The option "-p" (or long "--preserve-merges") makes it possible to
rebase side branches including merges, without straightening the
history.
Example:
X
\
A---M---B
/
---o---O---P---Q
When the current HEAD is "B", "git rebase -i -p --onto Q O" will yield
X
\
---o---O---P---Q---A'---M'---B'
Note that this will
- _not_ touch X [*1*], it does
- _not_ work without the --interactive flag [*2*], it does
- _not_ guess the type of the merge, but blindly uses recursive or
whatever strategy you provided with "-s <strategy>" for all merges it
has to redo, and it does
- _not_ make use of the original merge commit via git-rerere.
*1*: only commits which reach a merge base between <upstream> and HEAD
are reapplied. The others are kept as-are.
*2*: git-rebase without --interactive is inherently patch based (at
least at the moment), and therefore merges cannot be preserved.

A pack-file can get created without any objects in it (to transfer "no

And while we probably should never create an index for such a pack, if we

Since git reset now gets chatty while resetting, we were getting errors
reported when a reset was done using the "reset branch to here" menu
item. With this we now read the progress messages from git reset and
update a progress bar. Because git reset outputs the progress messages
to standard error, and Tcl treats messages to standard error as error
messages, we have to invoke git reset via a shell and redirect standard
error into standard output.
This also fixes a bug in computing descendent heads when head ids
are changed via a reset.

Don't you just hate the fact sometimes, that git-rebase just applies
the patches, without any possibility to edit them, or rearrange them?
With "--interactive", git-rebase now lets you edit the list of patches,
so that you can reorder, edit and delete patches.
Such a list will typically look like this:
pick deadbee The oneline of this commit
pick fa1afe1 The oneline of the next commit
...
By replacing the command "pick" with the command "edit", you can amend
that patch and/or its commit message, and by replacing it with "squash"
you can tell rebase to fold that patch into the patch before that.
It is derived from the script sent to the list in

We always quote "unusual" byte values in a pathname using
C-string style, to make it safer for parsing scripts that do not
handle NUL separated records well (or just too lazy to bother).
The absolute minimum bytes that need to be quoted for this
purpose are TAB, LF (and other control characters), double quote
and backslash.
However, we have also always quoted the bytes in high 8-bit
range; this was partly because we were lazy and partly because
we were being cautious.
This introduces an internal "quote_path_fully" variable, and
core.quotepath configuration variable to control it. When set
to false, it does not quote bytes in high 8-bit range anymore
but passes them intact.
The variable defaults to "true" to retain the traditional
behaviour for now.

When the original $from address fails to yield a valid-looking
e-mail address, we created a bogus looking message ID, formatted
like this:
Message-Id: <11823357623688-git-send-email->
This commit fixes it by moving call to make_message_id() to
where it matters, namely, before the $message_id is needed to be
placed in the generated e-mail header; this has an important
side effect of making it clear that $from is already available.
Also throw in Sys::Hostname::hostname() just for fun, although I
suspect that the code would never trigger due to the modified
call sequence that makes sure $from is always available. This
is based on a suggestion by Michael Hendricks.

...
The main thing here is better parsing of the diff --git lines in the
output of git diff-tree -p. We now cope with filenames in quotes with
special chars escaped. If the filenames contain spaces they aren't
quoted, however, which can create difficulties in parsing. We get
around the difficulties by detecting the case when the filename hasn't
changed (chop the part after "diff --git " in two and see if the halves
match apart from a/ in one and b/ in the other), and if it hasn't
changed, we just use one half. If the filename has changed we wait
for the "rename from" and "rename to" lines, which give the old and
new filenames unambiguously.
This also improves the parsing of the output of git diff-tree.
Instead of using lindex to extract the filename, we take the part from
the first tab on, and if it starts with a quote, we use [lindex $str 0]
to remove the quotes and convert the escapes.
This also gets rid of some unused tagging of the diff text, uses
[string compare] instead of [regexp] in some places, and fixes the
regexp for detecting the @@ hunk-separator lines (the regexp wasn't
accepting a single number, as in "-0,0 +1" for example).

We were doing two execs for each tag - one to map the tag ID to a
commit ID and one to read the contents of the tag for later display.
This speeds up the process by not reading the contents of the tag
(instead it is read later if needed), and by using the -d flag to
git show-ref, which gives us refs/tags/foo^{} lines which give us
the commit ID. Also this uses string operations instead of regexps.

If there are local changes in the repository, i.e., git-diff-index HEAD
produces some output, then this optionally displays an extra row in
the graph as a child of the HEAD commit (but with a red circle to
indicate that it's not a real commit). There is a checkbox in the
preferences window to control whether gitk does this or not.
Clicking on the extra row shows the diffs between the working directory
and the HEAD (using git diff-index -p). The right-click menu on the
extra row allows the user to generate a patch containing the local diffs,
or to display the diffs between the working directory and any commit.

This only draws as much of the graph lines as is visible. This can
happen by adding coordinates on to an existing graph line or by
creating a new line. This means that we only need to have laid out
and optimized as much of the graph as is actually visible in order to
draw it, including the lines (previously we didn't draw a graph
line until we had laid out and optimized to the end of a segment of
the line, i.e. down to a down-arrow or to the row where the line's
commit is displayed). This also lets us get rid of the linesegends
list, and gives us an easy workaround for the X server bug that

This allows us to do compute-intensive processing, such as laying out
the graph, relatively efficiently while also having the GUI be
reasonably responsive. The problem previously was that file events
were serviced before X events, so reading from another process which
supplies data quickly (hi git rev-list :) could mean that X events
didn't get processed for a long time.

With some large repositories, a commit can end up on thousands of

This fixes it by just showing "many (N)" after "Branches:", "Follows:"
or "Precedes:", where N is the number of heads or tags. The limit

Instead of working out descendent heads and descendent & ancestor
branches in a two-pass algorithm, this reads and stores a simplified
version of the graph topology, and works out descendent/ancestor
tags and descendent heads on demand (with a bit of caching).
The advantages of this are, first, that we now don't have to use
--topo-order on the git rev-list process. Secondly, we don't have
to re-read the whole graph when tags or heads change or even when
the graph changes. Since we can cope with parents coming before
children, we can update the graph by running a git rev-list with
arguments that just give us the new commits, and merge the new
commits into the simplified graph.
The graph is simplified in the sense that commits with exactly one
parent and one child (which is >90% of them in most cases) are grouped
together into arcs joining nodes or 'branch/merge points', which are
the commits that don't have exactly 1 parent and 1 child. This reduces
the size of the graph substantially and decreases the time to traverse
it correspondingly.

This fixes "git log --follow" to hopefully not leak memory any more, and
also cleans it up a bit to look more like some of the other functions that
use "diff_queued_diff" (by *not* using it directly as a global in the
code, but by instead just taking a pointer to the diff queue and using
that).
As to "diff_queued_diff", I think it would be better off not as a global
at all, but as being just an entry in the "struct diff_options" structure,
but that's a separate issue, and there may be some subtle reason for why
it's currently a global.
Anyway, no real changes. Instead of having a magical first entry in the
diff-queue, we now end up just keeping the diff-queue clean, and keeping
our "preferred" file pairing in an internal "choice" variable. That makes
it easy to switch the choice around when we find a better one.

Ok, I've really held off doing this too damn long, because I'm lazy, and I
was always hoping that somebody else would do it.
But no, people keep asking for it, but nobody actually did anything, so I
decided I might as well bite the bullet, and instead of telling people
they could add a "--follow" flag to "git log" to do what they want to do,
I decided that it looks like I just have to do it for them..
The code wasn't actually that complicated, in that the diffstat for this
patch literally says "70 insertions(+), 1 deletions(-)", but I will have
to admit that in order to get to this fairly simple patch, you did have to
know and understand the internal git diff generation machinery pretty
well, and had to really be able to follow how commit generation interacts
with generating patches and generating the log.
So I suspect that while I was right that it wasn't that hard, I might have
been expecting too much of random people - this patch does seem to be
firmly in the core "Linus or Junio" territory.
To make a long story short: I'm sorry for it taking so long until I just
did it.
I'm not going to guarantee that this works for everybody, but you really
can just look at the patch, and after the appropriate appreciative noises
("Ooh, aah") over how clever I am, you can then just notice that the code
itself isn't really that complicated.
All the real new code is in the new "try_to_follow_renames()" function. It
really isn't rocket science: we notice that the pathname we were looking
at went away, so we start a full tree diff and try to see if we can
instead make that pathname be a rename or a copy from some other previous
pathname. And if we can, we just continue, except we show *that*
particular diff, and ever after we use the _previous_ pathname.
One thing to look out for: the "rename detection" is considered to be a
singular event in the _linear_ "git log" output! That's what people want
to do, but I just wanted to point out that this patch is *not* carrying
around a "commit,pathname" kind of pair and it's *not* going to be able to
notice the file coming from multiple *different* files in earlier history.
IOW, if you use "git log --follow", then you get the stupid CVS/SVN kind
of "files have single identities" kind of semantics, and git log will just
pick the identity based on the normal move/copy heuristics _as_if_ the
history could be linearized.
Put another way: I think the model is broken, but given the broken model,
I think this patch does just about as well as you can do. If you have
merges with the same "file" having different filenames over the two
branches, git will just end up picking _one_ of the pathnames at the point
where the newer one goes away. It never looks at multiple pathnames in
parallel.
And if you understood all that, you probably didn't need it explained, and
if you didn't understand the above blathering, it doesn't really mtter to
you. What matters to you is that you can now do
git log -p --follow builtin-rev-list.c
and it will find the point where the old "rev-list.c" got renamed to
"builtin-rev-list.c" and show it as such.
