"format-patch --root rev" is the way to show everything.
We used to trigger the special case "things not in origin"

no number (e.g. "git format-patch -4 origin") was specified, and

This narrows the special case a bit more, by making:

git-merge: do up-to-date check also for all strategies
This clarifies the logic to omit fast-forward check and omit
trivial merge before running the specified strategy.
The "index_merge" variable started out as a flag to say "do not
do anything clever", but when recursive was changed to skip the
trivial merge, the semantics were changed and the variable alone
does not make sense anymore.
This splits the variable into two, allow_fast_forward (which is
almost always true, and avoids making a merge commit when the
other commit is a descendant of our branch, but is set to false
for ours and subtree) and allow_trivial_merge (which is false
for ours, recursive and subtree).
Unlike the earlier implementation, the "ours" strategy allows an
up-to-date condition. When we are up-to-date, the result will
be our commit, and by definition, we will have our tree as the

Fix initialization of a bare repository
Here is my attempt to fix this with a minimally intrusive patch.
* As "git --bare init" cannot tell if it was called with --bare or
just "GIT_DIR=. git init", I added an explicit assignment of
is_bare_repository_cfg on the codepath for "git --bare".
* GIT_WORK_TREE alone without GIT_DIR does not make any sense,
nor GIT_WORK_TREE with an explicit "git --bare". Catch that
mistake. It might make sense to move this check to "git.c"
side as well, but I tried to shoot for the minimum change for
now.
* Some scripts, especially from the olden days, rely on
traditional GIT_DIR behaviour in "git init". Namely, these
are some notable patterns:
(create a bare repository)
- mkdir some.git && cd some.git && GIT_DIR=. git init
- mkdir some.git && cd some.git && git --bare init
This comes with a new test script and also passes the existing
test suite, but there may be cases that are still broken with
the current tip of master and this patch does not yet fix. I'd
appreciate help in straightening this mess out.

git-gui: Correct 'git gui blame' in a subdirectory
David Kastrup pointed out that the following sequence was not
working as we had intended:
$ cd lib
$ git gui blame console.tcl
fatal: cannot stat path lib/console.tcl: No such file or directory
The problem here was we disabled the chdir to the root of the
working tree when we are running with a "bare allowed" feature
such as blame or browser, but we still kept the prefix we found via
`git rev-parse --show-prefix`. This caused us to try and look for
the file "console.tcl" within the subdirectory but also include
the subdirectory's own path from the root of the working tree.
This is unlikely to succeed, unless the user just happened to have
a "lib/lib/console.tcl" file in the repository, in which case we
would produce the wrong result.
In the case of a bare repository we shouldn't get back a value from
`rev-parse --show-prefix`, so really $_prefix should only be set
to the non-empty string if we are in a working tree and we are in a
subdirectory of that working tree. If this is true we really want
to always be at the top level of the working tree, as all paths are
accessed as though they were relative to the top of the working tree.

obscured by another window in the same panel. So we need to keep
track of whether or not the root window has been displayed for this
application, and once it has been we cannot ever assume that ismapped

Take binary diffs into account for "git rebase"
We used to not generate a patch ID for binary diffs, but that means that
some commits may be skipped as being identical to already-applied diffs
when doing a rebase.
So just delete the code that skips the binary diff. At the very least,
we'd want the filenames to be part of the patch ID, but we might also want
to generate some hash for the binary diff itself too.
This fixes an issue noticed by Torgil Svensson.

Correct documentation of 'reflog show' to explain it shows HEAD
By default 'git reflog show' will show the reflog of 'HEAD' and not
the reflog of the current branch. This is most likely due to the
work done a while ago as part of the detached HEAD series to allow
HEAD to have its own reflog independent of each branch's reflog.
Since 'git reflog show' is really just an obscure alias for 'git
log -g --abbrev-commit --pretty=oneline' it should behave the same
way and its documentation should match.

Include recent command history in fast-import crash reports
When we crash the frontend developer (or end-user) may need to know
roughly around what part of the input stream we had a problem with
and aborted on. Because line numbers aren't very useful in this
sort of application we instead just keep the last 100 commands in
a FIFO queue and print them as part of the crash report.
Currently one problem with this design is a commit that has
more than 100 modified files in it will flood the FIFO and any
context regarding branch/from/committer/mark/comments will be lost.
We really should save only the last few (10?) file changes for the
current commit, ensuring we have some prior higher level commands
in the FIFO when we crash on a file M/D/C/R command.
Another issue with this approach is the FIFO only includes the
commands, it does not include the commit messages. Yet having a
commit message may be useful to help locate the relevant change in
the source material. In practice I don't think this is going to be a
major concern as the frontend can always embed its own source change
set identifier as a comment (which will appear in the crash report)
and the commit message(s) for the most recent commits of any given
branch should be obtainable from the (packed) commit objects.

Generate crash reports on die in fast-import
As fast-import is quite strict about its input and die()'s anytime
something goes wrong it can be difficult for a frontend developer
to troubleshoot why fast-import rejected their input, or to even
determine what input command it rejected.
This change introduces a custom handler for Git's die() routine.
When we receive a die() for any reason (fast-import or a lower level
core Git routine we called) the error is first dumped onto stderr
and then a more extensive crash report file is prepared in GIT_DIR.
Finally we exit the process with status 128, just like the stock
builtin die handler.
An internal flag is set to prevent any further die()'s that may be
invoked during the crash report generator from causing us to enter
into an infinite loop. We shouldn't die() from our crash report
handler, but just in case someone makes a future code change we are
prepared to gaurd against small mistakes turning into huge problems
for the end-user.

Allow frontends to bidirectionally communicate with fast-import
The existing checkpoint command is very useful to force fast-import
to dump the branches out to disk so that standard Git tools can
access them and the objects they refer to. However there was not a
way to know when fast-import had finished executing the checkpoint
and it was safe to read those refs.
The progress command can be used to make fast-import output any
message of the frontend's choosing to standard out. The frontend
can scan for these messages using select() or poll() to monitor a
pipe connected to the standard output of fast-import.

Make trailing LF optional for all fast-import commands
For the same reasons as the prior change we want to allow frontends
to omit the trailing LF that usually delimits commands. In some
cases these just make the input stream more verbose looking than
it needs to be, and its just simpler for the frontend developer to
get started if our parser is slightly more lenient about where an
LF is required and where it isn't.
To make this optional LF feature work we now have to buffer up to one
line of input in command_buf. This buffering can happen if we look
at the current input command but don't recognize it at this point
in the code. In such a case we need to "unget" the entire line,
but we cannot depend upon the stdio library to let us do ungetc()
for that many characters at once.

Make trailing LF following fast-import `data` commands optional
A few fast-import frontend developers have found it odd that we
require the LF following a `data` command, especially in the exact
byte count format. Technically we don't need this LF to parse
the stream properly, but having it here does make the stream more
readable to humans. We can easily make the LF optional by peeking
at the next byte available from the stream and pushing it back into
the buffer if its not LF.

Teach fast-import to ignore lines starting with '#'
Several frontend developers have asked that some form of stream
comments be permitted within a fast-import data stream. This way
they can include information from their own frontend program about
where specific data was taken from in the source system, or about
a decision that their frontend may have made while creating the
fast-import data stream.
This change introduces comments in the Bourne-shell/Tcl/Perl style.
Lines starting with '#' are ignored, up to and including the LF.
Unlike the above mentioned three languages however we do not look for
and ignore leading whitespace. This just simplifies the definition
of the comment format and the code that parses them.
To make comments work we had to stop using read_next_command() within
cmd_data() and directly invoke read_line() during the inline variant
of the function. This is necessary to retain any lines of the
input data that might otherwise look like a comment to fast-import.

Actually allow TAG_FIXUP branches in fast-import
Michael Haggerty <mhagger@alum.mit.edu> noticed while debugging a
Git backend for cvs2svn that fast-import was barfing when he tried
to use "TAG_FIXUP" as a branch name for temporary work needed to
cleanup the tree prior to creating an annotated tag object.
The reason we were rejecting the branch name was check_ref_format()
returns -2 when there are less than 2 '/' characters in the input
name. TAG_FIXUP has 0 '/' characters, but is technically just as
valid of a ref as HEAD and MERGE_HEAD, so we really should permit it
(and any other similar looking name) during import.
New test cases have been added to make sure we still detect very
wrong branch names (e.g. containing [ or starting with .) and yet
still permit reasonable names (e.g. TAG_FIXUP).
