git-prune is not safe when run uncontrolled in parallel while
other git operations are creating new objects. To avoid
mistakes, do not run git-prune by default from git-gc.

We currently do not support fetching/cloning from a shallow repository
nor pushing into one. Make sure these are not attempted so that we
do not have to worry about corrupting repositories needlessly.

Earlier, git_connect() returned the same fd twice or two
separate fds, depending on the way the connection was made (when
we are talking to the other end over a single socket, we used
the same fd twice, and when our end is connected to a pipepair
we used two).
This forced callers who do close() and dup() to really care
which was which, and most of the existing callers got this
wrong, although without much visible ill effect. Many were
closing the same fd twice when we are talking over a single
socket, and one was leaking a fd.
This fixes it to uniformly use two separate fds, so if somebody
wants to close only reader side can just do close() on it
without worrying about it accidentally also closing the writer
side or vice versa.

This reverts commit 9b088c4e39.
Protecting 'mature' objects does not make it any safer. We should
admit that git-prune is inherently unsafe when run in parallel with
other operations without involving unwarranted locking overhead,
and with the latest git, even rebase and reset would not immediately
create crufts anyway.
Marco Candrian noticed that one cat-file example refers to a
blob object that is never used in the example sequence.
The bug is interesting in that the output from the botched
sample command is consistent with the incorrect blob object
name ;-).

This changes the output so the list at the top shows the reflog
message, along with their relative timestamps.
You can use --reflog=<n> to show <n> most recent log entries, or
use --reflog=<n>,<b> to show <n> entries going back from the
entry <b>. <b> can be either a number (so --reflog=4,20 shows 4
records starting from @{20}) or a timestamp (e.g. --reflog='4,1 day').
Here is a sample output (with --list option):
$ git show-branch --reflog=10 --list jc/show-reflog

At @{9}, I had a commit to complete 5 patch series, but I wanted
to consolidate two commits that enhances read_ref_at() into one
(they were @{9}^ and @{9}~3), and another two that touch show-branch
into one (@{9} and @{9}~2).
I first saved them with "format-patch -4", and then did a reset
at @{8}. At @{7}, I applied one of them with "am", and then
used "git-apply" on the other one, and amended the commit at
@{6} (so @{6} and @{7} has the same parent). I did not like the
log message, so I amended again at @{5}.
Then I cherry-picked @{9}~2 to create @{3} (the log message
shows that it needs to learn to set GIT_REFLOG_ACTION -- it uses
"git-commit" and the log entry is attributed for it). Another
cherry-pick built @{2} out of @{9}, but what I wanted to do was
to squash these two into one, so I did a "reset HEAD^" at @{1}
and then made the final commit by amending what was at the top.

You can pass an extra argument to the function to receive the
reflog message information. Also when the log does not go back
beyond the point the user asked, the cut-off time and count are
given back to the caller for emitting the error messages as
appropriately.
We could later add configuration for get_sha1_basic() to make it
an error instead of it being just a warning.

Way back when Junio developed the 64 bit index topic he came up
with a means of changing the .idx file format so that older Git
clients would recognize that they don't understand the file and
refuse to read it, while newer clients could tell the difference
between the old-style and new-style .idx files. Unfortunately
this wasn't recorded anywhere.
This change documents how we might go about changing the .idx
file format by using a special signature in the first four bytes.
Credit (and possible blame) goes completely to Junio for thinking
up this technique.
The change also modifies the error message of the current Git code
so that users get a recommendation to upgrade their Git software
should this version or later encounter a new-style .idx which it
cannot process. We already do this for the .pack files, but since
we usually process the .idx files first its important that these
files are recognized and encourage an upgrade.
