It makes "git reflog [show]" act as
git log -g --pretty=oneline --abbrev-cmit
and is fairly straightforward. So you can just write
git reflog
or
git reflog show
and it will show you the reflog in a nice format.

If the frontend asks us to checkpoint (via the explicit checkpoint
command) its probably because they are afraid the current import
will crash/fail/whatever and want to make sure they can pickup from
the last checkpoint. To do that sort of recovery, we will need the
current tip of every branch and tag available at the next startup.

Often users will be running fast-import from within a larger frontend
process, and this may be a frequent periodic tool such as a future
edition of `git-svn fetch`. We don't want to bombard users with our
large stats output if they won't be interested in it, so `--quiet`
is now an option to make gfi be more silent.

Some frontends may not be able to (easily) keep track of which files
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
path list on a per-commit basis.
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
care of. :)

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

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.
