Now, ref-filter is using pretty.c logic for setting trailer options.
New to ref-filter:
:key=<K> - only show trailers with specified key.
:valueonly[=val] - only show the value part.
:separator=<SEP> - inserted between trailer lines.
:key_value_separator=<SEP> - inserted between key and value in trailer lines
Enhancement to existing options(now can take value and its optional):
:only[=val]
:unfold[=val]
'val' can be: true, on, yes or false, off, no.

As we would like to use this trailers logic in the ref-filter, it's
nice to get an invalid trailer argument. This will allow us to print
precise error message while using `format_set_trailers_options()` in
ref-filter.
For capturing the invalid argument, we changed the working of
`format_set_trailers_options()` a little bit.
Original logic does "break" and fell through in mainly 2 cases -
1. unknown/invalid argument
2. end of the arg string
But now instead of "break", we capture invalid argument and return
non-zero. And non-zero is handled by the caller.
(We prepared the caller to handle non-zero in the previous commit).
Capturing invalid arguments this way will also affects the working
of current logic. As at the end of the arg string it will return non-zero.
So in order to make things correct, introduced an additional conditional
statement i.e if encounter ")", do 'break'.

diffcore_rename() had some code to avoid having destination paths that
already had an exact rename detected from being re-checked for other
renames. Source paths, however, were re-checked because we wanted to
allow the possibility of detecting copies. But if copy detection isn't
turned on, then this merely amounts to attempting to find a
better-than-exact match, which naturally ends up being an expensive
no-op. In particular, copy detection is never turned on by the merge
machinery.

It can sometimes be useful to see which refs are contributing to the
overall repository size (e.g., does some branch have a bunch of objects
not found elsewhere in history, which indicates that deleting it would
shrink the size of a clone).
You can find that out by generating a list of objects, getting their
sizes from cat-file, and then summing them, like:
git rev-list --objects --no-object-names main..branch
git cat-file --batch-check='%(objectsize:disk)' |
perl -lne '$total += $_; END { print $total }'
Though note that the caveats from git-cat-file(1) apply here. We "blame"
base objects more than their deltas, even though the relationship could
easily be flipped. Still, it can be a useful rough measure.
But one problem is that it's slow to run. Teaching rev-list to sum up
the sizes can be much faster for two reasons:
1. It skips all of the piping of object names and sizes.
2. If bitmaps are in use, for objects that are in the
bitmapped packfile we can skip the oid_object_info()
lookup entirely, and just ask the revindex for the
on-disk size.
This patch implements a --disk-usage option which produces the same
answer in a fraction of the time. Here are some timings using a clone of
torvalds/linux:
[rev-list piped to cat-file, no bitmaps]
$ time git rev-list --objects --no-object-names --all |
git cat-file --buffer --batch-check='%(objectsize:disk)' |
perl -lne '$total += $_; END { print $total }'
1459938510
real 0m29.635s
user 0m38.003s
sys 0m1.093s
[internal, no bitmaps]
$ time git rev-list --disk-usage --objects --all
1459938510
real 0m31.262s
user 0m30.885s
sys 0m0.376s
Even though the wall-clock time is slightly worse due to parallelism,
notice the CPU savings between the two. We saved 21% of the CPU just by
avoiding the pipes.
But the real win is with bitmaps. If we use them without the new option:
[rev-list piped to cat-file, bitmaps]
$ time git rev-list --objects --no-object-names --all --use-bitmap-index |
git cat-file --batch-check='%(objectsize:disk)' |
perl -lne '$total += $_; END { print $total }'
1459938510
real 0m6.244s
user 0m8.452s
sys 0m0.311s
then we're faster to generate the list of objects, but we still spend a
lot of time piping and looking things up. But if we do both together:
[internal, bitmaps]
$ time git rev-list --disk-usage --objects --all --use-bitmap-index
1459938510
real 0m0.219s
user 0m0.169s
sys 0m0.049s
then we get the same answer much faster.
For "--all", that answer will correspond closely to "du objects/pack",
of course. But we're actually checking reachability here, so we're still
fast when we ask for more interesting things:
$ time git rev-list --disk-usage --use-bitmap-index v5.0..v5.10
374798628
real 0m0.429s

Fix a memory leak in 296d4a94e7 (diff: add -I<regex> that ignores
matching changes, 2020-10-20) by freeing the memory it allocates in
the newly introduced diff_free(). See the previous commit for details
on that.
This memory leak was intentionally introduced in 296d4a94e7, see the
discussion on a previous iteration of it in
https://lore.kernel.org/git/xmqqeelycajx.fsf@gitster.c.googlers.com/
At that time freeing the memory was somewhat tedious, but since it
isn't anymore with the newly introduced diff_free() let's use it.
Let's retain the pattern for diff_free_file() and add a
diff_free_ignore_regex(), even though (unlike "diff_free_file") we
don't need to call it elsewhere. I think this'll make for more
readable code than gradually accumulating a giant diff_free()
function, sharing "int i" across unrelated code etc.

Add a diff_free() function to free anything we may have allocated in
the "diff_options" struct, and the ability to make calling it a noop
by setting "no_free" in "diff_options".
This is required because when e.g. "git diff" is run we'll allocate
things in that struct, use the diff machinery once, and then exit.
But if we run e.g. "git log -p" we're going to re-use what we
allocated across multiple diff_flush() calls, and only want to free
things at the end.
We've thus ended up with features like the recently added "diff -I"[1]
where we'll leak memory. As it turns out it could have simply used the
pattern established in 6ea57703f6 (log: prepare log/log-tree to reuse
the diffopt.close_file attribute, 2016-06-22).
Manually adding more such flags to things log_tree_commit() every time
we need to allocate something would be tedious. Let's instead move
that fclose() code it to a new diff_free(), in anticipation of freeing
more things in that function in follow-up commits.
Some functions such as log_tree_commit() need an idiom of optionally
retaining a previous "no_free", as they may either free the memory
themselves, or their caller may do so. I'm keeping that idiom in
log_show_early() for good measure, even though I don't think it's
currently called in this manner. It also gets passed an existing
"struct rev_info", so future callers may want to set the "no_free"
flag.
This change is a bit hard to read because while the freeing pattern
we're introducing isn't unusual, the "file" member is a special
snowflake. We usually don't want to fclose() it. This is because
"file" is usually stdout, in which case we don't want to fclose()
it. We only want to opt-in to closing it when we e.g. open a file on
the filesystem. Thus the opt-in "close_file" flag.
So the API in general just needs a "no_free" flag to defer freeing,
but the "file" member still needs its "close_file" flag. This is made
more confusing because while refactoring this code we could replace
some "close_file=0" with "no_free=1", whereas others need to set both
flags.
This is because there were some cases where an existing "close_file=0"
meant "let's defer deallocation", and others where it meant "we don't
want to close this file handle at all".

we'll also sign tags with headers as well. Let's refactor out a
function called parse_buffer_signed_by_header which does exactly that.
In addition, since we'll want to sign things other than commits this
way, let's call the function sign_with_header instead of do_sign_commit.

We have a function which parses a buffer with a signature at the end,
parse_signature, and this function is used for signed tags. However,
we'll need to store values for multiple algorithms, and we'll do this by
using a header for the non-default algorithm.
Adjust the parse_signature interface to store the parsed data in two
strbufs and turn the existing function into parse_signed_buffer. The
latter is still used in places where we know we always have a signed
buffer, such as push certs.
Adjust all the callers to deal with this new interface.
