git-proxy updates.

This builds on top of the git-proxy mechanism Paul Collins did,
and updates its configuration mechanism.

 * GIT_PROXY_COMMAND environment variable is used as the
   catch-all fallback, as in the original.  This has not
   changed.

 * Renames proxy configuration variables to core.gitproxy; this
   has become a multi-value variable per list discussion, most
   notably from suggestion by Linus.

[core]
;# matches www.kernel.org as well
gitproxy = netcatter for kernel.org
gitproxy = netscatter for sample.xz
gitproxy = none for mydomain.xz
gitproxy = netcatter-default

   The values are command names, followed by an optional " for "
   and domainname; the first tail-match of the domainname
   determines which proxy command is used.  An entry without "
   for " matches any domain and can be used as the default.

   The command name "none" is special -- it tells the mechanism
   not to use any proxy command and use the native git://
   connection.

proxy-command support for git://

I've taken the hostname parsing verbatim from git_tcp_connect(),

that business with the square brackets is.  (Should I move this

Regarding internal vs. external hosts, the proxy command can
simply run netcat locally to internal hosts, so perhaps that is
sufficient.

format-patch: fix two-argument special case, and make it easier to pick single commits

Luben Tuikov noticed that sometimes being able to say
'git-format-patch <commit>' to format the change a single commit
introduces relative to its parent is handy.

This patch does not support that directly, but it makes sense to
interpret a single argument "rev" to mean "rev^1..rev".

With this, the backward compatibility syntaxes still apply:

 - "format-patch master" means "format-patch master..HEAD"
 - "format-patch origin master" means "format-patch origin..master"
 - "format-patch origin.." means "format-patch origin..HEAD"

But "format-patch a b c d e" formats the changes these five
commits introduce relative to their respective parents.  Earlier
it rejected these arguments not in "one..two" form.

Junio C Hamano [Mon, 14 Nov 2005 08:41:53 +0000 (00:41 -0800)]
Rewrite rebase to use git-format-patch piped to git-am.

The current rebase implementation finds commits in our tree but
not in the upstream tree using git-cherry, and tries to apply
them using git-cherry-pick (i.e. always use 3-way) one by one.

Which is fine, but when some of the changes do not apply
cleanly, it punts, and punts badly.

Suppose you have commits A-B-C-D-E since you forked from the
upstream and submitted the changes for inclusion.  You fetch
from upstream head U and find that B has been picked up.  You
run git-rebase to update your branch, which tries to apply
changes contained in A-C-D-E, in this order, but replaying of C
fails, because the upstream got changes that touch the same area
from elsewhere.

Now what?

It notes that fact, and goes ahead to apply D and E, and at the
very end tells you to deal with C by hand.  Even if you somehow
managed to replay C on top of the result, you would now end up
with ...-B-...-U-A-D-E-C.

Breaking the order between B and others was the conscious
decision made by the upstream, so we would not worry about it,
and even if it were worrisome, it is too late for us to fix now.
What D and E do may well depend on having C applied before them,
which is a problem for us.

This rewrites rebase to use git-format-patch piped to git-am,
and when the patch does not apply, have git-am fall back on
3-way merge.  The updated diff/patch pair knows how to apply
trivial binary patches as long as the pre- and post-images are
locally available, so this should work on a repository with
binary files as well.

The primary benefit of this change is that it makes rebase
easier to use when some of the changes do not replay cleanly.
In the "unapplicable patch in the middle" case, this "rebase"
works like this:

 - A series of patches in e-mail form is created that records
   what A-C-D-E do, and is fed to git-am.  This is stored in
   .dotest/ directory, just like the case you tried to apply
   them from your mailbox.  Your branch is rewound to the tip of
   upstream U, and the original head is kept in .git/ORIG_HEAD,
   so you could "git reset --hard ORIG_HEAD" in case the end
   result is really messy.

 - Patch A applies cleanly.  This could either be a clean patch
   application on top of rewound head (i.e. same as upstream
   head), or git-am might have internally fell back on 3-way
   (i.e.  it would have done the same thing as git-cherry-pick).
   In either case, a rebased commit A is made on top of U.

 - Patch C does not apply.  git-am stops here, with conflicts to
   be resolved in the working tree.  Yet-to-be-applied D and E
   are still kept in .dotest/ directory at this point.  What the
   user does is exactly the same as fixing up unapplicable patch
   when running git-am:

   - Resolve conflict just like any merge conflicts.
   - "git am --resolved --3way" to continue applying the patches.

 - This applies the fixed-up patch so by definition it had
   better apply.  "git am" knows the patch after the fixed-up
   one is D and then E; it applies them, and you will get the
   changes from A-C-D-E commits on top of U, in this order.

I've been using this without noticing any problem, and as people
may know I do a lot of rebases.

Make "git fetch" less verbose by default

When doing something like

git fetch --tags origin

the excessively verbose output of git fetch makes the result totally
unreadable. It's impossible to tell if it actually fetched anything new or
not, since the screen will fill up with an endless supply of

   ...
   * committish: 9165ec17fde255a1770886189359897dbb541012
     tag 'v0.99.7c' of master.kernel.org:/pub/scm/git/git
   * refs/tags/v0.99.7c: same as tag 'v0.99.7c' of master.kernel.org:/pub/scm/git/git
   ...

and any new tags that got fetched will be totally hidden.

So add a new "--verbose" flag to "git fetch" to enable this verbose mode,
but make the default be quiet.

NOTE! The quiet mode will still report about new or changed heads, so if
you are really fetching a new head, you'll see something like this:

   [torvalds@g5 git]$ git fetch --tags parent

   * refs/tags/v1.0rc1: storing tag 'v1.0rc1' of master.kernel.org:/pub/scm/git/git

which actually tells you something useful that isn't hidden by all the
useless crud that you already had.

Extensively tested (hey, for me, this _is_ extensive) by doing a

   rm .git/refs/tags/v1.0rc*

and re-fetching with both --verbose and without.

NOTE! This means that if the fetch didn't actually fetch anything at all,
git fetch will be totally quiet. I think that's much better than being so
verbose that you can't even tell whether something was fetched or not, but
some people might prefer to get a "nothing to fetch" message in that case.

Teach "approxidate" about weekday syntax

This allows people to use syntax like "last thursday" for the approxidate.

(Or, indeed, more complex "three thursdays ago", but I suspect that would
be pretty unusual).

NOTE! The parsing is strictly sequential, so if you do

"one day before last thursday"

it will _not_ do what you think it does. It will take the current time,
subtract one day, and then go back to the thursday before that. So to get
what you want, you'd have to write it the other way around:

"last thursday and one day before"

which is insane (it's usually the same as "last wednesday" _except_ if
today is Thursday, in which case "last wednesday" is yesterday, and "last
thursday and one day before" is eight days ago).

Similarly,

"last thursday one month ago"

will first go back to last thursday, and then go back one month from
there, not the other way around.

I doubt anybody would ever use insane dates like that, but I thought I'd
point out that the approxidate parsing is not exactly "standard English".

Side note 2: if you want to avoid spaces (because of quoting issues), you

the number 1, and it totally ignoring superfluous fluff like "ago", so
"last week" ends up being exactly the same thing as "1 week ago". Fine so
far.

It has strange side effects: "last december" will actually parse as "Dec
1", which actually _does_ turn out right, because it will then notice that
it's not December yet, so it will decide that you must be talking about a
date last year. So it actually gets it right, but it's kind of for the
"wrong" reasons.

It also accepts the numbers 1..10 in string format ("one" .. "ten"), so
you can do "ten weeks ago" or "ten hours ago" and it will do the right
thing.

But it will do some really strange thigns too: the string "this will last
forever", will not recognize anyting but "last", which is recognized as
"1", which since it doesn't understand anything else it will think is the
day of the month. So if you do

gitk --since="this will last forever"

the date will actually parse as the first day of the current month.

And it will parse the string "now" as "now", but only because it doesn't
understand it at all, and it makes everything relative to "now".

Similarly, it doesn't actually parse the "ago" or "from now", so "2 weeks
ago" is exactly the same as "2 weeks from now". It's the current date
minus 14 days.

But hey, it's probably better (and certainly faster) than depending on GNU
date. So now you can portably do things like

gitk --since="two weeks and three days ago"
git log --since="July 5"
git-whatchanged --since="10 hours ago"
git log --since="last october"

and it will actually do exactly what you thought it would do (I think). It
will count 17 days backwards, and it will do so even if you don't have GNU
date installed.

(I don't do "last monday" or similar yet, but I can extend it to that too
if people want).

It was kind of fun trying to write code that uses such totally relaxed
"understanding" of dates yet tries to get it right for the trivial cases.
The result should be mixed with a few strange preprocessor tricks, and be
submitted for the IOCCC ;)

Feel free to try it out, and see how many strange dates it gets right. Or
wrong.

And if you find some interesting (and valid - not "interesting" as in
"strange", but "interesting" as in "I'd be interested in actually doing
this) thing it gets wrong - usually by not understanding it and silently
just doing some strange things - please holler.

Now, as usual this certainly hasn't been getting a lot of testing. But my
code always works, no?

of their own. It also saves some time on executing those commands

git --exec-path

heavy-duty loops to call the core programs directly and thus save
the extra fork() / execve() overhead, although that's not really
necessary any more.

where gitweb was found to be using a lot of time and memory to

flag, and if the number of paths that are rename destination
candidates (i.e. new paths with -M, or modified paths with -C)
are larger than that number, skips rename/copy detection even
when -M or -C is specified on the command line.

This commit makes the rename detection limit easier to use.  You
can have:

[diff]
renamelimit = 30

in your .git/config file to specify the default rename detection
limit.  You can override this from the command line; giving 0
means 'unlimited':

git diff -M -l0
