The helper functions (strbuf_branchname, strbuf_check_branch_ref,
and strbuf_check_tag_ref) are about handling branch and tag names,
and it is a non-essential fact that these functions use strbuf to
hold these names. Rename them to make it clarify that these are
more about "ref".

strbuf_branchname(), strbuf_check_{branch,tag}_ref() are helper
functions to deal with branch and tag names, and the fact that they
happen to use strbuf to hold the name of a branch or a tag is not
essential. These functions fit better in the refs API than strbuf
API, the latter of which is about string manipulations.

Instead of including USE_THE_REPOSITORY_VARIABLE by default on every
builtin, remove it from builtin.h and add it to all the builtins that
include builtin.h (by definition, that means all builtins/*.c).
Also, remove the include statement for repository.h since it gets

After using the ref-filter API, callers should use ref_filter_clear() to
free any used memory. However, there's not a matching function to clear
the ref_format struct.
Traditionally this did not need to be cleaned up, as it was just a way
for the caller to store and pass format options as a single unit. Even
though the parsing step of some placeholders may allocate data, that's
usually inside their "used_atom" structs, which are part of the
ref_filter itself.
But a few placeholders keep data outside of there. The %(ahead-behind)
and %(is-base) parsers both keep a master list of bases, because they
perform a single filtering pass outside of the use of any particular
atom. And since the format parser does not have access to the ref_filter
struct, they store their cross-atom data in the ref_format struct
itself.
And thus when they are finished, the ref_format also needs to be cleaned
up. So let's add a function to do so, and call it from all of the users
of the ref-filter API.
The %(is-base) case is found by running LSan on t6300. After this patch,
the script can now be marked leak-free.

git-tag supports interpreting trailers from an annotated tag message,
using --list --format="%(trailers)". However, the available methods to
add a trailer to a tag message (namely -F or --editor) are not as
ergonomic.
In a previous patch, we moved git-commit's implementation of its
--trailer option to the trailer.h API. Let's use that new function to
teach git-tag the same --trailer option, emulating as much of
git-commit's behavior as much as possible.

The function `ref_transaction_update()` obtains ref information and
flags to create a `ref_update` and add them to the transaction at hand.
To extend symref support in transactions, we need to also accept the
old and new ref targets and process it. This commit adds the required
parameters to the function and modifies all call sites.
The two parameters added are `new_target` and `old_target`. The
`new_target` is used to denote what the reference should point to when
the transaction is applied. Some functions allow this parameter to be
NULL, meaning that the reference is not changed.
The `old_target` denotes the value the reference must have before the
update. Some functions allow this parameter to be NULL, meaning that the
old value of the reference is not checked.
We also update the internal function `ref_transaction_add_update()`
similarly to take the two new parameters.

As part of our transition to multi-byte comment characters, we should
use the string variable rather than the historical character variable.
All of the sites adjusted here are just swapping out "%c" for "%s" in
format strings, or strbuf_addch() for strbuf_addstr(). The type system
and printf-attribute give the compiler enough information to make sure
our formats and variable changes all match (especially important for
cases where the format string is defined far away from its use, like
prepare_to_commit() in commit.c).

As part of our transition to multi-byte comment characters, let's take a
NUL-terminated string pointer for strbuf_commented_addf() rather than a
single character.
All of the callers have to be adjusted, but they can just pass
comment_line_str rather than comment_line_char.
Note that we rely on strbuf_add_commented_lines() under the hood, so
we'll cheat a bit to squeeze our string into a single character (for now
the two are equivalent, and we'll address this TODO in the next patch).

As part of our transition to multi-byte comment characters, let's take a
NUL-terminated string pointer for strbuf_stripspace(), rather than a
single character. We can continue to support its feature of ignoring
comments by accepting a NULL pointer (as opposed to the current behavior
of a NUL byte).
All of the callers have to be adjusted, but they can all just pass
comment_line_str (or NULL).
Inside the function we detect comments by comparing the first byte of a
line to the comment character. We'll adjust that to use starts_with(),
which will match multiple bytes (though for now, of course, we still
only allow a single byte, so it's academic).

A failed "git tag -s" did not necessarily result in an error
depending on the crypto backend, which has been corrected.
* jc/sign-buffer-failure-propagation-fix:
ssh signing: signal an error with a negative return value
tag: fix sign_buffer() call to create a signed tag
|
|
The command "git tag -s" internally calls sign_buffer() to make a
cryptographic signature using the chosen backend like GPG and SSH.
The internal helper functions used by "git tag" implementation seem
to use a "negative return values are errors, zero or positive return
values are not" convention, and there are places (e.g., verify_tag()
that calls gpg_verify_tag()) that these internal helper functions
translate return values that signal errors to conform to this
convention, but do_sign() that calls sign_buffer() forgets to do so.
Fix it, so that a failed call to sign_buffer() that can return the
exit status from pipe_command() will not be overlooked.

Add two new public methods to 'ref-filter.h':
* 'print_formatted_ref_array()' which, given a format specification & array
of ref items, formats and prints the items to stdout.
* 'filter_and_format_refs()' which combines 'filter_refs()',
'ref_array_sort()', and 'print_formatted_ref_array()' into a single
function.
This consolidates much of the code used to filter and format refs in
'builtin/for-each-ref.c', 'builtin/tag.c', and 'builtin/branch.c', reducing
duplication and simplifying the future changes needed to optimize the filter

'max_count' and 'omit_empty'. These values are specified by the '--count'

When '--no-sort' is passed to 'for-each-ref', 'tag', and 'branch', the
printed refs are still sorted by ascending refname. Change the handling of
sort options in these commands so that '--no-sort' to truly disables
sorting.
'--no-sort' does not disable sorting in these commands is because their
option parsing does not distinguish between "the absence of '--sort'"
(and/or values for tag.sort & branch.sort) and '--no-sort'. Both result in
an empty 'sorting_options' string list, which is parsed by
'ref_sorting_options()' to create the 'struct ref_sorting *' for the
command. If the string list is empty, 'ref_sorting_options()' interprets
that as "the absence of '--sort'" and returns the default ref sorting
structure (equivalent to "refname" sort).
To handle '--no-sort' properly while preserving the "refname" sort in the
"absence of --sort'" case, first explicitly add "refname" to the string list
*before* parsing options. This alone doesn't actually change any behavior,
since 'compare_refs()' already falls back on comparing refnames if two refs
are equal w.r.t all other sort keys.
Now that the string list is populated by default, '--no-sort' is the only
way to empty the 'sorting_options' string list. Update
'ref_sorting_options()' to return a NULL 'struct ref_sorting *' if the
string list is empty, and add a condition to 'ref_array_sort()' to skip the
sort altogether if the sort structure is NULL. Note that other functions
using 'struct ref_sorting *' do not need any changes because they already
ignore NULL values.
Finally, remove the condition around sorting in 'ls-remote', since it's no
longer necessary. Unlike 'for-each-ref' et. al., it does *not* do any
sorting by default. This default is preserved by simply leaving its sort key
string list empty before parsing options; if no additional sort keys are
set, 'struct ref_sorting *' is NULL and sorting is skipped.

When we write a tag the object oid is specific to the hash algorithm.
This matters when a tag is signed. The hash transition plan calls for
signatures on both the sha1 form and the sha256 form of the object,
and for both of those signatures to live in the tag object.
To generate tag object with multiple signatures, first compute the
unsigned form of the tag, and then if the tag is being signed compute
the unsigned form of the tag with the compatibilityr hash. Then
compute compute the signatures of both buffers.
Once the signatures are computed add them to both buffers. This
allows computing the compatibility hash in do_sign, saving
write_object_file the expense of recomputing the compatibility tag
just to compute it's hash.

In the meantime, ensure that the `ref_filter` struct used in the

Add a new "const struct config_context *ctx" arg to config_fn_t to hold
additional information about the config iteration operation.
config_context has a "struct key_value_info kvi" member that holds
metadata about the config source being read (e.g. what kind of config
source it is, the filename, etc). In this series, we're only interested
in .kvi, so we could have just used "struct key_value_info" as an arg,
but config_context makes it possible to add/adjust members in the future
without changing the config_fn_t signature. We could also consider other
ways of organizing the args (e.g. moving the config name and value into
config_context or key_value_info), but in my experiments, the
incremental benefit doesn't justify the added complexity (e.g. a
config_fn_t will sometimes invoke another config_fn_t but with a
different config value).
In subsequent commits, the .kvi member will replace the global "struct
config_reader" in config.c, making config iteration a global-free
operation. It requires much more work for the machinery to provide
meaningful values of .kvi, so for now, merely change the signature and
call sites, pass NULL as a placeholder value, and don't rely on the arg
in any meaningful way.
Most of the changes are performed by
contrib/coccinelle/config_fn_ctx.pending.cocci, which, for every
config_fn_t:
- Modifies the signature to accept "const struct config_context *ctx"
- Passes "ctx" to any inner config_fn_t, if needed
- Adds UNUSED attributes to "ctx", if needed
Most config_fn_t instances are easily identified by seeing if they are
called by the various config functions. Most of the remaining ones are
manually named in the .cocci patch. Manual cleanups are still needed,
but the majority of it is trivial; it's either adjusting config_fn_t
that the .cocci patch didn't catch, or adding forward declarations of
"struct config_context ctx" to make the signatures make sense.
The non-trivial changes are in cases where we are invoking a config_fn_t
outside of config machinery, and we now need to decide what value of
"ctx" to pass. These cases are:
- trace2/tr2_cfg.c:tr2_cfg_set_fl()
This is indirectly called by git_config_set() so that the trace2
machinery can notice the new config values and update its settings
using the tr2 config parsing function, i.e. tr2_cfg_cb().
- builtin/checkout.c:checkout_main()
This calls git_xmerge_config() as a shorthand for parsing a CLI arg.
This might be worth refactoring away in the future, since
git_xmerge_config() can call git_default_config(), which can do much
more than just parsing.
Handle them by creating a KVI_INIT macro that initializes "struct
key_value_info" to a reasonable default, and use that to construct the
"ctx" arg.

git_color_default_config() is a shorthand for calling two other config
callbacks. There are no other non-static functions that do this and it
will complicate our refactoring of config_fn_t so inline it instead.

The vast majority of files including object-store.h did not need dir.h
nor khash.h. Split the header into two files, and let most just depend
upon object-store-ll.h, while letting the two callers that need it
depend on the full object-store.h.
After this patch:
$ git grep -h include..object-store | sort | uniq -c
2 #include "object-store.h"
129 #include "object-store-ll.h"
Diff best viewed with `--color-moved`.

This also made it clear that several .c files that depended upon path.h
were missing a #include for it; add the missing includes while at it.

Since this header showed up in some places besides just #include
statements, update/clean-up/remove those other places as well.
Note that compat/fsmonitor/fsm-path-utils-darwin.c previously got
away with violating the rule that all files must start with an include
of git-compat-util.h (or a short-list of alternate headers that happen
to include it first). This change exposed the violation and caused it
to stop building correctly; fix it by having it include
git-compat-util.h first, as per policy.

As a library that only interacts with other primitives, strbuf should
not utilize the comment_line_char global variable within its
functions. Therefore, add an additional parameter for functions that use
comment_line_char and refactor callers to pass it in instead.
strbuf_stripspace() removes the skip_comments boolean and checks if
comment_line_char is a non-NUL character to determine whether to skip
comments or not.

The ref transaction can fail after the user has written their tag
message. In particular, if there exists a tag `foo/bar` and `git tag -a
foo` is said then the command will only fail once it tries to write
`refs/tags/foo`, which is after the file has been unlinked.
Hold on to the message file for a little longer so that it is not
unlinked before the fatal error occurs.
