A comment on top of create_tmpfile() describes caveats ('can have
problems on various systems (FAT, NFS, Coda)') that should apply
in this situation as well. This in the end did not end up solving
any of my personal problems, but it might be a useful cleanup patch
nevertheless.

Currently fast-import/export cannot be used for
repositories with submodules. This patch extends
the relevant programs to make them correctly
process gitlinks.
Links can be represented by two forms of the
Modify command:
M 160000 SHA1 some/path
which sets the link target explicitly, or
M 160000 :mark some/path
where the mark refers to a commit. The latter
form can be used by importing tools to build
all submodules simultaneously in one physical
repository, and then simply fetch them apart.

When you misuse a git command, you are shown the usage string.
But this is currently shown in the dashed form. So if you just
copy what you see, it will not work, when the dashed form
is no longer supported.
This patch makes git commands show the dash-less version.
For shell scripts that do not specify OPTIONS_SPEC, git-sh-setup.sh
generates a dash-less usage string now.

Creating a branch in fast-import and then resetting it without making
any further commits to it currently causes an error message at the
end of the import.
This error is triggered by cvs2svn's git backend, which uses a
temporary fixup branch when it creates tags, because the fixup branch
is reset after each tag.
This patch prevents the error, allowing "reset" to be used to delete
temporary branches.

cmd_from() ends with a call to read_next_command(), which is needed
when using cmd_from() from commands where from is not the last element.
With reset, however, "from" is the last command, after which the flow
returns to the main loop, which calls read_next_command() again.
Because of this, always set unread_command_buf in cmd_reset_branch(),
even if cmd_from() was successful.
Add a test case for this in t9300-fast-import.sh.

If fast-import is in the middle of crashing due to a protocol error
or something like that then it can be very useful to have the mark
table and all objects up until that point be available for a new
import to resume from.
Currently we just close the active packfile, unkeep all of our
newly created packfiles (so they can be deleted), and dump the
marks table to a temporary file.
We don't attempt to update the refs/tags that the process has in
memory as much of that data can be found in the crash report and I'm
not sure it would be the right thing to do under every type of crash.

the delta did not apply correctly or was not able to be decompressed

We now use the configured pack.compression and pack.depth values
within fast-import, as like builtin-pack-objects fast-import is
generating a packfile for consumption by the Git tools.
We use the same behavior as builtin-pack-objects does for these
options, allowing core.compression to supply the default value
for pack.compression.
The default setting for pack.depth within fast-import is still 10
as users will generally repack fast-import generated packfiles by
`repack -f`. A large delta depth within the fast-import packfile
can significantly slow down such a later repack.

fast-import was relying on the fact that on most systems mmap() and
write() are synchronized by the filesystem's buffer cache. We were
relying on the ability to mmap() 20 bytes beyond the current end
of the file, then later fill in those bytes with a future write()
call, then read them through the previously obtained mmap() address.
This isn't always true with some implementations of NFS, but it is
especially not true with our NO_MMAP=YesPlease build time option used
on some platforms. If fast-import was built with NO_MMAP=YesPlease
we used the malloc()+pread() emulation and the subsequent write()
call does not update the trailing 20 bytes of a previously obtained
"mmap()" (aka malloc'd) address.
Under NO_MMAP that behavior causes unpack_entry() in sha1_file.c to
be unable to read an object header (or data) that has been unlucky
enough to be written to the packfile at a location such that it
is in the trailing 20 bytes of a window previously opened on that
same packfile.
This bug has gone unnoticed for a very long time as it is highly data
dependent. Not only does the object have to be placed at the right
position, but it also needs to be positioned behind some other object
that has been accessed due to a branch cache invalidation. In other
words the stars had to align just right, and if you did run into
this bug you probably should also have purchased a lottery ticket.
Fortunately the workaround is a lot easier than the bug explanation.
Before we allow unpack_entry() to read data from a pack window
that has also (possibly) been modified through write() we force
all existing windows on that packfile to be closed. By closing
the windows we ensure that any new access via the emulated mmap()
will reread the packfile, updating to the current file content.
This comes at a slight performance degredation as we cannot reuse
previously cached windows when we update the packfile. But it
is a fairly minor difference as the window closes happen at only
two points:
- When the packfile is finalized and its .idx is generated:
At this stage we are getting ready to update the refs and any
data access into the packfile is going to be random, and is
going after only the branch tips (to ensure they are valid).
Our existing windows (if any) are not likely to be positioned
at useful locations to access those final tip commits so we
probably were closing them before anyway.
- When the branch cache missed and we need to reload:
At this point fast-import is getting change commands for the next
commit and it needs to go re-read a tree object it previously
had written out to the packfile. What windows we had (if any)
are not likely to cover the tree in question so we probably were
closing them before anyway.
We do try to avoid unnecessarily closing windows in the second case
by checking to see if the packfile size has increased since the
last time we called unpack_entry() on that packfile. If the size
has not changed then we have not written additional data, and any
existing window is still vaild. This nicely handles the cases where
fast-import is going through a branch cache reload and needs to read
many trees at once. During such an event we are not likely to be
updating the packfile so we do not cycle the windows between reads.
With this change in place t9301-fast-export.sh (which was broken
by c3b0dec509fe136c5417422f31898b5a4e2d5e02) finally works again.

Brian Downing noticed fast-import can produce tree depths of up
to 6,035 objects and even deeper. Long delta chains can create
very small packfiles but cause problems during repacking as git
needs to unpack each tree to count the reachable blobs.
What's happening here is the active branch cache isn't big enough.
We're swapping out the branch and thus recycling the tree information
(struct tree_content) back into the free pool. When we later reload
the tree we set the delta_depth to 0 but we kept the tree we just
reloaded as a delta base.
So if the tree we reloaded was already at the maximum depth we
wouldn't know it and make the new tree a delta. Multiply the
number of times the branch cache has to swap out the tree times
max_depth (10) and you get the maximum delta depth of a tree created
by fast-import. In Brian's case above the active branch cache had
to swap the branch out 603/604 times during this import to produce
a tree with a delta depth of 6035.

For that purpose, the ->buf is always initialized with a char * buf living
in the strbuf module. It is made a char * so that we can sloppily accept
things that perform: sb->buf[0] = '\0', and because you can't pass "" as an
initializer for ->buf without making gcc unhappy for very good reasons.
strbuf_init/_detach/_grow have been fixed to trust ->alloc and not ->buf
anymore.
as a consequence strbuf_detach is _mandatory_ to detach a buffer, copying
->buf isn't an option anymore, if ->buf is going to escape from the scope,
and eventually be free'd.
API changes:
* strbuf_setlen now always works, so just make strbuf_reset a convenience
macro.
* strbuf_detatch takes a size_t* optional argument (meaning it can be
NULL) to copy the buffer's len, as it was needed for this refactor to
make the code more readable, and working like the callers.

read_line is now strbuf_getline, and is a first class citizen, it returns 0
when reading a line worked, EOF else.
The ->eof marker was used non-locally by fast-import.c, mimic the same

The gory details are explained in strbuf.h. The change of semantics this
patch enforces is that the embeded buffer has always a '\0' character after
its last byte, to always make it a C-string. The offs-by-one changes are all
related to that very change.
A strbuf can be used to store byte arrays, or as an extended string
library. The `buf' member can be passed to any C legacy string function,
because strbuf operations always ensure there is a terminating \0 at the end
of the buffer, not accounted in the `len' field of the structure.
A strbuf can be used to generate a string/buffer whose final size is not
really known, and then "strbuf_detach" can be used to get the built buffer,
and keep the wrapping "strbuf" structure usable for further work again.
Other interesting feature: strbuf_grow(sb, size) ensure that there is
enough allocated space in `sb' to put `size' new octets of data in the
buffer. It helps avoiding reallocating data for nothing when the problem the
strbuf helps to solve has a known typical size.

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.

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.

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.

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.

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.

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.
