| * MDEV-16128: Server crash in Item_func::print_op on 2nd execution of PSDmitry Shulga2022-10-171-0/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some queries that involve tables with different but convertible character sets for columns taking part in the query, repeatable execution of such queries in PS mode or as part of a stored routine would result in server abnormal termination. For example, CREATE TABLE t1 (a2 varchar(10)); CREATE TABLE t2 (u1 varchar(10) CHARACTER SET utf8); CREATE TABLE t3 (u2 varchar(10) CHARACTER SET utf8); PREPARE stmt FROM "SELECT t1.* FROM (t1 JOIN t2 ON (t2.u1 = t1.a2)) WHERE (EXISTS (SELECT 1 FROM t3 WHERE t3.u2 = t1.a2))"; EXECUTE stmt; EXECUTE stmt; <== Running this prepared statement the second time results in server crash. The reason of server crash is that an instance of the class Item_func_conv_charset, that created for conversion of a column from one character set to another, is allocated on execution memory root but pointer to this instance is stored in an item placed on prepared statement memory root. Below is calls trace to the place where an instance of the class Item_func_conv_charset is created. setup_conds Item_func::fix_fields Item_bool_rowready_func2::fix_length_and_dec Item_func::setup_args_and_comparator Item_func_or_sum::agg_arg_charsets_for_comparison Item_func_or_sum::agg_arg_charsets Item_func_or_sum::agg_item_set_converter Item::safe_charset_converter And the following trace shows the place where a pointer to the instance of the class Item_func_conv_charset is passed to the class Item_func_eq, that is created on a memory root of the prepared statement. Prepared_statement::execute mysql_execute_command execute_sqlcom_select handle_select mysql_select JOIN::optimize JOIN::optimize_inner convert_join_subqueries_to_semijoins convert_subq_to_sj To fix the issue, switch to the Prepared Statement memory root before calling the method Item_func::setup_args_and_comparator in order to place any created Items on permanent memory root. It may seem that such approach would result in a memory leakage in case the parameter marker '?' is used in the query as in the following example PREPARE stmt FROM "SELECT t1.* FROM (t1 JOIN t2 ON (t2.u1 = t1.a2)) WHERE (EXISTS (SELECT 1 FROM t3 WHERE t3.u2 = ?))"; EXECUTE stmt USING convert('A' using latin1); but it wouldn't since for such case any of the parameter markers is treated as a constant and no subquery to semijoin optimization is performed.

| | | | | | | | | | | | | | | | | | | | | | | | krb5-config (used by FindGSSAPI) returns `-lkrb5 -lk5crypto -lcom_err` but only libkrb5 is actually used by the gssapi plugin. The other two result in unneeded dependencies unless they're tagged optional when linked with --as-needed. Some distributions use --as-needed automatically, which causes our builds to differ from srpm builds, introducing failures in buildbot. Let's always use --as-needed for gssapi plugin

| | | | | | | | | | | | | | | | | | Test fixes: Since fix for CONC-603 (wrong error handling in TLS read/write) in case of a read/write error client doesn't return always error 2013 (server has gone away), so in addition we need to check for error 2026 (TLS/SSL error) and 5014 (write error).
