Not having an open FD in the 0--2 range can lead to strange results,
for example, a subsequent open() may return 2 (stderr) and then a
die() would clobber this file.
git-daemon and git-shell already guarded against this, but apparently
users also manage to trip over it in other git commands. So we call
sanitize_stdfds() during main git startup.
Since these FDs are inherited, this covers all use of 'git foo ...',
and all internal C commands when called directly. It does not fix
shell/perl commands called directly.

Both daemon.c and shell.c contain logic to open FDs 0/1/2 from
/dev/null if they are not already open. Move the function in daemon.c
to setup.c and use it in shell.c, too.
While there, remove a 'not' that inverted the meaning of the comment.

Currently, when an invalid revision is specified, the error message is:
fatal: Needed a single revision
This is misleading because, you might think there is something wrong
with the command line as a whole.
Now the user gets a more meaningful error message, showing the invalid
revision.

Commit 682c7d2 (upload-pack: fix off-by-one depth calculation in shallow
clone) introduced a new check in get_shallow_commits to decide when to
stop traversing the history and mark the current commit as a shallow
root.
With this new check in place, the old check can no longer be true, since
the first check always fires first. This commit removes that check,
making the code a bit more simple again.

The email addresses in the records read from the .mailmap file are
downcased very early, and then used to match against e-mail
addresses in the input. Because we do use case insensitive version
of string list to manage these entries, there is no need to do this,
and worse yet, downcasing the rewritten/canonical e-mail read from
the .mailmap file loses information.
Stop doing that, and also make the string list used to keep multiple
names for an mailmap entry case insensitive (the code that uses the
list, lookup_prefix(), expects a case insensitive match).

In parse_name_and_email() function, there is this line:
*name = (nstart < nend ? nstart : NULL);
When the function is given a buffer "A <A@example.org> <old@x.z>",
nstart scans from the beginning of the buffer, skipping whitespaces
(there isn't any, so nstart points at the buffer), while nend starts
from one byte before the first '<' and skips whitespaces backwards
and stops at the first non-whitespace (i.e. it hits "A" at the
beginning of the buffer). nstart == nend in this case for a
single-letter name, and an off-by-one error makes it fail to pick up
the name, which makes the entry equivalent to
<A@example.org> <old@x.z>
without the name.

As plumbing accessible to scripts and other porcelain, check-mailmap
publishes the stable, well-tested .mailmap functionality employed by
built-in Git commands. Consequently, script authors need not
re-implement .mailmap functionality manually, thus avoiding potential

People change email addresses quite often and sometimes forget to
add their entry to the mailmap file. I have contacted lots of
people, whose name occurs multiple times in the short log having
different email addresses. The entries in the mailmap of this patch
are either confirmed by them or are trivial. Trivial means
different capitalisation of the domain (@MIT.EDU and @mit.edu) or
the domain was localhost, (none) or @local.
Additionally to adding (name, email) mappings to the .mailmap file,
it has also been sorted ("LC_ALL=C /usr/bin/sort", byte-value sort).
While the most changes happen at the email addresses, we also have a
name change in here. Karl Hasselström is now known as Karl Wiberg
due to marriage. Congratulations!
To find out whom to contact I used the following small
script:
#!/bin/bash
git shortlog -sne |awk '{ NF--; $1=""; print }' |sort |uniq -d > mailmapdoubles
while read line ; do
# remove leading whitespace
trimmed=$(echo $line | sed -e 's/^ *//g' -e 's/ *$//g')
echo "git shortlog -sne | grep \""$trimmed"\""
done < mailmapdoubles > mailmapdoubles2
sh mailmapdoubles2
rm mailmapdoubles
rm mailmapdoubles2
Also interesting for similar tasks are these snippets:
# Finding out duplicates by comparing email addresses:
git shortlog -sne |awk '{ print $NF }' |sort |uniq -d
# Finding out duplicates by comparing names:
git shortlog -sne |awk '{ NF--; $1=""; print }' |sort |uniq -d

The document says one cannot push from a shallow clone. But that is
not true (maybe it was at some point in the past). The client does not
stop such a push nor does it give any indication to the receiver that
this is a shallow push. If the receiver accepts it, it's in.
Since 52fed6e (receive-pack: check connectivity before concluding "git
push" - 2011-09-02), receive-pack is prepared to deal with broken
push, a shallow push can't cause any corruption. Update the document
to reflect that.
