structure definition and applying the following semantic patch:

* [PATCH 10/17] Convert remaining callers of resolve_refdup to object_id
From: brian m. carlson @ 2017-01-01 19:18 UTC (permalink / raw)
To: git; +Cc: Jeff King, Michael Haggerty
In-Reply-To: <20170101191847.564741-1-sandals@crustytoothpaste.net>
There are a few leaf functions in various files that call
resolve_refdup. Convert these functions to use struct object_id
internally to prepare for transitioning resolve_refdup itself.

* [PATCH 13/17] refs: convert each_reflog_ent_fn to struct object_id
From: brian m. carlson @ 2017-01-01 19:18 UTC (permalink / raw)
To: git; +Cc: Jeff King, Michael Haggerty
In-Reply-To: <20170101191847.564741-1-sandals@crustytoothpaste.net>
Make each_reflog_ent_fn take two struct object_id pointers instead of
two pointers to unsigned char. Convert the various callbacks to use
struct object_id as well. Also, rename fsck_handle_reflog_sha1 to
fsck_handle_reflog_oid.

* [PATCH 15/17] Convert object iteration callbacks to struct object_id
From: brian m. carlson @ 2017-01-01 19:18 UTC (permalink / raw)
To: git; +Cc: Jeff King, Michael Haggerty
In-Reply-To: <20170101191847.564741-1-sandals@crustytoothpaste.net>
Convert each_loose_object_fn and each_packed_object_fn to take a pointer
to struct object_id. Update the various callbacks. Convert several
40-based constants to use GIT_SHA1_HEXSZ.

* [PATCH 14/17] sha1_file: introduce an nth_packed_object_oid function
From: brian m. carlson @ 2017-01-01 19:18 UTC (permalink / raw)
To: git; +Cc: Jeff King, Michael Haggerty
In-Reply-To: <20170101191847.564741-1-sandals@crustytoothpaste.net>
There are places in the code where we would like to provide a struct
object_id *, yet read the hash directly from the pack. Provide an
nth_packed_object_oid function that mirrors the nth_packed_object_sha1
function.
The required cast is questionable, but should be safe on all known
platforms. The alternative of allocating an object as an intermediate
would be too inefficient and cause memory leaks. If necessary, an
intermediate union could be used; this practice is allowed by GCC and
explicitly sanctioned by C11. However, such a change will likely not be
necessary, and can be made if and when it is.

* [PATCH 11/17] builtin/replace: convert to struct object_id
From: brian m. carlson @ 2017-01-01 19:18 UTC (permalink / raw)
To: git; +Cc: Jeff King, Michael Haggerty
In-Reply-To: <20170101191847.564741-1-sandals@crustytoothpaste.net>
Convert various uses of unsigned char [20] to struct object_id. Rename
replace_object_sha1 to rename_object_oid. Finally, specify a constant
in terms of GIT_SHA1_HEXSZ.

* [PATCH 00/17] object_id part 6
From: brian m. carlson @ 2017-01-01 19:18 UTC (permalink / raw)
To: git; +Cc: Jeff King, Michael Haggerty
This is another series in the continuing conversion to struct object_id.
This series converts more of the builtin directory and some of the
refs code to use struct object_id. Additionally, it implements an
nth_packed_object_oid function which provides a struct object_id
version of the nth_packed_object function.
There is a small known conflict with next, but it can easily be fixed up.
brian m. carlson (17):
builtin/commit: convert to struct object_id
builtin/diff-tree: convert to struct object_id
builtin/describe: convert to struct object_id
builtin/fast-export: convert to struct object_id
builtin/fmt-merge-message: convert to struct object_id
builtin/grep: convert to struct object_id
builtin/branch: convert to struct object_id
builtin/clone: convert to struct object_id
builtin/merge: convert to struct object_id
Convert remaining callers of resolve_refdup to object_id
builtin/replace: convert to struct object_id
reflog-walk: convert struct reflog_info to struct object_id
refs: convert each_reflog_ent_fn to struct object_id
sha1_file: introduce an nth_packed_object_oid function
Convert object iteration callbacks to struct object_id

you please squash this into the relevant patch (commit 8a7e3ef9a6,

The invoked bisect_next shell code called "exit", right... you had to
replace this by passing return values. I get it. Thank you!

"checkout the next bisection commit" maybe?

The message is actually part of a template presented to the user via
their chosen editor. For this test, we set the editor to be "cat", so
it comes out on stdout.
Your first suggestion would therefore be fine (and similarly for the
other cases).

No. The exit code of the upstream in a pipe is ignored. For this reason,
having a git invocation as the upstream of a pipe *anywhere* in the test
suite is frowned upon. Hence, a better rewrite would be
git p4 commit >actual &&
! grep "git author.*does not match" actual &&
which makes me wonder: Is the message that we do expect not to occur

Would it be clearer to use this?
git p4 commit |\
grep -q -v "git author.*does not match" &&
With your original change, I think that if "git p4 commit" fails, then
that expression will be treated as a pass. What we want is for "git p4
commit" to pass, but the string to be missing.
(I would have used "--invert-match" rather than "-v", but it seems
that's not supported on Solaris).

It is easily possible in the Windows environment where the install philosphy
is different, and some external vendor tools may even bring in their own
copy of Git as well. There is also the Portable Git version, so the
possibility of multiple versions running concurrently is there, though it is
on Windows...
I certainly have a Git-for-Windows published version, and a recent SDK
version on my home machines.

FWIW, in my mental model, 2. is not a failure ("we returned without
creating new log because that is what was asked by the user"). A
true failure case is "we wanted to open but couldn't".
The caller needs to be able to differentiate between these two cases
because we get no usable fd out of the function in either case.
I agree that we could cram the error status and the file descriptor
into a single return value as you two discussed, but I think what
the patch chose to do is easier to use from the callers' point of
view. The caller can switch between the codepath to give an error
message and the non-error codepath based on the return value, and in
the non-error codepath can choose what to do based on the value of
logfd.
I do not mind "all negative values mean there is no fd" plus "some
negative values are more special than others" convention, and if a
patch did that from the beginning, I certainly would not suggest to
rewrite it to use the "error status comes as a return value, file
descriptor is an out parameter" convention; i.e. I personally do not
see much difference either way, so...

The first thing you can do is to run the test with debug and verbose:
debug=t verbose=t ./t7810-grep.sh
and post the output of these 2 test cases here:
(mine looks like this)
expecting success:
echo "ab:a+bc" >expected &&
git \
-c grep.patterntype=extended \
-c grep.patterntype=fixed \
-c grep.patterntype=basic \
grep "a+b*c" ab >actual &&
test_cmp expected actual
ok 142 - grep pattern with grep.patternType=extended, =fixed, =basic
expecting success:
echo "ab:abc" >expected &&
git grep -F -G -E "a+b*c" ab >actual &&
test_cmp expected actual
ok 143 - grep -F -G -E pattern

To add to this, if it is possible, it might be worth merging the "make
ourselves safer against a race" first, and then waiting some time
before merging the "we are now safe to delete directories". I am not
yet convinced that it is necessary, but wanted to point it out so that
someone more knowledgeable could explain why it is safe to do so.

I do have one comment regarding this series. Is it ever possible for
an older version of git to be running a process while a new version of
git which cleans up dirs runs? Is this expected? I just want to make
sure we don't need to worry about that scenario since otherwise it
makes it much more challenge.
My thought as far as I understand it is that it is possible, because a
user COULD choose to run both this and an older version, but that it
is unlikely in practice outside of a few developer boxes who
periodically switch between versions of git, and are unlikely to
actually run multiple versions at exactly the same time.
Thanks,
Jake

That's a form of superstition that I haven't encountered before ;-) but
I'll change it.

Git garden shears, perhaps?
