1c097891e4 user-manual: rewrite index discussion
Add an example using git-ls-files, standardize on the new "index"
terminology (as opposed to "cache"), attempt to clarify discussion and
make it a little shorter, avoid some unnecessary jargon ("write-back
cache").

971aa71fc6 user-manual: adjust section levels in "git internals"
The descriptions of the various object types should all be a subsection
of the "Object Database" section.

I cribbed most of this chapter from the README (now core-intro.txt and
git(7)), because there's stuff in there people need to know and I was
too lazy to rewrite it.  The audience isn't quite right, though--the
chapter is a mixture of user- and developer- level documentation that
isn't as appropriate now as it was originally.

So, reserve this chapter for stuff users need to know, and move the
source code introduction into a new "git hacking" chapter where we'll
also move any hacker-only technical details.

023756f4eb revision walker: --cherry-pick is a limited operation
We used to rely on the fact that cherry-pick would trigger the code path
to set limited = 1 in handle_commit(), when an uninteresting commit was
encountered.

However, when cherry picking between two independent branches, i.e. when
there are no merge bases, and there is only linear development (which can
happen when you cvsimport a fork of a project), no uninteresting commit
will be encountered.

So set limited = 1 when --cherry-pick was asked for.

db33af0a7f 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

just record what is in A on the filesystem.  The previous patch

d99ebf0817 Split grep arguments in a way that does not requires to add /dev/null.
In order to (almost) always show the name of the file without
relying on "-H" option of GNU grep, we used to add /dev/null to
the argument list unless we are doing -l or -L.  This caused
"/dev/null:0" to show up when -c is given in the output.

It is not enough to add -c to the set of options we do not pass
/dev/null for.  When we have too many files, we invoke grep
multiple times and we need to avoid giving a widow filename to
the last invocation -- otherwise we will not see the name.

This keeps two filenames when the argv[] buffer is about to
overflow and we have not finished iterating over the index, so
that the last round will always have at least two paths to work
with (and not require /dev/null).

An obvious and the only exception is when there is only 1 file
that is given to the underlying grep, and in that case we avoid
passing /dev/null and let the external "grep -c" report only the
number of matches.

Linus Torvalds
0024a54923 Fix the rename detection limit checking
This adds more proper rename detection limits. Instead of just checking
the limit against the number of potential rename destinations, we verify
that the rename matrix (which is what really matters) doesn't grow
ridiculously large, and we also make sure that we don't overflow when
doing the matrix size calculation.

This also changes the default limits from unlimited, to a rename matrix
that is limited to 100 entries on a side. You can raise it with the config
entry, or by using the "-l<n>" command line flag, but at least the default
is now a sane number that avoids spending lots of time (and memory) in
situations that likely don't merit it.

The choice of default value is of course very debatable. Limiting the
rename matrix to a 100x100 size will mean that even if you have just one
obvious rename, but you also create (or delete) 10,000 files, the rename
matrix will be so big that we disable the heuristics. Sounds reasonable to
me, but let's see if people hit this (and, perhaps more importantly,
actually *care*) in real life.

09d5dc32fb Simplify cache API
Earlier, add_file_to_index() invalidated the path in the cache-tree
but remove_file_from_cache() did not, and the user of the latter
needed to invalidate the entry himself.  This led to a few bugs due to
missed invalidate calls already.  This patch makes the management of
cache-tree less error prone by making more invalidate calls from lower
level cache API functions.

The rules are:

 - If you are going to write the index, you should either maintain
   cache_tree correctly.

   - If you cannot, alternatively you can remove the entire cache_tree
     by calling cache_tree_free() before you call write_cache().

   - When you modify the index, cache_tree_invalidate_path() should be
     called with the path you are modifying, to discard the entry from
     the cache-tree structure.

 - The following cache API functions exported from read-cache.c (and
   the macro whose names have "cache" instead of "index")
   automatically call cache_tree_invalidate_path() for you:

   - remove_file_from_index();
   - add_file_to_index();
   - add_index_entry();

   You can modify the index bypassing the above API functions
   (e.g. find an existing cache entry from the index and modify it in
   place).  You need to call cache_tree_invalidate_path() yourself in
   such a case.

042f53c569 git-gui: Provide 'uninstall' Makefile target to undo an installation
Several users have requested a "make uninstall" target be provided
in the stock git-gui Makefile so that they can undo an install
if git-gui goes to the wrong place during the initial install,
or if they are unhappy with the tool and want to remove it from
their system.

We currently assume that the complete set of files we need to delete
are those defined by our Makefile and current source directory.
This could differ from what the user actually has installed if they
installed one version then attempt to use another to perform the
uninstall.  Right now I'm just going to say that is "pilot error".
Users should uninstall git-gui using the same version of source
that they used to make the installation.  Perhaps in the future we
could read tclIndex and base our uninstall decisions on its contents.

afe2098ddd git-gui: Font chooser to handle a large number of font families
Simon Sasburg noticed that on X11 if there are more fonts than can
fit in the height of the screen Tk's native tk_optionMenu does not
offer scroll arrows to the user and it is not possible to review
all choices or to select those that are off-screen.  On Mac OS X
the tk_optionMenu works properly but is awkward to navigate if the
list is long.

This is a rewrite of our font selection by providing a new modal
dialog that the user can launch from the git-gui Options panel.
The dialog offers the user a scrolling list of fonts in a pane.
An example text shows the user what the font looks like at the size
they have selected.  But I have to admit the example pane is less
than ideal.  For example in the case of our diff font we really
should show the user an example diff complete with our native diff
syntax coloring.

80bffaf7fb 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.

0e5a7faa3a Make "git reset" a builtin.
This replaces the script "git-reset.sh" with "builtin-reset.c".

A few git commands used in the script are called from the builtin also:
"ls-files" to check for unmerged files, "read-tree" for resetting
the index file in "mixed" and "hard" resets, and "update-index" to
refresh at the end in the "mixed" reset and also for the option that
gets selected paths into the index.

The reset option with paths was implemented by Johannes Schindelin.

Since the option that gets selected paths into the index is not
a "reset" like the others because it does not change the HEAD at all,
now the command is showing a warning when the "--mixed" option
is supplied for that purpose.

The following table shows the behaviour of "git reset" for
the different supported options, where X means "changing"
the HEAD, index or working tree:

reset:  --soft  --mixed  --hard  -- <paths>
HEAD       X       X        X        -
index      -       X        X        X

4fb5fd5d30 git-commit: Disallow amend if it is going to produce an empty non-merge commit
Right now one can amend the last non-merge commit using a dirty index
and in the process maybe cause the last commit to have the same tree
as its parent.  In such a case one would want to discard the last commit
instead of amending it.

This reverts commit 8588452ceb.
