bisect: refactor sha1_array into a generic sha1 list
This is a generally useful abstraction, so let's let others
make use of it. The refactoring is more or less a straight
copy; however, functions and struct members have had their
names changed to match string_list, which is the most
similar data structure.

refactor refs_from_alternate_cb to allow passing extra data
The foreach_alt_odb function triggers a callback for each
alternate object db we have, with room for a single void
pointer as data. Currently, we always call refs_from_alternate_cb
as the callback function, and then pass another callback (to
receive each ref individually) as the void pointer.
This has two problems:
1. C technically forbids stuffing a function pointer into
a "void *". In practice, this probably doesn't matter
on any architectures git runs on, but it never hurts to
follow the letter of the law.
2. There is no room for an extra data pointer. Indeed, the
alternate_ref_fn that refs_from_alternate_cb calls
takes a void* for data, but we always pass it NULL.
Instead, let's properly stuff our function pointer into a
data struct, which also leaves room for an extra
caller-supplied data pointer. And to keep things simple for
existing callers, let's make a for_each_alternate_ref
function that takes care of creating the extra struct.

Kacper Kornet noticed that a $variable in "word" in the above construct is
not substituted by his pdksh. Modern POSIX compliant shells (e.g. dash,
ksh, bash) all seem to interpret POSIX "2.6.2 Parameter Expansion" that
says "word shall be subjected to tilde expansion, parameter expansion,
command substitution, and arithmetic expansion" in ${parameter<op>word},
to mean that the word is expanded as if it appeared in dq pairs, so if the
word were "'$variable'" (sans dq) it would expand to a single quote, the
value of the $variable and then a single quote.
Johannes Sixt reports that the behavior of quoting at the right of :- when
the ${...:-...} expansion appears in double-quotes was debated recently at
length at the Austin group. We can avoid this issue and future-proof the
test by a slight rewrite.

merge: make branch.<name>.mergeoptions correctly override merge.<option>
The parsing of the additional command line parameters supplied to

at the wrong stage. If any merge-related variable came after we read
branch.<name>.mergeoptions, the earlier value was overwritten.
We should first read all the merge.* configuration, override them by
reading from branch.<name>.mergeoptions and then finally read from
the command line.
This patch should fix it, even though I now strongly suspect that
branch.<name>.mergeoptions that gives a single command line that

Pass empty file to p4merge where no base is suitable.
Modify the p4merge client command to pass a reference to an empty file
instead of the local file when no base revision available.
In the situation where a merge tries to add a file from one branch
into a branch that already contains that file (by name), p4merge
currently seems to have successfully automatically resolved the
'conflict' when it is opened (correctly if the files differed by
just whitespace for example) but leaves the save button disabled. This
means the user of the p4merge client cannot commit the resolved
changes back to disk and merely exits, leaving the original
(merge-conflicted) file intact on the disk.
Provide an empty base file to p4merge so that it leaves the save
button enabled. This will allow saving of the auto-resolution to
disk.

merge-one-file: fix broken merges with alternate work trees
The merge-one-file tool predates the invention of
GIT_WORK_TREE. By the time GIT_WORK_TREE was invented, most
people were using the merge-recursive strategy, which
handles resolving internally. Therefore these features have
had very little testing together.
For the most part, merge-one-file just works with
GIT_WORK_TREE; most of its heavy lifting is done by plumbing
commands which do respect GIT_WORK_TREE properly. The one
exception is a shell redirection which touches the worktree
directly, writing results to the wrong place in the presence
of a GIT_WORK_TREE variable.
This means that merges won't even fail; they will silently
produce incorrect results, throwing out the entire "theirs"
side of files which need content-level merging!
This patch makes merge-one-file chdir to the toplevel of the
working tree (and exit if we don't have one). This most
closely matches the assumption made by the original script
(before separate work trees were invented), and matches what
happens when the script is called as part of a merge
strategy.
While we're at it, we'll also error-check the call to cat.
Merging a file in a subdirectory could in fact fail, as the
redirection relies on the "checkout-index" call just prior
to create leading directories. But we never noticed, since
we ignored the error return from running cat.

There were no tests for either, except a brief use in
t1200-tutorial.
These tools are not used much these days, as most people
use the merge-recursive strategy, which handles everything
internally. However, they are used by the "octopus" and
"resolve" strategies, as well as any custom strategies
or merge scripts people have built around them.
For example, together with read-tree, they are the simplest
way to do a basic content-level merge without checking out
the entire repository contents beforehand.
This script adds a basic test of the tools to perform one
content-level merge. It also shows a failure of the tools to
work properly in the face of GIT_WORK_TREE or core.worktree.

"add -p": work-around an old laziness that does not coalesce hunks
Since 0beee4c (git-add--interactive: remove hunk coalescing, 2008-07-02),
"git add--interactive" behaves lazily and passes overlapping hunks to the
underlying "git apply" without coalescing. This was partially corrected
by 7a26e65 (its partial revert, 2009-05-16), but overlapping hunks are
still passed when the patch is edited.
Teach "git apply" the --allow-overlap option that disables a safety
feature that avoids misapplication of patches by not applying patches
to overlapping hunks, and pass this option form "add -p" codepath.
Do not even advertise the option, as this is merely a workaround, and the
correct fix is to make "add -p" correctly coalesce adjacent patch hunks.
add--interactive.perl: factor out repeated --recount option
Depending on the direction and the target of patch application, we would
need to pass --cached and --reverse to underlying "git apply". Also we
only pass --check when we are not applying but just checking.
But we always pass --recount since 8cbd431 (git-add--interactive: replace
hunk recounting with apply --recount, 2008-07-02). Instead of repeating
the same --recount over and over again, move it to a single place that
actually runs the command, namely, "run_git_apply" subroutine.
t3701: Editing a split hunk in an "add -p" session
Arnaud Lacombe reported that with the recent change to reject overlapping
hunks fed to "git apply", the edit mode of an "add -p" session that lazily
feeds overlapping hunks without coalescing adjacent ones claim that the
patch does not apply. Expose the problem to be fixed.
The "quit" command was added in 9a7a1e0 (git add -p: new "quit" command at
the prompt, 2009-04-10) to allow the user to say that hunks other than
what have already been chosen are undesirable, and exit the interactive
loop immediately. It forgot that there may be an undecided hunk before
the current one. In such a case, the interactive loop still goes back to
the beginning.
Clear all the USE bit for undecided hunks and exit the loop.
git-send-email: fix missing space in error message
When the command cannot make a connection to the SMTP server the error
message to diagnose the broken configuration is issued. However, when an

blame: tolerate bogus e-mail addresses a bit better

When parsing the email part out, the current code looks for SP starting
from the end of the email part, but the author could obfuscate the address
as "author at example dot com".
We should instead look for SP followed by "<", to match the logic of the

git-rebase--interactive.sh: preserve-merges fails on merges created with no-ff
'git rebase' uses 'git merge' to preserve merges (-p). This preserves
the original merge commit correctly, except when the original merge
commit was created by 'git merge --no-ff'. In this case, 'git rebase'
will fail to preserve the merge, because during 'git rebase', 'git
merge' will simply fast-forward and skip the commit. For example:
B
/ \
A---M
/
---o---O---P---Q
If we try to rebase M onto P, we lose the merge commit and this happens:
A---B
/
---o---O---P---Q
To correct this, we simply do a "no fast-forward" on all merge commits
when rebasing. Since by the time we decided to do a 'git merge' inside
'git rebase', it means there was a merge originally, so 'git merge'
should always create a merge commit regardless of what the merge
branches look like. This way, when rebase M onto P from the above
example, we get:
B
/ \
A---M
/
---o---O---P---Q

If somebody has a name that includes an rfc822 special, we
will output it literally in the "From:" header. This is
usually OK, but certain characters (like ".") are supposed
to be enclosed in double-quotes in a mail header.
In practice, whether this matters may depend on your MUA.
Some MUAs will happily take in:
From: Foo B. Bar <author@example.com>
without quotes, and properly quote the "." when they send
the actual mail. Others may not, or may screw up harder
things like:
From: Foo "The Baz" Bar <author@example.com>
For example, mutt will strip the quotes, thinking they are
actual syntactic rfc822 quotes.
So let's quote properly, and then (if necessary) we still
apply rfc2047 encoding on top of that, which should make all
MUAs happy.

Fix "add -u" that sometimes fails to resolve unmerged paths
"git add -u" updates the index with the updated contents from the working
tree by internally running "diff-files" to grab the set of paths that are
different from the index. Then it updates the index entries for the paths
that are modified in the working tree, and deletes the index entries for
the paths that are deleted in the working tree.
It ignored the output from the diff-files that indicated that a path is
unmerged. For these paths, it instead relied on the fact that an unmerged
path is followed by the result of comparison between stage #2 (ours) and
the working tree, and used that to update or delete such a path when it is
used to record the resolution of a conflict.
As the result, when a path did not have stage #2 (e.g. "we deleted while
the other side added"), these unmerged stages were left behind, instead of
recording what the user resolved in the working tree.
Since we recently fixed "diff-files" to indicate if the corresponding path
exists on the working tree for an unmerged path, we do not have to rely on
the comparison with stage #2 anymore. We can instead tell the diff-files
not to compare with higher stages, and use the unmerged output to update
the index to reflect the state of the working tree.
The changes to the test vector in t2200 illustrates the nature of the bug
and the fix. The test expected stage #1 and #3 entries be left behind,
but it was codifying the buggy behaviour.
Earlier, e9c8409 (diff-index --cached --raw: show tree entry on the LHS
for unmerged entries., 2007-01-05) taught the command to show the object
name and the mode from the entry coming from the tree side when comparing
a tree with an unmerged index.
This is a belated companion patch that teaches diff-files to show the mode
from the entry coming from the working tree side, when comparing an
unmerged index and the working tree.
diff: remove often unused parameters from diff_unmerge()
e9c8409 (diff-index --cached --raw: show tree entry on the LHS for
unmerged entries., 2007-01-05) added a <mode, object name> pair as
parameters to this function, to store them in the pre-image side of an
unmerged file pair. Now the function is fixed to return the filepair it
queued, we can make the caller on the special case codepath to do so.
The underlying diff_queue() returns diff_filepair so that the caller can
further add information to it, and the helper function diff_unmerge()
utilizes the feature itself, but does not expose it to its callers, which
was kind of selfish.
date: avoid "X years, 12 months" in relative dates
When relative dates are more than about a year ago, we start
writing them as "Y years, M months". At the point where we
calculate Y and M, we have the time delta specified as a
number of days. We calculate these integers as:
Y = days / 365
M = (days % 365 + 15) / 30
This rounds days in the latter half of a month up to the
nearest month, so that day 16 is "1 month" (or day 381 is "1
year, 1 month").
We don't round the year at all, though, meaning we can end
up with "1 year, 12 months", which is silly; it should just
be "2 years".
Documentation: describe the format of messages with inline patches
Add a DISCUSSION section to the "git format-patch" manual to encourage
people to send patches in a form that can be applied by "git am"
automatically. There are two such forms:
1. The default form in which most metadata goes in the mail header
and the message body starts with the patch description;
2. The snipsnip form in which a message starts with pertinent
discussion and ends with a patch after a "scissors" mark.
The example requires QP encoding in the "Subject:" header intended for
the mailer to give the reader a chance to reflect on that, rather than
being startled by it later. By contrast, in-body "From:" and
"Subject:" lines should be human-readable and not QP encoded.
