The mv builtin uses the compatibility macros to interact with the index.
Update these to use modern methods referring to a 'struct index_state'
pointer. Several helper methods need to be updated to consider such a
pointer, but the modifications are rudimentary.
Two macros can be deleted from cache.h because these are the last uses.

The rm builtin still uses the antiquated compatibility macros for
interacting with the index. Update these to the more modern uses by
passing around a 'struct index_state' pointer.

To reduce the need for the index compatibility macros, we will replace
their uses in update-index mechanically. This is the most interesting
change, which creates global "repo" and "istate" pointers. The macros
that expand to use the_index can then be mechanically replaced by
references to the istate pointer.

From: Derrick Stolee <dstolee@microsoft.com>
The final index compatibility macro to remove from the update-index
builtin is ce_match_stat(). Further, this is the last use of that macro
anywhere, so it should be removed.
There are some remaining references in the racy-git.txt technical
document that are updated to ie_match_stat().

In order to remove index compatibility macros cleanly, we relied upon
static globals 'repo' and 'istate' to be pointers to the_repository and
the_index, respectively. We can now start reducing the need for these
static globals by modifying method prototypes to use them when
necessary.
Move these static globals further down in the file so we can identify
which method only need to add a 'struct index_state *istate' parameter.
The only changes included here adjust method prototypes and their call
locations.

In order to remove index compatibility macros cleanly, we relied upon
static globals 'repo' and 'istate' to be pointers to the_repository and
the_index, respectively. We can continue reducing the need for these
static globals by modifying method prototypes to use them when
necessary.
Move these static globals further down the file so we can identify which
methods need both 'struct repository *repo' and 'struct index_state
*istate' parameters. The only changes included here adjust method
prototypes and their call locations.
The only remaining change is to remove the static globals entirely, but
that requires updating the parse-opt callbacks, which need a different
solution.

From: Derrick Stolee <dstolee@microsoft.com>
In order to remove index compatibility macros cleanly, we relied upon
static globals 'repo' and 'istate' to be pointers to the_repository and
the_index, respectively. We remove these static globals inside the
option parsing callbacks, which are the final uses in update-index.
The callbacks cannot change their method signature, so we must use the
value member of 'struct option', assigned in the array of option macros.
There are several callback methods that require at least one of 'repo'
and 'istate', but they use a variety of different data types for the
callback value.
Unify these callback methods to use a consistent 'struct callback_data'
that contains 'repo' and 'istate', ready to use. This takes the place of
the previous 'struct refresh_params' which served only to group the
'flags' and 'has_errors' ints. We also collect other one-off settings,
but only those that require access to the index or repository in their
operation.

Makes sense. The patch itself is necessarily a bit noisy, but there's
nothing particularly complicated in that noise.

The only mildly unexpected thing here is that `has_errors` is now a
simple value rather than a pointer to a value, but you handle that
easily enough by always accessing `has_error` directly from the
structure, even within the function in which `has_error` used to be a
local variable. Fine.

Will there ever be a case in which `cd.istate` will be different from
`cd.repo->index`? If not, then we could get by with having only
`cd.repo`; callers requiring access to `istate` can fetch it from
`cd.repo`. If, on the other hand, `cd.istate` can be different from
`cd.repo->istate` -- or if that might become a possibility in the
future -- then having `cd.istate` makes sense. Not a big deal, though.
Just generally curious about it.

I don't believe that 'istate' and 'repo->index' will ever be
different in this file. This includes the members of the
callback_data struct, but also the method parameters throughout.
Mostly, this could be seen as an artifact of how we got here:
1. References to the_index or other compatibility macros were
converted to use the static global 'istate'.
2. References to the static global 'istate' were replaced with
method parameters for everything except these callbacks.
3. These callbacks were updated to use 'cd.istate' instead of
the (now defunct) static global 'istate'.
It could be possible to replace all references to 'istate' with
'repo->index' but the patches get slightly more messy. I also
think the code looks messier, but you do make a good point that
there is no concrete reason to separate the two.
Thanks,

I agree that it would make the code a bit noisier (to read) if
`istate` is eliminated from the callback structure, however, even
though I didn't originally feel strongly one way or the other about
having both `repo` and `istate` in the structure, I'm now leaning more
toward seeing `istate` eliminated. My one (big) concern with `istate`
is that it confuses readers into wondering whether `istate` and
`repo->istate` will ever be different. One way to avoid such confusion
would be to leave a comment in the code stating that the two values
will always be the same. The other way, of course, is to eliminate
`istate` from the structure altogether. I don't want to make more work
for you, but the more I think about it, the more I feel that removing
`istate` is the sensible thing to do. (And it doesn't require an extra
patch -- it can just be how this patch is crafted -- without ever
introducing `istate` to the structure in the first place.)

Some applications may want to work on more than one in-core index at
the same time (perhaps a merge strategy may want to keep a copy of
the original index and update a second copy with the result of the
merge), and it may be useful for such applications if 'repo->istate'
does not have to be the in-core index instance to be worked on. So
things that go in libgit.a may want to allow such distinction.
But what goes in builtin/ is a different story. As long as this
application has no need for such a feature and will always work on
the primary in-core index, prepared for the in-core repository
structure for convenience, it may not worth it to support such a
feature that no callers benefit from.
Thanks.

I'll try to restructure my patches to do the following order:
1. replace compatibility macros with static global references, except
i. use 'istate' in the methods that don't need a repository.
ii. use 'repo->index' in the methods that need a repository.
2. replace static globals with method parameters.
i. drop 'istate' static global with method parameters. Methods that
have a repo will pass 'repo->index' to these methods.
ii. drop 'repo' static global with method parameters.
3. replace static globals in callback methods using 'repo->index',
where 'repo' is a member of the callback_data struct.
That should keep the structure as presented in v2 while also avoiding
this question of "can istate differ from repo->index?"
Thanks,

UPDATE: this is now based on ag/merge-strategies-in-c to avoid conflicts in
'seen'. The changes in builtin/rm.c still conflict with
mt/rm-sparse-checkout, but that branch seems to be waiting for a clearer
plan on some corner cases. I thought about ejecting it, but 'rm' still uses
ce_match_stat(), so just dropping the patch gives less of a final stake at
the end of the series. (I'm still open to it, if necessary.)
I noticed that Duy's project around USE_THE_INDEX_COMPATIBILITY_MACROS has
been on pause for a while. Here is my attempt to continue that project a
little.
I started going through the builtins that still use cache_name_pos() and the
first was easy: mv and rm.
Then I hit update-index and it was a bit bigger.
My strategy for update-index was to create static globals "repo" and
"istate" that point to the_repository and the_index, respectively. Then, I
was able to remove macros one-by-one without changing method prototypes
within the file. Then, these static globals were also removed by
systematically updating the local method prototypes, plus some fancy
structure stuff for the option parsing callbacks.
I had started trying to keep everything local to the method signatures, but
I hit a snag when reaching the command-line parsing callbacks, which I could
not modify their call signature. At that point, I had something that was
already much more complicated than what I present now. Outside of the first
update-index commit, everything was a mechanical find/replace.
In total, this allows us to remove four of the compatibility macros because
they are no longer used.
Updates in V3
=============
* Methods that know about the 'repo' pointer no longer also have an
'istate' pointer and instead prefer 'repo->index'
* This includes the callback_data struct which only has a 'repo' member, no
'istate'.

From: Derrick Stolee <dstolee@microsoft.com>
The mv builtin uses the compatibility macros to interact with the index.
Update these to use modern methods referring to a 'struct index_state'
pointer. Several helper methods need to be updated to consider such a
pointer, but the modifications are rudimentary.
Two macros can be deleted from cache.h because these are the last uses.

From: Derrick Stolee <dstolee@microsoft.com>
To reduce the need for the index compatibility macros, we will replace
their uses in update-index mechanically. This is the most interesting
change, which creates global "repo" and "istate" pointers. The macros
that expand to use the_index can then be mechanically replaced by
references to the istate pointer.
We will be careful to use "repo->index" over "istate" whenever repo is
needed by a method.

The final index compatibility macro to remove from the update-index
builtin is ce_match_stat(). Further, this is the last use of that macro
anywhere, so it should be removed.
There are some remaining references in the racy-git.txt technical
document that are updated to ie_match_stat().

In order to remove index compatibility macros cleanly, we relied upon
static globals 'repo' and 'istate' to be pointers to the_repository and
the_index, respectively. We can now start reducing the need for these
static globals by modifying method prototypes to use them when
necessary.
Remove the 'istate' static global in favor of method parameters. This
adjusts some callers, which either use their own 'istate' parameter or
'repo->index'.

In order to remove index compatibility macros cleanly, we relied upon
static globals 'repo' and 'istate' to be pointers to the_repository and
the_index, respectively. We can continue reducing the need for these
static globals by modifying method prototypes to use them when
necessary.
Move the remaining 'struct repository *repo' further down the file and
use method parameters to pass it around instead.
The only remaining change is to remove the static global entirely, but
that requires updating the parse-opt callbacks, which need a different
solution.

In order to remove index compatibility macros cleanly, we relied upon
static globals 'repo' and 'istate' to be pointers to the_repository and
the_index, respectively. We remove these static globals inside the
option parsing callbacks, which are the final uses in update-index.
The callbacks cannot change their method signature, so we must use the
value member of 'struct option', assigned in the array of option macros.
There are several callback methods that require at least one of 'repo'
and 'istate', but they use a variety of different data types for the
callback value.
Unify these callback methods to use a consistent 'struct callback_data'
that contains a 'repo' member, ready to use. This takes the place of
the previous 'struct refresh_params' which served only to group the
'flags' and 'has_errors' ints. We also collect other one-off settings,
but only those that require access to the index or repository in their
operation.

I haven't read this latest iteration myself yet beyond the cover
letter, but tonight's 'seen' has this queued near its tip. I expect
it would either stay there or occasionally ejected, until the base
topic solidifies a bit more.

OK.

I looked this version of the series over and did not find anything
else about which to comment.

Thanks. I'll continue to watch that topic and provide review as
new versions come out.

Junio,
Please drop this series for now. I'll be introducing a new series soon
that will collide with it and this is a lower priority.
I'll probably come back to revisit removing these macros, but I'll do
so one builtin at a time when others are not modifying them at the
same time.
Thanks,
-Stolee
