Don't fflush(stdout) when it's not helpful
This patch arose from a discussion started by Jim Meyering's patch
whose intention was to provide better diagnostics for failed writes.
Linus proposed a better way to do things, which also had the added
benefit that adding a fflush() to git-log-* operations and incremental
git-blame operations could improve interactive respose time feel, at
the cost of making things a bit slower when we aren't piping the
output to a downstream program.
This patch skips the fflush() calls when stdout is a regular file, or
if the environment variable GIT_FLUSH is set to "0". This latter can
speed up a command such as:
GIT_FLUSH=0 strace -c -f -e write time git-rev-list HEAD | wc -l
a tiny amount.

git: Try a bit harder not to lose errno in stdio
This switches the checks around upon the exit codepath of the
git wrapper, so that we may recover at least non-transient errors.
It's still not perfect. As I've been harping on, stdio simply isn't very
good for error reporting. For example, if an IO error happened, you'd want
to see EIO, wouldn't you? And yes, that's what the kernel would return.
However, with buffered stdio (and flushing outside of our control), what
would likely happen is that some intermediate error return _does_ return
EIO, but then the kernel might decide to re-mount the filesystem read-only
due to the error, and the actual *report* for us might be
"write failure on standard output: read-only filesystem"
which lost the EIO.

Correct usages of sed in git-tag for Mac OS X
Both `git-tag -l` and `git tag -v` fail on Mac OS X due to their

We now stick to only standard sed, which does make our sed scripts

gitk: Improve handling of whitespace and special chars in filenames
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).

gitk: Cope with commit messages with carriage-returns and initial blank lines
In some repositories imported from other systems we can get carriage
return characters in the commit message, which leads to a multi-line
headline being displayed in the summary window, which looks bad.
Also some commit messages start with one or more blank lines, which
leads to an empty headline. This fixes these problems.

gitk: Implement a simple scheduler for the compute-intensive stuff
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 this, gitk finishes laying out the graph slightly sooner and
still responds to the GUI while doing so.

gitk: Don't try to list large numbers of tags or heads in the details pane
With some large repositories, a commit can end up on thousands of
branches, which results in an extremely long "Branches:" line in the

to scroll.
This fixes it by just showing "many (N)" after "Branches:", "Follows:"
or "Precedes:", where N is the number of heads or tags. The limit
is currently set at 20 but could be made configurable (and the "many"
could be a link to pop up a window listing them all in case anyone
really wants to know).

gitk: New infrastructure for working out branches & previous/next tags
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.

Fix up "git log --follow" a bit..
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.

Finally implement "git log --follow"
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.

Avoid src:dst syntax as default bash completion for git push
Raimund Bauer just discovered that the default bash completion for
a local branch name in a git-push line is not the best choice when
the branch does not exist on the remote system.
In the past we have always completed the local name 'test' as
"test:test", indicating that the destination name is the same as
the local name. But this fails when "test" does not yet exist on
the remote system, as there is no "test" branch for it to match
the name against.
Fortunately git-push does the right thing when given just the
local branch, as it assumes you want to use the same name in the
destination repository. So we now offer "test" as the completion
in a git-push line, and let git-push assume that is also the remote
branch name.
We also still support the remote branch completion after the :,
but only if the user manually adds the colon before trying to get
a completion.

git-gui: Don't require $DISPLAY just to get --version
Junio asked that we don't force the user to have a valid X11 server

This makes sense, the user may be an automated tool that is running
without an X server available to it, such as a build script or other
sort of package management system. Or it might just be a user working
in a non-GUI environment and wondering "what version of git-gui do I
have installed?".
Tcl has a lot of warts, but one of its better ones is that a comment
can be continued to the next line by escaping the LF that would have
ended the comment using a backslash-LF sequence. In the past we have
used this trick to escape away the 'exec wish' that is actually a Bourne
shell script and keep Tcl from executing it.
I'm using that feature here to comment out the Bourne shell script and
hide it from the Tcl engine. Except now our Bourne shell script is a
few lines long and checks to see if it should print the version, or not.

These rules are a little bit on the messy side, as each of our

We now can also set QUIET= (nothing) to see the rules that are used

So git-gui guesses that its library should be found within the

In my first version of this patch I tried to use `cygpath` to resolve
/usr/bin and /usr/share to test that they were in the same relative
locations, but that didn't work out correctly as we were actually
testing /usr/share against itself, so it always was equal, and we
always used relative paths. So my original solution was quite wrong.
