[PATCH v2 00/19] hashmap bug/safety/ease-of-use fixes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Patches 1-11 are largely unchanged from the original series with the
exception of 2, which is new and posted at:

	https://public-inbox.org/git/20190908074953.kux7zz4y7iolqko4@whir/

12-17 take further steps to get us away from hashmap_entry being
the first element, but they're also a bit ugly because __typeof__
isn't portable

18-19 finally brings me to the APIs I want to expose without
relying on __typeof :)

Apologies for the delays, been busy with other stuff...

      diff: use hashmap_entry_init on moved_entry.ent
      coccicheck: detect hashmap_entry.hash assignment
      packfile: use hashmap_entry in delta_base_cache_entry
      hashmap_entry_init takes "struct hashmap_entry *"

      hashmap_get takes "const struct hashmap_entry *"
      hashmap_remove takes "const struct hashmap_entry *"
      hashmap_put takes "struct hashmap_entry *"
      introduce container_of macro
      hashmap_get_next returns "struct hashmap_entry *"
      hashmap: use *_entry APIs to wrap container_of
      hashmap_get{,_from_hash} return "struct hashmap_entry *"
      hashmap_cmp_fn takes hashmap_entry params
      hashmap: use *_entry APIs for iteration

      hashmap: introduce hashmap_free_entries
      OFFSETOF_VAR macro to simplify hashmap iterators
