Thanks to references from Brad Smith, BSDs use getmntinfo as a system call for mounted filesystems. Most BSDs return statfs structures, (and we use OSX's statfs64), but NetBSD uses a statvfs structure. Simplify Linux getmntent_r to just use getmntent. AIX uses getmntent. An attempt at writing Solaris compatibility with a small bit of HPUX compatibility was made based on man page entries only. Fixes welcome. statvfs structures now use f_bsize for consistency with statfs Test case adjusted as PATH_MAX is OS defined (e.g. 1023 on AIX) Fixes: 0ee5cf83 also fixes: MDEV-27818: Disk plugin does not show zpool mounted devices This is because zpool mounted point don't begin with /. Due to the proliferation of multiple filesystem types since this was written, we restrict the entries listed in the disks plugin to excude: * read only mount points (no point monitoring, and includes squash, snaps, sysfs, procfs, cgroups...) * mount points that aren't directories (excludes /etc/hostname and similar mounts in containers). (getmntent (Linux/AIX) only) * exclude systems where there is no capacity listed (excludes various virtual filesystem types). Reviewer: Sergei Golubchik

Add ORDER BY to make the test deterministic. Add FLUSH TABLES to avoid crash recovery warnings about the table mysql.plugin. This tends to occur on Valgrind, where the server shutdown could presumably time out, resulting in a forced kill.

dict_table_rename_in_cache(), dict_table_get_highest_foreign_id(): Reserve sufficient space for the fkid[] buffer, and ensure that the fkid[] will be NUL-terminated. The fkid[] must accommodate both the database name (which is already encoded in my_charset_filename) and the constraint name (which must be converted to my_charset_filename) so that we can check if it is in the format databasename/tablename_ibfk_1 (all encoded in my_charset_filename).

trx_undo_page_report_rename(): Use the correct maximum length of a table name. Both the database name and the table name can be up to NAME_CHAR_LEN (64 characters) times 5 bytes per character in the my_charset_filename encoding. They are not encoded in UTF-8! fil_op_write_log(): Reserve the correct amount of log buffer for a rename operation. The file name will be appended by mlog_catenate_string(). rename_file_ext(): Reserve a large enough buffer for the file names.

MDEV-18873 Server crashes in Compare_identifiers::operator or in my_strcasecmp_utf8 upon ADD PERIOD IF NOT EXISTS with empty name empty identifier specified as `` ends up with a NULL LEX_CSTRING::str in lexer. This is not considered correct in upper layers, for example in Compare_identifiers::operator(). Empty column name is usually avoided by a check_column_name() call while parsing, and period name matches the column name completely. Hence, this fix uses the mentioned call for verification, too.

This bug affected some queries with an IN/ALL/ANY predicand or an EXISTS predicate whose subquery contained a GROUP BY clause that could be eliminated. If this clause used a IN/ALL/ANY predicand whose left operand was a single-value subquery then execution of the query caused a crash of the server after invokation of remove_redundant_subquery_clauses(). The crash was caused by an attempt to exclude the unit for the single-value subquery from the query tree for the second time by the function Item_subselect::eliminate_subselect_processor(). This bug had been masked by the bug MDEV-28617 until a fix for the latter that properly excluded units was pushed into 10.3. Approved by Oleksandr Byelkin <sanja@mariadb.com>

buf_defer_drop_ahi(): Remove. Ever since commit c7f8cfc9 (MDEV-27700) it is safe to invoke btr_search_drop_page_hash_index(block, true) to remove an orphan adaptive hash index. Any attempt to upgrade page latches is prone to deadlocks. Recently, we observed a few hangs that involved nothing more than a small table consisting of one clustered index page, one secondary index page and some undo pages.

- InnoDB fts table initially added to LRU table cache while creating the table. Later, table was marked as non-evicted when we add the table to fts optimizer list. Before marking the table as non-evicted, master thread can try to evict the fts table.

MDEV-29319 Assertion failure size_in_header >= space.free_limit in fsp_get_available_space_in_free_extents() - Race condition between fsp_get_available_space_in_free_extents() and fsp_try_extend_data_file() while accessing space.free_limit. Before calling fsp_get_available_space_in_free_extents(), take shared lock on space->latch.

Problem: ======== When replicating SET DEFAULT ROLE, the pre-update check (i.e. that in set_var_default_role::check()) tries to validate the existence of the given rules/user even when the targeted tables are ignored. When previously issued CREATE USER/ROLE commands are ignored by the replica because of the replication filtering rules, this results in an error because the targeted data does not exist. Solution: ======== Before checking that the given roles/user exist of a SET DEFAULT ROLE command, first ensure that the mysql.user and mysql.roles_mapping tables are not excluded by replication filters.

Reason: ======= Race condition between btr_search_drop_hash_index() and btr_search_lazy_free(). One thread does resizing of buffer pool and clears the ahi on all pages in the buffer pool, frees the index and table while removing the last reference. At the same time, other thread access index->heap in btr_search_drop_hash_index(). Solution: ========= Acquire the respective ahi latch before checking index->freed() btr_search_drop_page_hash_index(): Added new parameter to indicate that drop ahi entries only if the index is marked as freed btr_search_check_marked_free_index(): Acquire all ahi latches and return true if the index was freed

Even though commit b817afaa passed the test mariabackup.compress_qpress, that test turned out to be too small to reveal one more problem that had previously been prevented by the existence of ctrl_mutex. I did not realize that there can be multiple concurrent callers to compress_write(). One of them is the log copying thread; further callers are data file copying threads (default: --parallel=1). By default, there is only one compression worker thread (--compress-threads=1). compress_write(): Fix a race condition between threads that would use the same worker thread object. Make thd->data_avail contain the thread identifier of the submitter, and add thd->avail_cond to notify other compress_write() threads that are waiting for a slot.

- While creating a new InnoDB segment, allocates the extent before allocating the inode or page allocation even though the pages are present in fragment segment. This patch does reserve the extent when InnoDB ran out of fragment pages in the tablespace.

ha_spider::field_exchange() returns NULL and that results in a crash or a assertion failure in spider_db_open_item_ident(). In the first place, there seems to be no need to call field_exchange() for printing an identity (column name with alias). Thus, we simply remove the call.

Analysis: JSON_VALUE() returns "null" string instead of NULL pointer. Fix: When the type is JSON_VALUE_NULL (which is also a scalar) set null_value to true and return 0 instead of returning string.
