This is the tenth in a series of patches to convert from unsigned char
[20] to struct object_id. This series mostly involves changes to the
refs code. After these changes, there are almost no references to
unsigned char in the main refs code.
In this iteration, I chose to skip the ALLOC_ARRAY conversion to limit
the scope of changes and because I think to be fixed properly the code
requires converting the targets parameter to size_t, which involves
touching more code unrelated to the series than I'd like to do right
now.
All the other issues that were brought up should be fixed.
This series is available from the following URL:
https://github.com/bk2204/git.git object-id-part10
Changes from v2:
* Rebase on master. This drops significant parts of one patch, as Junio
pointed out.
* Restore sane line wrappings.
* Fix several docstrings and error messages to reflect object ID instead
of SHA-1.
* Fix potential NULL dereference in refs_delete_ref.
* Fix potential NULL dereference in expand_ref.
* Add a patch to fix potential NULL dereference in write_pseudoref.
* Restore the missing line in the refs code.
* Fix two commit message typos.
Changes from v1:
* Fix line wrapping in several places.
* Remove empty line.
* Update die messages to refer to "object ID" instead of "sha1".

Convert delete_ref and refs_delete_ref to take a pointer to struct
object_id. Update the documentation accordingly, including referring to
null_oid in lowercase, as it is not a #define constant.

object_id. Update the existing callers as well. Remove update_ref_oid,
as it is no longer needed.

Several of the refs functions take NULL to indicate that the ref is not
to be updated. If refs_update_ref were called with a NULL new object
ID, we could pass that NULL pointer to write_pseudoref, which would then
segfault when it dereferenced it. Instead, simply return successfully,
since if we don't want to update the pseudoref, there's nothing to do.

Update the ref transaction code to use struct object_id. Remove one
NULL pointer check which was previously inserted around a dereference;
since we now pass a pointer to struct object_id directly through, the
code we're calling handles this for us.

All of the callers already pass the hash member of struct object_id, so
update them to pass a pointer to the struct directly,
This transformation was done with an update to declaration and
definition and the following semantic patch:

All but two of the call sites already have parameters using the hash
parameter of struct object_id, so convert them to take a pointer to the
struct directly. Also convert refs_read_refs_full, the underlying
implementation.

All of the callers of these functions just pass the hash member of a
struct object_id, so convert them to use a pointer to struct object_id
directly. Insert a check for NULL in expand_ref on a temporary basis;
this check can be removed when resolve_ref_unsafe is converted as well.

This transformation was done with an update to the declaration,
definition, comments, and test helper and the following semantic patch:

reflog_expire already used struct object_id internally, but it did not
take it as a parameter. Adjust the parameter (and the callers) to pass
a pointer to struct object_id instead of a pointer to unsigned char.
Remove the temporary inserted earlier as it is no longer required.

Convert these two functions and the functions that underlie them to take
pointers to struct object_id. This is a prerequisite to convert
resolve_gitlink_ref. Fix a stray tab in the middle of the index_mem
call in index_pipe by converting it to a space.

Convert the unsigned char * parameter to struct object_id * for
files_read_raw_ref and packed_read_raw_ref. Update the documentation.
Switch from using get_sha1_hex and a hard-coded 40 to using
parse_oid_hex.

Convert several static functions to take pointers to struct object_id.
Change the relevant parameters to write_packed_entry to be const, as we
don't modify them. Rename lock_ref_sha1_basic to lock_ref_oid_basic to
reflect its new argument. Update the docstring for verify lock to
account for the new parameter name, and note additionally that the
old_oid may be NULL.

With a hope that this might help other reviewers, here is the
interdiff between "the previous one merged with v2.15-rc1" and "this
round applied on v2.15-rc1 directly".
The changes all looked sensible to me. Thanks.

Is there a reasonably straightforward tool or workflow to generate
interdiffs? If so, I can include them in the future.

To me, it was straightforward to do:
$ git checkout master^0
$ git merge bc/object-id
... free conflict resolution thanks to rerere ...
$ git commit -a -m 'old one'
$ OLD=$(git describe)
$ git checkout master^0
$ git am bc-object-id.mbox
$ git diff $OLD
If you had a copy of my 'pu' branch, then you would have had a merge
commit that merges your previous version of the topic to it, and you
can feed that to contrib/rerere-train.sh to tell your rerere database
how I resolved the conflicts there, which may apply to the reproduction
of the above procedure yourself.
