The following INFORMATION_SCHEMA views were unnecessarily retrieving the data from the SYS_TABLESPACES table instead of directly fetching it from the fil_system cache: information_schema.innodb_tablespaces_encryption information_schema.innodb_tablespaces_scrubbing InnoDB always loads all tablespace metadata into memory at startup and never evicts it while the tablespace exists. With this fix, accessing these views will be much faster and use less memory, and include data about all tablespaces, including undo tablespaces. The view information_schema.innodb_sys_tablespaces will still reflect the contents of the SYS_TABLESPACES table.

The test will still time out. That should be addressed in MDEV-8139.

fil_iterate(), fil_tablespace_iterate(): Replace os_file_read() with os_file_read_no_error_handling(). os_file_read_func(), os_file_read_no_error_handling_func(): Do not retry partial reads. There used to be an infinite amount of retries. Because InnoDB extends both data and log files upfront, partial reads should be impossible during normal operation.

Initialize block.page.zip only once. PageConverter::update(): Initialize m_page_zip_ptr as late as possible. (We should really remove it at some point.) PageConverter::operator(): Refer to block->page.zip instead of m_page_zip_ptr. AbstractCallback::get_frame(): Define static. Refer to block->page.zip.data directly. fil_iterate(): Refer to block->page.zip.data directly. fil_tablespace_iterate(): Initialize block.page.zip.data as soon as possible.

assert on UTF-8 columns Problem: ======= (1) Multi-byte character cases are not considered during prefix index cluster optimization check. It leads to fetch of improper results during read operation. (2) Strict assert in row_sel_field_store_in_mysql_format_func and it asserts for prefix index record to mysql conversion. Solution: ======== (1) Consider the case of multi-byte character during prefix index cluster optimization check. (2) Relax the assert in row_sel_field_store_in_mysql_format_func to allow prefix index record to mysql format conversion. The patch is taken from https://github.com/laurynas-biveinis/percona-server/commit/1eee538087ffcf121c37f844b447ba5480faf081

Refs: MW-245 - changed logic so that in non primary node it is possible to do SET + SHOW + SELECT from information and pfs schema, when dirty reads are not enabled - however, non table selects are not allowed (e.g. SELECT 1)

Refs MW-245 - logic was wrong in detecting if queries are allowed in non primary node. it allowed select with no table list to execute even if dirty reads was not specified

MDEV-10991: Server crashes in spider_udf_direct_sql_create_conn - tests in spider/oracle* suites crash the server The crash occurs due to code that is #ifdef'd out with HAVE_ORACLE_OCI that pertains to the use of Spider with an Oracle data tier. Enabling this code eliminates the crash. The reason that MariaDB needs to support Oracle storage at the data tier is to help customers migrate from Oracle. It is necessary to build Spider with the additional build flag -DHAVE_ORACLE_OCI, and install and start Oracle before running the Oracle test suite or any tests within it. Nevertheless, if Spider is built normally and Oracle has not been started, these tests should not cause the MariaDB server to crash. The bug fix replaces the crash with the following error: ERROR 12501 (HY000) at line 4: The connect info 'ORACLE' is invalid Author: Jacob Mathew. Reviewer: Kentoku Shiba.

Learn both valgrind and asan to catch this bug: mem_heap_t* heap = mem_heap_create(1024); byte* p = reinterpret_cast<byte*>(heap) + sizeof(mem_heap_t); *p = 123; Overflows of the last allocation in a block will be catched too. mem_heap_create_block(): poison newly allocated memory

cmp_item_sort_string::store_value() did not cache the string returned from item->val_str(), whose result can point to various private members such as Item_char_typecast::tmp_value. - cmp_item_sort_string::store_value() remembered the pointer returned from item->val_str() poiting to tmp_value into cmp_item_string::value_res. - Later, cmp_item_real::store_value() was called, which called Item_str_func::val_real(), which called Item_char_typecast::val_str(&tmp) using a local stack variable "String tmp". Item_char_typecast::tmp_value was overwritten and become a link to "tmp": tmp_value.Ptr freed its own buffer and set to point to the buffer owned by "tmp". - On return from Item_str_func::val_real(), "String tmp" was destructed, but "tmp_value" still pointed to the buffer owned by "tmp", So tmp_value.Ptr became invalid. - Then cmp_item_sort_string() passed cmp_item_string::value_res to sortcmp(). At this point, value_res still pointed to an invalid value of Item_char_typecast::tmp_value. Fix: changing cmp_item_sort_string::store_value() to force copying to cmp_item_string::value if item->val_str(&value) returned a different pointer (instead of &value).
