CDPATH has two problems:
* It takes scripts to unexpected places (somebody had
CDPATH=..:../..:$HOME and the "cd" in git-clone.sh:get_repo_base
took him to $HOME/.git when he said "clone foo bar" to clone a
repository in "foo" which had "foo/.git"). CDPATH mechanism does
not implicitly give "." at the beginning of CDPATH, which is
the most irritating part.
* The extra echo when it does its thing confuses scripts further.
Most of our scripts that use "cd" includes git-sh-setup so the problem
is primarily fixed there. git-clone starts without a repository, and
it needs its own fix.

If you make a commit on a path, and then make the path
cache-dirty afterwards without changing its contents, 'git
checkout' to switch to another branch is prevented because
switching the branches done with 'read-tree -m -u $current
$next' detects that the path is cache-dirty, but it does not
bother noticing that the contents of the path has not been
actualy changed.
Since switching branches would involve checking out paths
different in the two branches, hence it is reasonably expensive
operation, we can afford to run update-index before running
read-tree to reduce this kind of false change from triggering
the check needlessly.

There are several undocumented dependencies in the .spec and in the
INSTALL files. The following is from Fedora, perhaps other RPM
distributions call the packages differently.
Also, the manpages aren't always installed gzipped.
Updates to git-core.spec.in file:
- Some git scripts use Perl
- gitk needs wish, which is part of TCL/Tk.
- curl is used all over
- Need the ssh program from openssh-clients
Updates to INSTALL:
- Mention wish
- Mention ssh

This allows any arbitrary flags to "grep", and knows about the few
special grep flags that take an argument too.
It also allows some flags for git-ls-files, although their usefulness
is questionable.
With this, something line
git grep -w -1 pattern
works, without the script enumerating every possible flag.
[jc: this is the version Linus sent out after I showed him a
barf-o-meter test version that avoids shell arrays. He must
have typed this version blindly, since he said:
I'm not barfing, but that's probably because my brain just shut
down and is desperately trying to gouge my eyes out with a spoon.
I slightly fixed it to catch the remaining arguments meant to be

Very convenient shorthand for
git-ls-files [file-patterns] | xargs grep <pattern>
which I tend to do all the time.
Yes, it's trivial, but it's really nice. I can do
git grep '\<some_variable\>' arch/i386 include/asm-i386
and it does exactly what you'd think it does. And since it just uses the
normal git-ls-files file patterns, you can do things like
git grep something 'include/*.h'
and it will search all header files under the include/ subdirectory.

This should work around the compilation problem Johannes Schindelin
and others had on Mac OS/X.
Quoting Linus:
Any operating system where socklen_t is anything else than "int" is
terminally broken. The people who introduced that typedef were confused,
and I actually had to argue with them that it was fundamentally wrong:
there is no other valid type than "int" that makes sense for it.

The new command 'git merge' takes the current head and one or more
remote heads, with the commit log message for the automated case.
If the heads being merged are simple fast-forwards, it acts the
same way as the current 'git resolve'. Otherwise, it tries
different merge strategies and takes the result from the one that
succeeded auto-merging, if there is any.
If no merge strategy succeeds auto-merging, their results are
evaluated for number of paths needed for hand resolving, and the
one with the least number of such paths is left in the working
tree. The user is asked to resolve them by hand and make a
commit manually.
The calling convention from the 'git merge' driver to merge
strategy programs is very simple:
- A strategy program is to be called 'git-merge-<strategy>'.
- They take input of this form:
<common1> <common2> ... '--' <head> <remote1> <remote2>...
That is, one or more the common ancestors, double dash, the
current head, and one or more remote heads being merged into
the current branch.
- Before a strategy program is called, the working tree is
matched to the current <head>.
- The strategy program exits with status code 0 when it
successfully auto-merges the given heads. It should do
update-cache for all the merged paths when it does so -- the
index file will be used to record the merge result as a
commit by the driver.
- The strategy program exits with status code 1 when it leaves
conflicts behind. It should do update-cache for all the
merged paths that it successfully auto-merged, and leave the
cache entry in the index file as the same as <head> for paths
it could not auto-merge, and leave its best-effort result
with conflict markers in the working tree when it does so.
- The strategy program exists with status code other than 0 or
1 if it does not handle the given merge at all.
As examples, this commit comes with merge strategies based on
'git resolve' and 'git octopus'.

The 'git bisect' command was very unforgiving in that once you made a

When (A,B) ==> (B,C) rename-copy was detected, we incorrectly said
that C was created by copying B. This is because we only check if the
path of rename/copy source still exists in the resulting tree to see
if the file is renamed out of existence. In this case, the new B is
created by copying or renaming A, so the original B is lost and we
should say C is a rename of B not a copy of B.

We now keep track of the patches merged in each branch since they have
diverged, using the records that the Arch "logs" provide. Merge parents
for a commit are defined if we are merging a series of patches that starts
from the mergebase.
If patches from a related branch are merged out-of-order, we keep track of
how much has been merged sequentially -- the tip of that sequential merge
is our new parent from that branch.
This mechanism works very well for branches that merge in dovetail and/or
flying fish patterns, probably less well for others.
