In the original ref-filter design, it will copy the parsed
atom's name and attributes to `used_atom[i].name` in the
atom's parsing step, and use it again for string matching
in the later specific ref attributes filling step. It use
a lot of string matching to determine which atom we need.
Introduce the enum "atom_type", each enum value is named
as `ATOM_*`, which is the index of each corresponding
valid_atom entry. In the first step of the atom parsing,
`used_atom.atom_type` will record corresponding enum value
from valid_atom entry index, and then in specific reference
attribute filling step, only need to compare the value of
the `used_atom[i].atom_type` to check the atom type.

When the support for "objectsize:disk" was bolted onto the
existing support for "objectsize", it didn't follow the
usual pattern for handling "atomtype:modifier", which reads
the <modifier> part just once while parsing the format
string, and store the parsed result in the union in the
used_atom structure, so that the string form of it does not
have to be parsed over and over at runtime (e.g. in
grab_common_values()).
Add a new member `objectsize` to the union `used_atom.u`,
so that we can separate the check of <modifier> from the
check of <atomtype>, this will bring scalability to atom
`%(objectsize)`.

A NULL-dereference bug has been corrected in an error codepath in
"git for-each-ref", "git branch --list" etc.
* jk/ref-filter-segfault-fix:
ref-filter: fix NULL check for parse object failure
After we run parse_object_buffer() to get an object's contents, we try
to check that the return value wasn't NULL. However, since our "struct
object" is a pointer-to-pointer, and we assign like:
*obj = parse_object_buffer(...);
it's not correct to check:
if (!obj)
That will always be true, since our double pointer will continue to
point to the single pointer (which is itself NULL). This is a regression
that was introduced by aa46a0da30 (ref-filter: use oid_object_info() to
get object, 2018-07-17); since that commit we'll segfault on a parse
failure, as we try to look at the NULL object pointer.
There are many ways a parse could fail, but most of them are hard to set
up in the tests (it's easy to make a bogus object, but update-ref will
refuse to point to it). The test here uses a tag which points to a wrong
object type. A parse of just the broken tag object will succeed, but
seeing both tag objects in the same process will lead to a parse error
(since we'll see the pointed-to object as both types).

signed.

ref-filter: switch some uses of unsigned long to size_t
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]

Adjust the parse_signature interface to store the parsed data in two

common prefix of among a set of refspecs, and then to iterate all of the
references that descend from that prefix.
A future patch will want to use that same code from ls-refs.c, so
prepare by exposing and moving it to refs.c. Since there is nothing
specific to the ref-filter code here (other than that it was previously
the only caller of this function), this really belongs in the more
generic refs.h header.

It doesn't make any sense to consider the objectsize, type or other
non-attribute of the "(HEAD detached at <hash>)" message for the
purposes of sorting. Let's always emit it at the top instead. The only
reason it was sorted in the first place is because we're injecting it
into the ref-filter machinery so builtin/branch.c doesn't need to do
its own "am I detached?" detection.

Change the ref-filter sorting of detached HEAD to check the
FILTER_REFS_DETACHED_HEAD flag, instead of relying on the ref
description filled-in by get_head_description() to start with "(",
which in turn we expect to ASCII-sort before any other reference.
For context, we'd like the detached line to appear first at the start
of "git branch -l", e.g.:
$ git branch -l
* (HEAD detached at <hash>)
master
This doesn't change that, but improves on a fix made in
28438e84e0 (ref-filter: sort detached HEAD lines firstly, 2019-06-18)
and gives the Chinese translation the ability to use its preferred
punctuation marks again.
In Chinese the fullwidth versions of punctuation like "()" are
typically written as (U+FF08 fullwidth left parenthesis), (U+FF09
fullwidth right parenthesis) instead[1]. This form is used in both
po/zh_{CN,TW}.po in most cases where "()" is translated in a string.
Aside from that improvement to the Chinese translation, it also just
makes for cleaner code that we mark any special cases in the ref_array
we're sorting with flags and make the sort function aware of them,
instead of piggy-backing on the general-case of strcmp() doing the
right thing.
As seen in the amended tests this made reverse sorting a bit more
consistent. Before this we'd sometimes sort this message in the
middle, now it's consistently at the beginning or end, depending on
whether we're doing a normal or reverse sort. Having it at the end
doesn't make much sense either, but at least it behaves consistently
now. A follow-up commit will make this behavior under reverse sorting
even better.
I'm removing the "TRANSLATORS" comments that were in the old code
while I'm at it. Those were added in d4919bb288 (ref-filter: move
get_head_description() from branch.c, 2017-01-10). I think it's
obvious from context, string and translation memory in typical
translation tools that these are the same or similar string.

Change the reverse/ignore_case/version sort flags in the ref_sorting

function like ref_sorting_icase_all() introduced in
76f9e569ad (ref-filter: apply --ignore-case to all sorting keys,

A follow-up change will introduce such a flag, so let's move this over
to a bitfield. Instead of using the usual '#define' pattern I'm using
the "enum" pattern from builtin/rebase.c's b4c8eb024a (builtin
rebase: support --quiet, 2018-09-04).
Perhaps there's a more idiomatic way of doing the "for each in list
amend mask" pattern than this "mask/on" variable combo. This function
doesn't allow us to e.g. do any arbitrary changes to the bitfield for
multiple flags, but I think in this case that's fine. The common case

- hashmap_clear_and_free() - ditto, but free the entries themselves
- hashmap_partial_clear() - remove all entries but don't deallocate
table
- hashmap_partial_clear_and_free() - ditto, but free the entries
This patch provides the new names and converts all existing callers over

The ref-filter code does not correctly handle commit or tag messages
that use CRLF as the line terminator. Such messages can be created with
the `--cleanup=verbatim` option of `git commit` and `git tag`, or by
using `git commit-tree` directly.
The function `find_subpos` in ref-filter.c looks for two consecutive
LFs to find the end of the subject line, a sequence which is absent in
messages using CRLF. This results in the whole message being parsed as
the subject line (`%(contents:subject)`), and the body of the message
(`%(contents:body)`) being empty.
Moreover, in `copy_subject`, which wants to return the subject as a
single line, '\n' is replaced by space, but '\r' is
untouched.
This impacts the output of `git branch`, `git tag` and `git
for-each-ref`.
This behaviour is a regression for `git branch --verbose`, which
bisects down to 949af0684c (branch: use ref-filter printing APIs,
2017-01-10).
Adjust the ref-filter code to be more lenient by hardening the logic in
`copy_subject` and `find_subpos` to correctly parse messages containing
CRLF.
Add a new test script, 't3920-crlf-messages.sh', to test the behaviour
of commands using either the ref-filter or the pretty APIs with messages
using CRLF line endings. The function `test_crlf_subject_body_and_contents`
can be used to test that the `--format` option of `branch`, `tag`,
`for-each-ref`, `log` and `show` correctly displays the subject, body
and raw content of commit and tag messages using CRLF. Test the
output of `branch`, `tag` and `for-each-ref` with such commits.

wt-status: introduce wt_status_state_free_buffers()

When we have a `struct wt_status_state`, we manually free its `branch`,
`onto` and `detached_from`, or sometimes just one or two of them.
Provide a function `wt_status_state_free_buffers()` which does the
freeing.
The callers are still aware of these fields, e.g., they check whether
`branch` was populated or not. But this way, they don't need to know
about *all* of them, and if `struct wt_status_state` gets more fields,
they will not need to learn to free them.
Users of `struct wt_status` (which contains a `wt_status_state`) already
have `wt_status_collect_free_buffers()` (corresponding to
`wt_status_collect()`) which we can also teach to use this new helper.
Finally, note that we're currently leaving dangling pointers behind.
Some callers work on a stack-allocated struct, where this is obviously
ok. But for the users of `run_status()` in builtin/commit.c, there are
ample opportunities for someone to mistakenly use those dangling
pointers. We seem to be ok for now, but it's a use-after-free waiting to
happen. Let's leave NULL-pointers behind instead.

It's useful and efficient to be able to get the size of the
contents directly without having to pipe through `wc -c`.
Also the result of the following:
`git for-each-ref --format='%(contents)' refs/heads/my-branch | wc -c`
is off by one as `git for-each-ref` appends a newline character
after the contents, which can be seen by comparing its output
with the output from `git cat-file`.
As with %(contents), %(contents:size) is silently ignored, if a
ref points to something other than a commit or a tag:
```
$ git update-ref refs/mytrees/first HEAD^{tree}
$ git for-each-ref --format='%(contents)' refs/mytrees/first
$ git for-each-ref --format='%(contents:size)' refs/mytrees/first

"git branch" and other "for-each-ref" variants accepted multiple
--sort=<key> options in the increasing order of precedence, but it
had a few breakages around "--ignore-case" handling, and tie-breaking
with the refname, which have been fixed.
* jk/for-each-ref-multi-key-sort-fix:
ref-filter: apply fallback refname sort only after all user sorts
ref-filter: apply --ignore-case to all sorting keys
Commit 9e468334b4 (ref-filter: fallback on alphabetical comparison,
2015-10-30) taught ref-filter's sort to fallback to comparing refnames.
But it did it at the wrong level, overriding the comparison result for a
single "--sort" key from the user, rather than after all sort keys have
been exhausted.
This worked correctly for a single "--sort" option, but not for multiple
ones. We'd break any ties in the first key with the refname and never
evaluate the second key at all.
To make matters even more interesting, we only applied this fallback
sometimes! For a field like "taggeremail" which requires a string
comparison, we'd truly return the result of strcmp(), even if it was 0.
But for numerical "value" fields like "taggerdate", we did apply the
fallback. And that's why our multiple-sort test missed this: it uses
taggeremail as the main comparison.
So let's start by adding a much more rigorous test. We'll have a set of
commits expressing every combination of two tagger emails, dates, and
refnames. Then we can confirm that our sort is applied with the correct
precedence, and we'll be hitting both the string and value comparators.
That does show the bug, and the fix is simple: moving the fallback to
the outer compare_refs() function, after all ref_sorting keys have been
exhausted.
Note that in the outer function we don't have an "ignore_case" flag, as
it's part of each individual ref_sorting element. It's debatable what
such a fallback should do, since we didn't use the user's keys to match.
But until now we have been trying to respect that flag, so the
least-invasive thing is to try to continue to do so. Since all callers
in the current code either set the flag for all keys or for none, we can
just pull the flag from the first key. In a hypothetical world where the
user really can flip the case-insensitivity of keys separately, we may
want to extend the code to distinguish that case from a blanket
"--ignore-case".

All of the ref-filter users (for-each-ref, branch, and tag) take an
--ignore-case option which makes filtering and sorting case-insensitive.
However, this option was applied only to the first element of the
ref_sorting list. So:
git for-each-ref --ignore-case --sort=refname
would do what you expect, but:
git for-each-ref --ignore-case --sort=refname --sort=taggername
would sort the primary key (taggername) case-insensitively, but sort the
refname case-sensitively. We have two options here:
- teach callers to set ignore_case on the whole list
- replace the ref_sorting list with a struct that contains both the
list of sorting keys, as well as options that apply to _all_
keys
I went with the first one here, as it gives more flexibility if we later
want to let the users set the flag per-key (presumably through some
special syntax when defining the key; for now it's all or nothing
through --ignore-case).
The new test covers this by sorting on both tagger and subject
case-insensitively, which should compare "a" and "A" identically, but
still sort them before "b" and "B". We'll break ties by sorting on the
refname to give ourselves a stable output (this is actually supposed to
be done automatically, but there's another bug which will be fixed in
the next commit).

Commit 9700fae5ee (for-each-ref: let upstream/push report the remote
ref name, 2017-11-07) added a remote_ref_for_branch() helper, which
is modeled after remote_for_branch(). This includes providing an
"explicit" out-parameter that tells the caller whether the remote
was configured by the user, or whether we picked a default name like
"origin".
But unlike remote names, there is no default name when the user
didn't configure one. The only way the "explicit" parameter is used
by the caller is to use the value returned from the helper when it
is set, and use an empty string otherwise, ignoring the returned
value from the helper.
Let's drop the "explicit" out-parameter, and return NULL when the
returned value from the helper should be ignored, to simplify the
function interface.

If a caller sets the object_info.delta_base_sha1 to a non-NULL pointer,
we'll write the oid of the object's delta base to it. But we can
increase our type safety by switching this to a real object_id struct.
All of our callers are just pointing into the hash member of an

Since cfe004a5a9 (ref-filter: limit traversal to prefix, 2017-05-22),
the ref-filter code has sought to limit the traversals to a prefix of
the given patterns.
That code stopped short of handling more than one pattern, because it
means invoking 'for_each_ref_in' multiple times. If we're not careful
about which patterns overlap, we will output the same refs multiple
times.
For instance, consider the set of patterns 'refs/heads/a/*',
'refs/heads/a/b/c', and 'refs/tags/v1.0.0'. If we naïvely ran:
for_each_ref_in("refs/heads/a/*", ...);
for_each_ref_in("refs/heads/a/b/c", ...);
for_each_ref_in("refs/tags/v1.0.0", ...);
we would see 'refs/heads/a/b/c' (and everything underneath it) twice.
Instead, we want to partition the patterns into disjoint sets, where we
know that no ref will be matched by any two patterns in different sets.
In the above, these are:
- {'refs/heads/a/*', 'refs/heads/a/b/c'}, and
- {'refs/tags/v1.0.0'}
Given one of these disjoint sets, what is a suitable pattern to pass to
'for_each_ref_in'? One approach is to compute the longest common prefix
over all elements in that disjoint set, and let the caller cull out the
refs they didn't want. Computing the longest prefix means that in most
cases, we won't match too many things the caller would like to ignore.
The longest common prefixes of the above are:
- {'refs/heads/a/*', 'refs/heads/a/b/c'} -> refs/heads/a/*
- {'refs/tags/v1.0.0'} -> refs/tags/v1.0.0
We instead invoke:
for_each_ref_in("refs/heads/a/*", ...);
for_each_ref_in("refs/tags/v1.0.0", ...);
Which provides us with the refs we were looking for with a minimal
amount of extra cruft, but never a duplicate of the ref we asked for.
Implemented here is an algorithm which accomplishes the above, which
works as follows:
1. Lexicographically sort the given list of patterns.
2. Initialize 'prefix' to the empty string, where our goal is to
build each element in the above set of longest common prefixes.
3. Consider each pattern in the given set, and emit 'prefix' if it
reaches the end of a pattern, or touches a wildcard character. The
end of a string is treated as if it precedes a wildcard. (Note that
there is some room for future work to detect that, e.g., 'a?b' and
'abc' are disjoint).
4. Otherwise, recurse on step (3) with the slice of the list
corresponding to our current prefix (i.e., the subset of patterns
that have our prefix as a literal string prefix.)
This algorithm is 'O(kn + n log(n))', where 'k' is max(len(pattern)) for
each pattern in the list, and 'n' is len(patterns).
By discovering this set of interesting patterns, we reduce the runtime
of multi-pattern 'git for-each-ref' (and other ref traversals) from
O(N) to O(n log(N)), where 'N' is the total number of packed references.
Running 'git for-each-ref refs/tags/a refs/tags/b' on a repository with
10,000,000 refs in 'refs/tags/huge-N', my best-of-five times drop from:
real 0m5.805s
user 0m5.188s
sys 0m0.468s
to:
real 0m0.001s
user 0m0.000s
sys 0m0.000s
On linux.git, the times to dig out two of the latest -rc tags drops from
0.002s to 0.001s, so the change on repositories with fewer tags is much
less noticeable.

Before this patch, "git branch" would put "(HEAD detached...)" and "(no
branch, rebasing...)" lines before all the other branches *in most
cases* except for when using Chinese-language messages. zh_CN generally
uses a full-width "(" symbol (codepoint FF08) to match the full-width
proportions of Chinese characters, and the translated strings we had did
use them. This meant that the detached HEAD line would appear after all
local refs and even after the remote refs if there were any.
AFAIK, it is sometimes not jarring to see the half-width parenthesis in
"full-width" text as in the CJK languages, for instance when there are
no characters preceding or following the parenthesized text fragment. By
removing the parenthesis from the localizable text, we can share strings
with wt-status.c and remove a cautionary comment to translators.
Remove the ( from the localizable portion of messages so the sorting
happens properly regardless of locale.

In ref-filter.c, when processing the atom %(push:track), the

to the upstream branch.
Fix that by introducing a new flag `for_push` in `stat_tracking_info`
in remote.c, which does the same thing but for the push branch.
Update the few callers of `stat_tracking_info` to handle this flag. This
ensure that whenever we use this function in the future, we are careful
to specify is this should apply to the upstream or the push branch.
This bug was not detected in t/t6300-for-each-ref.sh because in the test
for push:track, both the upstream and the push branches were behind by 1
from the local branch. Change the test so that the upstream branch is
behind by 1 while the push branch is ahead by 1. This allows us to test
that %(push:track) refers to the correct branch.
This changes the expected value of some following tests (by introducing
new references), so update them too.

Unfortunately that's a bit tricky due to the way the ref-filter code

- switch to using PARSE_OPT_NONEG in the option definition, which will

- since this was cut-and-pasted to four different spots, let's define
a single OPT_REF_SORT() macro that we can use everywhere
- the callback can use BUG_ON_OPT_NEG() to make sure the correct flags

Many of our grab_* functions, which parse the object content, take a
buf/sz pair of the object bytes. However, the functions which actually
parse the buffers (like find_wholine() and find_subpos()) never look at
"sz", and instead use functions like strchr() and strchrnul() that
assume the result is NUL-terminated.
This is OK in practice (and common for Git's parsing code), since we
always allocate an extra NUL when loading an object into memory (and
likewise, we are OK with stopping parsing if a commit or tag contains an
embedded NUL).
Let's drop these extra "sz" parameters, as they are misleading about how
the functions intend to access the buffer. We can drop from both the

While in general the 'git ls-remote' command can be run outside of a

require access to the referenced objects. This sorting is implemented
using the generic ref-filter sorting facility, which already handles
missing objects gracefully with the appropriate 'missing object
deadbeef for HEAD' message. However, being generic means that it
checks replace refs while trying to retrieve an object, and while
doing so it accesses the 'git_replace_ref_base' variable, which has
not been initialized and is still a NULL pointer when outside of a
repository, thus causing the segfault.
Make ref-filter more careful upfront while parsing the format string,
and make it error out when encountering a format atom requiring object
access when we are not in a repository. Also add a test to ensure
that 'git ls-remote --sort' fails gracefully when executed outside of

Introduce optname() that does the early half of original opterror() to
come up with the name of the option reported back to the user, and use
it to kill opterror(). The callers of opterror() now directly call
error() using the string returned by opterror() instead.
There are a few issues with opterror()
- it tries to assemble an English sentence from pieces. This is not
great for translators because we give them pieces instead of a full
sentence.
- It's a wrapper around error() and needs some hack to let the
compiler know it always returns -1.
- Since it takes a string instead of printf format, one call site has
to assemble the string manually before passing to it.
Using error() directly solves the second and third problems.
It kind helps the first problem as well because "%s does foo" does
give a translator a full sentence in a sense and let them reorder if
needed. But it has limitations, if the subject part has to change
based on the rest of the sentence, that language is screwed. This is
also why I try to avoid calling optname() when 'flags' is known in
advance.

When we define a parse-options callback, the flags we put in the option
struct must match what the callback expects. For example, a callback
which does not handle the "unset" parameter should only be used with
PARSE_OPT_NONEG. But since the callback and the option struct are not
defined next to each other, it's easy to get this wrong (as earlier
patches in this series show).
Fortunately, the compiler can help us here: compiling with
-Wunused-parameters can show us which callbacks ignore their "unset"
parameters (and likewise, ones that ignore "arg" expect to be triggered
with PARSE_OPT_NOARG).
But after we've inspected a callback and determined that all of its
callers use the right flags, what do we do next? We'd like to silence
the compiler warning, but do so in a way that will catch any wrong calls
in the future.
We can do that by actually checking those variables and asserting that
they match our expectations. Because this is such a common pattern,
we'll introduce some helper macros. The resulting messages aren't
as descriptive as we could make them, but the file/line information from
BUG() is enough to identify the problem (and anyway, the point is that
these should never be seen).
Each of the annotated callbacks in this patch triggers
-Wunused-parameters, and was manually inspected to make sure all callers
use the correct options (so none of these BUGs should be triggerable).

Plugging a handful of memory leaks in the ref-filter codepath.
* ot/ref-filter-plug-leaks:
ref-filter: free item->value and item->value->s
ls-remote: release memory instead of UNLEAK
ref-filter: free memory from used_atom
Various codepaths in the core-ish part learn to work on an
arbitrary in-core index structure, not necessarily the default
instance "the_index".
* nd/the-index: (23 commits)
revision.c: reduce implicit dependency the_repository

Release item->value.
Initialize item->value->s dynamically and then release its resources.
Release some local variables.
Final goal of this patch is to reduce number of memory leaks.
