- 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.
DESCRIPTION
===========
PVS-Studio static code analyzer found several suspicious
fragments of code across various files.
i) sizeof() is using the pointer
ii) memcpy() doesn't copy the whole string.
iii) enumeration constant 'wkb_multilinestring' is used as
a variable of a Boolean-type.
iv) 'throw' keyword is missing from std::runtime_error()
FIX
===
i) Use sizeof({actual object/data type})
ii) Use strncpy() and set last char as '\0'
iii) N/A (Issue has already been fixed)
iv) Add 'throw' before the exception.

* fix incorrect parentheses
* if there was no password on the command line or in .cnf file,
pkt will be "", and we need to request the user to enter the password
* wait() for the child process to die, let it rest in peace
* fix incorrect parentheses
* if there was no password on the command line or in .cnf file,
pkt will be "", and we need to request the user to enter the password
* make sure that auth->salt is always allocated on a permanent memroot.
when called from set_user_salt_if_needed(), user_copy and its auth_str
are on the thd memroot, but auth_copy->salt is then copied to auth->salt
* adjust service files so that systemd wouldn't interfere with our
setuid executables
also
* print the pam error message in debug mode
this matches the common behavior with pam_unix and helps to
catch password related errors
also, use abort() instead of sigsegv to avoid polluting
/var/log/messages with intentional crashes
Plugin fixed to not lock the LOCK_operations when not active.
Server fixed to lock the LOCK_plugin less - do it once per
thread and then only if a plugin was installed/uninstalled.
innodb_locks_unsafe_for_binlog variabe removed from wsrep_info test configuration and
recommendation to use this variable in README-wsrep was removed as well
