      dict.c: fix dictGenericDelete() return ASAP condition. · 67058671
      antirez authored
      Recently we moved the "return ASAP" condition for the Delete() function
      from checking .size to checking .used, which is smarter, however while
      testing the first table alone always works to ensure the dict is totally
      emtpy, when we test the .size field, testing .used requires testing both
      T0 and T1, since a rehashing could be in progress.

      dict.c: introduce dictUnlink(). · afcbcc0e
      oranagra authored
      Notes by @antirez:
      
      This patch was picked from a larger commit by Oran and adapted to change
      the API a bit. The basic idea is to avoid double lookups when there is
      to use the value of the deleted entry.
      
      BEFORE:
      
          entry = dictFind( ... ); /* 1st lookup. */
          /* Do somethjing with the entry. */
          dictDelete(...);         /* 2nd lookup. */
      
      AFTER:
      
          entry = dictUnlink( ... ); /* 1st lookup. */
          /* Do somethjing with the entry. */
          dictFreeUnlinkedEntry(entry); /* No lookups!. */

      DEBUG HTSTATS <dbid> added. · 0f64080d
      antirez authored
      The command reports information about the hash table internal state
      representing the specified database ID.
      
      This can be used in order to investigate rehashings, memory usage issues
      and for other debugging purposes.

      Cleanup wording of dictScan() comment · ef5fc599
      Matt Stancliff authored
      Some language in the comment was difficult
      to understand, so this commit: clarifies wording, removes
      unnecessary words, and relocates some dependent clauses
      closer to what they actually describe.
      
      I also tried to break up longer chains of thought
      (if X, then Y, and Q, and also F, so obviously M)
      into more manageable chunks for ease of understanding.

      Added dictGetRandomKeys() to dict.c: mass get random entries. · 5317f5e9
      antirez authored
      This new function is useful to get a number of random entries from an
      hash table when we just need to do some sampling without particularly
      good distribution.
      
      It just jumps at a random place of the hash table and returns the first
      N items encountered by scanning linearly.
      
      The main usefulness of this function is to speedup Redis internal
      sampling of the key space, for example for key eviction or expiry.

      dict.c: added optional callback to dictEmpty(). · 2eb781b3
      antirez authored
      Redis hash table implementation has many non-blocking features like
      incremental rehashing, however while deleting a large hash table there
      was no way to have a callback called to do some incremental work.
      
      This commit adds this support, as an optiona callback argument to
      dictEmpty() that is currently called at a fixed interval (one time every
      65k deletions).
