A sister series to the just-submitted series of trivial designated
initalizer cleanups:
https://lore.kernel.org/git/cover-0.5-00000000000-20210927T003330Z-avarab@gmail.com/
This doesn't conflict semantically or textually with that series, but
is migrating to easier to manage initialization patterns for the same
reasons.
The code changes are all rather small, the diff in 6/6 looks scary,
but as --word-diff will show most of it schanging x->y to an &x->y and
the like, as two struct members were changed from being pointers.
Ævar Arnfjörð Bjarmason (6):
daemon.c: refactor hostinfo_init() to HOSTINFO_INIT macro
builtin/blame.c: refactor commit_info_init() to COMMIT_INFO_INIT macro
shortlog: use designated initializer for "struct shortlog"

Remove the hostinfo_init() function added in 01cec54e135 (daemon:
deglobalize hostname information, 2015-03-07) and instead initialize
the "struct hostinfo" with a macro.
This is the more idiomatic pattern in the codebase, and doesn't leave
us wondering when we see the *_init() function if this struct needs
more complex initialization than a macro can provide.

Remove the commit_info_init() function addded in ea02ffa3857 (mailmap:
simplify map_user() interface, 2013-01-05) and instead initialize the
"struct commit_info" with a macro.
This is the more idiomatic pattern in the codebase, and doesn't leave
us wondering when we see the *_init() function if this struct needs
more complex initialization than a macro can provide.
The get_commit_info() function is only called by the three callers
being changed here immediately after initializing the struct with the
macros, so by moving the initialization to the callers we don't need
to do it in get_commit_info() anymore.

option variables static, 2016-06-13) to use a designated initializer

Use a new REF_STATES_INIT designated initializer instead of assigning
to the "strdup_strings" member of the previously memzero()'d version
of this struct.
The pattern of assigning to "strdup_strings" dates back to
211c89682ee (Make git-remote a builtin, 2008-02-29) (when it was
"strdup_paths"), i.e. long before we used anything like our current
established *_INIT patterns consistently.
Then in e61e0cc6b70 (builtin-remote: teach show to display remote
HEAD, 2009-02-25) and e5dcbfd9ab7 (builtin-remote: new show output
style for push refspecs, 2009-02-25) we added some more of these.
As it turns out we only initialized this struct three times, all the
other uses were of pointers to those initialized structs. So let's
initialize it in those three places, skip the memset(), and pass those
structs down appropriately.

In the preceding commit we introduced REF_STATES_INIT, but did not
change the "struct show_info" to have a corresponding
initializer. Let's do that, and make it use "REF_STATES_INIT" and
"STRING_LIST_INIT_DUP", doing that requires changing "list" and
"states" away from being pointers.
The resulting end-state is simpler since we omit the local "info_list"
and "states" variables in show() as well as the memset().

looking at this wouldn't it be better follow the pattern in the first
patch in this series and replace shortlog_init() with a designated
initializer?

I've ejected this patch from a WIP re-roll, I don't know what I was
thinking when I included it.
It's "correct", but one of those cases where we can't easily get rid of
the not-a-macro init() function, so having a *_INIT macro that doesn't
actually do the initialization for both users is just confusing.
Worse, that "nodup" is actually a like, the shortlog_init() function
sets it to "dup", that issue pre-dated by change here, but I shouldn't
have carried it forward.
Sorry!

http://lore.kernel.org/git/87lf3i1e7k.fsf@evledraar.gmail.com I
ejected the previous 3/6. It wasn't incorrect, but partially
converting to an *_INIT macro doesn't make any sense in the "struct

Remove the hostinfo_init() function added in 01cec54e135 (daemon:
deglobalize hostname information, 2015-03-07) and instead initialize
the "struct hostinfo" with a macro.
This is the more idiomatic pattern in the codebase, and doesn't leave
us wondering when we see the *_init() function if this struct needs
more complex initialization than a macro can provide.

Remove the commit_info_init() function addded in ea02ffa3857 (mailmap:
simplify map_user() interface, 2013-01-05) and instead initialize the
"struct commit_info" with a macro.
This is the more idiomatic pattern in the codebase, and doesn't leave
us wondering when we see the *_init() function if this struct needs
more complex initialization than a macro can provide.
The get_commit_info() function is only called by the three callers
being changed here immediately after initializing the struct with the
macros, so by moving the initialization to the callers we don't need
to do it in get_commit_info() anymore.

Change the initialization pattern of "struct urlmatch_config" to use
an *_INIT macro and designated initializers.

Use a new REF_STATES_INIT designated initializer instead of assigning
to the "strdup_strings" member of the previously memzero()'d version
of this struct.
The pattern of assigning to "strdup_strings" dates back to
211c89682ee (Make git-remote a builtin, 2008-02-29) (when it was
"strdup_paths"), i.e. long before we used anything like our current
established *_INIT patterns consistently.
Then in e61e0cc6b70 (builtin-remote: teach show to display remote
HEAD, 2009-02-25) and e5dcbfd9ab7 (builtin-remote: new show output
style for push refspecs, 2009-02-25) we added some more of these.
As it turns out we only initialized this struct three times, all the
other uses were of pointers to those initialized structs. So let's
initialize it in those three places, skip the memset(), and pass those
structs down appropriately.

In the preceding commit we introduced REF_STATES_INIT, but did not
change the "struct show_info" to have a corresponding
initializer. Let's do that, and make it use "REF_STATES_INIT" and
"STRING_LIST_INIT_DUP", doing that requires changing "list" and
"states" away from being pointers.
The resulting end-state is simpler since we omit the local "info_list"
and "states" variables in show() as well as the memset().

While I think this is much easier to follow than the original, I am
not quite sure about the removal of these explicit _assignments_ in
code, like this ...
> config.collect_fn = urlmatch_collect_fn;
> - config.cascade_fn = NULL;
> config.cb = &values;
and this ...

as they have documentation value (e.g. "for this invocation I do
want to use no cascade_fn" is a statement worth making, by having
it next to the assignment to .collect_fn member).

... we used to set up selectively to own.
How would we make sure after this change we are not adding leaks?
Is there a way to do so mechanically?

Like this one, get_remote_ref_states() used to receive states that
are set to borrow strings, but now we get duplicated strings, right?
Are we leaking whatever strings we push to these string lists now?

I manual run with SANITIZE=leak shows the same amount of memory leakage
before & after this change for me.
We should fix those leaks, but until my "tests: add a test mode for
SANITIZE=leak, run it in CI" lands on master I'm still waiting on fixing
those, and this series will help make it easier.
The ownership of the "states" struct or its lifetime isn't different
after this change. It's only that we're doing:
struct foo = FOO_INIT;
/* use &foo */
Instead of:
struct foo;
memset(&foo, 0, sizeof(foo));
foo->some_list.strdup_strings = 1;
What is different is that that "strdup_strings" member in the contained
"some_list" will be set to "1" earlier. E.g. in the case of this in the
pre-image:
states->new_refs.strdup_strings = 1;
We'd do that in get_ref_states(), which was called by
get_remote_ref_states(), which was e.g. called by show(). So before we
wouldn't flip that particular value until we got all the way down into
get_remote_ref_states(), now we initialize the struct like that on the
stack right away.
But it doesn't result in any new allocations, string_list like strbuf
etc. won't allocate until something is pushed onto the list, using the
common "nr/alloc" & malloc on demand pattern.

Ah, yes it *could* happen as a side-effect of this sotr of change that
that memset() was implicitly flipping some string_list structs to the
equivalent of strdup_strings=0.
But that's not the case here, it was just memset() boilerplate, then in
get_remote_ref_states() we'd set all the string lists we'd use to "dup".

No, I am not talking about ownership of "foo" itself. What changes
is ownership of some of the string_list embedded in "foo" that used
NOT to have strdup_strings member set now have the bit set, so the
string list owns the string.

OK, get_remotes_ref_states() marked all string list to the dup
variant, then we won't have a problem. I was trying to make sure
that was something you looked at when preparing these patches.

for the v2.
This v3:
* Addresses Junio's comments about URLMATCH_CONFIG_INIT use, I'm no
longer removing explicit assignments to NULL related to it.
* Updates the commit message of 5/6 for the discussion ending at
https://lore.kernel.org/git/xmqqv92lmv2b.fsf@gitster.g/
* I've added a new 6/6 with an UNPACK_TREES_OPTIONS_INIT. It's
related to the discussion about how unpack-trees.[ch] memory
management happens at [1], but is really orthagonal to the points
Elijah and I were discussing there.
I think whatever approach we'd decide to go with (his in
en/removing-untracked-fixes, or my WIP suggestion) the move to an
UNPACK_TREES_OPTIONS_INIT makes sense, and would be the same either
way.
It does make the WIP patches I've got at[1] to solve memory leaks &
simplify the setup in unpack-trees.[ch] much smaller, and is like
the other *_INIT changes here, so I've included it.

Remove the hostinfo_init() function added in 01cec54e135 (daemon:
deglobalize hostname information, 2015-03-07) and instead initialize
the "struct hostinfo" with a macro.
This is the more idiomatic pattern in the codebase, and doesn't leave
us wondering when we see the *_init() function if this struct needs
more complex initialization than a macro can provide.

Remove the commit_info_init() function addded in ea02ffa3857 (mailmap:
simplify map_user() interface, 2013-01-05) and instead initialize the
"struct commit_info" with a macro.
This is the more idiomatic pattern in the codebase, and doesn't leave
us wondering when we see the *_init() function if this struct needs
more complex initialization than a macro can provide.
The get_commit_info() function is only called by the three callers
being changed here immediately after initializing the struct with the
macros, so by moving the initialization to the callers we don't need
to do it in get_commit_info() anymore.

Use a new REF_STATES_INIT designated initializer instead of assigning
to the "strdup_strings" member of the previously memzero()'d version
of this struct.
The pattern of assigning to "strdup_strings" dates back to
211c89682ee (Make git-remote a builtin, 2008-02-29) (when it was
"strdup_paths"), i.e. long before we used anything like our current
established *_INIT patterns consistently.
Then in e61e0cc6b70 (builtin-remote: teach show to display remote
HEAD, 2009-02-25) and e5dcbfd9ab7 (builtin-remote: new show output
style for push refspecs, 2009-02-25) we added some more of these.
As it turns out we only initialized this struct three times, all the
other uses were of pointers to those initialized structs. So let's
initialize it in those three places, skip the memset(), and pass those
structs down appropriately.
This would be a behavior change if we had codepaths that relied say on
implicitly having had "new_refs" initialized to STRING_LIST_INIT_NODUP
with the memset(), but only set the "strdup_strings" on some other
struct, but then called string_list_append() on "new_refs". There
isn't any such codepath, all of the late assignments to
"strdup_strings" assigned to those structs that we'd use for those
codepaths.
So just initializing them all up-front makes for easier to understand
code, i.e. in the pre-image it looked as though we had that tricky
edge case, but we didn't.

In the preceding commit we introduced REF_STATES_INIT, but did not
change the "struct show_info" to have a corresponding
initializer. Let's do that, and make it use "REF_STATES_INIT" and
"STRING_LIST_INIT_DUP", doing that requires changing "list" and
"states" away from being pointers.
The resulting end-state is simpler since we omit the local "info_list"
and "states" variables in show() as well as the memset().

Almost all users of "struct unpack_trees_options" allocate it on the
stack already, let's provide an *_INIT macro for them to use. This
will make later changes that would like to initialize other members of
the struct easier[1][2], but for now we're keeping it compatible with
a memset() to "0" with an "{ 0 }" initialization.
This leaves a caller in "checkout_fast_forward()" in "merge.c" still
doing the memset(). I've left it to avoid a conflict with the
in-flight en/removing-untracked-fixes. As noted above conflict is just
textual, not semantic, so we can clean it up some other time. I've
manually validated[3] with some WIP changes on top of this that the
remaining "checkout_fast_forward()" caller is the only one that.s
left.

These two hunks almost makes me say "Meh" (I am adding this
parenthetical comment after reading the patch thru and I am not yet
convinced otherwise).
The reason why we had memset(0), getting rid of which I have no
problem about, is because we didn't prepare the members of the
structure using initializer in the first place, no? The "opts" is
used only in this block, so instead of these lines, we could have
if (!args->worktree_attributes) {
struct unpack_trees_options opts = {
.index_only = 1,
.head_idx = -1,
...
.fn = oneway_merge;
};
init_tree_desc(...);
if (unpack_trees(1, &t, &opts))
...
which would be much easier to understand. We can get rid of
memset(0), having UNPACK_TREES_OPTIONS_INIT did not help us much.
Some hunks show that we have code between the location where "opts"
is declared and where we know for certain that "opts" needs to be
actually used and with what values in its members, like ...

... this one. And it is not necessarily a good idea to initialize
"opts" with the actual values we'd use, and _INIT does help us
getting rid of memset(0);
But many in this patch are much simpler like this one:

which can be initialized with designated initializers in place, and
having an _INIT macro would not help us very much.

I ejected teh "UNPACK_TREES_OPTIONS_INIT" patch. I'll just propose
that as some alternate/fixup for en/removing-untracked-fixes

Remove the hostinfo_init() function added in 01cec54e135 (daemon:
deglobalize hostname information, 2015-03-07) and instead initialize
the "struct hostinfo" with a macro.
This is the more idiomatic pattern in the codebase, and doesn't leave
us wondering when we see the *_init() function if this struct needs
more complex initialization than a macro can provide.

Remove the commit_info_init() function addded in ea02ffa3857 (mailmap:
simplify map_user() interface, 2013-01-05) and instead initialize the
"struct commit_info" with a macro.
This is the more idiomatic pattern in the codebase, and doesn't leave
us wondering when we see the *_init() function if this struct needs
more complex initialization than a macro can provide.
The get_commit_info() function is only called by the three callers
being changed here immediately after initializing the struct with the
macros, so by moving the initialization to the callers we don't need
to do it in get_commit_info() anymore.

Change the initialization pattern of "struct urlmatch_config" to use
an *_INIT macro and designated initializers. Right now there's no
other "struct" member of "struct urlmatch_config" which would require
its own *_INIT, but it's good practice not to assume that. Let's also
change this to a designated initializer while we're at it.

Use a new REF_STATES_INIT designated initializer instead of assigning
to the "strdup_strings" member of the previously memzero()'d version
of this struct.
The pattern of assigning to "strdup_strings" dates back to
211c89682ee (Make git-remote a builtin, 2008-02-29) (when it was
"strdup_paths"), i.e. long before we used anything like our current
established *_INIT patterns consistently.
Then in e61e0cc6b70 (builtin-remote: teach show to display remote
HEAD, 2009-02-25) and e5dcbfd9ab7 (builtin-remote: new show output
style for push refspecs, 2009-02-25) we added some more of these.
As it turns out we only initialized this struct three times, all the
other uses were of pointers to those initialized structs. So let's
initialize it in those three places, skip the memset(), and pass those
structs down appropriately.
This would be a behavior change if we had codepaths that relied say on
implicitly having had "new_refs" initialized to STRING_LIST_INIT_NODUP
with the memset(), but only set the "strdup_strings" on some other
struct, but then called string_list_append() on "new_refs". There
isn't any such codepath, all of the late assignments to
"strdup_strings" assigned to those structs that we'd use for those
codepaths.
So just initializing them all up-front makes for easier to understand
code, i.e. in the pre-image it looked as though we had that tricky
edge case, but we didn't.

In the preceding commit we introduced REF_STATES_INIT, but did not
change the "struct show_info" to have a corresponding
initializer. Let's do that, and make it use "REF_STATES_INIT" and
"STRING_LIST_INIT_DUP", doing that requires changing "list" and
"states" away from being pointers.
The resulting end-state is simpler since we omit the local "info_list"
and "states" variables in show() as well as the memset().
