Earlier, we made --base-path to automatically forbid
user-relative paths, which was probably a mistake. This
introduces --user-path (or --user-path=path) option to control
the use of user-relative paths independently. The latter form
of the option can be used to restrict accesses to a part of each
user's home directory, similar to "public_html" some webservers
supports.
If we're invoked with --user-path=FOO option, then a URL of the
form git://~USER/PATH/... resolves to the path HOME/FOO/PATH/...,
where HOME is USER's home directory.

It _might_ make sense for certain users like gitk and gitview if
we had a single tool that gives --pretty and its diff even if
the diff is empty. Having said that, the flag --cc -m is too
specific. If some uses want to see the commit log even for an
empty diff, that flag should not be something only --cc honors.
Here's an "--always" flag that does that.

As far as I can see, create_subdirectories() in apply.c just
duplicates the functionality of safe_create_leading_directories() from
sha1_file.c. The former has a warm, fuzzy const parameter, but that's
not important.
The potential problem with EEXIST and creating directories should
never occur here, but will be removed by future
safe_create_leading_directories() changes. Other uses of EEXIST in
apply.c should be fine barring intentionally malicious behavior.

This updates the output format to make administrative lines more
consistent with the traditional diffs.
The "index" line shows blob object names from each parents
(separated by commas), double dots and the object name of the
resulting blob.
The hunk header line begins with N+1 '@' characters for N-way
diff, the line number L of the first line in the hunk and line
count C from the parent in "-L,C" format for each parents and
then the line number of the first line in the hunk and line
count from the resulting file in "+L,C" format, and finally
N+1 '@' characters (earlier versions had the line numbers from
the resulting file at the beginning).
Signed-off-by: Junio C Hamano <junkio@cox.net>
The flag on the surviving lines meant "this parent is not
different" while the parent_map flag on the lost lines meant
"this parent is different", which was confusing. So swap the
meaning of on-bit in the flag. Also more heavily comment the

Earlier logic was discarding hunks that has difference from only
one parent or the same difference from all but one parent. This
changes it to check if the differences on all lines are from the

So far, e.g. git-update-index --refresh was basically uninterruptable
by ctrl-c, since it hooked the SIGINT handler, but that handler would
only unlink the lockfile but not actually quit. This makes it propagate
the signal to the default handler.
Note that I expected it to work without resetting the signal handler to
SIG_DFL, but without that it ended in an infinite loop of tgkill()s -
is my glibc violating SUS or what?

Showing the same parent more than once for a commit does not
make much sense downstream, so stop it.
This can happen with an incorrectly made merge commit that
merges the same parent twice, but can happen in an otherwise
sane development history while squishing the history by taking
into account only commits that touch specified paths.
For example,
$ git rev-list --max-count=1 --parents addafaf -- rev-list.c
would have to show this commit ancestry graph:
.---o---.
/ \
.---*---o---.
/ 93b74bc \
---*---o---o-----o---o-----o addafafd8f6b34 \ /
.---o---o---.
\ /
.---*---.
