In all InnoDB row formats, the pointers or lengths stored in the record
header can be at most 14 bits, that is, count up to 16383.
In ROW_FORMAT=REDUNDANT, this limits the maximum possible record length
to 16383 bytes. In other ROW_FORMAT, it could merely limit the maximum
length of variable-length fields.
When MySQL 5.7 introduced innodb_page_size=32k and 64k, the maximum
record length was limited to 16383 bytes (I hope 16383, not 16384,
to be able to distinguish from a record whose length is 0 bytes).
This change is present in MariaDB Server 10.2.
btr_cur_optimistic_update(): Restrict maximum record size to 16K-1
for REDUNDANT and 64K page size.
dict_index_too_big_for_tree(): The maximum allowed record size
is half a B-tree page or 16K(-1 for REDUNDANT) for 64K page size.
convert_error_code_to_mysql(): Fix error message to print
correct limits.
my_error_innodb(): Fix error message to print correct limits.
page_zip_rec_needs_ext() : record size was already restricted to 16K.
Restrict REDUNDANT to 16K-1.
rem0rec.h: Introduce REDUNDANT_REC_MAX_DATA_SIZE (16K-1)
and COMPRESSED_REC_MAX_DATA_SIZE (16K).
support ha_innodb.so as a dynamic plugin.
* remove obsolete *,innodb_plugin.rdiff files
* s/--plugin-load=/--plugin-load-add=/
* MYSQL_PLUGIN_IMPORT glob_hostname[]
* use my_error instead of push_warning_printf(ER_DEFAULT)
* don't use tdc_size and tc_size in a module
update test cases (XtraDB is 5.6.14, InnoDB is 5.6.10)
* copy new tests over
* disable some tests for (old) InnoDB
* delete XtraDB tests that no longer apply
small compatibility changes:
* s/HTON_EXTENDED_KEYS/HTON_SUPPORTS_EXTENDED_KEYS/
* revert unnecessary InnoDB changes to make it a bit closer to the upstream
fix XtraDB to compile on Windows (both as a static and a dynamic plugin)
disable XtraDB on Windows (deadlocks) and where no atomic ops are available (e.g. CentOS 5)
storage/innobase/handler/ha_innodb.cc:
revert few unnecessary changes to make it a bit closer to the original InnoDB
storage/innobase/include/univ.i:
correct the version to match what it was merged from
