With this patch applied, if any dependencies are missing, then
make clean
make COMPUTE_HEADER_DEPENDENCIES=YesPlease

Because of new commands like git-remote-http, the OBJECTS list
contains fictitious objects such as remote-http.o. Thus any
out-of-tree rules that require all $(OBJECTS) to be buildable
are broken. Add a list of real program objects to avoid this
problem.
To avoid duplication of effort, calculate the command list in
the PROGRAMS variable using the expansion of PROGRAM_OBJS.
This calculation occurs at the time $(PROGRAMS) is expanded,
so later additions to PROGRAM_OBJS will be reflected in it,
provided they occur before the build rules begin on line 1489.

Every competent shell programmer knows that a <$word in redirection is not
subject to field splitting (POSIX.1 "2.7 Redirection" explicitly lists the
kind of expansion performed: "... the word that follows the redirection
operator shall be subjected to ...", and "Field Splitting" is not among
them).

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.

Use the gcc -MMD -MP -MF options to generate dependency rules as
a byproduct when building .o files if the
COMPUTE_HEADER_DEPENDENCIES variable is defined. That variable
is left undefined by default for now.
As each object file is built, write a makefile fragment
containing its dependencies in the deps/ subdirectory of its
containing directory. The deps/ directories should be generated
if they are missing at the start of each build. So let each
object file depend on $(missing_dep_dirs), which lists only the
directories of this kind that are missing to avoid needlessly
regenerating files when the directories' timestamps change.
gcc learned the -MMD -MP -MF options in version 3.0, so most gcc
users should have them by now.
The dependencies this option computes are more specific than the
rough estimates hard-coded in the Makefile, greatly speeding up
rebuilds when only a little-used header file has changed.

$ make foo.o

The git makefile never uses any default implicit rules.
Unfortunately, if a prerequisite for one of the intended rules is
missing, a default rule can be used in its place:
$ make var.s
CC var.s
$ rm var.c
$ make var.o
as -o var.o var.s
Avoiding the default rules avoids this hard-to-debug behavior.
It also should speed things up a little in the normal case.
Future patches may restrict the scope of the %.o: %.c pattern.
This patch would then ensure that for targets not listed, we do
not fall back to the default rule.

Historically, any grep filter in "git log" family of commands were taken
as restricting to commits with any of the words in the commit log message.
However, the user almost always want to find commits "done by this person
on that topic". With "--all-match" option, a series of grep patterns can
be turned into a requirement that all of them must produce a match, but
that makes it impossible to ask for "done by me, on either this or that"
with:
log --author=me --committer=him --grep=this --grep=that
because it will require both "this" and "that" to appear.
Change the "header" parser of grep library to treat the headers specially,
and parse it as:
(all-match-OR (HEADER-AUTHOR me)
(HEADER-COMMITTER him)
(OR
(PATTERN this)
(PATTERN that) ) )
Even though the "log" command line parser doesn't give direct access to
the extended grep syntax to group terms with parentheses, this change will
cover the majority of the case the users would want.
This incidentally revealed that one test in t7002 was bogus. It ran:
log --author=Thor --grep=Thu --format='%s'
and expected (wrongly) "Thu" to match "Thursday" in the author/committer
date, but that would never match, as the timestamp in raw commit buffer
does not have the name of the day-of-the-week.

Teach "git grep" a new "-q" option to report the presense of a match via
its exit status without showing any output, similar to how "grep -q"
works. Internally "grep" engine already knew this "status-only" mode of
operation because it needed to grep inside log message to filter commits
when called from the "git log" machinery, and this patch only exposes it
to the command line tool.
A somewhat unfair benchmark in the Linux kernel directory shows a dramatic
improvement:

$ time ../git.git/git grep -q linux HEAD ; echo $?
real 0m0.030s

sys 0m0.004s

$ time git grep linux HEAD >/dev/null; echo $?
real 0m4.432s
user 0m4.272s

In Internet Explorer 8 (IE8) the 'blame_incremental' view, which uses
JavaScript to generate blame info using AJAX, sometimes hang at the
beginning (at 0%) of blaming, e.g. for larger files with long history
like git's own gitweb/gitweb.perl.
The error shown by JavaScript console is "Unspecified error" at char:2
of the following line in gitweb/gitweb.js:
if (xhr.readyState === 3 && xhr.status !== 200) {
Debugging it using IE8 JScript debuger shown that the error occurs
when trying to access xhr.status (xhr is XMLHttpRequest object).
Watch for xhr object shows 'Unspecified error.' as "value" of
xhr.status, and trying to access xhr.status from console throws error.
This bug is some intermittent bug, depending on XMLHttpRequest timing,
as it doesn't occur in all cases. It is probably caused by the fact
that handleResponse is called from timer (pollTimer), to work around
the fact that some browsers call onreadystatechange handler only once
for each state change, and not like required for 'blame_incremental'
as soon as new data is available from server. It looks like xhr
object is not properly initialized; still it is a bug to throw an
error when accessing xhr.status (and not use 'null' or 'undefined' as
value).
Work around this bug in IE8 by using try-catch block when accessing
xhr.status.

This shows that with the "--keep" option, changes that are both in
the work tree and the index are kept in the work tree after the
reset (but discarded in the index).
In the case of unmerged entries, we can see that "git reset --keep"
works only when the target state is the same as HEAD. And then the
work tree is not reset.
Signed-off-by: Christian Couder <chriscool@tuxfamily.org>
Signed-off-by: Junio C Hamano <gitster@pobox.com>
The purpose of this new option is to discard some of the
last commits but to keep current changes in the work tree.
The use case is when you work on something and commit
that work. And then you work on something else that touches
other files, but you don't commit it yet. Then you realize
that what you commited when you worked on the first thing
is not good or belongs to another branch.
So you want to get rid of the previous commits (at least in
the current branch) but you want to make sure that you keep
the changes you have in the work tree. And you are pretty
sure that your changes are independent from what you
previously commited, so you don't want the reset to succeed
if the previous commits changed a file that you also
changed in your work tree.
The table below shows what happens when running
"git reset --keep target" to reset the HEAD to another
commit (as a special case "target" could be the same as
HEAD).
working index HEAD target working index HEAD
----------------------------------------------------
A B C D --keep (disallowed)
A B C C --keep A C C
B B C D --keep (disallowed)
B B C C --keep B C C
In this table, A, B and C are some different states of
a file. For example the last line of the table means
that if a file is in state B in the working tree and
the index, and in a different state C in HEAD and in
the target, then "git reset --keep target" will put
the file in state B in the working tree, and in state
C in the index and in HEAD.
The following table shows what happens on unmerged entries:
working index HEAD target working index HEAD
----------------------------------------------------
X U A B --keep (disallowed)
X U A A --keep X A A
In this table X can be any state and U means an unmerged
entry.
Though the error message when "reset --keep" is disallowed
on unmerged entries is something like:
error: Entry 'file1' would be overwritten by merge. Cannot merge.
fatal: Could not reset index file to revision 'HEAD^'.
which is not very nice.
A following patch will add some test cases for "--keep".
The "--keep" option is implemented by doing a 2 way merge
between HEAD and the reset target, and if this succeeds
by doing a mixed reset to the target.
The code comes from the sequencer GSoC project, where
such an option was developed by Stephan Beyer:
git://repo.or.cz/git/sbeyer.git
(at commit 5a78908b70ceb5a4ea9fd4b82f07ceba1f019079)
But in the sequencer project the "reset" flag was set
in the "struct unpack_trees_options" passed to
"unpack_trees()". With this flag the changes in the
working tree were discarded if the file was different
between HEAD and the reset target.
