bisect: fix bad rev checking in "git bisect good"
revision.c: make --date-order overriddable
Fix section about backdating tags in the git-tag docs
Document option --only of git commit
Documentation/git-request-pull: Fixed a typo ("send" -> "end")
It seems that "git bisect good" and "git bisect skip" have never
properly checked arguments that have been passed to them. As soon
as one of them can be parsed as a SHA1, no error or warning would
be given.
This is because 'git rev-parse --revs-only --no-flags "$@"' always
"exit 0" and outputs all the SHA1 it can found from parsing "$@".
This patch fix this by using, for each "bisect good" argument, the
same logic as for the "bisect bad" argument.
While at it, this patch teaches "bisect bad" to give a meaningfull
error message when it is passed more than one argument.
Note that if "git bisect good" or "git bisect skip" is given some
proper revs and then something that is not a proper rev, then the
first proper revs will still have been marked as "good" or "skip".

Users are not often aware of the fact that "git bisect -h" can give
them a long usage description, as "git bisect" seems to accept only
dashless subcommands like "start", "good", ...
That's why this patch adds a "git bisect help" subcommand that just
calls "git bisect -h". This new subcommand is also fully documented
in the short usage string (that "git bisect" gives), in the long
usage string and in the man page (that "git help bisect" gives).

This attached patch introduces a single bit "use_terminator" in "struct
rev_info", which is normally false (i.e. most formats use separator
semantics) but by flipping it to true, you can ask for terminator
semantics just like oneline format does.
The function get_commit_format(), which is what parses "--pretty=" option,
now takes a pointer to "struct rev_info" and updates its commit_format and
use_terminator fields. It used to return the value of type "enum
cmit_fmt", but all the callers assigned it to rev->commit_format.
There are only two cases the code turns use_terminator on. Obviously, the
traditional oneline format (--pretty=oneline) is one of them, and the new
case is --pretty=tformat:... that acts like --pretty=format:... but flips
the bit on.
With this, "--pretty=tformat:%H %s" acts like --pretty=oneline.

Many other commands use the "no arguments" form to show a
list (e.g., git-branch, git-tag). While we did show all
remotes for just "git remote", we displayed a usage error
for "git remote show" with no arguments. This is
counterintuitive, since by giving it _more_ information, we
get _less_ result.
The usage model can now be thought of as:
- "git remote show <remote>": show a remote
- "git remote show": show all remotes
- "git remote": assume "show"; i.e., shorthand for "git remote show"

Previously, a fetch like:
git fetch git://some/url
would show no ref status output (just the object downloading
status, if there was any), leading to some confusion.
With this patch, we now show the usual ref table, with
remote refs going into FETCH_HEAD. Previously this output
was shown only if "-v"erbose was specified.

git-fetch: fix status output when not storing tracking ref

git-archive: ignore prefix when checking file attribute
Fix documentation syntax of optional arguments in short options.
There was code in update_local_ref for handling this case,
but it never actually got called. It assumed that storing in
FETCH_HEAD meant a blank peer_ref name, but we actually have
a NULL peer_ref in this case, so we never even made it to
the update_local_ref function.
On top of that, the display formatting was different from
all of the other cases, probably owing to the fact that
nobody had ever actually seen the output.
This patch harmonizes the output with the other cases and
moves the detection of this case into store_updated_refs,
where we can actually trigger it.

Ulrik Sverdrup noticed that git-archive doesn't correctly apply the attribute
export-subst when the option --prefix is given, too.
When it checked if a file has the attribute turned on, git-archive would try
to look up the full path -- including the prefix -- in .gitattributes. That's
wrong, as the prefix doesn't need to have any relation to any existing
directories, tracked or not.
This patch makes git-archive ignore the prefix when looking up if value of the
attribute export-subst for a file.

If we pick 'mi' between 'lo' and 'hi' at 50%, which was what the
simple binary search did, we are halving the search space
whether the entry at 'mi' is lower or higher than the target.
The previous patch was about picking not the middle but closer
to 'hi', when we know the target is a lot closer to 'hi' than it
is to 'lo'. However, if it turns out that the entry at 'mi' is
higher than the target, we would end up reducing the search
space only by the difference between 'mi' and 'hi' (which by
definition is less than 50% --- that was the whole point of not
using the simple binary search), which made the search less
efficient. And the risk of overshooting becomes very high, if
we try to be too precise.
This tweaks the selection of 'mi' to be a bit closer to the
middle than we would otherwise pick to avoid the problem.

the same way as we count similarity for rename detection.

Currently, when looking for a packed object from the pack idx, a
simple binary search is used.
A conventional binary search loop looks like this:
unsigned lo, hi;
do {
unsigned mi = (lo + hi) / 2;
int cmp = "entry pointed at by mi" minus "target";
if (!cmp)
return mi; "mi is the wanted one"
if (cmp > 0)
hi = mi; "mi is larger than target"
else
lo = mi+1; "mi is smaller than target"
} while (lo < hi);
"did not find what we wanted"
The invariants are:
- When entering the loop, 'lo' points at a slot that is never
above the target (it could be at the target), 'hi' points at
a slot that is guaranteed to be above the target (it can
never be at the target).
- We find a point 'mi' between 'lo' and 'hi' ('mi' could be
the same as 'lo', but never can be as high as 'hi'), and
check if 'mi' hits the target. There are three cases:
- if it is a hit, we have found what we are looking for;
- if it is strictly higher than the target, we set it to
'hi', and repeat the search.
- if it is strictly lower than the target, we update 'lo'
to one slot after it, because we allow 'lo' to be at the
target and 'mi' is known to be below the target.
If the loop exits, there is no matching entry.
When choosing 'mi', we do not have to take the "middle" but
anywhere in between 'lo' and 'hi', as long as lo <= mi < hi is
satisfied. When we somehow know that the distance between the
target and 'lo' is much shorter than the target and 'hi', we
could pick 'mi' that is much closer to 'lo' than (hi+lo)/2,
which a conventional binary search would pick.
This patch takes advantage of the fact that the SHA-1 is a good
hash function, and as long as there are enough entries in the
table, we can expect uniform distribution. An entry that begins
with for example "deadbeef..." is much likely to appear much
later than in the midway of a reasonably populated table. In
fact, it can be expected to be near 87% (222/256) from the top
of the table.
This is a work-in-progress and has switches to allow easier
experiments and debugging. Exporting GIT_USE_LOOKUP environment
variable enables this code.
On my admittedly memory starved machine, with a partial KDE
repository (3.0G pack with 95M idx):
$ GIT_USE_LOOKUP=t git log -800 --stat HEAD >/dev/null

There isn't much time difference, but the number of minor faults
seems to show that we are touching much smaller number of pages,
which is expected.

This expands on the previous patch, and allows "git add" to sanely handle
a filename that has changed case, keeping the case in the index constant,
and avoiding aliases.
In particular, if you have an index entry called "File", but the
checked-out tree is case-corrupted and has an entry called "file"
instead, doing a
git add .
(or naming "file" explicitly) will automatically notice that we have an
alias, and will replace the name "file" with the existing index
capitalization (ie "File").
However, if we actually have *both* a file called "File" and one called
"file", and they don't have the same lstat() information (ie we're on a
case-sensitive filesystem but have the "core.ignorecase" flag set), we
will error out if we try to add them both.

This is immaterial on sane filesystems, but if you have a broken (aka
case-insensitive) filesystem, and the objective is to remove the file
'abc' and replace it with the file 'Abc', then we must make sure to do
the removal first.
Otherwise, you'd first update the file 'Abc' - which would just
overwrite the file 'abc' due to the broken case-insensitive filesystem -
and then remove file 'abc' - which would now brokenly remove the just
updated file 'Abc' on that broken filesystem.
By doing removals first, this won't happen.

It's really totally separate functionality, and if we want to start

separated out.
It also renames "remove_index_entry()" to "remove_name_hash()", because
that really describes the thing better. It doesn't actually remove the
index entry, that's done by "remove_index_entry_at()", which is something
very different, despite the similarity in names.
