are included in the branch, and which aren't. Performing this
tracking can be tedious and error prone for the frontend to do,
especially if its foreign data source cannot supply the changed

fast-import now allows a frontend to request that a branch's tree
be wiped clean (reset to the empty tree) at the start of a commit,
allowing the frontend to feed in all paths which belong on the branch.
This is ideal for a tar-file importer frontend, for example, as
the frontend just needs to reformat the tar data stream into a gfi
data stream, which may be something a few Perl regexps can take

Support RFC 2822 date parsing in fast-import.
Since some frontends may be working with source material where
the dates are only readily available as RFC 2822 strings, it is
more friendly if fast-import exposes Git's parse_date() function
to handle the conversion. This way the frontend doesn't need
to perform the parsing itself.
The new --date-format option to fast-import can be used by a
frontend to select which format it will supply date strings in.
The default is the standard `raw` Git format, which fast-import
has always supported. Format rfc2822 can be used to activate the
parse_date() function instead.
Because fast-import could also be useful for creating new, current
commits, the format `now` is also supported to generate the current
system timestamp. The implementation of `now` is a trivial call
to datestamp(), but is actually a whole whopping 3 lines so that
fast-import can verify the frontend really meant `now`.
As part of this change I have added validation of the `raw` date
format. Prior to this change fast-import would accept anything
in a `committer` command, even if it was seriously malformed.
Now fast-import requires the '> ' near the end of the string and
verifies the timestamp is formatted properly.

Reduce memory usage of fast-import.
Some structs are allocated rather frequently, but were using integer
types which were far larger than required to actually store their
full value range.
As packfiles are limited to 4 GiB we don't need more than 32 bits to
store the offset of an object within that packfile, an `unsigned long`
on a 64 bit system is likely a 64 bit unsigned value. Saving 4 bytes
per object on a 64 bit system can add up fast on any sizable import.
As atom strings are strictly single components in a path name these
are probably limited to just 255 bytes by the underlying OS. Going
to that short of a string is probably too restrictive, but certainly
`unsigned int` is far too large for their lengths. `unsigned short`
is a reasonable limit.
Modes within a tree really only need two bytes to store their whole
value; using `unsigned int` here is vast overkill. Saving 4 bytes

with a large number of files.

* Announcement emails (via annotated tag creation) can be sent to a

* Output email is more verbose and generates specific content depending
on whether the ref is a tag, an annotated tag, a branch, or a
tracking branch
* The email is easier to filter; the subject line is prefixed with
[SCM] and a project description pulled from the "description" file
* It catches (and displays differently) branch updates that are

savings time from 1968 to 1971; it was permanently BST (+0100). That
means that on my computer the following is true:
$ date --date="1970-01-01 00:00" +"%F %T %z (%Z)"
1970-01-01 00:00:00 +0100 (BST)
This of course means that the --date argument to date is specified in
local time, not UTC. So when the hooks--update script does this:
date=$(date --date="1970-01-01 00:00:00 $ts seconds")
It's actually saying (in my timezone) "1970-01-01 01:00:00 UTC" + $ts.
Clearly this is wrong. The UNIX epoch started at midnight UTC not 1am
UTC.
This leads to the tagged time in hooks--update being shown as one hour
earlier than the true tagged time (in my timezone). The problem would
be worse for other timezones. For a +1300 timezone on 1970-01-01, the
tagged time would be 13 hours earlier. Oops.
The solution is to force the reference time to UTC, which is what this

$ date --date="1970-01-01 00:00 +0000" +"%F %T %z (%Z)"

Compute accurate distances in git-describe before output.
My prior change to git-describe attempts to print the distance
between the input commit and the best matching tag, but this distance
was usually only an estimate as we always aborted revision walking
as soon as we overflowed the configured limit on the number of
possible tags (as set by --candidates).
Displaying an estimated distance is not very useful and can just be
downright confusing. Most users (heck, most Git developers) don't
immediately understand why this distance differs from the output
of common tools such as `git rev-list | wc -l`. Even worse, the
estimated distance could change in the future (including decreasing
despite no rebase occuring) if we find more possible tags earlier
on during traversal. (This could happen if more tags are merged
into the branch between queries.) These factors basically make an
estimated distance useless.
Fortunately we are usually most of the way through an accurate
distance computation by the time we abort (due to reaching the
current --candidates limit). This means we can simply finish
counting out the revisions still in our commit queue to present
the accurate distance at the end. The number of commits remaining
in the commit queue is probably less than the number of commits
already traversed, so finishing out the count is not likely to take
very long. This final distance will then always match the output of
`git rev-list | wc -l`.
We can easily reduce the total number of commits that need to be
walked at the end by stopping as soon as all of the commits in the
commit queue are flagged as being merged into the already selected
best possible tag. If that's true then there are no remaining
unseen commits which can contribute to our best possible tag's
depth counter, so further traversal is useless.
Basic testing on my Mac OS X system shows there is no noticable
performance difference between this accurate distance counting
version of git-describe and the prior version of git-describe,
at least when run on git.git.

The first line has commit object name, the line number of the

Don't force everybody to call setup_ident().
Back when only handful commands that created commit and tag were
the only users of committer identity information, it made sense
to explicitly call setup_ident() to pre-fill the default value
from the gecos information. But it is much simpler for programs
to make the call automatic when get_ident() is called these days,

If abbrev is set to zero in git-describe, don't add the unique suffix
When on a non-tag commit, git-describe normally outputs descriptions of
the form
v1.0.0-g1234567890
Some scripts (for example the update hook script) might just want to
know the name of the nearest tag, so they then have to do
x=$(git-describe HEAD | sed 's/-g*//')
This is costly, but more importantly is fragile as it is relying on the
output format of git-describe, which we would then have to maintain
forever.
This patch adds support for setting the --abbrev option to zero. In
that case git-describe does as it always has, but outputs only the
nearest found tag instead of a completely unique name. This means that
scripts would not have to parse the output format and won't need
changing if the git-describe suffix is ever changed.

Allow non-developer to clone, checkout and fetch more easily.
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.

New files in git weren't being downloaded during CVS update
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.

Also add "git" to the pipe parameters, otherwise it does not work at all, as
no git commands are usable out of git context.

fsck-objects: refactor checking for connectivity
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
more useful.

git-gc: do not run git-prune by default.
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.

shallow repository: disable unsupported operations for now.
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.
