D.4.54. Alterações na distribuição 3.23.7 (10 Dec 1999)

  • Fixed workaround under Linux to avoid problems with pthread_mutex_timedwait, which is used with INSERT DELAYED. See Secção 2.6.2, “Notas Linux (Todas as versões)”.

  • Fixed that one will get a 'disk full' error message if one gets disk full when doing sorting (instead of waiting until we got more disk space).

  • Fixed a bug in MyISAM with keys > 250 characters.

  • In MyISAM one can now do an INSERT at the same time as other threads are reading from the table.

  • Added max_write_lock_count variable to mysqld to force a READ lock after a certain number of WRITE locks.

  • Inverted flag delay_key_write on show variables.

  • Renamed concurrency variable to thread_concurrency.

  • The following functions are now multi-byte-safe: LOCATE(substr,str), POSITION(substr IN str), LOCATE(substr,str,pos), INSTR(str,substr), LEFT(str,len), RIGHT(str,len), SUBSTRING(str,pos,len), SUBSTRING(str FROM pos FOR len), MID(str,pos,len), SUBSTRING(str,pos), SUBSTRING(str FROM pos), SUBSTRING_INDEX(str,delim,count), RTRIM(str), TRIM([[BOTH | TRAILING] [remstr] FROM] str), REPLACE(str,from_str,to_str), REVERSE(str), INSERT(str,pos,len,newstr), LCASE(str), LOWER(str), UCASE(str) and UPPER(str); patch by Wei He.

  • Fix core dump when releasing a lock from a non-existent table.

  • Remove locks on tables before starting to remove duplicates.

  • Added option FULL to SHOW PROCESSLIST.

  • Added option --verbose to mysqladmin.

  • Fixed problem when automatically converting HEAP to MyISAM.

  • Fixed bug in HEAP tables when doing insert + delete + insert + scan the table.

  • Fixed bugs on Alpha with REPLACE() and LOAD DATA INFILE.

  • Added interactive_timeout variable to mysqld.

  • Changed the argument to mysql_data_seek() from ulong to ulonglong.
