robust to additions and deletions of properties.

Refactor struct transport_ops inlined into struct transport
Aside from reducing the code by 20 lines this refactoring removes
a level of indirection when trying to access the operations of a
given transport "instance", making the code clearer and easier to
follow.
It also has the nice effect of giving us the benefits of C99 style
struct initialization (namely ".fetch = X") without requiring that
level of language support from our compiler. We don't need to worry
about new operation methods being added as they will now be NULL'd
out automatically by the xcalloc() we use to create the new struct
transport we supply to the caller.
This pattern already exists in struct walker, so we already have
a precedent for it in Git. We also don't really need to worry
about any sort of performance decreases that may occur as a result
of filling out 4-8 op pointers when we make a "struct transport".
The extra few CPU cycles this requires over filling in the "struct
transport_ops" is killed by the time it will take Git to actually
*use* one of those functions, as most transport operations are
going over the wire or will be copying object data locally between
two directories.

Avoid printing unnecessary warnings during fetch and push

output itself. Instead we should let the higher level application
do the output if it is necessary. This avoids always telling the
user that depth isn't supported on HTTP urls even when they did
not pass a --depth option to git-fetch.
If the user passes an option and the option value is invalid we now
properly die in git-fetch instead of just spitting out a message

incorrect/malformed options are not accepted by the process.

Correct handling of branch.$name.merge in builtin-fetch
My prior bug fix for git-push titled "Don't configure remote "." to
fetch everything to itself" actually broke t5520 as we were unable
to evaluate a branch configuration of:
as remote "." did not have a "remote...fetch" configuration entry to
offer up refs/heads/master as a possible candidate available to be
fetched and merged. In shell script git-fetch and prior to the above
mentioned commit this was hardcoded for a url of "." to be the set of
local branches.
Chasing down this bug led me to the conclusion that our prior behavior
with regards to branch.$name.merge was incorrect. In the shell script
based git-fetch implementation we only fetched and merged a branch if
it appeared both in branch.$name.merge *and* in remote.$r.fetch, where
$r = branch.$name.remote. In other words in the following config file:
Attempting to run `git pull` while on branch "pu" would always give
the user "Already up-to-date" as git-fetch did not fetch pu and thus
did not mark it for merge in .git/FETCH_HEAD. The configured merge
would always be ignored and the user would be left scratching her
confused head wondering why merge did not work on "pu" but worked
fine on "master".
If we are using the "default fetch" specification for the current
branch and the current branch has a branch.$name.merge configured
we now union it with the list of refs in remote.$r.fetch. This
way the above configuration does what the user expects it to do,
which is to fetch only "master" by default but when on "pu" to
fetch both "master" and "pu".
This uncovered some breakage in the test suite where old-style Cogito
branches (.git/branches/$r) did not fetch the branches listed in
.git/config for merging and thus did not actually merge them if the
user tried to use `git pull` on that branch. Junio and I discussed
it on list and felt that the union approach here makes more sense to
DWIM for the end-user than silently ignoring their configured request
so the test vectors for t5515 have been updated to include for-merge
lines in .git/FETCH_HEAD where they have been configured for-merge
in .git/config.
Since we are now performing a union of the fetch specification and
the merge specification and we cannot allow a branch to be listed
twice (otherwise it comes out twice in .git/FETCH_HEAD) we need to
perform a double loop here over all of the branch.$name.merge lines
and try to set their merge flag if we have already schedule that
branch for fetching by remote.$r.fetch. If no match is found then
we must add new specifications to fetch the branch but not store it
as no local tracking branch has been designated.

Don't attempt to merge non-existant remotes in t5515
This was actually reverted in 756373da by Junio. We no longer
support merging the right hand side of a fetchspec in a branch's
branch.$name.merge configuration setting as we interpret these
names as being only those published by the remote we are going to
fetch from.
The older shell based implementation of git-fetch did not report an
error when branch.$name.merge was referencing a branch that does
not exist on the remote and we are running `git fetch` for the
current branch. The new builtin-fetch does notice this failure
and aborts the fetch, thus breaking the tests.
Junio and I kicked it around on #git earlier today and decided that
the best approach here is to error out and tell the user that their
configuration is wrong, as this is likely more user friendly than
silently ignoring the user's request. Since the new builtin-fetch
is already issuing the error there is no code change required, we
just need to remove the bad configuration from our test.

Don't configure remote "." to fetch everything to itself
When we are talking about a remote URI of "." we are really talking
about *this* repository that we are fetching into or pushing out of.
There are no matching tracking branches for this repository; we
do not attempt to map a ref back to ourselves as this would either
create an infinite cycle (for example "fetch = +refs/*:refs/mine/*")
or it causes problems when we attempt to push back to ourselves.
So we really cannot setup a remote like this:
[remote "."]
url = .
fetch = +refs/*:refs/*
In the case of `git push . B:T` to fast-forward branch T to B's
current commit git-send-pack will update branch T to B, assuming that
T is the remote tracking branch for B. This update is performed
immediately before git-send-pack asks git-receive-pack to perform
the same update, and git-receive-pack then fails because T is not
where git-send-pack told it to expect T to be at.
In the case of `git fetch .` we really should do the same thing as
`git fetch $otherrepo`, that is load .git/FETCH_HEAD with the commit
of HEAD, so that `git pull .` will report "Already up-to-date".
We have always behaved like this before on this insane request and
we should at least continue to behave the same way. With the above
(bad) remote configuration we were instead getting fetch errors
about funny refs, e.g. "refs/stash".

Properly cleanup in http_cleanup so builtin-fetch does not segfault

immediately on http/https/ftp style URLs (those that went through
libcurl and the commit walker). Although the builtin-fetch changes
in this area were really just minor refactorings there was one major
change made: we invoked http_init(), http_cleanup() then http_init()
again in the same process.
When we call curl_easy_cleanup() on each active_request_slot we
are telling libcurl we did not want that buffer to be used again.
Unfortunately we did not also deallocate the active_request_slot
itself nor did we NULL out active_queue_head. This lead us to
attempt to reuse these cleaned up libcurl handles when we later tried
to invoke http_init() a second time to reactivate the curl library.
The next file get operation then immediately segfaulted on most
versions of libcurl.
Properly freeing our own buffers and clearing the list causes us to
reinitialize the curl buffers again if/when we need to use libcurl
from within this same process.

Fix builtin-fetch memory corruption by not overstepping array
A long time ago Junio added this line to always ensure that the
output array created by remove_duplicates() had a NULL as its
terminating node. Today none of the downstream consumers of this
array care about a NULL terminator; they only pay attention to the
size of the array (as indicated by nr_heads). In (nearly?) all
cases passing a NULL element will cause SIGSEGV failures. So this
NULL terminal is not actually necessary.
Unfortunately we cannot continue to NULL terminate the array at
this point as the array may only have been allocated large enough
to match the input of nr_heads. If there are no duplicates than
we would be trying to store NULL into heads[nr_heads] and that may
be outside of the array.
My recent series to cleanup builtin-fetch changed the allocation of
the heads array from 256 entries to exactly nr_heads thus ensuring
we were always overstepping the array and causing memory corruption.

Refactor index-pack "keep $sha1" handling for reuse
There is a subtle (but important) linkage between receive-pack and
index-pack that allows index-pack to create a packfile but protect
it from being deleted by a concurrent `git repack -a -d` operation.
The linkage works by having index-pack mark the newly created pack
with a ".keep" file and then it passes the SHA-1 name of that new
packfile to receive-pack along its stdout channel.
The receive-pack process must unkeep the packfile by deleting the
.keep file, but can it can only do so after all elgible refs have
been updated in the receiving repository. This ensures that the
packfile is either kept or its objects are reachable, preventing
a concurrent repacker from deleting the packfile before it can
determine that its objects are actually needed by the repository.
The new builtin-fetch code needs to perform the same actions if
it choose to run index-pack rather than unpack-objects, so I am
moving this code out to its own function where both receive-pack
and fetch-pack are able to invoke it when necessary. The caller
is responsible for deleting the returned ".keep" and freeing the
path if the returned path is not NULL.

more robust and efficient. More importantly, it should
serve as a quick template for interfacing fast-import with
perl scripts.

This example just puts a directory under git control. It is
significantly slower than using the git tools directly, but
hopefully shows a bit how fast-import works.

git-commit: partial commit of paths only removed from the index
Because a partial commit is meant to be a way to ignore what are
staged in the index, "git rm --cached A && git commit A" should
just record what is in A on the filesystem. The previous patch
made the command sequence to barf, saying that A has not been
added yet. This fixes it.

git-commit: Allow partial commit of file removal.
When making a partial commit, git-commit uses git-ls-files with
the --error-unmatch option to expand and sanity check the user
supplied path patterns. When any path pattern does not match
with the paths known to the index, it errors out, in order to
catch a common mistake to say "git commit Makefiel cache.h"
and end up with a commit that touches only cache.h (notice the
misspelled "Makefile"). This detection however does not work
well when the path has already been removed from the index.
If you drop a path from the index and try to commit that
partially, i.e.
the command complains because git does not know anything about
COPYING anymore.
This introduces a new option --with-tree to git-ls-files and
uses it in git-commit when we build a temporary index to
write a tree object for the partial commit.
When --with-tree=<tree-ish> option is specified, names from the
given tree are added to the set of names the index knows about,
so we can treat COPYING file in the example as known.
Of course, there is no reason to use "git rm" and git-aware
people have long time done:

send-email: make message-id generation a bit more robust
Earlier code took Unix time and appended a few random digits.
If you are firing off many messages within a second, you could
issue the same id to different messages, which is a no-no. If
you send out 31 messages within a single second, with random
integer taken out of rand(4200), you have about 10% chance of
producing the same message ID.
This fixes the problem by uses a prefix string which is
constant-per-invocation (time and pid), with a serial number for
each message generated by the process appended at the end.

git-gui: Disable native platform text selection in "lists"
Sometimes we use a Tk text widget as though it were a listbox.
This happens typically when we want to show an icon to the left
of the text label or just when a text widget is generally a better
choice then the native listbox widget.
In these cases if we want the user to have control over the selection
we implement our own "in_sel" tag that shows the selected region
and we perform our own selection management in the background
via keybindings and mouse bindings. In such uses we don't want
the user to be able to activate the native platform selection by
dragging their mouse through the text widget. Doing so creates a
very confusing display and the user is left wondering what it may
mean to have two different types of selection in the same widget.
Tk doesn't allow us to delete the "sel" tag that it uses internally
to manage the native selection but it will allow us to make it
invisible by setting the tag to have the same display properties
as unselected text. So long as we don't actually use the "sel"
tag for anything in code its effectively invisible.

documentation: replace Discussion section by link to user-manual chapter
The "Discussion" section has a lot of useful information, but is a
little wordy, especially for an already-long man page, and is designed
for an audience more of potential git hackers than users, which probably
doesn't make as much sense as git matures. Also, I (perhaps foolishly)
forked a version in the user manual, which has been significantly
rewritten in an attempt to address some of the above problems.
So, remove this section and replace it by a (very terse) summary of the
original material--my attempt at the World's Shortest Git Overview--and
a reference to the appropriate chapter of the user manual. It's
unfortunate to remove something that's been in this place for a long
time, as some people may still depend on finding it there. But I think
we'll want to do this some day anyway.

I cribbed most of this chapter from the README (now core-intro.txt and

too lazy to rewrite it. The audience isn't quite right, though--the
chapter is a mixture of user- and developer- level documentation that

revision walker: --cherry-pick is a limited operation
We used to rely on the fact that cherry-pick would trigger the code path
to set limited = 1 in handle_commit(), when an uninteresting commit was
encountered.
However, when cherry picking between two independent branches, i.e. when
there are no merge bases, and there is only linear development (which can
happen when you cvsimport a fork of a project), no uninteresting commit
will be encountered.
So set limited = 1 when --cherry-pick was asked for.
