    The config param innodb_thread_concurrency is dynamically set and is

Issue #126: When another thread is buffering an insert for the record
that is being purged, it should invoke buf_pool_watch_notify(), so
that the purge will not be buffered. Otherwise, the purge would be
buffered for the wrong record (one that was inserted after the purge
determined that the record can be removed).

When deletes are not buffered, the latch on the secondary index page
would prevent the insert from occurring.  In delete buffering, the
buf_pool_watch replaces the page latch when the page is not in the
buffer pool.

buf_pool_watch_notify(): Make public.

ibuf_insert(): Invoke buf_pool_watch_notify() when buffering an
insert or a delete-mark operation.

  * Remove a change from win-plugin/win-plugin.diff about time_t because
    MySQL has used VS2005 for building 5.1.30.

  * Adjust the line numbers so the patch applies cleanly without fuzz and
    offset messages.

  branches/zip: Always check for "row too large" when executing SQL to create
  an index or table.  We have to skip this check when loading table definitions
  from the data dictionary, because we could otherwise refuse to load old
  tables (even uncompressed ones).  This addresses Issue #119.

  The first "row too large" check was implemented in MySQL 5.0.3
  to address MySQL Bug #5682.  In the InnoDB Plugin 1.0.2, a more
  accurate check was implemented in innodb_strict_mode.  We now
  make the check unconditional.

  trx_is_strict(), thd_is_strict(): Remove.

  branches/zip: implement the delayloading of externals for the plugin
  on Windows, which includes:

   * Load mysqld.map and insert all symbol/address pairs into hash for
     quick access
   * Resolves all external data variables. The delayloading mechanism
     in MSVC does not support automatic imports of data variables.
     A workaround is to explicitly handle the data import using the delay
     loader during the initialization of the plugin.
   * Resolves all external functions during run-time, by implementing
     the delayed loading helper function delayLoadHelper2, which is
     called by run-time as well as HrLoadAllImportsForDll. 

  The delay loader reuses the hash implementation in InnoDB. The normal
  hash_create (in hash0hash.c) creates hash tables in buffer pool. But
  the delay loader is invoked before the engine is initialized, and 
  buffer pools are not ready yet. Instead, the delay loader has its own
  implementation of hash_create() and hash_table_free(), called
  wdl_hash_create() and wdl_hash_table_free().

  This patch should be used with other two patches in order to build
  a dynamically linked plugin on Windows:
   * patch for tmpfile functions (r2886)
   * patch for "build" files (to be committed)

  The list of file changed:

  handler/handler0vars.h: new file, defines a list of external data
  variables (no external functions).

  handler/win_delay_loader.cc: new file, the implementation of the delay
  loader for Windows plugin.

    When MySQL Bug #20877 was fixed in r834, this function was
    accidentally modified to return 0 or 1. Apparently, the only impact of
    this bug is that fixed-length columns cannot be updated in-place from
    or to SQL NULL, even in ROW_FORMAT=REDUNDANT.  After this fix,
    fixed-length columns in ROW_FORMAT=REDUNDANT will have a constant
    storage size as they should, no matter if NULL or non-NULL.  The bug
    caused fixed-length NULL columns to occupy 1 byte.

  uncompressed page size by redefining UNIV_PAGE_SIZE_SHIFT in univ.i.
  Currently, the allowed values are 12, 13, or 14 (4k, 8k, 16k).

  Make the default compressed page size half the uncompressed page size.
  The previous default was 8 kilobytes, which is the same when compiling
  with the default 16k uncompressed page size.

delete-mark operation, do not count the buffered records.  The count
is only relevant for buffering IBUF_OP_DELETE operations.

ibuf_get_volume_buffered(): Do not count the records if n_recs is NULL.
Do not zero out *n_recs, but let the caller do that.

ibuf_get_volume_buffered_count(): Do nothing if n_recs == NULL.

reintroduced in r2970.

ibuf_get_volume_buffered_hash(): Add the parameters "types" and "data".
The bug was that "types" lacked the offset IBUF_REC_INFO_SIZE, and the
type information would be read from the wrong place.

that were accidentally committed in r2971:

univ.i, ha_innobase::create(): Reduce the uncompressed page size from
16 to 4 kilobytes.

btr_cur_search_to_nth_level(): Print a diagnostic message when the
leaf page of a secondary index is being requested from the disk.

buf_read_ahead_random(), buf_read_ahead_linear(): Disable.

Invoke ibuf_get_volume_buffered_count() as many times as
ibuf_rec_get_volume(rec), so that *n_recs will be updated as appropriate.
This fixes Issue #82: some deletes will be buffered in purge.

delete buffering is not fundamentally flawed.  It merely failed because
of other bugs.

was incorrectly returned.

This is because ibuf_rec_get_volume() only returns nonzero for inserts.

insert buffer bitmap when buffering deletes or delete-marks.

TODO: ibuf_get_volume_buffered() should return only the volume of

(r2962, r2865, r2864) and do not refuse to buffer deletes.  The
problem with refusing to buffer deletes was that no deletes were
buffered.

Instead, when merging delete requests, disregard a delete request
if it would make the page empty.  InnoDB tolerates redundant secondary
index records, but not empty pages.

ibuf_delete(): When merging a delete request, print and ignore the record
if the page would become empty.

records on a page, count each unique buffered record at most once.

ibuf_get_volume_buffered_hash(): New function, for inserting a hashed record
into a bit array.

ibuf_get_volume_buffered_count(): New function, refactored from
ibuf_get_volume_buffered(), for counting the unique records buffered for
the page.

ibuf_get_volume_buffered(): Define hash_bitmap, a bit array for identifying
duplicate records.  Hash collisions do not hurt correctness, only performance.
If the number of records on the page is estimated as 0, deletes will not be
buffered.

This patch is just for the record, as is rb://44.  In the tests run so far,
the function ibuf_get_volume_buffered() always seems to estimate the number
of records as 0, disabling all buffered deletes.

ibuf_get_volume_buffered(): Correct the grammar of the function comment.
