branches/zip: Remove update-in-place-in-select from the internal SQL
interpreter. It was only used for updating the InnoDB internal data
dictionary when renaming or dropping tables. It could have caused
deadlocks after acquiring latches on insert buffer bitmap pages.
This and r3544 should fix Issue #135.
Furthermore, the update-in-place-in-select does not account for
compression failure. That was not a problem yet, since the InnoDB SQL
interpreter has so far assumed ROW_FORMAT=REDUNDANT.

then in BTR_DELETE mode), let BTR_DELETE take care of checking that
the record can be purged, and either buffering or performing the

row_purge_poss_sec(): New function, to check if it is possible to
purge a secondary index record. Refactored from
row_purge_remove_sec_if_poss_low().
row_purge_remove_sec_if_poss_nonbuffered(): Rename to
row_purge_remove_sec_if_poss_tree(). Remove the parameter mode

btr_cur_search_to_nth_level(): Remove BTR_WATCH_LEAF. As a side

BTR_DELETE cannot be buffered, attempt btr_cur_optimistic_delete().
Either way, check row_purge_poss_sec(). Move the code to set

watch. This should fix the race condition that seems to have caused
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.

message:
A fix for Bug#22891 "session level max_allowed_packet can be
set but is ignored".
This patch makes @@session.max_allowed_packed and
@@session.net_buffer_length read-only as suggested in the bug
report. The user will have to use SET GLOBAL (and reconnect)
to alter the session values of these variables.
The error string ER_VARIABLE_IS_READONLY is introduced.
Tests are modified accordingly.

This is to fix issues introduced by recovery enhancements committed

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).

loader for Windows plugin.

branches/5.1: dtype_get_sql_null_size(): return the correct storage
size of a SQL NULL column. (Bug #40369)
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.

Fix "Bug#40360 Binlog related errors with binlog off" in InnoDB code in order

In case MySQL does develop another solution to this via Bug#40360 then we can

mysql_bin_log_is_engaged() inside mysql_addons.cc instead of in mysql's log.cc
and use a different name for it so there is no collision when MySQL adds this
function in log.cc.
[note from the future: the windows part of this patch went into r2947]

available.
External variable builtin_innobase_plugin is not available when mysqld
does not have a builtin InnoDB. The init of the Windows plugin should
not fail in this case.

branches/zip: windows plugin - fix references to array variables.
This problem surfaced when running new test innodb_bug40360.test. Both
tx_isolation_names and binlog_format_names are name arrays, and
should be defined as wdl_tx_isolation_names and wdl_binlog_format_names,
not *wdl_tx_isolation_names and *wdl_binlog_format_names.
Another array variable is all_charsets, which is already correctly
defined.

branches/zip: ha_innobase::create(): Remove the dependences on
DICT_TF_ZSSIZE_MAX, so that the code can be compiled with a different
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

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

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.

TODO: ibuf_get_volume_buffered() should return only the volume of
the buffered inserts, not deletes or delete-marks.
(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.
