* don't issue an error for ER_KEY_BASED_ON_GENERATED_VIRTUAL_COLUMN
* support keyread on vcols
* callback into the server to compute vcol values from mi_check/mi_repair
* DMLs just work. Automatically.
update info->write_end and info->write_pos together, with no
"return on error" in between, otherwise write_end might end up being
smaller than write_pos
Server uses gethostname() for the default base name for pid/log files.
If a character is not representable in current ANSI encoding, gethostname
replaces it with question mark. Thus, generated log file name would also
contain a question mark. However, Windows forbids certain characters in
filenames, among them '?'.
This is described in MSDN article https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx
At attempts to create the file via freopen() fails, thus server would not
be able to start.
The fix is to verify hostname and fall back to "mysql", if
invalid characters are found.
Add support for having multiple IO_CACHEs with type=READ_CACHE to share
the file they are reading from.
Each IO_CACHE keeps its own in-memory buffer. When doing a read or seek
operation on the file, it notifies other IO_CACHEs that the file position
has been changed.
Make Rowid_seq_cursor use cloned IO_CACHE when reading filesort result.
it was supposed to be used in command-line tools only.

Bug#24388746: PRIVILEGE ESCALATION AND RACE CONDITION USING CREATE TABLE
- Moving detection of the MY_CS_CSSORT, MY_CS_PUREASCII, MY_CS_NONASCII
flags of loadable collations from add_collation() in mysys.c
to my_cset_init_8bit() and my_coll_init_simple() in ctype-simple.c.
- Adding tests that these flags are set properly for loadable collations
- Moving LDML test related *.xml files from mysql-test/std_data/
to mysql-test/std_data/ldml/, as there will be more *.xml test files
Move crc32-vpmsum to extra.
Compile static crc32-vpmsum instead of adding sources directly.
Make use of crc32-vpmsum via my_checksum().
Based on contribution by Daniel Black.
Addreses are not necessarily between heap_start && heap_end. Malloc
calls using mmap can place pointers outside these bounds. In this case,
we'll warn the user that the query pointer is potentially invalid.
However, we'll attempt to print the data anyway after we're done
printing everything else.
Fix a bug in testhash.c that caused an out of bounds memory access
when command line parameters specified 0 records to be inserted
in the hashtable.

The check inserts a DWARF directive to tell stack unwinding that the
bottom of the (co-routine) stack has been reached. Without this, stack
traces may attempt to continue past the bottom of the stack.
The GCC version check was incorrect, and failed to trigger for GCC
version 5.[0123].
- 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.
