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.

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.

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.

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.

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.

if git-gui goes to the wrong place during the initial install,

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.

a4503a15af Make --no-thin the default in git-push to save server resources
1) pushes happen less often than fetches, so the bandwidth saving is
   much less visible in that case overall.

2) thin packs have to be complemented with missing delta bases to be
   valid, so many received thin packs will take more disk space.

3) the bother of repacking should be distributed amongst "clients"
   i.e. fetchers and pushers as much as possible, and not the server
   being fetched or pushed, to keep disk and CPU usage low on the
   server.

This is why a fetch should get thin packs but a push should not.

Both Nico and I have been assuming that --no-thin was the default
behavior of git-push ever since Nico introduced --fix-thin into the
index-pack process, which allowed fetch and receive-pack to avoid
exploding packfiles received during transfer.  This patch finally
makes it so.

aba91192ae git-tag -s must fail if gpg cannot sign the tag.
Most of this patch code and message was written by Shawn O. Pearce.
I made some tests to know what the problem was, and then I changed
the code related with the SIGPIPE signal.

If the user has misconfigured `user.signingkey` in their .git/config
or just doesn't have any secret keys on their keyring and they ask
for a signed tag with `git tag -s` we better make sure the resulting
tag was actually signed by gpg.

Prior versions of builtin git-tag allowed this failure to slip
by without error as they were not checking the return value of
the finish_command() so they did not notice when gpg exited with
an error exit status.  They also did not fail if gpg produced an
empty output or if read_in_full received an error from the read
system call while trying to read the pipe back from gpg.

Finally, we did not actually honor any return value from the do_sign
function as it returns ssize_t but was being stored into an unsigned
long.  This caused the compiler to optimize out the die condition,
allowing git-tag to continue along and create the tag object.

However, when gpg gets a wrong username, it exits before any read was done
and then the writing process receives SIGPIPE and program is terminated.
By ignoring this signal, anyway, the function write_or_die gets EPIPE from
write_in_full and exits returning 0 to the system without a message.
Here we better call to write_in_full directly so we can fail
printing a message and return safely to the caller.

With these issues fixed `git-tag -s` will now fail to create the
tag and will report a non-zero exit status to its caller, thereby
allowing automated helper scripts to detect (and recover from)
failure if gpg is not working properly.

8938410189 git-gui: Trim trailing slashes from untracked submodule names
Oddly enough `git ls-files --others` supplies us the name of an
untracked submodule by including the trailing slash but that
same git version will not accept the name with a trailing slash
through `git update-index --stdin`.  Stripping off that final
slash character before loading it into our file lists allows
git-gui to stage changes to submodules just like any other file.

This change should give git-gui users some basic submodule support,
but it is strictly at the plumbing level as we do not actually know
about calling the git-submodule porcelain that is a recent addition
to git 1.5.3.

3b9dfde3d6 git-gui: Assume untracked directories are Git submodules
If `git ls-files --others` returned us the name of a directory then
it is because Git has decided that this directory itself contains a
valid Git repository and its files shouldn't be listed as untracked
for this repository.

In such a case we should label the object as a Git repository and
not just as a directory.
