This patch adds for "--ps-protocol" second execution
of queries "SELECT".
Also in this patch it is added ability to disable/enable
(--disable_ps2_protocol/--enable_ps2_protocol) second
execution for "--ps-prototocol" in testcases.
During the upgrade procedure on Windows mysqld.exe is started with
the named pipe connection protocol. mysqladmin.exe then pings the
server to check if is up and running. Command line looks like:
mysqladmin.exe --protocol=pipe --socket=mysql_upgrade_service_xxx ping
But the "socket" parameter resets the "protocol" which was previously
initialized with the "pipe" value, setting it to "socket".
As a result, connection cannot be established and the upgrade
procedure fails.
"socket" in Windows is used to pass the name of the pipe so resetting
the protocol is not valid in this case.
This commit fixes resetting of the "protocol" parameter with "socket"
parameter in the case when protocol has been previously initialized
to "pipe" value

- Moved view checks after privilege tables are fixed. This is to avoid
warnings about wrongly defined mysql.proc when checking views.
- Don't use stat tables before they have been fixed.
- Don't run mysql_fix_view() if 'FOR MYSQL' is used if the view is
already a MariaDB view.
- Added 'FOR UPGRADE' as an option for 'REPAIR VIEW' to be able to
detect if the REPAIR command comes from mariadb_upgrade. In this
case we get a warning, instead of an error, if a definer of a view
does not exists.
mysqltest should use the same collation_connection in the service
connection (that creates views) as in the main connection
this makes weight_string("aaa") to return the expected value in --view
and fixes main.func_str failure in --view
The old code added to 10.6 was inconsisting in how TCP/IP and
socket connection was chosen. One got also a confusing warning
in some cases.
Examples:
> ../client/mysql --print-defaults
../client/mysql would have been started with the following arguments:
--socket=/tmp/mariadbd.sock --port=3307 --no-auto-rehash
> ../client/mysql
ERROR 2002 (HY000): Can't connect to local server through socket '/tmp/mariadbd.sock' (2)
> ../client/mysql --print-defaults
../client/mysql would have been started with the following arguments:
--socket=/tmp/mariadbd.sock --port=3307 --no-auto-rehash
> ../client/mysql --port=3333
WARNING: Forcing protocol to TCP due to option specification. Please explicitly state intended protocol.
ERROR 2002 (HY000): Can't connect to server on 'localhost' (111)
> ../client/mysql --port=3333 --socket=sss
ERROR 2002 (HY000): Can't connect to local server through socket 'sss' (2)
> ../client/mysql --socket=sss --port=3333
ERROR 2002 (HY000): Can't connect to local server through socket 'sss' (2)
Some notable things:
- One gets a warning if one uses just --port if config file sets socket
- Using port and socket gives no warning
- Using socket and then port still uses socket
This patch changes things the following ways:
If --port= is given on the command line, the the protocol is automatically
changed to "TCP/IP".
- If --socket= is given on the command line, the protocol is automatically
changed to "socket".
- The last option wins
- No warning is given if protocol changes automatically.
do_shutdown_server(): After sending SIGKILL, invoke wait_until_dead().
Thanks to Sergei Golubchik for pointing out that the previous fix
does not actually work.
do_shutdown_server(): Call wait_until_dead() also when we are forcibly
killing the process (timeout=0). We have evidence that killing
the process may take some time and cause mystery failures in
crash recovery tests. For InnoDB, several failures were observed between
commit da094188f6 and
commit 0ee1082bd2
when no advisory file locking was being used by default.
The tests innodb.import_tablespace_race, innodn.restart, and innodb.innodb-wl5522 move
the tablespace file between the data directory and the tmp directory specified by
global environment variables. However this is risky because it's not unusual that the
set tmp directory (often under /tmp) is mounted on another disk partition or device,
and 'move_file' command may fail with "Errcode: 18 'Invalid cross-device link.'"
To stabilize mysqltest in the described scenario, and prevent such
behavior in the future, let make_file() check both from file path and to
file path and make sure they are either both under MYSQLTEST_VARDIR or
MYSQL_TMP_DIR.

While performing SAST scanning using Cppcheck against source code of
commit 81196469, several code vulnerabilities were found.
Fix following issues:
1. Parameters of `snprintf` function are incorrect.
Cppcheck error:
client/mysql_plugin.c:1228: error: snprintf format string requires 6 parameters but only 5 are given.
It is due to commit 630d7229 introduced option `--lc-messages-dir`
in the bootstrap command. However the parameter was not even given
in the `snprintf` after changing the format string.
Fix:
Restructure the code logic and correct the function parameters for
`snprintf`.
2. Null pointer is used in a `snprintf` which could cause a crash.
Cppcheck error:
extra/mariabackup/xbcloud.cc:2534: error: Null pointer dereference
The code intended to print the swift_project name, if the
opt_swift_project_id is NULL but opt_swift_project is not NULL.
However the parameter of `snprintf` was mistakenly using
`opt_swift_project_id`.
Fix:
Change to use the correct string from `opt_swift_project`.
3. Potential double release of a memory
Cppcheck error:
plugin/auth_pam/testing/pam_mariadb_mtr.c:69: error: Memory pointed to by 'resp' is freed twice.
A pointer `resp` is reused and allocated new memory after it has been
freed. However, `resp` was not set to NULL after freed.
Potential double release of the same pointer if the call back
function doesn't allocate new memory for `resp` pointer.
Fix:
Set the `resp` pointer to NULL after the first free() to make sure
the same address is not freed twice.
