Monty	c9c689e1a3	Updated prototype of ha_s3::write_row() to get s3 to compile	6 years ago
Monty	fa490e8022	Don't copy uninitialized bytes when copying varstrings When using field_conv(), which is called in case of field1=field2 copy in fill_records(), full varstring's was copied, including unitialized bytes. This caused valgrind to compilain about usage of unitialized bytes when using Aria static length records. Fixed by not using memcpy when copying varstrings but instead just copy the real bytes.	6 years ago
Alexander Barkov	afe6eb499d	Revert "MDEV-20342 Turn Field::flags from a member to a method" This reverts commit `e86010f909`. Reverting on Monty's request, as this change makes merging things from 10.5 to 10.2 much harder.	6 years ago

Thirunarayanan Balathandayuthapani	7772c7cd94	MDEV-20340 Encrypted temporary tables cannot be read with full_crc32 Problem: ======== Checksum for the encrypted temporary tablespace is not stored in the page for full crc32 format. Solution: ======== Made temporary tablespace in full crc32 format irrespective of encryption parameter. buf_tmp_page_encrypt(), buf_tmp_page_decrypt() - Both follows full_crc32 format.	6 years ago

Monty	c4fd167d5a	Fixed access to unitialized memory when using unique HASH key Fixed the following issues: - Call info with HA_STATUS_CONST to ensure that (key_info->rec_per_key) contains latest data - Don't access rec_per_key if key_info->algorithm == HA_KEY_ALG_LONG_HASH is in this case the rec_per_key points to uninitialized data - Cleaned up code to avoid some extra 'if' and to make things more readable - Updated test cases that used 'old' rec_per_key values	6 years ago

Marko Mäkelä	ae1d17f52d	MDEV-20316 InnoDB writes uninitialised tail of XID buffer Starting with commit `210855ce5d` Valgrind became aware that the unused tail of the buffer that is returned by thd_get_xid() is actually uninitialized. The problem should exist already in MySQL 5.0. I was able to repeat it on MariaDB Server 5.5 with some additional instrumentation. InnoDB is allocating 128+4+4 bytes for the XID and the lengths of its components, even when the XID is shorter than 64+64 bytes. In MariaDB Server 10.3, while running the test main.xa_binlog, in the xid_t::set() that is called by sql_yacc.yy, the 128-byte data buffer was uninitialized according to Valgrind, and only the first bytes were initialized. When the xid_t::data was copied to thd.transaction.xid_state.xid.data, it happened so that the entire target buffer was considered initialized. With MariaDB Server 10.4 since the said commit, Valgrind will correctly be detect the tail of the buffer as uninitialized. The impact of this bug is as follows: (1) InnoDB will write unnecessarily much redo log for XA PREPARE. (2) InnoDB will write garbage bytes to the redo log and undo log pages. (3) The garbage should be 'harmless', because on recovery, only the actual payload of the XID will be used, based on the written length. trx_rseg_write_wsrep_checkpoint(), trx_undo_write_xid(): Write only the actually used length of xid->data to the data page, and zero out the rest of the buffer by mlog_memset().	6 years ago

Monty	05619f6989	Fixes based on warnings from gcc/clang and valgrind - Initialize variables that could be used uninitialized - Added extra end space to DbugStringItemTypeValue to get rid of warnings from c_ptr() - Session_sysvars_tracker::update() accessed unitialized memory if called with NULL value. - get_schema_stat_record() accessed unitialized memory if HA_KEY_LONG_HASH was used - parse_vcol_defs() accessed random memory for tables without keys.	6 years ago
