connect.c: remove a few globals by using git_config callback data
Since ef90d6d (Provide git_config with a callback-data parameter,
2008-05-14), git_config() takes a callback data pointer that can be
used to pass extra parameters to the parsing function. The codepath
to parse configuration variables related to git proxy predates this
facility and used a pair of file scope static variables instead.
This patch removes the need for these global variables by passing the
name of the host we are trying to access as the callback data.

parseopt: prevent KEEP_UNKNOWN and STOP_AT_NON_OPTION from being used together
As suggested by Junio, disallow the flags PARSE_OPT_KEEP_UNKNOWN and
PARSE_OPT_STOP_AT_NON_OPTION to be turned on at the same time, as a
value of an unknown option could be mistakenly classified as a
non-option, stopping the parser early. E.g.:
git cmd --known --unknown value arg0 arg1
The parser should have stopped at "arg0", but it already stops at
"value".
This patch makes parse_options() die if the two flags are used in
combination.

Replace the hand-rolled parsers that find and remove --remote and --exec
by a parseopt parser that also handles --output.
All three options only have a meaning if no remote server is used or on
the local side. They must be rejected by upload-archive and should not
be sent to the server by archive.
We can't use a single parser for both remote and local side because the
remote end possibly understands a different set of options than the
local side. A local parser would then wrongly accuse options valid on
the other side as being incorrect.
This patch implements a very forgiving parser that understands only the
three options mentioned above. All others are passed to the normal,
complete parser in archive.c (running either locally in archive, or
remotely in upload-archive). This normal parser definition contains
dummy entries for the three options, in order for them to appear in the
help screen.
The parseopt parser allows multiple occurrences of --remote and --exec
unlike the previous one; the one specified last wins. This looseness
is acceptable, I think.

Add an (optional, since expensive) test for >2gb clones
Define GIT_TEST_CLONE_2GB=t if you want the test not to be skipped.
The test works by constructing a repository larger than 2gb, and then
cloning it.
The repository is forced larger than 2gb by setting compression and
delta depth to zero, and then adding just enough unique objects of
a given size.
The objects consist of a running decimal number in ASCII, padded by
spaces. Should that break in the future, e.g. when pack v4 becomes
default, there is a commented-out call to test-genrandom which can be
substituted, but that uses more cycles than the current method.

bash completion: fix completion issues with fetch, pull, and push
Sverre Rabbelier noticed a completion issue with push:
$ git push ori<tab>
git push origin
$ git push -f ori<tab>
git push -f origin/
Markus Heidelberg pointed out that the issue extends to fetch and pull.
The reason is that the current code naively assumes that if
COMP_CWORD=2, it should complete a remote name, otherwise it should
complete a refspec. This assumption fails if there are any --options.
This patch fixes that issue by instead scanning COMP_CWORDS to see if
the remote has been completed yet (we now assume the first non-dashed
argument is the remote). The new logic is factored into a function,
shared by fetch, pull, and push.
The new function also properly handles '.' as the remote.

This patch teaches "git rev-list --bisect-vars" to output an estimate
of the number of bisection step left _after the current one_ along with
the other variables it already outputs.
This patch also makes "git-bisect.sh" display this number of steps left
_after the current one_, along with the estimate of the number of
revisions left to test (after the current one).
Here is a table to help analyse what should be the best estimate for
the number of bisect steps left.
In the column "N", there is the number of revisions that could _now_
be the first bad commit we are looking for.
The "linear case" column describes the linear history corresponding to
the number in column N. G means good, B means bad, and Ux means
unknown. Note that the first bad revision we are looking for can be
any Ux or B.
In the "probabilities" column, there are the different outcomes in
number of steps with the odds of each outcome in parenthesis
corresponding to the linear case.
The "best" column gives the most accurate estimate among the different
outcomes in the "probabilities" column.
We have the following:
best(2^n) == n - 1
and for any x between 0 included and 2^n excluded, the probability for
n - 1 steps left looks like:
P(2^n + x) == (2^n - x) / (2^n + x)
and P(2^n + x) < 0.5 means 2^n < 3x
So the algorithm used in this patch calculates 2^n and x, and then
choose between returning n - 1 and n.

send-email: add --confirm option and configuration setting
send-email violates the principle of least surprise by automatically
cc'ing additional recipients without confirming this with the user.
This patch teaches send-email a --confirm option. It takes the
following values:
--confirm=always always confirm before sending
--confirm=never never confirm before sending
--confirm=cc confirm before sending when send-email has
automatically added addresses from the patch to
the Cc list
--confirm=compose confirm before sending the first message when
using --compose. (Needed to maintain backwards
compatibility with existing behavior.)
--confirm=auto 'cc' + 'compose'
If sendemail.confirm is unconfigured, the option defaults to 'compose'
if any suppress-Cc related options have been used, otherwise it defaults
to 'auto'.
Unfortunately, it is impossible to introduce this patch such that it
helps new users without potentially annoying some existing users. We
attempt to mitigate the latter by:
* Allowing the user to set 'git config sendemail.confirm never'
* Allowing the user to say 'all' after the first prompt to not be
prompted on remaining emails during the same invocation.
* Telling the user about the 'sendemail.confirm' setting if it is
unconfigured whenever we prompt due to Cc before sending.
* Only prompting if no --suppress related options have been passed, as
using such an option is likely to indicate an experienced send-email
user.
There is a slight fib in message informing the user of the
sendemail.confirm setting and this is intentional. Setting 'auto'
differs from leaving sendemail.confirm unset in two ways: 1) 'auto'
obviously squelches the informational message; 2) 'auto' prompts when
the Cc list has been expanded even in the presence of a --suppress
related option, where leaving sendemail.confirm unset does not. This is
intentional to keep the message simple, and to avoid adding another
sendemail.confirm value ('auto-except-suppress'?).

When memmem() was imported from glibc 2.2 into compat/, an optimization
was dropped in the process, in order to make the code smaller and simpler.
It was OK because memmem() wasn't used in performance-critical code. Now
the situation has changed and we can benefit from this optimization.
The trick is to avoid calling memcmp() if the first character of the needle
already doesn't match. Checking one character directly is much cheaper
than the function call overhead. We keep the first character of the needle
in the variable named point and the rest in the one named tail.

Use memmem() instead of open-coding it. The system libraries usually have a
much faster version than the memcmp()-loop here. Even our own fall-back in
compat/, which is used on Windows, is slightly faster.

Short story: There is a section in t3400 that tests fundamental rebase
properties. 3ec7371f (Add two extra tests for git rebase, 2009-02-09)
added a check that rebase works on a detached HEAD, but the test was put
near the end of the file. This moves it to a more suitable place.
Long story: The test that preceded the one in question tests that a
rebased commit degrades from a content change with mode change to a
mere mode change. But on Windows, where we have core.filemode=false,
the original commit did not record the mode change, and so the rebase
operation did not rebase anything. This caused the subsequent detached
HEAD test to fail.

There were actually two problems. This recipe created a situation where
git log would output a child commit after its parent. This meant that
we called fix_reversal which called splitvarc, which should call modify_arc
to note the fact that it has modified the arc that it has just split. It
wasn't, which meant that displayorder and other variables got into an
inconsistent state (a commit appearing twice in displayorder).
This then meant that the targetrow/targetid logic in drawvisible thought
it need to redraw each time. That, together with the fact that drawvisible
called drawcommits which called drawvisible if a redraw was needed, led
to the infinite loop.
In fact drawvisible is now the only caller of drawcommits. Thus, the
start and end row arguments to drawcommits always encompass the whole
visible area, so drawcommits doesn't need to call drawvisible to redraw;
it just needs to clear the screen and draw what it's been asked to.
This fixes these two problems by adding a call to modify_arc in
splitvarc and by taking out the call to drawvisible in drawcommits.
It also removes an unrelated left-over debugging puts in external_blame.
The parameters accepted by the --whitespace option of "git apply" have
changed over time, and the documentation for "git rebase" was out of
sync. Remove the specific parameter list from the "git rebase"
documentation and simply point to the "git apply" documentation for
details, as is already done in the "git am" documentation.

Now is_kept_pack() is just a member lookup into a structure, we can write
it as such.
Also rewrite the sole caller of has_sha1_kept_pack() to switch on the
criteria the callee uses (namely, revs->kept_pack_only) between calling
has_sha1_kept_pack() and has_sha1_pack(), so that these two callees do not
have to take a pointer to struct rev_info as an argument.
This removes the header file dependency issue temporarily introduced by
the earlier commit, so we revert changes associated to that as well.
This removes --unpacked=<packfile> parameter from the revision parser, and
rewrites its use in git-repack to pass a single --kept-pack-only option
instead.
The new --kept-pack-only option means just that. When this option is
given, is_kept_pack() that used to say "not on the --unpacked=<packfile>
list" now says "the packfile has corresponding .keep file".
This refactors three loops that check if a given packfile is on the
ignore_packed list into a function is_kept_pack(). The function returns
false for a pack on the list, and true for a pack not on the list, because
this list is solely used by "git repack" to pass list of packfiles that do
not have corresponding .keep files, i.e. a packfile not on the list is
"kept".
Its "ignore_packed" parameter always comes from struct rev_info. This
patch makes the function take a pointer to the surrounding structure, so
that the refactoring in the next patch becomes easier to review.
There is an unfortunate header file dependency and the easiest workaround
is to temporarily move the function declaration from cache.h to
revision.h; this will be moved back to cache.h once the function loses
this "ignore_packed" parameter altogether in the later part of the
series.
has_sha1_pack(): refactor "pretend these packs do not exist" interface
Most of the callers of this function except only one pass NULL to its last
parameter, ignore_packed.
Introduce has_sha1_kept_pack() function that has the function signature
and the semantics of this function, and convert the sole caller that does
not pass NULL to call this new function.
All other callers and has_sha1_pack() lose the ignore_packed parameter.
