As v1.7.8-rc0~141^2~4 (2011-08-04) explains, git cherry-pick removes
the sequencer state just before applying the final patch. In the
single-pick case, that was a good thing, since --abort and --continue
work fine without access to such state and removing it provides a
signal that git should not complain about the need to clobber it ("a
cherry-pick or revert is already in progress") in sequences like the
following:
git cherry-pick foo
git read-tree -m -u HEAD; # forget that; let's try a different one
git cherry-pick bar
After the recent patch "allow single-pick in the middle of cherry-pick
sequence" we don't need that hack any more. In the new regime, a
traditional "git cherry-pick <commit>" command never looks at
.git/sequencer, so we do not need to cripple "git cherry-pick
<commit>..<commit>" for it any more.
So now you can run "git cherry-pick --abort" near the end of a
multi-pick sequence and it will abort the entire sequence, instead of
misbehaving and aborting just the final commit.

After messing up a difficult conflict resolution in the middle of a
cherry-pick sequence, it can be useful to be able to
git checkout HEAD . && git cherry-pick that-one-commit
to restart the conflict resolution. The current code however errors out
saying that another cherry-pick is already in progress.

Since 7e2bfd3f (revert: allow cherry-picking more than one commit,
2010-07-02), the pick/revert machinery has kept track of the set of
commits to be cherry-picked or reverted using commit_argc and
commit_argv variables, storing the corresponding command-line
parameters.
Future callers as other commands are built in (am, rebase, sequencer)
may find it easier to pass rev-list options to this machinery in
already-parsed form. Teach cmd_cherry_pick and cmd_revert to parse
the rev-list arguments in advance and pass the commit set to
pick_revisions() as a rev_info structure.

When "git cherry-pick ..bar" encounters conflicts, permit the operator
to use cherry-pick --continue after resolving them as a shortcut for
"git commit && git cherry-pick --continue" to record the resolution
and carry on with the rest of the sequence.
This improves the analogy with "git rebase" (in olden days --continue
was the way to preserve authorship when a rebase encountered
conflicts) and fits well with a general UI goal of making "git cmd
--continue" save humans the trouble of deciding what to do next.
Example: after encountering a conflict from running "git cherry-pick
foo bar baz":
CONFLICT (content): Merge conflict in main.c
error: could not apply f78a8d98c... bar!
hint: after resolving the conflicts, mark the corrected paths
hint: with 'git add <paths>' or 'git rm <paths>'
hint: and commit the result with 'git commit'
We edit main.c to resolve the conflict, mark it acceptable with "git
add main.c", and can run "cherry-pick --continue" to resume the
sequence.
$ git cherry-pick --continue
[editor opens to confirm commit message]
[master 78c8a8c98] bar!
1 files changed, 1 insertions(+), 1 deletions(-)
[master 87ca8798c] baz!
1 files changed, 1 insertions(+), 1 deletions(-)
This is done for both codepaths to pick multiple commits and a single
commit.

The "git cherry-pick --abort" command currently renames the
.git/sequencer directory to .git/sequencer-old instead of removing it
on success due to an accident. cherry-pick --abort is designed to
work in three steps:
1) find which commit to roll back to
2) call "git reset --merge <commit>" to move to that commit
3) remove the .git/sequencer directory
But the careless author forgot step 3 entirely. The only reason the
command worked anyway is that "git reset --merge <commit>" renames the
.git/sequencer directory as a secondary effect --- after moving to
<commit>, or so the logic goes, it is unlikely but possible that the
caller of git reset wants to continue the series of cherry-picks that
was in progress, so git renames the sequencer state to
.git/sequencer-old to be helpful while allowing the cherry-pick to be
resumed if the caller did not want to end the sequence after all.
By running "git cherry-pick --abort", the operator has clearly
indicated that she is not planning to continue cherry-picking. Remove
the (renamed) .git/sequencer directory as intended all along.

After running some ill-advised command like "git cherry-pick
HEAD..linux-next", the bewildered novice may want to return to more
familiar territory. Introduce a "git cherry-pick --abort" command
that rolls back the entire cherry-pick sequence and places the
repository back on solid ground.
Just like "git merge --abort", this internally uses "git reset
--merge", so local changes not involved in the conflict resolution are
preserved.

When conflicts are encountered while reverting a commit, it can be
handy to have the name of that commit easily available. For example,
to produce a copy of the patch to refer to while resolving conflicts:
$ git revert 2eceb2a8
error: could not revert 2eceb2a8... awesome, buggy feature
$ git show -R REVERT_HEAD >the-patch
$ edit $(git diff --name-only)
Set a REVERT_HEAD pseudoref when "git revert" does not make a commit,
for cases like this. This also makes it possible for scripts to
distinguish between a revert that encountered conflicts and other
sources of an unmerged index.
After successfully committing, resetting with "git reset", or moving
to another commit with "git checkout" or "git reset", the pseudoref is
no longer useful, so remove it.

The option to "git cherry-pick" and "git revert" to discard the
sequencer state introduced by v1.7.8-rc0~141^2~6 (revert: Introduce
--reset to remove sequencer state, 2011-08-04) has a confusing name.
Change it now, while we still have the time.
The new name for "cherry-pick, please get out of my way, since I've
long forgotten about the sequence of commits I was cherry-picking when
you wrote that old .git/sequencer directory" is --quit. Mnemonic:
this is analagous to quiting a program the user is no longer using ---
we just want to get out of the multiple-command cherry-pick procedure
and not to reset HEAD or rewind any other old state.
The "--reset" option is kept as a synonym to minimize the impact. We
might consider dropping it for simplicity in a separate patch, though.
Adjust documentation and tests to use the newly preferred name (--quit)
instead of --reset. While at it, let's clarify the short descriptions
of these operations in "-h" output.
Before:
--reset forget the current operation
--continue continue the current operation
After:
--quit end revert or cherry-pick sequence
--continue resume revert or cherry-pick sequence

In particular, the url passed to git-clone has an extra '/' given
after the 'file://' schema prefix, thus:
git clone --reference=original "file:///$(pwd)/original one
Once the prefix is removed, the remainder of the url looks something
like "//home/ramsay/git/t/...", which is then interpreted as an
network path. This then results in a "Permission denied" error, like
so:
ramsay $ ls //home
ls: cannot access //home: No such host or network path
ramsay $ ls //home/ramsay
ls: cannot access //home/ramsay: Permission denied
ramsay $
In order to fix the problem, we simply remove the extraneous '/'
character from the url.

The add_extra_ref() interface is used to add an extra-ref that is _not_
our ref for the purpose of helping auto-following of tags and reducing
object transfer from remote repository, and they are typically formatted
as a tagname followed by ^{} to make sure no valid refs match that
pattern. In other words, these entries are deliberately formatted not to
pass check-refname-format test.
A recent series however added a test unconditionally to the add_ref()
function that is called from add_extra_ref(). The check may be sensible
for other two callsites of the add_ref() interface, but definitely is
a wrong thing to do in add_extra_ref(). Disable it.

estimate_cache_size() tries to guess how much memory is needed for the
in-memory representation of an index file. It does that by using the
file size, the number of entries and the difference of the sizes of the
on-disk and in-memory structs -- without having to check the length of
the name of each entry, which varies for each entry, but their sums are
the same no matter the representation.
Except there can be a difference. First of all, the size is really
calculated by ce_size and ondisk_ce_size based on offsetof(..., name),
not sizeof, which can be different. And entries are padded with 1 to 8
NULs at the end (after the variable name) to make their total length a
multiple of eight.
So in order to allocate enough memory to hold the index, change the
delta calculation to be based on offsetof(..., name) and round up to
the next multiple of eight.
On a 32-bit Linux, this delta was used before:
sizeof(struct cache_entry) == 72
sizeof(struct ondisk_cache_entry) == 64
---
8
The actual difference for an entry with a filename length of one was,
however (find the definitions are in cache.h):
offsetof(struct cache_entry, name) == 72
offsetof(struct ondisk_cache_entry, name) == 62
ce_size == (72 + 1 + 8) & ~7 == 80
ondisk_ce_size == (62 + 1 + 8) & ~7 == 64
---
16
So eight bytes less had been allocated for such entries. The new
formula yields the correct delta:
(72 - 62 + 7) & ~7 == 16
