The document says one cannot push from a shallow clone. But that is
not true (maybe it was at some point in the past). The client does not
stop such a push nor does it give any indication to the receiver that
this is a shallow push. If the receiver accepts it, it's in.
Since 52fed6e (receive-pack: check connectivity before concluding "git

Each caller of sha1_object_info_extended sets up an
object_info struct to tell the function which elements of
the object it wants to get. Until now, getting the type of
the object has always been required (and it is returned via
the return type rather than a pointer in object_info).
This can involve actually opening a loose object file to
determine its type, or following delta chains to determine a
packed file's base type. These effects produce a measurable
slow-down when doing a "cat-file --batch-check" that does
not include %(objecttype).
This patch adds a "typep" query to struct object_info, so
that it can be optionally queried just like size and
disk_size. As a result, the return type of the function is
no longer the object type, but rather 0/-1 for success/error.
As there are only three callers total, we just fix up each
caller rather than keep a compatibility wrapper:
1. The simpler sha1_object_info wrapper continues to
always ask for and return the type field.
2. The istream_source function wants to know the type, and
so always asks for it.
3. The cat-file batch code asks for the type only when
%(objecttype) is part of the format string.
On linux.git, the best-of-five for running:
$ git rev-list --objects --all >objects
$ time git cat-file --batch-check='%(objectsize:disk)'
on a fully packed repository goes from:
real 0m8.680s
user 0m8.160s
sys 0m0.512s
to:
real 0m7.205s

Currently, packed_object_info can save some work by not
calculating the size or disk_size of the object if the
caller is not interested. However, it always calculates the
true object type, whether the caller cares or not, and only
optionally returns the easy-to-get "representation type".
Let's swap these types. The function will now return the
representation type (or OBJ_BAD on failure), and will only
optionally fill in the true type.
There should be no behavior change yet, as the only caller,
sha1_object_info_extended, will always feed it a type
pointer.

To calculate the type of a packed object, we must walk down
its delta chain until we hit a true base object with a real
type. Most of the code in packed_object_info is for handling
this case.
Let's hoist it out into a separate helper function, which
will make it easier to make the type-lookup optional in the
future (and keep our indentation level sane).

Until recently, the only items to request from
sha1_object_info_extended were type and size. This meant
that we always had to open a loose object file to determine
one or the other. But with the addition of the disk_size
query, it's possible that we can fulfill the query without
even opening the object file at all. However, since the
function interface always returns the type, we have no way
of knowing whether the caller cares about it or not.
This patch only modified sha1_loose_object_info to make type
lookup optional using an out-parameter, similar to the way
the size is handled (and the return value is "0" or "-1" for
success or error, respectively).
There should be no functional change yet, though, as
sha1_object_info_extended, the only caller, will always ask
for a type.

A common use of "cat-file --batch-check" is to feed a list
of objects from "rev-list --objects" or a similar command.
In this instance, all of our input objects are 40-byte sha1
ids. However, cat-file has always allowed arbitrary revision
specifiers, and feeds the result to get_sha1().
Fortunately, get_sha1() recognizes a 40-byte sha1 before
doing any hard work trying to look up refs, meaning this
scenario should end up spending very little time converting
the input into an object sha1. However, since 798c35f
(get_sha1: warn about full or short object names that look
like refs, 2013-05-29), when we encounter this case, we
spend the extra effort to do a refname lookup anyway, just
to print a warning. This is further exacerbated by ca91993
(get_packed_ref_cache: reload packed-refs file when it
changes, 2013-06-20), which makes individual ref lookup more
expensive by requiring a stat() of the packed-refs file for
each missing ref.
With no patches, this is the time it takes to run:
$ git rev-list --objects --all >objects
$ time git cat-file --batch-check='%(objectname)' <objects
on the linux.git repository:
real 1m13.494s
user 0m25.924s
sys 0m47.532s
If we revert ca91993, the packed-refs up-to-date check, it
gets a little better:
real 0m54.697s
user 0m21.692s
sys 0m32.916s
but we are still spending quite a bit of time on ref lookup
(and we would not want to revert that patch, anyway, which
has correctness issues). If we revert 798c35f, disabling
the warning entirely, we get a much more reasonable time:
real 0m7.452s
user 0m6.836s
sys 0m0.608s
This patch does the moral equivalent of this final case (and
gets similar speedups). We introduce a global flag that
callers of get_sha1() can use to avoid paying the price for
the warning.

To test check-ignore's --stdin feature, we use two fifos to
send and receive data. We carefully keep a descriptor to its
input open so that it does not receive EOF between input
lines. However, we do not do the same for its output. That
means there is a potential race condition in which
check-ignore has opened the output pipe once (when we read
the first line), and then writes the second line before we
have re-opened the pipe.
In that case, check-ignore gets a SIGPIPE and dies. The
outer shell then tries to open the output fifo but blocks
indefinitely, because there is no writer. We can fix it by
keeping a descriptor open through the whole procedure.
This should also help if check-ignore dies for any other
reason (we would already have opened the fifo and would
therefore not block, but just get EOF on read).
However, we are technically still susceptible to
check-ignore dying early, before we have opened the fifo.
This is an unlikely race and shouldn't generally happen in
practice, though, so we can hopefully ignore it.

The pack revindex stores the offsets of the objects in the
pack in sorted order, allowing us to easily find the on-disk
size of each object. To compute it, we populate an array
with the offsets from the sha1-sorted idx file, and then use
qsort to order it by offsets.
That does O(n log n) offset comparisons, and profiling shows
that we spend most of our time in cmp_offset. However, since
we are sorting on a simple off_t, we can use numeric sorts
that perform better. A radix sort can run in O(k*n), where k
is the number of "digits" in our number. For a 64-bit off_t,
using 16-bit "digits" gives us k=4.
On the linux.git repo, with about 3M objects to sort, this
yields a 400% speedup. Here are the best-of-five numbers for
running
echo HEAD | git cat-file --batch-check="%(objectsize:disk)
on a fully packed repository, which is dominated by time
spent building the pack revindex:
before after
real 0m0.834s 0m0.204s
user 0m0.788s 0m0.164s
sys 0m0.040s 0m0.036s
This matches our algorithmic expectations. log(3M) is ~21.5,
so a traditional sort is ~21.5n. Our radix sort runs in k*n,
where k is the number of radix digits. In the worst case,
this is k=4 for a 64-bit off_t, but we can quit early when
the largest value to be sorted is smaller. For any
repository under 4G, k=2. Our algorithm makes two passes
over the list per radix digit, so we end up with 4n. That
should yield ~5.3x speedup. We see 4x here; the difference
is probably due to the extra bucket book-keeping the radix
sort has to do.
On a smaller repo, the difference is less impressive, as
log(n) is smaller. For git.git, with 173K objects (but still
k=2), we see a 2.7x improvement:
before after
real 0m0.046s 0m0.017s
user 0m0.036s 0m0.012s
sys 0m0.008s 0m0.000s
On even tinier repos (e.g., a few hundred objects), the
speedup goes away entirely, as the small advantage of the
radix sort gets erased by the book-keeping costs (and at
those sizes, the cost to generate the the rev-index gets
lost in the noise anyway).

A packfile may have up to 2^32-1 objects in it, so the
"right" data type to use is uint32_t. We currently use a
signed int, which means that we may behave incorrectly for
packfiles with more than 2^31-1 objects on 32-bit systems.
Nobody has noticed because having 2^31 objects is pretty
insane. The linux.git repo has on the order of 2^22 objects,
which is hundreds of times smaller than necessary to trigger
the bug.
Let's bump this up to an "unsigned". On 32-bit systems, this
gives us the correct data-type, and on 64-bit systems, it is
probably more efficient to use the native "unsigned" than a
true uint32_t.
While we're at it, we can fix the binary search not to
overflow in such a case if our unsigned is 32 bits.

If we get an input line to --batch or --batch-check that
looks like "HEAD foo bar", we will currently feed the whole
thing to get_sha1(). This means that to use --batch-check
with `rev-list --objects`, one must pre-process the input,
like:
git rev-list --objects HEAD |
cut -d' ' -f1 |
git cat-file --batch-check
Besides being more typing and slightly less efficient to
invoke `cut`, the result loses information: we no longer
know which path each object was found at.
This patch teaches cat-file to split input lines at the
first whitespace. Everything to the left of the whitespace
is considered an object name, and everything to the right is
made available as the %(reset) atom. So you can now do:
git rev-list --objects HEAD |
git cat-file --batch-check='%(objectsize) %(rest)'
to collect object sizes at particular paths.
Even if %(rest) is not used, we always do the whitespace
split (which means you can simply eliminate the `cut`
command from the first example above).
This whitespace split is backwards compatible for any
reasonable input. Object names cannot contain spaces, so any
input with spaces would have resulted in a "missing" line.
The only input hurt is if somebody really expected input of
the form "HEAD is a fine-looking ref!" to fail; it will now
parse HEAD, and make "is a fine-looking ref!" available as
%(rest).

This atom is just like %(objectsize), except that it shows
the on-disk size of the object rather than the object's true
size. In other words, it makes the "disk_size" query of
sha1_object_info_extended available via the command-line.
This can be used for rough attribution of disk usage to
particular refs, though see the caveats in the
documentation.
This patch does not include any tests, as the exact numbers
returned are volatile and subject to zlib and packing
decisions. We cannot even reliably guarantee that the
on-disk size is smaller than the object content (though in
general this should be the case for non-trivial objects).

The `cat-file --batch-check` command can be used to quickly
get information about a large number of objects. However, it
provides a fixed set of information.
This patch adds an optional <format> option to --batch-check
to allow a caller to specify which items they are interested
in, and in which order to output them. This is not very
exciting for now, since we provide the same limited set that
you could already get. However, it opens the door to adding
new format items in the future without breaking backwards
compatibility (or forcing callers to pay the cost to
calculate uninteresting items).
Since the --batch option shares code with --batch-check, it
receives the same feature, though it is less likely to be of
interest there.
The format atom names are chosen to match their counterparts
in for-each-ref. Though we do not (yet) share any code with
for-each-ref's formatter, this keeps the interface as
consistent as possible, and may help later on if the
implementations are unified.

. 'simple' is meant to help new people by avoiding mistakes, and
will be the safe default in Git 2.0.
In a non-triangular workflow, it will continue to act as a cross
between 'upstream' and 'current' in that it pushes to the current
branch's @{upstream} only when it is set to the same name as the
current branch (e.g. your 'master' forks from the 'master' from

t4211 attempts to test multiple git-log -L ranges where one range is a

Overlapping -L ranges handed to git-log are coalesced by
line-log.c:sort_and_merge_range_set() into a set of non-overlapping,
disjoint ranges. When one range is a subset of another,
sort_and_merge_range_set() should coalesce both ranges to the superset
range, but instead the coalesced range often is incorrectly truncated to
the end of the subset range. For example, ranges 2-8 and 3-4 are
coalesced incorrectly to 2-4.
One can observe this incorrect behavior with git-log -L using the test

are 4-$ and 8-12 (where $ represents end-of-file). The coalesced range

to find out how existing entries in index are modified and where. The
question I have is what do we do if we really need to keep track of on-disk
changes in the index. The result is
- diff-lib.c: setting CE_UPTODATE
- name-hash.c: setting CE_HASHED
- preload-index.c, read-cache.c, unpack-trees.c and
builtin/update-index: obvious
- entry.c: write_entry() may refresh the checked out entry via
fill_stat_cache_info(). This causes "non-const struct cache_entry
*" in builtin/apply.c, builtin/checkout-index.c and
builtin/checkout.c
- builtin/ls-files.c: --with-tree changes stagemask and may set
CE_UPDATE
Of these, write_entry() and its call sites are probably most
interesting because it modifies on-disk info. But this is stat info
and can be retrieved via refresh, at least for porcelain
commands. Other just uses ce_flags for local purposes.
So, keeping track of "dirty" entries is just a matter of setting a
flag in index modification functions exposed by read-cache.c. Except
unpack-trees, the rest of the code base does not do anything funny
behind read-cache's back.
The actual patch is less valueable than the summary above. But if
anyone wants to re-identify the above sites. Applying this patch, then
this:

Unicode clause D14 defines all characters U+nFFFE and U+nFFFF (where
0 <= n <= 10h) as well as the range U+FDD0..U+FDEF as non-characters,
reserved for internal use only. Disallow these characters in commit
messages as they are normally not recommended for interchange.

Instead of using a hand allocated args[] array, use argv-array API
to manage the dynamically created list of arguments when invoking
name-rev.

"git name-rev" is supposed to convert given object names into
strings that name the same objects based on refs, that can be fed to
"git rev-parse" to get the same object names back, so the output for
the commit object v1.8.3^0 (i.e. the commit tagged as v1.8.3)
$ git rev-parse v1.8.3 v1.8.3^0 | git name-rev --stdin
8af06057d0c31a24e8737ae846ac2e116e8bafb9
edca415256 (tags/v1.8.3^0)
has to have "^0" at the end, as "edca41" is a commit, not the tag
that references it. But we do not get anything for the tag object
(8af0605) itself.
This is because the command however did not bother to see if the
object is at the tip of some ref, and failed to convert a tag
object.
Teach it to show this instead:
$ git rev-parse v1.8.3 v1.8.3^0 | git name-rev --stdin
8af06057d0c31a24e8737ae846ac2e116e8bafb9 (tags/v1.8.3)
edca415256 (tags/v1.8.3^0)
