I don't think people really follow the links or think very abstractly at
all in the first place.

So I was thinking more of some explicit examples. I actually think every
command should have an example in the man-page, and hey, here's a patch to
start things off.

Of course, I'm not exactly "Mr Documentation", and I don't know that this
is the prettiest way to do this, but I checked that the resulting html and
man-page seems at least reasonable.

And hey, if the examples look like each other, that's just because I'm
also not "Mr Imagination".

The require statement at the top of git-svnimport seems to confuse
rpmbuild dependency generation.  It uses the newer notation "v5.8.0",
and rpm ends up requiring "perl(v5.8.0)", while we would want it to
say something like "perl >= 0:5.008".

Ryan suggests old-style "require 5.008" might fix this problem, so
here it is.

Done in 0.99.9
==============

Ports
~~~~~

* Cygwin port [HPA].

* OpenBSD build [Merlyn and others].

Fixes
~~~~~

* clone request over git native protocol from a repository with
  too many refs did not work; this has been fixed.

* git-daemon got safer for kernel.org use [HPA].

* Extended SHA1 parser was not enforcing uniqueness for
  abbreviated SHA1; this has been fixed.

* http transport does not barf on funny characters in URL.

* The ref naming restrictions have been formalized and the
  coreish refuses to create funny refs; we still need to audit
  importers.  See git-check-ref-format(1).

New Features and Commands
~~~~~~~~~~~~~~~~~~~~~~~~~

* .git/config file as a per-repository configuration mechanism,
  and some commands understand it [Linus].  See
  git(7).

* The core.filemode configuration item can be used to make us a
  bit more FAT friendly.  See git(7).

* The extended SHA1 notation acquired Peel-the-onion operator
  ^{type} and ^{}.  See git-rev-parse(1).

* SVN importer [Matthias].  See git-svnimport(1).

* .git/objects/[0-9a-f]{2} directories are created on demand,
  and removed when becomes empty after prune-packed [Linus].

* Filenames output from various commands without -z option are
  quoted when they embed funny characters (TAB and LF) using
  C-style quoting within double-quotes, to match the proposed
  GNU diff/patch notation [me, but many people contributed in
  the discussion].

* git-mv is expected to be a better replacement for git-rename.
  While the latter has two parameter restriction, it acts more
  like the regular 'mv' that can move multiple things to one
  destinatino directory [Josef Weidendorfer].

* git-checkout can take filenames to revert the changes to
  them.  See git-checkout(1)

* The new program git-am is a replacement for git-applymbox that
  has saner command line options and a bit easier to use when a
  patch does not apply cleanly.

* git-ls-remote can show unwrapped onions using ^{} notation, to
  help Cogito to track tags.

* git-merge-recursive backend can merge unrelated projects.

* git-clone over native transport leaves the result packed.

* git-http-fetch issues multiple requests in parallel when
  underlying cURL library supports it [Nick and Daniel].

* git-fetch-pack and git-upload-pack try harder to figure out
  better common commits [Johannes].

* git-read-tree -u removes a directory when it makes it empty.

* git-diff-* records abbreviated SHA1 names of original and
  resulting blob; this sometimes helps to apply otherwise an
  unapplicable patch by falling back to 3-way merge.

* git-format-patch now takes series of from..to rev ranges and
  with '-m --stdout', writes them out to the standard output.
  This can be piped to 'git-am' to implement cheaper
  cherry-picking.

* git-tag takes '-u' to specify the tag signer identity [Linus].

* git-rev-list can take optional pathspecs to skip commits that
  do not touch them (--dense) [Linus].

* Comes with new and improved gitk [Paulus and Linus].

The client side support for multi_ack.
Signed-off-by: NJohannes Schindelin <Johannes.Schindelin@gmx.de>
Signed-off-by: NJunio C Hamano <junkio@cox.net>

This implements three things (trying very hard to be backwards
compatible):

It sends the "multi_ack" capability via the mechanism proposed by
Sergey Vlasov.

When the client sends "multi_ack" with at least one "want", multi_ack
is enabled.

When multi_ack is enabled, "continue" is appended to each "ACK" until
either the server can not store more refs, or "done" is received.

In contrast to the original protocol, as long as "continue" is sent,
flushes are answered by a "NAK" (not just until an "ACK" was sent),
and if "continue" was sent at least once, the last message is an
"ACK" without "continue".

This patch implements the client side of backward compatible upload-pack
protocol extension, <20051027141619.0e8029f2.vsu@altlinux.ru> by Sergey.

The updated server can append "server_capabilities" which is supposed
to be a string containing space separated features of the server, after
one of elements in the initial list of SHA1-refname line, hidden with
an embedded NUL.

After get_remote_heads(), check if the server supports the feature like

	if (server_supports("multi_ack"))
		do_something();

The next patches will extend the pack protocol. This test assures that this
extension is compatible to earlier versions of git-fetch-pack/git-upload-pack.

All you need to do to take advantage of this test, is to install older
known-to-be-working binaries in the path as "old-git-fetch-pack" and
"old-git-upload-pack".

Note that the warning when testing with old-git-fetch-pack is to be

of all the information which the server sent).

When git-fetch-pack gets the remote refs, it does not need to filter them
right away, but it can see which refs are common (taking advantage of the
patch which makes git-fetch-pack not use git-rev-list).

This means that we ask get_remote_heads() to return all remote refs,
including the funny refs, and filtering them with a separate function later.

The code used to call git-rev-list to enumerate the local revisions.
A disadvantage of that method was that git-rev-list, lacking a
control apart from the command line, would happily enumerate
ancestors of acknowledged common commits, which was just taking
unnecessary bandwidth.

Therefore, do not use git-rev-list on the fetching side, but rather
construct the list on the go. Send the revisions starting from the
local heads, ignoring the revisions known to be common.

This does two things:

 - we don't allow "." and ".." as components of a refname. Thus get_sha1()
   will not accept "./refname" as being the same as "refname" any more.

 - git-rev-parse stops doing revision translation after seeing a pathname,
   to match the brhaviour of all the tools (once we see a pathname,
   everything else will also be parsed as a pathname).

Basically, if you did

	git log *

and "gitk" was somewhere in the "*", we don't want to replace the filename
"gitk" with the SHA1 of the branch with the same name.

Of course, if there is any change of ambiguity, you should always use "--"
to make it explicit what are filenames and what are revisions, but this
makes the normal cases sane. The refname rule also means that instead of
the "--", you can do the same thing we're used to doing with filenames
that start with a slash: use "./filename" instead, and now it's a
filename, not an option (and not a revision).

So "git log ./*.c" is now actually a perfectly valid thing to do, even if
the first C-file might have the same name as a branch.

Trivial test:

	git-rev-parse gitk ./gitk gitk

should output something like

	9843c307
	./gitk
	gitk

where the "./gitk" isn't seen as a revision, and the second "gitk" is a
filename simply because we've seen filenames already, and thus stopped
doing revision parsing.

The git philosophy when it comes to disk accesses is "Laugh in the face of
danger".

Notably, since we never modify an existing object, we don't really care
that deeply about flushing things to disk, since even if the machine
crashes in the middle of a git operation, you can never really have lost
any old work. At most, you'd need to figure out the proper heads (which
git-fsck-objects can do for you) and re-do the operation.

However, there's two exceptions to this: pruning and repacking. Those
operations will actually _delete_ old objects that they know about in
other ways (ie that they just repacked, or that they have found in other
places).

However, since they actually modify old state, we should thus be a bit
more careful about them. If the machine crashes and the duplicate new
objects haven't been flushed to disk, you can actually be in trouble.

This is trivially stupid about it by calling "sync" before removing the
objects. Not very smart, but we're talking about special operations than
are usually done once a week if that.
