5c633a4cbe git-push: documentation and tests for pushing only branches
Commit 098e711e caused git-push to match only branches when
considering which refs to push. This patch updates the

68d3025a80 Add xmemdupz() that duplicates a block of memory, and NUL terminates it.
A lot of places in git's code use code like:

  char *res;

  len = ... find length of an interesting segment in src ...;
  res = xmalloc(len + 1);
  memcpy(res, src, len);
  res[len] = '\0';
  return res;

A new function xmemdupz() captures the allocation, copy and NUL
termination.  Existing xstrndup() is reimplemented in terms of
this new function.

0557656930 fast-import optimization:
Now that cmd_data acts on a strbuf, make last_object stashed buffer be a
strbuf as well. On new stash, don't free the last stashed buffer, rather
swap it with the one you will stash, this way, callers of store_object can
act on static strbufs, and at some point, fast-import won't allocate new
memory for objects buffers.

e6c019d0b0 Drop strbuf's 'eof' marker, and make read_line a first class citizen.
read_line is now strbuf_getline, and is a first class citizen, it returns 0
when reading a line worked, EOF else.

The ->eof marker was used non-locally by fast-import.c, mimic the same
behaviour using a static int in "read_next_command", that now returns -1 on
EOF, and avoids to call strbuf_getline when it's in EOF state.

Also no longer automagically strbuf_release the buffer, it's counter
intuitive and breaks fast-import in a very subtle way.

Note: being at EOF implies that command_buf.len == 0.

cba8d48961 git-commit: partial commit of paths only removed from the index
Because a partial commit is meant to be a way to ignore what are
staged in the index, "git rm --cached A && git commit A" should
just record what is in A on the filesystem.  The previous patch
made the command sequence to barf, saying that A has not been
added yet.  This fixes it.

64586e75af git-commit: Allow partial commit of file removal.
When making a partial commit, git-commit uses git-ls-files with
the --error-unmatch option to expand and sanity check the user
supplied path patterns.  When any path pattern does not match
with the paths known to the index, it errors out, in order to
catch a common mistake to say "git commit Makefiel cache.h"
and end up with a commit that touches only cache.h (notice the
misspelled "Makefile").  This detection however does not work
well when the path has already been removed from the index.

If you drop a path from the index and try to commit that
partially, i.e.

	$ git rm COPYING
	$ git commit -m 'Remove COPYING' COPYING

the command complains because git does not know anything about
COPYING anymore.

This introduces a new option --with-tree to git-ls-files and
uses it in git-commit when we build a temporary index to
write a tree object for the partial commit.

When --with-tree=<tree-ish> option is specified, names from the
given tree are added to the set of names the index knows about,
so we can treat COPYING file in the example as known.

Of course, there is no reason to use "git rm" and git-aware
people have long time done:

	$ rm COPYING
	$ git commit -m 'Remove COPYING' COPYING

which works just fine.  But this caused a constant confusion.

be510cfef3 send-email: make message-id generation a bit more robust
Earlier code took Unix time and appended a few random digits.
If you are firing off many messages within a second, you could
issue the same id to different messages, which is a no-no.  If
you send out 31 messages within a single second, with random
integer taken out of rand(4200), you have about 10% chance of
producing the same message ID.

This fixes the problem by uses a prefix string which is
constant-per-invocation (time and pid), with a serial number for
each message generated by the process appended at the end.

d7416ecac8 git-apply: fix whitespace stripping
The algorithm isn't right here: it accumulates any set of 8 spaces into
tabs even if they're separated by tabs, so

	<four spaces><tab><four spaces><tab>

is converted to

	<tab><tab><tab>

when it should be just

	<tab><tab>

So teach git-apply that a tab hides any group of less than 8 previous
spaces in a row.

3849bfba84 git-gui: Disable native platform text selection in "lists"
Sometimes we use a Tk text widget as though it were a listbox.
This happens typically when we want to show an icon to the left
of the text label or just when a text widget is generally a better
choice then the native listbox widget.

In these cases if we want the user to have control over the selection
we implement our own "in_sel" tag that shows the selected region
and we perform our own selection management in the background
via keybindings and mouse bindings.  In such uses we don't want
the user to be able to activate the native platform selection by
dragging their mouse through the text widget.  Doing so creates a
very confusing display and the user is left wondering what it may
mean to have two different types of selection in the same widget.

Tk doesn't allow us to delete the "sel" tag that it uses internally
to manage the native selection but it will allow us to make it
invisible by setting the tag to have the same display properties
as unselected text.  So long as we don't actually use the "sel"
tag for anything in code its effectively invisible.

ece7b74903 apply --index-info: fall back to current index for mode changes
"git diff" does not record index lines for pure mode changes (i.e. no
lines changed).  Therefore, apply --index-info would call out a bogus
error.

Instead, fall back to reading the info from the current index.

Incidentally, this fixes an error where git-rebase would not rebase a
commit including a pure mode change, and changes requiring a threeway
merge.

Noticed and later tested by Chris Shoemaker.

5ecd293d14 Rewrite convert_to_{git,working_tree} to use strbuf's.
* Now, those functions take an "out" strbuf argument, where they store their
  result if any. In that case, it also returns 1, else it returns 0.
* those functions support "in place" editing, in the sense that it's OK to
  call them this way:
    convert_to_git(path, sb->buf, sb->len, sb);
  When doable, conversions are done in place for real, else the strbuf
  content is just replaced with the new one, transparentely for the caller.

If you want to create a new filter working this way, being the accumulation
of filter1, filter2, ... filtern, then your meta_filter would be:

    int meta_filter(..., const char *src, size_t len, struct strbuf *sb)
    {
        int ret = 0;
        ret |= filter1(...., src, len, sb);
        if (ret) {
            src = sb->buf;
            len = sb->len;
        }
        ret |= filter2(...., src, len, sb);
        if (ret) {
            src = sb->buf;
            len = sb->len;
        }
        ....
        return ret | filtern(..., src, len, sb);
    }

That's why subfilters the convert_to_* functions called were also rewritten
to work this way.

40dac517ee documentation: replace Discussion section by link to user-manual chapter
The "Discussion" section has a lot of useful information, but is a
little wordy, especially for an already-long man page, and is designed
for an audience more of potential git hackers than users, which probably
doesn't make as much sense as git matures.  Also, I (perhaps foolishly)
forked a version in the user manual, which has been significantly
rewritten in an attempt to address some of the above problems.

So, remove this section and replace it by a (very terse) summary of the
original material--my attempt at the World's Shortest Git Overview--and
a reference to the appropriate chapter of the user manual.  It's
unfortunate to remove something that's been in this place for a long
time, as some people may still depend on finding it there.  But I think
we'll want to do this some day anyway.
