open by adding a simple condition that checks whether one of them opens
while the other fails and closing it
and added the extra prentheses for the assignment inside the if statement
for easier debugging and to avoid static analysis flagging it as a wrong
statement inside the if clause
Fixed different behavior of pvio_is_alive (which was first used
with fix of CONC-589). Both for sockets and named pipe the function
now returns true if the connection is alive, otherwise false.
If automatic reconnect is enabled (MYSQL_OPT_RECONNECT) it is
mandatory to check if the connection/socket is still alive before
sending a command to the server (unless the command is COM_QUIT).
- Build server build with latest C/C: Instead of copying the C/C directory
into server, we now fetch the actual commit or PR into server repository
- Fix travis environment variables (Windows)
- Skip character set tests if the server doesn't support charset/collation
- Don't use CREATE OR REPLACE SQL syntax to make MySQL happy
- Disable TLS connection test for MaxScale
- Don't set TEST environment variables if they are empty
- Added TLSv1.3 ciphers to cipher map.
- Fixed retrieval of cipher suite: Since gnutls_cipher_suite_get_name
supports only TLSv1.2 (and lower) cipher suites, we have to call
gnutls_ciphersuite_get() (requires GnuTLS 3.7.4 or newer).
This reverts 395641549ac7..536d9e2b9e5b, in particular:
8dffd56936 MDEV-31857 enable MYSQL_OPT_SSL_VERIFY_SERVER_CERT by default
a99570c118 MDEV-31855 SSL cert validation protocol extension
9aa15e72a7 TLS fingerprint
and related commits
because the default value of every option is 0
(option and option.extension are bzero-ed to reset),
tls_verify_server_cert was renamed to tls_allow_invalid_server_cert
with the default value of 0, "do not allow".
API didn't change, it's still MYSQL_OPT_SSL_VERIFY_SERVER_CERT
Skip character set tests which set character set
during handshake, since MaxScale sends utf8mb4 via
session_track information in handshake OK packet.
(https://jira.mariadb.org/browse/MXS-4898).
When resetting the connection with mysql reset_connection(), the
server_status must be checked and any other resultsets that mayi
exist must be removed.
This feature allows client applications to register a callback function,
which is called as soon as the server status changes or session_track
information was sent by the server.
Registration is handled via mysql_optionsv() API function:
mysql_optionsv(mysql, MARIADB_OPT_STATUS_CALLBACK, function, data)
The callback function must be defined as follws:
void status_callback(void *data, enum enum_mariadb_status_info type, ..)
Parameters:
- data Pointer passed with registration of callback function
(usually a connection handle)
- type Information type STATUS_TYPE or SESSION_TRACK_TYPE
Variadic Parameters:
if (type == STATUS_TYPE):
- server status (unsigned int)
if (type == SESSION_TRACK_TYPE)
- enum enum_session_state_type track_type - session track type
if (track_type == SESSION_TRACK_SYSTEM_VARIABLES)
- MARIADB_CONST_STRING *key
- MARIADB_CONST_STRING *value
else
- MARIADB_CONST_STRING *value
An example can be found in connection.c (test_status_callback)
Since Connector/C is not able to retrieve
error strings for server error codes, the following
error codes were replaced:
- ER_NET_PACKET_TOO_LARFE by CR_NET_PACKET_TOO_LARGE
- ER_OUT_OF_RESOURCES by CR_OUT_OF_MEMORY
- ER_NET_WRITE_ERROR by CR_ERR_NET_WRITE (new constant)
- ER_NET_UNCOMPRESS_ERROR by CR_ERR_NET_UNCOMPRESS (new constant)
ZSTD compression is now supported for connections
to a MySQL Server 8.0.
Compression algorithms are supported via compression
plugins, which can be found in plugins/compress.
- For reconnection/and multi host tests specify also socket location,
since mtr doesn't use default socket for localhost connections
- parse_connection_string now returns NULL for empty password in
curly braces
