d131b7afea sha1_file.c: Don't retain open fds on small packs
If a pack file is small enough that its entire contents fits within
one mmap window, mmap the file and then immediately close its file
descriptor.  This reduces the number of file descriptors that are
needed to read from repositories with many tiny pack files, such
as one that has received 1000 pushes (and created 1000 small pack
files) since its last repack.

b09c53a3e3 Sanity-check config variable names
Sanity-check config variable names when adding and retrieving them.  As a side
effect code duplication between git_config_set_multivar and get_value (in
builtin/config.c) was removed and the common functionality was placed in
git_config_parse_key.

This breaks a test in t1300 which used invalid section-less keys in the tests
for "git -c". However, allowing such names there was useless, since there was
no way to set them via config file, and no part of git actually tried to use
section-less keys. This patch updates the test to use more realistic examples
as well as adding its own test.

53c403116a push.default: Rename 'tracking' to 'upstream'
Users are sometimes confused with two different types of "tracking" behavior
in Git: "remote-tracking" branches (e.g. refs/remotes/*/*) versus the
merge/rebase relationship between a local branch and its @{upstream}
(controlled by branch.foo.remote and branch.foo.merge config settings).

When the push.default is set to 'tracking', it specifies that a branch should
be pushed to its @{upstream} branch. In other words, setting push.default to
'tracking' applies only to the latter of the above two types of "tracking"
behavior.

In order to make this more understandable to the user, we rename the
push.default == 'tracking' option to push.default == 'upstream'.

push.default == 'tracking' is left as a deprecated synonym for 'upstream'.

dab0d4108d correct type of EMPTY_TREE_SHA1_BIN
Functions such as hashcmp that expect a binary SHA-1 value take
parameters of type "unsigned char *" to avoid accepting a textual
SHA-1 passed by mistake.  Unfortunately, this means passing the string
literal EMPTY_TREE_SHA1_BIN requires an ugly cast.  Tweak the
definition of EMPTY_TREE_SHA1_BIN to produce a value of more
convenient type.

In the future the definition might change to

	extern const unsigned char empty_tree_sha1_bin[20];
	#define EMPTY_TREE_SHA1_BIN empty_tree_sha1_bin

c879daa237 Make hash-object more robust against malformed objects
Commits, trees and tags have structure. Don't let users feed git
with malformed ones. Sooner or later git will die() when
encountering them.

Note that this patch does not check semantics. A tree that points
to non-existent objects is perfectly OK (and should be so, users
may choose to add commit first, then its associated tree for example).

bc96cc87db tree_entry_interesting(): support depth limit
This is needed to replace pathspec_matches() in builtin/grep.c.

max_depth == -1 means infinite depth. Depth limit is only effective
when pathspec.recursive == 1. When pathspec.recursive == 0, the
behavior depends on match functions: non-recursive for
tree_entry_interesting() and recursive for match_pathspec{,_depth}

0602f3e916 Add struct pathspec
The old pathspec structure remains as pathspec.raw[]. New things are
stored in pathspec.items[]. There's no guarantee that the pathspec
order in raw[] is exactly as in items[].

raw[] is external (source) data and is untouched by pathspec
manipulation functions. It eases migration from old const char ** to
this new struct.

e6aea2dba2 setup: limit get_git_work_tree()'s to explicit setup case only
get_git_work_tree() takes input as core.worktree, core.bare,
GIT_WORK_TREE and decides correct worktree setting.

Unfortunately it does not do its job well. core.worktree and
GIT_WORK_TREE should only be taken into account, if GIT_DIR is set
(which is handled by setup_explicit_git_dir). For other setup cases,
only core.bare matters.

Add a temporary variable setup_explicit to adjust get_git_work_tree()
behavior as such. This variable will be gone once setup_* rework is
done.

Also remove is_bare_repository_cfg check in set_git_work_tree() to
ease the rework. We are going to check for core.bare and core.worktree
early before setting worktree. For example, if core.bare is true, no
need to set worktree.

f07d6a1ad1 setup: save prefix (original cwd relative to toplevel) in startup_info
Save the path from the original cwd to the cwd at the end of the
setup procedure in the startup_info struct introduced in e37c1329
(2010-08-05).  The value cannot vary from thread to thread anyway,
since the cwd is global.

So now in your builtin command, instead of passing prefix around,
when you want to convert a user-supplied path to a cwd-relative
path, you can use startup_info->prefix directly.

Caveat: As with the return value from setup_git_directory_gently(),
startup_info->prefix would be NULL when the original cwd is not a
subdir of the toplevel.

Longer term, this would allow the prefix to be reused when several
noncooperating functions require access to the same repository (for
example, when accessing configuration before running a builtin).

f4b05a4947 Make the tab width used for whitespace checks configurable
A new whitespace "rule" is added that sets the tab width to use for
whitespace checks and fix-ups and replaces the hard-coded constant 8.

Since the setting is part of the rules, it can be set per file using
.gitattributes.

The new configuration is backwards compatible because older git versions
simply ignore unknown whitespace rules.

2431afbf1b unpack-trees: move all skip-worktree checks back to unpack_trees()
Earlier, the will_have_skip_worktree() checks are done in various
places, which makes it hard to traverse the index tree-alike, required
by excluded_from_list(). This patch moves all the checks into two
loops in unpack_trees().

Entries in index in this operation can be classified into two
groups: ones already in index before unpack_trees() is called and ones
added to index after traverse_trees() is called.

In both groups, before checking file status on worktree, the future
skip-worktree bit must be checked, so that if an entry will be outside
worktree, worktree should not be checked.

For the first group, the future skip-worktree bit is precomputed and
stored as CE_NEW_SKIP_WORKTREE in the first loop before
traverse_trees() is called so that *way_merge() function does not need
to compute it again.

For the second group, because we don't know what entries will be in
this group until traverse_trees() finishes, operations that need
future skip-worktree check is delayed until CE_NEW_SKIP_WORKTREE is
computed in the second loop. CE_ADDED is used to mark entries in the
second group.

CE_ADDED and CE_NEW_SKIP_WORKTREE are temporary flags used in
unpack_trees().  CE_ADDED is only used by add_to_index(), which should
not be called while unpack_trees() is running.

b90d9b8895 work around buggy S_ISxxx(m) implementations
There are buggy implementations of S_ISxxx(m) macros on some platforms
(e.g. NetBSD).  The issue is that NetBSD doesn't take care to wrap its
macro arguments in parentheses, so on Linux and sane systems we have
S_ISREG(m) defined as something like:

    (((m) & S_IFMT) == S_IFREG)

But on NetBSD:

    ((m & _S_IFMT) == _S_IFREG)

Since a caller in builtin/diff.c called our macro as `S_IFREG | 0644'
this bug introduced a logic error on NetBSD, since the precedence of
bit-wise & is higher than | in C.

2b64fc894d pass "git -c foo=bar" params through environment
Git uses the "-c foo=bar" parameters to set a config
variable for a single git invocation. We currently do this
by making a list in the current process and consulting that
list in git_config.

This works fine for built-ins, but the config changes are
silently ignored by subprocesses, including dashed externals
and invocations to "git config" from shell scripts.

This patch instead puts them in an environment variable
which we consult when looking at config (both internally and
via calls "git config").

a60645f9c5 setup: remember whether repository was found
As v1.7.2~16^2 (git --paginate: paginate external commands
again, 2010-07-14) explains, builtins (like git config) that
do not use RUN_SETUP are not finding GIT_DIR set correctly when
it is time to launch the pager from run_builtin().  If they
were to search for a repository sooner, then the outcome of such
early repository accesses would be more predictable and reliable.

The cmd_*() functions learn whether a repository was found through the
*nongit_ok return value from setup_git_directory_gently().  If
run_builtin() is to take care of the repository search itself, that
datum needs to be retrievable from somewhere else.  Use the
startup_info struct for this.

As a bonus, this information becomes available to functions such as
git_config() which might want to avoid trying to access a repository
when none is present.

e37c1329fa git wrapper: introduce startup_info struct
The startup_info struct will collect information managed by the git
setup code, such as the prefix for relative paths passed on the
command line (i.e., path to the starting cwd from the toplevel of
the work tree) and whether a git repository has been found.

In other words, startup_info is intended to be a collection of global
variables with results that were previously returned from setup
functions.  This state is global anyway (since the cwd is), even
if it is not currently tracked that way.  Letting these values persist
means there is more flexibility in deciding when to run setup.

For now, the struct is empty.

700e66d661 unpack-trees: let read-tree -u remove index entries outside sparse area
To avoid touching the worktree outside a sparse checkout,
when the update flag is enabled unpack_trees() clears the
CE_UPDATE and CE_REMOVE flags on entries that do not match the
sparse pattern before actually committing any updates to the
index file or worktree.

The effect on the index was unintentional; sparse checkout was
never meant to prevent index updates outside the area checked
out.  And the result is very confusing: for example, after a
failed merge, currently "git reset --hard" does not reset the
state completely but an additional "git reset --mixed" will.

So stop clearing the CE_REMOVE flag.  Instead, maintain a
CE_WT_REMOVE flag to separately track whether a particular
file removal should apply to the worktree in addition to the
index or not.

The CE_WT_REMOVE flag is used already to mark files that
should be removed because of a narrowing checkout area.  That
usage will still apply; do not clear the CE_WT_REMOVE flag
in that case (detectable because the CE_REMOVE flag is not
set).

This bug masked some other bugs illustrated by the test
suite, which will be addressed by later patches.

7610fa57e6 merge-recursive --renormalize
Teach "git merge-recursive" a --renormalize option to enable the
merge.renormalize configuration.  The --no-renormalize option can
be used to override it in the negative.

So in the future, you might be able to, e.g.:

	git checkout -m -Xrenormalize otherbranch

or

	git revert -Xrenormalize otherpatch

or

	git pull --rebase -Xrenormalize

The bad part: merge.renormalize is still not honored for most
commands.  And it reveals lots of places that -X has not been plumbed
in (so we get "git merge -Xrenormalize" but not much else).

9644c06163 Export parse_date_basic() to convert a date string to timestamp
approxidate() is not appropriate for reading machine-written dates
because it guesses instead of erroring out on malformed dates.
parse_date() is less convenient since it returns its output as a
string.  So export the underlying function that writes a timestamp.

While at it, change the return value to match the usual convention:
return 0 for success and -1 for failure.

f217f0e86d Avoid conflicts when merging branches with mixed normalization
Currently, merging across changes in line ending normalization is
painful since files containing CRLF will conflict with normalized files,
even if the only difference between the two versions is the line
endings.  Additionally, any "real" merge conflicts that exist are
obscured because every line in the file has a conflict.

Assume you start out with a repo that has a lot of text files with CRLF
checked in (A):

      o---C
     /     \
    A---B---D

B: Add "* text=auto" to .gitattributes and normalize all files to
   LF-only

C: Modify some of the text files

D: Try to merge C

You will get a ridiculous number of LF/CRLF conflicts when trying to
merge C into D, since the repository contents for C are "wrong" wrt the
new .gitattributes file.

Fix ll-merge so that the "base", "theirs" and "ours" stages are passed
through convert_to_worktree() and convert_to_git() before a three-way
merge.  This ensures that all three stages are normalized in the same
way, removing from consideration differences that are only due to
normalization.

This feature is optional for now since it changes a low-level mechanism
and is not necessary for the majority of users.  The "merge.renormalize"
config variable enables it.

4b05548fc0 enums: omit trailing comma for portability
Without this patch at least IBM VisualAge C 5.0 (I have 5.0.2) on AIX
5.1 fails to compile git.

enum style is inconsistent already, with some enums declared on one
line, some over 3 lines with the enum values all on the middle line,
sometimes with 1 enum value per line... and independently of that the
trailing comma is sometimes present and other times absent, often
mixing with/without trailing comma styles in a single file, and
sometimes in consecutive enum declarations.

Clearly, omitting the comma is the more portable style, and this patch
changes all enum declarations to use the portable omitted dangling
comma style consistently.

Change the semantics of the "crlf" attribute so that it enables
end-of-line normalization when it is set, regardless of "core.autocrlf".

Add a new setting for "crlf": "auto", which enables end-of-line
conversion but does not override the automatic text file detection.

Add a new attribute "eol" with possible values "crlf" and "lf".  When
set, this attribute enables normalization and forces git to use CRLF or
LF line endings in the working directory, respectively.

The line ending style to be used for normalized text files in the
working directory is set using "core.autocrlf".  When it is set to
"true", CRLFs are used in the working directory; when set to "input" or
"false", LFs are used.

7b64469a36 Allow parse_pack_index on temporary files
The easiest way to verify a pack index is to open it through the
standard parse_pack_index function, permitting the header check
to happen when the file is mapped.  However, the dumb HTTP client
needs to verify a pack index before its moved into its proper file
name within the objects/pack directory, to prevent a corrupt index
from being made available.  So permit the caller to specify the
exact path of the index file.

For now we're still using the final destination name within the
sole call site in http.c, but eventually we will start to parse
the temporary path instead.

Otherwise, the code is unchanged. There are still a few

f206063b4b git-core: Support retrieving passwords with GIT_ASKPASS
git tries to read a password from the terminal in imap-send and
when talking to a http server that requires authentication.

When a GUI is driving git, however, the end user is not paying
attention to the terminal (there may not even be a terminal).
GUI would appear to hang forever.

Fix this problem by allowing a password-retrieving command
to be specified in GIT_ASKPASS

48a7c1c49d Refactor list of of repo-local env vars
Move the list of GIT_* environment variables that are local to a
repository into a static list in environment.c, as it is also
useful elsewhere. Also add the missing GIT_CONFIG variable to the
list.

Make it easy to use the list both by NULL-termination and by size;
the latter (excluding the terminating NULL) is stored in the
local_repo_env_size define.

b862b61c03 git_mkstemp_mode, xmkstemp_mode: variants of gitmkstemps with mode argument.
gitmkstemps emulates the behavior of mkstemps, which is usually used
to create files in a shared directory like /tmp/, hence, it creates
files with permission 0600.

Add git_mkstemps_mode() that allows us to specify the desired mode, and
make git_mkstemps() a wrapper that always uses 0600 to call it. Later we
will use git_mkstemps_mode() when creating pack files.

8420ccd8b8 git_config_maybe_bool()
Some configuration variables can take boolean values in addition to
enumeration specific to them.  Introduce git_config_maybe_bool() that
returns 0 or 1 if the given value is boolean, or -1 if not, so that
a parser for such a variable can check for boolean first and then
parse other kinds of values as a fallback.

64778d24a9 Make 'git var GIT_PAGER' always print the configured pager
Scripted commands that want to use git’s configured pager know better
than ‘git var’ does whether stdout is going to be a tty at the
appropriate time.  Checking isatty(1) as git_pager() does now won’t
cut it, since the output of git var itself is almost never a terminal.
The symptom is that when used by humans, ‘git var GIT_PAGER’ behaves
as it should, but when used by scripts, it always returns ‘cat’!

So avoid tricks with isatty() and just always print the configured
pager.

This does not fix the callers to check isatty(1) themselves yet.
Nevertheless, this patch alone is enough to fix 'am --interactive'.

Thanks to Sebastian Celis for the report and Jeff King for the
analysis.

93cfa7c7a8 approxidate_careful() reports errorneous date string
For a long time, the time based reflog syntax (e.g. master@{yesterday})
didn't complain when the "human readable" timestamp was misspelled, as
the underlying mechanism tried to be as lenient as possible.  The funny
thing was that parsing of "@{now}" even relied on the fact that anything
not recognized by the machinery returned the current timestamp.

Introduce approxidate_careful() that takes an optional pointer to an
integer, that gets assigned 1 when the input does not make sense as a
timestamp.

As I am too lazy to fix all the callers that use approxidate(), most of
the callers do not take advantage of the error checking, but convert the
code to parse reflog to use it as a demonstration.

Tests are mostly from Jeff King.
