  branches/zip: Enclose some more unused code in #ifdef UNIV_LOG_ARCHIVE.
  This will help trim the dependencies of InnoDB Hot Backup.

  recv_recovery_from_checkpoint_start(): Rename to
  recv_recovery_from_checkpoint_start_func(), and remove the two first
  parameters unless UNIV_LOG_ARCHIVE is defined.  Define and use
  the auxiliary macros TYPE_CHECKPOINT and LIMIT_LSN in the function.

  struct recv_sys_struct: Remove archive_group unless UNIV_LOG_ARCHIVE
  is defined.

  Do not define LOG_ARCHIVE unless UNIV_LOG_ARCHIVE is defined.

    branches/5.1: Merge r4031 from branches/5.0:

    btr_search_drop_page_hash_when_freed(): Check if buf_page_get_gen()
    returns NULL.  The page may have been evicted from the buffer pool
    between buf_page_peek_if_search_hashed() and buf_page_get_gen(),
    because the buffer pool mutex will be released between these two calls.
    (Bug #42279, Issue #160)

  that was introduced in r4030.

  r4036 | marko | 2009-01-26 22:33:20 +0200 (Mon, 26 Jan 2009) | 22 lines

  branches/zip: In r988, the function buf_block_align() was enclosed
  within UNIV_DEBUG. The two remaining callers in non-debug builds,
  btr_search_guess_on_hash() and btr_search_validate(), were rewritten
  to call buf_page_hash_get().

  To implement support for a resizeable buffer pool, the function
  buf_block_align() had been rewritten to perform a page hash lookup in
  the buffer pool. The caller was also made responsible for holding the
  buffer pool mutex.

  Because the page hash lookup is expensive and it has to be done while
  holding the buffer pool mutex, implement buf_block_align() by pointer
  arithmetics again, and make btr_search_guess_on_hash() call it. Note
  that this will have to be adjusted if the interface to the resizeable
  buffer pool is actually implemented.

  rb://83 approved by Heikki Tuuri, to address Issue #161.

  As a deviation from the approved patch, this patch also makes
  btr_search_validate() (invoked by CHECK TABLE) check that
  buf_pool->page_hash is consistent with buf_block_align().

  branches/zip: btr_search_validate(): Fix a bogus UNIV_DEBUG
  assertion failure that was accidentally introduced in r4036.
  Instead of calling buf_block_get_frame(), which asserts that the
  block must be buffer-fixed, access block->frame directly.  That
  is safe, because changes of block->page.state are protected by
  the buffer pool mutex, which we are holding.

  This bug was reported by Michael.

  introduced in r4036.
  Do not call buf_block_get_space(), buf_block_get_page_no()
  unless the block state is BUF_BLOCK_FILE_PAGE.

      message:
        Bug#31177: Server variables can't be set to their current values

        Bounds-checks and blocksize corrections were applied to user-input,
        but constants in the server were trusted implicitly. If these values
        did not actually meet the requirements, the user could not set change
        a variable, then set it back to the (wonky) factory default or maximum
        by explicitly specifying it (SET <var>=<value> vs SET <var>=DEFAULT).

        Now checks also apply to the server's presets. Wonky values and maxima
        get corrected at startup. Consequently all non-offsetted values the user
        sees are valid, and users can set the variable to that exact value if
        they so desire.
