Using --ssl-verify-server-cert and --ssl[-*] implies that
the ssl connection is required. The mysql client will now print an error if ssl
is required, but the server can not handle a ssl connection.
Don't use a fixed buffer for X509_NAME_oneline() in the client.
Do as the server does - allocate it dynamically.
For a test - regenerate certificates to have the server cert with
a long subject.
COMMUNICATION PACKETS; FEDERATED TABLE
Description:- Execution of FLUSH TABLES on a federated
table which has been idle for wait_timeout (on the remote
server) + tcp_keepalive_time, fails with an error,
"ERROR 1160 (08S01): Got an error writing communication
packets."
Analysis:- During FLUSH TABLE execution the federated
table is closed which will inturn close the federated
connection. While closing the connection, federated server
tries to communincate with the remote server. Since the
connection was idle for wait_timeout(on the remote server)+
tcp_keepalive_time, the socket gets closed. So this
communication fails because of broken pipe and the error is
thrown. But federated connections are expected to reconnect
silently. And also it cannot reconnect because the
"auto_reconnect" variable is set to 0 in "mysql_close()".
Fix:- Before closing the federated connection, in
"ha_federated_close()", a check is added which will verify
wheather the connection is alive or not. If the connection
is not alive, then "mysql->net.error" is set to 2 which
will indicate that the connetion is broken. Also the
setting of "auto_reconnect" variable to 0 is delayed and is
done after "COM_QUIT" command.
NOTE:- For reproducing this issue, "tcp_keepalive_time" has
to be set to a smaller value. This value is set in the
"/proc/sys/net/ipv4/tcp_keepalive_time" file in Unix
systems. So we need root permission for changing it, which
can't be done through mtr test. So submitting the patch
without mtr test.
The bug was that my_real_read() called net_before_header_psi() multiple times for long packets.
Fixed by adding a flag when we are reading a header.
Did also some cleanups to interface of my_net_read() to avoid unnecessary calls if performance schema is not used.
- Added my_net_read_packet() as a replacement for my_net_read(). my_net_read() is still in the client library for old clients.
- Removed THD->m_server_idle (not needed anymore as this is now given as argument to my_net_read_packet()
- Added my_net_read_packet(), which is a new version of my_net_read() with a new parameter if we are doing a read for a new command from the server.
- Added tests for compressed protocol and big packets

Bug#17647863: MYSQL DOES NOT COMPILE ON OSX 10.9 GM
Rename test() macro to MY_TEST() to avoid conflict with libc++.
Memory Leak in mysql_options() was caused by missing call
to my_free() in MYSQL_SET_CLIENT_IP branch. Fixed by adding
my_free() to cleanup mysql->options.client_ip value before
assigning new value.
Memory Leak in mysql_options() was caused by missing call
to my_free() in MYSQL_SET_CLIENT_IP branch. Fixed by adding
my_free() to cleanup mysql->options.client_ip value before
assigning new value.
includes:
* remove some remnants of "Bug#14521864: MYSQL 5.1 TO 5.5 BUGS PARTITIONING"
* introduce LOCK_share, now LOCK_ha_data is strictly for engines
* rea_create_table() always creates .par file (even in "frm-only" mode)
* fix a 5.6 bug, temp file leak on dummy ALTER TABLE
Fixed some cases that didn't work with > 4G buffers.
Fixed compiler warnings
include/mysql_com.h:
Avoid compiler warning with strncmp()
sql-common/client.c:
Fixed long comment; Added ()
sql/filesort.cc:
Fix code to get filesort to work with big buffers
sql/sys_vars.cc:
Fixed some cache variables that could be set to higher value than the size_t
Limit query cache to ULONG_MAX as the query cache buffer variables are ulong
storage/federatedx/ha_federatedx.cc:
Remove not used variable
storage/maria/ha_maria.cc:
Fix that bulk_insert() works with big buffers
storage/maria/ma_write.c:
Fix that bulk_insert() works with big buffers
storage/myisam/ha_myisam.cc:
Fix that bulk_insert() works with big buffers
storage/myisam/mi_write.c:
Fix that bulk_insert() works with big buffers
storage/sphinx/snippets_udf.cc:
Fixed compiler warnings
Solaris fixes:
- Fixed that wait_timeout_func and wait_timeout tests works on solaris
- We have to compile without NO_ALARM on Solaris as Solaris doesn't support timeouts on sockets with setsockopt(.. SO_RCVTIMEO).
- Fixed that compile-solaris-amd64-debug works (before that we got a wrong ELF class: ELFCLASS64 on linkage)
- Added missing sync_with_master
Other bug fixes:
- Free memory for rpl_global_gtid_binlog_state before exit() to avoid 'accessing uninitalized mutex' error.
BUILD/FINISH.sh:
Fixed issues on Solaris with ksh
BUILD/compile-solaris-amd64-debug:
Added missing -m64 flag
configure.cmake:
We have to compile without NO_ALARM on Solaris as Solaris doesn't support timeouts on sockets with setsockopt(.. SO_RCVTIMEO)
mysql-test/suite/rpl/t/rpl_gtid_mdev4473.test:
- Added missing sync_with_master (fix by knielsen)
sql-common/client.c:
Added () to get rid of compiler warning
sql/item_strfunc.cc:
Fixed compiler warning
sql/log.cc:
Free memory for static variable rpl_global_gtid_binlog_state before exit()
- If we are compiling with safemalloc, we would try to call sf_free() for some members after sf_terminate() was called, which would result of trying to access the uninitalized mutex 'sf_mutex'
sql/multi_range_read.cc:
Fixed compiler warnings of converting double to ulong.
sql/opt_range.cc:
Fixed compiler warnings of converting double to ulong or uint
- Better to have all variables that can be number of rows as 'ha_rows'
sql/rpl_gtid.cc:
Added rpl_binlog_state::free() to be able to free memory for static objects before exit()
sql/rpl_gtid.h:
Added rpl_binlog_state::free() to be able to free memory for static objects before exit()
sql/set_var.cc:
Fixed compiler warning
sql/sql_join_cache.cc:
Fixed compiler warnings of converting double to uint
sql/sql_show.cc:
Added cast to get rid of compiler warning
sql/sql_statistics.cc:
Remove code that didn't do anything.
(store_record() with record[0] is a no-op)
storage/xtradb/os/os0file.c:
Added __attribute__ ((unused))
support-files/compiler_warnings.supp:
Ignore warnings from atomic_add_64_nv
(was not able to fix this with a cast as the macro is a bit different between systems)
vio/viosocket.c:
Added more DBUG_PRINT
MYSQL_READ_DEFAULT_FILE
Parsing of the plugin-dir config file option was not working due to a typo.
Fixed the typo. No test case can be added due to lack of support for
defaults-exitra-file testing in mysql-test-run.pl.
Thanks to Sinisa for contributing the fix.

update 5.1 to replicate from 10.0 and
to show the server version (as of 10.0) correctly
sql-common/client.c:
mdev:4088
sql/slave.cc:
use the version number, not just the first character of the version string
(we want 10 > 4 not "10" < "4").
