work tree, but the operation is about text files and CRLF
   conversion is about fixing the line ending inconsistencies, so the
   safety does not trigger;

 - "git diff" itself does not touch the files in the work tree, it is
   often run to inspect the changes you intend to next "git add".  To
   catch potential problems early, safety triggers.

The concept of a safety check was originally proposed in a similar
way by Linus Torvalds.  Thanks to Dimitry Potapov for insisting
on getting the naked LF/autocrlf=true case right.

init-db made it relative to exec_path using prefix_path(), which
is wrong.  prefix_path() is about a file inside the work tree.
There was a similar misuse in config.c that takes relative
ETC_GITCONFIG path.

A convenience function prefix_filename() can concatenate two paths
to form a path that points at somewhere outside the work tree.
Use it in these codepaths instead.

Remove remaining double close(2)'s.  i.e. close() before
commit_locked_index() or commit_lock_file().

02e5ba4ae6 config: handle lack of newline at end of file better
The config parsing routines use the static global
'config_file' to store the FILE* pointing to the current
config file being parsed. The function get_next_char()
automatically converts an EOF on this file to a newline for
the convenience of its callers, and it sets config_file to
NULL to indicate that EOF was reached.

This throws away useful information, though, since some
routines want to call ftell on 'config_file' to find out
exactly _where_ the routine ended. In the case of a key
ending at EOF boundary, we ended up segfaulting in some
cases (changing that key or adding another key in its
section), or failing to provide the necessary newline
(adding a new section).

This patch adds a new flag to indicate EOF and uses that
instead of setting config_file to NULL. It also makes sure
to add newlines where necessary for truncated input. All
three included tests fail without the patch.

c8deb5a146 Improve error messages when int/long cannot be parsed from config
If a config file has become mildly corrupted due to a missing LF
we may discover some other option joined up against the end of a
numeric value.  For example:

	[section]
	number = 1auto

where the "auto" flag was meant to occur on the next line, below
"number", but the missing LF has caused it to no longer be its
own option.  Instead the word "auto" is parsed as a 'unit factor'
for the value of "number".

Before this change we got the confusing error message:

  fatal: unknown unit: 'auto'

which told us nothing about where the problem appeared.  Now we get:

  fatal: bad config value for 'aninvalid.unit'

which at least points the user in the right direction of where to
search for the incorrectly formatted configuration file.

Noticed by erikh on #git, which received the original error from
a simple `git checkout -b` due to a midly corrupted config.

Avoids horrible 1-byte write(2) calls and cleans up the logic a bit.
