wsrep_append_foreign_key() and wsrep_append_key() used to take a boolean
argument denoting whether the relevant certification key type is shared
(assuming it is exclusive if the argument is false). Change that
argument to the enum wsrep_key_type from wsrep_api.h, so that eventually
other types can also be passed (like WSREP_KEY_SEMI).
This is a non-functional change.
(cherry picked from commit 360bf36dbb9378b36ef57921c725a9505e19e0d9)
ha_innobase::set_partition_owner_stats(): Remove (unused function).
ha_innobase::ha_partition_stats: Remove (the variable is never read).
Remove unused ut_timer functions.
disable online alter add primary key for innodb, if the
table is opened/locked more than once in the current connection
(see assert in ha_innobase::add_index())
This fixes warnings that were emitted when running InnoDB test
suites on a debug server that was compiled with GCC 7.1.0 using
the flags -O3 -fsanitize=undefined.
thd_requested_durability(): XtraDB can call this with trx->mysql_thd=NULL.
Remove the function in InnoDB, because it is not used there.
calc_row_difference(): Do not call memcmp(o_ptr, NULL, 0).
innobase_index_name_is_reserved(): This can be called with
key_info=NULL, num_of_keys=0.
innobase_dropping_foreign(), innobase_check_foreigns_low(),
innobase_check_foreigns(): This can be called with
drop_fk=NULL, n_drop_fk=0.
rec_convert_dtuple_to_rec_comp(): Do not invoke memcpy(end, NULL, 0).
Also, implement MDEV-11027 a little differently from 5.5 and 10.0:
recv_apply_hashed_log_recs(): Change the return type back to void
(DB_SUCCESS was always returned).
Report progress also via systemd using sd_notifyf().
MariaDB Server 10.0.28 and 10.1.19 merged code from Percona XtraDB
that introduced support for compressed columns. Much but not all
of this code was disabled by placing #ifdef HAVE_PERCONA_COMPRESSED_COLUMNS
around it.
Among the unused but not disabled code is code to access
some new system tables related to compressed columns.
The creation of these system tables SYS_ZIP_DICT and SYS_ZIP_DICT_COLS
would cause a crash in --innodb-read-only mode when upgrading
from an earlier version to 10.0.28 or 10.1.19.
Let us remove all the dead code related to compressed columns.
Users who already upgraded to 10.0.28 and 10.1.19 will have the two
above mentioned empty tables in their InnoDB system tablespace.
Subsequent versions of MariaDB Server will completely ignore those tables.
