* MDEV-10138 Support for decimals up to 38 digitsMonty2016-06-224-8/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Decimals with float, double and decimal now works the following way: - DECIMAL_NOT_SPECIFIED is used when declaring DECIMALS without a firm number of decimals. It's only used in asserts and my_decimal_int_part. - FLOATING_POINT_DECIMALS (31) is used to mark that a FLOAT or DOUBLE was defined without decimals. This is regarded as a floating point value. - Max decimals allowed for FLOAT and DOUBLE is FLOATING_POINT_DECIMALS-1 - Clients assumes that float and double with decimals >= NOT_FIXED_DEC are floating point values (no decimals) - In the .frm decimals=FLOATING_POINT_DECIMALS are used to define floating point for float and double (31, like before) To ensure compatibility with old clients we do: - When storing float and double, we change NOT_FIXED_DEC to FLOATING_POINT_DECIMALS. - When creating fields from .frm we change for float and double FLOATING_POINT_DEC to NOT_FIXED_DEC - When sending definition for a float/decimal field without decimals to the client as part of a result set we convert NOT_FIXED_DEC to FLOATING_POINT_DECIMALS. - variance() and std() has changed to limit the decimals to FLOATING_POINT_DECIMALS -1 to not get the double converted floating point. (This was to preserve compatiblity) - FLOAT and DOUBLE still have 30 as max number of decimals. Bugs fixed: variance() printed more decimals than we support for double values. New behaviour: - Strings now have 38 decimals instead of 30 when converted to decimal - CREATE ... SELECT with a decimal with > 30 decimals will create a column with a smaller range than before as we are trying to preserve the number of decimals. Other changes - We are now using the obsolete bit FIELDFLAG_LEFT_FULLSCREEN to specify decimals > 31 - NOT_FIXED_DEC is now declared in one place - For clients, NOT_FIXED_DEC is always 31 (to ensure compatibility). On the server NOT_FIXED_DEC is DECIMAL_NOT_SPECIFIED (39) - AUTO_SEC_PART_DIGITS is taken from DECIMAL_NOT_SPECIFIED - DOUBLE conversion functions are now using DECIMAL_NOT_SPECIFIED instead of NOT_FIXED_DEC

| | | | | | | | | | | | | | | | | | | | | | Bug #79636: CACHE_LINE_SIZE should be 128 on AArch64 Bug #79637: Hard-coded cache line size Bug #79638: Reconcile CACHE_LINE_SIZE with CPU_LEVEL1_DCACHE_LINESIZE Bug #79652: Suspicious padding in srv_conc_t - changed CPU_LEVEL1_DCACHE_LINESIZE to default to 128 bytes on POWER and AArch64 architectures in cases when no value could be detected by CMake using getconf - changed CACHE_LINE_SIZE definition in ut0counter.h to be an alias of CPU_LEVEL1_DCACHE_LINESIZE - changed a number of hard-coded 64-byte cache line size values in the InnoDB code - fixed insufficient padding for srv_conc members in srv0conc.cc Ported to Mariadb by Daniel Black <daniel.black@au.ibm.com> Added s390 cache size of 256 at same time.
* Reuse THD for new user connectionsMonty2016-06-042-2/+3
| | | | | | | | | | | | | | - To ensure that mallocs are marked for the correct THD, even if it's allocated in another thread, I added the thread_id to the THD constructor - Added st_my_thread_var to thr_lock_info_init() to avoid a call to my_thread_var - Moved things from THD::THD() to THD::init() - Moved some things to THD::cleanup() - Added THD::free_connection() and THD::reset_for_reuse() - Added THD to CONNECT::create_thd() - Added THD::thread_dbug_id and st_my_thread_var->dbug_id. These are needed to ensure that we have a constant thread_id used for debugging with a THD, even if it changes thread_id (=connection_id) - Set variables.pseudo_thread_id in constructor. Removed not needed sets.

This is because - on Solaris with the SunPro compiler, default CMAKE_C_FLAGS_xxx values contain -xO2 (for Release and RelWithDebInfo) and -g (for RelWithDebInfo and Debug) - proper inlining only works at -xO4 without -g - so if CMAKE_C_FLAGS has -xO4, inlining would work in configure.cmake (before this fix) and fail during actual compilation also remove the outdated check for inline from myu_global.h

Add check and related code to use this and only use our replacement if timespec is not defined. - Rename lfind/lsearch to my* to avoid redefinition problems. - Set default value for TMPDIR to "" on Windows as P_tmpdir no longer exists. - using VS definition of snprintf if available - tzname are now renamed to _tzname.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Description: The newest RHEL/CentOS/SL 6.6 openssl package (1.0.1e-30.el6_6.9; published around 6/4/2015) contains a fix for LogJam. RedHat's fix for this was to limit the use of any SSL DH key sizes to a minimum of 768 bits. This breaks any DHE SSL ciphers for MySQL clients as soon as you install the openssl update, since in vio/viosslfactories.c, the default DHPARAM is a 512 bit one. This cannot be changed in configuration/runtime; and needs a recompile. Because of this the client connection with --ssl-cipher=DHE-RSA-AES256-SHA is not able to connect the server. Analysis: Openssl has changed Diffie-Hellman key from the 512 to 1024 due to some reasons(please see the details at http://openssl.org/news/secadv_20150611.txt) Because of this the client with DHE cipher is failing to connect the server. This change took place from the openssl-1.0.1n onwards. Fix: Similar bug fix is already pushed to mysql-5.7 under bug#18367167. Hence we backported the same fix to mysql-5.5 and mysql-5.6.
