f1000898d4 Start defining a more sophisticated run_command
There are a number of places where we do some variation of
fork()+exec() but we also need to setup redirection in the process,
much like what run_command does for us already with its option flags.

It would be nice to reuse more of the run_command logic, especially
as that non-fork API helps us to port to odd platforms like Win32.

497bdc88d6 Switch to run_command_v_opt in revert
Another change by me is removing the va_list variants of run_command,
one of which is used by builtin-revert.c.  To avoid compile errors
I'm refactoring builtin-revert to use the char** variant instead,
as that variant is staying.

ed8ad7e2e2 I like the idea of the new ':/<oneline prefix>' notation, and gave it
a try, but all I could get was a segfault.  It was dereferencing a NULL
commit list.  Fix below.  With it, this example now works:

    $ mkdir .j; cd .j; touch f
    $ git-init; git-add f; git-commit -mc f; echo x >f; git-commit -md f

1dc71a9155 user-manual: fix rendering of history diagrams
Asciidoc appears to interpret a backslash at the end of a line as
escaping the end-of-line character, which screws up the display of
history diagrams like

 o--o--o
	\
	 o--...

The obvious fix (replacing "\" by "\\") doesn't work.  The only
workaround I've found is to include all such diagrams in a LiteralBlock.
Asciidoc claims that should be equivalent to a literal paragraph, so I
don't understand why the difference--perhaps it's an asciidoc bug.

c816eb1784 glossary: fix overoptimistic automatic linking of defined terms
The script sort_glossary.pl turns each use of "term" into a link to the
definition of "term".  To avoid mangling links like

	gitlink:git-term[1]

it doesn't replace any occurence of "term" preceded by "link:git-".
This fails for gitlink:git-symbolic-ref[1] when substituting for "ref".

So instead just refuse to replace anything preceded by a "-".
That could result in missing some opportunities, but that's a less
annoying error.

Actually I find the automatic substitution a little distracting; some
day maybe we should just run it once and commit the result, so it can
be hand-tuned.

60b9004cdb Use atomic updates to the fast-import mark file
When we allow fast-import frontends to reload a mark file from a
prior session we want to let them use the same file as they exported
the marks to.  This makes it very simple for the frontend to save
state across incremental imports.

But we don't want to lose the old marks table if anything goes wrong
while writing our current marks table.  So instead of truncating and
overwriting the path specified to --export-marks we use the standard
lockfile code to write the current marks out to a temporary file,
then rename it over the old marks table.

05ef58ec1f Teach receive-pack to run pre-receive/post-receive hooks
Bill Lear pointed out that it is easy to send out notifications of
changes with the update hook, but successful execution of the update
hook does not necessarily mean that the ref was actually updated.
Lock contention on the ref or being unable to append to the reflog
may prevent the ref from being changed.  Sending out notifications
prior to the ref actually changing is very misleading.

To help this situation I am introducing two new hooks to the
receive-pack flow: pre-receive and post-receive.  These new hooks
are invoked only once per receive-pack execution and are passed
three arguments per ref (refname, old-sha1, new-sha1).

The new post-receive hook is ideal for sending out notifications,
as it has the complete list of all refnames that were successfully
updated as well as the old and new SHA-1 values.  This allows more
interesting notifications to be sent.  Multiple ref updates could
be easily summarized into one email, for example.

The new pre-receive hook is ideal for logging update attempts, as it
is run only once for the entire receive-pack operation.  It can also
be used to verify multiple updates happen at once, e.g. an update
to the `maint` head must also be accompained by a new annotated tag.

Lots of documentation improvements for receive-pack are included
in this change, as we want to make sure the new hooks are clearly
explained.

8aaf7d6410 Refactor handling of error_string in receive-pack
I discovered we did not send an ng line in the report-status feedback
if the ref was not updated because the repository has the config
option receive.denyNonFastForwards enabled.  I think the reason this
happened is that it is simply too easy to forget to set error_string
when returning back a failure from update()

We now return an ng line for a non-fastforward update, which in
turn will cause send-pack to exit with a non-zero exit status.
Hence the modified test.

This refactoring changes update to return a const char* describing
the error, which execute_commands always loads into error_string.
The result is what I think is cleaner code, and allows us to
initialize the error_string member to NULL when we read_head_info.

I want error_string to be NULL in all commands before we call
execute_commands, so that we can reuse the run_hook function to
execute a new pre-receive hook.

c8dd277109 Refactor run_update_hook to be more useful
This is a simple refactoring of run_update_hook to allow the function
to be passed the name of the hook it runs and also to build the
argument list from a list of struct commands, rather than just one
struct command.

The refactoring is to support new pre-receive and post-receive
hooks that will be given the entire list of struct commands,
rather than just one struct command.  These new hooks will follow
in another patch.

93e72d8d8f Preallocate memory earlier in fast-import
I'm about to teach fast-import how to reload the marks file created
by a prior session.  The general approach that I want to use is to
immediately parse the marks file when the specific argument is found
in argv, thereby allowing the caller to supply multiple marks files,
as the mark space can be sparsely populated.

To make that work out we need to allocate our object tables before
we parse the command line options.  Since none of these tables
depend on the command line options, we can easily relocate them.

dc49cd769b Cast 64 bit off_t to 32 bit size_t
Some systems have sizeof(off_t) == 8 while sizeof(size_t) == 4.
This implies that we are able to access and work on files whose
maximum length is around 2^63-1 bytes, but we can only malloc or
mmap somewhat less than 2^32-1 bytes of memory.

On such a system an implicit conversion of off_t to size_t can cause
the size_t to wrap, resulting in unexpected and exciting behavior.
Right now we are working around all gcc warnings generated by the
-Wshorten-64-to-32 option by passing the off_t through xsize_t().

In the future we should make xsize_t on such problematic platforms
detect the wrapping and die if such a file is accessed.

c4001d92be Use off_t when we really mean a file offset.
Not all platforms have declared 'unsigned long' to be a 64 bit value,
but we want to support a 64 bit packfile (or close enough anyway)
in the near future as some projects are getting large enough that
their packed size exceeds 4 GiB.

By using off_t, the POSIX type that is declared to mean an offset
within a file, we support whatever maximum file size the underlying
operating system will handle.  For most modern systems this is up
around 2^60 or higher.

7cadf491c6 Use uint32_t for pack-objects counters.
As we technically try to support up to a maximum of 2**32-1 objects
in a single packfile we should act like it and use unsigned 32 bit
integers for all of our object counts and progress output.

This change does not modify everything in pack-objects that probably
needs to change to fully support the maximum of 2**32-1 objects.
I'm intentionally breaking the improvements into slightly smaller
commits to make them easier to follow.

No logic change should be occuring here, with the exception that
some comparsions will now work properly when the number of objects
exceeds 2**31-1.

3a55602eec General const correctness fixes
We shouldn't attempt to assign constant strings into char*, as the
string is not writable at runtime.  Likewise we should always be
treating unsigned values as unsigned values, not as signed values.

Most of these are very straightforward.  The only exception is the
(unnecessary) xstrdup/free in builtin-branch.c for the detached
head case.  Since this is a user-level interactive type program
and that particular code path is executed no more than once, I feel
that the extra xstrdup call is well worth the easy elimination of
this warning.

d9cb5399ee git-archimport: allow remapping branch names
This patch adds support to archimport for remapping the branch
names to match those used in git more closely.  This is useful
for projects that migrate to git (as opposed to users that want
to use git on Arch-based projects).  For example, one can choose
an Arch branch name and call it "master".

The new command-line syntax works even if there is a colon in
a branch name, since only the part after the last colon is taken
to be the git name (git does not allow colons in branch names).

The new feature is implemented so that archives rotated every
year can also be remapped into a single git archive.

There is no need to escape HTML tag's attributes in CGI.pm
HTML methods (like CGI::a()), because CGI.pm does attribute
escaping automatically.

  $cgi->a({ ... -attribute => atribute_value }, tag_contents)

is translated to

  <a ... attribute="attribute_value">tag_contents</a>

The rules for escaping attribute values (which are string contents) are
different. For example you have to take care about escaping embedded '"'
and "'" characters; CGI::a() does that for us automatically.

CGI::a() does not HTML escape tag_contents; we would need to write

  <a href="URL">some <b>bold</b> text</a>

for example. So we use esc_html (or esc_path) to escape tag_contents
as needed.
