The type 'off_t' should be used everywhere so that the bit-depth of that
type can be adjusted in the standard C library, and you just need to
recompile your program to benefit from the extended precision.
Only that it was not done that way in the MS runtime library.
This patch reroutes off_t to off64_t and provides the other necessary
changes so that finally, clones larger than 2 gigabyte work on Windows
(provided you are on a file system that allows files larger than 2gb).

would say "unable to chdir or not a git archive". The

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.
N : linear case --> probabilities --> best
-------------------------------------------------------------
1 : G-B --> 0 --> 0
2 : G-U1-B --> 0 --> 0
3 : G-U1-U2-B --> 0(1/3) 1(2/3) --> 1
4 : G-U1-U2-U3-B --> 1 --> 1
5 : G-U1-U2-U3-U4-B --> 1(3/5) 2(2/5) --> 1
6 : G-U1-U2-U3-U4-U5-B --> 1(2/6) 2(4/6) --> 2
7 : G-U1-U2-U3-U4-U5-U6-B --> 1(1/7) 2(6/7) --> 2
8 : G-U1-U2-U3-U4-U5-U6-U7-B --> 2 --> 2
9 : G-U1-U2-U3-U4-U5-U6-U7-U8-B --> 2(7/9) 3(2/9) --> 2
10: G-U1-U2-U3-U4-U5-U6-U7-U8-U9-B --> 2(6/10)3(4/10)--> 2
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 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

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.

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 --unpacked=<packfile> parameter from the revision parser, and
rewrites its use in git-repack to pass a single --kept-pack-only option

This refactors three loops that check if a given packfile is on the

not have corresponding .keep files, i.e. a packfile not on the list is
"kept".
