All client functions that can block on I/O have alternate _start() and
_cont() versions that do not block but return control back to the
application, which can then issue I/O wait in its own fashion and later
call back into the library to continue the operation.
Works behind the scenes by spawning a co-routine/fiber to run the
blocking operation and suspend it while waiting for I/O. This
co-routine/fiber use is invisible to applications.
For i368/x86_64 on GCC, uses very fast assembler co-routine support. On
Windows uses native Win32 Fibers. Falls back to POSIX ucontext on other
platforms. Assembler routines for more platforms are relatively easy to
add by extending mysys/my_context.c, eg. similar to the Lua lcoco
library.
For testing, mysqltest and mysql_client_test are extended with the
option --non-blocking-api. This causes the programs to use the
non-blocking API for database access. mysql-test-run.pl has a similar
option --non-blocking-api that uses this, as well as additional
testcases.
An example program tests/async_queries.c is included that uses the new
non-blocking API with libevent to show how, in a single-threaded
program, to issue many queries in parallel against a database.

Quick fix: run mysql-stress-test.pl via a wrapper test
Amend mtr to run just that test when using --stress
Updated mysql-stress-test.pl to exit(1) if wrong options

Fixed lp:814237: Wrong mutex usage in Aria
storage/maria/ma_bitmap.c:
Added call to _ma_bitmap_mark_file_changed() when flushing bitmap. This fixes lp:814237
The bug happens when one uses MAX_ROWS=# with Aria & row_format=page and one insert more than # rows.
mysql-test/mysql-test-run.pl:
Ignore table is full error messages
mysql-test/suite/maria/r/max_length.result:
Test case for 'Table is full'
mysql-test/suite/maria/t/max_length.test:
Test case for 'Table is full'
storage/maria/ma_bitmap.c:
Ensure that we don't allocate bits outside of max_data_file_size.
Adjust max_data_file_size based on bitmap alignments.
Backport fix to adjust wrong first_bitmap_with_space.
storage/maria/ma_blockrec.c:
Calculate value of max_data_file_length
storage/maria/ma_blockrec.h:
Updated prototype for _ma_bitmap_init()

Give warnings if file sizes are above max file sizes.
Give more warnings in case of errors.
Have maria_chk write if table is recreated.
storage/maria/ma_create.c:
Better calculation of max_data_file_length and thus data pointer length.
Fixes some wrong pointer lengths when using MAX_ROWS=#
storage/maria/ma_open.c:
Removed duplicate assigment.
Use block size from file instead of global variable.
storage/maria/maria_chk.c:
Remove -1 from printed file length
storage/maria/maria_def.h:
Update struct st_maria_file_bitmap
This patch adds a new client utility that enables or disables plugin
features. The utility disables or enables a plugin using values (name,
soname, and symbols) provided via a configuration file by the same name.
For example, to ENABLE the daemon_example plugin, the utility will read
the daemon_example.ini configuration file and use the values contained to
enable or disable the plugin.
