There is no reason to forbid a dirty work tree when reverting or
cherry-picking a change, as long as the index is clean.
The scripted version used to allow it:
case "$no_commit" in
t)
# We do not intend to commit immediately. We just want to
# merge the differences in.
head=$(git-write-tree) ||
die "Your index file is unmerged."
;;
*)
head=$(git-rev-parse --verify HEAD) ||
die "You do not have a valid HEAD"
files=$(git-diff-index --cached --name-only $head) || exit
if [ "$files" ]; then
die "Dirty index: cannot $me (dirty: $files)"
fi
;;
esac
but C rewrite tightened the check, probably by mistake.

Back in e3c6f240fd Junio taught
git-fetch to avoid copying objects when we are fetching from
a repository that is already registered as an alternate object
database. In such a case there is no reason to copy any objects
as we can already obtain them through the alternate.
However we need to ensure the objects are all reachable, so we
run `git rev-list --objects $theirs --not --all` to verify this.
If any object is missing or unreadable then we need to fetch/copy
the objects from the remote. When a missing object is detected
the git-rev-list process will exit with a non-zero exit status,
making this condition quite easy to detect.
Although git-fetch is currently a builtin (and so is rev-list)
we cannot invoke the traverse_objects() API at this point in the
transport code. The object walker within traverse_objects() calls
die() as soon as it finds an object it cannot read. If that happens
we want to resume the fetch process by calling do_fetch_pack().
To get around this we spawn git-rev-list into a background process
to prevent a die() from killing the foreground fetch process,
thus allowing the fetch process to resume into do_fetch_pack()
if copying is necessary.
We aren't interested in the output of rev-list (a list of SHA-1
object names that are reachable) or its errors (a "spurious" error
about an object not being found as we need to copy it) so we redirect
both stdout and stderr to /dev/null.
We run this git-rev-list based check before any fetch as we may
already have the necessary objects local from a prior fetch. If we
don't then its very likely the first $theirs object listed on the
command line won't exist locally and git-rev-list will die very
quickly, allowing us to start the network transfer. This test even
on remote URLs may save bandwidth if someone runs `git pull origin`,
sees a merge conflict, resets out, then redoes the same pull just
a short time later. If the remote hasn't changed between the two
pulls and the local repository hasn't had git-gc run in it then
there is probably no need to perform network transfer as all of
the objects are local.
Documentation for the new quickfetch function was suggested and
written by Junio, based on his original comment in git-fetch.sh.

Some uses of git-rev-list are to run it with --objects to see if
a range of objects between two or more commits is fully connected
or not. In such a case the caller doesn't care about the actual
object names or hash hints so formatting this data only for it to
be dumped to /dev/null by a redirect is a waste of CPU time. If
all the caller needs is the exit status then --quiet can be used
to bypass the commit and object formatting.

Some callers may wish to redirect stderr to /dev/null in some
contexts, such as if they are executing a command only to get

may produce as a side-effect of computing that exit status.

Previously git-fetch.sh used `git cat-file -t` to determine if an
object referenced by a tag exists, and if so fetch that tag locally.
This was subtly broken during the port to C based builtin-fetch as
lookup_object() only works to locate an object if it was previously
accessed by the transport. Not all transports will access all
objects in this way, so tags were not always being fetched.
The rsync transport never loads objects into the internal object
table so automated tag following didn't work if rsync was used.
Automated tag following also didn't work on the native transport
if the new tag was behind the common point(s) negotiated between
the two ends of the connection as the tag's referrant would not
be loaded into the internal object table. Further the automated
tag following was broken with the HTTP commit walker if the new
tag's referrant was behind an existing ref, as the walker would
stop before loading the tag's referrant into the object table.
Switching to has_sha1_file() restores the original behavior from
the shell script by checking if the object exists in the ODB,
without relying on the state left behind by a transport.

When you have a merge conflict and want to bypass the commit causing it,
you don't want to care about the dirty state of the working tree.
Also, don't git reset --hard HEAD in the rebase-skip test, so that the
lack of support for this is detected.

strchrnul() was introduced in glibc in April 1999 and included in

users would get to use the optimized version in glibc. Of the
remaining few some might get to use a slightly slower version
than necessary but probably not slower than what we have today.
Unfortunately, __GLIBC_PREREQ() macro was not available in glibc 2.1.1
which was short lived but already supported strchrnul(). Odd minority
users of that library needs to live with our compatibility inline version.

# create "deltifiable" objects in between big objects
for i in $(seq -w 2 2 64)

cp grow file_$i
git add file_$i
rm file_$i
done
rm grow
# create a pack with them

git repack -a -d

As Jeff King remarked, format strings with duplicate placeholders can
be slow to expand, because each instance is calculated anew.
This patch makes use of the fact that format_commit_message() and its
helper functions only ever add stuff to the end of the strbuf. For
certain expensive placeholders, store the offset and length of their
expansion with the strbuf at the first occurrence. Later they
expansion result can simply be copied from there -- no malloc() or
strdup() required.
These certain placeholders are the abbreviated commit, tree and
parent hashes, as the search for a unique abbreviated hash is quite
costly. Here are the times for next (best of three runs):
$ time git log --pretty=format:%h >/dev/null
real 0m0.611s
user 0m0.404s
sys 0m0.204s
$ time git log --pretty=format:%h%h%h%h >/dev/null
real 0m1.206s
user 0m0.744s
sys 0m0.452s
And here those with this patch (and the previous two); the speedup
of the single placeholder case is just noise:
$ time git log --pretty=format:%h >/dev/null
real 0m0.608s
user 0m0.416s
sys 0m0.192s
$ time git log --pretty=format:%h%h%h%h >/dev/null

As Jeff King pointed out, some placeholder expansions are related to
each other: the steps to calculate one go most of the way towards
calculating the other, too.
This patch makes format_commit_message() parse the commit message
only once, remembering the position of each item. This speeds up
handling of format strings containing multiple placeholders from the
set %s, %a*, %c*, %e, %b.
Here are the timings for the git version in next. The first one is
to estimate the overhead of the caching, the second one is taken
from http://svn.tue.mpg.de/tentakel/trunk/tentakel/Makefile as an
example of a format string found in the wild. The times are the
fastest of three consecutive runs in each case:
$ time git log --pretty=format:%e >/dev/null
real 0m0.381s
user 0m0.340s
sys 0m0.024s
$ time git log --pretty=format:"* %cd %cn%n%n%s%n%b" >/dev/null
real 0m0.623s
user 0m0.556s
sys 0m0.052s
And here the times with this patch:
$ time git log --pretty=format:%e >/dev/null
real 0m0.385s
user 0m0.332s
sys 0m0.040s
$ time git log --pretty=format:"* %cd %cn%n%n%s%n%b" >/dev/null
