The "contains" algorithm runs into an infinite loop if the needle string
has zero length. The loop could be modified to handle this, but it makes
more sense to simply have an empty needle return no matches. Thus, a
command like
git log -S
produces no output.
We place the check at the top of the function so that we get the same
results with or without --pickaxe-regex. Note that until now,
git log -S --pickaxe-regex
would match everything, not nothing.
Arguably, an empty pickaxe string should simply produce an error
message; however, this is still a useful assertion to add to the
algorithm at this layer of the code.
Noticed by Bill Lear.

The code that uses committer_info() in reflog can barf and die
whenever it is asked to update a ref. And I do not think
calling ignore_missing_committer_name() upfront like recent
receive-pack did in the aplication is a reasonable workaround.
What the patch does.
- git_committer_info() takes one parameter. It used to be "if
this is true, then die() if the name is not available due to
bad GECOS, otherwise issue a warning once but leave the name
empty". The reason was because we wanted to prevent bad
commits from being made by git-commit-tree (and its
callers). The value 0 is only used by "git var -l".
Now it takes -1, 0 or 1. When set to -1, it does not
complain but uses the pw->pw_name when name is not
available. Existing 0 and 1 values mean the same thing as
they used to mean before. 0 means issue warnings and leave
it empty, 1 means barf and die.
- ignore_missing_committer_name() and its existing caller
(receive-pack, to set the reflog) have been removed.
- git-format-patch, to come up with the phoney message ID when
asked to thread, now passes -1 to git_committer_info(). This
codepath uses only the e-mail part, ignoring the name. It
used to barf and die. The other call in the same program
when asked to add signed-off-by line based on committer
identity still passes 1 to make sure it barfs instead of
adding a bogus s-o-b line.
- log_ref_write in refs.c, to come up with the name to record
who initiated the ref update in the reflog, passes -1. It
used to barf and die.
The last change means that git-update-ref, git-branch, and
commit walker backends can now be used in a repository with
reflog by somebody who does not have the user identity required
to make a commit. They all used to barf and die.
I've run tests and all of them seem to pass, and also tried "git
clone" as a user whose GECOS is empty -- git clone works again
now (it was broken when reflog was enabled by default).
But this definitely needs extra sets of eyeballs.

Currently, the vc-git-checkout function uses `git checkout' to fetch a
file from the git repository to the working copy. However, it is
completely ignoring the input argument that specifies the destination
file. `git-checkout' does not support specifying this, so we have to
use `git-cat-file', capture the output in a buffer and then save it.

Do *NOT* try this on a repository you care about:
git pack-refs --all --prune
git pack-refs
because while the first "pack-refs" does the right thing, the second
pack-refs will totally screw you over.
This is because the second one tries to pack only tags; we should
also pack what are already packed -- otherwise we would lose them.

If a repository was checked out via git-cvsserver and then later a new
file is added to the git repository via some other method; a CVS update
wasn't fetching the new file.
It would be reported as a new file as
A some/dir/newfile.c
but would never appear in the directory.
The problem seems to be that git-cvsserver was treating these two cases
identically, as "A" type results.
1. New file in repository
2. New file locally
In fact, traditionally, case 1 is treated as a "U" result, and case 2
only is treated as an "A" result. "A", should just report that the file
is added locally and then skip that file during an update as there is
(of course) nothing to send.
In both these cases there is no working revision, so the checking for
"is there no working revision" will return true. The test for case 2
needs refining to say "if there is no working revision and no upstream
revision". This patch does just that, leaving case 1 to be handled by
the normal "U" handler.
I've also updated the log message to more accurately describe the
operation. i.e. that "A" means that content is scheduled for addition;
not that it actually has been added.

This makes git-fetch over git native protocol to automatically
decide to keep the downloaded pack if the fetch results in more
than 100 objects, just like receive-pack invoked by git-push
does. This logic is disabled when --keep is explicitly given
from the command line, so that a very small clone still keeps
the downloaded pack as before.
The 100 threshold can be adjusted with fetch.unpacklimit
configuration. We might want to introduce transfer.unpacklimit
to consolidate the two unpacklimit variables, which will be a
topic for the next patch.

This separates the connectivity check into separate codepaths,
one for reachable objects and the other for unreachable ones,
while adding a lot of comments to explain what is going on.
When checking an unreachable object, unlike a reachable one, we
do not have to complain if it does not exist (we used to
complain about a missing blob even when the only thing that
references it is a tree that is dangling). Also we do not have
to check and complain about objects that are referenced by an
unreachable object.
This makes the messages from fsck-objects a lot less noisy and

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 ;-).
