"git blame" learned to "ignore" commits in the history, whose effects (as well as their presence) get ignored. * br/blame-ignore: t8014: remove unnecessary braces blame: drop some unused function parameters blame: add a test to cover blame_coalesce() blame: use the fingerprint heuristic to match ignored lines blame: add a fingerprint heuristic to match ignored lines blame: optionally track line fingerprints during fill_blame_origin() blame: add config options for the output of ignored or unblamable lines blame: add the ability to ignore commits and their changes blame: use a helper function in blame_chunk() Move oidset_parse_file() to oidset.c fsck: rename and touch up init_skiplist()

/**

* This API is similar to sha1-array, in that it maintains a set of object ids
|
|
* in a memory-efficient way. The major differences are:
|
|
*
|
|
* 1. It uses a hash, so we can do online duplicate removal, rather than
|
|
* sort-and-uniq at the end. This can reduce memory footprint if you have
|
|
* a large list of oids with many duplicates.
|
|
*
|
|
* 2. The per-unique-oid memory footprint is slightly higher due to hash
|
|
* table overhead.
