...
If fast-import is being used to update an existing branch of
a repository, the user may not want to lose commits if another
process updates the same ref at the same time. For example, the
user might be using fast-import to make just one or two commits
against a live branch.
We now perform a fast-forward check during the ref updating process.
If updating a branch would cause commits in that branch to be lost,
we skip over it and display the new SHA1 to standard error.
This new default behavior can be overridden with `--force`, like
git-push and git-fetch.

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.

Corrected a couple of header markup lines which were shorter than the
actual header, and made the `data` commands two formats into a named
list, which matches how we document the two formats of the `M` command
within a commit.
Also tried to simplify the language about our decimal integer format;
Linus pointed out I was probably being too specific at the cost of

The --branch-log option and its associated code hasn't been used in
several months, as its not really very useful for debugging fast-import
or a frontend. I don't plan on supporting it in this state long-term,

This is a first pass at the manpage for git-fast-import.
I have tried to cover the input format in extreme detail, creating a
reference which is more detailed than the BNF grammar appearing in
the header of fast-import.c. I have also covered some details about
gfi's performance and memory utilization, as well as the average
learning curve required to create a gfi frontend application (as it
is far lower than it might appear on first glance).
The documentation still lacks real example input streams, which may
turn out to be difficult to format in asciidoc due to the blank lines
which carry meaning within the format.

This particular use of git-rebase to remove a single commit or a
range of commits from the history of a branch recently came up on
the mailing list. Documenting the example should help other users
arrive at the same solution on their own.
It also was not obvious to the newcomer that git-rebase is able to
accept any commit for --onto <newbase> and <upstream>. We should
at least minimally document this, as much of the language in
git-rebase's manpage refers to 'branch' rather than 'committish'.

I was reading the tutorial and noticed that we say this:
Also, don't use "git reset" on a publicly-visible branch that
other developers pull from, as git will be confused by history
that disappears in this way.
I do not think this is a good explanation. For example, if we
do this:
(1) I build a series and push it out.
---o---o---o---j
(2) Alice clones from me, and builds two commits on top of it.
---o---o---o---j---a---a
(3) I rewind one and build a few, and push them out.
---o---o---o...j
\
h---h---h---h
(4) Alice pulls from me again:
---o---o---o---j---a---a---*
\ /
h---h---h---h
Contrary to the description, git will happily have Alice merge
between the two branches, and never gets confused.
Maybe I did not want to have 'j' because it was an incomplete
solution to some problem, and Alice may have fixed it up with
her changes, while I abandoned that approach I started with 'j',
and worked on something completely unrelated in the four 'h'
commits. In such a case, the merge Alice would make would be
very sensible, and after she makes the merge if I pull from her,
the world will be perfect. I started something with 'j' and
dropped the ball, Alice picked it up and perfected it while I
went on to work on something else with 'h'. This would be a
perfect example of distributed parallel collaboration. There is
nothing confused about it.
The case the rewinding becomes problematic is if the work done
in 'h' tries to solve the same problem as 'j' tried to solve in
a different way. Then the merge forced on Alice would make her
pick between my previous attempt with her fixups (j+a) and my
second attempt (h). If 'a' commits were to fix up what 'j'
started, presumably Alice already studied and knows enough about
the problem so she should be able to make an informed decision
to pick between what 'j+a' and 'h' do.
A lot worse case is if Alice's work is not at all related to
what 'j' wanted to do (she did not mean to pick up from where I
left off -- she just wanted to work on something different).
Then she would not be familiar enough with what 'j' and 'h'
tried to achieve, and I'd be forcing her to pick between the
two. Of course if she can make the right decision, then again
that is a perfect example of distributed collaboration, but that
does not change the fact that I'd be forcing her to clean up my
mess.

failed to sign the tag with GPG.

$ gpg --list-keys andy

So when git-tag looks for "Andy Parkins <andyparkins@gmail.com>";
obviously it's not going to be found.
There shouldn't be a requirement that I use the same form of my name in
my git repository and my gpg key - I might want to be formal (Andrew) in
my gpg key and informal (Andy) in the repository. Further I might have
multiple keys in my keyring, and might want to use one that doesn't
match up with the address I use in commit messages.
This patch adds a configuration entry "user.signingkey" which, if
present, will be passed to the "-u" switch for gpg, allowing the tag
signing key to be overridden. If the entry is not present, the fallback
is the original method, which means existing behaviour will continue
untouched.

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

the downloaded pack as before.

configuration. We might want to introduce transfer.unpacklimit

Then I cherry-picked @{9}~2 to create @{3} (the log message

When we are on a detached HEAD, there is no current branch.
There is no reason to leak the error messages to the end user
since this is a situation we expect to see.
This adds -q option to git-symbolic-ref to exit without issuing
an error message if the given name is not a symbolic ref.
By the way, with or without this patch, there currently is no
good way to tell failure modes between "git symbolic-ref HAED"
and "git symbolic-ref HEAD". Both says "is not a symbolic ref".
We may want to do something about it.

My prior version of git-describe ran very slowly on even reasonably
sized projects like git.git and linux.git as it tended to identify
a large number of possible tags and then needed to generate the
revision list for each of those tags to sort them and select the
best tag to describe the input commit.
All we really need is the number of commits in the input revision
which are not in the tag. We can generate these counts during
the revision walking and tag matching loop by assigning a color to
each tag and coloring the commits as we walk them. This limits us
to identifying no more than 26 possible tags, as there is limited
space available within the flags field of struct commit.
The limitation of 26 possible tags is hopefully not going to be a
problem in real usage, as most projects won't create 26 maintenance
releases and merge them back into a development trunk after the
development trunk was tagged with a release candidate tag. If that
does occur git-describe will start to revert to its old behavior of
using the newer maintenance release tag to describe the development
trunk, rather than the development trunk's own tag. The suggested
workaround would be to retag the development trunk's tip.
However since even 26 possible tags can take a while to generate a
description for on some projects I'm defaulting the limit to 10 but
offering the user --candidates to increase the number of possible
matches if they need a more accurate result. I specifically chose
10 for the default as it seems unlikely projects will have more
than 10 maintenance releases merged into a development trunk before
retagging the development trunk, and it seems to perform about the
same on linux.git as v1.4.4.4 git-describe.
A large amount of debugging information was also added during
the development of this change, so I've left it in to be toggled
on with --debug. It may be useful to the end user to help them
understand why git-describe took one particular tag over another.

The goals are:
- Readable from beginning to end in order without having read
any other git documentation beforehand.
- Helpful section names and cross-references, so it's not too
hard to skip around some if you need to.
- Organized to allow it to grow much larger (unlike the
tutorials)
It's more liesurely than tutorial.txt, but tries to stay focused on
practical how-to stuff. It adds a discussion of how to resolve merge
conflicts, and partial instructions on setting up and dealing with a
public repository.
I've lifted a little bit from "branching and merging" (e.g., some of the
discussion of history diagrams), and could probably steal more if that's
OK. (Similarly anyone should of course feel free to reuse bits of this
if any parts seem more useful than the whole.)
There's a lot of detail on managing branches and using git-fetch, just
because those are essential even to people needing read-only access
(e.g., kernel testers). I think those sections will be much shorter
once the new "git remote" command and the disconnected checkouts are
taken into account.
I do feel bad about adding yet another piece of documentation, but I we
need something that goes through all the basics in a logical order, and
I wasn't seeing how to grow the tutorials into that.

This finally turns on the sliding window behavior for packfile data
access by mapping limited size windows and chaining them under the
packed_git->windows list.
We consider a given byte offset to be within the window only if there
would be at least 20 bytes (one hash worth of data) accessible after
the requested offset. This range selection relates to the contract
that use_pack() makes with its callers, allowing them to access
one hash or one object header without needing to call use_pack()
for every byte of data obtained.
In the worst case scenario we will map the same page of data twice
into memory: once at the end of one window and once again at the
start of the next window. This duplicate page mapping will happen
only when an object header or a delta base reference is spanned
over the end of a window and is always limited to just one page of
duplication, as no sane operating system will ever have a page size
smaller than a hash.
I am assuming that the possible wasted page of virtual address
space is going to perform faster than the alternatives, which
would be to copy the object header or ref delta into a temporary
buffer prior to parsing, or to check the window range on every byte
during header parsing. We may decide to revisit this decision in
the future since this is just a gut instinct decision and has not
actually been proven out by experimental testing.

Rather than hardcoding the maximum number of bytes which can be
mmapped from pack files we should make this value configurable,
allowing the end user to increase or decrease this limit on a
per-repository basis depending on the size of the repository
and the capabilities of their operating system.
In general users should not need to manually tune such a low-level
setting within the core code, but being able to artifically limit
the number of bytes which we can mmap at once from pack files will
make it easier to craft test cases for the new mmap sliding window
implementation.

Junio rightly pointed out that the --reflog-action parameter
was starting to get out of control, as most porcelain code

At Junio's suggestion we are introducing the new set_reflog_action
function to all shell scripts, allowing them to declare early on
what their default reflog name should be, but this setting only
takes effect if the caller has not already set the GIT_REFLOG_ACTION

It is plausible for somebody to want to view the commit log in a
different encoding from i18n.commitencoding -- the project's
policy may be UTF-8 and the user may be using a commit message
hook to run iconv to conform to that policy (and either not have
i18n.commitencoding to default to UTF-8 or have it explicitly
set to UTF-8). Even then, Latin-1 may be more convenient for
the usual pager and the terminal the user uses.
The new variable i18n.logoutputencoding is used in preference to
i18n.commitencoding to decide what encoding to recode the log
output in when git-log and friends formats the commit log message.
