typo. the code was not matching the comment

fix a buffer overflow in extension_based_table_discovery
(that only happens in debug builds)

Remove Linuxism. 

Works fine with a POSIX-compat shell

don't crash in debug builds. issue an error message on corrupt event

Update sponsors

It could have happened that one of previous tests already executed
buffer pool dump and set the status variable value, so when it's been
checked, the check passes too early, before the dump starts and
the dump file is created. See more detailed explanation in MDEV-9713.

Fixed by waiting for the current time to change in case it equals
to the timestamp in the status variable, and then checking that
the status variable not only matches the expected pattern, but also
differs from the previous value, whatever it was.

In row_search_for_mysql function on XtraDB there was a old logic
where null bytes were inited. This caused server to think that
key value is null and continue on incorrect path.

Logrotate script assumed an error if mysqladmin failed to connect to server
and there's mysqld process exists. However there can be non-system instance of
mysqld running (e.g. in docker) making this assumption wrong.

Check pid file existance instead.

Update AskMonty and Atlassian references to MariaDB

Fix spelling: occurred, execute, which etc

There was a race between end_slave() and cleanup code at the end of
handle_slave_sql(). This could cause access to master_info_index and
global_rpl_thread_pool after they had been freed.

Fix by skipping that cleanup if server shutdown is in progress, as is done
in other parts of the code as well (the cleanup, which stops worker threads
that are not needed anymore, is redundant anyway when the server is shutting
down).

MDEV-9643: Don't emit any "deb-systemd-helper not found" warnings

Index access becomes range every once in a while. Masked the value in addition
to other already masked columns

on FreeBSD 10 jemalloc is in libc, no separate libjemalloc is needed

this simplifies merging of MySQL and TokuDB

"#include <math.h>" has "#define isfinite(X) ..."
while "#include <cmath>" does "#undef isfinite"

in -std=c++11 mode <cmath> is included, we need a workaround
to provide a usable isfinite()

            configured withtout username

Federated/spider/connect engines or replication threads connecting to other host
with empty user name may crash mysqld.

This is addition to original patch, which adds a test case and amends a macro.

This reverts commit 13884cf2.

Fixed in 5.6 (merged in the next commit)

At least on Linux test fails because too small buffer pool.
