git-add --interactive
A script to be driven when the user says "git add --interactive"
is introduced.
When it is run, first it runs its internal 'status' command to
show the current status, and then goes into its internactive
command loop.
The command loop shows the list of subcommands available, and
gives a prompt "What now> ". In general, when the prompt ends
with a single '>', you can pick only one of the choices given
and type return, like this:
*** Commands ***
1: status 2: update 3: revert 4: add untracked
5: patch 6: diff 7: quit 8: help
What now> 1
You also could say "s" or "sta" or "status" above as long as the
choice is unique.
The main command loop has 6 subcommands (plus help and quit).
* 'status' shows the change between HEAD and index (i.e. what
will be committed if you say "git commit"), and between index
and working tree files (i.e. what you could stage further
before "git commit" using "git-add") for each path. A sample
output looks like this:
staged unstaged path
1: binary nothing foo.png
2: +403/-35 +1/-1 git-add--interactive.perl
It shows that foo.png has differences from HEAD (but that is
binary so line count cannot be shown) and there is no
difference between indexed copy and the working tree
version (if the working tree version were also different,
'binary' would have been shown in place of 'nothing'). The
other file, git-add--interactive.perl, has 403 lines added
and 35 lines deleted if you commit what is in the index, but
working tree file has further modifications (one addition and
one deletion).
* 'update' shows the status information and gives prompt
"Update>>". When the prompt ends with double '>>', you can
make more than one selection, concatenated with whitespace or
comma. Also you can say ranges. E.g. "2-5 7,9" to choose
2,3,4,5,7,9 from the list. You can say '*' to choose
everything.
What you chose are then highlighted with '*', like this:
staged unstaged path
1: binary nothing foo.png
* 2: +403/-35 +1/-1 git-add--interactive.perl
To remove selection, prefix the input with - like this:
Update>> -2
After making the selection, answer with an empty line to
stage the contents of working tree files for selected paths
in the index.
* 'revert' has a very similar UI to 'update', and the staged
information for selected paths are reverted to that of the
HEAD version. Reverting new paths makes them untracked.
* 'add untracked' has a very similar UI to 'update' and
'revert', and lets you add untracked paths to the index.
* 'patch' lets you choose one path out of 'status' like
selection. After choosing the path, it presents diff between
the index and the working tree file and asks you if you want
to stage the change of each hunk. You can say:
y - add the change from that hunk to index
n - do not add the change from that hunk to index
a - add the change from that hunk and all the rest to index
d - do not the change from that hunk nor any of the rest to index
j - do not decide on this hunk now, and view the next
undecided hunk
J - do not decide on this hunk now, and view the next hunk
k - do not decide on this hunk now, and view the previous
undecided hunk
K - do not decide on this hunk now, and view the previous hunk
After deciding the fate for all hunks, if there is any hunk
that was chosen, the index is updated with the selected hunks.
* 'diff' lets you review what will be committed (i.e. between
HEAD and index).
This is still rough, but does everything except a few things I
think are needed.
* 'patch' should be able to allow splitting a hunk into
multiple hunks.
* 'patch' does not adjust the line offsets @@ -k,l +m,n @@
in the hunk header. This does not have major problem in
practice, but it _should_ do the adjustment.
* It does not have any explicit support for a merge in
progress; it may not work at all.

git-add: introduce --edit (to edit the diff vs. the index)
With "git add -e [<files>]", Git will fire up an editor with the current
diff relative to the index (i.e. what you would get with "git diff
[<files>]").
Now you can edit the patch as much as you like, including adding/removing
lines, editing the text, whatever. Make sure, though, that the first
character of the hunk lines is still a space, a plus or a minus.
After you closed the editor, Git will adjust the line counts of the hunks
if necessary, thanks to the --recount option of apply, and commit the
patch. Except if you deleted everything, in which case nothing happens
(for obvious reasons).

Remove diff machinery dependency from read-cache
Exal Sibeaz pointed out that some git files are way too big, and that
add_files_to_cache() brings in all the diff machinery to any git binary
that needs the basic git SHA1 object operations from read-cache.c. Which
is pretty much all of them.
It's doubly silly, since add_files_to_cache() is only used by builtin
programs (add, checkout and commit), so it's fairly easily fixed by just
moving the thing to builtin-add.c, and avoiding the dependency entirely.
I initially argued to Exal that it would probably be best to try to depend
on smart compilers and linkers, but after spending some time trying to
make -ffunction-sections work and giving up, I think Exal was right, and
the fix is to just do some trivial cleanups like this.
This trivial cleanup results in pretty stunning file size differences.
The diff machinery really is mostly used by just the builtin programs, and
you have things like these trivial before-and-after numbers:
-rwxr-xr-x 1 torvalds torvalds 1727420 2010-01-21 10:53 git-hash-object
-rwxrwxr-x 1 torvalds torvalds 940265 2010-01-21 11:16 git-hash-object
Now, I'm not saying that 940kB is good either, but that's mostly all the
debug information - you can see the real code with 'size':
text data bss dec hex filename
418675 3920 127408 550003 86473 git-hash-object (before)
230650 2288 111728 344666 5425a git-hash-object (after)
ie we have a nice 24% size reduction from this trivial cleanup.
It's not just that one file either. I get:
[torvalds@nehalem git]$ du -s /home/torvalds/libexec/git-core
45640 /home/torvalds/libexec/git-core (before)
33508 /home/torvalds/libexec/git-core (after)
so we're talking 12MB of diskspace here.
(Of course, stripping all the binaries brings the 33MB down to 9MB, so the
whole debug information thing is still the bulk of it all, but that's a
separate issue entirely)
Now, I'm sure there are other things we should do, and changing our
compiler flags from -O2 to -Os would bring the text size down by an
additional almost 20%, but this thing Exal pointed out seems to be some
good low-hanging fruit.

-rwxrwxr-x 1 torvalds torvalds 940265 2010-01-21 11:16 git-hash-object
Now, I'm not saying that 940kB is good either, but that's mostly all the
debug information - you can see the real code with 'size':
text data bss dec hex filename
418675 3920 127408 550003 86473 git-hash-object (before)
230650 2288 111728 344666 5425a git-hash-object (after)
ie we have a nice 24% size reduction from this trivial cleanup.
It's not just that one file either. I get:
[torvalds@nehalem git]$ du -s /home/torvalds/libexec/git-core
45640 /home/torvalds/libexec/git-core (before)
33508 /home/torvalds/libexec/git-core (after)
so we're talking 12MB of diskspace here.
(Of course, stripping all the binaries brings the 33MB down to 9MB, so the
whole debug information thing is still the bulk of it all, but that's a
separate issue entirely)
Now, I'm sure there are other things we should do, and changing our
compiler flags from -O2 to -Os would bring the text size down by an
additional almost 20%, but this thing Exal pointed out seems to be some
good low-hanging fruit.

Remove diff machinery dependency from read-cache
Exal Sibeaz pointed out that some git files are way too big, and that
add_files_to_cache() brings in all the diff machinery to any git binary
that needs the basic git SHA1 object operations from read-cache.c. Which
is pretty much all of them.
It's doubly silly, since add_files_to_cache() is only used by builtin
programs (add, checkout and commit), so it's fairly easily fixed by just
moving the thing to builtin-add.c, and avoiding the dependency entirely.
I initially argued to Exal that it would probably be best to try to depend
on smart compilers and linkers, but after spending some time trying to
make -ffunction-sections work and giving up, I think Exal was right, and
the fix is to just do some trivial cleanups like this.
This trivial cleanup results in pretty stunning file size differences.
The diff machinery really is mostly used by just the builtin programs, and
you have things like these trivial before-and-after numbers:

builtin-add.c: optimize -A option and "git add ."
The earlier "git add -A" change was done in a quite inefficient
way (i.e. it is as unefficient as "git add -u && git add ." modulo
one fork/exec and read/write index).
When the user asks "git add .", we do not have to examine all paths
we encounter and perform the excluded() and dir_add_name()
processing, both of which are slower code and use slower data structure
by git standards, especially when the index is already populated.
Instead, we implement "git add $pathspec..." as:
- read the index;
- read_directory() to process untracked, unignored files the current
way, that is, recursively doing readdir(), filtering them by pathspec
and excluded(), queueing them via dir_add_name() and finally do
add_files(); and
- iterate over the index, filtering them by pathspec, and update only
the modified/type changed paths but not deleted ones.
And "git add -A" becomes exactly the same as above, modulo:
- missing $pathspec means "." instead of being an error; and
- "iterate over the index" part handles deleted ones as well,
i.e. exactly what the current update_callback() in builtin-add.c does.
In either case, because fill_directory() does not use read_directory() to
read everything in, we need to add an extra logic to iterate over the
index to catch mistyped pathspec.

git-add: introduce --edit (to edit the diff vs. the index)
With "git add -e [<files>]", Git will fire up an editor with the current
diff relative to the index (i.e. what you would get with "git diff
[<files>]").
Now you can edit the patch as much as you like, including adding/removing
lines, editing the text, whatever. Make sure, though, that the first
character of the hunk lines is still a space, a plus or a minus.
After you closed the editor, Git will adjust the line counts of the hunks
if necessary, thanks to the --recount option of apply, and commit the
patch. Except if you deleted everything, in which case nothing happens
(for obvious reasons).

git-add --interactive
A script to be driven when the user says "git add --interactive"
is introduced.
When it is run, first it runs its internal 'status' command to
show the current status, and then goes into its internactive
command loop.
The command loop shows the list of subcommands available, and
gives a prompt "What now> ". In general, when the prompt ends
with a single '>', you can pick only one of the choices given
and type return, like this:
*** Commands ***
1: status 2: update 3: revert 4: add untracked
5: patch 6: diff 7: quit 8: help
What now> 1
You also could say "s" or "sta" or "status" above as long as the
choice is unique.
The main command loop has 6 subcommands (plus help and quit).
* 'status' shows the change between HEAD and index (i.e. what
will be committed if you say "git commit"), and between index
and working tree files (i.e. what you could stage further
before "git commit" using "git-add") for each path. A sample
output looks like this:
staged unstaged path
1: binary nothing foo.png
2: +403/-35 +1/-1 git-add--interactive.perl
It shows that foo.png has differences from HEAD (but that is
binary so line count cannot be shown) and there is no
difference between indexed copy and the working tree
version (if the working tree version were also different,
'binary' would have been shown in place of 'nothing'). The
other file, git-add--interactive.perl, has 403 lines added
and 35 lines deleted if you commit what is in the index, but
working tree file has further modifications (one addition and
one deletion).
* 'update' shows the status information and gives prompt
"Update>>". When the prompt ends with double '>>', you can
make more than one selection, concatenated with whitespace or
comma. Also you can say ranges. E.g. "2-5 7,9" to choose
2,3,4,5,7,9 from the list. You can say '*' to choose
everything.
What you chose are then highlighted with '*', like this:
staged unstaged path
1: binary nothing foo.png
* 2: +403/-35 +1/-1 git-add--interactive.perl
To remove selection, prefix the input with - like this:
Update>> -2
After making the selection, answer with an empty line to
stage the contents of working tree files for selected paths
in the index.
* 'revert' has a very similar UI to 'update', and the staged
information for selected paths are reverted to that of the
HEAD version. Reverting new paths makes them untracked.
* 'add untracked' has a very similar UI to 'update' and
'revert', and lets you add untracked paths to the index.
* 'patch' lets you choose one path out of 'status' like
selection. After choosing the path, it presents diff between
the index and the working tree file and asks you if you want
to stage the change of each hunk. You can say:
y - add the change from that hunk to index
n - do not add the change from that hunk to index
a - add the change from that hunk and all the rest to index
d - do not the change from that hunk nor any of the rest to index
j - do not decide on this hunk now, and view the next
undecided hunk
J - do not decide on this hunk now, and view the next hunk
k - do not decide on this hunk now, and view the previous
undecided hunk
K - do not decide on this hunk now, and view the previous hunk
After deciding the fate for all hunks, if there is any hunk
that was chosen, the index is updated with the selected hunks.
* 'diff' lets you review what will be committed (i.e. between
HEAD and index).
This is still rough, but does everything except a few things I
think are needed.
* 'patch' should be able to allow splitting a hunk into
multiple hunks.
* 'patch' does not adjust the line offsets @@ -k,l +m,n @@
in the hunk header. This does not have major problem in
practice, but it _should_ do the adjustment.
* It does not have any explicit support for a merge in
progress; it may not work at all.

git-add: introduce --edit (to edit the diff vs. the index)
With "git add -e [<files>]", Git will fire up an editor with the current
diff relative to the index (i.e. what you would get with "git diff
[<files>]").
Now you can edit the patch as much as you like, including adding/removing
lines, editing the text, whatever. Make sure, though, that the first
character of the hunk lines is still a space, a plus or a minus.
After you closed the editor, Git will adjust the line counts of the hunks
if necessary, thanks to the --recount option of apply, and commit the
patch. Except if you deleted everything, in which case nothing happens
(for obvious reasons).

git-add --all: add all files
People sometimes find that "git add -u && git add ." are 13 keystrokes too
many. This reduces it by nine.
The support of this has been very low priority for me personally, because
I almost never do "git add ." in a directory with already tracked files,
and in a new directory, there is no point saying "git add -u".
However, for two types of people (that are very different from me), this
mode of operation may make sense and there is no reason to leave it
unsupported. That is:
(1) If you are extremely well disciplined and keep perfect .gitignore, it
always is safe to say "git add ."; or
(2) If you are extremely undisciplined and do not even know what files
you created, and you do not very much care what goes in your history,
it does not matter if "git add ." included everything.
So there it is, although I suspect I will not use it myself, ever.
It will be too much of a change that is against the expectation of the
existing users to allow "git commit -a" to include untracked files, and
it would be inconsistent if we named this new option "-a", so the short
option is "-A". We _might_ want to later add "git commit -A" but that is
a separate topic.

builtin-add.c: optimize -A option and "git add ."
The earlier "git add -A" change was done in a quite inefficient
way (i.e. it is as unefficient as "git add -u && git add ." modulo
one fork/exec and read/write index).
When the user asks "git add .", we do not have to examine all paths
we encounter and perform the excluded() and dir_add_name()
processing, both of which are slower code and use slower data structure
by git standards, especially when the index is already populated.
Instead, we implement "git add $pathspec..." as:
- read the index;
- read_directory() to process untracked, unignored files the current
way, that is, recursively doing readdir(), filtering them by pathspec
and excluded(), queueing them via dir_add_name() and finally do
add_files(); and
- iterate over the index, filtering them by pathspec, and update only
the modified/type changed paths but not deleted ones.
And "git add -A" becomes exactly the same as above, modulo:
- missing $pathspec means "." instead of being an error; and
- "iterate over the index" part handles deleted ones as well,
i.e. exactly what the current update_callback() in builtin-add.c does.
In either case, because fill_directory() does not use read_directory() to
read everything in, we need to add an extra logic to iterate over the
index to catch mistyped pathspec.

_GIT_INDEX_OUTPUT: allow plumbing to output to an alternative index file.
When defined, this allows plumbing commands that update the
index (add, apply, checkout-index, merge-recursive, mv,
read-tree, rm, update-index, and write-tree) to write their
resulting index to an alternative index file while holding a
lock to the original index file. With this, git-commit that
jumps the index does not have to make an extra copy of the index
file, and more importantly, it can do the update while holding
the lock on the index.
However, I think the interface to let an environment variable
specify the output is a mistake, as shown in the documentation.
If a curious user has the environment variable set to something
other than the file GIT_INDEX_FILE points at, almost everything
will break. This should instead be a command line parameter to
tell these plumbing commands to write the result in the named
file, to prevent stupid mistakes.

we encounter and perform the excluded() and dir_add_name()
processing, both of which are slower code and use slower data structure
by git standards, especially when the index is already populated.
Instead, we implement "git add $pathspec..." as:
- read the index;
- read_directory() to process untracked, unignored files the current
way, that is, recursively doing readdir(), filtering them by pathspec
and excluded(), queueing them via dir_add_name() and finally do
add_files(); and
- iterate over the index, filtering them by pathspec, and update only
the modified/type changed paths but not deleted ones.
And "git add -A" becomes exactly the same as above, modulo:
- missing $pathspec means "." instead of being an error; and
- "iterate over the index" part handles deleted ones as well,
i.e. exactly what the current update_callback() in builtin-add.c does.
In either case, because fill_directory() does not use read_directory() to
read everything in, we need to add an extra logic to iterate over the
index to catch mistyped pathspec.
