Description
See http://bugs.mysql.com/bug.php?id=64048
Description:
When requesting debug status output with
mysqladmin debug
the output in the error log (assuming that mysqld_safe was used)
seems to be truncated at first as the mallinfo() related part
is missing, this part will only show up in the error log when
debug is called a 2nd time. This makes the missing part of the
first invocation appear but then again the mallinfo() output
for the 2nd call is missing
How to repeat:
Issue "mysqladmin debug", check output in mysql error log for the "Memory status:"
section ...
Suggested fix:
add an extra fflush(stdout) at the very end of mysql_print_status() in sql/sql_test.cc

Bug#13608112 - 64048: MYSQL_PRINT_STATUS() MISSING FINAL FFLUSH()
|
|
Analysis:
|
While printing debug information, memory related information and event
|
related information were written to buffer after flushing it. Because of this,
|
these information were getting printed when we do the next flush.
|
|
Fix:
|
Instead of calling fflush() before writing memory and event
|
information, calling it after memory and event information.
|
I suppose it will be fixed by the current activity of merging bugfixes from 5.6.
