Linus Torvalds 2f82f760e1 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.

Linus Torvalds 1211be6bed Make thin-pack generation subproject aware.
When a thin pack wants to send a tree object at "sub/dir", and
the commit that is common between the sender and the receiver
that is used as the base object has a subproject at that path,
we should not try to use the data at "sub/dir" of the base tree
as a tree object.  It is not a tree to begin with, and more
importantly, the commit object there does not have to even
exist.

Shawn O. Pearce 95064cbcc8 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.

Shawn O. Pearce 904b194151 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.

Shawn O. Pearce 8acb3297f3 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.

Shawn O. Pearce ac053c0202 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.

Shawn O. Pearce 1fdb649c6a 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.

Shawn O. Pearce 2c570cde98 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.

Shawn O. Pearce 401d53fa35 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.

Shawn O. Pearce ea08a6fd19 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).

René Scharfe 6d2d9e8666 diff: squelch empty diffs even more
When we compare two non-tracked files, or explicitly
specify --no-index, the suggestion to run git-status
is not helpful.

The patch adds a new diff_options bitfield member, no_index, that
is used instead of the special value of -2 of the rev_info field
max_count to indicate that the index is not to be used.  This makes
it possible to pass that flag down to diffcore_skip_stat_unmatch(),
which only has one diff_options parameter.

This could even become a cleanup if we removed all assignments of
max_count to a value of -2 (viz. replacement of a magic value with
a self-documenting field name) but I didn't dare to do that so late
in the rc game..

The no_index bit, if set, then tells diffcore_skip_stat_unmatch()
to not account for any skipped stat-mismatches, which avoids the
suggestion to run git-status.

Marco Costalba 9fa3465d6b Add --log-size to git log to print message size
With this option git-log prints log message size
just before the corresponding message.

Porcelain tools could use this to speedup parsing
of git-log output.

Note that size refers to log message only. If also
patch content is shown its size is not included.

In case it is not possible to know the size upfront
size value is set to zero.
