in when using vio->read_timeout (and write_timeout) to set
timeouts of a new vio, as in:
vio_timeout(vio, 0, old_vio.read_timeout)
vio_timeout(vio, 0, old_vio.write_timeout)
remember that timeouts are stored in ms, but vio_timeout()'s
argument is in seconds.
On EOF vio_read returns 0, it's not an error so the errno
is not reset. If the previous error was EINTR the client
will loop forever. See also man recv.
* adjust viossl.c to take account the new code
(SSL_get_error is used now, cannot simply remap it)
* remove unnecessary version check
* update the test to 10.0
followup:
* explicitly disable SSLv2 and SSLv3, keep other protocols enabled
* fix a compiler warning
* rename the test and combinations to avoid confusion
vio/viossl.c:
fix a compiler warning
change SSL methods to be SSLv23 (according to openssl manpage:
"A TLS/SSL connection established with these methods may understand
the SSLv2, SSLv3, TLSv1, TLSv1.1 and TLSv1.2 protocols") from
TLSv1 methods, that go back to the initial SSL implementation
in MySQL in 2001.
OpenSSL default ciphers are different if TLSv1.2 is enabled,
so tests need to take this into account.

Bug#18187290 ISSUE WITH BUILDING MYSQL USING CMAKE 2.8.12
We want to upgrade to VS2013 on Windows.
In order to do this, we need to upgrade to cmake 2.8.12
This has introduced some incompatibilities for .pdb files,
and "make install" no longer works.
To reproduce:
cmake --build . --target package --config debug
The fix:
Rather than installing .pdb files for static libraries, we use the /Z7 flag
to store symbolic debugging information in the .obj files.

Rename test() macro to MY_TEST() to avoid conflict with libc++.
ERROR HANDLING CODE
BACKGROUND:
There can be a potential crash due to buffer overrun in
SSL error handling code due to missing comma in
ssl_error_string[] array in viosslfactories.c.
ANALYSIS:
Found by code Inspection.
FIX:
Added the missing comma in SSL error handling code
in ssl_error_string[] array in viosslfactories.c.

This bug only happens with long sleep()s ( > 5 sec), and in debug version.
Analysis:
The assertion is caused by nested thd_wait_begin() calls, which is not an expected condition.
- "outer" thd_wait_begin()) , in Item_func_sleep::val_int()
- "inner" thd_wait_begin() in Interruptible_wait::wait(). This function periodically checks whether connection is still valid, via THD::is_connection(), which ends up calling vio_io_wait() with timeout parameter set to 0.
Fix is not to call thd wait callback in vio_io_wait(), if timeout parameter is 0. There is no "waiting" in this case.
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
