diff.c: remove implicit dependency on the_index

2018-09-21T16:48:10Z

A new variant repo_diff_setup() is added that takes 'struct repository *' and diff_setup() becomes a thin macro around it that is protected by NO_THE_REPOSITORY_COMPATIBILITY_MACROS, similar to NO_THE_INDEX_.... The plan is these macros will always be defined for all library files and the macros are only accessible in builtin/ Signed-off-by: Nguyễn Thái Ngọc Duy Signed-off-by: Junio C Hamano

convert "oidcmp() != 0" to "!oideq()"

2018-08-29T18:32:49Z

This is the flip side of the previous two patches: checking for a non-zero oidcmp() can be more strictly expressed as inequality. Like those patches, we write "!= 0" in the coccinelle transformation, which covers by isomorphism the more common: if (oidcmp(E1, E2)) As with the previous two patches, this patch can be achieved almost entirely by running "make coccicheck"; the only differences are manual line-wrap fixes to match the original code. There is one thing to note for anybody replicating this, though: coccinelle 1.0.4 seems to miss the case in builtin/tag.c, even though it's basically the same as all the others. Running with 1.0.7 does catch this, so presumably it's just a coccinelle bug that was fixed in the interim. Signed-off-by: Jeff King Signed-off-by: Junio C Hamano

refactor various if (x) FREE_AND_NULL(x) to just FREE_AND_NULL(x)

2018-08-17T17:08:56Z

Change the few conditional uses of FREE_AND_NULL(x) to be unconditional. As noted in the standard[1] free(NULL) is perfectly valid, so we might as well leave this check up to the C library. 1. http://pubs.opengroup.org/onlinepubs/9699919799/functions/free.html Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano

diff: make struct diff_flags members lowercase

2017-11-01T02:51:40Z

Now that the flags stored in struct diff_flags are being accessed directly and not through macros, change all struct members from being uppercase to lowercase.

tree-walk: convert fill_tree_descriptor() to object_id

2017-08-14T19:38:54Z

All callers of fill_tree_descriptor() have been converted to object_id already, so convert that function as well. As a nice side-effect we get rid of NULL checks in tree-diff.c, as fill_tree_descriptor() already does them for us.
