hashmap: convert sha1hash() to oidhash()

2019-06-20T17:44:22Z

There are no callers left of sha1hash() that do not simply pass the "hash" member of a "struct object_id". Let's get rid of the outdated sha1-specific function and provide one that operates on the whole struct (even though the technique, taking the first few bytes of the hash, will remain the same).

format-patch: make --base patch-id output stable

2019-05-08T10:27:43Z

We weren't flushing the context each time we processed a hunk in the patch-id generation code in diff.c, but we were doing that when we generated "stable" patch-ids with the 'patch-id' tool. Let's port that similar logic over from patch-id.c into diff.c so we can get the same hash when we're generating patch-ids for 'format-patch --base=' types of command invocations.

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.
