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 hashmap comparison functions to oideq()

2018-08-29T18:32:49Z

The comparison functions used for hashmaps don't care about strict ordering; they only want to compare entries for equality. Let's use the oideq() function instead, which can potentially be better optimized. Note that unlike the previous patches mass-converting calls like "!oidcmp()", this patch could actually provide an improvement even with the current implementation. Those comparison functions are passed around as function pointers, so at compile-time the compiler cannot realize that the caller (which is in another file completely) will treat the return value as a boolean. Note that this does change the return values in quite a subtle way (it's still an int, but now the sign bit is irrelevant for ordering). Because of their funny hashmap-specific signature, it's unlikely that any of these static functions would be reused for more generic ordering. But to be double-sure, let's stop using "cmp" in their names. Calling them "eq" doesn't quite work either, because the hashmap convention is actually _inverted_. "0" means "same", and non-zero means "different". So I've called them "neq" by convention here. Signed-off-by: Jeff King 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.

patch-ids.c: use hashmap correctly

2017-06-30T20:11:54Z

As alluded to in the previous patch, the code in patch-ids.c is using the hashmaps API wrong. Luckily we do not have a bug, as all hashmap functionality that we use here (hashmap_get) passes through the keydata. If hashmap_get_next were to be used, a bug would occur as that passes NULL for the key_data. So instead use the hashmap API correctly and provide the caller required data in the compare function via the first argument that always gets passed and was setup via the hashmap_init function.

hashmap.h: compare function has access to a data field

2017-06-30T19:49:28Z

When using the hashmap a common need is to have access to caller provided data in the compare function. A couple of times we abuse the keydata field to pass in the data needed. This happens for example in patch-ids.c. This patch changes the function signature of the compare function to have one more void pointer available. The pointer given for each invocation of the compare function must be defined in the init function of the hashmap and is just passed through. Documentation of this new feature is deferred to a later patch. This is a rather mechanical conversion, just adding the new pass-through parameter. However while at it improve the naming of the fields of all compare functions used by hashmaps by ensuring unused parameters are prefixed with 'unused_' and naming the parameters what they are (instead of 'unused' make it 'unused_keydata').
