264b774ba6 merge-recursive: make the error-message generation an extern function
The construction of the struct unpack_trees_error_msgs was done within
git_merge_trees(), which prevented using the same messages easily from
another function.

73eb40eeaa git-merge-file --ours, --theirs
Sometimes people want their conflicting merges autoresolved by
favouring upstream changes.  The standard answer they are given is
to run "git diff --name-only | xargs git checkout MERGE_HEAD --" in
such a case.  This is to accept automerge results for the paths that
are fully resolved automatically, while taking their version of the
file in full for paths that have conflicts.

This is problematic on two counts.

One is that this is not exactly what these people want.  It discards
all changes they did on their branch for any paths that conflicted.
They usually want to salvage as much automerge result as possible in
a conflicted file, and want to take the upstream change only in the
conflicted part.

This patch teaches two new modes of operation to the lowest-lever
merge machinery, xdl_merge().  Instead of leaving the conflicted
lines from both sides enclosed in <<<, ===, and >>> markers, the
conflicts are resolved favouring our side or their side of changes.

A larger problem is that this tends to encourage a bad workflow by
allowing people to record such a mixed up half-merged result as a
full commit without auditing.  This commit does not tackle this
issue at all.  In git, we usually give long enough rope to users
with strange wishes as long as the risky features are not enabled by
default, and this is such a risky feature.

ed87465658 builtin-merge.c: call exclude_cmds() correctly.
We need to call exclude_cmds() after the loop, not during the loop, because
excluding a command from the array can change the indexes of objects in the
array.  The result is that, depending on file ordering, some commands
weren't excluded as they should have been.

b8ac923010 Add an option for using any HTTP authentication scheme, not only basic
This adds the configuration option http.authAny (overridable with
the environment variable GIT_HTTP_AUTH_ANY), for instructing curl
to allow any HTTP authentication scheme, not only basic (which
sends the password in plaintext).

When this is enabled, curl has to do double requests most of the time,
in order to discover which HTTP authentication method to use, which
lowers the performance slightly. Therefore this isn't enabled by default.

One example of another authentication scheme to use is digest, which
doesn't send the password in plaintext, but uses a challenge-response
mechanism instead. Using digest authentication in practice requires
at least curl 7.18.1, due to bugs in the digest handling in earlier
versions of curl.

c970a6fd01 Remove dead code from "git am"
Ever since the initial implementation, "git am" had kept a dead code that
never triggered due to a typo in the variable name.  Worse yet, the code,
if it weren't for the typo, would have attempted to add "[PATCH] " at the
beginning of the Subject: header when "git am" is run with its "-k"
option.  However, because "git am -k" tells mailinfo to keep such prefix
when parsing the input, the "[PATCH] " added by this dead code would have
really been unnecessary duplicate.

Embarrassing is that we kept _maintaining_ the codepath without anybody
noticing for four years.

ec7fc0b1a4 builtin-apply.c: pay attention to -p<n> when determining the name
The patch structure has def_name component that is used to validate the
sanity of a "diff --git" patch by checking pathnames that appear on the
patch header lines for consistency.  The git_header_name() function is
used to compute this out of "diff --git a/... b/..." line, but the code
always stripped one level of prefix (i.e. "a/" and "b/"), without paying
attention to -p<n> option.  Code in find_name() function that parses other
lines in the patch header (e.g. "--- a/..." and "+++ b/..." lines) however
did strip the correct number of leading paths prefixes, and the sanity
check between these computed values failed.

Teach git_header_name() to honor -p<n> option like find_name() function
does.

Found and reported by Steven J. Murdoch who also wrote tests.

Internet Explorer 8 stops at beginning of blame filling with the
following bug:

  "firstChild is null or not an object"

at this line:

  a_sha1.firstChild.data = commit.sha1.substr(0, 8);

It is (probably) caused by the fact that while a_sha1 element, which
looks like this:

  <a href=""> </a>

It has a firstChild which is a text node containing only whitespace
(single space character) in other web browsers (Firefox 3.5, Opera 10,
Google Chrome 3.0), IE8 clobbers DOM, removing trailing/leading
whitespace.

4f36627518 pack-objects: split implications of --all-progress from progress activation
Currently the --all-progress flag is used to use force progress display
during the writing object phase even if output goes to stdout which is
primarily the case during a push operation.  This has the unfortunate
side effect of forcing progress display even if stderr is not a
terminal.

Let's introduce the --all-progress-implied argument which has the same
intent except for actually forcing the activation of any progress
display.  With this, progress display will be automatically inhibited
whenever stderr is not a terminal, or full progress display will be
included otherwise.  This should let people use 'git push' within a cron
job without filling their logs with useless percentage displays.

0b624b4cee instaweb: restart server if already running
Running 'git instaweb' when an instaweb server is already running will
fail (at least when the port is the same) and overwrite the pid file
used to track the currently running server. This turns out to be
especially annoying when the user tries to stop the previously running
server with 'git instaweb --stop' and is instead greeted with an error
message because the pid file has been destroyed.

Instead of allowing a user to start two instaweb servers, stop the
currently running server first and then start the new one. This should
be fine because it was never really possible to start two instaweb
servers in the first place due to the pid file issue outlined above.

e1622bfcba Protect scripted Porcelains from GREP_OPTIONS insanity
If the user has exported the GREP_OPTIONS environment variable, the output
from "grep" and "egrep" in scripted Porcelains may be different from what
they expect.  For example, we may want to count number of matching lines,
by "grep" piped to "wc -l", and GREP_OPTIONS=-C3 will break such use.

The approach taken by this change to address this issue is to protect only
our own use of grep/egrep.  Because we do not unset it at the beginning of
our scripts, hook scripts run from the scripted Porcelains are exposed to
the same insanity this environment variable causes when grep/egrep is used
to implement logic (e.g. "grep | wc -l"), and it is entirely up to the
hook scripts to protect themselves.

On the other hand, applypatch-msg hook may want to show offending words in
the proposed commit log message using grep to the end user, and the user
might want to set GREP_OPTIONS=--color to paint the match more visibly.
The approach to protect only our own use without unsetting the environment
variable globally will allow this use case.

7b1042292d mergetool--lib: simplify guess_merge_tool()
Use a case statement instead of calling grep to find out if the editor's
name contains the string "vim".  Remove the check for emacs, as this
branch did the same as the default one anyway.
