No need to hate it. Here comes the rebased patch, and this time, I

Do our own ctype.h, just to get the sane semantics: we want
locale-independence, _and_ we want the right signed behaviour. Plus we
only use a very small subset of ctype.h anyway (isspace, isalpha,
isdigit and isalnum).

git-http-fetch received objects/info/packs into a fixed-size buffer
and started to fail when this file became larger than the buffer.
Change it to grow the buffer dynamically, and do the same thing for

It seemed to be such a stupid syntax. It's both what "ssh://" means,
and it's what not specifying a protocol at _all_ means.

But hey, since we already have two ways of saying "use ssh with

This enhances set of revs you can give format-patch.

Originally, format-patch took either one rev, or two revs:

    format-patch rev1
    format-patch rev1 rev2

The first format was a short-hand for "format-patch rev1 HEAD"
(i.e. rev2==HEAD).  What this meant was to find commits that are
in branch rev2 that has not been merged to branch rev1.

The above notation is still supported, but now it takes sequence
of "from1..to1 from2..to2 ...".  In short, the second format has
become a short-hand for "format-patch rev1..rev2".  Commits in
to1 but not in from1, to2 but not in from2, ... are formatted as
emailable patches.

With this, cherry-picking from other branch can be written as:

    git-format-patch -k --stdout master..branch1 master..branch2 |
    git-am -k -3

which is generally faster than traditional cherry-pick (which
always did 3-way merge) if patches apply cleanly, and still
falls back on 3-way merge if some of them do not.

This uses the new "--local" flag to git-pack-objects.  It currently only
makes a difference together with "-a", since a normal incremental repack
won't pack any packed objects at all (whether local or remote).

Eventually, it might end up skipping any objects that aren't local to
the current object directory, but for now it only knows to skip packed
objects.

This adds the "--local" flag to git-pack-objects, which acts like
"--incremental", except that instead of ignoring all packed objects, it
only ignores objects that are packed and in an alternate object tree.

As a result, it effectively only does a local re-pack: any remote-packed
objects will stay in the alternate object directories.

This changes the generation of hash packfiles have in their names, from
"hash of object names as fed to us" to "hash of object names in the
resulting pack, in the order they appear in the index file".  The new
"git-index-pack" command is taught to output the computed hash value
to its standard output.

With this, we can store downloaded pack in a temporary file without
knowing its final name, run git-index-pack to generate idx for it
while finding out its final name, and then rename the pack and idx to
their final names.

"git-fetch --tags" can get confused with tags with spaces in their names,
it used to use shell IFS to split the list of tags and also used curl
which insists the URL to be escaped.  Fix it so it can work with Martin's
moodle repository http://locke.catalyst.net.nz/git/moodle.git/.

We still reserve characters like leading plus-sign '+' and colon
':' anywhere to represent refspec src-dst pair, and obviously we
cannot use LF (that terminates Pull: line in .git/remotes
files), but now you can have spaces with this patch.
Signed-off-by: NJunio C Hamano <junkio@cox.net>

curl_escape ought to do this, but we should not let it quote
slashes (nobody said refs/tags cannot have subdirectories), so
we roll our own safer version.  With this, the last part of
git-clone from Martin's moodle repository that used to fail now
works, which reads:

 $ git-http-fetch -v -a -w 'tags/MOODLE_15_MERGED **INVALID**' \

They always were meant to be case-insensitive, but I had missed one
"tolower()", making that not true.

The actual _values_ aren't case-insensitive, of course, although some uses
of them may be (ie boolean parsing uses "strcasecmp()" to match against
the strings "true" and "false").

This starts using the "user.name" and "user.email" config variables if
they exist as the default name and email when committing.  This means
that you don't have to use the GIT_COMMITTER_EMAIL environment variable
to override your email - you can just edit the config file instead.

The patch looks bigger than it is because it makes the default name and
email information non-static and renames it appropriately.  And it moves
the common git environment variables into a new library file, so that
you can link against libgit.a and get the git environment without having
to link in zlib and libcrypt.

In short, most of it is renaming and moving, the real change core is
just a few new lines in "git_default_config()" that copies the user
config values to the new base.

It also changes "git-var -l" to list the config variables.

With "[core] filemode = false", you can tell git to ignore
differences in the working tree file only in executable bit.

 * "git-update-index --refresh" does not say "needs update" if index
   entry and working tree file differs only in executable bit.

 * "git-update-index" on an existing path takes executable bit
   from the existing index entry, if the path and index entry are
   both regular files.

 * "git-diff-files" and "git-diff-index" without --cached flag
   pretend the path on the filesystem has the same executable
   bit as the existing index entry, if the path and index entry
   are both regular files.

If you are on a filesystem with unreliable mode bits, you may need to
force the executable bit after registering the path in the index.

 * "git-update-index --chmod=+x foo" flips the executable bit of the
   index file entry for path "foo" on.  Use "--chmod=-x" to flip it
   off.

Note that --chmod only works in index file and does not look at nor
update the working tree.

So if you are on a filesystem and do not have working executable bit,
you would do:

 1. set the appropriate .git/config option;

 2. "git-update-index --add new-file.c"

 3. "git-ls-files --stage new-file.c" to see if it has the desired
   mode bits.  If not, e.g. to drop executable bit picked up from the
   filesystem, say "git-update-index --chmod=-x new-file.c".

I had meant to disallow unknown escape characters in the config file
parser, but instead an unknown escaped character would silently pass
through as itself. That's correct for some cases (notably '\' itself), but
wasn't correct in general.

This fixes it, and makes the parser write a nice error message if the
config file contains bogus escaped characters.

Signed-off-by: NJunio C Hamano <junkio@cox.net>

The http commit walker cannot use the same temporary file
creation code because it needs to use predictable temporary
filename for partial fetch continuation purposes, but the code
to move the temporary file to the final location should be
usable from the ordinary object creation codepath.

Export move_temp_to_file from sha1_file.c and use it, while
losing the custom relink_or_rename function from http-fetch.c.

Also the temporary object file creation part needs to make sure
the leading path exists, in preparation of the really lazy
fan-out directory creation.

Be sure not to fetch objects that already exist in the local repository.
The main process loop no longer performs this check, http-fetch now checks
prior to starting a new request queue entry and when fetch_object() is called,
and local-fetch now checks when fetch_object() is called.

objects to transfer and starts feeding requests to an active request
queue for processing; fetch_object keeps the active queue moving
while the specified object is being transferred.  The size of the active
queue can be restricted using -r and defaults to 5 concurrent transfers.
Requests for objects that are not prefetched are also processed via the
active queue.
